What Owners Say
"I was also told, some parts of the exhaust system were changed. No explanation as to why, but it doesn't seem very quiet."
Anonymous, IL (2021 Buick Enclave Essence 3.6-L V6)"This is a known problem with this vehicle. I have had it repaired 2-3 times. The last time the replaced most of the exhaust system with a new design"
Anonymous, TX (2021 Buick Enclave Avenir 3.6-L V6)"Recall for where the exhaust system ties into the engine. A crack appeared which caused a rattle noise. Fixed by dealer for free under GM recall program."
Anonymous, NJ (2021 Buick Enclave Essence 3.6-L V6)"Battery weakened then faded then failed because of internal plates falling apart. Key fob was useless..."

"Exhaust noise occurred about 6 months ago we had a letter from Buick but it was not a recall. We continued to drive until we could smell exhaust fumes. Took vehicle to GM Dealer and had to convince them it was too dangerous to drive. They loaned us a car and took about a week to repair due to parts shortages. Happy with the repair so far but unhappy we had to convince the service department that driving with an exhaust leak you could smell was dangerous."
