Service bulletin 15803

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

15803 ? Customer Satisfaction Program. These vehicles may have a condition in which the tape from the rear axle wiring harness can unwrap and, in rare cases, become tangled in the driveshaft. If this occurs, the wiring harness could be torn away from its mounting points and connectors and wrap itself around the rotating driveshaft. Dealers are to fit cable ties to secure the tape to the rear axle wiring harness.
