    Fuel System, Other / Storage / Tank Assembly / Pressure Relief Devices

    Defect, in the NHTSA record
    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.
    Consequence, in the NHTSA record
    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.
    Remedy, in the NHTSA record
    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.

  2. 01V189004Received . 8,268 units.

    Service Brakes, Air / Controls, Pedals and Linkages

    Defect, in the NHTSA record
    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.
    Consequence, in the NHTSA record
    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, in the NHTSA record
    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.

    Defect, in the NHTSA record
    Vehicle description: class 8 trucks equipped with felsted electronic accelerator pedals. The return springs can break on the accelerator pedals that are equipped with stainless steel or electroplated wire return springs.
    Consequence, in the NHTSA record
    This condition could cause the pedal to go to full throttle if both return springs break, increasing the risk of a crash.
    Remedy, in the NHTSA record
    Replacement accelerator pedals equipped with return springs manufactured of music wire with one additional coil on each spring and with an organic coating, eliminating electroplating will be installed.

    Service Brakes, Air / Antilock

    Defect, in the NHTSA record
    Vehicle description: heavy duty trucks built with bendix air ABS with an ec-17 1030r electronic control unit (ECU), there have been reports of unwanted ABS activation at low speeds caused by 1) chafed ABS wheel speed sensor wires on rotating parts or 2) a damaged component at the wheel end that generates a certain type of erratic sensor signal.
    Consequence, in the NHTSA record
    This condition could cause the ABS ECU to exhaust the air at the air brake modulators for one or more of the wheels. This could result in extended braking distances and a possible crash.
    Remedy, in the NHTSA record
    Dealers will replace the ABS ECU.
