2023 Jeep Wrangler engine problems

“On two separate occasions, the vehicle shut off while driving. Error messages indicated "electrical failure" and to "service charging system". In the second instance the check engine light came on. Both times I was able to get safely to the shoulder. The car was restarted by powering the vehicle off and then on again. October 2025- in Massachusetts on I290 heading back to CT from Maine February 2026- in CT on [XXX] The vehicle has been in and out of repair for several months at a time without repair or replacing parts. Software flashes clear the codes but have not fixed the ongoing issues. The manufacturer is aware and multiple cases have been opened with them without resolution.”

“Aug 6 2026 turtle limp mode came on. Lost power. Sept 5,6 turtle mode came on. Slowed to a crawl with several cars behind me. Oct 3 turtle limp mode came on. Lost power thru intersection. Thankfully no oncoming traffic. Oct 4 turtle limp mode came on. Had to pull over and restart vehicle in traffic”

“while driving my 2023 Jeep Wrangler Willys 4xe at approximately 40 mph in electric mode with approximately 26% battery charge remaining, the vehicle suddenly and unexpectedly lost propulsion. The green indicator on the instrument cluster that normally shows electric operation changed to yellow. Immediately afterward, the Jeep abruptly lost power and began rapidly decelerating. I was NOT applying the brakes. The dashboard displayed "Service Charging System" along with a red warning symbol resembling a charging cord. I was able to get the vehicle off the roadway and into a parking lot. The Jeep then came to a stop. The vehicle remained powered on and the dashboard remained illuminated, but pressing the accelerator produced no response. The Jeep would not move. I turned the vehicle completely off and waited several minutes. When I restarted it, the Jeep started and operated normally again. The Jeep spent approximately three months at an authorized Jeep dealership for multiple electrical/charging system problems and diagnostic trouble codes. During that time, the 12-volt battery was replaced and the Integrated Charging Dual Module (ICDM) was replaced. The Jeep…”

“On September 24, 2026, Recall 68C was completed on my Jeep Wrangler 4xe by an authorized Jeep dealership. Following completion of the recall, the first attempt to charge the vehicle resulted in an electrical fire at the charging location. During the charging event, the charger and electrical outlet melted, and the wiring connected to the outlet began to burn. The fire appears to have originated at the charging equipment and outlet. No visible damage occurred to the vehicle itself; however, the charger, outlet, and wiring sustained significant damage. Post-Recall Vehicle Performance Concerns: Since completion of Recall 68C, the vehicle has not operated correctly in Electric Mode. The following conditions were not present prior to the recall service: The internal combustion engine (ICE) repeatedly cycles on and off while the vehicle is displaying "Electric" mode on the instrument panel. Acceleration and overall vehicle performance are significantly reduced. The vehicle experiences severe throttle lag and delayed accelerator response. In some instances, there is little or no throttle response, followed by sudden engine engagement at engine speeds exceeding 3,000…”

“Subject: Performance Degradation and Drive Mode Faults Following Recall 68C Update – 2023 Jeep Wrangler 4xeTo Whom It May Concern,I am writing to formally report a significant degradation in vehicle performance and powertrain management following the completion of the Recall 68C software update on my 2023 Jeep Wrangler 4xe.Prior to the update, the vehicle operated efficiently and provided excellent torque and acceleration. I purchased this plug-in hybrid vehicle specifically to utilize electric-only (EV) mode for my daily 30-mile highway commute between [XXX] and [XXX].However, since the Recall 68C service was completed, the vehicle exhibits the following issues:Involuntary Engine Switching: Even when the vehicle is actively set to "Electric" mode, the hybrid powertrain constantly forces transitions between battery power and the internal combustion engine. This behavior occurs under normal driving conditions in ambient outdoor temperatures of approximately 80°F.Loss of Electric Powertrain Performance: The available power and torque in electric-only mode are noticeably diminished compared to the pre-recall performance levels.Compromised Vehicle Utility &…”

“After a recent recall (68C) the vehicle performance has greatly deteriorated. The ELEC mode propulsion has been limited, the internal combustion engine (ICE) engages much sooner than previous. Instead of a 'warm-up' cycle for the ICE, it feels as though there is actual clutch engagement, but with limited power. I feel this could have the potential to accelerate engine wear with a 'cold' engine with rapid engagement, as well as increased fuel/oil dilution (inherent with direct injection turbo engines). In turn, causing the vehicle to experience Fuel Oil Refresh Mode (FORM) more frequently, due to short, repetitive engine cycles. Additionally, the regenerative braking has been cut in half, leading to a decrease in electric charger egeneration to the HV battery, as well as decreased range and power. It is most obvious in stop and go traffic, when attempting to pull out in traffic, as well as when attempting to merge onto a highway or interstate. I feel, without intervention, the current vehicle performance will certainly lead to increased mechanical issues, a potential for frequent service department visits, as well as an increased potential for probable…”
