2011 Autocar Acx recalls 4
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
- Autocar, LLC is recalling certain model year 2005-2013 ACX, WX, and WXLL trucks built November 16, 2004, through September 10, 2012. On the affected vehicles, the air brake systems were built without the required air tank drain valve. Therefore, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 121, "Air Brake Systems."
- The risk
- Air tanks with valves omitted will not drain if moisture is introduced into the tank, potentially reducing air capacity in the air brake system, which could cause a reduction in brake performance and equipment durability, thus increasing the risk of a crash.
- The fix
- Autocar will notify owners, and dealers will repair the vehicles free of charge. The recall began on June 27, 2013. Owners may contact Autocar at 1-765-489-5499. Autocar's recall campaign number is A-1302.
- The problem
- Autocar, LLC is recalling certain model year 2011-2013 ACX vehicles manufactured January 24, 2011, through December 4, 2012. These vehicles are equipped with Meritor axle assemblies that were built with disc brakes using MGM J24 series air brake chambers. In the affected axles, the brake chambers may leak pressure allowing the parking brake to drag when it is supposed to be released. Brake dragging could lead to overheated brake components.
- The risk
- Overheated brake components could result in a fire.
- The fix
- Autocar will notify owners and will replace the actuators as needed, free of charge. The safety recall began on June 10, 2013. Owners may contact Autocar at 1-765-489-5499. Autocar's campaign recall number is A-1301.
- The problem
- 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.
- The 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.
- The fix
- 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.
