Owner reports
Selected complaints filed with NHTSA by 2015 Chevrolet Traverse owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2015 Chevrolet Traverse. The contact stated while driving at various speeds, the vehicle speed unintendedly decelerated to 25 MPH. During the failure the message "Traction Off", "Engine Power Reduce" and "Stabili-trac" were displayed. The vehicle was taken to the local mechanic who replaced the accelerator pedal sensor on several occasions, but the failure had eventually reoccurred. The vehicle was recently taken to the local dealer who was unable to reproduce the failure. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 67,206.
All I did was take it to get new rear calipers and an alignment and when I left the shop I got a light on the dashboard that says service traction control service stabilitrak and sometimes the abs goes on and off and sometimes the airbag light comes on and turns off. I can't drive over 1.5rpm and it's jumping when trying to accelerate. I'm not getting codes. I changed the brake pedal sensor to see if that works but no. Mechanic can't seem to figure out the issue without me spending more and more money on it. I've only had it roughly a year and half. I've put alot of money into this vehichle.
Vehicle started bucking and shaking when taking off from traffic light. With excessive speed 50-60MPH that followed the bucking. Tried applying both feet by standing on the brakes. Car started to slow down, only to speed back up until, the vehicle could be shut off. Lights on dash were flashing. On such a heavy traveled, congested road, someone could have been killed. My car is scheduled to be looked at by Dealer.
The biggest problem is that mechanics don't know how to fix this problem. Traction control needs servicing with causes you to lose acceleration on the freeway. Then sometimes stabilitrac also goes off. Now the vehicle engine keeps running when turned off. The air conditioning sometimes randomly won't work at all, and last the tire servicing system now won't sync.
While driving at various speeds, the check engine light, service stabilitrack, and service traction control warning lights came on. Vehicle went into limp mode. Independent mechanic said ongoing issue with Chevy and carbon build up in the throttle body. It will keep happening due to flawed system. Dealer denied but keeps happening
Vehicle shuts off while driving check engine light and traction light turn on.. sometimes starts shaking really bad... also decelerates while driving.. incidents have occurred multiple times within the last 4 months
Recently leased vehicle is a hazard! On different occasions when driving, the vehicle accelerates, decelerates and brakes on its own. Transmission caught on fire with no prior warning. The vehicle can not drive straight, it does not move when placed into reverse and sounds like a car badly out of shape. The vehicle bucks and makes loud clunking sounds as if the different speeds could not kick in. The car has never given any warning on the dashboard for all the issues it presents. Electrical issues: can not charge phone on it. Taken vehicle to the mechanic at the dealership but their reports state no codes available for any possible issue. Only until the car started to burn and show smoke, did the mechanics attempt to fix it. …
I was originally in a parking lot, stopped completely, then proceeded to gently turn left in to a parking space. I barely pushed the gas pedal and the car revved up and took off full speed ahead making me crash in to a hill. The hill is a small landscape space that divides the parking lot and a busy 6 lane street. The front of the car was damaged. I was completely shocked yet thankful this did not happen in an intersection or in traffic. I had the car immediately towed to a Chevy dealership so they can assess the issue and I did not feel safe driving starting it up and driving again. I towed it to the same dealership I had just left from as this same day they had completed a repair on the emissions system. I filed a claim with the insurance company. I'm still waiting to for the vehicle inspection report details.
Tl* the contact owns a 2015 Chevrolet Traverse. The contact stated that while turning into a parking lot at 5-10 MPH, the accelerator pedal was depressed and the vehicle violently accelerated causing the contact to crash into a building. The brake pedal was depressed but failed to engaged properly. No airbags deployed. No injuries sustained. A police report was filed. Medical attention was contacted and took vitals. The vehicle was towed by nationwide to independent mechanic where the cosmetic repairs were being performed. The manufacturer was not made ware of the failure. The damage was to the building and front bumper. No dealer was contacted about the failure. The failure mileage was 39,700.
I was slowly backing out of my garage when all of a sudden my 2015 Traverse accelerated to 40-50 miles per hour to my horror. I felt like I was in the indy 500. The car backed into a tree in my front yard, then at the same high speed lifted off the ground and raced forward and crashed into 2 parked cars in my back yard. Had the 2 parked cars not stopped me my neighbors feel I would have gone into the lake in my back yard. My air bag did not go off, yet the one in the empty parked car did go off. All 3 vehicles were a total loss.
