While driving 65mph vehicle just died. Was not able to start for about 15 mins. This has happened several times nearly causing several accidents. The vehicle intermittently has reduced engine power while driving and jerks from a complete stop sometimes. Now the oil engine pressure/turn off engine light and alarm go off all the time. Replace the sensor, but to no avail. The loud knocking sound from the dash is utterly annoying. I think the fact that only the police cars got recalled is insane, no matter what the recall was. I'm sure once they took those vehicles in; all the other issues I have mentioned were also fixed. Also the rear driver side power lock is faulty and unsafe when traveling with young children. I honestly believe with so many consumers having the exact same problems, GM should issue a recall on these vehicles before several tragedies occur and we then just become statistics. Please help. There are so many of us out here with the exact same issues on these Impala who should not have to pay for the repair of something that apparently should be recalled by GM. Thank you for your attention to this matter. Updated 2/18/2015

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 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 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.

Service traction control/engine power reduced lights came on dash. Car lost all power and when stomping the gas pedal speed would resume, very hesitant from a dead stop. Car was jerking, shut off traction control and car jerked then too. GM needs to fix this before there are deaths. Also I have no unlocking doors. They have to all be manually unlocked. Battery was replaced in car and on key fab. Gas pedal sensor and throttle body sensor are the triggered codes, GM needs to find the real solution as these don't seem to fix problem.

I was at a stop sign, when I went to pull onto the highway, the transmission slipped and hesitated! I took it to GM dealer and was told they could find no problem with it! it would actually have to go bad before they could do anything about it! now I have 68000 miles on it, and the problem happens daily! two days ago, when pulling on to the highway, it hesitated again, but this time there was a semi coming! luckily it finally took hold and I could proceed! I saw on the internet, that this is a common problem for this vehicle!! why, doesn't GM fix it?? also, I have had my car in for engine problems, they have removed the engine from the car, and "decarboned the cylinder"! now about 30000 miles later it has the same problem again!

Our 2008 Impala ls, with 100,000 miles, is having the same problem I am seeing at this web site and all across the internet. Last month, may, 2014, and this month, June, 2014, there was a sudden reduced power alert on the dashboard and the check engine light came on. The speed immediately dropped to no more than 35 mph. Before I could get it to advance to have them check to see if any codes had been dropped by the computer, the check engine light went off. There was no reduced power message either, and the speed returned to normal. I was told to try fuel injector cleaner, which I did. All went well for almost a month, when the same thing happened again this month. This time I was able to get it to advance with the check engine light still on. The computer had dropped 2 codes, both related to the accelerator pedal position sensor. Advance did not have the part, nor did autozone. Fortunately, Napa did, for $90, including tax. Our local Chevy dealership wanted $50 more. Since it is a very easy part to replace even for an amateur like me, I replaced it. There are only 2 10 mm bolts to remove and an electrical connection to unplug. So it was pretty simple, and so far, this has done the trick, but it's only been 24 hours. This apparently is a job that the dealerships want to charge $300 to $400 to do. As I said, this is a widespread problem for GM, and they have not and will not, so far, do a recall. They should. I'm only out $90 so far, but other people are out much more. If I have the dreaded, follow-up problem with the throttle body, I will be out a whole lot more. I sent an E-mail to Chevrolet after the first instance, and did get a response back. I told him I didn't want to take any further action unless this happens again. I will be contacting him again now about this latest incident.

Frequently, service traction control and engine power is reduced lights come on. When this happens, car is sluggish and will not accelerate. This is very dangerous because it happens unexpectedly and causes vehicle to decelerate quickly. Typically the car will start normally after sitting for 15-30 minutes but check engine light remains on for some time. Also, the message engine hot/ac off fires randomly. Temperature gauge rests at zero. It will start working again either through manual reset by removing battery cables and reconnecting or randomly start working again on its own. There are numerous reports of both issues on the internet which indicate replacement of sensors/throttle are very expensive and do not fix the issues.

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 essentially unable to trust our vehicle beyond about 50 miles per hour.

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.

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.
