On 4/28/13, while turning into church parking lot, traction control and check engine lights came on. Computer check the next day showed code 2127. The computer was cleared and this problem code did not reappear. On 5/28/13, while driving on a flat country road at about 50 MPH, traction control and check engine lights again came on. I had to drive approx. 20 miles to get back to my mechanic. Part of the computer response during the this time was to reduce engine power. This was noticeable on any minor hill. Again, my mechanic checked the computer diagnostic and said code 2127. I took my car to my dealer 5/29/13 and they replaced the accelerator pedal assembly.
2008 Chevrolet Impala engine complaints
Page 6 of 6: complaints 131 to 160 of 160, newest first, as owners wrote them.
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 was driving my sales route and over a few days time, my car would have the engine picture lit and a message of reduced power would appear and I could not drive any faster than 50 and my foot was to the floorboard. This was very scary in that if you are on the highway the cars behind you do not know you are having a problem before you are able to exit off. Even starting from a stop light is dangerous because you can't get your speed up very fast. There were a few times where the car lost total power and I had to coast over to the side of the road. After letting the car sit for a few minutes, it started again but still had the engine icon lit and he same message appeared. I did have a part replaced at my expense of $200+ and for a very short time it did fix the problem but then very shortly it started doing it again. I was laid off my job so was not doing the route sales any longer and was using the car just for personal running so didn't pay to much attention to getting it looked at and my wife had her car to use for trips. It recently has been to where the light and message will not go off and it is constantly in the reduced power made. This is a very dangerous situation and due to the number of complaints this must be taken care of. I did take it to the chevy dealership this week to see if I had missed a recall. The mechanic was well aware of the problem and said there was a recall for trucks not cars and he did not understand that. Nor do we. Now if you know this is a potential and is very common on these cars as we are told, then it needs fixed now. Fixing this, since you know the severity and possible problems would sure be better than a lawsuit I would think. I await your timely response. I will kick this up higher but wanted to start here. Compensation is due on this matter. I have my receipts.
My wife and I purchased the chevy impala to be our first vehicle together after getting married. Bought this vehicle brand new only 102 miles on it before we drove it off the lot. Little did we know it was going to be 4 years of nightmares and headaches. At the time read many review about the impala, nothing too major was found. After the first week, the power steering seemed to be failing, especially during rain. Took it back to the dealer and they could not replicate the incident. They told us they could not find anything wrong and to bring it back if the problem continued. It didn't take long and we were back at the dealer with the same problem. Dealer said they checked the belts and the fluid all working properly. After a few other times of the power steering failing took the vehicle to another dealer and they too could not find anything wrong with the ps. So, after several trips back to dealer we decided to just deal with it. Which brings me to my next complaint about the 2008 impala, at just over 10,000 noted abnormal wear on tires, and wires peeking through on the inside. Took it in to dealer and they accused us of abusive driving behavior and neglect, which was a new on to me. Anyway, they refused to replace the tires sitting the warranty only covers defects and normal driving conditions. So, by this time we are starting to regret the purchase of this vehicle. We had to replace all 4 tires @ 98.00 each. About year later at 28,000 miles began to have this problem once again. After many hours of debates and phone calls they agree to "check out our problem" with no cost to us. Low and behold wouldn't you know it, they found nothing wrong with the vehicle and advised us to purchase better brand tires. The last time I looked michelin was a top brand tire. On top of everything else, main seal in motor began to leak. This was the last straw!
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 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.
Tl* the contact owns a 2008 chevrolet impala. The contact stated that while driving at various speeds, the driver noticed a warning that stated engine power reduced. The vehicle was taken to the dealer. After inspection, they advised her that they were unable to diagnose the failure. The manufacturer was contacted and they offered no assistance. The failure mileage was approximately 98,000. The current mileage was approximately 105,000. The VIN was unavailable.
Tl* the contact owns a 2008 chevrolet impala ss. The contact stated that while driving at various speeds, he noticed a warning that stated engine power reduced. Immediately after, the vehicle decelerated. The vehicle was later taken to dealer. After inspection, they advised him that they were unable to diagnose the failure. The vehicle was not repaired. The manufacturer was contacted and they offered no assistance. The failure mileage was approximately 75,000. The current mileage was approximately 75,500.
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 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.
Excessive wear on my rear tires. I have been told that the suspension is faulty and that excessive repair work had to be done to remedy this. I had to call aaa on one occassion because one of my rear tires blew out because of this problem. No injuries and I was lucky that I was driving in the city when this happened. On the highway, I could have cause great damage to myself and possibly to others around me. My car burns thru oil so super fast. It burns a quart of oil approximately every 750 miles.
I was starting the car up and the engine was going in and out. I noticed that the check engine light was on and it stayed on. The stabili-trac light also came on. The panel also said that the engine was losing power. This happened 2 times within the last 8 days. I stopped the vehicle and turned it off. Cranked it back up and the check engine light was still on. Took it to the car dealer and they said that it was the throttle position sensor.
Check engine light comes on due to constant sensor failures. The first was a faulty oil sensor. The car shut down and was unable to start or run do to a service stabilitrak code. Because of theboth issues we were unable to properly secure the car and its contents. The breakdown also cause us to be stranded in extremely cold weather.
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.
After mysterious loss of coolant, the head gaskets required replacement due to bad head bolts from the factory. This occurred 2 months after the factory warranty expired.
Reduce power light comes on. Cars speed drastically reduces. If you pull over and wait for about ten minutes and restart the car,it resets itself.
I was traveling on a highway near to my home, and for about a month now the vehicle has come up with an error stating "reduced engine power". Suddenly, the vehicle simply stalled itself, coming up with a message that stated "starting disabled/service throttle". I was traveling uphill at 40mph, now with no power brakes, no power steering, and the engine completely shut off and unable to restart. Luckily I was able to pull over and disconnect the battery and reconnect it to restart it. What if this had happened on a highway on or off ramp? Or on a corner? Or with a vehicle traveling behind me? I believe any vehicle that will just randomly turn itself off due to a part that has had hundreds of complaints that I've just read online is unsafe to be driven on america's highways. I read online that this was a prevalent problem with these vehicles, and I hope I get injured because of it so I can sue gm.
On 10/5/11 I tried my 08 impala for first time in rain since I purchased it used 4 months earlier, the car is a police version with the 3.9 flex fuel engine. Was excited to try out new tires in rain . , I went thru a few puddles it seemed ok,it wasn't even raining hard, when a car stopped in front of me, I also stopped when I tried to turn left to go around the car the steering wheel just froze,I had only driven about 1 mile .after few seconds it was ok, about 1 minute later it did it again. I just drove it back home disappointed knowing I wont be able to drive it during raining periods . Found out thru internet that many customers having same problems with this car . Gm needs to recall this car before someone gets really hurt driving this dangerous vehicle ! Hopefully not to late!!!!!! Was lucky this problem was discovered while car was stopped and not on highway.. Checked fluid, belts, all good . . From los angeles
Tl*the contact owns a 2008 chevrolet impala. While driving approximately 30 MPH over a small bump in the road, the vehicle stalled. The contact was able to drive onto the emergency lane and restart the vehicle. The contact was able to drive the vehicle without the failure recurring. The vehicle was taken to the dealer where the technicians could not diagnose the failure. The failure occurred three times intermittently. The manufacturer was contacted and researched the failure. A district manager returned the contacts call and stated that the failure could not be duplicated or diagnosed; yet, they did not provide assistance. The approximate failure mileage was 38,048.
While driving at highway speeds, the check engine light came on, then the service traction control devices came on and immediately afterwards, there was a reduction in engine power and the car slowed considerably. The vehicle was taken to a dealership and was diagnosed with a failed throttle body. The throttle body was replaced and there has been no problems since. The failure was at 51757 miles and was not covered under warranty resulting in a $400 bill that the manufacturer would not cover.
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.
Tl* the contact owns a 2008 chevrolet impala. While the contact was driving approximately 25 MPH , she began reducing speed as she approached a stop signal. The "check traction control" and the check engine warning light indicators illuminated on the instrument panel. The contact stated there was a significant reduction in the engine power to the point of almost stalling. The vehicle was taken to an authorized dealer where the contact was informed that the failure was contributed to the ads sensor. The vehicle was not repaired. The failure had continued to occur. The vehicle was taken a second time to the dealer where the technician performed a diagnostic testing which indicated that the failure was related to the wiring harness and not the ads sensor. The vehicle had not been repaired at the time of the complaint. The failure mileage was 54,000. Updated 8/2/10 *cn the consumer also stated the rear door lock didn't work. Updated 08/09/10
I own a 2008 with less than 50,000 miles on it and the check engine light came on. I had it diagnosed and was told it is the secondary air injection system (diagnostic trouble code p2444) which caused the vehicle to fail the emissions test. The dealership refuses to repair it and states the warranty is only valid for 3 years or 30,000 miles. I cannot get the vehicle inspected until the problem is fixed and the check engine light goes off. I am very disappointed that a car only 2 years old can have such a major problem in such a short amount of time. The repairs will cost $1600 to $2000 because it is an internal problem with the engine. I tried to get the code reset only to have the check engine light come back on.
Hit a deer on the right passenger fender and the car shut down, steering wheel locked, spun and unable to control car, was unable to move car, stalled on highway for 1 hour. Car engine started but unable to move. Almost hit a truck in the opposite direction, due to inability to stop and use steering wheel.
The vehicle made a loud screeching noise. I can't remember if I touched anything,but the vehicle stalled while in motion. I put the car in park, and was able to restart with no problems. I then drove slowly and turned on the air; when I changed the flow of the air to flow from within the car, it made the screeching noise and stalled again. Restarted the car, turned on the air and it stalled again. I took it to the chevrolet dealership and they said that the AC compressor had failed and was tearing up the engine belt, which would also have to be replaced. With parts and labor, I was quoted $1200.
My vehicle I purchases fro the dealer was supposedly in excellent shape. Not until I moved to los angeles, ca. I realized that the engine was not performing correctly. The engine is to drop down from a 8cycl to a 6cycl when it is in overdrive (60+MPH). (this is called 'active fuel management system.) my engine would not due that. I took it to several dealers but they refused to fix the problem. Dealer said "it wasn't their fault. We bought this car from an auction". I feel their was something wrong with the car. Dealer inspection checklist was dated 3/26/2008. The car was a rental vehicle prior to me purchasing it as a used vehicle. The odometer reading was 12410 on 5/17/2008. I feel their was a problem with the engine "safety".
Our company owns a 2008 chevy impala that will shut off for no reason. Sometimes, after the driver puts the car into 'drive' or 'reverse' from park the engine rpms surge, the radio gets louder and the car shuts off. It has surged and then died while going down the road at 50+ miles per hour. It has died while in drive but stopped a stop light/sign. The driver has to put the car back into park and the car starts. This has happened numerous times and the local dealership has not been able to fix it. It is a serious hazard.
When accelerating or decelerating, the vehicle will stall. This happens 1-2 times a week. The consequences are that I am left in the middle of traffic with a suddenly inoperative vehicle. I have had a stall out while making a left turn at a traffic signal. I have had a stall out while merging onto a freeway!! Most recently I had a stall out that required immediate recovery and evasive action while making a left turn which resulted in a flat tire. I have to put the car in neutral and restart immediately to avoid a possible collision. I have been very fortunate so far. The dealership service department was unable to duplicate the problem (because it is intermittent) and there was no code showing. They told me there is nothing they can do to assist me and were rude and discourteous and implied that there really wasn't a problem with the vehicle that I was just trying to get a free replacement tire. The dealership is sundance chevrolet in grand ledge mi.
The contact owns a 2008 chevrolet impala. The contact states that she drives the vehicle and the vehicle starts to shake and when she gives it gas it cuts off. The contact also states that when the vehicle is parked and turne off the contact tries to turn the vehicle on and it does not come back on. The contact also states that the vehicle was towed to the dealership. The failure mileage andcurrent mileage was 29511.
I was driving through a low area in the street that had a puddle of water to drive through. I was going to turn right and the steering wheel would not turn and then all at once it did turn. I did not have any more water to run through until about a month later in a hard rain and it did it again. This was also when I wanted to make a right turn. This all happened in lakeland fl. I contacted bill heard chevrolet in plant city fl and made an appointment. They checked it out and said they could not make it do that but they ordered parts ( a new belt) and installed a few days later. Another rain storm and it did the same thing only this time the instrument panel lights all come on for about a 1/2 minute. I reported this to the dealer and they said bring it back in a they would check out and replace the tensioner. I was driving back to michigan and I was at the georgia and tennessee state line in a rainstorm and it locked up again. I contacted cliff anschuetz in alpena mi and made an appointment with them. They checked it out, put water on the belt but said they could not make it happen. Another service rep said he would take a look at it and put on a new belt and tensioner and they did. The belt always squeals when you first start up in the morning. It still does that and I have no doubt the power steering will lock up when it rains. First incident date was sometime in march and to date. This is a very dangerous problem.
