2023 Jeep Wagoneer problems

Filed Nov 6, 2026 · Electrical, Engine · NH

The check engine light illuminated on my dashboard when I was driving with my family. On 4 separate occasions as I was coming to a stop, the vehicle unexpectedly shut off (driving at about 5 MPH). When it shut off, it shifted itself into Park and the parking brake was auto-applied. On each of the incidents, I was able to manually restart the vehicle by pushing the ignition button and shifting it back into Drive.

Issues began on 9/29/26 - The transmission was slipping and failed to shift numerous times when accelerating causing a loss of power. This happened several times at highway speeds when passing. Warning lights came on after this issue occured. This issues happend several times over the course of about a month. These issues put my safety at risk multiple times when I was suddenly not able to accelerate to pass or in some instances not able to accelerate to enter the interstate. This issue also occured at a low speed in stop and go (interstate) traffic. The vehicle would not shift out of 1st gear and I was forced to drive on the interstate at a dangerously low speed until I could exit the interstate. Warning lights came on due to this issue. The Jeep dealership assessed the vehicle and determined that the transmission needed replaced. The transmission was replaced at a certifed Jeep Dealership. The vehicle was tested, deemed repaired, and returned to me. The next day the same issue occured where the transmission would slip, grind, and then lose power. That same day the vehicle lost power completely while driving. The engine shut off while I was driving. When I pulled over began to slow the vehicle automatically and abruptly shifted itself into park. This again put my safety at risk by the loss of power while driving and unexpectedly shifting into park. The vehicle is currently at the same Jeep Dealership being assessed. I

Vehicle will suddenly shut off in traffic. Will NOT start back up for 1-2 minutes. Control panel near gear selector will flash on and off message reading Hold brake and start button. Screen all black. This has happened 3 times this month. Car shut off in car wash, once started it would not shift from Park into Neutral or Drive for 60 seconds. When accelerating on expressway, vehicle will shake then message flashes on dashboard "Put in proper gas and oil". Happens weekly. Dealership of course cannot find any issues or replicate codes....very convenient. Bought new-2023 Jeep Wagoneer Series 2 Hurricane twin-turbo engine.

The thermostat suddenly failed, causing extensive engine failure. The engine failure was the direct and unavoidable consequence of a known manufacturer defect explicitly covered under Customer Satisfaction Notification 26B and TSB 09-006-25 / RSU 25-047 which should have replaced my thermostat or been a recall.

About a week ago, I received a warning that my lane management assist required servicing. As of Tuesday (10/06), as I slowed to a. Stop sign, my car started beeping, put itself in park and turned off. It flashed a message that stated a restart was required. Then today, I was getting the same lane management warning and as I was stopped, my car did the same thing, threw me into park, put a bunch of different warning messages then said power steering requires service. I proceeded to drive home since I was about ten minutes away, shut my vehicle off for a few minutes and tried to restart it, the car would not restart. The vehicle had to then be towed to dealer for repair. Since purchasing the vehicle in 01/2024 I have had ongoing electrical issues and had to turn the vehicle in for service. But they have never found an underlying issue, they have just replaced batteries and cleared codes

I own a 2023 Jeep Wagoneer with approximately 33,000 miles. The vehicle has unexpectedly shifted/commanded PARK while moving on two separate occasions. The first incident occurred while I was driving approximately 5 mph in a parking lot. The vehicle unexpectedly went into PARK while it was moving. The second, more serious incident occurred while I was accelerating from a complete stop to make a left turn onto a main road. The vehicle unexpectedly shifted/commanded PARK while I was accelerating into traffic. I did not select PARK and could have been tboned. I reported both incidents to my Jeep dealership. The vehicle has been inspected, but the dealership has been unable to duplicate the issue and states there are no DTCs or other indications of a failure. Because they cannot reproduce the concern, they have declined to escalate it to a Chrysler/Stellantis representative. They are returning the vehicle to me despite the issue occurring twice. I am concerned this is an intermittent electronic, transmission-control, shifter, sensor, software, or communication-related safety defect that may not leave a diagnostic code after the event. An unexpected shift into PARK while moving could cause sudden loss of propulsion or control and presents a serious safety risk, particularly when occurring while accelerating into traffic. I am requesting that the federal safety agency document this complaint and investigate whether there are similar incidents involving 2023 Jeep Wagoneers unexpectedly shifting into PARK while moving.

When driving my vehicle suddenly shuts off the engine and puts the vehicle into park. This has happened multiple times now and everything shuts down, power steering, etc goes out and I’m afraid it will cause a serious accident.This seems very dangerous. Dealership tells me they don’t have any idea how to fix it

I recently had an oil change at the dealership I purchased the Wagoneer from. Three days after the oil change was completed, I was sitting at a stop light when the vehicle completely shut down, and the power steering went out. I started the vehicle back up and a power steering service notice popped up. That same day, the large central display screen kept flashing on and off, when it finally shut completely off. Six days later, I was driving home from work when I noticed the engine kept running up into the 6-7000 RPM's if I tried to drive over 40mph. I drove under 40mph the rest of the way home (about 10 minutes) and started noticing how loud the engine sounded and the temperature gauge was increasing. I was about 1 minute from home when my daughter and I could feel the heat coming from the engine inside the cab of the vehicle. It was so hot, I was concerned the vehicle was going to catch on fire. I parked it away from my home and called the dealership. They sent a tow truck and inspected it the next day. They stated the engine thermostat went out, and the auxiliary battery failed. There were never any warning lamps or messages displayed while this was happening. If I would not have been paying attention to the gauges and would have been further away from home, this vehicle could have overheated completely and potentially caught on fire putting my kids, myself, and others on the highway in danger. There was a Campaign Reference: 26B issued by Stellantis in April 2025 stating this exact issue and noting the repair to be performed, however, they only included specific Wagoneer's equipped with a 3.0L GMET6 engine. My engine is a 3.0L I6 Hurricane and was not included in the campaign, even though it is the exact same issue and this could have all been avoided.

Instrument panel dash frozen. instrument dash panel frozen at the screen where it says start/stop press brake to turn the vehicle on, we can’t see how fast we’re going when driving. This has occurred on multiple occasions. We’ve taken it to a Jeep dealership. Who reset the PCM but it does not resolve the issue.
