Bulletin Summary
The electrical machine electronics (EME) Printed Circuit Board (PCB) may not have been produced to specifications. In the event that the EME detects this condition it will shut down high-voltage electrical power. A shut down of high-voltage electrical power would result in a loss of propulsion increasing the risk of a crash. However the 12-volt electrical power remains functional to support power steering and braking.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
