Engine And Engine Cooling Problems of Jeep Wagoneer - part 1

Vehicle: 2024 Jeep Wagoneer (base model) the vehicle has experienced ongoing and progressively worsening engine performance failures, specifically involving unstable rpm behavior and loss of power during idle and re-acceleration from idle. These defects have been present on multiple occasions and occur under normal operating conditions. While stopped at traffic signals or intersections, the vehicle frequently exhibits sudden and erratic rpm fluctuations, followed by a sharp drop in engine speed resulting in complete engine shutdown. These shutdown events have occurred both while the vehicle is in park and while actively positioned in traffic, creating a hazardous condition. In several instances, the engine stalled unexpectedly while the vehicle was stopped at a red light, requiring an immediate restart in an active traffic environment. In addition, when transitioning from an idle state to acceleration, the vehicle has demonstrated abrupt surging and jerking behavior, causing sudden forward movement. This creates a significant risk of unintended acceleration and near-collision events, particularly in congested traffic conditions or when stopped closely behind another vehicle. The vehicle was presented to an authorized Jeep dealership for inspection. The dealership advised that no diagnostic fault codes were present and no defect could be identified. However, during the dealer’s evaluation, the vehicle did stall while being allowed to roll into the service bay in an idle state, directly corroborating the reported condition. Despite this occurrence, no corrective repair was made, and the vehicle was returned without resolution. The frequency and severity of these symptoms have increased over time, resulting in a vehicle that is unreliable and unsafe to operate. The continued occurrence of engine shutdowns and erratic acceleration behavior presents a clear and ongoing safety risk to the driver, passengers, and surrounding motorists.

This vehicle engine overheated. Leading up to the engine overheating event, there was an instance where the vehicle was driven for a mile or two and the air conditioning seemed to not be cooling. The vehicle was turned off for a few hours and restarted and the air conditioning appeared to work. However, the next day, the engine overheated. All repairs associated with this event were completed under warranty at no cost to the customer however, this is the 2nd Wagoneer we own and the other one had similar issues.

It seems that when the outside temperature is very warm/hot, when turning the car on or when idling at a traffic light or driving at very low speeds, on occasion the car will abruptly and without warning, shift itself into park and the emergency brake activates. I took the vehicle in for repair on 10/23/25 and was told there was a "thermostat internal failure" and that the "thermostat assembly" was replaced. I was just recently traveling in florida ( reside in NY) and the exact same problems occurred with my vehicle which I can only assume was due to the warmer temperatures that my vehicle has not been exposed to since the last repair as I reside in new york. I feel it should be worth mentioning that when turning off the auto start/stop button, the problems occurred less frequently but still happened on occasion. I've also had 3 other times when the "check engine" light came on. I was told that the first 2 were related to software updates with the transmission. On the other occasion, a "valve body" was replaced. I'm unsure if any of these were related. I've also had to replace the auxiliary battery but I don't think that's related so I didn't upload that file. Although I'm taking the vehicle to be repaired today, I took it in on 04/14/26 because the check engine light came on while in florida when the car shifted itself into park and the emergency brake was activated. The check engine light almost never comes on when this happens which I was told makes it difficult to diagnose issues. I didn't know how long this info is stored so I took the vehicle in upon returning to NY and was given a summary report after they hooked up a scanner. I couldn't get an appointment until today.

I was driving about 10mph around a turn and the motor turned off and I had to park to start the motor again. When I came to a complete stop the car engaged it's parking break and suddenly jerked forward. This has happened several times in the last year and this time I was the driver of the vehicle. It's a extreme safety issue and my wife has had it happen to her at a busy intersection more than one time.

The vehicle flashed a critical low battery warning while in operation driving. After traveling approximately 2 miles further, the vehicle warning lights started flashing and the vehicle shifted into park and shut off. In the middle of the road the vehicle could not be shifted into neutral and was stuck in a dangerous place. The emergency flashers shut off after 15 minutes while waiting for a tow truck. This vehicle has had two battery replacements in the last two years.

This vehicle has had 2 incidents where the engine overheated. In both instances, the thermostat has been replaced under warranty. Due to this most recent overheating event, the repairs were over $1750 excluding the portion of repairs under warranty. There were no warnings before the engine overheated, and the vehicle was being driven on the freeway at appropriate speeds. This is not the first time this vehicle has overheated.

Our 2023 Jeep Wagoneer overheats (indicates excessive oil temperature and low oil pressure) repeatedly (~20 times since we've owned the vehicle) under normal freeway driving causing a safety issue by creating the need to rapidly slow and exit the roadway to prevent vehicle engine failure. The issue occurs during sustained freeway driving around 60-65 mph. The car feels like it is not properly shifting to the next gear and the rpm lingers around 3000rpm - 3500rpm. After a few minutes at this sustained rpm the engine temperature gauge slowly climbs until the overheating warning light comes on and it typically followed by a low oil pressure warning. We have taken the vehicle to a Jeep dealer twice. They have tried to replicate the issue and have not been able to. We suspect that they are not driving in long enough (30-40min) to be able to replicate the issue. They also say that they are not able to pull up any error codes from the vehicle from an odb scanner. They say they can't diagnose the issue with out an error code and seam to be unwilling to explore the issue further. Most recently we've purchased our own odb scanner to try to gather any error codes because the Jeep dealer doesn't seam to want to investigate further without us gathering error codes for them. Today we drove the car for about 45min on moderately hilly terrain at around 60mph and produced three separate overheating / low oil pressure error incidents while the odb scanner was plugged in. The odb did not indicate an error code on any of the three incidents. We are frustrated because Jeep and their dealers have left us in a situation where we have a dysfunctional vehicle and seam to be unwilling to take reasonable measures to resolve the problem.

This is the 3rd time the Jeep wagooner has "bricked up. " the vehicle will shut off without notice and lose all power, the emergency brake comes on and stops vehicle abruptly. This poses safety risk to driver passengers and surrounding vehicles. The car will not be able to be restarted for 30 secs. Once car is restarted, dash lights flash everywhere and car loses power steering. This happen 1st time 2 weeks after I bought a brand new 2024 Jeep Wagoneer. I took it to dealer and they told me it was defective battery. They replaced battery, it has now done it two more times. I took it to dealer again and they once again claim it was defective battery again. 2 defective batteries in 18 mos of new car? there is something else going on w/electrical system in this car that drains batteries and abruptly shuts off vehicle.

On 10/27/25, the thermostat on my Wagoneer exploded. It was supposedly repaired on 10/30/25. I read in the Wagoneers forum that the thermostat is a common issue, but it could be the result of engine problems. On 2/4/26, I took my vehicle in for a routine oil change. I didn't drive the vehicle for a few days. On 2/7/26, I was driving and received an error message stating max engine oil level exceeded. Immediate service required. I returned it to the dealer to fix that issue. On 2/15/26, I noticed that my engine sounded louder than normal and by 2/16/26, the check engine light was on. On 2/18/26, I received an error message saying the engine temperature was too hot. I took it back to the dealership where it is today. I believe the Wagoneers have faulty engines that need to be recalled.

During normal driving in temperatures below approximately 20–27°f, the vehicle began losing electrical charge as indicated by the malfunction indicator light (mil) and battery warning message. While my wife was attempting to return home, multiple vehicle systems progressively shut down, including electric power steering, abs, auto-leveling suspension, and lane departure assistance. As she was pulling into our driveway, the vehicle completely shut off, resulting in total loss of propulsion and power steering. The vehicle had to be towed to the dealership. This was the second occurrence of this failure. A third incident occurred the following day under similar temperature conditions. During that event, mil and battery warnings appeared again during normal driving. She was able to reach our driveway before complete shutdown occurred. On the most recent incident, the following diagnostic trouble codes were present: p0eec, p1618, p0008, and u0111. These are the same codes that were recorded during the previous two incidents. After the first two failures, kernersville Dodge stated the issue had been repaired and charged us for the repairs. The same failure condition has now reoccurred. This failure results in sudden loss of propulsion and loss of power steering while driving, creating a significant safety hazard.

My 2022 Wagoneer has stalled out 3 times at intersections as a result of the automatic start/stop. This is extremely dangerous! I have been stranded in the intersection 2 out of the 3 times until I was able to turn off/on the vehicle and trouble shoot it.

This complaint involves a 2023 Jeep grand Wagoneer l series iii, a full-size luxury SUV. The vehicle has experienced repeated electrical and powertrain failures culminating in complete loss of propulsion. On 01/22/2026, while traveling approximately 45–50 mph, the vehicle abruptly shut down without warning. The engine lost power, dashboard displays went black, and multiple warning lights illuminated simultaneously. I was forced to steer to the shoulder while a trailing vehicle had to swerve off the roadway to avoid a collision. This was a near-miss event and represents a serious safety hazard involving sudden loss of motive power at highway speed. Prior to that event, the vehicle had already stalled at a traffic light and had exhibited repeated check engine warnings, low-voltage faults, and module communication errors. The servicing dealer documented multiple diagnostic trouble codes affecting the body control module (bcm), ignition system control module (iscm), and powertrain control module (pcm). Manufacturer technical service bulletin software updates were applied in attempts to correct the issue. Despite these interventions, the electrical instability persisted. On 02/12/2026, only days after an auxiliary battery replacement intended to address voltage concerns, the vehicle would not start and required towing to the dealership at my expense. Additional fault codes are currently under review. The vehicle is also subject to an open recall with no remedy available, and the power running board motor has failed with replacement parts unavailable. This pattern of electrical failure, sudden shutdown in motion, and inability to reliably start presents an ongoing and unacceptable safety risk to occupants and surrounding motorists. The vehicle is available for inspection and has been repeatedly evaluated by an authorized dealer.

I wes driving and the over heat light came on in pulled over and had car towed to dealer. The dealer pulled the report and they said I needed a new engine and that I drove 40 miles in limp mode. There was no lights or indicators that there was an issue until the car overheated in that time it was only drove 3 miles. They cannot pinpoint when the light would ha e turned on and now I am stuck with a broken engine that stelantis is refusing warranty coverage but the car failed to alert me there was an issue.

We purchased a Jeep Wagoneer l from liberty Jeep in libertyville, IL in may of 2024 and have had issues since. The first issue was on August 25th 2024 when I was driving my vehicle it stopped in the middle of the road and turned off. I had to turn my car back on and thankfully was only a block away and drive it to my driveway with the steering stiff the whole way. After this, the Jeep had to come tow my car on August 26th. There was no warning until after it happened. Dealer had the car for one day and then said to come get it on August 27th it was fixed. My husband went to pick it up and as soon as he drove away the engine light went back on. So he turned around and brought it back in. It was in the shop from the 27th-sept 13 2024. They said it was a catalytic converter that needed to be replaced. Since purchasing the vehicle the trunk had never fully worked. We would always need to mess with it to open or close. On Nov 1 2024 the car was brought in for trunk repair. It was there until Nov 6th 2024. Well they said they fixed it and then in Feb 19 2025 it was brought back in again for the trunk. It stayed in the shop till March 4th 2025 for trunk repair. They said they fixed it again. November 3rd 2025 car was brought back in for stiff steering. When I went to turn the car steering went stiff and I couldn’t turn. I had my daughter and her three friends in the car. On top of that the navigation screen was freezing and the camera’s weren’t working. They said it needed updates with the technology and all was good. On Dec 14th 2025 the trunk wouldn’t close. It would open when I was driving my 3 kids in the car. I had to have my [xxx] son sit in the trunk to hold the trunk closed so I could get us home. Jan 17th 2026 I would be at a stop light and my car would alert me to put the car in park, turn car on and off then put it in drive then it would say abs service. This happened on a highway at a light multiple times. Someone could seriously be injured. Information redacted pursuant to the freedom of information act.

The contact owns a 2022 Jeep Wagoneer. The contact stated that while her husband was driving at approximately 10 mph, the vehicle stalled, and smoke was coming from under the hood. The contact stated that the smoke had also entered the passenger cabin. The contact stated that her husband had not mentioned whether any warnings had illuminated. The contact stated that when she arrived to pick him up, the fire was extinguished. The fire damage was confined to the engine compartment. The vehicle was towed to a dealer, but it was not a manufacturer dealer. The vehicle was diagnosed, and it was determined that the generator and the start/stop battery had caught fire and needed to be replaced. The contact was advised that the battery was on national back order. The vehicle was not repaired. The contact stated that she had searched online and associated the failure with an active NHTSA national action number: pe24018 (electrical system, hybrid propulsion system, engine, engine and engine cooling). The manufacturer was not informed of the failure. The failure mileage was approximately 90,000.

My 2024 Jeep Wagoneer series 2 frequently stalls while coming out of idle, such as at traffic lights. This is not the auto stop-start feature and happens whether or not auto stop-start is deactivated. Usually, after being by stopped, as I am getting ready to start moving again, the vehicle will slightly rev or try to lurch forward before stalling out. This turns the engine off, throws the car into park, and activates my e-brake. It happens before I press the accelerator so the car is not moving more than a mile or two an hour. This problem is dangerous because it creates a risk of accidents with other vehicles. When the car stalls in this way, I must confirm the car is in park, press the brake, restart the engine, deactivate the e-brake, and shift the car into drive before proceeding through the intersection. This takes a few seconds and if the driver in the car behind me isn’t paying attention and think I am starting to move, he or she could rear-end me. This problem has happened more than a dozen times (so not every time I drive but frequent enough to be a pattern). It can happen when I have been driving for a while and the engine is warm. There is no way for me to predict in advance when it will happen. It can go weeks without happening or happen twice in the same day. It does not activate any dash warnings (such as service engine light or an error code) that I can see. I have taken my car into the dealership twice for idle related issues including once for this exact problem. The last time, the dealership found misfires on all cylinders, both catalytic converters coming apart from the inside and 02 sensors that had melted from overheating. The dealership replaced all of this. My vehicle still stalled on the way home from the dealership. This time, I detected a strong rubber or plastic burning odor when I got home. The vehicle has less than 12,000 miles on it and was bought new less than a year ago. I attach last repair invoice.

Vehicle shut-off while driving. Electrical failure due to voltage issue with hybrid (etorque) system. Los off power while driving vehicle on roadway with potential loss of control. Vehicle taken to dealership and diagnosed with failure of hybrid battery. During my ownership of the vehicle I've had to replace the primary battery 3 times due to ongoing electrical problems with this engine.

On two separate occasions within 2 months of each other, the low battery/voltage warning appeared and shortly thereafter, every warning light in the dash came on and various messages appeared on screen stating that there were power/electrical issues. The car then shut down and died while in motion. Extremely dangerous as in the first instance, the vehicle was in the white mountains region of new hampshire (on a main road, rt. 16), with no cell reception, cold weather, and at night, leaving us stranded. The second occasion happened on a busy highway with my wife and young daughter in the car. We were able to get off the highway when the warning lights came on; however, the car died in downtown boston, at night, in the winter (December). The first time this happened, the car was towed, a "software update" was done, and we were back on the road. Then less than 2 months later, the same thing happened, and is this time diagnosed as the etorque motor. There is an open NHTSA investigation for this exact issue. Investigation:pe24018.

Repeated failures of electrical system of Wagoneer; vehicle towed to dealer who made some repairs, only for vehicle to fail again. Batteries fully replaced, issue got worse. Safety concern as vehicle will randomly not start even when traveling. Error messages with electrical shorts, failure of entertainment system.

Speedometer read zero while driving on the interstate and rpms felt as if they were off. New electrical cluster and new battery by Jeep have already been replaced claiming it would resolve this issue.

Hi, I need to bring my 2022 Wagoneer back in for service. I was just in the shop a few days ago for a persistent check engine light, and the issue has returned. The check engine light came back on four days after I picked up the vehicle. This morning the vehicle stalled twice at a complete stop. The front headlights flickered and the engine shut off, but the electronics inside stayed on. I had to press the start button to restart the engine. I also received a “start/stop unavailable” message. Because this is now a repeat failure, combined with a safety-related stall, I need the vehicle fully rechecked for: ess/start-stop system malfunction auxiliary battery condition battery current sensor bms/charging system pcm software updates any tsbs related to stalling or ess on the 2022 Wagoneer please document this as a repeat repair attempt, and if needed, I would like this escalated to a stellantis case manager since the issue is safety-related and occurred immediately after a previous repair. Please let me know the earliest available appointment. Thank you.

The Wagoneer with 20,000 miles very suddenly started to overheat, then quickly redlined on the dash board. Car shut down at dark night intersection. Needed to be towed to dealer. Dealer diagnosed that the engine needs to be replaced. Wtf. Waiting for Jeep claims rep to contact me. Case # 94698805. No word on eta of replacement engine. Expecting a long term rental car. Not happy I'm financing at $800 per month car in shop for who knows how long. Dealer claims they have 2 other Wagoneers on the lot with same engine verdict. Is there a buy back policy available? lol.

About 45 minutes into a drive, vehicle bogged down. Dash started flashed high coolant theme then immediately after got an alert for low oil pressure. Immediately pulled over to the side of the road and shut the vehicle off. Took almost an hour for vehicle to cool down enough to check coolant level. Level was completely gone. Very minimal level in the reservoir. Levels were just checked at a service appointment not even 2 weeks ago. No signs of any leaks on the floor inside the building my vehicle is parked in. Had vehicle towed to dealership and the thermostat failed according to shop tech. Which is a very common issue for 2022-2024 Wagoneers. And have only been issued as a TSB instead of a recall so manufacturer isn’t responsible to cover this continued problem. A huge safety concern for a vehicle to overheat leaving the owner stranded. Fearful to drive my vehicle long distances with the possibility this can happen again and possibly damage my motor.

The thermostat failed prematurely. Car is less than 2 years old and 37,679 miles. About 37,600 at the time of incident. The engine overheated and the car states to pull over immediately. The manual states roughly that permanent engine damage can result so the driver is forced to pull over regardless of condition. I was on a highway with very narrow shoulders with family, two parents and five children. A TSB exists but a recall should be mandated. Https://static. Nhtsa. Gov/odi/tsbs/2025/mc-11016248-0001.

Vehicle speedometer has randomly blacked out on numerous occasions not allowing me to see any of my gauges. While driving on the interstate and merging the vehicle has stalled and rpms stay stagnant yet you can hear the engine revving & then it acts like it will catch up. While driving up hill the vehicle began to stall almost like it was towing something when it was not. Back up camera has failed to turn on (resolved its self after I restarted the car). When I take it into the dealer error codes never seem to pop for these issues even though it tells me to see dealer, and read manual for proper oil and fuel usage. It’s like it has a mind of its own and it worries me to continue driving my three children around when electrical issues randomly happen every month or so & it needs constant updating. Both batteries have been replaced due to these issues draining the life out of them.

While driving the vehicle the oil engine light came on as well as a front collision warning lamp. The car then would not go into a higher gear. The air condition shut off and the car started making an electric type of noise and started slowing down and eventually stopped leaving myself and my two children stranded. This put both myself and my two children at risk. We had to get transportation home and get the car towed to the dealership and they confirmed that it is a malfunction of the thermostat which they relayed is a known issue with this model of car and its engine. There has been a recall with Jeep, but only with a portion of its vehicles and my VIN was not included.

Abs and stability control lights came on and I immediately lost braking pressure within 100 yards of warning lights and could not stop the vehicle and drove through a stop light. Fortunately there were no cars in the intersection. I also have had steering warning light as well as engine warning light. My Wagoneer’s engine stumbled and put itself in park at a stop light in another issue with the vehicle. The loss of braking force is most concerning safety issue to me. My car is only 4 days old and has already had numerous issues.

While driving in my neighborhood, the car randomly shut itself off. The car was beeping and a message on the screen said “shift into park. ” once I came to a full stop, the car put itself into park and shut off completely.

The vehicle indicated to stop and pull over when attempting to start it in the garage, it was not moving. It made a terrible grinding noise. Towed to the dealer with a failed battery and need to replace the motor generator unit (mgu), part of its etorque mild-hybrid system. The part is on back order for more than 45 days as there are more than 282 failures reported. This is a 2022 Jeep Wagoneer that the dealership is saying is out of warranty and will charge me $4,000 to fix.

Vehicle runs hot due to faulty thermostat. This is a very common and known issue but Jeep refuses to replace it unless it runs hot and dies. Hundereds or thousands of the 3. 0l Wagoneer have had this issue. It is potentially dangerous as it can leave you stranded in the roadway in traffic. I attempted to get mine replaced proactively due to it being a well known problem and opened 2 custom complaint cases with Jeep. Both times I was told it must fail, run hot and leave me stranded to get it repaired under warranty. Well, just as I assumed it would, it did and left me stranded in the middle of the roadway.

The thermostat failed, causing the vehicle to overheat and die on a us highway with multiple passengers inside. The vehicle subsequently needed to be towed to the dealer for service. This is a known issue but Jeep has not issued a recall. There is a customer satisfaction campaign (csn 26b) in regard to thermostat failure, but this VIN has not been included, despite having the same engine/year known to have a defective thermostat. The overheating was a safety issue that came on suddenly and stranded the driver and passengers away from home. The warning light for engine temperature came on within a minute of the engine shutting down leaving little time to park safely along the highway.

For the third summer in a row, this vehicle has had a "hybrid/battery/engine" issue which has caused the vehicle to stop in the middle of traffic, specifically at start/stop intersections during high traffic times - the first time was on a vacation road trip about 600 miles away from home, the second time was in town while we had our three kids in the vehicle, and this most recent time thankfully I was alone driving home from work in rush hour. The vehicle shuts off, battery and check engine lights are illuminated and the vehicle must be stopped, restarted, and turned back on in order to move away from the middle of traffic. This is the third incident of this happening with Jeep warranty covering the first two repairs due to it being the hybrid/battery system. I am now waiting for two weeks before the dealer can even diagnoze the issue to undrstand what our next steps might be.

This vehicle has presented a myriad of electrical problems as follows: 1. Glitching in the central display panel. Slow to turn on, flickers at times. 2. Alm (active lane management) system randomly and suddenly turning off. Often unable to turn the alm system back on while driving. The same issue with the adaptive cruise control system. 3. Vehicle sensors showing "unavailable" on the driver's display screen. 4. Vehicle was completely dead due to both batteries dying (main and auxillary) 5. Engine ran hot after a short period of time. Temperature reached as high as 253 degrees, then the engine overheating sign came on, followed by low oil pressure notification. Oil pressure dropped to at least 21 psi 6. There were no warning messages prior to any of these incidents occurring. 7. Auto emergency braking (aeb) would randomly engage for no apparent reason. 8. Alm unavailable service required message would randomly show up. 9. Front passenger screen would not come on, when the screen had seldomly been used. 10. The engine jumps every so often while driving. This is unrelated to the engine automatice stop feature when the vehicle is stopped. 11. A/c system is faulty. The "auto" button does not automatically adjuster the temperature or the fan speed when it is in use. I've had this issue since I purchased the vehicle. Reported to dealership more than once and it's still unresolved. 12. Driver's side window will remain stuck in the down position after window has been lowered. You have to turn the vehicle off and on for this to reset and window starts to operate again. Dealership cannot duplicate and this has happened more than once. 13. Stop/start not ready engine temperature too low message would randomly pop up at times. 14. When engine cranked, various dislay signs appeared on the driver's panel and would not allow me to use the brakes. 15. The vehicle has been in the shop since July 11th. No loaner vehicle was provided. Incidents cover various dates.

While driving at highway speeds, the Jeep suddenly downshifted, revved up a ton, and threw overheat and low oil warnings. The head gasket likely almost blew, we were very close to losing control of the vehicle. After googling, I discovered that this is a problem that Jeep is aware dozens of reports online over the last two years, and the dealerships have been buying them back and claiming it's just a thermostat problem rather than issuing a recall for what is obviously a very serious design flaw and safety issue.

The e torque system needs replaced and the part has been on backorder for months. The dealer has no idea when the new part will be available and may be up to 7 months. The vehicle is loud which is what prompted us to take it in for evaluation. We had an incident where the vehicle while in reverse and it abruptly stopped and the emergency brake was on. It would not let me move my vehicle without turning it off and back on to allow me to continue reversing.
