While driving my Impala, with no warning, my car lost power. The dash beeped at me and said reduced engine power, service stalinktrak, service traction control. I had to turn my car off, I waited a few minutes then turned car back on. The car was able to run and drive after this, but my check engine light was on. I had vehicle computer scanned and had a code for throttle position sensor. After further research, I have learned I will need to replace the whole throttle body. My car has now lost power several times and my RPM gauge 'bounces'. I will be parking my car until the part comes in. This was very dangerous as you lose all power with no warning going down the expressway.

Reduced engine power lights came, on traction control light came, on it was hard to accelerate in the middle of a highway, car almost shut down, but I made it home. It has happened twice on the highway and turnpike. I thought it was oil but that wasn't the issue. It stops (the problems) after I shut the car off for an evening, but I'm scared it will power down while on the highway again. When this issue happens the car beeps, then the traction light comes on with warning and so does the engine light and reduced engine power warning. Always in motion, especially higher speeds than normal city streets. Such as turnpike and highway.

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.

The check engine light comes on and it says service stabilitrak reduced power engine. Then the car slows, it may jerk, or stall. This has been an ongoing issue. I've taken it to be looked at least 2 or 3 times. I've been told they don't see anything and I should bring the car in to get serviced the light comes on. It usually last a few days but it will come back on. I've also received a letter from Chevrolet about fixing it but when I took it to get serviced I was told that it had to be under a certain amount of miles. This is a safety hazard and could cause a potential car accident or even death if traveling at high speeds and then all of a sudden your car engine reduces power. I know this because I've almost been in an accident twice due to this issue.

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.
