General Motors has issued a recall in the United States for a few 2021 Chevrolet Tahoe and 2021 GMC Yukon SUVs.

The vehicles may be missing the adhesive between the two layers of the fuel tank shell due to a supplier manufacturing error. As a result, fuel could seep between the layers, resulting in a slow leakage over time, which could increase the risk of fire in the presence of an ignition source, though GM are unaware of accidents or injuries related to this condition. In certain cases, owners could notice a fuel odor near the SUV.

Only 18 units of the 2021 Tahoe and Yukon, built on August 13 and 14 last year, are included in this safety recall, and all of them are estimated to have the defect that will be corrected by GM’s authorized dealers by replacing the fuel tank. As the vehicles are under warranty, the automaker will not offer reimbursements, and the repairs will be made free of charge.

A GM engineer informed the company on January 14 of the defect after being notified by the fuel tank supplier of two leaks from fuel tanks. The supplier reviewed its manufacturing records and discovered the problem on 23 fuel tank shells, out of which 18 are believed to have been fitted to vehicles sold in the US. On February 4, GM decided to conduct a recall.

The planned owner notification program is scheduled for March 29, whereas dealers were informed at the beginning of February. The recall number for this safety campaign is N212327720, and owners can use it should they want to reach out to the Chevrolet or GMC customer service at 1-800-222-1020 or 1-800-462-8782 respectively. They can also contact the National Highway Traffic Safety Administration (NHTSA) at 1-888-327-4236.
