Cranked up the car to go home. Stability light and "engine" light was on. While on the interstate passing a truck the engine died. Display center indicated service stability track and reduced engine power. Coasted over to rt. Shoulder. Car would not restart for about 30 sec. Cranked it up and made it home. Trouble code is P2138 which seems to indicate the throttle position sensor D/E voltage. Will take to dealer in am.

Impala 6-cyl

  • 52,530 miles
The malfunction indicator (page 5-17 in my manual) came on and the message was to prevent serious damages, go to your service station immediately. I was in the parking lot of a grocery store, and made my way to the interstate heading to our service station when my car stopped dead in the middle of interstate 485 about 3 miles away maybe ( about 7 miles from home and our service station). I was in the far left lane of a major hwy that was/is under construction when I felt something unusual. I grabbed the steering wheel as hard as I could between the cars and just made it to the far right side of this major highway. The steering, A/C and brakes were gone and then I realized if I did nothing I would have been run over by the trucks on this interstate. I got close to the guardrail and collected my wits and called both aaa and the charlotte nc police. Fortunately I did not have the opportunity to see if the air bags would have gone off! the nc police were to come immediately but never showed up, but an hour later the aaa driver came and assisted to help me out of my car into his tow truck. He said to sit in the ac and drink some water. It was a hot day in the carolinas. No ac, nothing to drink and could not open my windows. I could not open my door as cars whizzed by me on the driver's side. The car just died. Finally got it towed to the Chevy service station and the repairs cost (enclosed) $696.84. After seeing the event on tv I realized I could have been killed!!!! please do something about his issue, as I hear all the horror stories of the innocent killed upsets me. I was fortunately to be able to get me and my car off the highway while cars whizzed by on a busy highway but how many haven't.

When my Impala was 4 years old and 42000 miles(April or may of 2013), both rear door locks refused to lock or unlock. I contacted my dealer and he stated that it was out of warranty. I then contacted gms customer service which reiterated the same thing. After investigating online, there are quite a few blogs with customers who have the same problem. To replace these locks costs approximately $800. I contacted your organization this morning and they told me to contact Chevrolet at 1-800-222-1020. When I contacted them, I was informed that the serial number did not fall under any recalls. However, Chevrolet does have a door lock recall.

The contact owns a 2011 Chevrolet Impala. The contact stated that there was a knocking noise heard from under the hood. The contact took the vehicle to the dealer where it was determined that the air conditioning orator had failed. The VIN was not available. The failure and current mileages were 50,000.

Driver side window switch would not operate ( intermittent) at times. The switch was replaced by the dealership (young Chevrolet). During the past month (6/13) the same type of condition has occurred. This problem sounds much like what is happening with NHTSA id - 13V248.

Impala 6-cyl

  • 80,000 miles
I own a 2011 Chevy Impala and for the past couple months on 6 different occasions as I am driving down the freeway my engine power is reduced and "service stabilitrak" light appears. As I have researched and have found that this is a common and very unsafe problem among GM vehicles. I have also found that there is no clear solution to why this is happening with many mechanics stumped and replacing parts in which the problem recurs only a short time later. I have also found replacing what the diagnosis of code P2135 says the problem still may not be solved. As one can imagine that driving down the freeway with a semi, heavy traffic, etc. And losing engine power may lead to significant negative results. I have not installed any parts other than tires after purchasing of vehicle.
