general problems of the 2008 Chevrolet Impala - part 2

The contact owns a 2008 Chevrolet Impala. The contact stated that while driving 60 mph, the engine power reduced warning light illuminated and the vehicle decelerated. The manufacturer was not made aware of the failure. The vehicle was not diagnosed or repaired. The failure mileage was 200,000 and the current mileage was 210,000.

I have had the ignition switch repaired under the the recall thinking this might help the problem. I will be driving down the road when the steering will lock up and the car slows and cuts off. I have had several near miss accidents with other cars and am literally afraid to drive the car anymore. I have taken the car to several other dealers and they claim they are unable to determine what is wrong or how to fix it. It is only a mater of time before I have an accident and injure myself or others .

While driving to work on 29 may 2014 I hit a small pothole. The pothole is 10" across, 3-4" deep, and I hit it head on. This caused my car to shut off, which I didn't realize until until I tried to accelerate. I then realized I had no power steering or breaks and had to pull off to the side of the road to restart the car. Luckily there were no cars behind me, so other than having to pull off the road on a curve I was lucky. I called both my local gm dealer (ressler of bozeman, mt) and gm customer support to tell them about the issue. The local dealer told me there was no issue with the car, no recalls, and nothing to worry about. The technician told me to "avoid hitting potholes". Given the state of the roads that may be hard to do. The gm support told me there was no recall at the moment but there might be one down the road and to watch the news.

This is the second incident we have had with our 2008 Chevrolet Impala where this problem has occurred. The most recent incident was on Wednesday may 21st, around 730 pm. My wife was driving on a road with a posted speed limit of 45 miles per hour, she said she was going about 48 when the traction control light came on, and the messaging system indicated "reduced engine power. " when this happens the vehicle slows rather rapidly, and then it is impossible to accelerate beyond about 30 miles per hour or so. Due to the rapid decline in speed and the fact that this occurs without warning, I believe this should be an immediately acted upon problem. I contacted gm only to be told that I have to take it to get it looked at by one of their local dealerships, and pay for that diagnostic. In my online research I have discovered many, probably in the hundreds, who've experienced this identical issue. Some of which have take their car to gm who has concluded according to post of experiences on edmunds that they were unable to determine the source of the problem or repair it. This is a problem that require immediate attention. I can't imagine how differently this could have gone should my wife have been going 75 mph on interstate 80. We live along I-80 and travel it frequently. However as a result of this problem we are essenitally unable to trust our vehicle beyond about 50 miles per hour.

Tl- contact owns a 2008 chevey Impala lt. The failure occured April 2014. The contact was driving and you hit a pothole. The contact stated that they had to put on hazard lights on. The contact brakes failed after hitting the pothole, preventing her from stoping the vehicle. The contact stated the key ignition failed. The current millage is 109,000. The contact called the manufacture. There were no repairs made on the vehicle.

Driving down the highway and the engine slows down , then the reduced speed light comes on. The engine power is very slow almost got rear ended. I have read on line that this has happened alot to this paritcal vehicle, why hasnt chevy recalled any yet . This should be a safety hazard.

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.

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. . Read more...

The vehicle was not taken to the dealer for inspection. The manufacturer was made aware of the failure. The vehicle was not repaired. The failure and current mileage was 128,000.

My engine power reduced light keeps coming on and the power is significantly affected. I can set my cruise and then without warning the light comes on, cruise stops working and car slows down. This is a hazard in fast moving traffic. It appears that this is a very common problem among 2008 model Impalas.

The vehicle was not taken for diagnosis or repairs. The manufacturer was not made aware of the problem. The approximate failure mileage was 100,500.

I was driving about 35 mph the entire car system shut off , no warning lights came, I rolled into a dirt parking lot, and turned the key off, sat there for a little while then continue to work, had to take alternate route, didn't know when or if it would happen again. It did happen again later that afternoon, while autozone tech was checking my battery. It was frightening, thank god!! traffic was light. I live where a lot of big rigs come and go, I mostly drive freeways, but that day I had to change my route.

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 have a 2008 Chevrolet Impala ltz. I have had several occasions now when my car has started flashing "service stabilitrak" "engine power reduced" "service airbags" and then all the corresponding lights come on. One of the times the vehicle flashed all of those warnings, the lights came on and the car died, while I was driving. It lost all power and it took everything I had to steer the vehicle off the road. I had my four year old with me that time and was scared I was not going to be able to get us to a safe spot to sit and wait for help. The most recent incident happened last evening on my way home from work. I was driving on the freeway going about 75mph, the warnings flashed and then my car lost power and felt as though it was not handling the road as well as it should. I live in mn and we are in the middle of winter now. I need my car to be safe and I rely on this car to get my son and I to where we need to go safely! this is the only vehicle I have and cannot afford for something to happen to it. I have been reading several forums about others that this is happening to and can't help but feel there has to be something more to the situation. I would feel horrible if something ever happened to my family or anyone else because of my faulty vehicle!! this needs to be figured out and taken care of.

Vehicle was stopped at stoplight. Driver reached down to pick up paper he dropped on the floor, and accidentally got finger caught in lanyard attached to key ring that had the ignition key in it. Ignition switched turned to off, and engine quit. Had to shift to neutral to restart engine.

I drive the car and it says engine power reduced stabilatrak it slows down and it feels forced to drive so I pull to the side of the road wait about 10 to 15 minutes and it starts but then it got to the point were it wasn't even drivable with it stating engine power reduced stabilatrak so I called chevy in modesto CA asked if there was a recall they said no and I told them I seen a lot of complaints on line with the same problems I was going through they said you cant believe everything online miss I took the car into the a mechanic I know he diagnosed it as being a throttle sensor and pedal sensor charged me 587$ I thought the problem was solved a week later it did again engine power reduced but this time it started over heating to ive had nothing but problembs with this car ive also changed the tires numerous times the sensor for tires is always lighthing up and saying check left front tire or back tire I take it to the tire shop they say tires are fine but the back ones need to be changed I change the back tires it still says check back tires ive also had the suspension fixed a few times when itswindy I feel the car moving from side to side I also have had engine problems with the transmission was replaced nowit has has 2 blown head gaskets all in all the past 2 to 3 years I have payed 4 to 6,000 in repair and itsstill running like with it stating engine power reduced stabilatrak I need my vehicleto befixed of this problem.

I was driving down the road and the power reduced, its says reduced power in engine.

Yesterday on my way home from work . . I exit off of 55 onto 1st avenue. Got to odgen avenue and suddenly the car went into a slow motion . Message appeared reduce engine and transaction control. I was not able to go pass 20 miles. I pulled over at a walgreens. Shut off the car and started again. Same message. I finally made it home ( 1-1/2 ), ususally 20-25 minutes. I looked on line last night and saw numerous calls and complaints regarding the same issue. I called GMC this morning and of course no recalls for this problem. . This is a serious issue and I or someone else could have been hurt . .

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.

This is the third time I had to fix this passlock thing on my Impala and im getting so sick and tired of it.

A few months ago, while driving my vehicle the service stabilitrak warning came on and engine power was reduced causing a safety hazard on a busy road. Following instructions from gm, my mechanic cleaned connections on the pedal relay. The same problem occurred this past Saturday while driving on the highway, nearly causing a collision. I have been told the repairs to fix this issue will run close to $1,000. I have also read many forums on the internet indicating this is a consistent problem with Impala's. It is my belief that this should be addressed with a safety recall.

On June 22, 2012 as I was driving approximately 40 mph, the reduced engine power and traction control message popped up on the dash. I know my car slowed down a lot and then picked up speed again. I notice that each time I pressed on the petal to stop at a light or stop sign the car would jerk forward. I did not think too much of it until my husband then drove it and said the same thing happened to him and the car was driving really rough. I did some research and see that lots of chevy owners have been experiencing the same problem. Please enforce a recall as this is not safe especially when you are driving on a freeway.

As I was driving, all of a sudden the service traction control light came on and then engine power reduced light came on. This caused my car to slow down without warning which could have been a dangerous situation had I been on a busy highway which fortunately I wasn't. I read up on this and noticed that this is happening quite often and this should really be remedied before an unfortunate death or injury occurs from this.

I was making a left hand turn. I slowed to turn. A car was coming but far away. The "reduced engine power" light came on and I had minimal power to complete the turn and was nearly struck in the side. I had the decreased power, only after completing my turn did I stop and notice the light had come on. My car has significantly decreased power and acceleration. It is intermittent. I had a very unsafe drive back home. I wish I would have had it towed because it was intermittent decrease of power.

Out of nowhere my door lock actuators for all three passenger doors are not working neither is my trunk opening and to make it worse im sitting in my job parking lot with the a/c on waiting for my break to be over and all of a sudden my car starts blowing air from the outside inside the car and I looked at my dash and my temp level was rising to in between 1/2 and 3/4 got out check coolant coolant was fine and everything else checked fine but now everytime I sit in my car with the engine running and my a/c on it only stays on for about 20 mins, then the a/c cut off, starts blowing hot air, and the a/c nor the recirclation will engage it blinks. And to make it worse I smell fuel on my oil dipstick and my car is drinking fuel like water someone please help me.

On Friday 5/17/2013 I was driving home from work as I usually do and I made a stop at a red light. When the light turned green and I stepped on the gas to drive, I felt the car jerk and then the engine light came on and a message popped up and said engine power reduced. The car struggled to accelerate often feeling like it was going to cut off. I was able to make it to a parking lot where I felt safe in see the car broke down and I turned the car off an sat there for about 10 min and restarted the car. I was able to make it home by taking the highway since that is the only way I can make it home. When I got home the light turned off and I drove the car again and it appears to be driving normal. Then again today 5/19/2013, the same thing happened but this time the engine light did not shut off. I have no choice but to take the highway home and the car was very dangerous to drive because it does not accelerate the way it should. His poses as a danger to my life as well as others. After further research online I discovers that many people with chevy Impalas have reported and complained out the same issue that it can possibly be a sensor in the gas pedal which apparently isn't covered under the warranty and its costly consumers hundreds of dollars to correct. This vehicle definitely needs to be recalled as it is a safety threat.

I have a 2008 chevy Impala. Starting last month (may 2013) the service traction light and reduce engine power lights started coming on. I took it back to the place where I purchased the vehicle and it came back that it was the accelerator pedal. It was replaced and 5 days later the lights were back on again. I called the shop and they told me to bring it back to them on Monday because they were closed Saturday and Sunday. I took the car back to the shop and the lights weren't on. They told me that they could not get a reading on the car and to come pick it up. I drove off the lot and 3 days later the lights were back on. This has happened every week since they replaced the accelerator pedal. When I took it in initially they said it was either the accelerator pedal or the throttle. On Friday June 14th the car stopped the service traction system light, reduced engine power light and starting disabled service/check throttle light came on and the car stopped. It was still running but when I pressed the accelerator pedal it would not move. I cut it off and sat for about 10 minutes. I started it and drove straight to the lot it was Friday at 4:45 pm they closed at 5:00 the guy said bring it back Monday (wow really). I parked the car again all weekend didn't start it until Monday. The lights were off when I got in it on Monday as soon as I backed out of my drive way the lights popped back on and it would only go 40 mph. Luckily the place is about 3 miles from my house when I got there they weren't open yet so I sat there. When they finally opened I drove in and told the guy who I was. The drove the car around several times and could not get the lights to come back on. It is now Tuesday and I still don't have my car back. They say that they took it to the dealership to have them look at it. I'm not sure what to do at this point I need my car to get back and forth to work.

Was driving down the road and out of no where my car flashed a message that said service traction control and then engine power reduced and my car came to an almost complete stop. It would not accelerate at all. This has happened many times now and have caused very dangerous situations while going down the road. The problem will go away after the car has been turned off for a few hours but it will do it again out of no where I have tried to have this fixed multiple times ad there is no fix! it is very dangerous and there should be a recall before someone is killed!.

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.

When my Impala first started to display the engine power reduce message. I was told that it was the accelerator pedal position sensor. So I change the gas pedal the engine light when off for about two weeks. Then my car cut off one day as I was on my way to work. When I went to get it check they told me it might be the alternator and then it was the throttle body. Then there was nothing wrong with it but my car is now park and refuse to stay running. It will start only to cut off a mile or so into driving.

Once my vehicle got near 80k miles, it began to randomly shut down on me as I drive. The message "engine power reduced, service throttle" comes on and I barely have time to pull out of harm's way before the car won't move. This has happened numerous times over the past year--most recently, three times while driving on the freeway and turnpike on Saturday June 28. Driving at 70mph and having my car suddenly lose power is beyond ridiculous. When my mechanic pulls the error code, it's just a general computer error every time. Nothing at all about the throttle has ever shown. Why is this not a recall when you search "impala engine power reduced" and see there are a ton of people with the same issue? does someone have to die before this issue gets fixed?.

While driving, fast or slow, my car will slow down abruptly and a "engine power is reduced" warning comes up on the lcd dash. This has also happened while I've been standing idle at traffic lights. I am afraid that one day my car will stop completely while I'm on the highway, resulting in a crash of some sort.

When taking off from a start the transmission doesn't engage causing the engine to rev, then it slams into gear eventually. Have also noticed a decrease in power somewhat. Have had it in the dealer for service 3 times and of course they say they cant find anything wrong with it. Kinda crappy since the warranty just went out on the drive train about a month ago. Problem only seems to be getting worse. I have read on forums of this issue on numerous vehicles that use the 4t65-hd transmission and that gm refuses to acknowledge that there is a flaw in these transmissions.
