# Service bulletin 511388

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- NHTSA id: 10199445
- Published by NHTSA: 2021\-08\-03

## NHTSA's summary

The flanged wheel lug nuts on your vehicle may have been over\-torqued during service to an incorrect torque specification in the Service \& Owner's manuals. A yielded wheel stud may eventually break, which could lead to a wheel separating from the vehicle during operation. A wheel separating from the vehicle could cause a vehicle crash without prior warning and/or the wheel/tire could pose a risk to other vehicles or pedestrians.
