- The problem
- Fuel injection system reconfiguration to comply with engine emission standards cause higher engine vibration levels which lead to early wear and complete failure of the secondary throttle return mechanism.
- The risk
- In the event the primary throttle return fails, failure of the secondary throttle return system would not provide protection against loss of throttle control.
- The fix
- A new production secondary throttle return system configuration will be installed.

1989 Mack RW recalls 2
Recall repairs are free. Your dealer fixes them whether or not you bought the car there - check your VIN at nhtsa.gov/recalls to see if yours is done. What to do
- The problem
- A tolerance mismatch in the crank assembly of the bosch windshield wiper motor could cause instantaneous separation of the crank from the linkage assembly in the left hand control arm assembly; this would make the system inoperable.
- The risk
- Wiper failure during vehicle operation could reduce driver's ability to see the road, and creates a potential for an accident.
- The fix
- REPLACE LEFT HAND CONTROL ARM LINKAGE ASSEMBLY.
