NHTSA recall campaign
18V290000
What was wrong
Defect
Navistar, Inc. (Navistar) is recalling certain 2019 IC Bus CE school buses equipped with feature code 04091 (dual air brake system) and 04AZS (Antilock Brake System (ABS) with 4 channel Electronic Stability Protection (ESP)). The air supply line to the SR7 roll stability valve may have been improperly routed to the ATR6 brake control valve steer axle delivery port, when it should be connected to the ATR6 brake control valve control port.
Risk
During a stability control oversteer event when there are slippery road conditions, the parking brakes may be modulated unintentionally, potentially causing a loss of control and increasing the risk of a crash.
Manufacturer remedy
Navistar will notify owners, and dealers will reroute the SR7 roll stability valve supply line to the ATR6 brake control valve control port, free of charge. The recall began on June 12, 2018. Owners may contact Navistar customer service at 1-800-448-7825. Navistar's number for this recall is 18506.
