Known issues on the 1989 90. Two recalls are on federal record for this model year. The first covers the transaxle's power train and axle assembly: differential oil is lost over time to evaporation, and the resulting low oil level causes premature bearing and gear wear that can make the drive wheels lose power or the front wheels lock, risking rapid deceleration and loss of vehicle control. The second covers the frontal air bag sensor and control module, which can fail to meet durability standards over the vehicle's lifetime and inadvertently deploy the air bag restraint system without warning, risking loss of vehicle control. No complaints or technical service bulletins are logged for the year. The factory diagnostic and repair procedures behind both systems are here.
Whether it's a differential oil check on the transaxle or inspecting the air bag sensor wiring, it keeps you on the OEM procedure and the correct specification for your specific 1989 90.
