Jeep has recalled plug-in hybrid versions of the Wrangler and Grand Cherokee for a software issue that could disable the defrosting and defogging functions, the NHTSA disclosed Monday.
The recall is limited to only plug-in hybrid (PHEV) versions of the 2021-2024 Jeep Wrangler and the 2022-2024 Jeep Grand Cherokee. The 199,143 PHEVs included in the recall may have been built with a hybrid control processor that was incorrectly programmed. The software can cause the defrosting and defogging functions in the climate control system to be inoperable, leading to decreased outward vision on cold days.
Wrangler 4xe models built after Aug. 24, 2023, and Grand Cherokee 4xe models built after Dec. 5, 2023, have the software fix installed and should have full defogging and defrosting capability. For owners of models built before then, you’ll have to take your Jeep PHEV into a dealer for a software update to the control processor in question.
There have been 11 recalls for the 2021 Jeep Wrangler, but the noteworthy one specific to the 2021-2023 Jeep Wrangler PHEV is for an increased risk of the battery pack failing and causing a fire while parked or in motion. Issued Nov. 22, 2023, the Wrangler PHEV fire risk recall has been deemed “Urgent” by the NHTSA. Jeep advised owners to park the vehicles outside away from structures and to not charge them until the recall repair has been completed.
The defroster bug is the first recall for the Jeep Grand Cherokee 4xe.
For owners who have already paid to have the repair completed, Jeep will offer reimbursement. Owners will be notified by mail of the software fix by April 5. For more info, contact Jeep customer service at 1-800-853-1403 or visit Jeep’s recall website here.
