2023 Jeep Wrangler power train problems

“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…”

“My vehicles check engine light came on in the morning when starting the vehicle. It was a solid check engine light not flashing. I proceede to drive the vehicle and while pressing the accelerator the vehicle does not move. the engine done not connect immediatly, this is a hybrid vehicle so it attempts to use both the electrical and gas motors. The engin begins to rev very high and then after somewhere between 5-10 secounds of no power the vechicle jumps forward with the gas engine connecting. I attempt to put the vehicle into gas only mode, but this also does not work as this setting is turned off along with the electrical only mode. Other interior electronics are not working either. When attempting to drive to my local auto parts store to find out the codes for the check engine the vehicle shut off the gas engine preventing the vehicle from accelerating. Then seemingly randomly the engine will kick on and lurch the vehicle forward and then stop and turn off the gas engine again. The safty of myself and other are at risk because of the uncontrolable acceleration or loss of power randomly while driving. The problem has now been reproducable for multiple days. I…”

“After the 68c recall the power of the electric drive is limited. Frequent power loss occurs on highway driving during acceleration (merging onto highway or passing other cars). Despite the battery being charged up to 50% there is only 25% power available. The car is a plug in hybrid vehicle. The internal combustion engine starts in these cases with several seconds delay. During that time the car does not accelerate sufficiently to safely merge onto a highway or pass other cars. The power loss happens without warning during critical drive situations like merging onto a highway or passing other cars. The driver expects a continuous level of power by the car, not a sudden power loss. This is reported by countless other drivers on all social media platforms as a consequence of the 68C recall that affects 350 000 Jeep Wrangler 4xe and Grand Cherokee 4xe. Jeep does not respond to customer complaints or requests for clarification.”

“I own a 2023 Jeep Wrangler 4-Door Sahara 4xe (VIN [XXX], plug-in hybrid). Since new, this vehicle has had repeated electrical and high-voltage (HV) hybrid battery system failures. About eight months after purchase, at approximately 6,590 miles, the vehicle lost power and would not restart in a parking lot ("Service Charging System" warning) and had to be towed to the dealer (Repair Order #[XXX], 10/18/2023–10/20/2023); a 12V battery failure was diagnosed. On February 9–10, 2026, the dealer performed Recall Campaign 68C (JL/WL PHEV HV Battery) on this vehicle — a software/module update to the BPCM, HCP, AHCP, PCM, TCM, and IDCM, plus an HV battery diagnostic analysis (Repair Order #[XXX]). On [XXX], at approximately 22,692 miles, the check engine light illuminated and the dealer diagnosed a hybrid (HV) battery failure. The manufacturer (Stellantis/FCA US LLC) subsequently opened a warranty case (#[XXX]) and a lemon-law repurchase case (#[XXX]), confirming the vehicle could not be repaired and offering repurchase or $15,000 cash compensation. As of this filing, the vehicle remains at the dealership, out of service, well past the dealer's own promised repair…”

“While driving, my 2023 Jeep Wrangler 4xe suddenly loses drive power without warning. The car is a plug in hybrid vehicle. The vehicle routinely displays 'Electric Temporarily Unavailable'. When it happens, I press the accelerator and the vehicle does not respond; there is a delay of several seconds with little or no power before the gas engine engages. This is a serious safety hazard — the loss of power is sudden and unpredictable, and the delay leaves me unable to accelerate when merging or pulling into traffic. The condition is reproducible and began after the 68C recall software update. The driver expects a continuous level of power by the car, not a sudden power loss. This is reported by countless other drivers on all social media platforms as a consequence of the 68C recall that affects 350,000 Jeep Wrangler 4xe and Grand Cherokee 4xe. I have taken the vehicle to the dealer multiple times; each visit results in 'no codes found' and 'operating as designed,' and it has not been repaired. Jeep does not respond to customer complaints or requests for clarification.”

“Failed Component: Powertrain (PCM/TCM/HCP software calibration) & Electrical/Steering (Fire Recalls). Safety Risk & Description: Following recent mandatory manufacturer software updates, this vehicle has developed a severe, dangerous drivetrain defect. Under light acceleration from a complete stop, the vehicle exhibits an extreme throttle lag and hard delay before violently surging forward, creating a high risk of intersection collisions. Furthermore, at sustained highway speeds (52–63 MPH), the vehicle abruptly drops out of Electric Mode, causing the gas engine to violently spike to 5,000 RPMs before dropping back. This erratic cycling causes the vehicle to lurch, jerk, and pull, actively disrupting lane control. Compounding this, due to consecutive, unresolved fire safety recalls—including Recall 68C (Battery Fires) and the June 2026 Power Steering Pump wiring fire recall—the vehicle cannot be safely parked inside my garage or near structures while turned off. It represents a total loss of normal use and a severe safety liability. Dealer Confirmation & History: The driving defect was formally duplicated and confirmed by a certified technician on 06/09/2026 at…”
