Check engine light came on. Message came across saying reducing engine power. Then said to service stabilizer. It then turned off traction control. We were driving home from vacation when this happened. After a bit driving the whole car shift off while driving 60mph on a busy highway. The message on dash said it disabled our starter. We almost did not get off the road safely we were in the left lane and could not get to the shoulder. My husband had to make the decision to pass across into oncoming because thankfully there was no one coming.

I was driving on the highway and received the following message, service stabilitrak - reduced engine power. This has come up a few times. This time though while still driving my engine power was greatly reduced with the error, "starter disabled, service throttle". this led to a drastic decrease in speed with zero control over throttle and moved to the shoulder and the car rolled to a halt.

On 1/29/16 my car died and towed to dealer where I was told I need a transmission. The car only had 69000 6months ago dash board lights lit traction control, reduced engine power service stabilitrack ABS.when I would step on the accelaretor pedal it would make a winding noise go to the floor and pop back up again. As I was driving down the highway all of a sudden I had no acceleration car had died. L pulled to the side of the road a few minutes later started up again this happened numerous times I told my son he couldn't drive the car because I felt it was unsafe. I called the GM they gave me a coupon to have the a diagnostic check on it. In Sept I went to the dealer and he scanned my car for codes I was told I needed a right front hub part number 13582664, a right wheel speed sensor harness, 10340314, accelerator pedal, 84018392, and a vent valve 2085252. I can't believe a car dealers would let a person leave not informing the customer what a safety issue this is. I drove the car for a day because I couldn't afford to fix it and was trying to come up with the money again the car died on me as I went to accelerate now the car is sitting in my yard dead as a doornail. I called the dealer and explain the situation to the dealer at lannan Chevrolet in woburn and I spoke with the owner and the only response I got was what do you want there's a hundred thousand miles on the car I have been doing lots of research on this particular vehicle and I'm appalled between a 2008 and a 2011 there has been hundreds of complaints about the same issue.these are safety issues where people can get killed. Out of all these safety issues there's not one investigation that has been opened in regards to the issues. NHTSA or GM needs to open an investigation immediately on these cars. There is a major safety issue and a recall is necessary.VIN number..(xxxxx) redacted to protect personally identifiable information pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Driving at about 70mph my check engine light came with with the reading service stability track, engine reduced power an disabled started, service throttle instantly I loss all rmps an my steering wheel almost fully locked while the car was still on motion. Luckily I was able to jus barley veer off the road into safety. Why would a car company have something like this in thier vehicles. That would lock the steering wheel while going at accelerated speeds

Loss of power steering at startup, becomes intermittent after driving for a few minutes, then service stabilitrack notification comes on sometimes while driving. The stabilitrack notification will come on while making a turn, doesn't matter if it is a right or left turn.

'takata recall' while driving on the highway, my vehicle will lose power, which cause the vehicle to shut down. On the dashboard, service airbag appears as well as the ABS light and lock mode comes on. The vehicle key will not turn to off mode until a few seconds. Then once the vehicle allows the key to turn to off mode, U have to wait a few seconds then the car will start with no problem and the ABS and lock signal on dashboard goes off. This has happened several times in one trip on the highway. This is not safe at all because the steering wheel also get stiff and the traction control comes on the dashboard as well. What can I do about this" should I take my vehicle in to the dealership" the last time this problem happened to me was March 14, 2019

Car gets service stabitrack, traction control and ABS warning on dash. Replacing wheel hubs with sensors does not fix this issue. Sometimes the car will want to apply brakes while driving or reduce engine speed. I have been through many forums with people reporting the same issue on the same car and through multiple years of manufacturing. From the research I have done in the last few days it looks like hundreds of owners have reported this issue but Chevrolet is not doing anything to correct it. Not sure at this point if it is the wiring harness causing the problem or if this could be something with the computer that controls the stabitrack, ABS and traction control. If cars are loosing power and or the brakes are being applied with out driver control this can lead to dangerous driving conditions for the car owner passengers and everyone else driving on the same road. With how many people are reporting this I do not see why the car owner should need to pay thousands of dollars to diagnose and maybe fix the issue. From what I have read some people have had to pay for multiple service events and the issue still not resolved.

When driving the stabilitrak light reduced engine power light comes on along with the check engine light. My car slows down and sometimes it would stall when stepping on the gas and the gas pedal would sometimes shake. After shutting the car off for about an hour or so the stabilitrak light would go off and after a day the engine light would go off as well. Whenever I take it to the mechanic to have it diagnosed and fixed they are not able to find anything wrong with it. This happens without warning often even when driving on the highway and frightens me with hopes that it does not cause an accident that could seriously injure myself or others, or cause a fatal accident.

You really want to know what I think? ok...here's what I think. I think that is beyond comprehension and personally I think it's illegal that GM can get away with not having to put out a recall for the "engine power is reduced" issue that just about every make and model of GM vehicles have. It's not only time consuming to try and figure out what the fix would be because it's not always the same thing wrong on each vehicle (and when you do have it fixed it doesn't last very long until the "engine power is reduced" warning comes back), it's also very expensive but the biggest problem is that it's extremely dangerous. The power is reduced and actually turns the car engine off no matter if you're driving or not. It shut my 2011 Chevrolet Impala engine off as I was driving down the interstate. Thank god there was very little traffic or it could have been catastrophic. I didn't realize how big of a problem this was until I started researching the problem. It's absolutely criminal that you pay your hard earned money for a vehicle and it not only isn't what you thought you were paying for but it can actually take your life and ruin your family because GM's bottom line is more important than their customers lives. I've filled a complaint on this problem already and if something isn't done and it's the cause of grief for my family I will make it my mission to make sure GM not only fixes their crappy workmanship but that they also dig into their bottom line and compensate their customers for the heartache and grief they have caused. It's a pretty simple fix for them and that would be to acknowledge the problem and just fix it, but I just don't think they care enough to do that. I've always been a Chevy guy, but after this Impala I will never own or drive another GM product for as long as I am around. That's what I think. Signed, Chevy guy forced to not be a Chevy guy
