2025 Jeep Grand Cherokee

My 2025 Jeep Grand Cherokee 4xe suffered a catastrophic internal engine failure and set DTC P2338 ("Cylinder 3 Above Knock/Combustion Vibration Sensor Threshold"). Although my VIN is not included in Safety Recall 78C (NHTSA 25V-766), my vehicle experienced the same failure mode, symptoms, and diagnostic code associated with the recall. Stellantis' STAR Center reviewed the case, confirmed internal engine damage, and recommended complete engine replacement. While driving at highway speed, the vehicle suddenly lost power and entered limp mode. I was able to safely exit the highway, but this defect created a serious safety risk and could have resulted in a crash. Stellantis has already expanded the recall population after identifying additional affected vehicles. My vehicle was built during the same production period, experienced the identical failure, and has a manufacturer-confirmed engine replacement recommendation. Chrysler's XC2 program provides unlimited years/unlimited mileage engine coverage for this defect, which is linked to engine manufacturing issues. Based on the identical failure characteristics and confirmed diagnosis, I believe my vehicle is affected by the same defect and should be included in Recall 78C and the associated XC2 warranty coverage. I am submitting this complaint to request that NHTSA investigate whether additional vehicles outside the current recall population are experiencing the same defect and whether Recall 78C should be expanded to include affected vehicles such as mine.

There is a serious malfunction between the hybrid and electric systems. The engine is making a loud noise, and neither the hybrid nor electric mode functions properly. In addition, the fuel and oil refresh warning remains on, even after refueling. These issues are ongoing and substantially impair the use, value, and safety of the vehicle.On January 2, 2026, and march 8 my Jeep Grand Cherokee 4xe shut down twice while I was driving home on the freeway. This vehicle is not safe to operate under these conditions.Despite these concerns, the issues have not been resolved. Stellantis has removed 4xe models from the Jeep website due to safety concerns, recalls, and a high volume of customer complaints. At this time, there appears to be no effective remedy, and a simple software update will not correct these defects.My vehicle continues to produce an extremely loud engine noise, even while operating in hybrid mode. I am very familiar with how a Jeep should perform—this is my fifth Jeep Grand Cherokee—and I have never experienced anything like this before. Even my previous gasolineonly models operated much more quietly. In contrast, both the hybrid and gas modes on this vehicle sound like a diesel truck. Additionally, the fuel and oil warning light remains on constantly. I have contacted Jeep Customer Care multiple times, as well as the servicing dealer, and I was repeatedly told to “add more gas and continue driving the vehicle.” Despite following those instructions, the issue persists. The warning light does not turn off, the engine remains excessively loud, and the fuel consumption is unreasonable. The situation worsens in cold weather. The battery drains rapidly from 100% without explanation, even when the vehicle has been properly charged. At this point, I am genuinely afraid to charge the vehicle and even more concerned about driving it.In addition, the vehicle feels sluggish while driving and frequently does not pick up power as it should. There is a noticeable delay

During a cross country trip we exited the highway and noticed a grinding sound from our new 2025 Jeep Grand Cherokee. We then limped to a near-by Jeep dealer who diagnosed a bad transmission. We feel very lucky this did not occur on the highway as a crash may have occurred due to the manufacturer defect. The transmission has been replaced after a delay of 35 days. The mileage at the time of the incident was 3,135.

On multiple occasions, the transmission does not respond to gear changes such as moving from drive to reverse or park into drive. On those occasions, the D for drive would be blinking. More concerning and very dangerous is a lack of propulsion mid drive, the transmission would not go into gear. The engine would rev high, and it would not move forward, except by whatever momentum it originally had. This has happened to me on at least four occasions two of which I was in the left lane of three and four lane wide streets with cars passing me at high speed on the right. I needed to pull over turn the car off and then on again, which is the only way that the transmission would start working again. Sometimes the transmission would be jerky, especially after those incidents. crossing three and four lanes while people are going 50 and 60 miles an hour is a very dangerous situation when you have no power. The car is a new car. I have had it for only two months and it has been doing this intermittently the entire time. This has been at the dealer for service two times so far and has not been able to be replicated, however, I do have one incident on video. There were no warning lamps messages, and there are no error codes that are found by the dealer.

The car has a strange thump when driving around 70-75. This is always and the dealer says it’s normal, which is not true! This weird thump is now happening at lower speeds and also a weird shuddering at speeds around 25-40. Shudders are more random Also starting at about 8-10,000 miles randomly while driving highway speeds 70-75 the vehicle shudders /vibrates for about 20 seconds and then stops. I do not use lane assist so it’s not that. It feels like when you run over the rumble sticks on the highway but amplified x20. Also since almost purchase I have had several alignments because the car continuously pulls to the left. In Florida the roads crown to the right for rain water run off. If anything the car should pull to the right but it pulls to the left consistently even right after an alignment. Other complaints I’ve made are how unstable and wobbly it drives and this has gotten significantly worse to the point that the ability to maintain control of it on the highway is not pleasant and feels very unsafe Any cat that randomly shudders at highway speeds is not safe And needs to be fixed. However,14 service trips and several manufacturer complaints and still nothing… they promise things and give it a car wash instead. They are not saying much about their own product to tell me it’s running as designed. I’m tired of hearing I can’t duplicate it. Absurd excuse. At this point it’s been very scary at times… so I’m selective with where I use my vehicle. So I’ve been renting when I need to go on the highway. This is costly but at least safer for myself and others. I wish they would just fix the car

The contact owns a 2025 Jeep Grand Cherokee. The contact stated that while driving 68-69 MPH, the vehicle unexpectedly decelerated to 11 MPH and went into LIMP Mode, shifted to park, and then shut off unintendedly. The vehicle coasted off the highway safely. The gear shifter was not in park, and the message "Auto Park not Engaged" was displayed. The vehicle was towed to the local dealer, but was not diagnosed or repaired. The vehicle was previously towed to the local dealer, where it was determined that the START/STOP button needed to be replaced. The DTCs retrieved were: B1A70-09, B1A70-2A, and B1A7D01. The vehicle was repaired, but the failure persisted. The vehicle was towed to the local dealer, who was unable to determine the cause of the failure. The manufacturer was contacted and opened a case. The failure mileage was approximately 5,781.

The contact owns a 2025 Jeep Cherokee. The contact stated that occasionally while driving at slow speeds, the transmission slipped into park(P), causing the vehicle to jerk to an unintended stop. There was no warning light illuminated. The vehicle was taken to a local dealer where it was diagnosed, and the contact was advised that the failure could not be duplicated. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 3,000.

My 2025 Jeep Grand Cherokee 4xe began with an intense burning smell followed by the “Service Hybrid Electric Vehicle” warning light illuminating. After this, the vehicle experienced numerous electrical issues with the infotainment system, and the air conditioning failed. At one point, both the service and battery lights came on and the car lost all power, would not shift from park, and could not move. The service light continued to illuminate a total of eight times. During the seventh and eighth occurrences, the vehicle became unsafe: once while stopped, the electric and motor systems appeared to fight for power, and the next time while traveling around 55 mph, the car suddenly lost power and rapidly decelerated, creating a serious risk of a rear-end collision. This problem has been reproduced by the dealership, who attempted to replace the Module Control Module without success. Dealership and myself contacted the manufacturer and were told there is currently no fix and to “hang tight” until one is available. Due to the severity and ongoing nature of the issue, I have also filed a claim with NCDS USA for further support.

When driving the vehicle the check engine light would flash adn the car would start shaking, we took it to the dealer and they said they did a update it was all set, on the way home we had the same issue execpt worse so we had it towed to the dealer and they installed a ignition coil, we picked it up and the same issue. We're now told it needs major engine work and there waiting on parts but we can drive the car until the parts come in because the dealer does not have a loaner but the vehicle is not safe to drive, Chrysler refused to take the car back and refused to do a buy back. The dealer does not respond and chrysler has not been any help.
