The lug nuts on your big truck are tightened using a specific torque, but there's a mistake in the manual that could lead to them being overtightened. This could damage the wheel stud and cause the wheel to come loose.
Risk if Unfixed
If the wheel stud breaks, the wheel could separate from the hub, which would cause a serious accident, increasing the risk of a crash.
Free Fix
Your dealer will correct the manual's instructions and inspect your truck's wheel studs. If any are damaged, they'll replace them at no cost to you. You should contact your dealer now to confirm repair availability, as letters were mailed on November 30, 2021, and December 1, 2021.
