Car will shudder and shut off while slowing down. The control panel will change to saying "Push start button to run." This has happened 50+ times, including while in slower traffic on the Interstate. It is very dangerous because I am stopped suddenly in traffic and have to restart the car and put it back in gear in order to move. Car has also started and run, but the control panel remains in the "push button to start" mode while driving, so none of the control panel is available. This is dangerous because I have no idea what my speed is.

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

WHEELS — Filed 12/07/2025

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!

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.

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.

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.
