NHTSA complaint #11560383

Owner complaint summary

A known defect that was previously addressed in a previous recall on the 2019 model year is still occurring on 2022 Buick Enclaves with no repair offered by GM. The defect causes a large hole to form in the exhaust pipe between the exhaust manifold and the muffler which could leak Carbon Monoxide into the passenger compartment and cause decreased engine performance. In the attached pictures the defect hole noted in the recall exactly matches the hole in the 2 pictures of the underside of my car in the exact same spot is the previous recall identified. It’s obvious that GM is still producing defective components and parts and placing them on their vehicles after a recall had caused repairs to previous model years.
