Official summary
This program provides a no-cost, one-time repair (if needed) to the rear wheel knuckles for six (6) months from the Repair Order (RO) opening date for field service actions 21S32 or 21S43 provided that the RO opening date occurs on or before July 31, 2023. This is a one time repair. In some of the affected vehicles exposed to a corrosive environment where road salt is used during winter months, the rear toe link ball joint located in the rear knuckle could seize. A seized toe link ball joint could wear out and develop a knocking noise after installation of the updated toe links in the FSAs 21S
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
