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. …
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.
The exhaust pipe, gaskets and muffler. Yes, at times we do smell the exhaust inside the vehicle and a loud sound coming from the engine when the vehicle is in motion and on standby. Yes they were notified and are still waiting for parts to have it repaired. They advised to continue driving my car and refused to provide a rental to use during the downtime due to my 'issue' not covered by my warranty or extended warranty because my vehicle is over 36k miles. No warnings were on in the vehicle to notify me, I just noticed a weird sound as my car would start up when the vehicle is started and never stopped.
Engine started consuming oil at around 25-30k miles. Now adding 3Q between the recommened oil change period. First realized this when driving on road trip and the engine oil low warning triggered. Driving at night on a interstate - had to pull off and find a safe place to check it. Could of been stranded with an engine failure in the middle of nowhere. Dealer confirms the issue, but GM says 1Q per 2000mi is "normal" in their world. Refuses to do anything when losing 1/2 your oil every oil change internal...
