2018 Chevrolet Traverse

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 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.

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.

“When the vehicle is in park and you try to turn it off with the start/stop button an on dash error code of ‘Shift to Park’ appears even though the vehicle is clearly in park. You are not able to turn the vehicle off. I took the vehicle in for service and was told that GM is aware of the issue, however, their engineers have not found a solution. This currently is forcing me to restart the engine, put my car in reverse, shift back in drive, try re-parking and turning it off again, repeating the process until it eventually turns off. I do not know if my car is truly in gear or not. I’m afraid that it might cause a dangerous situation.” not sure but I think the doors stay locked and I would not be able to exit in an emergency. The dealer wants to charge diagnosis and hundreds for repairs with the same faulty parts . I have 42000 mi and out of warranty I see this is a widespread problem and GM is not addressing what is a serious dangerous problem please help I have been living with this problem for the past 2 years it is getting worse I was hoping it would be recalled with a new part no for permanent fix.

I have a 2018 chevrolwt Traverse which needs repairs matching the TSB PIP5681C. This issue is on every traverse from 2018, and they have since created a special coverage to fox the issue for every vehicle from 2019 until now. One of the special coverage#'s is - N222385510. This is an emissions issue and a safety issue as the bracket that breaks actually punctures the exhaust pipe causing exhaust fumes to constantly smelled inside the cabin. There is no reason that GM is paying a special coverage on the 2019-2022 but not on the 2018 as well for the same exact parts and same manufacturing flaw.

Just started happening: on occasion, when trying to shut vehicle off, the accessory light kicks on and DIC says "SHIFT TO PARK". I have to restart the car many times and shift it from drive to park to finally get it to shut off. The issue is commonly discussed on youtube. It's the sensor/switch that tells the car it's in park. Please offer a fix.
