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.
