I was driving on the highway at approximately 60 mph and my check engine and traction control light came on. Additionally, the dash alternately flashed between "service traction control" and "reduced engine power." My car slowed down, but never cut off. My acceleration wasn't what it normally is. I was able to make it to my destination, but was not a fun experience.

2008 an up Chevy Impala traction control light an check engine light plus engine power reduce. Its actually the sensor on your gas pedal what will happened without warning the car will drop to 5 mph. While you are driving and stay like that I took it to the Chevy dealer an they explain to me what's the problem its a very serious defect that can cause a rear end crash to the losing the amount of power. The Chevy dealership explained to me that they have a lot of problems with the Chevy Impala gas pedal.this is a serious issue an need to a recall for these makes an models.

I started the car with the remote start and it was warming up, went out put my two small children I and started it with the key, went back to grab my bag, and got in to go. When I hopped in the message center was blinking; engine power reduced, stabilization track, and something else to do with the traction control. It was very cold out and we had a long drive, I was very scared we would be stranded in the cold. My car has several miles, but has always been taken care of. This is very frustrating, and scary. I have done some research on-line, and it sounds as though Chevy is doing nothing to help the situation, and its happening with a lot of the same year vehicles! I love my car, this is the first big issue, I am so sad about it. I am worried about driving with my kids, from what I have read the car will just turn off! not okay!!! I hope that something; say a recall happens so this can be repaired with few lives lost. Do they want to be like Toyota and all the headache they had!

I was going down the road and out of no where my car says service traction control, followed by service stabilitrak, followed by engine power reduced with a check engine light on. Lost almost all power to the car, could barely turn the wheel and the brakes felt extremely strange. I could only go about 5mph tops down the road. Luckily I was only 2 min from home. Which actually took 6 min because of the reduced engine speed. Right before I pulled in the driveway the motor died. The next day I went out and tried starting it. The remote start wasn't working and my check engine light was still on but it did start up with a turn of the key. I looked up codes and found that it was telling me the accelerator pedal sensor was bad. I have googled this issue and found that it is a very dangerous, common problem with the Chevy Impala. Although that is the code it is giving me, other people have had to replace their throttle body to resolve the problem. GM should recall it before someone gets hurt. I will not be buying another GM vehicle in the future because they are too cheap to fix this common issue which could essentially cost someone their life.

I own a 2008 Chevrolet Impala. Today 11/03/2012 while driving to work the check engine light came on with a message indicating "engine power reduced". I researched the issue and discovered the accelerator pedal sensor is malfunctioning and this causes the message and check engine to appear. This sensor affects the cars drivability and causes limited speed in the vehicle. I looked on google and there are several complaints regarding the same issue. I guess no one has reported it but it seems very common amongst Chevrolet Impala model cars 2006 and up. This is the email link with several other concerns regarding the accelerator pedal sensor: townhall-talk.edmunds.com/direct/view/.F215E7E I also have a problem with my seat belt. The driver??S side seat belt will not fasten without me holding the latch down. This issue started around August 2012 and is a real safety concern of mine. I didn't think much of it because it fastened. But knowing I have to hold the latch down in order for it to click indicates a defect and eventually it may not work properly. Please investigate these issues and if necessary warrant a recall because safety is the number one concern for consumers and if I don't feel safe driving a GM vehicle it will be my first and last time purchasing one.
