Service bulletin 24KWE

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

Safety Recall – INTERIM NOTIFICATION Parts are not currently available for this safety recall. This bulletin will be updated once repair parts are available. The right-hand shift stalk may have an improper wire harness terminal crimp within the wire harness connector. Loss of communication between the right-hand shift stalk and the transmission may result in the vehicle becoming disabled after it comes to a stop thereby increasing the risk of crash or injury. A transmission fault will appear on the dash display if communication is lost.
