International Prostar Recall 15V607: Trailer May Detach from Truck Due to Faulty Fifth Wheel Lock

NHTSA campaign 15V607, reported September 29, 2015, 3,776 vehicles potentially affected.

What this recall means for you

Certain International ProStar, LoneStar, and TranStar trucks built between 2010 and 2013 have Fontaine Ultra LT fifth wheel connectors. Cumulative damage to the fifth wheel and its locking mechanism can cause the lock to fail to operate or fail to properly engage.

If the damage is severe enough, the trailer may unexpectedly detach from the tractor while driving, which increases the risk of a crash.

The remedy is free. Fontaine dealers will replace the fifth wheel with an Ultra NT model. Owners will be notified by Navistar, or you can contact Navistar customer service at 1-800-448-7825 or Fontaine customer service at 1-844-597-7393. You can also check your VIN for open recalls.
