- Summary
- On certain trucks equipped with manifold dash valves with push to connect fittings used to control the park brake function on trucks and trailers with air brakes, the park knob can pop out unexpectedly while the vehicle is in motion. This will exhaust the air from the park brake system on the trailer and apply the parking brakes.
- Consequence
- If this condition is not noticed, the driver could lose control of the vehicle, possibly resulting in a vehicle crash.
- Remedy
- Haldex has notified its customers to make arrangements to have the valve inspected and, if necessary, replaced free of charge. Owner notification is expected to begin during January 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact haldex brake systems at 816-801-2641 or mack at 1-610-709-3337.
- Notes
- Also, customers can contact the national highway traffic safety administration's auto safety hotline at 1-888-dash-2-dot (1-888-327-4236).

Has your Mack been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Mack dealer can also check your VIN. Recall repairs are free.
