Service bulletin MC611121

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

With the introduction of the Silent Charge function, the control of the charging fan was reconfigured for its implementation. In rare cases, it is possible for the charging fan to cause voltage spikes and damage the electrical machine electronics (EME) module. If this EME damage occurs, the charging fan will run continuously as soon as the ignition is switched on.
