Back in January 2012, I bought a Chevy Cruze 2012 with automatic transmission. After two month using this vehicle, I found out it has a problem while driving up/down hill. Driving uphill, once I put the transmission into drive and release the brake pedal this car rolls back and the engine cut off. Driving downhill, once I put the transmission into rear and release the brake pedal this car goes down and the engine cut off. I went to a Chevrolet dealer, they tested my car and another 2012 Cruze from their inventory and both cars did the same as I describe above. However, they told me the car is performing as designed and no problems found at this time. Then, I contacted GM, GM contacted its dealer, and three days later GM called me back telling me the same 'no problems found'. so, I requested a letter where GM tells me that anything was wrong and they will cover any future issues with the automatic transmission but GM told me that they cannot provide me any document. As a customer, I would like to request an investigation because in my opinion those issues are design defects. Thank you in advance for your help.
