Defect
Autocar is recalling certain model year 2011-2012 acx heavy-duty class 8 vehicles, manufactured from december 22, 2010, through december 5, 2011, and equipped with bendix atr-6 antilock traction relay valves. In extremely cold conditions, these bendix relay valves may potentially develop internal leakage. Internal leakage can lead to air pressure being delivered to affected primary or secondary brake causing continuous brake application.
Safety risk
Unexpected continuous brake application can cause the brakes to overheat and lead to a fire. Unexpected continuous brake application can cause the driver to lose control of the vehicle, increasing the risk of a crash. Also, the brakes may be applied without illuminating the brake lights, failing to give proper warning to other drivers.
Remedy
Autocar will notify owners, and dealers will provide a temporary repair until bendix develops a permanent remedy. This service will be performed free of charge. The safety recall began on august 8, 2012. Owners may contact autocar at 1-765-489-5499.
