2023 Jeep Wrangler: hesitation when accelerating

Filed Sep 19, 2026 · Fuel system · MO

Following completion of the 68C recall/software update around January 31, I noticed a significant change in the performance and drivability of my Jeep Wrangler 4xe. The most noticeable difference was a reduction in acceleration and overall power. The Jeep no longer had the quick, torquey response it previously had, which was one of the primary characteristics that attracted me to the 4xe. At times, pressing the accelerator resulted in noticeable hesitation and very weak acceleration. On one occasion, I pulled into traffic expecting the Jeep to accelerate normally, but it initially did not respond as expected, requiring substantially more throttle to get the vehicle moving. This created a legitimate drivability and safety concern. My impression was that the vehicle's hybrid/electric output had been significantly restricted following the recall update. Based on discussions occurring among other 4xe owners, similar behavior was being described as the vehicle being "nerfed," with reduced electrical output and battery utilization intended to protect the high-voltage battery. Regardless of the cause, the reduction in performance was clearly noticeable compared with how the Jeep drove before the update. In the period leading up to the eventual failure, I also noticed that the Jeep's acceleration felt increasingly abnormal. In retrospect, the change was noticeable enough that I suspected something might be developing before the vehicle ultimately failed. The Jeep later developed a high-voltage battery fault associated with battery-pack voltage variation/cell imbalance. The vehicle displayed warning messages, including "Service Charging System," along with a check-engine light. It also experienced rough idling and eventually became unreliable to start or move. The failure progressed to the point where the Jeep broke down while I was leaving home. After shutting the vehicle off, it would not reliably restart. At different points it briefly powered on, including while bei

Sometimes pulling out my wrangler hesitates to accelerate. I've had couple of scary situations megeing onto the highway and pulling out at a intersection. Sometimes going up hill it seems to lose power. The Jeep used to never have a problem in any of these situations. Something has seemed to change. Help!

My 2023 Jeep Wrangler 4xe High Altitude received FCA Recall 68C. Since the recall was completed, the vehicle has experienced repeated and unpredictable reductions in available propulsion during normal driving. The problem is most noticeable when accelerating to merge onto highways, enter traffic, or pass slower vehicles. During these situations, I depress the accelerator expecting normal acceleration, but the vehicle frequently provides significantly reduced power. There is a noticeable delay before the gasoline engine produces sufficient propulsion, leaving the vehicle unable to accelerate as expected for several seconds. Based on my experience, the condition is significantly worse during hot weather. As outside temperatures increase, the hesitation and reduction in available propulsion appear to occur more frequently and are more pronounced. This has caused me to lose confidence in the vehicle's ability to accelerate when needed. This condition creates a serious safety hazard because surrounding traffic continues at highway speeds while my vehicle is unable to accelerate as commanded. In [XXX], this hazard is particularly acute because many interstate and highway entrance ramps are relatively short, requiring drivers to accelerate quickly to merge safely into traffic traveling at highway speeds. When the vehicle unexpectedly limits propulsion or delays engaging the gasoline engine, there may not be sufficient distance to reach the speed necessary to merge safely, increasing the risk of a collision. The same issue also affects attempts to pass slower vehicles on two-lane highways, where timely acceleration is essential for safe operation. The vehicle does not display diagnostic trouble codes or warning messages when this occurs. Because no diagnostic codes are stored, I have not taken the vehicle to the dealer, as other owners have reported that dealerships are unable to identify or repair the condition in the absence of fault codes. The lack of diagnostic codes INFORMATION REDACTED PURSUANT TO THE FREEDOM OF IN

Recurring incident after completion of Jeep recall software update 68C intended to address fire hazard associated with the vehicle's hybrid battery. Since that update, when driving in standard Electric mode, the vehicle experiences a sudden loss of power, hesitation, and a physical 'bogging down'. Following this, the vehicle abruptly surges into combustion engine mode, causing a sudden and unpredictable acceleration lurch just after the vehicle has hesitated to accelerate. It poses a hazard for rear-end collision, attempting to pick up speed (e.g., to pass or move from a vulnerable position) and overall maneuvering and operation of the vehicle.

Our Jeep 4Xe underwent the recall for the hybrid battery. The battery was replaced in May 2026, since then the vehicle hesitates to accelerate at speed causing a safety concern. This vehicle has been recalled so many times we have no confidence in the vehicle.

I am submitting this complaint regarding a safety concern with my Jeep following the completion of Recall 68C. Since the recall service was performed, the vehicle has experienced significant issues when operating in hybrid mode. While driving in hybrid mode, the vehicle repeatedly switches back and forth between hybrid and electric operation. When the vehicle enters electric mode, the RPMs will suddenly spike and the vehicle will call for the gasoline engine. When the accelerator pedal is pressed, the vehicle is unable to maintain electric power and immediately switches into gasoline mode. This behavior results in constant drivetrain shifting and erratic engine speed changes. The RPMs frequently jump from 0 RPM (electric operation) to approximately 3,000 RPM when the gasoline engine abruptly engages. The repeated transitions between electric and gasoline power create noticeable hesitation, jerking, and inconsistent acceleration. This issue began only after the Recall 68C service was completed and was not present beforehand. The repeated switching between propulsion modes appears abnormal and may pose a safety concern, particularly during acceleration or when merging into traffic where predictable vehicle response is critical. I am submitting this report so that this issue can be documented and investigated to determine whether the recall repair may have introduced or failed to correct a problem within the hybrid drivetrain system. 2023 Jeep Wrangler 4XE Unlimited
