Engine And Engine Cooling Problems of Jeep Grand Cherokee - part 1

While driving in active traffic at approximately 6 pm, our 2023 Jeep Grand Cherokee 4xe experienced a catastrophic, sudden loss of propulsion/driving power with no prior warning. The vehicle would not switch to gas, completely died, and refused to restart even in e-save mode. A dashboard warning appeared: 'plug in vehicle for battery conditioning. ' we were stranded in an active lane of travel and nearly rear-ended before securing police assistance (911 call) and a aaa tow. This directly mirrors known safety risks regarding sudden loss of power (recall 78c / NHTSA 25v766) and high-voltage battery failure.

1). While driving the message shows vehicle is not in park. Then the motor shuts off (at any speed). This happened several times (I was on my way to take my wife to chemo infusions)! this is very dangerous when driving and caused almost an accident on the highway!!! 2), when turning the motor on, the seat moves into the pre-set drivers position, then moves back again and then the motor shots off. The car can't be driven then for a few minutes.

On four separate occasions on 10/13/26, the 2024 Jeep grand wagoneeer experienced sudden and complete vehicle systems shutdowns while being driven. Vehicle owner and two daughters were in the car. It was early morning (5:15am), and very dark. These incidents were not ordinary engine stalls. Suddenly and without warning the vehicle's engine shut down, all electrical power ceased, the dashboard, headlights, running lights and instrument displays went dark, and power-steering assistance was lost each time. Three of these four incidents occurred while the vehicle was traveling at approximately 15 mph, 30 mph, and 40 - 50 mph on surface streets. The worst and most dangerous incident occurred while owner was merging onto the freeway at approximately 55 mph. Because of the previous shutdowns, she had deliberately reduced speed and was traveling in the slow lane out of concern that the vehicle might fail again. Despite these precautions, the vehicle suddenly and completely shut down once more. In each of the four incidents, the owner was eventually able to restart the engine, but only after several attempts. The sudden and simultaneous loss of engine power, electrical systems, lights, instrumentation, and power-steering assistance while the vehicle was moving in the dark in traffic created an immediate and substantial risk of a serious or fatal collision. Following the fourth incident, the vehicle was towed to a Chrysler/Jeep dealer for investigation.

I am writing to formally request a review of an unresolved safety recall on my 2023 Jeep Grand Cherokee. I recently received a notice regarding safety recall 89d/NHTSA 26v-562, which indicates a serious rear coil spring hazard. Currently, replacement parts are unavailable, still being developed and no remedy has been provided. Because this defect poses a severe safety concern, I cannot safely drive the vehicle. Being left without safe transportation-through no fault of my own-creates an extreme hardship. Under federal standards and manufacturer responsibility, owners should not be stranded or forced to drive unsafe vehicles waiting indefinitely for backordered parts that have been unsuccessfully developed two times already. I am requesting that Jeep corporate authorize a free loaner vehicle or full vehicle buy back at my local dealership; [xxx]. Please contact me promptly at [xxx] with a case reference number and details on how my alternate transportation will be covered. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Jeep just died going down the road - idle is off - report from computer says misfire on cylinders and bad emissions. Also auto shot off doesn’t work and radio freezes up.

As I drove on the interstate, a warning came up saying that my vehicle speed may be limited. Almost immediately after the engine shut off completely and the gearbox locked. The dash said to press the brake and the on/off button, but when I tried it wouldn't work and a notice came up on the screen that I couldn't do that because I wasn't in park. My engine would not turn back on, and I had to coast to the side of the rode.

The contact owns a 2007 Jeep Grand Cherokee. The contact stated that while driving at approximately 40 mph and exiting an expressway, the vehicle stalled while the brake pedal was depressed to decelerate. The contact shifted into neutral (n), and the engine was restarted to resume driving. Less than 5 miles later, the failure recurred while making a right turn. The vehicle was taken to an independent mechanic, who diagnosed a failed throttle body and replaced the component. Following the repair, the failure persisted and increased in frequency, occurring while decelerating or coming to a complete stop. The dealer was contacted and confirmed that the VIN was not included in a recall. The failure mileage was 124,981.

[incident description & system failure] on October 4, 2026, at approximately 30,340 miles, hybrid propulsion and charging system completely failed while the vehicle was in motion. The vehicle suffered a sudden "loss of motive power" and stalled completely on a public road. The vehicle was towed immediately and is currently inspection upon request. [safety risks experienced] the vehicle suffered a catastrophic power failure and stalled suddenly in the middle of a public road. This created an immediate hazard for a severe rear-end collision. Furthermore, according to the manufacturer's official safety recall 68c (NHTSA 25v-741), this specific battery pack poses an unmitigated vehicle fire risk, threatened by both traffic hazards and potential thermal runaway. [dealer confirmation & inspection status] the defect has been officially reproduced, confirmed, and documented by an authorized dealer. Following the sudden stall, the vehicle was towed to mcpeeks cdjr of anaheim on October 5, 2026 (repair order #158337). The service advisor and technicians confirmed the failure, noting the active check engine light and red battery light. The vehicle is currently under inspection and storage at the dealership, as the manufacturer's technicians have been unable to remedy this recurring. [prior warning lamps, messages & symptoms] at the same time the engine stalled on October 4, 2026, the dashboard illuminated a red battery warning light and a check engine light, by a system message: "service charging system. The vehicle had a long history of chronic hybrid system symptoms and was previously brought to the dealer for multiple official safety recalls regarding the high-voltage battery (95b in Dec 2024, 73c in oct 2025, and 68c in Jan 2026). The manufacturer issued a warranty extension letter (program xu1) for this defective battery pack. Despite all prior software flashes and recall "remedies" performed by the dealer, the system completely failed, proving the defect is incurable.

Vehicle experienced a sudden loss of motive power at highway speeds without warning. The vehicle lost total propulsion at 60mph with zero dashboard error text or warning lights. Driver pressed fully on gas pedal to avoid activating the regenerative braking system. Driver pumped gas pedal but no response from vehicle. Vehicle began to lose speed while operating on an interstate freeway in the dark (between 6a - 7a). Driver began shifting into neutral and back to drive which only restored power for one second before cutting out again. There are no text errors or engine indicating warnings or alerts. Vehicle stalled and driver put on hazards and slowly made way to the shoulder and nearest exit ramp which was ~2 mile from event start to exit ramp. Event happened September 18, 2026. Another identical event on the same stretch of interstate reoccurred on October 2, 2026 which prompted owner to take to the dealership for diagnostic. Jeep dealership was unable to diagnose or duplicate the issue.

My Jeep diesel had the software update for the crankshaft sensor tone ring, but the tone ring failed, and my car is stuck in limp mode. Is the replacement of the tone ring covered under the original recall,or do I have to pay for the repair?.

My 2026 Jeep Grand Cherokee has experienced repeated engine shutdown and braking-related failures while driving. The vehicle is currently at an authorized Jeep dealership and is available for inspection upon request. On may 17, 2026, while driving to fair oaks dealership due to an unusual engine noise, the check engine and brake warning lights came on. The engine then shut off while I was in the roadway, and I experienced loss of normal braking ability. I was frightened but managed to move the vehicle safely to the side of the road without a collision. The dealer inspected the vehicle, replaced the spark plugs, and returned it on may 29. I later received a recall notice involving the spark plug issue. I returned the vehicle to the dealer on September 11, 2026, and the recall/service work was completed. On September 23, 2026, while driving to work, a similar dangerous failure occurred again. The check engine light came on, the engine shut off while the vehicle was moving, and I again experienced a braking problem. I was terrified but fortunately managed to stop safely. The vehicle was towed to the authorized Jeep dealership. The dealer inspected it and told me the problem was related to the auxiliary battery and repaired it. The problem has therefore occurred more than once and has been inspected/repaired by an authorized Jeep dealer. Jeep customer care has also been notified under case #98217351. To my knowledge, police and insurance representatives have not inspected the vehicle because no collision occurred. I have not picked up the vehicle because I no longer feel safe driving it. An engine shutting off together with braking problems while the vehicle is moving creates a serious risk of a crash, injury, or death to me, my family, other motorists, and pedestrians. No one has been injured so far, but I believe we were extremely fortunate. I request that NHTSA investigate this repeated safety failure.

"I am filing this supplemental report to provide critical new technical information regarding a 2026 Jeep Grand Cherokee limited reserve. This vehicle has experienced recurring engine instability, including rough idling, jerking, bucking, and loss of power. Most critically, on September 22, 2026, the vehicle nearly stalled while traveling 25–30 mph through a busy intersection, creating an immediate and severe safety hazard. Following this incident, an extensive investigation by douglas Jeep, stellantis star technical assistance, and a manufacturer engineer revealed oil contamination inside the engine cylinders and on the spark plugs. This is a recurring issue; the spark plugs were replaced prior to the vehicle's delivery in August 2026 and were replaced again in October 2026. Despite the involvement of a stellantis engineer, the manufacturer has failed to provide a diagnosis of the root cause of the oil contamination or a permanent repair. The vehicle has spent approximately 30 cumulative days out of service since August 17, 2026. I am reporting this as a systemic mechanical failure that poses a significant risk of sudden power loss during operation. ".

On September 22, 2026, at 1,445 miles, my brand-new 2026 Jeep Grand Cherokee suffered a sudden powertrain failure and almost stalled in a live traffic intersection. The vehicle experienced an active loss of motive power with no dashboard warning lights. I drove it immediately to douglas Jeep, where the service manager scanned the vehicle and found active fault code p032f-00 (insufficient engine torque) stored in the computer. The vehicle was grounded the next morning, September 23, 2026. Authorized technicians confirmed liquid engine oil intrusion into the cylinder head had flooded the main chamber spark plugs. This manufacturing defect causes sudden engine hesitation and loss of motive power in active traffic, creating an imminent crash hazard. ".

I own a 2015 Jeep Grand Cherokee summit 4x4 with the 3. 0l ecodiesel, with approximately 113,170 miles. The vehicle has experienced multiple intermittent episodes of “service electronic throttle control. ” during the most recent episode, the vehicle briefly jerked/lurched forward and then experienced a significant loss of engine power/boost. I scanned the vehicle and found dtc p0336 (crankshaft position sensor a performance, intermittent). Clearing the code temporarily restored normal operation, but the fault later returned. During the most recent recurrence, the engine also cranked noticeably longer than normal before starting. Fca previously issued safety recall w79 concerning loss of crankshaft-position signal on these vehicles. The recall involved a software update intended to maintain engine operation using the camshaft signal if the crankshaft signal is lost. Fca also lists warranty extension x95 concerning the 3. 0l diesel crankshaft tone wheel. Fca technical documentation identifies p0336 as a possible symptom associated with crankshaft tone-wheel magnetic material failure. The vehicle has not yet been inspected by a dealer or independent shop to confirm the physical cause. I have stopped driving it because I am concerned that an intermittent crankshaft-position problem could result in unexpected loss of motive power, engine stalling, or inability to restart. I contacted fca customer care regarding this issue. Fca has indicated that the applicable warranty extension has expired and has not agreed to assist with the repair. I am currently using a rental vehicle while the Jeep is out of service. I am requesting that NHTSA document and review this suspected safety issue. The physical tone wheel has not yet been confirmed as failed, but the symptoms and p0336 code appear consistent with the failure mode described in fca’s documentation.

Final NHTSA complaint vehicle information * year: 2026 * make: Jeep * model: Grand Cherokee * trim: limited reserve * engine: hurricane four-cylinder * VIN: [xxx] * current mileage: 1,199 miles * incident mileage: 1,181 miles * incident location: parking lot in [xxx] * manufacturer case number: xxx * dealerships involved: sarasota Jeep and venice Jeep complaint title bucking, jerking, rough running, unexpected forward movement, and stalling in reverse complaint description I am reporting a possible safety defect involving my 2026 Jeep Grand Cherokee limited reserve equipped with the hurricane four-cylinder engine, VIN [xxx]. The vehicle repeatedly bucks and jerks during acceleration, including at approximately 5 mph in parking lots. It also runs roughly and has demonstrated unexpected forward movement. These problems affect the vehicle’s ability to accelerate and operate smoothly and may create a safety risk near pedestrians, parked vehicles, other objects, and surrounding traffic. On xxx, at approximately 4:49 p. M. , in a parking lot in [xxx], and with the vehicle at approximately 1,181 miles, I shifted the vehicle into reverse. The Jeep shook severely and stalled. After I restarted the Jeep, it ran very roughly, continued bucking, and jumped forward unexpectedly. This created a potential risk of striking another vehicle, pedestrian, or object in the parking lot. The vehicle also continues to buck and jerk at approximately 5 mph in parking lots, creating an additional risk of unexpected movement near pedestrians, parked vehicles, and other obstacles. On xxx, at approximately 6:22 p. M. , I contacted Jeep customer care and reported that the vehicle had stalled when I shifted into reverse and that it ran very roughly after restarting. The manufacturer case number is xxx. I previously reported the bucking and jerking condition to Jeep dealerships. A service advisor at sarasota Jeep stated information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The engine lag before the turbo kicks in has on two incidents now almost created 2 accidents. We have only owned this vehicle for one month. Out of that month 2-weeks of that it was in the dealership. 1- trying to merge into a roundabout 2- trying to cross an intersection my wife refuses to drive the vehicle now because it's unsafe. The vehicle has been taken to the dealer for the problem. They had it for 2-weeks and told us there is nothing wrong that's how it's supposed to run. There are no warning lights on the dash.

My 2023 Jeep grand wagoneer, VIN [xxx], has had repeated electrical, battery, power-loss, recall, and passenger-seat safety concerns. The vehicle was serviced for ongoing battery/electrical issues and remained at south hills Dodge for approximately one month. During that time, I was told no loaner vehicles were available, leaving me without transportation. When the vehicle was returned on xxx, the front passenger seat was no longer operable, although it worked properly before service. I returned the vehicle the same day and was told the part would be ordered. I asked if the vehicle was safe to drive because the passenger seat was making unusual noises and sounded like it could fail further. I was told it was safe to drive. On xxx, the vehicle was towed back to south hills Dodge because it was losing power. I contacted the parts department to check on the passenger-seat part and was told no order was in the system. I was later told the part was only then being ordered, although I had previously been told it would be ordered after the xxx visit. On xxx, I received a voicemail stating the vehicle was ready for pickup and that the power-loss issue had been addressed. However, the passenger-seat issue was still not repaired, and I was told the vehicle would need to be returned once the part arrived. The vehicle was later returned on or about xxx, with the understanding that the passenger-seat issue had been repaired. Several weeks later, a passenger noticed the seat had not actually been fixed. I returned the vehicle again, but the dealership returned it stating they still did not have the part. Around xxx the dealership was supposed to contact me once the part arrived and provide a loaner. As of xxx, I have not heard back. The vehicle also still has unresolved recalls. I am concerned the vehicle has unresolved electrical, power-loss, recall, and passenger-seat defects that may affect safe information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2018 Jeep Grand Cherokee.

Car cut off while driving, again. Full dashboard started to flash, warnings, stated that there was no battery, no gas. I was stopped in traffic and managed to pull over and had restart the car. This is the second time that it has cut off while driving . The first time my toddler son was in the car in morning traffic and it cut off. This is an extreme safety hazard for myself, my family and others driving. The entire system failed. It was supposedly fixed before but the problem is still there.

I own a 2024 Jeep Grand Cherokee 4xe that has experienced a recurring safety issue involving unexpected deceleration and loss of acceleration while driving. The vehicle unexpectedly slows down and will not accelerate beyond approximately 60 mph, creating a potentially dangerous situation, particularly on highways when merging, passing, or keeping up with traffic. The vehicle has also displayed a “service 4wd system” warning. The dealership diagnosed diagnostic trouble code c1463, “front axle disconnect control – unexpected operation,” and recommended replacing the front axle disconnect actuator/motor. The estimated repair cost was approximately $1,054. The dealership subsequently replaced the part, but the same problem occurred again afterward. This indicates that replacing the recommended component did not resolve the underlying issue. During these incidents, the vehicle’s ability to accelerate is severely limited, and turning the vehicle off and restarting it has sometimes restored normal operation. The recurrence of this issue despite the repair raises serious concerns about the vehicle’s reliability and safety. I am concerned that this defect could cause a crash or place the driver and other motorists at risk, especially when the vehicle unexpectedly loses speed in highway traffic. I am requesting that NHTSA investigate this recurring loss-of-power and unexpected-deceleration issue in the 2024 Jeep Grand Cherokee 4xe and determine whether other vehicles are experiencing the same problem.

2026 Jeep Grand Cherokee limited - once I shut down engine, when I opened the door to exit, it started beeping at me. After a few minutes looking around to make sure I hadn't left a door open or something, I thought maybe it hadn't registered that it was in park, and shut off. I pushed the "start" button, and the dash had a message "ignition on". When I tried to put it in reverse, it moved on it's own back into park, and again displayed "ignition on". I tried putting it in drive, and the "d" just flashed at me and finally moved back to "p". I'm not sure exactly when this was displayed, but there was a message at one point that said something about the "start/stop" function, but it wasn't visible long enough for me to catch what it said. I called my son who came over and we troubleshooted (I was afraid to remove my foot from the brake due to other horror stories I've heard about, so I sat there for several minutes with my foot on the brake waiting for my son to hopefully know what to do). Once he was there, he asked me to slowly remove my foot from the brake. When I did, he could feel the Jeep trying to move forward. After some other testing/troubleshooting, he asked me to lock the door and see what happened. I did so, waiting a few minutes and turned it back on. This time it worked as expected and started. I'm driving this car all the way to texas next week, and I'm terrified (especially now that I see another recall - that's 3 since I bought the car 60 days ago) that something horrible is going to happen! I do not feel safe in this car, and I just spent alot of money on it!.

We found a huge spillage in our driveway and it had a color of yellowish brown. Took it to the dealership tech found oil and coolant were mixed together and coming out of the overflow tank. Because the oil in the coolant mixed together, it went through all the components in the engine and it is a total loss. The car does not work and it needs a new engine. Had another independent car shop. Look at the car in they agreed. We had no signs of warning of anything being wrong with the car. It ran fine. The temperature gauge remained normal and never overheated. I am reading about a class action lawsuit about this situation that happened to multiple Jeep Grand Cherokees. Since the dealership told us it's a total loss. If you wanted to fix it, it will cost us over $10,000. The mechanic told us that this is not drivable even if you try to drive the engine will 09lock up and you can get into a major accident or even cause one.

Subject: 2018 Jeep Grand Cherokee – sudden loss of power, pcm failure, electrical failures, and concern regarding recall-related symptoms I am filing this complaint because my 2018 Jeep Grand Cherokee experienced a sudden and unexpected loss of power while I was driving, and I am very concerned about the safety implications and the possible connection to the recall-related electrical problems associated with this vehicle. Before the final failure, my Jeep had been experiencing electrical and starting problems. The alternator failed, the batteries went bad, and I had already paid for multiple diagnostics and repairs. At the time, we did not understand that these problems could potentially be leading to or connected with a pcm failure. I have spent approximately $800 on diagnostics and parts trying to determine and repair the cause of these issues. The most serious incident occurred when I was driving near a school and approaching a stop sign. The Jeep suddenly began losing power and would no longer operate normally. I did not receive an adequate warning that the vehicle was about to completely shut off. The dashboard/screen began flashing, electrical functions began going out, and the vehicle progressively lost power. I was able to slowly move the Jeep toward the right side of the road before it completely shut off. The Jeep then would not start again. This was extremely frightening because the vehicle lost power while I was operating it in an area where there were other vehicles and children nearby. I was concerned about my ability to safely get the vehicle off the roadway and about what could have happened if the Jeep had completely lost power in moving traffic or at a higher speed. The vehicle has since been diagnosed as having a pcm failure. I have already paid for diagnostics rather than simply bringing the vehicle in without any prior information about the problem. Despite this, the Jeep dealershiphas my vehicle now to determine if this is part of recall.

The Jeep was giving me a warning sign. It said stop slowly. Your Jeep will shut off so I replaced the two batteries. As my mechanic told me I replaced the alternator. I also replaced the ground wires. Nothing is making my Jeep start. We ran the codes on the Jeep and it came back as a u0100 code with the pcm system. No connection error. We looked up the recall information and a recall popped up for this 2018 Jeep Grand Cherokee. I am being told that I am not affected by this recall. . The Jeep was giving warning saenz before I replaced the battery and alternator. After that. It did not give warning saenz anymore. It’s just completely shut off with no warning. Leaving me on the side of the road stranded twice. It will not start and it is reading these codes.

Recall 20v-475 / 23v-411 software patch was performed, but the underlying magnetic tone wheel defect has now physically failed, causing an active crankshaft position sensor error and stall hazard. While traveling 60mph the car stalled and went into limp mode with no prior warning. The vehicle has been diagnosed at a repair shop as a fault with the crankshaft position sensor performance which was apart of a pervious recall listed above. The vehicle has not been inspected by any others at this time as its not safe to drive and do not want out of pocket cost to do so.

I purchased a new 2026 Jeep Grand Cherokee summit equipped with the new 2. 0l hurricane 4 turbo. The vehicle has a repeatable and potentially dangerous accelerator-response problem. From a complete stop, I can apply substantial/full accelerator input and the vehicle initially provides little or no expected acceleration. The vehicle may begin creeping forward and the tachometer may begin moving, but there is little corresponding engine sound or vehicle acceleration. After approximately two seconds, the vehicle begins responding and accelerating however it is still extremely sluggish and dangerous. The condition has been repeatedly reproduced in both normal and sport modes. I have also experienced delayed rpm increase and delayed transmission response/downshift while already moving. The condition has occurred when attempting to enter traffic and creates a safety concern because the vehicle does not immediately respond as expected to accelerator input. The dealership initially told me the vehicle was operating normally based on diagnostic readings amd that because of the computers and software there is no direct throttle response on these drive by wire vehicles anymore. That is simply intrue. The dealership subsequently had the shop foreman test drive with me in the vehicle. The foreman experienced the condition and agreed there was an issue with the lack of throttle response. I repeated the issue multiple times from stop, ehile turning, and at speed. The dealership is now involving a technical advisor. The dealer has told me that a stellantis service bulletin concerning similar drivability symptoms does not apply to my VIN. I am not alleging that the bulletin applies to my vehicle. I am reporting the actual safety-related behavior because I believe it warrants investigation regardless of whether my VIN is currently included in that service action.
