I just took my 05 GTO with 30k miles to the CarMax for warranty service. The CarMax did not have the proper diagnostic equipment to correct the error (ABS Fault / Brake Warning), so they towed the vehicle to the dealership about 3 miles away. The dealership kept the vehicle over the weekend and then said that the part came in on Monday but was damaged. So CarMax gets my car back today (Tuesday) and gives it to me. I get in and the TRAC OFF will not deactivate and I notice that there is an 80 MILE!, thats right 80 MILE! difference. I look further and notice receipts from the weekend sitting on my seat in a brown paper bag. I didn't leave the lot of the CarMax and immediately went back in to service and they were dumbfounded. We checked all the paperwork together and figured out that the dealer had incurred all the mileage. What recourse do I have?
First check the mileage IN and compare it to the mileage out on the repair order. If they didn't document the mileage IN or fabricated it you'll have no way of verifying your accusation.
Even if its properly documented you will get this ~~ <, >. They will both blame each other. You'll get even more pi$$ed. Their "test" drive to make sure it works could have taken them on a tour of the country.
NEVER EVER EVER take this type car to a run of the mill garage, MOST have NO CLUE on this type car. You are dealing now with a middle man. You buy a cheap insurance policy you get cheap service.
Bite the bullet on this and learn from it. If there is a next time, go to a shop that has expereince on this type car and deal direct and verify mileage with a service manager when dropping off. Most invoices list the service tech's name on it.
Anyone who takes this car to a Pep Boys, or a Walmart, or a K-Mart type place for involved work...money you think you're saving may end up costing you 2x to fix what they may have made worse. Take a look around those places and count how many corvettes or other high end vehicles are in there for work.
