Service campaign 24B66

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

In some of the affected vehicles, it is possible the required software required for the Pro Trailer Backup Assist (PTBA) feature was not installed in the vehicle during assembly. A customer with a vehicle that did not receive the required software will be unable to complete the trailer calibration process required to use the PTBA feature. Trailer maneuvering using the steering wheel will be unaffected

The document

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
