2023 Jeep Wrangler engine problems

Filed Nov 3, 2026 · Electrical, Engine · CA

The Jeep was purchase used from a Jeep dealer in April 2026. At 42,821 miles it was still under the manufactures warranty. We have had multiple occurrences where the check engine light comes on, followed by other warning lights, and moments later the Jeep will stall in traffic. When it stalls, it is unable to be restarted or shifted to neutral to be pushed out of traffic. This has cause multiple seriously dangerous situations and collision close calls. Sometimes a jumpstart will allow the vehicle to be restarted. other times it must be towed. Note: The battery and electrical systems checks indicate no failures even though the battery/low voltage warning lights come on during the incidents. I have taken the vehicle to four different repair facilities including authorized Jeep dealer service centers. The first three times parts were replaced. The fourth time it was towed to Santa Monica Jeep. They verified the same error codes as reported previously then cleared the error codes. One they cleared the error codes, they were unable to get the check engine light to come back on during their short test drives. And none of the components were testing as bad. So I requested a Stellantis field technician inspect the vehicle. They were also unable to diagnose the problem even though it keeps recurring. Because they were unable to diagnose the problem, they refused to take any further action, even though the service manager told me that the vehicle is unsafe to drive. I informed my insurance company of the situation and they told me that they may not cover any claims unless the dealer provides a "Certified Mechanics Statement" or "proof of repairs showing that the vehicle is in good physical condition and safe to operate." The dealer refuses to provide this. So now I have a Jeep that is unsafe to drive, may no longer e covered by my insurance, and neither a Jeep dealer nor Stellantis themselves are willing to resolve a dangerous stalling problem.

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.

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 operated normally for approximately three months following those repairs before this incident occurred. This was an extremely serious safety event. The vehicle unexpectedly lost propulsion while actively traveling on a public roadway. If this had occurred at highway speeds, while merging, crossing traffic, or in heavy traffic, I may not have been able to safely get the vehicle off the roadway. I am particularly concerned because the malfunction disappeared after shutting the vehicle off and restarting it, making the failure intermittent and unpredictable. I am requesting that the federal safety agency investigate this sudden loss-of-propulsion incident and determine whether it is related to other reported loss-of-motive-power problems involving Jeep Wrangler 4xe vehicles.

From a stop sign vehicle would only accelerate to 4 mph and then completely lost forward propulsion, forcing a tow to the dealership.

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 RPM. Vehicle operation in Electric Mode is inconsistent and unpredictable. These performance issues began immediately following completion of Recall 68C and have persisted since the recall service was performed. Additional Information: I have become aware of reports from other Jeep 4xe owners who have described similar drivability and Electric Mode concerns after completion of Recall 68C. Given the charging-related fire event and the significant changes in vehicle operation that appeared immediately after the recall was performed, I am requesting that the federal safety agency investigate whether these conditions may be related to the Recall 68C remedy or associated software and system changes. Safety Concerns: Fire hazard during charging. Loss of expected vehicle performance. Delayed or unpredictable throttle response.

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 incidents/accidents during operation. I understand Stellantis has offered an extended warranty for the HV battery (unlimited years/miles, with limitations). However, Samsung SDI should be pressured to actually fix their HV battery, not replace it with a similar known faulty battery. This vehicle, in my honest opinion, can be made safe and reliable, but only with intervention and pressure from outside agencies with the power to force the manufacturer(s) to do so -- and my service department agrees. That is why I am elevating these issues, to hopefully enact change, and quite possibly, reduce the potential for catastrophic failures and/or an increased potential for accidents resulting in injury/death. Thank you for your concern with this matter.

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 & Increased Operating Costs: Because the gasoline engine frequently overrides the electric settings, the primary functional utility of the PHEV system is negated. This failure to maintain electric propulsion has dramatically increased my fuel consumption and operati the safety software update deployed to mitigate high-voltage battery cell risks has fundamentally compromised the vehicle's advertised performance, utility, and drivetrain integrity. I request that the federal safety agency investigate whether these post-recall performance changes constitute a systematic defect and urge Stellantis/Jeep to provide a permanent software or hardware correction. Thank you for your attention to this matter and for your oversight regarding consumer vehicle safety and compliance. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Post 68C recall, the vehicle performance in all electric mode is greatly diminished. At lower speeds, and electric motor exertion, the vehicle will rapidly and violently switch to combustion power going from 0-3500 rpm’s with no engine warming cycle. Additionally, at 50% battery charge and below, the vehicle can fail to accelerate at all, experiencing a near dead gas pedal, which can be seriously unsafe when attempting to merge or turn into traffic. Based on my experience, these symptoms are exacerbated by warm temperatures, which may be indicative of the manufacturer changing battery temperature thresholds to protect a still defective battery. This vehicle no longer performs as it was advertised and sold to perform following multiple recalls for the same issue. This needs to be resolved once and for all, as it has become a much less safe vehicle to drive as it will switch from ICE to electric unpredictably, causing either rapid, unexpected acceleration or a dead pedal from a stop. Please hold the manufacturer accountable
