Most of you that know us, or do business here at Lair Diesel Repair, know that we enjoy educating our customers on things we know from experience to help our customers make the best decisions when it comes to their vehicles.
Recently we have had some experience dealing with Vehicle protections plans. You know, the ones that a dealer will add to the cost of the vehicle to give you "Peace of Mind" when it comes to vehicle repairs, which we all know can be costly. Especially when we're talking about diesels.
Please don't waste your money on these. They are nothing short of a scam. You can read all the fine print, and think you're smart enough, or maybe tough enough to know what you're buying, and to be able to get what is deserved out of these types of policies, but you won't get much of anything.
We recently had a customer buy a Duramax with a broken crankshaft from a dealer. He had purchased an extended warranty for an additional $5,000. The engine repair was going to cost nearly $20,000. Luckily, he had that insurance to cover an engine, right? Wrong. They said the policy had a maximum benefit of $6000. So they suggested we find a used engine. Ok we did that which as you can imagine the junkyard engine lead to numerous unforeseen problems that we took care of. In the end we managed to get the truck back up and running for around $15,000. So he paid the bill and the repair plan denied the claim completely.

The next customer had a policy that cost $4000.00. He had a wheel bearing go bad. After hours of jumping through hoops they offered to pay $200 under our cost for the part with no markup and half the labor on the bill at a reduced labor rate. The $900 job got a payout of $428 after a $100 deductible.

In either case keeping the money spent on the "Protection Plan" would have been more beneficial to the customer than having the plan. I didn't even calculate any interest on these policies, and knowing most people are adding this cost to the loan for the vehicle this cost is astronomical. These plans are a false sense of security and really should be labeled as FRAUD, and or Larceny/Theft by deception. Again, Please don't fall for these bogus repair insurance policies. There is no Santa Claus, Easter Bunny, or Repair Protection Plans. If you have already purchased one, I'm sorry and I don't blame you, I don't think less of you, you didn't know better. Now you do.

If you work for one of these companies, or sell these policies, shame on you.

At Lair Diesel Repair we aren't just working on engines and transmissions. This truck we're working on got the full HVAC treatment. Axil pulled the dash for me, I rebuilt the heater box with new aluminum blend doors (instead of the plastic ones that break, new heater core and AC evaporator core, and removed whatever creature nests were in there, and refoamed the seals. While we were at it we replaced the cracked dash top with a new abs plastic one from Genos Garage! We are also putting an android stereo with gps and a backup camera, along with some kicker speakers all the way around. You just never know what I won't say no to.

By the way, That's "Camera shy Casey" from O'Smiley auto parts in Estherville. If you know him tease him about it. He generally takes it pretty well!
