Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2014 Chevrolet Impala Owner Comments

My Impala 2014 suddenly says 'service stabilitrak' in the display and the engine power drastically reduces. I have see this in forums that is a common issue with GM cars and it happened to me couple of times. This is a very dangerous issue when happens at freeways or any faster traffic routes.

While driving and accelerating to get on the highway the electronic stability control "stabilitract" light popped up on the dash screen and reduced the engine's power, reducing my speed to a maximum of 30 mph when trying to accelerate to the posted 55 mph speed limit. I was traveling in a straight line when the "stabilitract" & "engine power being reduced" information popped up. The car would not go over 30 mph. This caused me to have to pull over and nearly caused an accident due to the slow nature of the vehicle, even with the emergency flashers on. This is several incidents with this particular car, having electronic failure. The worst of it was when the collision sensor was affected by a leak in the car after having to have the windshield replaced due to the rear view mirror falling off. That incident caused the car to slam on it's breaks due an electrical error. This car has been in the shop for numerous electrical issues. Chevrolet has refused to do anything but the bare minimum to get the car back on the road obviously not fixing the root of the problem, as this is once again an electrical issue. Not safe to drive if the electronics are going to continue to fail.

4/27 approx 5:20pm @ 70mph, "loss of engine power" and some stabilty warning came on. Check engine light and traction light lit, was in center lane, thankfully got to the left berm. Car would not accelerate. Turned off, touched brake a couple times, sat a few mins, restarted, ck engine light still on, but engine power warning not on, was able to get into moving traffic and took to dealier 4/27 apprx 7pm, with GM rental given to me. As of 1:12pm, no call yet, not sure what the issue is, but could have been fatal!!!! bad, bad bad!!! took a pic, blurry though, frightening! told dealer of sudden surges, but intake rep said it would all be related and didnt write it down.

Water was leaking down from over head dome light and from door jam, all the main electrical safety controls are housed where the light is in the roof. Called dealership was told first available date to get the car in for repairs is February 22nd. On my drive home from work the collision control came on started flashing the red lights on the dash and slammed on the brakes, like the was a vehicle in front of me has come to a dead stop, except there was no vehicle in front of me, the road was open. I was getting off the highway when this occurred, while driving in a straight line. When home and the car was turned off I'm getting errors saying key fob isn't in the car, and the electronic parking brake needs to be serviced. The car is inoperable at this point. Even if it does start again is a safety hazard at best and has to be towed to the dealership for repairs. It cannot be driven in the electrical state it's in.

While turning vehicle to the right or left, whirring noise occurs coming from front suspension. Notable power loss when accelerating to the right or left into oncoming traffic creating a dangerous situation for occupant and oncoming traffic. When this incident occurs, the traction control light luminates on the dash.

While making a right hand turn at slow speed the automobile felt like the transmission downshifted and then a message came up in the dic telling me to service the "stabilitrak", service traction control, and the ABS lamp illuminated. After have the automobile sat for approximately an hour all of the above messages were no longer visible. I brought the car to the dealership on May 14, 2015 to have it checked out but they could not find any problems. The same problems have occurred approximately 4-8 times now with the information staying on in the dic for various lengths of times.

Impala 6-cyl

  • 2,770 miles
At 70 mph vehicle slowed on its own. Vehicle information center read "stabilitrak and engine power is reduced". got yellow traction control system light on the instrument panel with a "malfunction indicator light" below the speedometer.engine running rough at ashland, va exit.engine was shut down then restarted with same warnings as before.approximately 45 mins later restarted to have a local Chevrolet dealer look at the car. On restart, all warnings and indicator lights except for the "malfunction indicator light" were out and engine ran guessed that it was probably a "glitch" and it was probably ok to drive.the 800 or so miles to sarasota were without problems. On 8/5/2013 took car to local dealer approximately 3 miles from my home. On entering the dealer's parking lot at approximately 10 mph the problem reappeared I.e. "engine power reduced with stabilitrak" with warning lights as before. This is a safety issue as it can happen at any time!!
