Chevrolet Impala Problem Report

Chevrolet Impala check engine light

(7 reports)
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. -
