On vehicles with airmatic suspension, the airmatic pump relay can stick, causing a dead battery, because the pump continues to operate when it should be shut off. Eventually, the pump will fail; the pump, fuse, and relay will need replacement. After parking and exiting the vehicle, the airmatic pump should only run for a few seconds before turning off. It should not come back on until the driver's door is opened.

After a heavy rain storm, the drains for the heating, ventilation and AC (HVAC) system intake can be plugged with leaves and other debris, causing a dead battery. Water fills the intake cavity and overflows into the vehicle, directly onto the blower motor and its regulator. This causes the regulator to short out and the blower motor will continue to run, despite the key being off and removed from the vehicle. Usually the carpet at the right front passenger floor will be wet too. If the carpet is saturated, the passenger seat may need to be removed to dry out the battery storage area before water or moisture reaches the relay and fuse holders. To prevent this, do not let leaves and twigs accumulate at base of windshield. If there are leaves or debris below the wiper blades, clean the area.

Bolts that connect the automatic tailgate actuator lever to the tailgate can break. The broken bolts need to be drilled out and the holes re-threaded before a new bolt can be installed. If you hear any unusual noises when raising or lowering the power tailgate, have the mounting bolts inspected to make sure they are tight so the problem can be repaired before the bolts break.
