2023 Chevrolet Traverse Engine

Flex pipe issue

The contact owns a 2023 Chevrolet Traverse. The contact stated that while his wife was driving at an undisclosed speed, exhaust fumes entered the vehicle, causing her to have headaches. The vehicle was taken to the dealer, who determined that the exhaust pipe had corroded and cracked, leaking fumes through the muffler and Y-pipe. The contact was informed that the Y-pipe needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 55,000.

I am filing this complaint due to a recurring exhaust leak in the front exhaust pipe of my 2023 Chevrolet Traverse, which poses a potential safety hazard. During the vehicle’s bumper-to-bumper warranty period, Freedom Chevrolet in San Antonio replaced a leaking front exhaust pipe (receipt attached), a known issue covered by a Technical Service Bulletin (TSB) for earlier model years (2018–2022) but not for the 2023 Traverse. Less than two years later, with the vehicle now at approximately 84,000 miles, the front exhaust pipe has failed again, exhibiting the same leak issue. This recurring defect is concerning because exhaust leaks can allow carbon monoxide and other harmful gases to enter the vehicle cabin, posing a risk of poisoning or impaired driver awareness, especially during extended operation. Additionally, the issue may contribute to environmental hazards due to improper emissions control. Despite my requests for assistance from Freedom Chevrolet and GM Customer Care, I have not received a satisfactory resolution, and the repair cost falls on me as the vehicle is out of warranty. I am aware of complaints and TSBs documenting similar exhaust leak issues in Chevrolet Traverse models from 2018–2022, including a recall for the 2019 model year (NHTSA ID: N222385510), suggesting a systemic issue that may extend to the 2023 model. The lack of a TSB or recall for the 2023 Traverse leaves owners like myself vulnerable to repeated failures and safety risks.

The contact owns a 2023 Chevrolet Traverse. The contact stated that upon starting the vehicle, the engine was idling extremely loudly. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 40,000.

I was told from Dan Cummins where I bought my vehicle that there was a recall on my vehicle for the exhaust pipe, when I tried to get it fixed I was told there wasn’t. When I searched up the recall it says “yes there is a recall on 2023 Chevy traverse for the exhaust pipe” and where the parts are saying it’s recalled “ exhaust front intermediate pipe and the catalytic converter to front exhaust pipe gasket” is exactly where my hole is in my exhaust pipe. It started as a leak but has grown into a hole due to not being fixed. I tried adding photos of it and where it says there is a recall that “ Dealers will replace the front exhaust pipe on the 2023 Chevrolet Traverse at no cost to the customer” but I don’t know if they uploaded.

Vehicle shut down and stopped suddenly while driving. Twice this happened. Both times were under 20 miles per hour. Once at a railroad crossing and the other was turning onto a major roadway. Dealership can not locate the problem.

I have requested since April to have the recall fixed on my vehicle with no repairs to date. I have just been told the part is on back order but will let me know when it is available. It’s currently going on a year with no resolution for the known recall.
