Service bulletin 511623B

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's summary

According to DTNA Recall 23V238: "The steer axle tie rod castle nut cotter-pin on the affected vehicles may be missing. This may cause the castle nut to back off, which might allow taper-end to displace from the steering arm. This could lead to a loss of steering response and a lack of direction control, potentially increasing the risk of a crash."
