Chronology :
On August 16, 2022, Carrier received notification of a thermal incident involving a Supra S6 TRU in Aurora, CO.
On September 14, 2022, a field inspection was conducted, with an independent third-party fire investigator, into potential causes of the thermal event.
On September 20, 2022, a production line inspection showed that the affected TRU’s wire harness was missing the heat shrinks, such that the exposed wires in the harness may come into contact with surrounding metal or other exposed wires.
As a result, all shipments of affected TRUs were put on hold on September 22, 2022, and Carrier immediately began a careful analysis of the affected TRU’s wire harness to assess the potential product safety risk.
To date there has been only the one thermal event related to this issue, and no other field reports of arcing.
After much internal analysis and discussion with safety engineers, on October 20, 2022, Carrier determined that the issue presented a potential safety-related defect reportable to NHTSA under Part 573. That same business day, on October 20, 2022, Carrier filed this 573 Defect and Non-Compliance Report.

Dear Valued Customer:
This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act.
Carrier Transicold has decided that a defect which relates to motor vehicle safety exists in Supra series S6, S7, S8, S9 and S10 diesel truck refrigeration units (together, the “affected TRUs”). Our records indicate that affected TRUs are registered to your company under the serial number(s) listed in the attachment to this letter.
This is a safety recall notice under the National Traffic and Motor Vehicle Safety Act. Failure to perform the inspection and installation work described in this letter as soon as possible could result in property damage or personal injury.
The 12-volt wire harness, used for the fuel heat option within the affected TRUs, may be exposed and missing heat shrink. The exposed, energized 12-volt wires, can, under certain conditions, lead to electrical arcing and possibly a fire.
Your authorized Carrier Transicold dealer will contact you to arrange to have all affected TRUs shown in the attachment to this letter or otherwise in your possession inspected. The inspection and rework will be provided at no charge to you. During that inspection, the dealer will straight cut any exposed wires in the harness, apply new heat shrink for some wires, add a connector to the remaining wires, and remove a fuse. The inspection and securing of an affected TRU’s 12-volt harness will take approximately 1.5 hours.
Carrier Transicold dealers have also received notice that the defect is present, and that the affected TRUs’ 12-volt harness should be inspected and reworked. If your Carrier Transicold dealer has already completed this inspection and rework in accordance with this notice, no further action is required. If you are unsure whether this occurred, please confirm with your dealer as soon as possible. If you believe you have previously completed the remedy work described in this notification letter and such work was not covered by the manufacturer’s
2
warranty, or you otherwise were obligated to pay for such work, please contact your dealer for reimbursement, if appropriate. Should you need help locating an authorized Carrier Transicold dealer in your area, wish to confirm whether your Carrier Transicold equipment is affected by this notice or have any other questions, please call the Carrier Transicold Action Line at 800-448-1661.
Federal law requires any lessor who receives a notification of a determination of a safety-related defect or noncompliance pertaining to any leased motor vehicle shall send the notice to the lessee within 10 days.
If you believe that Carrier Transicold has failed to remedy the defect without charge, or if you believe that Carrier Transicold has failed to remedy the defect (without charge) within sixty (60) days of your first attempt to obtain the repair, you may submit a complaint to the Administrator, National Highway Traffic Safety Administration, 1200 New Jersey Avenue SE, Washington, DC 20590, or call the toll-free Vehicle Safety Hotline at 1-888-327-4236 (TTY: 1800-424-9153), or go to http://www.safercar.gov.

Country : United States Chronology :
On August 16, 2022, Carrier received notification of a thermal incident involving a Supra S6 TRU in Aurora, CO. On September 14, 2022, a field inspection was conducted, with an independent third-party fire investigator, into potential causes of the thermal event. On September 20, 2022, a production line inspection showed that the affected TRU’s wire harness was missing the heat shrinks, such that the exposed wires in the harness may come into contact with surrounding metal or other exposed wires. As a result, all shipments of affected TRUs were put on hold on September 22, 2022, and Carrier immediately began a careful analysis of the affected TRU’s wire harness to assess the potential product safety risk. To date there has been only the one thermal event related to this issue, and no other field reports of arcing. After much internal analysis and discussion with safety engineers, on October 20, 2022, Carrier determined that the issue presented a potential safety-related defect reportable to NHTSA under Part 573. That same business day, on October 20, 2022, Carrier filed this 573 Defect and Non-Compliance Report.
