Chrysler (FCA) will be contacting the owners of certain 2021-2024 Jeep Wrangler and 2022-2024 Jeep Grand Cherokee over a failure to comply with Federal Motor Vehicle Safety Standards (FMVSS) related to windshield defrosting and defogging systems. Owners of affected vehicles are urged to take immediate action to rectify this potentially hazardous issue.
In June 2023, FCA Technical Safety and Regulatory Compliance (TSRC) organization received reports indicating a potential malfunction in the windshield defrost system of certain 2021-2024 Jeep Wrangler Plug In Hybrid Electric Vehicles (PHEVs) and 2022-2024 Jeep Grand Cherokee PHEVs. This issue raised concerns about the vehicles’ compliance with FMVSS.
An investigation conducted by FCA determined that a subset of these vehicles may have been built with incorrectly programmed hybrid control processor (HCP) software. This flaw could result in the disabling of the windshield defrost system under specific conditions. The affected period for the Jeep Wrangler spans from September 2, 2020, to August 24, 2023, while for the Jeep Grand Cherokee, it extends from July 23, 2021, to December 5, 2023.
A disabled windshield defrost system poses a significant safety risk, as it can impair outward visibility during critical driving conditions, potentially leading to accidents. In response to this safety concern, FCA has initiated a voluntary safety recall of the affected vehicles.
To address the issue, authorized dealerships will update the HCP software to rectify the programming error. This corrective action aims to restore the proper functioning of the windshield defrosting and defogging systems, ensuring optimal visibility and driving safety for affected vehicle owners and occupants. This recall, identified as recall number 04B by Chrysler, carries the NHTSA campaign number 24V-111.
