Also please check out the statistics and reliability analysis of Chevrolet Cobalt based on all problems reported for the Cobalt.
Once car warms up, while driving, the automatic transmission does not shift past second (2nd) gear, and will allow red lining without shifting up a gear. When trying to park, the shifter will not allow shifting into park, and the vehicle will pull away under the power of its own idle if the parking brake is not applied, making leaving the vehicle unattended very dangerous. When trying to shift out of park shifter will become stuck in the parking gear. The light illuminating and indicating the gear in which the shifter is in position of goes out, making it very difficult to know if the vehicle is actually in park or reverse especially coupled with the shifter not going fully into the parking gear. When the shifter doesn't quite move into the parking gear it causes the doors to stay locked and sometimes makes the manual locks difficult to use in order to exit the vehicle, it makes the electronic locks completely unusable. Also, why in the world would chevy not put a engine temperature gauge in the dash cluster? how are drivers supposed to know if the engine is overheating, wait until the engine blows up with the driver trapped inside???.

I was trying to start my car and turned the key in the ignition and my car was completely dead. I thought it was the battery and tried to take the key out, but it was stuck and wouldn't come out. I googled how to take it out and that worked, we jumped the car thinking it was the battery, but without the key in the ignition, the lights and electrical allturned on. This tells me that the car's ignitor/shifter was stuck in the "on" position. It could have been a dangerous situation if I were anywhere but home.

Shifting I threw the gears quickly to get up to speed of traffic. The shift linkage breaks and car is either stuck in gear or neutral with no acceleration causing traffic to break heavy or accident behind vehicle. Replace under warranty with similar parts but still same plastic ends and clips should me metal on drive line parts.
