Known Problems
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.  
During turning, squeaks can come from the strut area; the strut mount assembly should be replaced.

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

Common areas for engine oil leaks include the camshaft plug, camshaft seal (sprocket end), valve cover gaskets, cylinder head gasket and distributor.

Noise coming from the front suspension can be caused by the front sway bar; the sway bar bushings should be replaced.

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.

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.

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.

Excessive smoke from the exhaust, lack of power, and a grinding or scraping noise from the turbocharger can indicate turbo failures. The most frequent cause of turbocharger failure is a lack of frequent oil changes.
