Electric Motor Electronics (EME) Module Failure

The EME module controls high-voltage power distribution for the traction battery and propulsion system. A circuit board issue can lead to a shutdown of high-voltage power, resulting in a loss of motive power. This issue has been the subject of multiple recalls. Estimated repair cost: $2,000 - $4,000.

Airbag Control Unit Software

A software defect in the driver's airbag control unit could affect its performance, particularly for unbelted occupants in frontal crashes. This was addressed via a recall (17V720000). Estimated repair cost: $0 (Recall).
