Heater core leaks are common in this model, more so if the wrong anti-freeze/coolant is used in the cooling system.

Reverse gear failures and noise in the manual transmission models are common.

One or both head lights may not work due to premature head light bulb burnout and/or bulb harness failure. Care should be taken to inspect the head light harness connector for damage when replacing bulbs. Damaged connectors should be replaced.
