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?
