Recalls, owner-reported complaints, investigations and safety data

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.
0
Safety recallsA 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.

InvestigationsNHTSA 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.

Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

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.

VISIBILITY/WIPER

May 8, 2013
797 units potentially affected
The defect: Autocar, LLC is recalling certain model year 2012-2013 ACX trucks built May 1, 2012, through November 15, 2012. Due to an insufficient weld, the windshield wiper arms of the vehicles may not be held in their proper position. Thus, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 104, "Windshield wiping and washing systems."
The risk: Without properly working windshield wipers, the driver's vision could be hindered by precipitation, 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 July 19, 2013. Owners may contact Autocar at 1-765-489-5499. Autocar's recall campaign number is A-1303.

Safety investigations

NHTSA inquiries naming this vehicle. An investigation is not a finding of a defect.

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

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
