Recall 15V025000 — PARKING BRAKE:DRIVELINE:HYDRAULIC:ACTUATOR
| 349 vehicles affected
Defect: 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...
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.

Most Recent Complaints
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. Has not been looked at by independent shop or manafacterer, nothing has been inspected, mechanics within company vehicle is operated by currently researching into problem and waiting for stated problem to occur again. Refrencing a previous investigation here that i believe is related; PE 20-005
