2023 Jeep Wagoneer

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.

Vehicle: 2023 Jeep Wagoneer Mileage at time of incident: 43,400 miles Component: Engine Cooling System / Thermostat Incident Description: This vehicle has experienced two separate thermostat failures since purchase. The first failure occurred the day after I purchased the vehicle, in April 2024, at only 104 miles. This time the vehicle overheated /stall pattern even after confirming coolant was at a sufficient level. The second failure occurred on Monday, June 22, 2026, at 43,400 miles. While driving with my wife, son, and son's friend as passengers, the temperature warning indicator activated, signaling an engine overheating condition. Shortly after, the engine lost power and stalled completely while the vehicle was in the middle of a busy intersection. With the engine off, I had no power assist for steering or braking, which made it extremely difficult to maneuver the vehicle out of the path of oncoming traffic. My family and I were nearly struck by other vehicles while attempting to get the disabled Wagoneer clear of the intersection. The recurrence of this failure at relatively low mileage (43,400 miles on a 2023 model) indicates a potential design or manufacturing defect in the cooling system, not an isolated incident. The second failure resulted in a complete loss of engine power in active traffic, creating an immediate safety hazard to my passengers and to other drivers on the road. Repair history: Failure #1: April 2024, 104 miles Failure #2: June 22, 2026, 43,400 miles Cost of most recent repair: Approximately $2,000

The vehicle will severely vibrate when traveling 60mph or higher. Faster speeds increase the vibration intensity. I used a vibration meter on the steering wheel and drove on a smooth highway. Multiple tests/results were all similar, the vibration meter would register up to 10.3 and avg in the mid 4s and 5s. A 5.8 equates to a Level VI Strong Earthquake on the Mercalli Intensity Scale. The vibration is so violent the steering wheel shakes uncontrollably causing a strong fear of losing control. We live in rural Nevada with open desert and spotty cell service for most of the drive from Pahrump NV to Las Vegas. We were afraid to drive the vehicle due to the handling issues, that something happening in the middle of nowhere. Jeep customer support denied, obstructed and overall refused to help. Was assigned to several agents and supervisors and after filing the initial report, message requests were rarely returned. I was ultimately told by Customer Care, “it was my problem not Jeeps”. The first dealership I went to refused to look at the car unless I paid them for unnecessary work I then went back to Jeep Only in Las Vegas (where I purchased vehicle) and they quickly acknowledged the severe vibration issue was a common problem and they have serviced this problem on many other Wagoneer’s in the past. I worked with Evan the Service Advisor and Tigh Pesicka the Service Manager and they assured me the problem was with Jeep’s paring of the Bridgestone Dueler H/L Alenza tire and the Wagoneer. The Bridgestone was a passenger tire and the Wagoneer due to its weight needed light truck rated tires. Evan at Jeep Only recommended the Continental Terrain Contact A/T tires, I purchased them and it lessened the severity of the vibration. The dealership failed to get Jeep to cover the new tire, so they said I will have to pay for them and sue Jeep for reimbursement. A quick search you will find many examples of Wagoneer Owners with the same issue.

2023 L series II Wagoneer 84,444 miles full bench 2nd and 3rd row - My family was travelling in the car and the second row driver side seat unlatched and forcefully slammed my daughter into the back of the driver seat. No aggressive driving and no warning lights on the dash. The car dinged then slammed my daughter's face into the back of the driver seat. Caused swelling and a black eye on the left side. Also caused a spinal injury on the C2 and C3 joint that we are still getting information on the issue. I am submitting this in hopes that this does not happen to someone else's family like it did mine. My family of 4 and 3 kids that are family friends. The event took place on 6-11 and I am writing this report on 6-12. No inspection has been done on the car due to still being at the hospital consulting a specialist on the spinal issue.

I submitted an issue last week for the vehicle putting itself in park while driving and loss of brakes while driving. I brought the car to an authorized dealer and they told me they fixed the issue. It is now happening again. This is a major safety concern!

On February 13, 2026, ALM [XXX] [XXX] ) sold me a 2023 Jeep Wagoneer (VIN: [XXX] ) with Federal Safety Recall 88C (NHTSA Campaign 25V-642 — rear quarter window trim detachment, road hazard risk) open and unrepaired at the time of sale. This recall was not disclosed to me during the sale process, which was conducted remotely. I discovered the open recall only after taking delivery of the vehicle. Owner notification letters for Recall 88C were mailed beginning February 19, 2026 — six days after my purchase. ALM CDJR had knowledge of this recall prior to sale and chose not to disclose it or complete the repair before delivery. The recall has since been completed by a different dealer (Farris Motor Company, Jefferson City, TN). However, ALM CDJR's sale of a vehicle with a known open federal safety recall without disclosure is a dealer compliance violation I am formally reporting to NHTSA. I have filed supporting complaints with the Georgia Attorney General's Consumer Protection Division and have documentation of this transaction on file.

I am reporting a catastrophic engine failure on a 2023 Jeep Wagoneer (VIN: [XXX] ) that occurred within 163 miles of consumer delivery, suggesting a latent manufacturing defect present at the time of sale. The vehicle was delivered February 13, 2026 at approximately 29,750 miles. Engine noise was noted the same evening. By March 10, 2026, the vehicle was grounded at Farris Motor Company [XXX] ) at 29,913 miles — 163 miles after delivery. The vehicle remains inoperable after 60+ days. Stellantis STAR Case #XXX documents the following confirmed failures: collapsed lifters, failed camshaft, damaged rockers, and scored cylinder walls. Technician notes in the official STAR Case record state the engine oil contained metal contamination so severe it "looked like paint." Borescope imaging confirmed scoring on cylinder walls. Stellantis has thus far refused to authorize a full engine replacement, instead directing the servicing dealer to replace only individually identified failed components — despite the fact that metal contamination of this severity compromises the entire lubrication circuit, including both turbochargers. The servicing dealer (Farris Motor Company) has independently advocated to Stellantis for full engine replacement and agrees the partial repair is insufficient. I am reporting this failure to NHTSA to document the defect pattern and request investigation into whether other 2023 Wagoneer vehicles with the 3.0L Hurricane engine may be experiencing similar latent valvetrain failures.

Several times, the car put itself into park while driving. Two times, the brakes failed while driving. The brake was pushed all the way to the ground, but the car would not stop.

My 2023 Jeep Wagoneer experienced a catastrophic panoramic sunroof failure while parked and unattended. The vehicle had been driven normally earlier that day with no known impact or debris strike, and I have footage from before arriving showing the roof intact. The vehicle was parked in a school parking lot for approximately 2.5 hours, and when I returned, the panoramic roof glass had spontaneously shattered. No impact event was witnessed, and there was no known object strike to the vehicle. The dealership determined the damage was caused by outside influence; however, no specific impact point or evidence of an object strike has been identified to us. Because the glass shattered unexpectedly while the vehicle was stationary, we are concerned this may represent a spontaneous tempered-glass failure and a potential safety defect.

the gauge cluster and heads up display does not activate vehicle starts and drives but there is no speedometer no tach etc

The contact owns a 2023 JEEP Wagoneer. The contact stated that while towing, the vehicle experienced a serious and recurring safety failure where the trailer lights would function for approximately five minutes before a portion of them would blackout. This failure renders towing unsafe and illegal, as it compromises visibility and traffic law compliance. The contact referenced NHTSA Campaign Number: 26E006000 (EXTERIOR LIGHTING, ELECTRICAL SYSTEM) however, the VIN was not included in the recall due to the vehicle not being within the 2024-2025 range listed on the recall notice. The vehicle was taken to the dealer on three separate occasions for the same failure. During the first visit, the dealer stated the issue was with the trailers; however, the contact paid for independent inspections that confirmed both trailers were in proper working order. During the second visit, the dealer performed a software update, but the failure persisted. During the third visit, the dealer diagnosed the issue as a known manufacturer software defect with no current resolution available. The vehicle was not repaired, due to no other options of repair besides a recall. The manufacturer has been notified of the failure. The failure mileage was 25,335.

I scheduled an appointment Genes Chrysler Jeep Dodge RAM service department in Fairbanks, AK on February 13, 2026 to perform all recalls on my vehicle. This appointment was made almost a month out to ensure I had the day off to be able to drop off my vehicle and have them keep it for the remainder of the day. The service department informed me before closing time around 1700 that my vehicle was ready for pick up. In the next few weeks, I was still receiving recall information in the mail. I called Genes again and spoke with a representative who checked the system for me and she assured me that recalls were completed but it takes time for the system to update. I took her word for it. My vehicle is currently in service at Genes now for other issues and I called Stellantis to open a case for the delays. Per their regulation, when a member calls, they let them know what recalls is still against their vehicle, they assured me that my recalls was still open. I wrote an email to Genes manager requesting to answer me via email as proof that recalls were performed on my vehicle, but he did not address my question to this day. I have attached the receipt of the workorder on Feb 13 that states recalls were performed on my vehicle. I am also attaching the email traffic from Genes regarding my follow up question. There are other correspondence in this email, but I have highlighted my email that I sent on May 4th and attached the PDF with the email.

Vehicle started up on its own and continued to run. Key fob was laying on a night stand. No messages were displayed in car. I was able to turn it off.

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

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.

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.

On two occasions now, the car will start and all other electronic screens will turn on and be normal, but the driver screen behind the steering wheel does not. We can put the car in drive and it operates normal but the screen only shows the display to "press brake and push button to start" the button icon and odometer mileage. Everything else is blank. We have no way of knowing the speed/rpm/fuel/battery/etc. I have video of it while driving and and photo when parked. I am contacting the dealership but wanted to report my concern.

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 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.
