2021 Jeep Wrangler

My vehicle is currently in the shop getting the High voltage battery replaced for the second time due to a code showing battery voltage variation as well as getting the latest 21D recall completed. The Jeep currently has about 90,000 miles and has received all other recalls. The jeep no longer functions or performs like it did when I took ownership in February of 2022. It routinely loses power when trying to accelerate onto Highways or into traffic lanes or up hills. You can push the pedal down and there is a noticeable delay of several seconds before the vehicle starts to accelerate. The car no longer will stay in selected "Electric mode" and will instead kick the engine on at random times or take the vehicle out of "electric" and into "Hybrid". When at slow speeds (under 15MPH) in traffic the jeep lurches and slows, unable to maintain a constant speed. Also I have no way of proving that the overall power has been reduced through programming but the acceleration and advertised 375HP/470lb-ft does not seem to have the same feeling that it once did when first purchasing this vehicle. I believe there is a dangerous ongoing safety issue possibly with the programming, as well as the HV batteries. There were no warning lights coming on during the course of the last several months until I had a CEL for battery voltage variation and then it was taken to the dealership on the same day. There has been no communication with Jeep/Stellantis other than them issuing an unlimited mileage warranty on the HV battery. They seem to be replacing it with the same design, and therefore not addressing the issue only putting a band aid on the problem.

My 2021 jeep wrangler Sahara 4xe has had numerous EV battery issues. I have asked recalls to be fixed. It has had its battery replaced under a federal safety recall, still refuses to charge, and caused home charger to no longer to work. It has been in the shop since 8/11/26 and they are unable to get it to charge. This is a safety hazard. Issues with the EV battery/electrical system started back in 2021 after purchasing vehicle. Most recent issue with frying my home charging unit and not charging started in July of 2026.

Since recall 68C was completed in February, the performance of the vehicle in Electric mode has degraded significantly. Prior to 68C, the gas engine was nearly impossible to engage in electric mode which was a good thing and clearly intended for extreme circumstances where unusually rapid acceleration was required. Also prior to 68C the electric acceleration was dependable and predictable both around town and at highway speeds. I live atop a 1.5 mile hill and could travel bottom to top without the engine engaging. Since 68C, I have consistently observed multiple changes in performance in electric mode: 1) the engine will engage much sooner and more frequently upon acceleration in any conditions. Wherever it happens, this is an unpredictable behavior that puts instant load on a cold, unlubricated engine. 2) At and approaching highway speeds in electric mode, the vehicle will begin to lose acceleration, hesitate and the gas engine will engage - again putting load on a cold, unlubricated engine. This can happen after several miles or after just a few miles. When the engine engages, it does not engage smoothly - the engine will rev high then drop down, then rev high then disengage - all inconsistently and all unexpectedly. While this is happening, the vehicle's acceleration or ability to maintain speed is inconsistent and constant manipulation of the throttle is necessary to ensure I'm not losing too much speed relative to the traffic around me. I don't know what changes were made as part of the 68C recall remedy but it has dramatically changed how electric mode is managed, has significantly decreased vehicle performance in electric mode and puts my and my passengers' safety at risk when I'm driving. The problem has not been reproduced by a dealer and I've confirmed that the latest software is installed. The component has not been inspected. The issues described above only presented after the 68C recall work was performed and occur without warning.

Death wobble

Since the 68c recall my vehicle has not been performing as it should. It is in the shop for the 110th day since i had the recall installed.

Since the last 2 updates / recalls , my transmission has become very clunky. From a stop or in slow traffic, the transmission pops in gear and it is very hard. It seems to be getting worse as time goes by. The gears when shifting thru the gears is fine, no issues there

2021 Jeep Wrangler 4xe Sahara, VIN [XXX]. 1. The exact malfunctioning component is UNKNOWN; I suspect the hybrid propulsion system. The vehicle is available for inspection. After recall 68C was completed, accelerator response, electric-power availability, and combined gasoline/electric performance changed substantially. The Jeep hesitates when I press the accelerator, the gasoline engine starts at unexpected times, and full electric-mode operation becomes restricted. Combined acceleration is noticeably weaker than before the recall. My complaint concerns restricted propulsion power, not reduced driving range. Horsepower loss has not been independently measured. Whether battery overheating or thermal-protection controls cause these restrictions is UNKNOWN. 2. I regularly pull out into traffic expecting the acceleration the vehicle previously provided, but the Jeep hesitates or fails to gain speed quickly enough. The approaching driver behind me then has to slow down. This recurring delayed response and reduced acceleration make safe gaps harder to judge and create a risk of a rear-end collision. 3. No dealer or independent service center has reproduced or confirmed these post-recall problems. 4. Recall 68C was completed, but these subsequent drivability problems have not been inspected by the manufacturer, police, insurance representatives, or others. 5. I first noticed these symptoms on XXX, at 62,000 miles, after recall 68C. They became more pronounced during summer 2026 as warmer weather set in. No warning lamps or messages accompanied these problems. I suspect a connection to the recall work based on the timing, but the exact cause is UNKNOWN. I request that NHTSA investigate whether the 68C remedy causes or leaves unresolved restricted propulsion power and delayed accelerator response.

I had a 68c recall completed by Jeep and immediately after the recall, I noticed a reduction in power when accelerating, which causes me issues when trying to merge on the freeway and stay with the flow of traffic. This has been an ongoing daily issue. Also, the gas engine kicks on when it should not and loads immediately causing an erratic shifting of the gas engine, which causes the vehicle to lose power when it is needed the most. The recall was designed to supposedly protect the electric battery, but the software update that Jeep implemented has drastically changed the functionality and response timeframe at which the vehicle can respond when accelerating. I have tried to have Jeep address the issue, but they indicated the Jeep is operating as intended. It never operated like this until after this recall update and many other Jeep 4xe owners are reporting similar issues with propulsion and the gas engine loading erratically. Thank you for looking into this safety concern.
