Second occurrence of below happening, first time being 11/28/25, and most recently 11/05/25. Clutch engaged uncommanded while stopped with service brakes engaged. Truck kept trying to power through the service brakes until it was forcefully stalled out with service brakes. Truck is start-able immediately afterwards, but not drivable with engine stop warning lamp illuminated and a error message "Neutral Gear Not Secured" Nearly rear ended a stopped vehicle in front of truck, so yeah, slight safety concern of uncommanded movement of vehicle.

Mack Trucks, Inc. (Mack) is recalling certain model year 2015 and 2016 CXU and LEU trucks manufactured May 20, 2014, to March 24, 2015, equipped with certain Haldex Life Seal Type 30/30 Long Stroke Air Brake Actuators manufactured from January 9, 2014, through February 3, 2015. The affected actuators may have an incomplete attachment of the internal rubber diaphragm to the actuation mechanism of the parking brake section of the Life Seal actuator.
Consequence: If the diaphragm is not completely attached, there may be internal leakage from the service section past the diaphragm, potentially trapping air pressure in the parking brake section. This air pressure in turn, if not vented, may prevent full release of the actuator unit, and may induce brake drag and may result in overheated wheelend service brakes, increasing the risk of a fire.
Remedy: Mack will notify owners, and dealers will inspect the brake actuator and replace, as necessary, free of charge. The recall began March 20, 2015. Owners may contact Mack customer service at 1-610-709-2131. Mack's number for this recall is SC0387.

MY COWORKER WAS CHANGING THE OIL ON A 2009 MACK AND I HAPPENED TO NOTICE THAT THE 5TH WHEEL PLATE WAS SHIFTING AROUND ON THE FRAME. I APPLIED A BOX END WRENCH TO THE MOUNT BOLTS AND DISCOVERED THAT ALL TEN OF THE FASTENERS HOLDING THE 5TH WHEEL TO THE FRAME COULD BE TURNED EASILY USING ONE HAND. THAT IS NOT MY IDEA OF BEING SECURELY ATTACHED! NO ACTION WAS TAKEN ON THIS TRUCK BECAUSE IT WAS TIME TO GO HOME AND IF THE BOSS DOESN'T CARE AND MACK DOESN'T CARE WHAT CAN I DO EXCEPT COMPLAIN TO THE FEDERAL GOVERNMENT THAT MACK IS USING SUBSTANDARD BO…

SOME OF THE 2008, MANY OF THE 2009, AND ALMOST ALL OF THE 2010 MODEL MACK TRUCKS USED BY ABF FREIGHT SYSTEM WERE BUILT AND DELIVERED WITH WEAK BOLTS HOLDING THE 5TH WHEEL COUPLER TO THE FRAME. ON 27 SEPT 2010, UNIT 19212 WAS IN THE SHOP FOR ROUTINE REPAIRS. A MECHANIC NOTICED THAT ALL OF THE BOLTS ON THE RIGHT SIDE WERE LOOSE ENOUGH TO RATTLE IN THEIR HOLES AND THAT THE COUPLER WAS SLIDING AROUND ON THE FRAME. THE MANAGER INSTRUCTED US TO TIGHTEN THE BOLTS AND NOT TO REPLACE ANY UNLESS THEY STRETCHED. ALL OF THE BOLTS STRETCHED. ALL WERE REP…
ON TUESDAY, JULY 19 OF 2011, I OBSERVED THAT THE 5TH WHEEL BOLTS ON ABF UNIT NUMBER 19223 WERE LOOSE ENOUGH TO BE TURNED BY HAND. THE BOLTS ARE NOT BEING INTERFERED WITH BY THE HUCK RIVETS BELOW THEM. THE NUTS ARE PREVAILING TORQUE LOCK NUTS AND ARE NOT LOOSE ON THE BOLTS. THE BOLTS HAVE STRETCHED UNDER LOAD. I WAS GOING TO SHOW THE UNIT TO THE DIRECTOR OF MAINTENANCE, WHO HAPPENED TO BE IN OUR SHOP THAT DAY. UNFORTUNATELY, UNIT 19223 WAS SENT OUT BEFORE I COULD SHOW HIM. I DID, HOWEVER, MAKE A VIDEO OF ME TURNING THE LOOSE BOLT BY HAND. THIS I…
