Recently reported ENGINE problems on 2011 Chevrolet Impala

I was driving down the highway on the homestretch of a roadtrip from pa to fl when the "service stabilitrak" , followed by "engine power reduced" message started flashing. the two lights on the dashboard also went off. since i was in the middle of the highway, i was unable to find a good place to address the issue, and i figured like most times the "check engine" light goes on, that it was something that i could wait to deal with when i got home. i continued driving for about 15 minutes and then the message changed and said "disabling throttle" or something to that effect, and i felt the engine losing power. i was in the middle lane, doing around 55 miles per hour with cars all around me. i immediately put on my four-way flashers and fortunately people in the right lane slowed down and let me coast to the shoulder but it could have been disastrous. i sat there for a few minutes trying to figure out what to do. finally after a few minutes i decided to try starting the car again and it started, with just the check engine light on and i was able to continue on my way. since then it has continued to occur intermittently. i took it to the dealer, but they told me it was a sensor in the gas pedal but that it was not under warranty. *tr

My 2011 impala is reading "service throttle. reduce engine power" and then proceeds to shut down. even after replacing accelerator pedal position sensor, vehicle is still reading same errors. this is very dangerous because there is no limitations to when the vehicle shuts off. after extensive research, a lot of people are having the exact same issue and chevrolet hasn't attempted to do anything about it. please help! *tr

Driving 2011 chevy impala in city traffic. service stabilitrak, service traction control, reduced engine power warning messages received. this has happened several times at intermittent intervals in the two years i have owned the vehicle. in some instances, the engine shuts off and all power steering and power braking is lost making it very difficult to control the vehicle. after research, this is a problem that gm needs to address. i have found that if i pull over when the warning messages display, shut the car off, wait approx 10 min, the car will start again, the messages will be gone, and the car will drive normally. the check engine light remains on and then goes off within a day or two. *tr

I was driving 60-70 miles per hour on the interstate and the engine began to lose power. after a couple of minutes the engine got a sudden boost of power. i was told it is the sensor on the gas pedal that is effecting the engine power and it is not covered by power 100,000 mile warranty. *tr

Tl* the contact owns a 2011 chevrolet impala. the contact stated that while driving approximately 65 mph all the warning lights illuminated and indicated that the engine was loosing power. the contact pulled over and waited a few minutes before restarting the vehicle. the vehicle was later taken to a dealer who diagnose that the app sensor and modulator failed and needed to be replaced. the vehicle was repaired for both components. approximately 1 month later the contact was driving approximately 65 mph and the vehicle started to slow down while he was pressing on the accelerator pedal. after pulling over the vehicle was unable to accelerate but the rpm's were rising. the vehicle was towed to the dealer diagnosed that the transmission failed and needed to be replaced. the vehicle was not repaired. the manufacturer was contacted and they offered no assistance. the failure mileage was approximately 51,000 and the current mileage was approximately 52,000. the vin was unavailable.

This has happened multiple times to my 2011 impala. i will be driving normally, anywhere from 45 to up to 65 mph, and i will get a warning saying "service stabiltrack, service traction control, engine power reduced". usually i can shut the car off and wait 5 minutes, and the messages will clear, but the check engine light will remain illuminated for the next couple of days, eventually clearing. there needs to be a recall for whatever is causing this, because there are a lot of folks with impalas having this same exact problem. we as the consumer, should not have to pay money out of our pocket, for a problem that chevrolet caused during the manufacture of this car. *tr

My wife was driving on the highway and out of the blue the stability control and reduce engine power light came on the message display. there were no weather conditions at the time. this has happened 6 times total. one time it happened as she was warming up the car. all of a sudden it started shaking and she felt as if it was about to take off into space. she turned it off three times - even tried to drive it and move to another parking place and turned if off again before it finally stopped shaking. *tr

I have a chevy impala, 2011, and a month or so after buying it the "service stabilitrak" light came on. before i could get it into a shop, it went off. it came on again yesterday and my engine power all but shut down, i was trying to get through an intersection and thought i wouldn't make it. after researching, i see that chevy has had numerous issues with this. why are they not repairing the problem? this is a huge safety issue for drivers. *tr
