Chevrolet Impala owners have reported 97 problems related to check engine light on (under the engine and engine cooling category).
Car is currently at 134k miles and just gave me a "reduced power engine", "check traction control", and a check engine light. I googled around and came across a lot of chevy Impalas around the same year (07-10) are having the same problem. It seems to be something with the "accelerator pedal positioner pedal sensor. Also reading into it, it claims that this problem can cause the car to suddenly stop from 60mph all the way down to 20 or zero. This is extremely dangerous and needs to be looked into before someone is hurt or killed.

Reduced engine power appeared followed by check traction control. Then symbol for check traction control and engine completely in passing lane on interstate 80. Check engine symbol also lit, car completely died and would not restart. Approx 15 min later, it did start with check engine symbol lighted.
Got a message on my dash a few months ago about "service traction control" while driving. Traction control light lit up also. Parked car and turned car off then on. . . Message gone. Took it into service. . . Showed no error codes. Today (5/2/16), it did it again with the traction control light and the check engine light simultaneously lighting up. "service stabilitrak", service traction control", and "engine power is recuded" are the messages I got today along with the check engine light and the traction control light being on. I had just gotten off the highway so I wasn't going fast when this happened. I was close to work so I parked it at work. Turned the car off then on again and the messages were gone and traction control light was off but check engine light stayed on. Turned car on again at lunch 1. 5 hours later and the check engine light is off now so I doubt anyone will be able to diagnose or fix anything today. Taking it to service to see if it threw any error codes a little later today. I've researched this issue and found that this has happened to a lot of people while on the highway. If it happens to me and I'm in an accident because of this, I will sue the s**t out of gm. I have two small children and if any of us gets hurt or killed, there will be h**l to pay. This issue should absolutely be recalled. It is not due to my key/ignition issue. Already handled that recall. Losing power in the middle of the highway randomly is absolutely dangerous and I'm now very afraid to drive this vehicle. Will never buy another Impala again.

While driving the traction control,stabilizer,engine power warning all come on and the check engine light comes on and sometimes the engine turns off. Pull off road, will not start then minutes later it starts. Check engine light stays on. After multiple starts the check engine light goes out . I have read multiple complaints about this ,yet the nothing is being done. To repair this problem. The effects of this is the same as the ignition turning off. Pending on traffic. This could be deadly. This has happened alot.
4/27 approx 5:20pm @ 70mph, "loss of engine power" and some stabilty warning came on. Check engine light and traction light lit, was in center lane, thankfully got to the left berm. Car would not accelerate. Turned off, touched brake a couple times, sat a few mins, restarted, ck engine light still on, but engine power warning not on, was able to get into moving traffic and took to dealier 4/27 apprx 7pm, with gm rental given to me. As of 1:12pm, no call yet, not sure what the issue is, but could have been fatal!!!! bad, bad bad!!! took a pic, blurry though, frightening! told dealer of sudden surges, but intake rep said it would all be related and didnt write it down.

I begin noticing issues when taking off from a complete stop where the vehicle would lunge forward like it couldn't shift into first gear. I had that checked and nothing showed as an issue, so the mechanic said it had to be electrical. This weekend I am driving it and after 25 minutes in the car the check engine light comes on, as does the notice that my engine power has been reduced, and to service the stability traction control system. I was coming to a stop light when it came on and I pulled off to turn off the car and restart it as that would work when it failed before to reset the system. It didn't reset and I had to drive it with reduced power the rest of the way to my destination. I had this fixed a couple years ago. I did get a notice from gm about the issue and the ability to be reimbursed or getting it fixed if there was a current issue and I was able to get reimbursed for it. Now it is happening again, but my mileage is too high to get it fixed under this repair notice because the letter says that the mileage coverage is only up to 120,000. If this is a known issue and I have already dealt with it before, why should I have to pay for it to continually fail when it has nothing to do with normal wear and tear, which I would have no issue fixing as a part of maintaining the vehicle?! this should be something that gm would fix every time it goes out because it is clear the issue is a malfunction of the overall system and not linked to anything that the driver does or doesn't do to maintain the vehicle properly. In addition what if it has to be replaced multiple times as is the case with mine. I have always been a devoted gm customer, but honestly I am not sure I will ever buy another gm after this issue. It is unsafe and provides anxiety when driving, because it might fail at the worst time and could need fixed again even if I fix it this time.
Service traction control and check engine lights came on this morning. Then a message saying my engine power is reducing. I just bought this car 3 weeks ago. I called gm customer service and they told me there was nothing they could do, even though there was a recall regarding this because it was over the 120000 mile warranty (but I just bought this car 3 weeks ago!!!).

When your at a complete stop vehicle gives a hard jerk like someone has rear ended you. All of the Impala's have a failed transmission pressure control solenoid which can cause accidents when it jerks very hard causing someone to run into the back of another vehicle. No check engine light or anything will come on letting you know the problem. Years 2000 to 2015 all have the same problem. Needs to be recalled before someone seriously gets injured.

I was driving on the highway and all of the sudden check engine light and traction control light come on. Warnings service traction control and reduced engine power are displayed and all but shuts my car off in the middle of the highway causing cars to slam on their brakes and swerve barely missing me. I get over to the side of the road and turn the car off. Then turn the car back on same messages and won't go no where. Do the same thing again only waiting longer and no messages but check engine light still on. I drive home. Next day no warnings or lights. Couple weeks go by does the whole warnings and lights and slows car down again but doesn't completely shut it down. I was in regular street traffic this time about 35mph. And now it's more frequent sometimes a couple times a day to once every day or two. This needs to be looked at. I'm reading about this problem on a lot of Impalas causing major problems and wrecks.
Driving on interstate vehicle suddenly lost all power and would not accelerate & quickly decelerated with any prior warning. 18 wheeler almost rear ended me. Instrument panel displayed “engine power reduced”, “service traction control,” “service stabilitrak”, and “check engine light. ” finally exited interstate safely and shut down engine thinking it was going to blow up and after 2-3 tries to restart messages disappeared and vehicle seemed to be ok. Took vehicle to mechanic & found codes evidencing the loss of communication between the tac and or the app units causing vehicle to go into limp mode but could not get the condition to reoccur. Mechanic had to remove codes to permit to duplicate problem, could not duplicate and told me to wait until reoccurred. While looking for repair shop was scared it would happen again received letter from gm stating if the above condition had occurred they would fix. Called gm dealer mentioned letter they refused to repair unless the messages were present on panel, refused to look at the vehicle. Called gm customer service referencing letter, explained gm dealer refused to repair. Was told by angela issue was safety related problem but gm would not admit to safety issue. Gm agreed to pay for one hour of diagnostic time to determine if vehicle qualified for repair, dealer was unable to duplicate problem, refused to repair. Called gm and was told no repair would be made even though the problem had occurred as stated in the letter and to wait until situation occured again then not to start engine and tow to gm dealer. Was told gm would not pay for tow or inconvenience and if they could see codes they might repair problem. This is definitely a safety issue since when this occurs the vehicle loses all power and basically shuts down and will not accelerate beyond 5 mph if at all. Leo nelson 937-554-9778 noslenlsn@gmail.

I own a 2009 Chevrolet Impala. I was driving on the highway at 65 mph when the check engine light, traction control light and engine power reduced light came on. A few minutes later, in heavy traffic it said engine shutting down and there was a short countdown displayed before the engine died completely. This is very dangerous and I am lucky to have been able to get over to the shoulder without getting hit.

When I was driving to work my car suddenly lost its traction control,the engine went to have power and the check engine light came on. It happens very fast, and now my car wont go over 40 miles per hour. I research on the internet I see lots of people having this problem so I wanted to report it.
Driving 40mph check engine light came on then reduced engine power flashed on message board several seconds later traction control light came on and service traction control came on message board. My speed was reduced to 20mph in traffic! luckily I was able to pull over safely without causing any accidrnt (fyi I had my daughter in thr car with me). I will be taking the car to a chevy shop in the morning where im sure I will have to pay high cost out of pocket even though this has been an issue for chevy owners (online srarch) and there has been many complaints with no recall. This is a serious ussue and I feel it is putting many lives in danger and should have been a recall a long time ago. Im just lucky I wasnt on the highway yet because this could have turned fatal.
Had purchased vehicle from dealer in ashland va back in September 2014. Had no concerns about the vehicle until first trip not driving vehicle for a week and upon return vehicle would not start. Had jumped started vehicle and got check engine light which was on for three days then cut off. In February 2015 had not driven vehicle for two week period and upon return vehicle would not start again. Checked battery and had replaced along with cleaning positive battery post for corrosion. Check engine light was on for two to three days then cut off - check code at firestone dealership showed code p2135 - dealership could not determine where possible power drainage could be coming from and recommended to take vehicle to chevy dealership and have them test for power drainage. As long as the vehicle is started/used without prolonged period of inactivity, vehicle operation for this model year is acceptable.
While driving along a curvy river road my check engine light , my traction control and the stabilize light came out. Then the engine reduced power. Barely made it home. Waited for a few minutes restated the car and it ran normal but still feel the car hesitate. Every time I drive it I worry that its coning to do it again. I live in the part of the county that gets snow and am worried its going to happen durning a storm, this needs to be addressed.
