NHTSA recall 21V978000

What's wrong: Affects vehicles equipped with all wheel drive (awd). The bolts that attach the rear driveshaft to the transfer case may become loose or damaged, which can result in separation of the driveshaft from the transfer case.

Why it matters: Driveshaft separation can result in a loss of drive power, or unintended movement while parked if the parking brake is not engaged, increasing the risk of a crash.

The fix: Dealers will inspect and replace the driveshaft bolts. If any loose bolts are found, the driveshaft, attachment hardware, transfer case flange kit, and seal will also be replaced. Repairs will be performed free of charge. Owner notification letters were mailed February 4, 2022.
