Chronology of Defect Determination
Describe the chronology of events leading up to the defect determination decision.
On January 12, 2024, Isuzu North America Corporation (INAC) QA received a report of a fire that occurred under the dash of a 2024MY F-Series in Georgia in a vehicle owned by a large fleet customer. INAC QA immediately reached out to the Isuzu Commercial Truck of America (ICTA) fleet representative and requested them to schedule a date at which an inspection of the vehicle could be performed.
On January 30, 2024, ICTA and INAC QA, together with representatives from the Fleet and the vehicle upfitter, performed a joint investigation on the subject vehicle. The conclusion reached based on the inspection was that the T harness connecting the Mobileye (passive) driver collision avoidance system to the subject vehicle’s turn signal/flasher module had caught fire. Upon further disassembly of the vehicle, the inspection participants discovered that the Mobileye camera cable which is routed under the dash was damaged by one of the dash mounting bolts and that exposed wires were present.
On February 1, 2024, ICTA issued a Field Product Report (FPR) for the subject vehicle in Georgia describing the damage found.
On February 1, 2024, INAC QA met internally and began reviewing the inspection photos from the subject vehicle in Georgia, the returned T harness, and the Mobileye and vehicle circuitry, along with past field data related to any Mobileye system issues. INAC QA reviewed a report from the same fleet regarding a fire that occurred in September 2023 in an F-Series vehicle equipped with a Port-installed Mobileye system. Although that fire was originally determined to be of unknown origin, upon re-review, INAC QA concluded that the Florida case and Georgia cases may have been related to the same root cause.
Between February 5, 2024, and February 7, 2024, the Fleet completed the inspection all 18 of its F-Series vehicles at its Georgia location. The Fleet reported to ICTA that 3 additional vehicles were found to have damaged Mobileye camera cables, and that the damage location was the same as the subject vehicle. Including the subject vehicle, the results indicated that 4 out of 18 (or 22%) of the vehicles at the Georgia location had camera cables that had been damaged by the dash or dash mounting bolt.
On February 6, 2024, INAC QA met with engineers from Isuzu Technical Center of America (ITCA) to review the cable routing and installation process. During this visit, INAC QA retrained the Port Installed Option (PIO) staff and informed them of the importance of ensuring the camera cable was properly positioned under the dash.
On February 8, 2024, INAC QA notified Isuzu Motors Limited (IML) about the subject vehicle in Georgia, describing the damage found.
Between February 1, 2024, and February 12, 2024, INAC QA completed the analysis of the field data and found there were a total of 11 vehicles which had cases of pinched or damaged camera cables (including the Georgia and Florida cases discussed above), with 4 resulting in fire or thermal damage. Review of the available photos from the cases also supported the conclusion that the diodes were being burned in the T harness.
On February 13, 2024, INAC QA performed an on-vehicle test and was able to induce a flame within 31 minutes.
On February 19, 2024, INAC QA finalized the review of the current field cases.
Although Isuzu is not aware of any crashes, injuries or deaths associated with this issue, on February 21, 2024, Isuzu made a decision to conduct a safety recall to address this concern. Isuzu has received 5 warranty claims that could be related to this issue.

STOP SALE AND DELIVERY – SAFETY RECALL
Date: February 28, 2024
Subject: Stop Sale and Delivery for Upcoming Safety Recall
Affected Models:
•
Certain 2019-2024MY F-Series vehicles equipped with RPO Code I4V Mobileye Collision Warning System
To: Isuzu Dealer Principal, Sales Manager and Service Manager
Effective immediately, stop the sale and delivery of affected vehicles in your inventory, even if a customer has purchased an affected vehicle. We are in the process of taking steps to address a safety related defect in these vehicles. Federal law prohibits the sale and delivery to customers of any vehicle containing a safety defect. You must not deliver any covered vehicles to customers until after the vehicle has been remedied.
WHAT IS THE CONDITION?
Isuzu Motors Limited has decided that a defect, which relates to motor vehicle safety, exists in certain 2019-2024MY F-Series vehicles equipped with RPO Code I4V Mobileye Collision Warning System. In the affected vehicles, the Mobileye camera cable extends from the centrally mounted windshield camera to the left A-pillar of the vehicle. In some of the subject vehicles, the Mobileye camera cable was installed in a manner that allowed the cable to become damaged. In the event the camera cable is damaged, the potential exists for the turn signal indicator wire, in the cable, to become grounded to the vehicle cab. If this condition occurs, when using the turn signal(s) or hazard lights, up to 15 amps of unexpected current can flow into this circuit. This will result in a buildup of heat within two diodes in the T-harness located under the left side of the dash. Continued operation of the turn signal(s) or hazard lights results in gradual failure of the diode(s). The diode(s) can become hot enough to ignite the T-harness insulating material, resulting in a fire.
WHAT WE WILL DO
We are in the process of preparing a service procedure and procuring parts to remedy these vehicles. You will receive another notice regarding owner notification and campaign bulletin release as soon as the schedule is available.
WHAT YOU SHOULD DO
Confirm the affected vehicles in dealer inventory, open a repair order referencing this Stop Sale and hold the vehicles until further notification is received.
We regret any inconvenience this action may cause you.
Sincerely,
Isuzu Commercial Truck of America, Inc.

Description of the Defect : In the affected vehicles, the Mobileye camera cable extends from the centrally mounted windshield camera to the left A-pillar of the vehicle. In some of the subject vehicles, the Mobileye camera cable was installed in a manner that allowed the cable to become damaged either by the dash mounting bolts, the steel dash support bracket or by the dash itself. In the event the camera cable is damaged, the potential exists for the turn signal indicator wire, in the cable, to become grounded to the vehicle cab. If this condition occurs, when using the turn signal(s) or hazard lights, up to 15 amps of unexpected current can flow into this circuit. This will result in a buildup of heat within two diodes in the T- harness located under the left side of the dash. Continued operation of the turn signal(s) or hazard lights results in gradual failure of the diode(s) due to excess current. The diode(s) can become hot enough to ignite the T-harness insulating material, resulting in a fire.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : If the turn signal indicator wire in the Mobileye camera cable is grounded,
one or more of the following events could occur – in each case, increasing the risk of a fire or crash:
• The hazard lights may illuminate when the driver applies either the The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 24V-157 Page 3 left or right turn signal.
• The turn signals and hazard lights may not function when the driver applies them.
• The Mobileye system may cease to function and display an error code, or no longer provide the driver with any collision avoidance information on the display.
• Smoke or fire may occur under the left side of the dash.
Description of the Cause : During installation of the Mobileye camera cable some workers inadvertently misrouted the cable; if misrouted, the cable can become damaged by the dash or upper dash bolts during the dash reinstallation. For vehicles with properly routed cables, no defect exists. Identification of Any Warning
that can Occur : • The activation of the vehicle’s hazard lights, when either the left or right turn signal is activated.
• The turn signal or hazard lights will not activate due to a failed F-26 15- amp fuse.
• An error code displayed on the Mobileye display, or no display shown.
• An electrical burning smell.
• Smoke from under the left side of the dash. Involved Components : Component Name 1 : Mobileye 6, Mobileye 8 Camera Cable

Description of Remedy :
Description of Remedy Program : Dealers will be required to inspect the Mobileye camera cable. If the cable
is undamaged, the dealer will reroute the cable to a revised location within the dash that does not contain any potential pinch or bolt damage points. If the turn signal indicator wire within the cable is damaged, the dealer will remove and replace the Mobileye camera cable and T-harness, then reroute the cable to the revised location. For vehicles that previously had this condition repaired which were not covered by warranty Isuzu will reimburse the customer for the cost of the repair. How Remedy Component Differs from Recalled Component : Identify How/When Recall Condition was Corrected in Production : Both components are identical and there is no defect in the component itself. The remedy involves ensuring the cable routing is changed within the dash to eliminate any potential pinch or damage points and/or replacing the parts that have been damaged as a result of the improper routing.
A Stop Ship was placed on Isuzu F-Series and Chevrolet 6500/7500XD vehicles equipped with Mobileye on February 26, 2024. All trucks processed after this have the Mobileye camera harness routed to the new approved location, which eliminates the pinch points and potential for damage from the dash bolts or dash. Recall Schedule :
Description of Recall Schedule : Isuzu and Chevrolet will notify their respective vehicle owners and
dealers of this recall. They will be informed that the recall inspection and repair will be done free of charge. Remedy parts are not available to repair vehicles that fail the inspection. Therefore, the first Owner Letter
(i) will ask owners to promptly make an appointment with their Dealer for an inspection and (ii) will inform owners that, if damage is found as a result of the improper routing, they will receive a second letter asking them to bring their vehicles back to the Dealer when replacement parts become available. The first recall owner notification is expected on or about 3/29/2024. For additional information, Isuzu owners may contact Isuzu Customer Relations at 1-866-441-9638 and Chevrolet owners may contact the GM Medium Duty Truck assistance line at 1-800-862-4389.
Planned Dealer Notification Date : FEB 28, 2024 – MAY 28, 2024
