2023 Jeep Wagoneer Powertrain & Transmission Problems

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.

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.

Vehicle on 4 occasions resulting in 2 transmission replacements, has a Transmission Control Module malfunction resulting in the vehicle unable to shift out of 1st gear. NOTE THIS HAPPENS WHILE DRIVING. This is a HUGE safety issue that the manufacturer is refusing to acknowledge.

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.

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.

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.

While at a stop light, with start/stop active, I released the brake, which should have "reactivated" the car. Instead, it shut down. I got a quick transmission service error on the dash. Once I put the car in park and turned it off and then on again, it functioned properly. I. The meantime I was being honked at from everyone missing the green light behind me.

Engine overheated and oil pressure low warnings came on suddenly and lost power. I had my two grandkids and was on a dark country road with ditches and no shoulders. Pulled off at the next cross street to get to safety. Was stranded at night in a rural area with my [XXX] and [XXX]. Had to have vehicle towed and wait for someone to pick us up. Thermostat failed, which is a known problem but my VIN wasn’t listed on the 26b notice. Engine was damaged beyond repair. It took three weeks for them to replace the engine. The morning after I picked up the Wagon, the brake warning light came on when the grandkids were in it again. The dealership told me to have it towed. They said they spilled brake fluid when they replaced the engine and refilled it. I paid nearly 100k for this unsafe car! There is no excuse for not replacing a cheap $50 thermostat to avoid this issue. Why haven’t they issued a recall?

This Jeep has gone back to the dealership 3 times for dangerous Undrivability, twice on the back of a tow truck, and third time retrieved by the dealer for repair. It has endangered my family on multiple occasions, each for a different reason, making this car unsafe to have my family drive in. It is less than one year old. Only 1 month after purchasing, it died in a parking lot with my family in the car. It had to be put on a flatbed back to the dealer for a computer replacement. The second time, it died in my driveway and again had to be brought on a flatbed to the dealer. The third incident was the most dangerous and the incident that must be flagged. With my kids in the car, my wife came to a stop sign. The car shook and jittered, the entertainment system went out, and the headlights flashed. A driver at the intersection thought my wife had "flashed the lights" and proceeded into the intersection, nearly causing an accident. I had the dealership come and get it, they applied a fix for the engine start-stop recall and said that likely fixed it. This car is unreliable and unsafe, and Jeep refuses to buyback the car, telling me only to start arbitration. They have refused to even give me a manager, and not returned all my calls.

On the highway and interstate highway, during stop in stop-and-go traffic, the vehicle randomly automatically shifts into park and apply the parking brakes when attempting to accelerate from standstill. This only happens when you try to move again after stopping, and the vehicle is shifted into park in the most inopportune times. It requires you not only to shift it back to drive with your right hand, and reaching under the dash with your left hand to release the parking brake. When task saturated during an emergency it is highly likely to cause an accident, such as turning left onto a divided country highway while the car is temporally stopped between the two highways. No dealership involvement yet. This occurs randomly, and I have not been able to find a way to replicate it at will. This has occurred more than a dozen of times. Warning light on the dash stating shifting the car into park, and audible beep. Dangerous because it occurs randomly on a highway. Unsure if it's related to automatic engine stopping, or adaptive cruise control.

I bought this vehicle used form Carmax, <12000 miles. Drove about 12 miles, when while parking I noticed the car stopped and asked to start engine and engage gear again. Didn't think much of it. Then started driving again and the check engine light turned on. There are lots of reports of wagoneers with engine light problems (in fact we had test driven a different one with both check engine and transmission lights on which for obvious reasons didn't buy). I reported to Carmax. Finished my drive and stayed idle for a while trying to see if there were any settings that may be responsible, but the engine was stuttering, almost shutting off, with the entire thing, even the driving lights shutting off intermittently. The following day I took the vehicle for a check at Carmax, and while slowing at an intersection to let a school bus pass, the car completely shut down. I started again and drove very carefully. They could not diagnose the problem at Carmax and they wanted to send to Jeep. I eventually returned the vehicle. I had seen reports of many problems with the 2022 Wagoneer model, but none about the 2023, but I now came across forums where people even describe complete shutdowns of the vehicle while driving in the highway. While I returned the vehicle, I think these serious engine and system failures could endanger others on the road. I took videos and pictures of the problems. Happy to share if you request them.

Service brakes because the brakes engaged on their own while reversing, with no obstruction present. Power Train because the transmission downshifting unexpectedly in traffic, forcing us to pull over on the highway and restart the engine. Electrical because the rear camera blackouts while reversing fall under "back over prevention" and sometimes also electrical system. Engine because the oil pump solenoid failure with a complete oil pump replacement occurred. It's also an engine lubrication system failure which can cause catastrophic engine damage and loss of power.

I am writing to formally request your assistance regarding my 2023 Jeep Wagoneer— [XXX] — which has experienced extensive and repeated mechanical failures that have placed my safety—and the safety of my young children—in serious jeopardy. This was purchased new. In December, I went through arbitration regarding these issues. Unfortunately, I was unsuccessful, largely because I did not have legal representation and was unable to adequately represent myself. Since that time, the problems have continued, and the vehicle remains dangerous and unreliable. I am fearful this vehicle is going to end up costing our family our lives. One of the most recent alarming incidents resulted in me sustaining a black eye due to unexpected, random braking— this was in late July. In addition, there have been ongoing and unresolved issues with the four-wheel-drive system, despite nine separate repair attempts. The rear differential has been replaced four times, and the front transfer case has also been replaced—yet the problems persist. To date, my vehicle has undergone over 40 documented repair attempts and has spent more than 250 days in the dealership for repairs. Despite these efforts, it is clear that the vehicle cannot be properly repaired and continues to pose a serious risk. Given the severity, frequency, and duration of these failures, I believe this case warrants urgent attention under Arkansas consumer protection and lemon law statutes. I respectfully request that your office review my case and take any appropriate actions to ensure my family’s safety and my rights as a consumer. I can provide full service records, repair invoices, and documentation from the arbitration process upon request. Thank you for your time and attention to this matter. I look forward to your prompt response. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
