Vehicle was in motion in the middle of a very busy intersection, thank god it was at night. The car started violently shaking and the display put up the warning "low engine power" and "service traction control".has happened numerous times before when the car was parked but never while driving. Check engine light comes on for a little bit but then usually goes away after a day or so.

  • 112,000 miles
Last may I was driving my car from work going approximately 40 mph a message came on the information screen. Something about going over 160mph. The car suddenly slowed, couldn't seem to find the proper gear. At the same time the speedometer was going up and down showing 60, 30, 80, 0. then it cut off. I put the rolling car into neutral and started it. It fired up immediately. I put in gear and continued until it was safe to stop. Let engine cool off and drove home. The speedometer continued to fluctuate, it also cut off and flashed the message again. Called dealership next morning and took in. They came back with diagnosis of transmission failure, need to replace. I shelled out $4000 for the transmission, now it is slipping. I drove home today and that message flashed across my screen along with the transmission struggling to find the proper gear. The speedometer was moving up and down. The speedometer was replaced when the transmission was replaced. I have contacted the dealership to schedule an appointment. I also made a formal complaint to GM.

My wife's 2007 Chevy Impala left her stranded on the side of a busy highway in a snowstorm. She was driving at highway speeds when all of a sudden, her overheat warning light began flashing, and what she described as "a huge cloud of fog or smoke" was trailing behind her. She immediately put on her hazards and pulled off to the side of the road. Once stopped, the digital readout showed "engine overheat, idle engine" and then the engine shut off. The vehicle is at a dealer awaiting diagnosis.

Reduced engine power/ traction control warning/ gas line fuel leak. This car flashed a reduced engine power message while I was going 65 mph straight away on busy city (in houston) freeway and the traction control warning light came on. My car then immediately reduced speed and would not go beyond 40 mph. I was told that the gas line fuel leak has nothing to do with it but it seems very coincidental that this all happened in the same day. GM is putting out a lot of trashy vehicles right now and this should definitely be a recall; especially when there are numerous valid complaints of the same issue. I'll never by GM/Chevy again. I am going back to an imported brand

This all started when the factory battery went dead so I went and purchased a new one about a week after I went out one morning to leave for work and it wouldn't start had to be jumped. So later on I checked for a drain on the battery and found out that the radio the interior lights and the display where causing a drain. So I had all three checked all tests fine so I purchased another battery and was good for about a week then all the sudden the radio died and all the auditable sounds stop working the next day went out to try to start the car and nothing happened only had headlights and interior lights wouldn't start. So I put it on a charger for a couple hours tried it again and it was completely dead like there was no battery in. Come to find out that the BCM ( body control module ) was shorted. Now I've got to find a new and figure out how to get it up to dealership to have it programmed

My complaint concerns my 2007 Chevy Impala transmission floor shifter is locking in park.. I could not depress the button on the floor shifter, to shift to reverse. I tried turning the steering wheel which of course is locked when the vehicle is in park. I am worried that next time it will not get unstuck. So I checked the internet and saw many comments about 2007 Impala shifter's locking and realized I needed to file a complaint.

The shift gear has become stuck in park twice. The shifter will not move. I had to have it towed to the mechanic twice in order for the vehicle to become operable again. The shop replaced some wiring and mechanics inside the shift area. Since they have replaced it twice, along with the original parts, I am on the third round.
