# Service campaign MAS005291 RU 26\-20

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

Certain Maserati vehicles listed in MODISCS\+ are involved in a Rapid Update to perform a PROXI alignment. During production, certain new model year vehicles were configured with parameters for a previous tire specification. This may cause incorrect AWD system management and illuminate the AWD System Overheated warning lamp. The warning does not indicate an AWD system malfunction; it results only from an incorrect vehicle configuration parameter. AWD system performance and functionality are not affected.
