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.

While driving northbound on I-75 in southern ky, the car suddenly lurched a little and "traction control" and "stabilization" errors displayed followed by "reducing power." And, the check engine light came on. I called my Chevy dealer and asked if it was safe to continue driving - they said yes, as long as the check engine light wasn't flashing. We went about 5 - 10 more miles and the display flashed something about throttle problem and then "shutting down engine", which it did immediately with no warning while we were doing about 70 - 75mph in the middle of the 3 northbound lanes of I-75. I had to try to steer to the shoulder with no power steering or brakes. Once there, I tried to restart the car and nothing happened - it displayed "starter disabled." We called our road service and they took our info, found the nearest Chevy dealer who said they could work on it asap if we got it in there. While they were working on setting up a tow I tried starting it again. It started but the check engine was still on. I tried driving a little along the shoulder and it seemed ok so I said we'd try driving to the dealer rather than wait for a tow truck. We made it. They got on it fairly quickly and found the problem was the gas pedal position sensor. We were fortunate that the traffic was light and I could safely pull off. I hate to think what the results would have been if this had happened earlier as we were traveling thru atlanta with its 6 lanes of heavy traffic. Suddenly losing power and control in that traffic would probably have caused one of those multi-vehicle accidents that make the national news. What kind of incompetent programming of the car's computer would trigger a full, instant shutdown because of a faulty accelerator pedal position sensor? I would suggest an immediate recall to re-flash the computer to eliminate the no-warning shut down.

While driving down I 80 West of princeton ill the check engine light came on followed by the check traction control light.the dash then light up like a christmas tree with lights I had never seen and can not duplicate with turning the key to on.the car immediately died and I lost power steering and brakes.I got the car stopped safely.I called a mechanic in the town I live in and he asked if it would start again. Earlier when I tried to start it acted as though the battery was dead. This time it started and I drove it home.a local repair shop replaced the gas pedal.I had bought this car new and it has never been in a crash or had any repairs done besides routine service. No one was hurt but this car should not have shut off at 70 mph because of a defective sensor on a gas pedal.I am a retired state trooper and I am sure my training saved me from being in an accident yesterday because I happened to have other cars and semi S driving near me.

It had snowed overnight and I was driving 60 miles per hour going downhill when the traction control light and the engine light came on and then where the odometer reading is it said engine power reduced and then check traction control and check stabilizer. I did make it to work as the car shock as the car felt like it was going to die. I did let it sit all day while I was at work and then when I started it the engine light was still on and it ran ok. I took it across the street and parked it at the Chevrolet dealership and since it is Sunday they are not open and I will stop by in the morning to let them know what is wrong to have them check it out. We have had this car for a year and considering not owning another Chevy.

At the time of the first incident traction control light came on the low engine power light came on.speed dropped down to 15 mph. Had to pull over turn car off. Then restarted it again it was fine for a month. It repeated same problem. Now check engine light stays on.hdhad code read saying throttle cable and traction control.to me that is a serious issue. This is something that needs to be addressed. Highway driving this problem could cause an accident.I can see this has been a issue with General Motors with Impala and other models since 2008.how many of the same complaints would it take until its fixed.complaints keep coming up after throttle bodies replaced still having same problems. General Motors needs to get with the program.

I don't remember the exact date, but approximately 2 yrs ago, I began seeing the sequence of messages, "service traction control, service stabilitrak, engine power reduced, " and the engine light comes on along with the traction control system light. The car speed was obviously reduced and I couldn't really accelerate. I took the car back to carmax and they said they couldn't find anything and did not know what I was talking about. It happens sporadically, but seemingly always on the interstate while I'm traveling around 65--70 mph. This is very dangerous, and I've been trying to research what needs to be fixed. I do not understand why this is not a recall item. I think this will be the last Chevy I purchase!

My wife was driving on interstate and all of a sudden lights start flashing on dash board saying traction control, engine performance reduced and check engine light comes on. Car completely shuts down on major highway. GM needs to do something!!!! before someone seriously gets hurt or worse. Went to auto shop and they said it is the accelerator pedal sensor gone bad already at 56,103 ? I just bought the car, and only had it for 1 year. I will never buy anything GM makes or recommended there vehicles to family or friends this is ridiculous. Someone needs to care about public safety because obviously they do not. Please do a recall and save a life !!!!!

- Northport, AL, USA

My car is having issues with the service traction control, engine power reduced and will shut down. This has happened to me over 5 times now. I can't even pick up speed after this happens. I was on the highway one time doing about 65 and the car just shut down, I was on an incline/ramp and an 18 wheeler was behind me and I could have been killed. I have taken the car into to get the codes ran but can not seem to get to the root cause. I am thinking about just giving the car back and having it go on my credit.
