Electric vehicles? Yeah, we service them! ⚡🔧

This Polestar came in for its 40,000-mile service. During our inspection, we found that the front brake pads were seized in the caliper brackets, preventing them from moving freely and causing rust to build up on the rotors.

We were able to resurface the rotors, clean up the brake pad contact points and caliper slides, and get everything moving freely again.

We also performed a brake fluid flush according to the OEM maintenance schedule, replaced a very dirty cabin air filter, and replaced a damaged parking assist sensor.

Just because your EV doesn’t need oil changes doesn’t mean it doesn’t need maintenance!

It’s easy to overlook routine service when you don’t have to worry about engine oil, but regular maintenance is still essential. Tire rotations every 10,000 miles and inspections every 20,000 miles are good reminders to keep your vehicle in top shape, following the manufacturer’s recommended schedule.

With regenerative braking, the conventional friction brakes are used less frequently. That can allow corrosion to build up on brake components, potentially affecting braking performance when you need it most.

Whether you drive electric, hybrid, gas, or diesel-powered, we’ve got you covered! ⚡🚗

We just wanted to come on here and apologize for the content we posted yesterday. We have removed that post and we are very sorry for this.

We felt it was appropriate to make a statement and explain the reason we decided to delete it. When an organization deletes a post and follows up with a statement, people normally pay close attention. We could use your attention at the moment.

We didn't actually delete a post, we just wanted to tell you that....

We are hiring!! The young man that we hired to be a general service technician (oil changes, tires, maintenance work) has done so well and moved through the apprentice program so fast that we want to move him up but we can’t fully do that until we find someone else to take over his position. So if you’re handy like Manny (kids show Handy Manny for those that didn’t get the reference), enjoy working with your hands and want a fun work environment where you can grow your skills while working with and learning from an ASE World Class Technician then go to www.keydiesel.com and apply today! Job duties include performing oil changes, tire rotations, vehicle inspections, mounting and balancing tires, coolant flushes, transmission flushes, fuel injection services, driveline fluid services, and much more.

As Williamston's trusted auto repair experts, we are family-owned and committed to honesty and efficiency. Call us, stop by, or schedule an appointment online!
