Recall 13V184 affects 82 2005-2013 Autocar Wxll, Wx, and Acx trucks for missing air tank drain valves. Repair is free at any franchised Autocar dealer.

Autocar is recalling 82 2005-2013 Wxll, Wx, and Acx trucks because their air brake systems were built without the required air tank drain valve. Trapped moisture can reduce air capacity, brake performance, and equipment durability, which increases crash risk, and the Autocar dealer repair will be free once available.

What's wrong?

The air brake system on 2005-2013 Autocar Wxll, Wx, and Acx trucks uses compressed air to apply the service brakes. Air tanks store that compressed air so the brakes have pressure available when the driver presses the pedal. A drain valve on the tank gives a technician a controlled way to drain moisture and contamination from the system.

On affected trucks, the air brake system was built without the required air tank drain valve. The problem is not a worn or damaged valve; the required valve is missing from the brake system. That means the truck does not match the air brake safety standard that requires the tank to have a drain point.

There is no warning sign before failure. The clearest clue is found during inspection: the air tank does not have the required drain valve. If that is found, describe the missing air tank drain valve when speaking with an Autocar dealer or service shop.

Who's affected?

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific truck.

What's the safety risk?

When moisture enters an air tank that lacks the drain valve, the tank does not drain properly. That reduces air capacity in the air brake system, weakens brake performance, and reduces equipment durability, increasing the risk of a crash. Contact an Autocar dealer for recall guidance and ask whether the truck is safe to operate until service. Repair will be free at any franchised Autocar dealer once available.

What should I do?

  1. Check your VIN to confirm your 2005-2013 Autocar Wxll, Wx, or Acx truck is included in this recall.
  2. Contact a franchised Autocar dealer to schedule the free air-tank drain-valve repair.
  3. Reference recall number 13V184 when you call, and bring the recall notice if Autocar mailed one.
  4. Ask the dealer to confirm the air brake tank drain valves are installed so moisture can drain from the system.
  5. Drive with extra following distance until the repair is complete, since reduced air capacity can reduce brake performance.

What happens at the repair

At the dealer, an Autocar technician repairs the air brake system so the required air tank drain valve is present. The filing does not give a more detailed parts procedure, so the service desk should confirm the exact brake system work before the truck is brought in. The dealer repair will be free once available, with parts and labor covered under recall 13V184.
