January 2019 was driving on a very congested interstate 95 at the posted speed limit of 65. A warning popped up on my dash board. Service stabil trak engine in reduced power. It was like I longer controlled my car. The speed suddenly dropped. I went from 65mph to maybe 30mph. It felt like my brakes were being applied . I became scared and almost started to panic. But because I was in the far right lane I was able to pull off the interstate. I sat there on the side of the interstate with my heart racing and my hands locked on the steering wheel so hard they cramped up. I turned off my car and removed the keys from the ignition. I thanked god I was alone in that car. I thanked god the car behind me was not tailgating me. I waited for about 5 minutes and then put the key back in the ignition and started the car up. The warning was gone but the service engine light remained on. I was scared to death to merge back onto the interstate so I put on my flashers and drove on the shoulder at 20-30mph until I got to the first exit. I made it home. I called a car repair company. They told me the sensor more than likely need to be reset. They suggested I take it to a chevy dealership service center. The next day I started my car up and all warning were gone so I did not take it to the service center. The car ran fine until today 52/20/2019. I just filled my tank up with gas. Turned it on put it in gear and drove 20feet when the same error came on . I had looked up this error on the internet. Seems lots of americans have almost been killed because a car maker has a mechanism built in to it vehicle that takes control of the speed to which the vehicle is traveling. People are spending a lot money to fix an issue that seems to not have a fix. Chevrolet is putting the lives and the lives of others on the roads in jeopardy with their stabil trak computer sensors. Your failing americans.
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.
