To whom it may concern: I have a 2009 chevy impala with 100,000 miles on it. The 1st time this issue happened, I was driving slowly, on a side street, in july 2019. Out of the blue, the following warnings appeared: engine power is reduced, service stabilitrak, service traction control. Immediately my car started running horribly (it didn't want to go, was chugging, and almost felt like the transmission was slipping). I parked it. Later I started it and all warnings were gone, but the engine light was on. . The next day I started it and just the engine light was on. 3rd day I started it, engine light still on. Drove it to a shop,.right before I pulled in, the light turned off! They scanned it anyway & said that nothing came up. The car has driven just fine, no warnings or lights until 11/25/2020. I was driving about 20mph, turned right on a side street and all of a sudden all of the exact messages as before came on. Vehicle immediately started running slow and "chugging"again. I parked it. When I started it again later, all the same messages were still there. It's definitely scary when this happens & since the 1st time it happened, I was nervous to drive it far because I wasn't sure when it may happen again. I went on a chevrolet forum & read there was a recall for this issue. I was very pleased about that. I put in my VIN & it stated that there are no recalls. So I called gm this morning. The rep said they're aware of this issue, but there is not a recall for it. She then said that it would've covered by special warranty but unfortunately that was unavailable as of april 2019! Her advice was to take it to a certified dealership and have it checked and fixed soon for my safety! I asked why there isn't a recall, if it's a known issue and she said I could talk to a customer experience manager at the dealership and maybe they could do something for me. Please help!

This is not the first time this has happened. On the hwy going 60mph, all of a sudden my engine power is reduced and airbag light came on. The next day the air bag light and engine light are both on. Went to my mechanic for an inspection (which I failed due to the airbag) and he informed me to contact the dealership for recall. I did, only to find out the recall is closed and I can't get this fixed unless I come up with a lot of money. I explained I never got anything from the manufacturer about the recall. How can I get my car fixed on a closed recall?

This has been happening for several years, and happened again yesterday..... Pulled out onto 4 lane divided highway and traction control light came on, dash said "engine power reduced", but did not seem to be significantly low on power. Drove about 5 miles down the road, then car suddenly died. Was able to pull over to side of the road (with three small children in the vehicle), tried to restart the car but display said "starting disabled, service throttle". Waited about 5 minutes and car restarted. Was able to drive home, no reduced power but check engine light remained on. I have seen many comments online from others who own similar gm vehicles that have had similar issues. We have also had similar issues with our 2011 suburban, although no stalling. There should be an immediate recall for all 2008 - 2011 gm vehicles to repair this issue, most likely accelerator pedal position sensor.

Drove my vehicle to attend church on a sunday morning. After church, return to my vehicle to go home. I started my vehicle and put it in drive gear. The vehicle wouldn't move. I shifted it to 2nd gear and it moved slowly and I was able to drive home. I got no prior warning of any problem before parking. No check engine light and it scared me because it could have occurred while I was on the busy interstate. I have not had it repaired because the problem can't be isolated by the transmission repair shops because there is no check engine light on. The transmission shifted fine prior to this. The vehicle only has 117,000 miles.

While driving on roads and interstates, I frequently receive a dash notification "engine power reduced" and my service traction control and check engine light comes on. When this happens, my vehicle loses speed and cannot accelerate above 40mph - dangerous, especially on an interstate. The notification lights and symptoms occasionally go away after turning the engine off and on, only to come back later. I cannot find and answer to this problem.
