The recall affects more than 1,000 trucks that were manufactured between February 2007 and May 2010. A seal on the fuel cap assembly of the dual-fill gas tanks in these vehicles were made with hose material that was not in compliance with design specifications. This hose material can deteriorate and possibly result in a fuel leak, which can pose a serious vehicle fire hazard.

A trailer brake problem prompted Navistar, Inc., to recall 2009 and 2010 models of its International LoneStar and ProStar semi trucks, according to the National Highway Traffic Safety Administration (NHTSA). The semi truck recall involves 1,437 International ProStar and LoneStar trucks that are equipped with feature code 04AZT roll stability control (RSC) system.

The RSC system is an electronic safety system that involves sensors that detect potential rollover situations, and automatically apply brakes to avoid a rollover. An air line may have been connected incorrectly on the recalled trucks, which affects air modulation to the trailer brakes if the RSC system is activated during a roll stability event. According to the NHTSA:

“LESS THAN OPTIMAL RSC CONTROL OF THE TRAILER BRAKES DURING A ROLL STABILITY EVENT MAY INCREASE THE RISK OF A CRASH WHICH CAN RESULT IN PROPERTY DAMAGE, PERSONAL INJURY, OR DEATH.”

Dealers will inspect and fix the air line that may be incorrectly connected at no charge.
