2018 Chevrolet Traverse

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.

N222385510, the exhaust system separated from the car. There are current recalls from GM for 2019-Current Traverse models with the exact same issue. Our 2018 has the exact same problem and our local GM dealer verified it, but they will not cover this expense. We were quoted $2,000 + for the fix, GM Customer Care has been no help.

Rough starting engine, close to stall while idle and stopped on-road. Check engine light activated. 2016 and 2017 model years of Chevrolet Traverse vehicles were recalled for this exact issue. This condition was covered in: Special Coverage Adjustment N192210240 Evaporative Emissions Purge Valve Replacement. Our experience shows that this recall may not have covered the entirety of this issue. It is ironic that we experienced this exact same problem in a 2018 Chevrolet Traverse. The GM dealership charged us >$300 to repair. The recall covering the immediately previous model year extended warranty and offered free replacement. I am reaching out to NHSTA to make them aware of the issue with the Purge Valve in the 2018 model year Traverse. I contacted GM and they were not able to help, other than stating the original recall did not cover 2018 model years. We believe that it should also cover the 2018 model year based on our experience.

On June 29, 2021 Unable to turn off vehicle/engine. Started approximately 1 week before on 2 occasions where I finally was able to shut off vehicle. I called dealership/service to get an appointment, but had to go in immediately because it would no longer turn off. Repair was not covered under warranty which was only 4 months past the 3 year warranty and mileage was only 27,637. It cost me just under $450 to repair this. Service advisor at Classic Chevy in Grapevine, TX commented that they had been seeing this problem which they diagnosed as INTERNAL SHIFTER FAULT. (A C/S SHIFT TO PARK MESSAGE COMES ON CLUSTER is noted on the repair invoice.) This was unnerving at the very least, and safety risk. Is this problem under any recall or potential recall?
