2011 Autocar Acx Recalls

Safety recall campaigns filed with NHTSA that cover this model year

Recalls apply to specific vehicles, not to every vehicle of a model year. Check your VIN with NHTSA or your manufacturer's dealer to confirm whether a recall affects your vehicle.

Recall campaignsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

Recall campaigns

4 campaigns cover this model year — what the defect is, what it could cause, and what the remedy is

14V132000

ENGINE AND ENGINE COOLING:ENGINE

Mar 19, 2014
4,192 units potentially affected
The defect: Autocar, LLC (Autocar) is recalling certain model year 2008-2014 ACX, WX, and WXLL vehicles manufactured July 30, 2007, through February 10, 2014, and equipped with certain Cummins Westport Model ISL G or ISX12 G engines. Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor.
The risk: The improper operation of the sensor could induce elevated exhaust temperatures or flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to a person near the exhaust pipe.
The remedy: Cummins Inc. and Cummins Wesport Inc. will notify owners, and authorized Cummins service facilities will upload a new ECM calibration, free of charge. The recall began on April 12, 2014. Owners may contact Autocar at 1-765-489-5499 or Cummins Inc. at 1-800-343-7357. Autocar's number for this recall is A-1402.

SERVICE BRAKES, AIR

May 8, 2013
82 units potentially affected
The defect: 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 remedy: 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.

PARKING BRAKE:CONVENTIONAL:AIR

Apr 11, 2013
532 units potentially affected
The defect: 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 remedy: 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.

SERVICE BRAKES, AIR:SUPPLY:CHECK VALVE

Feb 8, 2012
269 units potentially affected
The 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.
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 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.

What a recall is

Safety recall
A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
Safety investigation
NHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
Manufacturer communication
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.

Safety investigations

PE13011ClosedPreliminary Evaluation

Delayed Throttle Response

Opened Apr 26, 2013
Closed Dec 9, 2013

This investigation was opened based on a fleet complaint alleging delayed throttle response which could potentially lead to extended stopping distances and/or increase the risk of a crash.Autocar responded to ODI's Information Request (IR) letter and provided test data including its FMVSS 124 validation data.ODI reviewed Autocar's testing procedures and results with NHTSA's Office of Vehicle Safety Compliance and Office of Rule Making.The test procedure was acceptable as were the results.In an effort to further quantify the safety risk, ODI surveyed nine fleets operating the same subject vehicles.Of the eight reporting fleets, only one expressed concerns similar to the fleet submitting the VOQ.Of all the fleets contacted, none had experienced a crash where the throttle delay was a contributing factor.Autocar provided a modified direct wire throttle to the initial fleet as a customer satisfaction campaign.This configuration resulted in an improved throttle response.In light of the low rate of delayed throttle response on the subject vehicles and Autocar's actions to improve the throttle response on the complaint vehicles, further use of agency resources does not appear to be warranted.The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.The agency reserves the right to take further action if warranted by the circumstances.The ODI complaint cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID using the following (ODI) number: 10471829
