Has your Autocar been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Autocar dealer can also check your VIN. Recall repairs are free.

Engine and engine cooling › Engine

Summary
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.
Consequence
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.
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.

May 8, 2013NHTSA 13V18400082 vehicles potentially affected

Service brakes, air

Summary
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."
Consequence
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.
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.

February 19, 2009NHTSA 09V060000690 vehicles potentially affected

Parking brake › Driveline › Air

Summary
Autocar is recalling 690 my 2008-2009 acx, wx and wxll heavy duty class 8 vehicles equipped with quick release valves (qrv). There are qrv's in two areas of the vehicle. The first is in the lift axle air lines. A leak in that qrv would affect the rate at which the tag/pusher axle is lowered/lifted. The second is in the park brake air lines. A leak in that qrv would release pressure on the park brake springs; if the lead is large enough, the pressure will drop and set the brakes on the rear axle.
Consequence
Drivers would not be aware of brake system failure and braking capability would not be possible, increasing the risk of a crash.
Remedy
Autocar will notify owners and provide instructions for scheduling repair of the vehicle at an authorized autocar service facility, at no cost to the vehicle's owner. The recall began on April 9, 2009. Owners may contact autocar at 1-765-489-5499.

Steering › Gear box › Shaft sector

Summary

Steering

Summary
Autocar is recalling 7 my 2008 acx chassis assemblies which were sold to grove U.S. LLC. Grove converts these chassis into cranes. The telescopic steering shaft between the in-cab tilt steer gearbox components and the floor-mounted steering gearbox is too long, and one of the pinch bolts on the shaft may not be secured properly.
Consequence
Insufficient torque on the fastener that clamps the assemblies together could result in a loss of steering control, increasing the risk of a crash.
Remedy
Autocar is working with grove to have the chassis inspected and will replace the necessary components free of charge. Owners may contact autocar at 1-765-489-6001.
