2009 Chevrolet Impala Vehicle speed control Problems

“I was driving alone on the highway and noticed that the rmp gauges was going up and down, then suddenly a message on the dash read, service traction control, then a few seconds later another message read, engine power reduced and the car would not pick up any speed. This was very scary and confusing because the next day I had no isses but has now it did the same thing today. Please help.”

“While accelerating the traction control kicks in and cannot accelerate. This has happened while backing up, driving straight, and turning. It has mainly been happening while driving in the city. When I push the gas pedal the car doesn't move. I have almost been hit by other vehicles while stuck.”

“When im driving on the freeway or driving 35 MPH the car gets on a limp mode and shows a power engine reduce: and traction control and sometimes turns off on me while driving I already replace the (tps) and the throttle body because that's what the car computer was telling me and I already took the car to a different mechanics and they tell me nothing is wring with it.”

“I started my car and the check engine light and service traction control lights both came on. I got on the highway and tried to accelerate to merge into the lane and my car would not accelerate and the steering wheel locked. Luckily I was able to get into the emergency lane before my car shut off, but I was very close to being blasted by an oncoming semi truck. This could've been fatal to me if I had not gotten over in time.”

“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.”
