- 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 CL 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
- Lap and shoulder seat belt arrangement for fixed (non-suspension) seats does not meet the seat belt loading requirements of fmvss 210. The inboard clinch nut in cab sill, where the buckle for the shoulder and lap belt is mounted, pulled out of the sill during the tests. Consequence of defect: if seat belt anchirage fails, the seat occupant faces an increased risk of injury in an accident or sudden stop.
- The fix
- Relocate the inboard seat belt mounting from top of the sill to the forward flange of the sill on the cab floor, and add a 3mm fillet weld around the 2 inboard clinch nuts.
