Addressing the Issue of Unsecured Fuses and Steps to Take if Your Vehicle is Affected
Jeep Wrangler Plug-In Hybrid Electric vehicles (PHEV) have gained popularity for their eco-friendly features and impressive performance. However, recent reports have surfaced regarding a potential safety concern that could affect certain 2022-2023 models. The FCA Technical Safety and Regulatory Compliance (TSRC) organization has identified an issue with an unsecured fuse inside the high voltage battery, which may result in an unexpected loss of drive power.
Discovery of the Issue:
In February 2023, the FCA TSRC organization received its first report of a fuse melting in the HV battery of a 2022 Jeep Wrangler PHEV, drawing immediate attention to the matter. A subsequent incident involving another 2022 Jeep Wrangler PHEV with the same problem prompted the initiation of a comprehensive investigation.
Root Cause and Potential Impact:
The investigation revealed that an incorrect fastener used during vehicle production could increase resistance and generate excess heat at the 200 amp fuse interface. The prolonged exposure to high temperatures could cause the fuse to fail, leading to a loss of motive power. Drivers experiencing this issue might notice a Malfunction Indicator Lamp (MIL) illuminated, changes in drivability, and/or noise originating from the HV battery pack assembly.
Suspect Period and Population:
The suspect period for this issue spans from January 10, 2022, when the incorrect fasteners were introduced, to September 20, 2022, when the use of incorrect fasteners ceased. The identification of the suspect population was determined through careful examination of vehicle and supplier manufacturing records.
Recall and Resolution:
To address this safety concern, Jeep has issued a recall, known as recall number 53A by Chrysler and NHTSA campaign number 23V-303. Owners of affected vehicles will receive notifications instructing them to visit their authorized dealerships. At the dealership, the battery fuse will be inspected, and if necessary, replaced to ensure proper functionality. Additionally, the battery assembly will undergo inspection for signs of charring or discoloration on the bus bars, and if required, will be replaced as part of the resolution process. It is crucial to respond promptly to recall notifications and schedule an appointment with your dealership.
Taking Action if You Suspect Your Vehicle is Affected:
If you believe your Jeep Wrangler PHEV falls within the suspect population or are experiencing any symptoms associated with this issue, it is essential to take the appropriate steps. Firstly, check if you have received a recall notification from Jeep. The notice will provide instructions on how to proceed and schedule an appointment with an authorized dealership. If you have not received a notification but suspect your vehicle may be affected, you can directly contact your local dealership to inquire about the recall and share your concerns.
The discovery of an unsecured fuse issue affecting certain 2022-2023 Jeep Wrangler Plug-In Hybrid Electric vehicles is a matter of utmost importance. If you suspect that your vehicle is part of the affected population or are experiencing any relevant symptoms, it is crucial to act swiftly by following the instructions provided in the recall notification or reaching out to your local dealership.
