Jeep Wrangler 4xe – 2021-2023 – NHTSA RECALL INVESTIGATION

Jeep Wrangler 4xe owners report “loss of motive power”

JULY 2024 — AP.com — The U.S. government’s auto safety agency is investigating a potential “loss of motive power” in more than 94,000 Jeep Wrangler 4xe vehicles, after receiving complaints for cars outside the scope of an earlier recall involving an engine shutdown condition in the same SUV model.

The National Highway Traffic Safety Administration says it opened a recall query on Friday “to assess the severity of the alleged defect” as well as the effectiveness of the remedy provided in the previously announced recall.

Back in November 2022, the NHTSA announced a recall of nearly 63,000 model year 2021-2023 Jeep Wrangler 4xe vehicles equipped with a plug-in hybrid electric vehicle engine. At the time, NHTSA documents warned that these cars may experience engine shutdown that could result in sudden loss of motive power while driving.

A calibration software update was provided as a remedy to impacted owners, but more complaints still piled up since. In its recall query summary published this week, the NHTSA’s Office of Defects Investigation noted that it’s identified 68 owner reports alleging a loss of motor power for Jeep Wrangler 4xe vehicles of model years 2021 now through 2024.

According to the NHTSA, these failure complaints involve both vehicles that already received the remedy for the 2022 recall and those not initially included — although the current rate of reports is higher among the “out of scope” Wranglers than those that were later covered by the recall, the regulator noted.

Jeep recalls 63,000 Wrangler 4xe PHEVs due to engine shutdown problem from model years 2021-2023

The company also issued a stop-sale order to dealers

December 2022 – autoblog.com — Jeep has issued a recall that applies to nearly 63,000 units of the plug-in hybrid Wrangler 4xe built between the 2021 and 2023 model years. The engine in SUVs included in the campaign can unexpectedly turn off due to what the manufacturer calls “a loss of communication.”

Assigned campaign number 22V865000 by the National Highway Traffic Safety Administration (NHTSA), the recall includes 62,909 units of the Wrangler 4xe built between September 2, 2020, and August 17, 2022. Jeep notes that only plug-in hybrid models are affected by this problem; the non-hybrid Wrangler isn’t part of the recall. The company says these SUVs can experience “an engine shutdown condition caused by diagnostic reactions to faults caused by loss of communication.” Losing power while driving increases the risk of a crash.

Owners of affected cars will receive more details about the recall via mail starting on January 12, 2023. In the meantime, Jeep has issued a nationwide stop-sale order for the Wrangler 4xe……. MORE >>
