I was traveling West bound on interstate 22 when the stabilitrak requires maintenance displayed across driver's information center. Next the traction control light and display lights up followed by, reduced engine power, in which I lost almost all power to my vehicle. I was traveling around 70 mph in the left lane and had to navigate two lanes of traffic to reach a safe spot on the shoulder of the interstate.

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!

2010 Chevrolet Impala. Consumer writes in regards to vehicle sudden acceleration caused by sticky throttle accidents before receiving accelerator pedal position pedal sensor and throttle position sensor recall notices. The consumer stated she was backing out of the driveway, when the vehicle took off like a missile. It traveled across the street, jumped a curb and hit a parked vehicle in the driveway causing damage to both vehicles. The dealer claimed there was nothing wrong with the accelerator. However, the accident was caused by a sticky throttle. When the second accident occurred, the consumer was attempting to back the vehicle up, but instead it accelerated backwards at a high rate of speed making a high pitch whining noise. The consumer quickly applied the brake. However, it not reduce the speed. The consumer hit an oak tree, and in doing so, caused the tree to fall on the vehicle. The vehicle was totaled. Between the first and second accident, the throttle was repaired and the accelerator was replaced.

Engine power dropped significantly on a two lane hwy. Traveling at 60 mph. Almost got rear ended and experienced road rage from driver behind me. Scary. I then noticed a service traction control warning, and engine speed reduction notice. Cruise control would not function. This warning will clear itself but continues to occur. I took it to my mechanic several times and they can not identify it even when the warning and condition is active. Veh. Mileage 126700.

The contact owns a 2010 Chevrolet Impala. While driving 20 mph, "service stabilitrac and traction control, may lose some engine power." Was displayed across the message board. The vehicle was taken to a dealer where it was diagnosed that the line that goes to the accelerator pedal needed to be replaced. The vehicle was repaired; however, the failure recurred on numerous occasions. While driving 20 mph, the vehicle stalled. The contact did not attempt to restart the vehicle. The vehicle was towed to a dealer who diagnosed that the line that goes to the oil sensor was corroded and needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 42,000....updated 01/20/16 updated 02/05/16

As I was driving on a state route, alerts appeared for "service traction control" and then "service stabilitrak" followed by "engine power reduced". the engine light also came on. I pulled over and shut the car off, waiting a few minutes before restarting. The messages stopped, but the engine light was still on. I drove a few more miles and approached the on-ramp to the interstate. As I accelerated to merge onto the interstate, the same alerts came back on in addition to "starting disabled, service throttle". shortly thereafter, my car became completely disabled and shut down as I was on the interstate- the engine cut off, no power steering, no acceleration!! thankfully, I was able to safely pull off the side of the interstate. I had the vehicle towed and the car started right up and seems to run fine at the repair shop. Worried when and where it will happen again.

The contact owns a 2010 Chevrolet Impala. The contact stated that the reduced engine power warning lamp and the service stability traction control warning lamp illuminated. Each time the failure recurred, the speed decreased to less than 20 mph and the vehicle shook and vibrated abnormally. The vehicle was towed to a dealer who replaced the throttle body position sensor. The manufacturer stated that the accelerator pedal position sensor was to be replaced in a special condition coverage customer satisfaction campaign. The failure did not recur from the dealer's repair which was over a year ago. The manufacturer was notified of the failure. The approximate failure mileage was 60,700.

On or about May 17, 2015, I received notice from the Chevrolet division of General Motors that my vehicle "may have a broken solder connection within the accelerator pedal position (app) sensor. This condition may result in reduced engine power and loss of traction control assist." According to them, I will know when my information center displays the warning and then they will be willing to correct their poor workmanship, but not until that time. GM goes on to inform me that I may be without my car for an extended length of time while they order parts and do repairs. I don't see why I should be the one who will be inconvenienced for their lack of proper workmanship. Furthermore, I feel there is a safety issue here also. GM needs to correct this problem before it causes needless harm to someone.

The gauges on the dashboard fail during driving. The passenger airbags turn on and off during driving. The tire pressure monitoring and fuel gauge warning comes on during driving even though fuel and air are fine. Sometimes at 0mph the gauge will be stuck at prior speed. Gauges fail when passenger airbag turns off. Incidents occur seemingly only when a passenger is present, when passenger airbag is turned on.

I was driving my car on the hwy going about 70-75 mph when it happened to me. The road condition was nice with no signs of water on the highway during the hours of 2 pm, great sunny day. The car jerked on me like the throttle was going down. Afterwards the car jerked again and the traction light notification started to beep and the car idled down and I couldn't increase my speed. I continued on the hwy assuming it would rectify itself but my girl (who mainly drives the car), informed me it's been doing this for over the past year off and on probably once every other month. That the weather condition didn't matter it would pop up and slow down and she'd have to pull over and wait about 10 minutes after turning off the car to turn it back on to be able to continue about her day normally. I continued to drive but it never did fix itself. I had to finally take an exit and stopped at a gas station. Might as well take a break while. After about 10-15 minutes, I cranked the car and the issue seemed to resolve itself and I had no further problems throughout the rest of the day.
