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.

While driving at low speed, the vehicle suddenly shut down completely without any warning. The engine lost power while I was cruising, causing the vehicle to stop responding. On separate occasions, the vehicle has also shut off while idling. This condition creates a serious safety concern because the vehicle can stall unexpectedly in traffic, increasing the risk of a collision. The issue has occurred multiple times and appears to be happening everytime I drive the vehicle. It started Nov of 2025 up to now dealership cannot fix the problem.

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.

We were driving and approaching a stop light at a major intersection when the vehicle stalled out. We heard it sputter at first and then cut off. We tried multiple times to restart, but to no avail—just kept sputtering. This is the second time this has happened. The first time was also reported to NHTSA, and I was driving alone and ascending a colorado mountain when it stalled out. Thankfully, both times, we were able to remain safe; however, this is a huge problem as both times we were on major roads.

While driving my 2023 Jeep Wagoneer on 12 Jun 2025 I stopped at an intersection preparing to make a right turn. When I took my foot off the brake and prepared to accelerate, the vehicle abruptly turned off and lost all power and control. The instrument cluster said to shift to park in order to restart. I was able to restart the vehicle and drove it immediately to the Jeep dealership service. The dealership immediately scanned it, but was unable to diagnose the issue. We drove the vehicle back to our home and are now afraid to drive it due to concern over the vehicle shutting down while driving.

The contact owns a 2023 Jeep Wagoneer. The contact stated that several unknown lights on the instrument cluster were illuminated and flashing. Additionally, the headlights were flashing, and the camera screen was blank. The contact stated that while depressing the brake pedal, additional force was needed to stop the vehicle. There was an abnormal horn sound detected. The contact stated that the engine overheated and the vehicle stalled. The vehicle was jump-started. The contact was locked out on several occasions. The contact stated that the third-row seat had folded her child up while parental controls were enabled. The vehicle was taken to the local dealer, where the battery was replaced, but the failure recurred. The vehicle was taken to another local dealer, charbonneau car center (346 1st street west dickinson, nd 58601); who was unable to duplicate the failure. The vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 40,000.

Breaks, engine and transmission as well as radio and screen (electrical).

The vehicle is stalling. The vehicle has been to the dealership three times and they cannot figure out the issue. The vehicle has only been inspected by dealership. There was no warning lamps or message of this issue. The issues started two weeks after we purchased the vehicle.

Leaving for work this morning and reversed out of parking spot, tried to pull out onto a busy road and almost died. The car just kinda rolled forward a bit and would not accelerate or do anything! the ignition switch was blinking. I could not reverse or go forward or put it in park, the gear shifter lights were all blinking as well. I couldn’t shut the car off to restart it. I could not change gears or go anywhere but sit in the middle of an intersection with cars approaching me at a high rate of speed. It took approx 2 min for the car to do anything. It finally allowed me to shut it off and restart. Check engine light on. I reversed back into the parking lot I had exited from and drove it around to make sure I could accelerate onto this road where people do 70mph. I’m extremely lucky I did not get t-boned. I have read about this issue escalating to the car having this problem and told my dealership about this when I was having the check engine light issues mentioned below. I really do not feel safe in this car now after getting stuck in an intersection. Prior issue with Wagoneer, it’s been to the dealership at least 4x for this: bumps you back into park when you try to reverse and then the check engine light comes on. I have to shut the car off, open my door, restart, and then it’ll go into gear and check engine light remains on until I bring it in or sometimes after driving a bit it goes off itself. There was some known issue with possible problems with the transmission regulator valve so they switched that out and said that should take care of the issue. But check engine light on again. It now progressed into being completely disabled at an intersection today.

While driving at lows speeds approaching a stop light the vehicle will just shut off and shift into park. I have to hit the brakes, make sure its in park, and hit the start button, it restarts then doesn't do it until randomly later it does it again. There is a check engine light on.

Vehicle suddenly lost power and overheated while driving. Had to get towed to the dealership. Dealer advised that the thermostat had failed, which seems to be a common occurrence with these vehicles. Thermostat was replaced but continued to overheat, leading the dealer to suspect the engine was warped and in need of replacement.

My 2022 Jeep Wagoneer has a 5. 7-liter v8 equipped with etorque system. The etorque went bad and the vehicle stalled in the middle of a 4-lane highway at a busy intersection. My Jeep was completely dead, and I couldn't even turn my emergency flashers on, making this an extremely dangerous situation. I was fortunate this was during the daytime which is dangerous enough. Had it been at night, this would be even more dangerous. I had the Jeep towed to a dealership.

I was driving and the car started making a weird noise. It then started to slow, the temperature went to red and the car started beeping. It kept going slow and then just stopped in the middle of the road. I could not move and was almost hit by multiple cars.

The Wagoneer while driving twice has shut off, gone into park, and emergency break turned on. The problem is shutting off on its own while driving. This could cause a wreck obviously if happens at a higher rate of speed. Thankfully both times I was at about 5-10mph and nobody was behind me.

For the past five months, the vehicle has stalled nearly every other day, including while backing out of driveways or parking spaces and when slowing to stop. Each time, the engine suddenly shuts off without warning, the transmission automatically shifts into park, and the emergency brake engages. An engine warning light appears with a “battery fault” message. The repeated engine shutdowns and automatic braking create a serious safety risk, particularly when backing into traffic or stopping at intersections. In several instances, the vehicle would not restart for several minutes, leaving it disabled in the roadway. The vehicle has been taken twice to the authorized Jeep dealership in stonecrest, georgia, but the service department was unable to reproduce or correct the issue. The problem persists, and the “battery fault” light continues to appear intermittently. Component or system: engine and electrical system (battery and power management) availability for inspection: vehicle available upon request.

Vehicle will randomly lose all throttle power when driving and at the same time following a warning beep will flash a large red lightning bolt with the following messages: service electronic throttle control,stop/start unavailable service stop/start system, service electronic stability control and check engine light. Engine continues to run but car will not move. Once vehicle is able to be pulled over to the side of the road and turned off then cranked back up the vehicle will drive normally. Check engine light will stay on for several key cycles then it will eventually go away. This has happened at intersections and at speed on the interstate. Repair of this issue with the vehicle has been attempted 4 times and is currently at the dealership now for the 5th time and the diagnosis is that they can replace the throttle module but there are not codes pointing to that as the issue and it was stated that is is just a guess and I can then drive it and hope that it is repaired. The vehicle has been to two different dealerships for the issue as the 4th occurrence was too far away from home to get it back and it was only 319 miles between failures. The issue has not been taken seriously by the dealerships nor the customer care agents that have been contacted through the last 3 occurrences. The agent has been helpful in getting a rental or loaner to drive and delivering my vehicle back but the gravity of the problem has not been fully grasped by those examining the vehicle. The only reason this has not resulted in a crash is that each time it has occurred a space to get off the road was accessible. This will not be the case if the vehicle is continued to be driven. I did continue to drive the vehicle with the hope that the repairs would have been adequate to prevent the issue from reoccurring. This issue began in September 2024 at 30k with most recent 5th time noted below.

Dec 17, 2024 2022 Wagoneer was dropped of for service for a slight rattle in the engine. It was determined that the cams and shifters were “over-torqued” and had thrown metal shavings into the engine. This would require a full engine replacement which was conducted over the course of nearly 4 months. This is a reported and known issue/defect for Wagoneer. It was picked up March 28, 2025. On April 11, 2025 I experienced a full mechanical and/or electrical catastrophic failure while driving. The vehicle would not accelerate or brake. Multiple warnings and failures lit up the dash: service engine, oil pressure, throttle, etc. The emergency brake engaged, the engine very loudly shook, rattled and died. When trying to engage brake to put vehicle in neutral to be towed we heard a series of clicks and a pop and the engine began to smoke near drivers side. Stellantis refuses to acknowledge the recurring issues in these engines and continues to deny our buy back claim. These vehicles are dangerous. This experience violates every customer protection in this country and stellantis should be held accountable for taking millions of dollars from customers knowing this issue is recurring. We are still hoping for a positive resolution.

On April 5th, vehicle overheated while driving in city traffic. I was able to pull to side of road where vehicle shut itself off. Prior to this event I noticed sluggish engine response and ac had stopped blowing cold air. I waited about 5-10 minutes and restarted vehicle. Sat at idle for 5 minutes with out any warnings or previous indications of an issue. Then received momentary warning of low oil pressure. I shut vehicle off and had it towed to dealership. Dealership was able recreate problem during diagnosis drive. Identified faulty thermostat. The dealership stated 3 wagoners were ahead of me with similar issues and are waiting on parts. The dealership is limited on how many thermostats they can order per week. Based on parts and labor timeline I will likely be without vehicle for 3-4 weeks.

In June of 2024 the engine hot and oil pressure low light came on in the middle of a busy intersection and the car went limp had to get it towed to dealer. They replaced engine thermostat. March 18, 2025 was driving down interstate at 80 mph when wheel locked up and brakes. The power steering and brake light came on with a red exclamation point and I was unable to barely move the wheel and had to continue another mile until highway exit. If the highway curbed could have been deadly. Towed it to Jeep and they said upon checking it all looks good. Now I’m suppose to drive my five kids around and hope that never happens again with no explanation from dealer on what exactly caused it.

Immediately after getting off of the expressway on the drive to work, there is a stop light at the intersection of city streets. While sitting at the stop light, foot on the brake, the vehicle stopped running, the brake pedal went to the floor, and the service power steering warning screen was flashing and chiming. I immediately put my hazard lights on to warn oncoming traffic that I wouldn't be proceeding, because at that point the light changed to green and people behind me were letting off their brakes and rolling forward. After about 45 seconds to 1 minute, the vehicle showed a screen that said to place foot on brake and press ignition to start the vehicle. I was able to start the vehicle again, but the power steering warning light was still on. I had the vehicle towed from the street parking near my job. If the incident had happened 45 seconds prior, I'd have been still on the expressway in heavy rush hour traffic and would have been hit if my vehicle came to a dead stop or lost brake or steering control with no prior warning. The vehicle had just been serviced 2 weeks prior for thermostat failure and stalling, leaving me in an intersection. The latent defects presenting themselves on this vehicle are creating a multitude of near miss safety issues that are being minimized by stellantis and their "customer care" representatives.
