What's wrong: The park rod assembly contains a park cam with inadequate surface hardness, which could lead to park disengagement or no park engagement when the lever is placed in park.

The fix: Replace park rod assembly on automatic transmissions.

Airbags Equipment recall #90E043001 · 1990 · 172,000 vehicles
What's wrong: Threaded inflator components May have been damaged during assembly which May allow components to separate when inflator receives a signal to deploy the air bag.
