Jeep Recalling Nearly 63,000 Wrangler 4xes Over Engine Shutdown Issues

Jeep has issued a recall of 62,909 Wrangler 4xe SUVs due to the possible unexpected loss of engine power. The root cause of the issue is not clear, but the problem can be fixed with an updated software calibration for the transmission control module and auxiliary hybrid control processor. NHTSA suggests that 100 percent of the vehicles recalled could have the issue; Jeep is aware of two accidents and one injury that could be related to the defect.

Jeep is recalling just under 63,000 Wrangler 4xe SUVs due to an issue that has the potential to unexpectedly shut off the engine while driving, which could lead to a crash. The defect affects some 2021–2023 4xe models and looks to be associated with the plug-in-hybrid powertrain. However, according to documents filed by Jeep with the National Highway Traffic Safety Administration (NHTSA), 100 percent of the 62,909 vehicles involved are defective.

Jeep is still investigating the root cause of the problem which appears to stem from somewhere in the transmission control module and the auxiliary hybrid control processor. A fix is said to be available with a software update to both systems.

According to paperwork filed on Nov. 3, 2022, Jeep is aware of two accidents and one injury that are potentially related to the 4xe’s defect. At that point in time, Jeep knew of 112 customer-assistance records, 196 warranty claims, and 65 field reports potentially linked to this issue over a two-year period between Dec. 17, 2020 and Oct. 26, 2022.

As of the most recent NHTSA filing, Jeep hasn’t announced a “Stop Drive” order. The company plans to begin notifying dealers and owners on Jan. 12, 2023. Before then, owners are able to check the NHTSA recalls site for more information about the recall, and to plug in their VIN to see if their vehicle is affected.
