The door ajar light may illuminate and chime during driving, even when the sliding door is closed. Often, this is caused by a faulty switch in the C-pillar; a revised switch is available.
Voltage spikes can cause erratic behavior in the electrical system (lights, locks, wipers, head lamps). This is often caused by relays. Inspection and replacement of relays is required; revised relays are available.
The airbag warning light may remain illuminated while the ignition switch is in the "on" position. This can be caused by water that has entered into the airbag six-way connector in the engine compartment.
Sometimes the vent windows' latch can pop open; if it will not stay closed or rattles, the latch assembly should be replaced.
Carbon buildup on the top of the piston is common. Over time this can lead to symptoms varying from light ticking to knocking noises. Performing a fuel injector cleaning procedure can often help the condition by removing some of the piston top deposits.
The rear lift gate support (prop) attaching bolts may break, causing the lift gate to fall unexpectedly. Thorough inspection of the bolts is required; if the support washers are loose, the supports need to be replaced.
A problem with the sliding door track and door stops can allow the door to slide out of the track and fall off the vehicle. This is more common when doors are opened fast and allowed to hit the stops with a lot of force.
Triggered by a short in the rear wiper motor/circuit (which causes a fuse to blow), the airbag warning light can illuminate erroneously.
