I have 3 different complaints. 1. the rotors on my car had to be replaced 3 times before I had driven 36,000 miles. They would wear unevenly, and cause noise and vibrations whenever the brake was applied. 2. the transmission leaked from the pan, and the gasket had to be replaced 2 or 3 times.the transmission still leaks. And the brakes need fixing again, but the warranty expired at 36,000 miles. 3.whenever the engine is under accerlation, my air conditioner does not cool. The vents close off preventing cold air from coming through. How many other owners have reported problems similar to these?
