The welds to the bracket that holds the control arm broke, if it broke while on highway that would have been deadly.....

- service stabilitrak. A reduced power light usually indicates a fairly serious problem with the throttle system. When this light illuminates the vehicle will often go into a 'safe mode', which will severely limit the speed of the car and in some cases will render the vehicle un-drivable.

There's lots of static and I get shocked all the time which shutting my vehicle off or starting. I have had no off market work done to my vehile so its all as it was when original purchased.

I was driving my car and suddenly it flashed across the screen service stabilitrak, then service traction control system, then reduced engine speed. This caused my vehicle to slow way down out of no where from 70 to less than 30, and made steering near impossible. I have my two children I drove around and I'm afraid to even drive because if there's an accident with them in the car because my cars slowing unexpectedly someone will be paying for this. This is a huge safety issue and I see all over it is and it needs to be fixed!

I have been having problems off an on with several issues I don't know if it's sensor, wiring, wheel, or other related but I have been having issues with service stabil trak, service airbags, traction control, braking related, etc. Most recent has been with service stabil trak. I took to dealership and they said computer showed throttle body needed replaced and I've done that then a couple weeks later same lights coming on only this time dealership says it's the right wheel speed sensor harness but I didn't have that repaired because I am seeing in forums online others having same issues and it's an ongoing problem no matter what part of the system you fix so I've been turning off traction control so I don't get warning lights. Vehicle always in motion with these problems and after all the issues I've had and still have I know now that an accident that happened about a year ago is definitely related to all this. I was approaching a busy intersection and saw light was yellow so I started slowing down and came to a complete stop I remember having my foot on brake pedal and next thing I knew my car had slammed into the rear of the car in front of me it happened so fast I was stunned and couldn't comprehend what had just happened and the person I hit was a pregnant female who was very upset. I told her I had no idea how the incident could've happened with my foot on brake we were both on our way to work and since there was no real physical damage to our vehicles we just exchanged info and headed to work. I know now it was related to this somehow and wished I would've reported it. The car had accelerated on its own!! I bought this car from the dealership with 41,000 miles (highway miles ) I was told it now has 92,000 miles on it and I have done all the oil changes and required maintenance but have spent several thousand hours at dealership with every issue imaginable.

Door system on the car has failed multiple times where I have to take the door apart and fix it. It's not all 3 doors it's just one door. I understand you may not think this is a safety thing. But I'm a firefighter and let me tell you that if I had someone in the back seat and I get in a crash. How are they suppose to get out? since I have a car seat on the other side. Especially if the car catches fire. I guess someone dying will have to changed that.

I think there should be a recall on the stabilizer bar. Our engine powers down if the wire behind the gas pedal gets loose. This has happen to my husband car more than once driving down the road.

I left work to go pick up my daughter at the airport (about an hour away) but heard dinging and saw that I was getting the message to service stabilitrak/traction control and that engine power is reduced. Luckily I was not on a highway at the time, but I would have been if it had happened while I was picking up my daughter. I drove straight home instead and my husband had to leave work to pick up our daughter. I am taking the car to the dealer next week for service. It appears that this is a very common issue with this model and needs to be addressed by GM.

I was driving on I-695 (in baltimore) with my 3 daughters I received "service stabilitrak, traction control, engine power reduced" message while driving around 65 mph. The engine and tracking light came on and the messages would not go away. I was frighten and hopeful that we would not only make it to our destination but then back home again. Fortunately we did but the very next day I have researched this issue. It seems to be a ongoing issues and maybe cost me hundreds of dollars to repair. That makes me nervous because I am a single mother with only one source of income.

While accelerating, at approximately 45 mph, the acceleration pedal became stuck and the car would not stop. Brakes were applies and engine fought the brakes until I could get the car stopped. Engine continued to rev high and I called 911. Police dispatcher advised to turn off car in drive. Police arrived and saw that there was no floor mats over the pedals. A few moments later, police and I heard a snap under the dash. At that time we had no idea what the sound was. I subsequent started the car and it idled perfectly. I later figured that the snap sound was the accelerator pedal returning to the outward position. Very scary experience that almost caused several accidents, during the ordeal.

After starting the my Chevy Impala the engine started shaking rapidly. It showed service stabiltrak, low engine power & the check engine light came on. I shut the car off & started it again. It did the same thing. I cut it off but it did the same thing. I cut it off 1 more time because I did not feel safe driving it & waited a minute before trying to start it again. Surprisingly the engine was running rough. I took it to an auto store where the codes showed throttle issues. I took it to a mechanic. He did some additional tests & informed me that I had a bad throttle body. I had to have this replaced which I was informed that GM has had issues with throttle body & components. Very disappointed that this would happen. Im concerned that this might happen again or happen during driving.

Relay switch on driver side for air conditioner clicks for several minutes and blows hot air. The passenger side currently blows cold but now the clicking has been happening there also. I had a total stranger hear the noise while I was pumping gas who said his Impala did the same thing. This is obviously a common defect in Chevrolet Impala that should be taken care of. This happens everywhere all the time moving and parked
