I have had this reduced engine power/service traction control message before with this car. A few years ago I had it cut off on me in the middle of a side street. Thankfully it wasn't a busy street. But I've never felt threatened until this morning. I came to an intersection of a busy highway when I got the message. I needed to cross over to the other side. As I began to cross I was in the cross-hairs of a trash truck on one side and a car on the other. I tried to floor it but my car didn't respond as normal. It truly was reduced! thankfully all the other vehicles performed as they should.

The service traction control light comes on and the engine power reduced message appears. The entire car shuts down and you can not accelerate. I was on the freeway and could have been hit from behind. I immediately put on my hazard lights and pulled off to the side of the road. This was the first time, happened again this month(March). Taking to Chevy dealer for a diagnosis.

While driving 65mph on highway 526 in SC, our 2008 Chevy Impala experienced reduced engine power and a traction control error message appeared on the dash. The vehicle lost engine power and my wife, daughter and I were almost rear ended. We have now spent hundreds of dollars trying to repair the issue but with no solution in sight.

I purchased a Chevy 08 Impala in late January 2013 with less that 55K mile on it, now it's been about a year it's around 64K mile. Today on my way to work, the traction control light and engine light are on and there are the message of traction control is on and also the engine power is reduced. I felt the speed of the car reduced, luckily I am on local street without many traffic. After about an hour I tried to tested it again and only the engine light is on, the speed of the car is normal. I am not familiar with car problems and also it's my first time to own a car. But I read a lot posts online [xxx] and found so many people experiencing the similar problems. The same problem would later happen in my situation. I am disappointed to learn that GM hasn't resolved this issue. I hope I could fix it soon.

I was driving at highway speed (60 mph) on a two lane road. Temperature was below freezing, no ice or snow. Suddenly a bell sounded, the "service traction control" blinked on the display, the traction light came on, and then the vehicle suddenly reduced power, and "engine power reduced" displayed alternately with the "service traction control" warning. I was scared, but had about 8 miles to drive to my home town. I pulled to the shoulder at about 40 mph, turned on my flashers, and continued on to my home. If this had happened with ice on the road, as there had been that morning on my way to work, a crash would no doubt have occurred as these roads are very slippery in winter.

While driving at 60 mph the cars service traction control light comes on and so does the ABS brake service light. The car then reduces power to no more then 35-40 mph and that's with the gas pedal floored. It has happened since new. I have changed out the harness, and wheel hub and it still happens, sometimes in very dangerous situations like while driving on a hwy with a truck behind you and the car goes from 60 mph to 40 mph in a heart beat. The dealership said its a common electrical problem with GM cars in 2006-2009. The only part left to change would be the computer modulator, however talking to other GM owners with the same problem it doesn't seem to help.

Traction control loss of power while driving warning lights.

- Petaluma, CA, USA

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.

I have a 2008 Chevy Impala, nice car unless it snows. It is undrivable in the snow. Its like driving on ice, I have never ever had any car handle like this. It is the most unsafe car I have ever driven. Something needs to be done the dealer says to bring it in next time it snows, well I can't, I will not drive it in the snow. I have been in the ditch 3 times this winter ( and its only the first of January)and each time I was only going no more than 30mph and swaying all over the road, all the other cars were moving along normally it wasn't bad out, just a little snow. It's like driving on ice...

2008 Impala has bad gas pedal while you are driving the traction light and engine light comes on you lose a lot of the engine power until the traction light goes off this is very dangerous. I called GMC and took it to a dealer they put it on the machine first I was told it was sensor in the pedal. Next I was told it was the wiring harness. By the same dealer now I don't know what to do I think something dangerous should be fixed by the dealer but they say it is not covered.

2008 Impala ls, with new tires. Have never driven a car that handles worse in the snow. The traction control system is a joke. It actually makes driving in the snow unpredictable and unfamiliar. I am very experienced on ice and snow but this car makes me feel unsafe because it is. I wish I would have never purchased this car based on this reason. All this in only 1 1/2 inches of dry snow.

I purchased my 2008 Impala with 28K miles in March 2009-certified used. I had to replace the tires within the first 6 months of ownership ( I was told that GM uses cheap tires. From the outside the tread was fine and it appeared to be in good shape but when it was on the lift the told me they all had metal showing. I paid this car off and gave it to my son in April 2010- he has since changed all 4 tires back tires 3 times. We had them rotated and aligned twice, that is when it was discovered that the tires had worn on the inside again. There is no way to know unless it is on a lift. My son took the Impala to the dealer service yesterday and purchased his 2 tires- it was agreed by service manager that if we took the car there and bought tires from universal that he would put them on, do an alignment and most important install the camber bolt kit at no extra charge. This was also told to Chevy by (the service manager) when they called him. I didn't go with my son to pick up the car- I did however pay the $350 which was the price agreed imagine my complete anger when I found out last night the camber bolt kit was not installed and all that was done 2 new tires and an alignment! I could have done that down the street for less money. I expect GM to do a recall and fix this suspension issues- we have replaced tires 3 times in the last 6 months and aligned 2 times. What kind of nonsense is it to tell my son he doesn't need the kit" after so many complaints of the same issue\GM issued a tsb #08032 for police Impala that are on the same platform and suspension, but never extended that to the public. Seems to me that the rear suspension has an severe defect that can cause tire blowout without warning. No tires should wear like that with less than 17,000 miles without a rear suspension and alignment problem that needs to be recalled for repair and replacement of the parts and tires. Does someone have to die due a defect on the car itself" this has to be fixed for everyone.

Car has no traction. The least bit of snow and I can not even get out of my own driveway. The car slides left and right no matter the amount of snow. Tires spin with only a slight covering of snow on the road. Tires spin when there is only wet pavement.
