Failure Date: 02/22/2018

Engine suddenly died while I was driving. I pulled over to the side of the road and it almost caused an accident because power steering went out. I was able to start the engine back up no problem. I had a check engine light on because of the oil pressure sensor. I had just replaced it the day before. I suspect it had something to do with that, but im not sure. If I was on the highway im pretty sure I would have gotten in an accident. This isnt the first time this car has almost caused an accident because of faulty car parts, this car is dangerous.

On two different occasions, once about a year ago and again today, my 2011 chev Impala ltz displayed a series of rotating alert messages -- 1. Service traction control 2. Service stabilitrak 3. Engine power is reduced. I was driving about 45 miles per hour on an open road when all of a sudden the engine started running very roughly and slowed down and the above 3 messages repeatedly displayed one after the other. Also 2 yellow lights were flashing and then remained on -- the check engine light and the traction control light (I think). When I reported this problem to the chev dealership a year ago, I was told that because the warning lights and messages could not be reproduced in the service department, there was nothing that they could do. (and I understand that if it isn't broken when I take it in, the service dept would most challenged to fix it. ) today, when this happened I was able to get the car to a safe place to park. I turned off the ignition, waited a moment and then restarted the car. The same 3 messages were displayed with the two yellow lights staying on. When I restarted the car 3 or 4 hours later, only the check engine light is displayed. The 3 referenced alerts were not displayed. I am getting ready to take the car to the dealership again with this problem. Do you have any advice as to how to proceed?.

While the vehicle was in motion on dry pavement, the traction control light came on, followed by the check engine light then the car stalled and had to be be eased off the highway. Tried to restart the vehicle several times. After it sat for a couple of minutes tried one more time and the car restarted and drove home perfectly. Researched the issue online, and there are entire forums in edmunds dedicated to this very problem. Definitely a safety issue with this vehicle.

When taking left turns the car makes a loud grind noise then the stability controll will turn on. Now the check engine light and stability controll light popped on while driving while also having engine power reduced which then applied my brakes causing me to almost go off the road.

Vehicle was in motion in the middle of a very busy intersection, thank god it was at night. The car started violently shaking and the display put up the warning "low engine power" and "service traction control". Has happened numerous times before when the car was parked but never while driving. Check engine light comes on for a little bit but then usually goes away after a day or so.

While driving the traction control light came on as well as the check engine light then reduced power so that I was driving at about 5 miles in traffic. Car then stopped and there was no power at all. I put on my hazard lights and turned the car off waited a few minutes and it started and only check engine light remained on. I was fortunate to be almost at a red light when this happened in midtown manhattan so that there was only blaring horns when I couldn't move the car. My mechanic said I need to bring the car in when the lights are on so that he can read the error messages. The check engine light doesn't give him enough information. I haven't driven since as I'm afraid but will drive locally and bring the car to the mechanic as soon as those lights come on again. It has happened before but not when I could bring it to the mechanic.

For the last two days, I have driven my vehicle. Every time I would drive over 40 mph, the engine would lock up. The vehicle would jerk and shake back and forth. The car would do this every time I went over 40 mph, no matter if I was driving on a highway or road or coming to a stop at a red traffic light. Whenever this happened, the check engine light and the traction control light would stay on. This problem started weeks after I had an auto accident.

For the last two days, I have driven my vehicle. Every time I would drive over 40 mph, the engine would lock up. The vehicle would jerk back and forth. The car would do this every time I would try and drive over 40 mph, no matter the roadway or stop at an intersection. Whenever this happened, the check engine light would stay on. A month before this problem started, my father had been driving the car and had an auto accident.

Failure Date: 01/06/2017

I would like to place a complaint about my 2016 chevy Impala ltz that I purchased from car max in glencoe, IL on November 11 2016. I am a frequent traveler to central michigan and on my return trip to chicago on January 6, 2017, I was traveling south on highway 127 just south of mt. Pleasant michigan when all of sudden, the car lost power and it slowed down rapidly, there was a car behind me who almost rear-ended me, my wife and I were terrified. I pulled over to the side of the highway and put on my flashers. I looked at the dash and the following error lights were on (service engine soon, check engine light, reduced engine power, and stablitrack light). I looked at the owner�s manual and it suggested that I turn the vehicle off and that it would reset. I followed instructions, turned on vehicle and all lights were cleared except check engine light. I got back on the highway and started to drive towards graff Chevrolet in mt. Pleasant. In route, it happened again. Car lost power again, and all previous lights returned. I somehow made it to the dealership. Please see attached invoice, customer number 213805 for work done. From what I see, all that was done was all codes were cleared. I did some research on the internet and it seems to have happened to other chevy owners. I think that it�s extremely dangerous and my wife and I now literally afraid to drive this car. What is being done to address this problem, in my opinion, these types of errors should not be happening to a one year old car.

While driving my Impala, with no warning, my car lost power. The dash beeped at me and said reduced engine power, service stalinktrak, service traction control. I had to turn my car off, I waited a few minutes then turned car back on. The car was able to run and drive after this, but my check engine light was on. I had vehicle computer scanned and had a code for throttle position sensor. After further research, I have learned I will need to replace the whole throttle body. My car has now lost power several times and my rpm gauge 'bounces'. I will be parking my car until the part comes in. This was very dangerous as you lose all power with no warning going down the expressway.

My car's engine power was severely reduced suddenly when I was driving on interstate highway 275 north in tampa, FL. A message showed on the dash: " reduced engine power, service traction control" and the check engine light was on. This happened today around 7 pm on oct 30, 2016. My car is a chevy Impala 2009. I searched online and found thousands of messages about the same error message of reduced engine power on many models of gm cars including Impala, malibu, trailblazer, silverado. This worries me very much as so many same error messages and engine problems happened on so many gm cars. My research shows that gm has done nothing to resolve this problem yet. So this irresponsibility of gm on this specific issue put the lives of hundreds of thousands of drivers in danger. I hope NHTSA looks into this problem and pressure gm to issue a recall if possible to take care of this serious problem. Thank you!.

The check engine light comes on and it says service stabilitrak reduced power engine. Then the car slows, it may jerk, or stall. This has been an ongoing issue. I've taken it to be looked at least 2 or 3 times. I've been told they don't see anything and I should bring the car in to get serviced the light comes on. It usually last a few days but it will come back on. I've also received a letter from Chevrolet about fixing it but when I took it to get serviced I was told that it had to be under a certain amount of miles. This is a safety hazard and could cause a potential car accident or even death if traveling at high speeds and then all of a sudden your car engine reduces power. I know this because I've almost been in an accident twice due to this issue.

Major safety issue! while driving on the expressway hours from home reduced engine power/service traction control/check engine lights came on. Cruise control disabled as well. Car stopped on the expressway, steering wheel locked up. Luckily we were able to coast to the side otherwise this could have been a disaster! vehicle was towed to a nearby service station where it is currently located. There are several complaints out there like this. Gm needs to recall and fix this problem!.

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.

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.

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!!!).
