2025 Jeep Grand Cherokee transmission problems

Filed Nov 9, 2026 · Electrical, Engine · WV

I am filing a formal safety defect complaint regarding an acute, uncommanded deceleration event caused by an unintended Auto Start-Stop system engagement and electrical failure at highway speeds in my 2025 Jeep Cherokee (~22,000 miles). Incident Description: On XXX, while traveling westbound on [XXX] toward [XXX], at approximately 75 mph in normal highway traffic, the vehicle's Auto Start-Stop feature engaged unexpectedly and automatically while in motion. Simultaneously, the instrument cluster flashed and experienced a partial blackout, failing to display the vehicle's speed (MPH) and engine RPMs. This malfunction triggered immediate, uncommanded engine braking / rapid deceleration, dropping the vehicle's speed from 75 mph down to approximately 40 mph within seconds, without any brake pedal application. Risk Assessment & Recovery: After several seconds, the instrument cluster rebooted to normal operation, throttle response returned, and the cluster indicated that the Auto Start-Stop feature was active. I immediately deactivated the system manually via the center dash control to prevent recurrence. While light traffic on [XXX] prevented a rear-end collision, this sudden, uncommanded 35-mph drop in speed presents a severe hazard of high-speed rear-end impact, loss of vehicle control, and chain-reaction collisions on congested freeways (such as nearbY XXX). Current Status: •The vehicle was delivered to Greenbrier Motor Company in [XXX], and checked in with Service Advisor [XXX]. •The dealership has taken custody of the vehicle for electrical/diagnostic evaluation and provided a loaner vehicle. •A corporate inquiry has also been initiated with Stellantis / Jeep Customer Care. This submission is made to ensure federal records document this hazardous powertrain/electrical failure mode for potential defect trend analysis.

The vehicle experiences severe drivetrain binding, mechanical clunking, and erratic 4WD electronic timing failure while operating at normal driving speeds. During acceleration (27–28 mph, transitioning from D4 to D5 gear), the automatic 4WD transfer case / front axle disengages abruptly under load, causing an audible mechanical clunk and drive-line shock. During deceleration (31 mph down to 15 mph, downshifting from D6 to D4 gear), the 4WD system forces a re-engagement of the front axle, creating a heavy binding shock and severe mechanical clunk. This uncommanded electronic engagement and disengagement failure creates vehicle hesitation, drivetrain binding, and a potential loss-of-control hazard while driving. The issue is available for inspection and has been documented on video.

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 (the federal safety agency 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 the federal safety agency 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
