Was driving on busy one lane road, reduced speed, check traction control, check engine light came on and car slowed down to 45 and would not go any faster, was able to pull off of road and shut car off started about 5 minutes later no indication of the problem. Two days later the problem came back. Went to internet to check problem seems like there have been 100,000 S of these problems many resulting in accidents. It does not show that there has been a recall. This is very serious if I would have been on a freeway with trucks traveling at high speed I could have been killed. What has the vehicle safety board done to protect owners of faulty vehicles?

Difficulty shifting into gear from park with vehicle started or off when depressing brake. Shift lever was locked and would not move. On 3/16/2014 it completely locked in park position. I called road service and they removed part of console cover and found wire had broken in wire harness (black) which controls release of gear shift while depressing brake pedal. They showed me how to depress release button for parking gear. I had to do this for 3 days manually till I could get a electrical shop repair the broken wire subsequent wire harness as they told me it was not feasible to replace just the black wire to the park gear release. It cost me $465 for repairs. I checked on line and found this has been a quite a problem with 2008 Chevy Impala's and is happened quite frequently. My question is why GM has not issued a bulletin due to this problem to correct it. To be stranded and in the dark is quite a frightening situation.

I own a 2008 Chevy Impala which has been having computer problems for 1 yr now. It reads out reduced engine power and the car wont go faster than 40 mph. Ive had it fixed but then comes right back up, one mechanic says to clean the throttle and another says its sensors. This is becoming quite a problem and nobody can fix it permanently. It is a serious saftey issue due to the fact that I Transport grandchildren around and the car looses power out of nowhere, then just shuts down in the middle of traffic. I cant keep paying all this money for it to just happen over and over with no results. When is this going to be on the recall list" I went online to find out there are alot of other people having the same exact issue. Please help me" I cant afford to keep paying for this when its never actually been fixed. I have no problem paying to have my car fixed but I do when I have to pay over and over again and its still not fixed.

While accelerating the car lost the ability to continue accelerating all at once which caused a jerking motion of the car causing me(the driver) to be thrown forward hitting my head on the steering wheel. It all happened very fast and the reduced engine power and traction control message appeared on the dash board and is still on the dash board. As I said it all happened very fast but I was able to brace myself slightly which is the only reason I was not seriously injured. This issue which now after speaking to my car mechanic and me seeing many other people having the same issue after doing some research online is a death sentence to someone. Someone is going to die from the car losing the ability to accelerate all at once along with a jerking motion that makes you want to have a foot on the gas and a foot on the brake to be able to stop should the car take off on it own.

In June 2012 I had this problem error message read: "engine power reduced " as I was driving 55 mph on highway mph fell below to 40 I had to get off highway. I had this problem fixed so I thought it cost me about 360 dollars. Same exact recurring problem same error message today 12/09/13. This is ridiculous GM has to know this is not safe. Dealership will not repair again at their own expense. Too much money for me to continue paying over N over again. They need to recall this car it's outrageous! can someone please help us?!

I turned my car on, put on my seat belt, put my foot on the brakes, and tried to shift my car out of park and into drive. I could not push the button on the shifter in, and the shifter would not move out of park. I researched the problem and found that there is a quick release button underneath the center console on the passenger's side. I had to put my emergency brake on, turn on my car, have someone reach under the center console from the passenger's side to press the button, and shift into drive while they held the button. I still am unable to shift my car out of park unless someone is holding that button.

Since I have owned the car, it gets randomly stuck in park. It usually is in a driveway on a slight incline. It takes 20 or 30 minutes of pushing the brake and starting and restarting to finally get it to shift from park to drive. The last time this happened it was definitely a safety issue. I was on an interstate driving in the fast lane when I came upon stopped traffic. There was a bad accident ahead and traffic was not moving at all. After about 20 or 30 minutes I turned my car off and waited for traffic to start moving. When traffic started moving, I tried to put my car in drive and it would not move. I was not on an incline. I was on level ground. I was in the fast lane and here I sat unable to move at all, could not pull of the road. Irate drivers and 18 wheelers coming up on me at 70 mile an hour. I was so scared, I thought I'm going to get killed and so is the driver that crashes into me. I did everything I knew to do and after about 20 minutes it finally went into gear. Had it not, I was going to abandon the car because I knew it would get creamed. My only concern was the person that would hit the abandoned car would be hurt or killed. When I got home I called the GM customer service and was told to take it to my local Chevy dealer. I took it to them as well as another mechanic and was told, I would have to bring it in when it happened because they could not get it to do it again so they couldn't repair it. Well duh, if I could bring it in when it happened I wouldn't have a problem. One told me if it was a stick shift, he would know what it was but since it was on the column, he had no idea. After spending money and time I still have a major safety issue in my eyes.

I was driving about 50 miles an hour and "service traction control" and "reduced engine power" lights came on. I slowed down to 40 and was trying to merge into traffic and the car downshifted really hard and died. Right as it died another light came on, something about the throttle. I was on a 4 lane bridge during rush hour. Had the car towed to the local Chevy dealer. When they got it, it started right up, but the check engine light was on. They had the car for 3 days and could find nothing wrong with it. Since then it has happened 5 more times.

I had just started my 2008 Chevrolet Impala ltz and was leaving when the service stabilitrak warning came on and engine power was reduced warning came on. The vehicle lost power and began to jerk as it shifted gears. Unfortunately, it occurred at a time when the local Chevrolet dealer's service department was closed and on the weekend. I'm hoping to get this problem resolved on Monday as this is my only mode of transportation and I'm 8 weeks from graduating from college!! it would suck if I have spend all this time and money in getting my education only to fail due to a vehicle breakdown that seems to be an issue with this very make and model. This could be a very dangerous situation for anyone having this problem with their Impala. It shouldn't take a loss of life or injury, fire or crash to make the manufacturer place a recall on the faulty part that is causing this.
