Warning says engine power down. Gm dealer said recall expired for throttle/pedal position sensor. My vehicle is under 100,000 miles I never received a notice of this recall. I would like to have it fixed under recall.

Power reduces in heavy traffic. If I slow because of traffic it jerks like brakes are still engaged. Acts like transmission going out. This can cause someone to get run into from behind. There was a recall earlier this year. The mileage was not enough to cover my vechile. There should be no mileage limit.

I bought this car from the car lot and the sensors keep going off, the seat belt doesn't lock up, sometimes it says engine is hot turn of AC when it isn't on. And when turning it's will sometimes make a vibrating noise that won't allow me to go then the accelerator kicks back in to go.

While driving, the car in motion it completely loses power. Have experienced this while on highway, interstate, and in town roads. So problem occurs at any speed, and results in vehicle coasting to a stop as the steering and brakes stop working too. Has happened to me hundreds of times as we can not pin point problem, and has replaced numerous different parts trying to solve it. When power loss occurs there is very little to no time at all for driver to coast & steer vehicle & occupants to safety area on side of road. The dashboard information center will state "starting disabled, service throttle" also engine power reduced" and "service stablitrak." a new throttle has been put in vehicle and still does same thing. Over the year ive been dealing with this issue ive noticed it does it more in warm weather. After vehicle coast to a stop and is put in park and turned off, wait 5 to 10 minutes then vehicle will start up and no information or lights display in dash center, like it never happened.

Reaccuring problem with grinding on front wheels with traction control and ABS lighting on control panel. Have had wheel hubs replaced which had no effect on the problem. The car feels unsafe to drive. Have read many complaints of other impala owners with the exact same problem. The grinding occurs during acceleration when moving forward or backward mostly when turning but has occured when just moving forward, mostly on city and suburban streets. The problem developed about 5 months ago and continues to date. Need help and advice please.

The service air bag light keeps coming on while we are driving our car. And I'm worried that the air bags will not deploy in a accident, or they may deploy while driving down the road. I don't want to disable the air bags but not knowing why the light for the air bags is coming on. I have looked online to see what I can do about this and I have found out that this is happening a lot on the 2006-2014 impala's. And people have taken there car in to the dealership to get fixed and the dealership can't figure out why this is happening. And they can't seem to fix it. Plus our service our traction control keeps coming on and the dealership can't figure out why this is happening. This seems to be the problem with this car and the dealership can't figure out why this is happening so they can't fix it. So I'm worried that this car isn't safe to drive because the air bags might not deploy in a accident or if they will just deploy driving down the road.

While driving on roads and interstates, I frequently receive a dash notification "engine power reduced" and my service traction control and check engine light comes on. When this happens, my vehicle loses speed and cannot accelerate above 40mph - dangerous, especially on an interstate. The notification lights and symptoms occasionally go away after turning the engine off and on, only to come back later. I cannot find and answer to this problem.

Abs and traction control lights intermittently come on causing car to jerk with acceleration, or occasionally, to slip during braking. Wheel hub assemblies have been replaced multiple times and the same faulty issue keeps reoccurring. Low quality wiring and position and tautness going into the harness are a recipe for disaster. Sensors can be set off with as little effort as gently rocking the car, definitely going off if there are any bumps or potholes in the road. Also had other annoying although less dangerous issues: door lock actuators and heating/AC actuator, causing door locks to not respond and causing a horrible clicking noise in the car, respectively. I have walked away from the car thinking I had locked it only to find one or more of the doors did not lock. Actually had items taken from the car. The clicking noise from under the dash was sporadic, usually upon starting the car, but occasionally while driving with no notice. This ear splitting, headache inducing noise would for the most part stop after several minutes of driving, but would sometimes continue after the car was shut off and would drain the battery. The electrical system throughout the car is horrible.

The impala displays service traction control followed by engine power reduced. Throws a code for throttle body sensor, but that does not fix the issue. Accelerator pedal position sensor is another reason they say, which also does not fix the issue. My car has shut off on me going down the interstate, on a highway, and and over a hill. It shuts down and says 'starting disabled, service throttle' with no warning at all. Several people have had the same exact problem and no one seems to know how to fix it. They say wiring but it never fixed anything.
