Purchased vehicle in question on 9/11/25 as a lease through the local Jeep dealership near my residence. Sometime around 4/26 to 5/26 my vehicle started to display odd operational patterns which were brought to my local dealerships attention. The first event where I was able to record any type of documentation was around 5/25/26. While driving, the vehicle would suddenly go into "limp mode" and rapidly decrease speed. Several check engine lights would appear to include: Service Electronic Throttle Control, Service Electronic Stability Control, Traction Control and the standard CEL. When this does happen, the vehicle will decrease speed suddenly without warning and becomes difficult to operate until it is pulled over and parked. Vehicle has been to my local dealership several times (4) and out of service for over 70 days with the latest stay 30+ days. According to documentation from the dealership, the listed error/issue has been recreated on their end at least one time but no data was captured with that fail. My local Jeep dealership Service Manager (CF) replied to an email of mine (7/16/26 at 1703) with the following statement: Verified customer concern of check engine light on connect to wytec and found p2173 stored in powertrain control module. Also found c121c stored in ABS module. Believe ABS code is related to PCM code, cleared codes test drove multiple times. Finally able to get customer concern to duplicate but no data was captured on this failure. We are continuing to drive the vehicle while monitoring data to catch freeze frame data while concern occurs but have not been able to do so far at this time. The condition, when it occurs presents a serious safety concern for the driver and other drivers as it will cause a sever throttle limitation and can cause the vehicle to slow down rapidly. As of 8/9/26, no fix confirmed for my vehicle and the dealership and manufacture are pushing to return my vehicle with confirmed fix. Jeep case number 97378351

The 12-volt auxiliary battery and related electrical system in my 2025 Jeep Wrangler 4XE plug-in hybrid (leased new 8/25/2025) repeatedly fail. The battery completely discharges after the vehicle sits plugged into a standard home charger, undisturbed, for several consecutive days, leaving the vehicle completely inoperable. The vehicle is available for inspection upon request and is currently at a dealership. Failures to date (5): 11/05/2025: found dead after charging; required jump start. No warning lamps or messages precede the discharge events; the vehicle is simply dead when approached. 01/26/2026: dead after charging; would not jump start; towed. Dealer replaced the 12V battery and performed recall 68C software. 04/27/2026: check engine light illuminated while driving and the vehicle became stuck in electric mode; it would not switch to hybrid, gas, or E-save despite attempts, and a restart did not resolve it; towed. Dealer could not reproduce the fault. 05/17/2026: dead after charging; towed. 12V battery replaced a second time (same part number) and media hub replaced; vehicle was dead again at dealer pickup. 06/13/2026: dead after charging (plugged in undisturbed 6/9 to 6/13); towed. Tow operator noted the rear tires dragged during loading. Dealer/manufacturer confirmation: dealers have observed and documented the dead-battery condition multiple times, including a vehicle dead at pickup, but no dealer has reproduced the underlying failure or confirmed a root cause across five repair visits and approximately 56 cumulative days out of service as of 7/6/2026. The manufacturer's customer care team is engaged; it suspects a parasitic electrical draw, and the dealer is awaiting specialized test equipment. No police or insurance inspection. Safety risk: inability to leave electric mode while driving with the check engine light active; repeated complete electrical failures stranding occupants; an undiagnosed electrical draw in a plug-in hybrid that charges overnigh

The referenced vehicle "jerks/jolts" while driving. It was doing this when test driven on 7/31/25 and I was told by the salesman that this was normal even though he did not ask any questions about the jerking. On 8/1/25 I picked the vehicle up (leased). Because it had a cracked windshield, I again asked about the jerking and if it had any issues at all, and, again, I was told it was fine and nothing was wrong with it. The Jeep dealer serviced the vehicle x5 between 8/5-9/26/25 and was last in their service department from 9/3-9/26/25. The engine light has never been on and during the different service visits, an alignment was done, the valve cover gasket, oxygen sensor and valve body were replaced. No car accidents have occurred, however, because the "jerking/jolting" continued after the valve body was replaced, a lemon law case was requested and has been accepted.

The vehicle suddenly has a check engine light appear on the dash with a display message “performance limited, service fuel system”. This issue effectively caused the vehicle to enter a “limp mode” while driving it and limited its speed while driving. This reduced the speed of the car while driving at highway speed. The dealer has stated the issue is a high pressure fuel pump issue and a control module issue.

I was driving the Jeep on Route 35 in NJ when all of a sudden, the car lost power, jerked forward thrusting be towards the windshield. The "D" on the gear shift started blinking and the check engine light went on. The dashboard message indicated something along the lines that I had to put the car in parking "P". The car behind me beeped and almost rear ended me as it's a fast road and my car slowed dramatically and unexpectedly. Ultimately, I was able to glide into a parking lot on the side street and called the tow truck. The dealership said that a faulty OTA was sent out which caused the issue and that it has happened to many people. There were no symptoms or warning lights prior to the event. The dealership updated the vehicle and said it was safe to drive but I am not convinced based on the experience of others, which I have read in forums, who have had the same thing happen multiple times even after having the dealership update installed. Apparently, this OTA issue was widespread.

After jeep released an OTA update on Friday, I started my vehicle on Saturday and started to drive and in about 2-3 minutes all lights on dash started flashing and lost all power to vehicle and was luck enough to coast to the side of the road. The vehicle message said place car in park. Had to turn vehicle off then could shift into park. Then restarted now CEL is on but vehicle started and again 2 min later same problem no power had to coast to side of road, shut vehicle down and restart. This happen a several times one time I also lost power steering. I was just lucky enough to be on side roads and not the highway. The vehicle totally loses all propulsion and you have zero power to the vehicle and also lost power steering

After receiving a notification about a "uconnect update" on my infotainment and next start of my vehicle I experienced 3 loss of acceleration events within relatively short time intervals. When the event occurs, the dash flashes "P" and states the vehicle needs to be shifted into park, and restarted. First incident, I felt a hard thud when I shifted to drive. Upon the second incident (roughly 200 feet/10 seconds from the first incident), the check engine light came on, and the same message appeared. Forcing me to shift to park, and then restart the vehicle. The issue occurred for the 3rd time roughly 400 feet from where the second incident occurred. I have a tow scheduled to bring it to the dealership tomorrow.

Had an issue with a service charging system, and service hybrid system on my 2025 jeep wrangler 4xe that I’ve had for 7 mos. Under 10k miles. When checked, I was told it was a connector for the ac compressor, had a bent pin. On back order. 2 weeks + later, called to bring it in. The repair was a 16 hr repair, which I wasn’t notified of, service agent said tech completed it in 9 as I waited a total of 12 hours at the dealership. Was not told the eac and hv cable needed to be replaced. A few days later, check engine light came on. Phoned dealer, told to bring it in. Did so and service agent mentioned code about evap. Then, told me it required an update. Drove for 2 hours, check engine light came back on. Took jeep back and got a loaner. Told it was a purge valve solenoid that had to be ordered. Issue with the evap that they didn’t address the first time. The dealer phoned days later to say it was fixed, and when I arrived, I didn’t even make it out of the service lane before the check engine light came on again.
