2010 Chevrolet Impala: check engine light

Filed Oct 18, 2024 · Acceleration, Engine · MO

I started my vehicle in the morning to let it warm up. I come back out to get myself and my son in the vehicle to go to work and take him to school. My dash upon entry had a check engine light on, and the message it displayed was "engine power reduced." I put my car into reverse, having no choice but to drive it and the traction control went out. My father in law pulled the code and it said something about the accelerator sensor. This is a known issue and recall in other models and I wanted to report it is also happening in my model.

My car has worked fine scince I bought it with no check engine codes.I pulled into parking space and put car in park,all of a sudden it stalled out and will not crank anymore but has power.key will not come out of ignition and battery will not shut off.the ignition switch is a very common problem with impalas and is very dangerous.it locks people out of there cars,gets stuck in gears,wont let key release,wont start,sets off anti theft signal which cuts power to door locks,trunk,starter,fuelpump,and more.I have read hundreds of forums of this problem with chevy impala that has been going on for years without the problem being fixed.elderly women breaking down on highway or car just shutting off and not restarting.it is soooooo common with chevy that they can diagnose the problem just over the phone.this is very unacceptable and has to be dealt with.please recall this problem.

Driving uphill & the service stabiltrak & the serice traction control words came on followed by reduce of engine power & the service engine light & traction control light came on. We could still drive at about 20 MPH uphill & 45-50 on flat roads. We shut the car off 4 about 2 hrs 2 cool down. But then as soon as we headed up a hill it started all over.

I was sitting in the parking lot with my engine running for about 10 mind. All a sudden 'reduced engine power' came across my dash and my service engine light came on. I turned my car off. About an hour later I turned it back on and the message was gone. Then as I was driving down the road my service air bag light came on. It only comes on when the passenger seat beat is clicked on. And my driver side back door auto lock stopped working.

My chevy impala when in motion has signals for service stabilitrac, the check engine comes on and the a message that says reduced engine power shows up. It seems like alot of impala owners are experiencing this and something should be done! The stabilitack goes off and the check engine ligts stays on but usually goes off, and then a few days later it will happen again.

Air bag sensor has been tripped for the past 7 months, I have researched this recall, and it looks like the wiring harness might be the only thing that needs to be replaced. However, whenever, I put in my VIN number, there aren't any recalls for this. Also, I have received a letter about the gas sensor possibly being bad, however, when I took it into a chevy dealer to have it fixed, they refused to. They told me that the check engine light wasn't on, and that I had to wait until it failed before they would fix it! Failure of this sensor means, it could fail in an intersection, or while I am passing someone, or whatever, this is a safety concern!!! I am very unhappy that they wouldn't fix it. Now, my check engine light is on, however, it is because another sensor is bad! The evc sensor now has to be fixed. The airbag sensor was tripped while I was driving on the hwy at 70 MPH on a warm day of 80 f or so. The evc sensor tripped overnight when I started the car in the morning. The gas pedal sensor has been a problem for 3 years because chevy dealers refuse to fix it. These concerns are in addition to the other mechanical fixes that I have had to do on a car that has less than 87,000 miles on it! I am feeling like I have a lemon of a car and that this impala is the worst car on the market. I have had several chevy products, and have never experienced problems like this. What happened to the great products that chevy once produced???

Driving home one night after just having my vehicle repaired a few weeks earlier, without warning, my vehicle began to stall. Just before the stall it was driving completely normal with no issues at all. Suddenly the check engine light came on along with the messages of service stabiltrack, traction control disabled, and low engine power. When I took the vehicle to the dealer I bought it from I was told that there was an aftermarket senondary air check valve that was causing the issue. With this they gave me the following codes; p0068, p0340, p0651, and p2135. Due to me just recently getting this part replaced this past february I took it back to the mechanic that replaced it. When I received the vehicle back it would no longer even start. The mechanic then informed me that the air valve would not cause this issue and there was something else wrong with the vehicle and to take it to another dealer. When that was done I was told a second time that it was the air valve. I have now come out of pocket twice for tows that I can't afford. Along with paying for an expensive part possibly twice. Vehicle only has 50k miles on it and has never given me any issues until this year.

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.

Reduced engine power lights came, on traction control light came, on it was hard to accelerate in the middle of a highway, car almost shut down, but I made it home. It has happened twice on the highway and turnpike. I thought it was oil but that wasn't the issue. It stops (the problems) after I shut the car off for an evening, but I'm scared it will power down while on the highway again. When this issue happens the car beeps, then the traction light comes on with warning and so does the engine light and reduced engine power warning. Always in motion, especially higher speeds than normal city streets. Such as turnpike and highway.
