Turn signal, Software
The Smart Junction Box (SJB) software logic may not properly interpret the signals received from the multifunction switch, which could cause the turn signal to activate in the opposite direction of what the driver intended. A turn signal that activates in the opposite direction of what was intended by the driver increases the risk of a crash.
Fix: Dealers will update the SJB software, free of charge.

Crash riskIf the anti-lock brakes malfunction, the ABS warning light stays off and only the general brake light comes on, so drivers may not know the brakes could lock up during hard braking. This raises the risk of a crash.
Fix: The dealer will update the ABS control unit software at no charge.
