Lemans Chevrolet City

Bought a used car here on Labor Day. Took the car on a predetermined test drive route directed by our salesman. . Everything seemed to be in good working condition so we bought the car along with a warranty that the finance manager said was REQUIRED before the bank would approve the loan. It’s was fairly cool temps so we didn’t run the AC on the way home only during the 10 min test drive. The next day was very warm so we used the AC and approximately 20 mins into the drive, the AC quit working. I called the dealership and scheduled a service appointment. They said the AC compressor was bad and replaced it. The next day the AC starting doing the exact same thing it was doing prior to changing the compressor. They diagnosed it AGAIN and said the expansion valve was actually the problem and they would need over $2000 to repair and warranty would not cover. The part is fairly cheap but they don’t want to eat the labor costs. I’ve reached out my phone and email and no one will return my calls. This is the service you receive when you buy a car from these people. Honesty and integrity are not found at this dealership , I’d continue looking somewhere else before buying ANYTHING at Lemans Chevy.
