DEFECT DESCRIPTION
The BCM software does not consider the absolute state of the park brake in the
auto neutral feature, resulting in the engine ramp-up during PTO operation to
overcome the park brake and possibly result in unexpected vehicle movement. A
vehicle that unexpectedly moves can increase the risk of a crash or injury.

The National Traffic and Motor Vehicle Safety Act, as amended, provides that
each vehicle that is subject to a vehicle recall campaign must be adequately
repaired within a reasonable time after the owner has tendered it for repair. A
failure to adequately repair within 60 days after a tender of a vehicle is prima
facie evidence of failure to repair within a reasonable time. If the condition is not
adequately repaired within 60 days, the owner may be entitled to replacement
with an identical or reasonable equivalent vehicle at no charge, or to a refund of
the purchase price less a reasonable allowance for depreciation.
Dealers must correct all vehicles subject to this campaign at no charge to the
owner, regardless of mileage, age of vehicle, or ownership, from this time
forward.

Dealers should proceed immediately to make necessary correction to units in
inventory. All inventory vehicles subject to this recall campaign must be
corrected prior to sale, transfer or delivery. If vehicles have been sold or
transferred and you are in receipt of Customer Notification Letters and
Authorization for Recall Service cards for those vehicles, the transfer location or
customer must be notified immediately from your dealer location.
Dealers must make every effort to promptly schedule an appointment with each
owner to repair his or her vehicle as soon as possible. However, consistent with
the customer notification, dealers are expected to complete the repairs on the
mutually agreed upon service date.
Dealers involved in the recall process will be furnished a listing of owner names
and addresses to enable them to follow up with owners and have the vehicles
corrected. Use of this listing must be limited to this campaign because the list
may contain information obtained from state motor vehicle registration records,
and the use of such motor vehicle registration data for purposes other than this
campaign is a violation of law in several states.

Country : NR Chronology :
• 01/06/2023 – Navistar Field Service receives communication from a customer that a vehicle in a cement mixer application unexpectedly moved after the engine speed was ramped up to begin pouring concrete.
• 01/12/2023 – Navistar Field Service receives a video of the incident and could not determine if this incident resulted from operator error or incorrect programming. Navistar field service arranges appointment to visit the customer location to review the vehicle.
• 01/16/2023 – Navistar Field Service inspects BCM programming and reprograms BCM software in ten units at customer location. Navistar field service could not determine if the BCM programming was altered or changed during body build by final stage manufacturer (3rd party).
• 01/18/2023 – During troubleshooting, Navistar Field Service was able to reproduce failure mode using prior BCM programming.
• 01/19/2023 through 01/30/2023 – Navistar Field Service, Engineering, and Information System (IT) personnel meet to obtain BCM software levels for all vehicles built with Auto Neutral feature to determine which vehicles had the prior 249 thru 342 BCM programming from the plant. Because the IT system was “down” this process was then performed by reviewing manual records.
• 02/07/2023 – Navistar Compliance, Field Service, and Engineering meet to discuss the failure mode and determine the impact to International trucks with the prior 249 thru 342 BCM programming. Navistar Compliance determines to elevate the issue to a Compliance Investigation and present the issue to the Navistar Compliance Committee.
• 02/14/2024 – Navistar finalizes the suspect population.
• 02/16/2023 – Navistar declares a Safety Recall. Description of Remedy :
Description of Remedy Program : • The remedy will involve updating the BCM software to the current
software that looks at absolute state of the park brake status in the auto neutral feature.
• Navistar’s plan for reimbursement of pre-notification remedies, on file with NHTSA and dated 05/06/2022, applies and reimbursement instructions will be included in the customer notification.
