2014 Chevrolet Traverse power train problems

“While driving my traction control turns off and reduces power to the vehicle often stalling it making it hard to safely move to the side of the road.. has been happening since I got the vehicle from a dealership”

“My car has been having a problem with traction control/service stabilitrak and losing power to the engine since I purchased it. The problem was only occasionally, now it does it EVERYTIME I drive. First it pops up with traction control off message, once that happens it starts to lose power to the engine making the car(heavy car) shudder so bad I cannot drive. The transmission lags on acceleration and it also pops up with "service stabilitrak", "Power loss to engine "And the car will not move until I can pull over and turn it off. Very scary. I have 4 kids and its losing power while Im driving on the highway. Ive replaced sensors, Cleaned the throttle body and also changed spark plugs and changed fuses. It's very dangerous and I found out this is VERY common , especially for my year.”

“For at least 5 years, we have been consistently encountering this same problem. After driving awhile, typically at higher speeds, we will get a error message saying to "service stabilitrack and traction control" and "traction control has been turned off". Often this is accompanied by significant shaking of the vehicle and steering column, random gear shifting, impeding your ability to control acceleration and sometimes causing steering issues. We have taken to our mechanic numerous times, and he is unable to diagnose the issue. A code reader returns: ABS-TCS Brake Switch Circuit malfunction. This issue is well-documented in vehicle forums online (Google: Chevrolet Traverse stabilitrack or traction control.”

“There is a problem with the stabilitrak system that causes the vehicle to shut off while driving. This turns off the traction control and reduces power to 3 cylinders, thus causing the vehicle to go into limp mode and can cause an accident. This problem is intermittent and the dealers can't seem to find the underlying issue. It will happen whole parked, stopped at an intersection or driving at highway speeds. I have had this happen while driving in heavy traffic on the freeway and in the number one lane. My vehicle lost power and I had to try and negotiate three traffic lanes to stop along side the freeway. I had to put the transmission in park and shut the engine off for 15 seconds in order to clear the code and safely proceed back into traffic. The check engine light remains on for a period of time, but will clear itself. This is unsafe and needs to be address by GM as it is happening to multiple model types in GM vehicle lineup.”

“With no warning the steering wheel locks up and the engine reduces power and starts saying service traction control and stability track. It doesn’t his in rush hour traffic going 75 miles an hour.”

“The contact owns a 2014 Chevrolet Traverse. The contact stated while moving from a stop position the vehicle failed to accelerate above 10 mph but then would inadvertently accelerate 40 seconds later and remained in second gear. The vehicle failed to shift gears as designed. The contact stated that the check engine warning light was illuminated. The vehicle was diagnosed but not repaired. The manufacturer was informed of the failure and informed the contact that the VIN was not under recall. The failure mileage was approximately 140,000. The consumer stated the vehicle was taken to three different mechanics and the problem still occurs.”
