2018 CHEVROLET TRAVERSE Complaints

I currently own a 2018 Chevrolet Traverse with 63k miles the had a cracked catalytic converter. The catalytic converter was replaced but the dealer also charged me for a flex pipe replacement which they said was broken too. This is a known issue as per GM's own bulletin #PIP5681, yet they refused to cover the repair in it's entirety. GM is entirely covering this issue in 2018-2021 chevy traverse vehicles, but they are refusing to cover the costs of the flex pipe replacement for approximately $600.

The exhaust system mount bracket broken allowing exhaust system movement resulting in a cracked catalytic converter . The mount bracket broke due to a poor weld from the part supplier. The repair cost $2404.74 on 6/5/2023 at 33.953 miles . Recently I researched this issue and found GM policy # N212356540 on 2019 Chevrolet Traverse and Buick Enclave with exact same issue with coverage to 150,000 miles. My research also found that many other owners of 2018 Traverse complaining about the exact same issue with very similar costs. This obvious emission item should have been covered. l

My vehicle was getting a check engine code #P0420, took to my GM dealer for service on [XXX]. RK Chevrolet in Virginia Beach, VA. Was told the error was caused by the mounting bracket on the front exhaust pipe had separated from the pipe, resulting in a hole in the pipe. They replaced the front exhaust pipe (85542639) and 2 pipe gaskets (84135650) as well as the muffler section of the exhaust. GM has issued a special coverage [XXX] on the 2021 Traverse for these exact part numbers, and are replacing at no cost. But if the same part numbers are failing on the 2018 (and probably 2019 and 2020) shouldn't they be covering all models with these parts.

The rear catalytic converter has a crack in it which causes exhaust fumes to blow right into the cab of the vehicle. I have called and reported. I asked if there was a recall, chevy said theres no recalls. I stated how bad the fumes are and that when quoted, it is over 2000.00 to repair. I have looked into this and it seems to be a common issue with the Traverse. Muffler shops and regular mechanics refuse to touch this issue and state it has to be taken to a dealership for replacement and repairs. I currently cannot transport my children in the vehicle. I drive 10 miles to work and have a headache all day due to the fumes i injest in the drive to work. By the time i get to work i am very light headed and dizzy. This is a serious issue that needs to be addressed and taken seriously before any fatalities due to the lack of concern or care from Chevrolet.

The contact owns a 2018 Chevrolet Traverse. The contact stated that while driving at an undisclosed speed, the exhaust system failed. The contact stated that the exhaust system was extremely loud. The vehicle was taken to an independent mechanic where it was diagnosed with a failed exhaust system and the exhaust system needed to be replaced. The vehicle was repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 30,000.

Catalytic converter failed, 3rd time in 2 years. Vehicle began losing power while on interstate. Issue has been confirmed by dealership inspection. Issue has been claimed by many other owners of this make and model but no recalls issued or warranty coverage for known issue. Check engine light came on just as issue began while driving with my family.

I shift into Park, then turn the car off and the dash starts dinging stating" shift to park" You then have to shove the gear up to get it to park all the way.

I had just got gas and the vehicle took longer than usual to start/turn over. I was leaving the store and sitting at the stop sign that is on a small incline. When I proceeded to go, my truck shook a few times, cut off, and I had no control of the vehicle. The brake pedal would not push down and my vehicle began rolling backwards. There was a car behind me that started honking his horn because I was going to run into him. I pushed the start/turn off ignition button and tried the brakes again and it worked. I had to sit there for about 5 minutes to get myself together because I was terrified to take off again. About a week later I was pulling out from my subdivision and the truck started alarming to service the StabiliTrak as I was pulling out. At the moment, the steering wheel became almost impossible to turn and the car didn't want to go! I had several cars coming my way and my vehicle was in the middle of the road. Thank goodness the cars slowed down and my vehicle decided to start working. About a month later it started sounding like a go-kart. I had the vehicle checked out by a mechanic and I was told I needed a new battery and my exhaust pipe had a hole. I bought the battery and the $1200 pipe and had it installed. Now a different exhaust pipe has a hole and the part is on back order because apparently this is a frequent reccuring issue but no recall. I never feel safe driving my truck and it is a 2018 and not yet at 100,000 miles, That is pretty sad! The vehicle is available for inspection.

On Saturday December 16, 2023, I drove to Best Buy in Beaumont, Texas to pick up my son’s Christmas gift. I am inside for about 30 or so shopping around. When I get back to my car I notice my back moon roof was completely shattered. Only tiny particles of glass fell in my vehicle but I notice the middle of the glass was pushed up a little higher like something happened to it from the inside.

The car shifter doesn't detect that it's parked and keeps displaying "Shift to Park" message not allowing you to turn off the car completely. This problem happened before and was only fixed by replacing the shifter but it happens again after about the same time driving the original shifter.
