What this means for you
Our assessment, not the agency’s: severity 4/5 (Severe).
The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.
Our severity reasoning: The recall involves a structural vehicle defect (hub carrier cracking/failure) that could result in loss of vehicle control and a crash, meeting the criteria for a Severe rating.
Plain-English summary
ZF Group North America Operations is recalling certain Hub Carriers manufactured between January 17, 2014, and June 1, 2015. The recall addresses casting problems that may result in areas of porosity within the hub carriers. These defects can cause the components to leak oil or crack.
Cracks in the hub may lead to hub failure, which could cause a loss of vehicle control and increase the risk of a crash. ZF has notified the affected bus manufacturers to initiate a routine inspection process to identify any hub carrier leaks.
When parts become available, the affected hub carriers will be replaced free of charge. Owners may contact ZF customer service at 1-734-416-6200 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236 for more information.
