2001 Mack MR recalls 3
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
- On certain chassis built with lng engines, the nexgen lng tank's primary and secondary relief valves could fail to open and relieve tank pressure.
- The risk
- This could cause ice buildup on the discharge side of the primary and secondary pressure system allowing the relief system to freeze and become blocked resulting in over pressurization of the lng tanks creating the risk of catastrophic tank rupture which could cause serious injury or death.
- The fix
- Dealers will retrofit the lng tanks with a new primary relief valve pipe away tube and a new ventilated shroud. The recall began april 6, 2004. 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 mack at 1-610-709-3337.
- The problem
- Vehicle description: heavy duty trucks 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.
- The risk
- 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.
- The fix
- Dealers will replace these valves. Owner notification began november 16, 2001. 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 mack at 1-610-709-3011 or meritor wabco at 800-535-5560.
