Service bulletin A271214 2031145-

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

complaints are reported by the customer regarding electrical features and functions in the vehicle. One or more warning lights on in cluster. The DIS or other displays in cluster are blank. MMI does not function. Windows do not function. LED indicators in various buttons inside the vehicle do not light up. The voltage regulator on the alternator can sporadically fail causing the electrical system to experience too high of voltage. As a result, the affected vehicle electronic components go in to high voltage protection and deactivate sensitive displays and indicators to prevent electrical damage. When an over voltage condition occurs the vehicle electronics and alternator are protected, thus there is no need to replace the entire alternator assembly.
