2022 Jeep Wrangler: check engine light

Filed Oct 13, 2026 · Electrical, Engine · NJ

The check engine light was on and it said to service the battery charging components. When driving in hybrid mode it doesn’t switch to use the battery. When I was trying to pull off after stopping, the jeep hesitated and would not move and then all of a sudden jerked and took off almost making me crash and people crash into me.

I’ve had an ongoing issue with my car since earlier this year, 2026, and the code says “electric coolant heater” and i have a solid check engine light. they replaced the coolant heater a few months ago and now it’s doing the same thing again. There’s also another recall for the power steering and i’ve recently started to notice that when i start my car (which i normally will sit there for a few minutes before i drive to let everything “wake up”) there is a delay in the steering ability. my steering wheel will remain stiff unless i jerk the wheel to “wake it up” in a sense. this just started happening this week. the dealership that i got this thing at is being no help whatsoever and i’m getting tired of this!!! they don’t have a loaner car available to me so they’ve been telling me to wait to make a service appointment until they have a car available but i cannot wait on this issue any longer. matter of fact, this is absolutely ridiculous considering how much i pay for this thing every month and how lack of help the dealership has been!!!! I need a solution for this now

On October 8, 2026, at about 7:20 AM, my 2022 Jeep Wrangler (VIN [VIN]) lost gear selection while I was driving on highway 20 at highway speed. The check engine light came on, followed by a "Service Electronic Stability Control" warning, and then the transmission displayed "Shift to P then Desired Gear." Mileage was 23,816 to 23,819. This happened the day after I picked the vehicle up from a warranty repair for the same problem. It is the fifth repair attempt since I bought the vehicle on April 1, 2026: April 8 (valve body replaced), June 22 (TCM voltage codes P1DB9, P1614, U0402), August 25 (stability control warning), and October 6 (control module going offline intermittently, cause not found). The defect remains unresolved and creates a serious risk of a crash.

While driving my Jeep 4xe, the vehicle suddenly loses motive power without warning. The vehicle emits a chime, the "D" gear indicator flashes on the shifter and instrument cluster, the check engine light illuminates, and a message displays instructing me to shift the vehicle into Park. At that point, the vehicle will no longer accelerate, forcing me to coast and maneuver across traffic lanes to reach a safe location. This failure has occurred multiple times, including at highway speeds, creating an immediate safety hazard and increasing the risk of a crash. During several incidents, I narrowly avoided being struck by surrounding vehicles due to the sudden and unexpected loss of propulsion. The vehicle is currently at the dealership, and the dealership has confirmed the condition. A sudden loss of motive power while driving is a serious safety defect that requires immediate corrective action.

2022 Wrangler 4xe plug-in hybrid. The hybrid high-voltage system failed the first time it was used, in April 2026 at about 35,000 miles. I had not charged or used hybrid mode before that because of the manufacturer's high-voltage battery fire-risk recall guidance (recalls 23V‑787, 24V‑720, 25V‑741) not to charge and to park away from structures. The check engine light came on at first use and has not stayed off except when cleared by the dealer. The vehicle was taken to an authorized Jeep dealer for the same hybrid high-voltage system concern on 4/19/2026, 6/17/2026 and 7/5/2026 without a fix. On 8/4/2026 the vehicle would not start at all and had to be towed. It stayed at the dealer 29 days (8/6 to 9/4/2026). The dealer replaced the main battery and found DTC P0E15-00 (electric coolant heater performance) with the high-voltage coolant heater in a 'locked permanent' unrecoverable state, and replaced the HV heater. The three earlier visits never identified this high-voltage thermal-management failure. Safety risk: a sudden no-start / loss of propulsion, and a failed cooling component in the high-voltage system of a vehicle population already under repeated battery thermal-runaway / fire recalls, where the manufacturer has acknowledged fires in vehicles that had received earlier remedies. The failures were confirmed and documented by the dealer on repair orders. The manufacturer (Stellantis) has been notified in writing and has declined to repurchase the vehicle. Repair orders are available on request.

while vehicle is driving multiple dash alarms will start cycling through including stop/start, service electronic stability control, speed control messaging unavailable, service airbag system, service 4WD, engine light and ABS light, anti skid lights all come on, the speedometer goes to zero, and the power steering goes out. Driving highway speeds and suddenly having no power steering is a safety issue as well as being unsure if airbags etc are even functioning any longer. The problem has happened multiple times. The vehicle was inspected by a Jeep dealership as well as another shop in town and the codes were reproduced. They were unable to fix the issue and despite testing a "star connector" and finding it in good condition and unable to reproduce the issues were advised to replace that part anyway and see if they could reproduce the problem again at my expense. During this time the recall for 2022 Jeep Wranglers with the federal safety agency campaign number 26V363 came out and i requested to wait for further repair work to be done until the recall was repaired as it also relates to the power steering. I saw a fix had been published and return to the dealership to have the recall repair performed and was told that upon further inspection of the recalled part, mine passed the test, which was apparently a wiggle the wire and inspect the harness for ware only and my vehicle is no longer listed on the recall. I feel these things may still be related and I am extremely frustrated that I have a 4 year old vehicle that I am making payments on and paying insurance on that has been parked (not in my garage as it was a fire risk in the recall) and I don't feel its safe to drive and don't feel that Jeep or the local dealership are being honorable with their product.

On 7/25/2026, the vehicle set DTC P1128 (Closed Loop Fueling Not Achieved, Bank 1) with a steady check engine light and no drivability symptoms. I cleared the code with an OBD2 scanner. My wife had driven the vehicle to a local store and back earlier with no issues. Shortly afterward, with the vehicle loaded for a trip, she applied the brakes at the end of our driveway and the vehicle did not come to a complete stop. She described the pedal response as delayed. She proceeded onto our residential street at low speed and applied the brakes again. The brakes did not function properly. The pedal traveled to the floor with minimal braking effect and the vehicle came to a rolling stop rather than a controlled stop. She pulled to the side of the street and cycled the ignition off and on. She then drove approximately 10 to 20 feet and applied the brakes again with the same result: pedal to the floor, rolling stop only. Steering effort was normal throughout. We judged the vehicle unsafe to drive and cancelled the trip. It has not been driven since. Within 10 hours of the braking failure, the vehicle experienced a complete electrical failure. The key fob would not unlock the doors and I had to use the physical key. With the brake pedal depressed and the start button pressed, the instrument cluster illuminated for less than one second and then shut off, repeating. The vehicle would not start and remains disabled. No crash, no fire, no injury. The vehicle has open safety recall 21D (the federal safety agency 26V‑363) listed as incomplete. All other recalls were completed at dealer service in May 2026. Current mileage is ~62,000.

Unsure of the part or system that failed, however the auxiliary battery and power distribution system part was replaced previously and did not correct the problem. My safety was at risk when the speed and steering were affected. An independent service center worked on it and reproduced it. The car electronic system went through every warning light system while driving. "Stop/start not ready", "engine light", "airbag light", "service electronic stability control", SERV 4WD, ABS, BRAKE, "service airbag system", tire pressure monitoring, seatbelt light, "speed control messaging unavailable service required", and gas light all came on while driving. Speed was reduced and steering wheel locked up and released several times during the event.

The vehicle is a Jeep Wrangler 4xe with approximately 43,000 miles experiencing a recurring electrical system malfunction involving the Body Control Module (BCM) and LIN communication network. The vehicle is currently at the dealership and is available for inspection upon request. The failure involves multiple electrical circuits and communication loss between modules, confirmed by dealership diagnostic codes including BCM B1642-15, B1646-15, B16D7-15, B16DF-15, and U1123-00 (lost communication with LIN ECU). This condition presents a safety risk due to intermittent stalling/shutdown while driving, electrical system instability, and failure of critical systems including exterior lighting and HVAC. These issues create unpredictable vehicle operation and reduced safety for occupants and others on the road. The problem has been reproduced and confirmed by the dealership over at least four separate service visits, for which documentation is available. Despite repeated repair attempts, the condition has not been resolved and the same faults continue to return. The vehicle has been inspected multiple times by the dealership. The manufacturer, Stellantis, has been contacted but has declined further escalation or engineering review, citing warranty expiration. Warning indicators, including the check engine light, have repeatedly appeared prior to and immediately after service visits. Additional symptoms include intermittent heater failure while driving, system-wide electrical malfunctions, and abnormal noises. This is an ongoing, unresolved electrical system failure involving repeated unsuccessful repair attempts and presents a continuing safety concern.

We took the car in for the death shake and were informed there was a recall on the Jeep (25V741000). The dealership performed the maintenance work. The 12V battery was also inspected and listed as good. Since the repair, the 12V battery has shorted multiple times and finally ceased running yesterday. It has been two weeks since the dealership recall repair. While the recall specifically impacted the HV battery, the 12V is interconnected and the liklihood of that battery being impacted is high. The safety impact is the car temporarily not being able to gain power after stopping at red lights and the battery draining when stopped or turned off. The check engine light appears every time.
