Jeep Grand Cherokee ProblemsFront and Rear Differential Pinion Seal and Transfer Case Leaks
Leaks at the front and/or rear differential pinion seal and from the transfer case are common. Leakage from the transfer case normally occurs at the case-mating surfaces and require removal of the transfer case to reseal.
A no crank or no start condition may develop due to electronic lockup of the wireless control module (WCM), also referred to as the Sentry Key Remote Entry Module (SKREEM). When this module fails the remote keyless entry system will also not operate. The WCM is commonly replaced to correct this concern.
Temperature blend and recirculation doors commonly fail, which can cause the AC modes not to change or the temperature to be different on the left and right sides. If replacing blend air doors, a recirculation door, a door link, or a sub-assembly housing, new heating, ventilation and AC (HVAC) sub-assemblies are available that improve reliability.

Jeep Grand Cherokee RecallsTransmission Shift Lever Lock Malfunctions
The transmission shift lever may lock in the park or neutral position when the vehicle comes to a stop due to a electrical connection failure at the brake transmission shift lock solenoid. Dealers will replace the shift lever assembly free of charge to resolve the concern.
The vehicle may not notify the occupants that the vehicle is not shifted to the park position when a door is opened, resulting in an occupant not knowing that the vehicle is not secured in park, the vehicle possibly rolling away and risking injury. Dealers will update the vehicle software to mitigate the risk of vehicle roll-away free of charge to resolve the concern.
The left front brake caliper could crack because the materials used in manufacturing it were incorrect. Dealers will inspect and replace affected left front brake calipers depending on the casting date listed on them free of charge to resolve the concern.
