2020 CHEVROLET TRAVERSE Complaints

The vehicle just suddendenly shuts down when driven on the freeway, according to Tillery Chevrolet GMC the engine cracked and needed to replaced for total of $17,291.94

The backup camera system on my 2020 Chevrolet Traverse fails repeatedly and intermittently. When shifting into reverse, the camera frequently displays a black screen, a crossed-out camera icon, or an error message indicating the camera is unavailable. I have brought the vehicle to a Chevrolet dealership multiple times for this issue. The dealer has replaced the rear/front camera twice and replaced a corroded cable, but the problem continues to occur. The repairs have not permanently resolved the issue. The failure happens unpredictably and makes it unsafe to reverse the vehicle, especially around pedestrians, children, or obstacles. This vehicle is equipped with a federally required backup camera, and its repeated failure presents a safety concern. The problem appears to be a recurring defect rather than normal wear, as many other Chevrolet Traverse owners have reported similar issues online. I am concerned this may indicate a broader defect affecting this model year.

Burning oil. There is something wrong. I took it to the dealership i still have warranty i really think this needs to be looked into.

The contact's son owns a 2020 Chevrolet Traverse. The contact stated that while driving at various speeds, the vehicle made an abnormal rattling sound, and the check engine warning light was illuminated. The vehicle was initially taken to an independent mechanic who could not perform the repair. The contact was referred to another independent mechanic, where it was diagnosed that a crack in the catalytic converter had caused a defect within the exhaust manifold. The contact was then informed that the failure was related to Technical Service Bulletin Number: PIP5681C and was referred to the dealer for assistance. The contact had taken the vehicle to the dealer, where the contact was informed that the vehicle no longer qualified for the TSB repair due to the mileage. The manufacturer was notified of the failure and made the same assessment. The contact was then referred to the NHTSA Hotline for assistance. The vehicle had yet to be repaired. The failure mileage was approximately 90,100.

Leaking exhaust noise at start up began around 9/22/25. Noise became louder over the following week. Check engine light came on morning of 9/24/25. Immediately took it to local GM dealership for inspection. Dealership first said it was a cracked front exhaust pipe at the bracket and then they called back and said rear pipe at the bracket was broken also the whole system needed to be replaced because the brackets were not separate but welded directly to the pipe. The estimate was over $1300. Dealership then said the error coded was probably because of the exhaust pipe and catalytic converter and that they require replacement. I discovered there are already recalls and special coverage for the same issue on the 2019, 2021 and 2022 year models of this vehicle. I contacted GM and they acknowledged the problem in other model years before and after but said there isn't enough complaints for this model year. This is a known problem and design flaw. This needs to be addressed by GM immediately. NONE of the welds have held on any parts of the exhaust system or the catalytic converter.

Weld on exhaust was faulty the bracket malfunction. The exhaust system has leak and rattle with exhaust noises, causing the converter fail.

The contact owns a 2020 Chevrolet Traverse. The contact stated that while driving at undisclosed speeds, there were abnormal sounds coming from the exhaust system. The contact stated that the vehicle sounded like a motorcycle. The contact stated that the check engine warning light was illuminated, and DTC: P0171 was displayed. Additionally, the contact stated that there were exhaust fumes entering the cabin of the vehicle. The contact had taken the vehicle to a local dealer, where it was diagnosed, and it was determined that there were cracks in the exhaust pipe and the catalytic converter pipe at Bank 2 and Bank 1 that needed to be replaced. The vehicle was not repaired. The contact researched online and related the failure to Technical Service Bulletin Number: PIP5681A. The contact had called the dealer to advise that there was a bulletin covering the cracks on the exhaust and the catalytic converter pipes, but was informed that the cracks on the pipes were on the wrong side and that the vehicle was not covered under warranty. The manufacturer was not informed of the failure. The failure mileage was 110,045.

Due to exhaust bracket failure where converter with muffler and side down pipe needs replaced. This was diagnosed at the Chevy dealer and appointment for repair is made. The exhaust suddenly became very loud so I took it to the dealership. There were no messages or warning lamps.

When I put my car in park and turn it off I get an error message that I need to "Shift to Park". It shows in the dash that it is in park but my radio, and lights stay on. I have to restart my car and put it in park, reverse, or neutral and try to put it in park again. I takes several try's to make the error message go away.

The car has 45,000 and started burning oil. The car is in brand new condition and well under mileage for an issue of such to be occurring. Took to car dealership where purchased and was told $8,500 fix!
