My check engine light will come on then it will display engine reduced power service traction control, I have not gotten this problem fixed yet I'm not sure where to even begin.
Driving on beltway, engine light, then, engine power low and stability light ALL came on. I felt a slight hesitation while driving. Drove to dealership , the lights never came on !! Have no clue what to do !!!

I just got the problem this weekend. Husband pulled the throttle body plug and cleaned air condition and air intake filters. Disconnected the battery to clean up terminals etc. When I started the car everything was cleared. I have driven about 30 miles and not lights or messages have come on.

My problem is I get a service traction control device message then a message that says reducing power and then one that says killing throttle and my card dies. This happened to me on the freeway last week. I lost all power, power brakes and steering too. I was dead and had to drift to the shoulder of the freeway. My car wouldn't start at all for 2 tries then when I was able to get it going I could only go up hill 40 mph but down hill I could coast at 80mph. The messages go away and then come back and it happened again the other day. This is a big issue and dangerous. I don't know how to fix it. I saw a YouTube video and a guy had the same problem. He fixed it by replacing the gas pedal. I also know each hub has a censor on it so maybe it's that? Idk, but my engine light is ok today and everything is working again. Let's hope it doesn't stop in the middle of the freeway again.

I have a 2006 SS 5.3 Liter engine I can start the car and it shuts off displaying (STARTING DISABLED SERVICE THROTTLE,SERVICE TRACTION CONTROL AND ENGINE POWER REDUCED)I wait a few mins and restart the car and it will start but do the same thing after about 10 mins running
my car will stall for a couple of days before my service traction control message comes up and right after then my engine power is reduced message comes up i took my car to a shop they said my trottle body needed to be cleaned but it is still doing the same thing.
