- Summary
- On certain terminal tractors built with a steerable auxiliary axle and equipped with certain meritor-wabco brake system two and four port relay valves, the valve may stick open when a high-pressure application is released.
- Consequence
- When the valve sticks open, it can result in a total loss of air from either the service or the park brake system. The driver may lose braking ability under a service application, possibly resulting in a vehicle crash.
- Remedy
- Dealers will replace these valves. Meritor wabco is conducting the owner notification and remedy for this campaign. 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 meritor wabco at 800-535-5560 or kalmar at 903-759-5490.
- Notes
- Also contact the national highway traffic safety administration's auto safety hotline at 1-888-dash-2-dot (1-888-327-4236).

Has your Magnum 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 Magnum dealer can also check your VIN. Recall repairs are free.
