Some units of the 2021 Buick Enclave may develop a condition wherein the front exhaust pipe will be damaged after separating from the mounting bracket. For customers who own a 2021 Buick Enclave affected by this condition, GM is now issuing a new Special Coverage program that will cover repairs for the front exhaust pipe issue. In addition, customers who have already addressed the issue with a repair may be reimbursed for the repair costs.
The new Special Coverage program (N222385510) is only applicable to the 2021 model year of the Buick Enclave, and covers a condition wherein the mounting bracket on the crossover’s front exhaust pipe is separated from the pipe. As a result of this condition, a hole may form in the exhaust pipe around the bracket location, resulting in rattling or increased exhaust noise.
To address the issue, a GM technician will install a new exhaust front intermediate pipe, plus a new catalytic converter that is attached to the front exhaust pipe gasket. Dealerships are instructed to replace the front exhaust pipe as needed, while repairs are to be performed free of charge for the customer.
The Special Coverage program will cover the 2021 Buick Enclave front exhaust pipe issue for a period of 15 years or 150,000 miles, whichever occurs first as determined from the day the vehicle was originally placed in service, regardless of ownership. Furthermore, customers who own an eligible vehicle and repaired the front exhaust pipe condition prior to the release of this new Special Coverage program may be eligible to receive reimbursement of any reasonable and customary expenses related to the repair. The reimbursement provided via the Special Coverage program is intended for GM customer satisfaction, and as such, customers may not assign reimbursement claims or any other rights granted by the Special Coverage program to any third-party.
As a reminder, the 2021 Buick Enclave is equipped with the naturally aspirated 3.6 L LFY V6 gasoline engine, with the GM C1 platform serving as the underlying architecture. Production took place at the GM Lansing Delta Township plant in Michigan.

This sounds similar to my 2019 Equinox with 44K mi on it. The experts blamed the noise on a bent heat shield, straightened it out from striking the exhaust system and told me it is all quiet. Of course this was on my dime and the noise persists.
Should of bought a Toyota.
Instead you chose to be a foolish consumer and buy a GM.
Gm backing a know problem, how about backing the 8 speed transmission for 15 yrs and 150,000 and u will win some loyal supporters.
My enclace had the recent work completed and the dealership said the drivers side exhaust pipe is covered under this special program coverage and I am responsible for paying to replace the passenger side exhaust line…. how does this make sense?
My vehicle has been affected by this. I noticed a small sound of the noise from the exhaust. Took it to the dealership and they found nothing. a couple of years I hear a loud sound from vehicle, take it to the dealership and now I need and exhaust pipe. Sadly there’s none in the country to replace it with. My vehicle sounds awful. I am planning to go out of town and can’t drive my vehicle. The dealership wants to charge me $285 to weld the old part to my vehicle as a fix. This is absurd. Buick Enclave was my dream vehicle, but since I purchased it new, I had rubbing brakes which they had to replace with squeaking brake and this happens. I’m so disgusted with this vehicle.
Bring the dealership a copy of this article. They will not charge for the repair. But keep in mind that it can happen again, read my post, back in the dealership with the same issue after a year.
My exhaust was repaired last year after two trips to the dealer to determine the problem. The issue was only found after I pulled this article. Yesterday I dropped my car off again for the same problem. The dealership just confirmed that it is the same exact issue. Now my question is, will this completely fix the issue. Each time this problem occurs, it causes compression issues which in turn is causing damage to the transmission and engine head. What is GM to do for the reoccurring problem? Yes, this is being fixed free of charge, but this is the second repair. How many more times do I have to return befor serious issues begin?
