2014 Chevrolet Traverse: sudden loss of power

Filed Oct 1, 2025 · Electrical, Engine · MN

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.

Multiple issues have occurred with this vehicle. I have had major unsafe issues while driving while on the freeway and streets where my vehicle reads traction control off and engine power reduced which leads my vehicle to lose all power and shut down being stranded and almost hit multiple times while by myself and while my husband and children are present. I believe I am the second or third owner of this vehicle and I was never given any information about any recalls

I have been receiving warning messages on my dashboard regarding Service The Stabilitrak, followed by Traction Control Off message and then vehicle shaking, losing steering power and engine shutting down for over a year. The issue occurs randomly making it difficult to repair. I have had it serviced multiple times by different mechanics and no one has been able to find a solution due to the random nature of the issue. This poses a risk to the vehicle occupants safety because when unexpectedly and suddenly losing engine power, steering and traction control all at the same time, it is very difficult to safely merge to the shoulder of a roadway. I have been left stranded in many locations including out of town. Due to my research this is a common issue with this vehicle that can be caused by multiple issues. I also have a recall on my air bag and warnings have appeared on my dashboard that has no remedy yet. The vehicle is not safe to drive and I depend on this SUV to transport my family of 7. I am also still financing, making it difficult to keep up with payments while trying to diagnose/ repair.

While driving my car, the instrument panel just went blank. My gages all read 0. No speedometer, no battery voltage, no fuel level. The driver information center also shut off. Blinkers would not work, door lock/unlock button did not work after stopping the car. The engine never felt like it lost power and my car would still drive but I could not signal or see how fast I was going.

[XXX] I WAS GOING DOWN THE INTERSTATE AND THE STABILITRAK, TRACTION CONTROL, CHECK ENGINE LIGHTS ALL CAME ON. ENGINE REDUCED POWER LIGHT CAME ON I LOST ALL POWER OF THE VEHICLE, I WAS IN HEAVY TRAFFIC AND FORCED OFF OF THE ROAD BECAUSE MY ENGINE DIED. I WENT FROM DOING 70 MPH DOWN TO 10 MPH AND CAME VERY CLOSE TO GETTING REAR ENDED. This would have caused a chain reaction rear end crash with multiple vehicles. WHEN I GOT TO THE SHOULDER OF THE ROAD I WASN'T ABLE TO GET MY VEHICLE STARTED. I waited about 10 minutes tried it again. It turned over with yellow engine light remaining on. THIS HAS HAPPENED ON MULTIPLE OCCASIONS. 1 HAVE SEEN WHERE THIS IS A PROBLEM IN THIS YEAR MODEL OF THIS VEHICLE AND WONDERING WHY IT HASN'T BEEN RECALLED YET BY THE MANUFACTURER BEFORE SOMEONE LOSES THERE LIFE. This is my only vehicle and I feel that it is unsafe to drive. I have a one year old granddaughter and her safety is at risk. Please help fix this problem as we need a car to drive.

2014 CHEVY TRAVERSE LT. Randomly driving on the freeway @ 60-65mph going uphill it started losing power. It started stuttering/coughing. The TRACTION CONTROL OFF and SERVICE STABILITRAK lights flashed. I finally got it home and shut it off. The next morning it drove fine. Then it happened agai a few days later. I replaced the throttle body after it was diagnosed as the problem. On the way home it did the same thing. It wasn't the throttle body. Now they can't find out what is wrong with it. There are no codes. The service repair guys say it is overheating in the shop but not when they drive it and they don't know why.There are no codes. I told them it was random. If I am driving on the Interstate and have these problems and have to turn off the engine and sit for any amount of time is dangerous. Especially if the heat is over 100 degrees as it has been. I'm not sure if it is related to this problem, but my control panel lights go from dim to light randomly. I can't see anything on them during the day when dim. No warnings etc that may flash

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.

When driving the vehicle will have a sudden lose of engine power with no warning signs. It will say “engine power reduced” then say “service stabilitrac”, and “traction control off”. This morning when it happened I was turning into a parking lot to drop my kids off and almost hit a sign because the engine completely stalled mid turn. I have also had it happen to me on major highways.

I recently purchased a 2014 Chevy traverse LT. While driving on a four lane busy road with a 65 mph speed limit my vehicle without warning said “traction control off, reduced engine power” and within seconds I had no power stealing and I went from driving 65 mph to 10 in less then 10 seconds, the car started violently shaking as well. I had to aggressively redirect the steering wheel to get to the side of the road and turn the vehicle off & wait a few minutes & restart it. It seemed to fix the problem. Within a week it happened again, on the way home from work, and I was nearly rear ended at a 60 mph speed and I am now terrified to drive the car more then a mile up the road to my kids school, I have two small children and this has put us in an almost near death situation TWICE! I purchased this car so I would have a reliable vehicle for my kids and I and it’s been terrifying for my children and I to own this Chevy! The dealership I purchased the vehicle from is over two hours away, I also live in a rural area so to have it diagnosed I’d be having to drive at least 15 miles and I’m terrified to do so

On more than 5 occasions my car will say “traction control off” and “reduced engine power” then just shut down. This is very dangerous and can cause an accident. I took it in serval times and mechanics report that there is not issue that they can see. The check engine light with come on and off randomly.

This is the second time this has happened while driving along at highway speeds unexpectedly get error messages, service traction control, service stabilitrak, traction control is off, engine power is reduced. The first time I was able to drive to a dealership. The second time I lost all power and was lucky that I was in a residential zone
