I am writing regarding my 2021 Jeep Gladiator Mojave, which recently suffered engine damage due to a faulty head gasket. I understand the vehicle is approximately 5,000 miles over the 60,000-mile warranty; however, I believe this issue should not be my financial responsibility given the circumstances. At around 60,000 miles, I brought my Jeep in for a full service and inspection to ensure it was in top condition. I was informed at that time that everything looked fine and that there were no issues to address. Since then, I’ve continued to maintain the vehicle properly and drive it with care. The sudden head gasket failure, which ultimately led to engine damage, came as a complete surprise. This situation has been extremely difficult — not only because of the unexpected cost, but also because this Jeep was meant to be my long-term vehicle. My family and I have been loyal Mopar customers for years, and I’ve always trusted in the quality and reliability of your vehicles and service network. Given that I sought professional service and maintenance through authorized channels, and that no issues were identified at the time, I kindly request that Mopar consider a goodwill repair or assistance. I don’t believe it’s fair to be held financially responsible for a mechanical failure that likely existed but went undetected during a recent inspection. I’m grateful that nothing happened to me on the road, as I was unaware of the developing problem under the hood. I truly hope Mopar can stand behind its reputation for integrity, safety, and customer care by helping me through this situation. Thank you for your time, understanding, and continued support. I look forward to hearing from you soon.

The contact stated that while driving at 60 MPH, there was an alarming amount of white smoke emanating from the engine compartment and permeating the interior of the vehicle, prompting the contact to pull over to the shoulder of the roadway and evacuate the vehicle. Moments later, the entire front of the vehicle was completely engulfed in flames. Local Emergency Services arrived on the scene and were able to extinguish the fire. During the failure several unknown warning lights were illuminated. The vehicle was towed to the residence and deemed a total loss by the Insurance provider. A fire report was filed and preliminary findings on the potential cause of the fire were provided but the contact was unaware of the cause. A Police report was filed, and injuries were reported. The contact's father suffered minor burns to both hands but had not sought medical attention. The manufacturer was notified of the failure, a case was opened, and the vehicle was retrieved for inspection.

Hi - So my 2021 Jeep gladiator has 2 batteries. The battery that controls the auto start-stop system failed (while driving). I was at a light on a busy road and the auto stop/start kicked in at a light but because of the failed second battery with no warning, my Jeep died would not start backup and I was unable to even get it into neutral. So I was forced to sit in heavy traffic until the wrecker came. My complaint it why no warning and why did it go into auto stop mode when the battery was in a failed situation.

My vehicle has about 17,000 miles. Both key fobs are failing to connect with the vehicle. The batteries have been checked by the dealership to determine the fobs are in working order. Without having the fob work, I am unable to unlock my doors or start the engine. Thankfully, learnng my fobs were not connecting occured while in my garage at my home. However, if this occured while away from home, or at night, I would have been stranded with no access to drive the vehicle. My Gladiator will have to be towed to the dealership now to get this resolved.

Denver, COCrash1 injured

Under heavy breaking the rear wheels of my vehicle lifted off of the pavement. This loss of traction and shift in weight resulted in a head on collision with a vehicle in the opposite lane of traffic. After the accident I discover that the suspension for my vehicle was incorrect to the level that FCA released a TSB regarding the issue. The suspension that was equipped with the vehicle was designed for the gasoline motor and the weight associated with that motor. My vehicle has the diesel motor (approximately 600lbs heavier) along with factory equipped steel bumpers adding additional weight. This factory design failure created a vehicle that could not perform as designed and as I found out via an automotive accident, a vehicle that under heavy breaking can lift its rear wheels off of the ground.

On 3 different occasions the acceleration got stuck and increased speed. I pressed the brake over and over and the Jeep would NOT reduce speed or slow down for what ranged between 30 - 45 seconds. Had there been a vehicle directly in front of me I would have slammed into the vehicle. If I had been trying to stop at an intersection I would not have been able to stop. I had my child in the car two out of the three times this has occurred. The dealership states that they have not had any complaints of this occurring and could not replicate it during the few minutes they drove it and do not seem to be concerned that this issue could seriously injure or kill me, my child, or others. This is a SERIOUS issue that should be addressed immediately.

I was driving the vehicle, while towing a 5000lb trailer (vehicle tow rating is 6000lb), up a 4-5% grade at 4000'-6000' elevation, with ambient temperature around 80 degrees, and the vehicle unexpectedly derated / limited speed to approx 45 mph with no warning indicators on the vehicle. I had a number of cars and semi trucks behind me, and so I unexpectedly needed to find a safe place to pull over, which was limited due to the road conditions. I travel in areas frequented by semi trucks with limited shoulders. If I had not found a pull-out, this could have been dangerous. This appears to be an issue countered by a number of Jeep Gladiator Diesel owners, relating to either engine oil temperature too high, or EGT temp too high when towing uphill.

While towing a trailer the vehicle suddenly reduces power to less than half and multiple check engine lights appear. This seems to happen only when outside temperatures are above 80f. I went from going 65mph to 45mph within 1/4 mile which caused sudden traffic issues behind me. I have had the vehicle to the dealer multiple times and they do not find anything even though there are multiple engine lights. I have had it happen a over 8 times in 1 year. I also have a co-worker that has had the same issue.

3.0 EcoDiesel in the Jeep Gladiator has cooling issues. Thousands of users affected and discussing on forums and on Facebook groups but the manufacturer is unwilling to fix. Core of the issue is that the engine was altered in the Gladiator and Wrangler over previous installations in the Ram and Grand Cherokee by removing oil coolers and a larger oil pan, which has resulted in high oil temps. At 265 degrees (which is accomplished easily during the summer with a trailer UNDER the tow rating), the engine starts derating and limp mode. The aftermarket community has tested everything ... removing hoods, fenders different cooling solutions, etc and nothing is working at the moment other than aftermarket solutions to cool the oil (which are negligible at best at the moment due to the space constraints imposed by the engine being quite large in the engine bay not not substantial room for a larger oil pan and external cooler). Chrysler should have put more work in to the design, or not sold the EcoDiesel in the vehicle.
