2018 CHEVROLET TRAVERSE Complaints

Shift to park. Car won’t turn off and me and kids are stuck in car. 2nd vehicle this has happened to. This is very dangerous as my car is stuck on.

Shift assembly has failed twice - April 2021 and April 2024. For this latest occurrence (April 2024), the vehicle spontaneosly stops registering when I shift into park. When I shift, the vehicle sends a warning to shift into park. There is a safety concern because I cannot determine whether or not the vehicle is actually in park. The GM dealer has determined that the issue is a faulty shifter switch and harness and a faulty shift knob. The issue occurred and was repaired in April 2021. The issue began occuring again, intermittently, in January 2024. Issue became consistent (inability to shift to park) about March 2024. At the same time, the parking brake/stabilitrak began engaging each time the vehicle stops (e.g., at stop lights, etc), which has caused premature brake wear. In April 2024 the following parts were replaced: Shifter switch (Part #84955381) Harness (Part #84733196) Brake rotors Brake pads

Shift to Park error occurs everytime I put my car into park. It does not turn off and the vehicle remains on until I jiggle the shifter. This has been "repaired" 2x under warranty. Now that it is out of warranty the manufacturer refuses to cover any of the expenses on this known issue with a bulletin per your website (18-NA-297).

The transmission on my 2018 Chevy Traverse went out per the mechanic that recently inspected it. It was just purchased from a Chevy dealership not even 8 months ago. I first noticed the problem a couple weeks ago when my car hit about 25mph getting on the highway then wouldn’t go any faster as I would try to accelerate speed, then it was jerking and was harshly engaging from time to time. Then it finally felt like someone crashed into the back of my car it jerked so hard and then accelerated but only went up to 40mph and wouldn’t go any faster. It would hit 40 mph and then idol at the speed when you would hit the gas to accelerate. No engine light came on or anything at that time. Then a couple days later the shifter would be put into reverse and then not go in reverse when you hit the gas to go. Having two young kids, my husband told me it wasn’t safe to be driving it at all. We had it towed to a mechanic shop to be inspected since we depend on a car for our job. The mechanic inspected it with a diagnostic code reader as well as looking at the transmission. The overall condition is that the transmission is not working anymore. I have done research and for this specific make, model and year there are tons of recalls for the transmission.

I was driving and just passed a vehicle while accelerating when I heard a pop noise, saw a lot of white smoke through my rear view mirror, had the engine light go on and the vehicle stopped working. I slowly pulled over to the side of the road and placed the vehicle in park followed by turning off the car. A person driving by stopped and advised me my vehicle was on fire under the undercarriage. I popped the hood and the engine was also in flames. I was unable to put out the fire with a fire extinguisher and the local fire department and law enforcement agencies helped to put out the fire. The vehicle was a complete loss. If it were not for the passer by person telling me the undercarriage of the vehicle was on fire, not sure if I would have known in time to get out of the vehicle safely. The root of the cause is under investigation by my insurance company. 2018 Chevrolet Traverse LS

My quarter panel taillight has stopped working due to moisture in the light (no visible breakage on light). This part is on continuous backorder with no ETA of coming back in stock. Dealer has ordered part but will not give a loaner car. GM acknowledged backorder but will not give rental reimbursement. I have three children I am to put in this car that does not have a left turn signal or brake light. I feel unsafe driving this car as I may be rear ended but everyone I talk to says they can't do anything. What am I to do.

The contact owns a 2018 Chevrolet Traverse. The contact stated that upon the start of the vehicle, an abnormal rattling sound was coming from the vehicle without warning. The contact stated that once the engine had warmed up, the rattling sound turned into a chugging sound. The vehicle was taken to an independent mechanic where it was discovered that the bracket used to hold the exhaust pipes together had rubbed against one of the pipes and formed a hole. The mechanic then explained that if not repaired, the catalytic converter would become damaged. The dealer was notified of the failure and an appointment was made to have a diagnostic test performed. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was 117,600.

Exhaust cracks out creating a hole and cause’s problems with the catalytic converter. This is exactly the same problem as on the 2019 and up traverse that they have issued repairs on
