PLANNED OBSOLESCENCE: Is Your Vehicle Being Designed to Become Disposable?
From annual styling changes to discontinued parts, software locks and electronic modules — planned obsolescence in the automobile industry may look very different today than it did 50 years ago.
I have been working on vehicles for decades, and something has become increasingly concerning.
Recently, I have encountered customers with vehicles that could otherwise be repaired — except the part needed to repair the vehicle is simply no longer available.
Not temporarily backordered.
Not delayed for a few weeks.
Discontinued. No longer serviced. No replacement available.
Sometimes we're talking about an electronic control module or another component without which the vehicle cannot operate properly.
Think about what that means.
A vehicle can have a perfectly good engine, transmission, body and interior and potentially have many years of useful life remaining. Yet the failure of one electronic component can put the owner in a situation where the manufacturer essentially says:
We don't make that anymore.
The customer is then left searching salvage yards, eBay, remanufacturers and electronic repair companies hoping somebody can resurrect the original component.
That raises a bigger question:
Are automobiles becoming victims of planned obsolescence?
The answer is more complicated than simply accusing automobile manufacturers of deliberately building bad cars.
There is little credible evidence that manufacturers universally design vehicles to self-destruct immediately after the warranty expires.
In fact, many modern vehicles are mechanically capable of traveling 150,000, 200,000 and sometimes 300,000 miles.
But there is another kind of obsolescence developing.
Modern automobiles may physically last longer while simultaneously becoming more difficult to keep repairable.
And that deserves considerably more attention.

What Is Planned Obsolescence?
Planned obsolescence is the practice of designing or marketing a product in a way that intentionally or predictably limits its useful economic life, encouraging the consumer to replace it sooner.
There are several forms.
1. Physical obsolescence
A component is designed with a finite lifespan or constructed in a manner that makes repairing it impractical.
2. Technological obsolescence
New technology makes older technology incompatible or unsupported.
3. Software obsolescence
Hardware continues working, but software updates, servers, applications or digital services supporting it disappear.
4. Parts obsolescence
The product remains usable, but a manufacturer stops producing a critical replacement component.
5. Economic obsolescence
A repair technically can be performed, but the price becomes so high that replacing the entire product makes more financial sense.
6. Perceived or psychological obsolescence
The older product still works perfectly well, but styling and marketing make consumers perceive it as outdated.
Automobile manufacturers have used at least some of these concepts for approximately a century.
What has changed is how powerful they have become.
---
Planned Obsolescence and the Automobile Go Back Nearly 100 Years
The concept did not begin with computers.
During the early automobile industry, Henry Ford famously concentrated on producing a relatively standardized Model T. General Motors pursued a different strategy under Alfred P. Sloan.
Rather than selling essentially the same automobile indefinitely, manufacturers began introducing frequent styling changes, new model years and product hierarchies.
A perfectly functional three-year-old automobile could suddenly look old.
This was an extremely important development in consumer marketing.
Instead of waiting until an automobile was worn out before replacing it, manufacturers could give consumers another reason to buy:
Your existing car is out of style.
By the 1950s, Detroit had turned the annual model change into an art form.
Chrome changed.
Grilles changed.
Tailfins became larger.
Bodies changed.
Colors changed.
Advertisements emphasized what was new.
The old automobile didn't necessarily stop working.
The consumer simply began wanting the new one.
That is classic psychological obsolescence.
In 1932, real-estate broker Bernard London famously proposed the concept of deliberately limiting the useful life of products as an economic response to the Great Depression.
By 1960, consumer critic Vance Packard's book The Waste Makers brought planned obsolescence into mainstream discussion, describing different ways products could become obsolete through function, quality and desirability.
But today's automobile presents opportunities for obsolescence that Sloan could never have imagined.
A tailfin cannot disable your automobile.
Software can.
---
The Modern Vehicle Has Created an Entirely New Problem
Thirty or forty years ago, an automobile was predominantly a mechanical machine.
It contained electrical components, of course, but most systems were relatively independent.
Today a vehicle is essentially a computer network with wheels attached.
Depending upon the vehicle, dozens of computerized modules communicate with one another.
There may be separate controllers for:
- the engine
- transmission
- ABS
- air bags
- electric power steering
- body functions
- HVAC
- headlights
- seats
- instrument cluster
- infotainment
- cameras
- radar
- blind-spot monitoring
- adaptive cruise control
- parking assistance
- battery management
- immobilizer and security systems
That architecture provides incredible capabilities.
It also creates an enormous vulnerability:
What happens 12 or 15 years from now when one of those modules fails and nobody makes it anymore?
That is the question the automobile industry has not adequately answered.
---
The $100 Component That Can Kill a $10,000 Vehicle
This is where parts obsolescence becomes particularly frustrating.
Imagine a 12-year-old vehicle worth $8,000.
Mechanically, it's excellent.
Then a proprietary electronic module fails.
The manufacturer has discontinued it.
The aftermarket doesn't manufacture it.
A used module cannot simply be installed because it contains vehicle-specific programming or security information.
Suddenly a vehicle with years of mechanical life remaining becomes extremely difficult to repair.
The owner may have only a few options:
Find a used module.
Find somebody capable of cloning or programming it.
Have the original circuit board repaired.
Search dealer inventories nationally for new-old-stock.
Or get rid of the vehicle.
That isn't traditional mechanical failure.
That is functional obsolescence caused by the repair ecosystem.
---
There Is No Magical “10-Year Parts Law”
One of the biggest misconceptions in the automotive industry is that federal law requires manufacturers to produce every replacement part for 10 years.
There is no broad federal requirement guaranteeing that every component on every automobile will remain available for 10 years after production.
There are specific protections in certain circumstances.
Federal emissions law, for example, requires extended warranty coverage on certain major emissions components. The EPA states that catalytic converters, the emissions ECU/computer and onboard diagnostic computer receive federal coverage for 8 years or 80,000 miles.
Safety recalls are another category. NHTSA requires manufacturers to provide appropriate recall remedies, which can involve repair, replacement, refund or in rare circumstances repurchase. Federal free-remedy obligations generally extend to vehicles no more than 15 years old when the defect is determined.
But none of this means:
“Every part necessary to keep your vehicle operating must remain available for 10, 15 or 20 years.”
That protection simply does not exist in that broad form.
And considering the price of modern automobiles, perhaps it should.

Eight Ways a Modern Automobile Can Become Obsolete
1. Discontinuing Replacement Parts
This is the most obvious example and the one I am increasingly concerned about.
Manufacturers eventually discontinue components.
For ordinary mechanical components, the aftermarket frequently fills the gap.
Brake pads?
No problem.
Alternators?
Usually no problem.
Wheel bearings?
Probably available from numerous manufacturers.
But what happens when the discontinued component is a vehicle-specific electronic module produced in relatively small numbers?
There may never be enough demand for an aftermarket manufacturer to reproduce it.
This particularly threatens:
low-production vehicles,
short-lived models,
luxury automobiles,
unusual drivetrain combinations,
early hybrids and EVs,
and vehicles containing highly specialized electronics.
The irony is remarkable.
The engine could potentially operate another 100,000 miles.
The vehicle might instead be retired because somebody stopped manufacturing a circuit board.
---
2. Making Components Non-Serviceable
Automotive technicians have watched this trend develop for years.
Something that once contained several replaceable components becomes one complete assembly.
Instead of replacing the failed portion, you replace everything.
Examples can include:
LED lighting assemblies,
electronic steering components,
ABS hydraulic/control assemblies,
electronic thermostat and water-pump assemblies,
electronic parking brake components,
infotainment displays,
blind-spot monitoring assemblies,
camera systems,
and integrated switches and control panels.
Sometimes there are legitimate engineering reasons for integration.
Packaging improves.
Weight decreases.
Manufacturing costs decline.
Reliability can even improve.
But when one $30 internal component fails inside a $1,500 assembly that cannot be serviced separately, the consumer pays for the integration.
---
3. Programming and “Parts Pairing”
Replacing a component once meant:
Remove old part.
Install new part.
Verify repair.
Increasingly it can mean:
Remove old component.
Install replacement.
Connect manufacturer-capable diagnostic equipment.
Establish online access.
Program the module.
Perform configuration.
Perform security authorization.
Perform initialization.
Perform calibration.
Perform relearns.
Sometimes a used component cannot easily be installed because information stored inside it is married to the original vehicle.
There are legitimate cybersecurity reasons for protecting vehicle networks.
A thief shouldn't be able to install an immobilizer module and drive away with your car.
But security and repairability do not have to be mutually exclusive.
The concern begins when technological protection effectively prevents owners and independent technicians from economically repairing vehicles they legally own.
The Federal Trade Commission has specifically investigated restrictions involving proprietary diagnostic tools, limited spare-parts availability and unavailable diagnostic software. The FTC reported in 2021 that there was “scant evidence” supporting many manufacturers' justifications for repair restrictions.
That is significant.
This isn't simply mechanics complaining.
The federal government has examined the issue.
---
4. Secure Gateways and Restricted Diagnostic Access
Modern vehicles increasingly place security gateways between diagnostic equipment and vehicle networks.
Again, cybersecurity is real.
In 2015 researchers famously demonstrated remote vulnerabilities involving a Jeep Cherokee, dramatically illustrating why automobile cybersecurity matters.
Manufacturers responded by improving network security.
That was necessary.
But independent technicians increasingly need accounts, subscriptions, authentication services and manufacturer-specific access just to perform functions that older scan tools could perform directly.
The concern is not that security exists.
The concern is who controls the keys.
If independent repairers can securely authenticate themselves and receive equivalent access, cybersecurity and Right to Repair can coexist.
If they cannot, the manufacturer effectively controls who is allowed to repair the automobile long after the customer has purchased it.
---
5. Cellular Networks Can Make a Car's Technology Obsolete Overnight
One of the clearest demonstrations of digital automotive obsolescence occurred with the shutdown of 3G cellular networks.
Millions of automobiles contained built-in 3G modems supporting features such as:
automatic collision notification,
SOS calling,
remote unlocking,
vehicle tracking,
connected navigation,
and smartphone applications.
The automobiles didn't fail.
The network around them disappeared.
Consumer Reports documented that vehicles from Chrysler, Dodge, Hyundai, Jeep, Lexus, Nissan, Ram and Toyota permanently lost certain connected features. Some affected Nissan and Infiniti vehicles were only several years old. Certain 2019 vehicles were affected.
Different manufacturers responded differently.
Some provided software upgrades.
Some provided hardware upgrades.
Some used adapters.
Others offered no practical upgrade at all.
That is an extraordinary example of technological obsolescence.
A safety or convenience system physically installed in an automobile can become useless because its communications hardware was not designed to be upgraded.
This will become an increasingly important issue as automobiles become dependent upon cloud computing and permanent connectivity.
---
6. Software Can Determine What Hardware You Are Allowed to Use
Automobile manufacturers have discovered something extremely valuable.
They don't necessarily have to sell you another physical component.
They can sell you permission to use one already installed.
BMW generated considerable controversy by offering heated-seat functionality through subscriptions in some markets before abandoning that particular strategy after customer backlash.
Mercedes-Benz has offered paid software performance enhancements.
Tesla has sold software-enabled performance and connectivity features.
General Motors has increasingly emphasized subscription revenue associated with services such as Super Cruise.
Stellantis publicly announced an objective of generating approximately €20 billion in incremental annual revenue by 2030 from software-enabled products and subscriptions, describing tens of millions of connected vehicles as monetizable.
None of those strategies, by themselves, prove planned obsolescence.
But they demonstrate an enormous philosophical change.
Historically:
You purchased the automobile and therefore purchased its capabilities.
Increasingly:
You purchase the automobile, while the manufacturer may continue controlling certain capabilities throughout the vehicle's life.
That distinction is going to become extremely important.
---
7. Technology Can Make Repairs Economically Impossible
Consider modern driver-assistance systems.
Radar sensors.
Cameras.
Ultrasonic sensors.
Electronic mirrors.
Windshield cameras.
Blind-spot sensors.
These systems improve safety.
But they dramatically affect repair economics.
AAA studied modern ADAS-equipped vehicles and found that these technologies can account for up to 37.6% of collision repair costs in the scenarios it examined.
A relatively minor collision can therefore damage equipment requiring replacement, programming and calibration.
Again, this isn't evidence that ADAS was invented to make cars disposable.
It wasn't.
These systems can prevent crashes and save lives.
But there is an unintended consequence:
The threshold at which an older vehicle becomes economically unreasonable to repair becomes lower.
A $1,500 sensor assembly doesn't care whether it's attached to a $60,000 three-year-old vehicle or an $8,000 twelve-year-old vehicle.
Eventually the technology can exceed the economic value of the machine carrying it.
---
8. Software-Defined Vehicles Could Take This Much Further
We are entering the era of the Software-Defined Vehicle.
Manufacturers increasingly envision automobiles as hardware platforms whose functions evolve through software.
There is tremendous potential here.
Software updates could actually extend vehicle life.
Manufacturers could fix bugs remotely.
They could improve functionality.
They could add compatibility.
They could update cybersecurity.
That would be the opposite of planned obsolescence.
But there is another possibility.
What happens when the manufacturer stops supporting the software?
What happens when authentication servers disappear?
What happens when the cloud service required by a feature shuts down?
What happens when replacement hardware requires authorization from infrastructure that no longer exists?
What happens when an automobile is 20 years old but its software ecosystem was designed around a 7-year business plan?
Those questions should be answered before, not after, millions of these vehicles reach middle age.
---
One of the Most Interesting Examples: Tesla's eMMC Recall
There is a particularly interesting real-world example demonstrating how the lifespan of a tiny electronic component can affect an entire automobile.
Certain older Tesla Model S and Model X vehicles used an 8GB embedded multimedia memory device in their Media Control Unit.
Repeated writing to the memory caused accumulated wear.
Eventually the memory could fail.
That could cause the center display to become blank and affect access to functions including the backup-camera display and defrost/defog controls.
The issue became serious enough to result in a recall.
The repair included upgrading the memory capacity from 8GB to 64GB.
This does not prove Tesla intentionally designed the component to fail.
It does demonstrate something extremely important:
A relatively inexpensive electronic memory component with a finite write lifespan can affect the usability and safety functions of an entire automobile.
That is the world vehicles now inhabit.
---
So Which Manufacturers Are Practicing Planned Obsolescence?
This is where we need to be careful.
I don't believe the available evidence supports publishing a list saying:
“Manufacturer A deliberately designs cars to die early, Manufacturer B doesn't.”
Proving intent is extremely difficult.
What we can identify are manufacturer practices that create greater obsolescence pressure.
Those include:
aggressive software monetization,
proprietary programming,
parts pairing,
limited repair information,
secure-gateway restrictions,
discontinued electronic components,
non-upgradable connectivity,
assembly-only replacement strategies,
and limited support for older technology.
Some manufacturers have demonstrated concerning examples in these areas.
But almost every major manufacturer now participates in at least some of them.
And there are important counterexamples.
---
General Motors
"General Motors" has moved aggressively toward software-defined vehicles and recurring digital revenue.
Its Super Cruise technology, for example, is offered with subscription pricing after complimentary periods on applicable vehicles.
GM has also moved away from Apple CarPlay and Android Auto in newer vehicles as it develops a more vertically integrated software ecosystem.
That creates legitimate questions about how much control a manufacturer should retain over a vehicle's digital environment.
At the same time, GM continues supporting an enormous population of older Chevrolet, GMC, Buick and Cadillac vehicles, and the aftermarket for high-volume GM vehicles is among the largest in the world.
So labeling GM itself as a “planned obsolescence company” would oversimplify the issue.
---
Stellantis / Chrysler / Dodge / Jeep / Ram
"Stellantis" has been particularly open about the financial potential of connected vehicles.
The company has publicly targeted billions of euros in annual revenue from software-enabled services and subscriptions.
Stellantis was also an early adopter of secure diagnostic gateway technology.
Again, cybersecurity provides a legitimate justification for authentication.
But from the independent repair perspective, every additional layer between a technician and the automobile creates another potential future failure point.
What happens when today's authentication infrastructure is needed to repair a 20-year-old Jeep?
Nobody knows yet.
---
BMW
"BMW" became the poster child for automotive subscriptions when consumers discovered that certain hardware already installed in vehicles could be activated through recurring payments.
BMW ultimately backed away from the controversial heated-seat subscription model.
That's actually an encouraging example of consumers influencing manufacturer behavior.
But the episode revealed something important:
Automakers now possess the technical ability to control vehicle features after the sale in ways that were impossible in the mechanical era.
---
Tesla
"Tesla" represents both sides of this argument.
On one hand, Tesla has demonstrated the tremendous benefit of over-the-air software updates. Vehicles years old can receive new functionality without visiting a repair facility.
Tesla also makes service information available and says parts can be purchased through several channels, including directly from Tesla.
On the other hand, Tesla's vehicles are extremely software-dependent, and the eMMC recall demonstrated how electronic hardware longevity can affect essential vehicle functions.
Tesla therefore demonstrates both the best promise and biggest risk of software-defined automobiles.
---
Toyota Offers an Interesting Counterexample
"Toyota" deserves mention because it demonstrates why accusing the entire industry of intentionally shortening vehicle life would be inaccurate.
Toyota created its GR Heritage Parts program specifically to reproduce certain discontinued components for older enthusiast vehicles.
The company has reproduced parts for vehicles including older Supras, Land Cruisers and other historically significant models.
That doesn't guarantee parts availability for every Toyota ever manufactured.
But philosophically it recognizes something important:
A manufacturer can decide that keeping old vehicles alive has value.
Other manufacturers should take notice.
---
Porsche May Be the Strongest Counterargument of All
"Porsche" operates one of the most impressive classic-parts programs in the automobile industry.
Porsche states that its Classic organization maintains approximately 80,000 genuine parts, specifically supporting older vehicles.
The company also notes that more than two-thirds of all Porsche vehicles ever produced remain on the road.
Think about the difference in philosophy.
Instead of saying:
“Your car is old. Buy another one.”
The business opportunity becomes:
“Your car is old. Let us help you keep it alive.”
That is the opposite of planned obsolescence.
"Mercedes-Benz" likewise maintains a dedicated Classic genuine-parts operation supporting older vehicles.
Manufacturers clearly can provide long-term support when they decide it is worthwhile.
---
The Real Problem Isn't That Cars Don't Last
This is perhaps the most important point in this entire discussion.
Modern automobiles aren't necessarily wearing out faster.
In many respects they're lasting longer.
Engines routinely travel mileages that would have been extraordinary several decades ago.
Corrosion protection has improved.
Engine management is dramatically better.
Lubricants are better.
Manufacturing tolerances are better.
Fuel injection eliminated many problems associated with carburetors.
Modern transmissions can last tremendous mileages when properly designed and maintained.
The problem is changing from:
“Will the car survive?”
to:
“Will we still be able to repair it?”
Those are very different questions.
A 20-year-old automobile with a worn water pump is repairable.
A 10-year-old automobile needing a discontinued proprietary computer may not be.
Mechanical longevity means very little if electronic repairability doesn't accompany it.
---
Why Right to Repair Has Become So Important
This is precisely why the Right to Repair movement matters.
The issue isn't simply whether your neighborhood mechanic can compete with a dealership.
The bigger question is:
Who controls the useful life of a vehicle after it has been sold?
The owner?
The manufacturer?
A software server?
A subscription?
An encryption key?
A cellular provider?
A discontinued microprocessor?
Congress is currently considering federal Right to Repair legislation for automobiles. The REPAIR Act introduced in 2025 seeks to ensure consumers have access to vehicle-generated data, repair information and tools. As of 2026, the legislation has advanced through a House subcommittee but has not become federal law.
Regardless of what legislation ultimately passes, the debate itself demonstrates how dramatically automobile ownership has changed.
Twenty-five years ago, Congress didn't need to debate whether your mechanic should be able to digitally communicate with your door module.
Today it matters.
---
Is This Really Planned Obsolescence — or Just Technological Progress?
Sometimes it is simply progress.
That distinction matters.
Using plastic instead of aluminum isn't automatically planned obsolescence.
Installing an electronic throttle isn't planned obsolescence.
ADAS isn't planned obsolescence.
Turbocharging isn't planned obsolescence.
Secure diagnostic networks aren't automatically planned obsolescence.
Even discontinuing a rarely purchased component isn't necessarily malicious. Manufacturing tooling disappears. Suppliers go out of business. Semiconductor manufacturers discontinue chips. Maintaining inventory indefinitely is expensive.
We shouldn't label every engineering compromise a conspiracy.
But manufacturers also should not be allowed to hide behind technological complexity when reasonable design choices could keep automobiles repairable longer.
There is a difference between:
“This component eventually failed.”
and
“This component failed and the manufacturer has created no practical way to repair or replace it.”
The second situation is where consumers should start asking questions.
---
What I Believe Manufacturers Should Be Required to Do
If manufacturers genuinely want to demonstrate that planned obsolescence isn't their objective, there are some relatively straightforward principles they could support.
Critical components should remain available for a reasonable portion of a vehicle's expected life.
A modern automobile should reasonably be expected to remain serviceable well beyond the warranty period.
Electronic modules should be repairable or replaceable.
If a module is discontinued, manufacturers should provide enough technical information for qualified companies to rebuild it.
Replacement modules should remain programmable.
Programming servers and authorization systems should not become an expiration date for otherwise serviceable automobiles.
Used components should be reusable whenever safely possible.
Security systems can provide controlled authentication without permanently marrying every component to one vehicle.
Cellular hardware should be modular.
A $50 communications modem shouldn't obsolete a $50,000 automobile's connected safety systems.
Software support periods should be disclosed when the vehicle is sold.
If connected services will be supported for only eight years, tell the customer that before the purchase.
Non-serviceable assemblies should be minimized.
If an inexpensive internal component can reasonably be replaced, consumers shouldn't necessarily have to purchase an entire assembly.
Independent technicians should have meaningful access to repair information.
Not theoretical access.
Not a maze of subscriptions and proprietary hurdles.
Practical access.
---
Consumers Should Start Asking a Different Question
When people shop for automobiles, they usually ask:
Is it reliable?
What fuel economy does it get?
How much horsepower does it have?
What is the warranty?
How much is the payment?
Maybe we need another question:
“Will somebody still be able to repair this thing 15 years from now?”
Before purchasing a used vehicle — particularly a low-production luxury vehicle, discontinued model, early EV or highly computerized vehicle — parts availability deserves consideration.
Look at the price and availability of:
headlights,
tail lamps,
electronic modules,
infotainment systems,
ABS components,
ADAS sensors,
HVAC controls,
battery packs,
charging components,
and model-specific electronics.
A $15,000 used luxury vehicle containing a $4,000 discontinued headlamp is not necessarily the bargain it appears to be.
---
The Automotive Industry Has Reached a Crossroads
Automobile manufacturers have accomplished remarkable things.
Vehicles are safer.
Cleaner.
More powerful.
More efficient.
More comfortable.
And in many ways more durable than ever.
But technological progress should not require making automobiles disposable.
We are approaching a point where the limiting factor in a vehicle's lifespan may no longer be its engine or transmission.
It may be software support, electronics and replacement-parts availability.
That's an enormous change.
A vehicle should not become mechanically worthless simply because a manufacturer stopped producing one circuit board.
A customer who spends $40,000, $60,000 or $80,000 on an automobile should have some reasonable expectation that the manufacturer has considered how that automobile will remain repairable after the original warranty expires.
Not forever.
But certainly for a meaningful portion of the vehicle's potential life.
---
From Tailfins to Firmware
The original automotive version of planned obsolescence was relatively harmless.
Manufacturers changed styling so your old car looked old.
You could ignore them and keep driving it.
Today's version has the potential to be very different.
A discontinued module can actually stop the vehicle.
A software server can determine whether a replacement component works.
A cellular-network shutdown can eliminate features overnight.
A proprietary diagnostic gateway can determine who repairs the vehicle.
An integrated electronic assembly can turn a small failure into a multi-thousand-dollar repair.
And software can determine whether hardware physically installed in your automobile is even available for you to use.
That's why I don't believe the biggest question is:
“Are manufacturers deliberately building cars that won't last?”
The evidence doesn't justify making that accusation across the board.
The better question is:
“Are manufacturers designing today's vehicles so that they can reasonably remain repairable for as long as the mechanical vehicle is capable of lasting?”
On that question, I believe the automobile industry still has a lot of work to do.
Because the ultimate measure of automotive durability shouldn't simply be whether an engine can reach 200,000 miles.
It should also be whether, at 200,000 miles, we can still get the parts and information necessary to keep the rest of the vehicle alive.
And increasingly, that may become the difference between owning an automobile and merely owning a machine that works for as long as its manufacturer continues supporting it.
