2006 Jeep Grand Cherokee ProblemsTemperature Blend/Recirculation Doors May Fail and Cause AC Problems
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.
Electrical contacts in the tail lamp housing tend to break or melt, which can cause the brake lights to fail or work intermittently. Complete inspection of the tail light housing and bulbs is recommended before replacing any parts.
Failure in the blower motor power module (automatic temperature controls) or resistor block (manual AC) may cause the heater blower motor to work only on the high setting. The connector to the power module/resistor block is known to overheat (and sometimes melt). The connector or terminals should be replaced; a replacement connector is available.

2006 Jeep Grand Cherokee RecallsThe Engine May Turn Off Unexpectedly
While operating the vehicle the driver may hit the ignition key with their knee, accidentally moving the key out of the run position. If this were to occur the engine would turn off, affecting various safety systems and increasing the risk of a crash and/or personal injury. As of this writing, the remedy for this recall is still under development.
The 4-wheel drive transfer case can direct engine power to the rear wheels only, all four wheels, or in its neutral position, non at all. These vehicles are being recalled because the transfer case can shift into its neutral position without warning. If this were to occur, engine power would not reach any of the drive wheels and the vehicle could not move under its own power. Dealers will reprogram the final drive controller which governs the transfer case to correct this concern.
Chrysler has recalled 2006-2007 Jeep Commanders and 2006 Jeep Grand Cherokees because the software programmed into the ABS electronic control module may allow a momentary delay in braking when coasting up a hill during certain conditions. This may cause a crash. Dealers will reprogram the ABS electronic control module with new software.
