## 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.
