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.

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.

(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?

I WOULD PUT THE VEHICLE IN DRIVE AND THE "D" LIGHT WOULD BLINK BUT THE CAR WOULD NOT MOVE. IN MARCH AFTER SEVERAL TRIPS TO THE DEALERSHIP THEY FINALLY REPAIRED THE VEHICLE. THEY REMOVED THE TRANSMISSION AND REPLACED A SENSOR. THE VEHICLE DID NOT HAVE ANY ISSUES UNTIL JULY 23RD WHEN DRIVING ON A CITY ROAD THE CAR GOT STUCK IN FIRST GEAR. I WAS PUSHING THE GAS PEDAL AND THE CAR WOULD NOT GO OVER 20 MPH. I TOOK THE VEHICLE IN AND THEY REPLACED THE TCM AND SOLENOID SENSOR. I PICKED UP THE VEHICLE ON 8/8 ONLY TO RETURN ON 8/15 WHEN THE CAR STALLED AND JERKED WHILE I WAS DRIVING. ON 8/16 I SPOKE WITH THE DEALERSHIP WHO INFORMED ME CHEVROLET ADVISED THEM TO CLEAR THE CODE AND RETURN THE VEHICLE TO ME. THIS IS A KNOWN ISSUE TO THEM AND THE ENGINEERING DEPARTMENT IS WORKING ON FIGURING OUT THE PROBLEM. AS OF 8/18/2019 THIS VEHICLE HAS SPENT 47 DAYS IN THE SHOP FOR REPAIRS AND HAS 10 REPAIR ORDERS.
