In December my car while driving, I experienced reduced engine power the speed immediately dropped without warning and the car cut off. I was stuck in the middle of highway traffic praying that we would not be hit when everyone is doing 70 mph. When the reduced power light comes on the engine light comes on along with the traction light. I took the car to the dealership to only be told that they are not 100% sure what the problem is, but I can start by replacing the PCM module and that may or may not fix the problem. I have a problem with a Chevy dealership not knowing what is wrong with they cars. Especially a car that is having this problem with so many of its car across the nation. This is a huge safety issue. I have been inconvenience since December as I have not been able to drive my car after having this issue and not feeling confident in $1,000 repair that the dealership themselves are not sure is going to fix the issue. I went to the dealership to get to the root of the problem in hopes of getting a solution and solid plan. I think that GM need to be held accountable for this issue and found a good solid solution to the problem and not guessing fixes to make money. We are talking about people lives are being put in danger. Like I felt mine was when you are in the middle line on a highway, where the speed limit is 70 mph and your car reduce power and then shut down.

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

Reduced engine power message came, car stopped suddenly in the street.

- Cedar Rapids, IA, USA

While starting my car the vehicle began shaking and the engine light came on. There was also a message stating engine reduced power. This is not the first time I had this happen. Previously I had this occur and I took my car to get serviced. The mechanic at the repair shop tested for codes and it stated the throttle body. I had that replaced on to turn around and have the same problem two days later. I recently searched this issue online and noticed I'm not the only person with this issue. I called GM and the representative informed me that unfortunately there wasn't a recall on this issue. This is very unsafe and I'm afraid to drive this car. I travel a lot on the freeway and I would hate for the car to stop while driving with myself and children inside. This vehicle complaint really needs to be addressed before someone gets killed.

- Detroit, MI, USA

While driving my vehicle, the traction control light and check engine light came on...then a message stating "engine power reduced" came on. My car dropped the speed from 60 to 20, on the highway. It happened again a month later and I was told that my accelerator pedal needed to be replaced. This happened again in March of this year, and I was told my fuel pump had gone out. Now it has happened again this morning, and the mechanic doesn't know what's wrong with it because it happens intermittently so he can't diagnose it unless it does it while the car is in his possession.

- Memphis, TN, USA

I was driving at 20 mph slowing to turn into my parking lot at work and suddenly the car jolted and the power decreased to maybe half. The car never completely shut off. I was able to coast into a parking spot at work when I tried to accelerate there was no power left at all. All I could do was coast, the car still never completely shut off. This was extremely scarey, I just thank god my 5 year old daughter was not with me at the time!!

While driving the traction control light comes on as well at reduced engine power. It drops the speed of the car down to 40 mph or lower. It does not accelerate easily when coming to a complete stop. This can cause an accident as I have had several near misses. The light will go off if you turn the vehicle off for a few hours but does end up coming back on.
