Chrysler reportedly says, "Both events occurred infrequently and appeared to resolve themselves by tuning the vehicle's ignition off and then on."
Engineers discovered a problem with the anti-lock-braking system software that causes the instrument cluster display of the Grand Cherokee to illuminate warning lights and black out - even its ABS and electronic stability control systems are affected. To fix the Jeeps, Chrysler will update the vehicle's software.
The Ram trucks' instrument clusters have faulty digital memory that prevented the displays from activating correctly. Chrysler will perform an instrument cluster software update to fix them, and most of the trucks still are in dealership possession.
No injuries in relation to the recalls have been reported. Chrysler will provide the software updates to customers free of charge.
