Report A Problem

The speedometer may become inoperative due to a failed vehicle speed sensor (VSS), . A failed sensor will require replacement.

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.

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.

A refrigerant leak at the rear AC expansion valve and/or AC evaporator seals may cause the rear AC not to work.

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.

Triggered by a short in the rear wiper motor/circuit (which causes a fuse to blow), the airbag warning light can illuminate erroneously.

The transmission has numerous problems; symptoms can range from shuddering to completely dying. The majority of the TSBs (service bulletins) require an overhaul of the transmission. Updated internal parts are available.  
An intermittent loss of speed control can happen soon after the transaxle input or output speed sensor has been replaced. The problem is most likely caused by bad connectors.
An improperly-seated connection on the starter (coming from the battery) may cause the engine not to crank. Plastic must be ground off the cable terminal so it can sit flat and flush.
Due to corrosion at the pivot, the driver side window wiper may fail. The pivot must be replaced.
Often caused by rust, the temperature control lever may be difficult to move. Spray an anti-rust penetrate on the lower pivot for the lever and apply lubricant to prevent future corrosion.
