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

After the 68c recall software update upon getting my Jeep back I can no longer drive in the electric mode without the Jeep surging into and out of the gas mode at slow speeds or fast speeds. My Jeep does hesitate or bogs down prior to engaging the gas mode.

06/13/2026: third episode of 2024 Jeep gc summit (top of line) battery being completely dead after 3-4 days of no driving. I bought my Jeep in 12/2025!? another issue that others report is the difficulty of 'jumping' the battery/engine to give a start. We tried multiple times on the evening of 06/13 to no avail. On Sunday, 06/14, we revved the jumper engine to . . . . 7000 or 8000 rpms (on the tachometer) before getting enough power to successfully jump the Jeep. This new vehicle "dead electric" is very scary on how it could strand us!!.

I was at a stoplight, waiting to making a u-turn. The light turned green release the brake and went to hit the gas. The entire vehicle shut off. I lost all power and had to restart the vehicle in the middle of the intersection with vehicles behind me. It took at least 30 seconds and I ended up having to wait a cycle on the light because I couldn’t go at the time. Once I got the car back on, I lost power steering and my check engine light came on. I was able to make it to parking lot. Once I got there, I parked in the parking space the vehicle did the automatic shut off to conserve energy once I parked I press the button to shut that feature off when I did it the vehicle shut off again. I lost power to everything and had to restart the engine. This has happened multiple times as I believe it’s related to the electrical system and the automatic shut off. I’ve also had multiple other issues with the vehicle in the electrical system. The most recent being that pulling out of a parking lot onto the highway my vehicle would not shift gears, and I had to pull over to the side of the road as I could not get out of first gear. It ended up being the electrical components of the transmission. At the time of the incident listed above, I had just picked up the vehicle from having this issue replaced and had it for less than six hours when this other issue happened. We bought this vehicle used with roughly 58,000 on March 17, 2026, I’ve owned it for just over two months and in those two months it’s been in the shop more than we’ve been able to drive it due to a series of electrical incidents that causes the check engine light to go on or the vehicle to shut off.

On 5/72026@app 3:14pm after picking up one grandchild, and at a stop light on the way to p/u the other, the Jeep without warning just disengaged when the gas pedal was depressed, but to no avail. While frozen, the dashboard may have displayed something that was not noted in the panic to get the car moving! the internal panel was still illuminated, however the car would not move forwards although still in "drive" with nothing having been switched, shifted or toggled except engagement of the brake to stop at the traffic light. The Jeep had to be placed in "park", the starter button pressed, then pressed again to completely restart the vehicle. This was a potentially huge safety issue with many cars around us honking & rushing to pick up their own children, yet fortunately no one ran into us with our precious little rider!.

I am submitting this complaint regarding a serious safety-related failure involving my 2022 Jeep Grand Cherokee 4xe. I purchased the vehicle used with approximately 15,000 miles and was informed the previous owners leased it and rarely used it. At approximately 40,000 miles, despite completing all recalls in a timely manner, the vehicle experienced the exact type of hybrid system failure a recall was intended to prevent. The issue began when the hybrid system failed and left the vehicle unsafe to operate. Upon startup, only accessory power activated and the engine would not start. A full power cycle was required before the vehicle started. Immediately afterward, warnings appeared including "service hybrid system," "service charging system," "eab unavailable," "lane keep assist unavailable," "pedestrian braking unavailable," and "adaptive cruise control unavailable. " the check engine light illuminated and all hybrid modes became unavailable. Shifting became erratic and harsh. Downshifts from 2nd to 1st felt like sudden braking and caused me to hit my head on the steering wheel. During acceleration, the transmission slipped and shifted unpredictably. Fuel economy dropped from approximately 22 mpg in e-save mode to approximately 10 mpg at highway speeds. Diagnostic code p1e1d was retrieved and I was advised the vehicle was unsafe to drive. While driving to the dealership, the vehicle shut down twice while in motion. During both shutdowns, power steering and braking assistance were lost, posing an extreme risk to myself and others while moving the vehicle off a busy three-lane roadway. Dealership diagnostics determined one or both high-voltage battery systems failed and required replacement. Despite completed recalls, the issue still occurred. Parts were backordered over a month. I believe this failure and recall effectiveness warrant investigation due to the serious safety risks created by loss of propulsion, steering, and braking assistance while driving.

I recently purchased a 2018 Jeep Grand Cherokee and began experiencing serious issues almost immediately after taking possession of the vehicle. The vehicle has stalled unexpectedly while driving on multiple occasions, including during active driving conditions. It also has difficulty starting and has shut off without warning. The vehicle has already undergone multiple repairs within a short period of time, including work related to the radiator, spark plugs, and ignition coil. Despite these repairs, the issues continue. This creates a significant safety concern, as the vehicle becomes inoperable without warning, especially during daily highway driving. I rely on this vehicle for transportation, and it is currently unreliable and unsafe to operate.

My vehicle some times gives a jerk once in awhile I also have been told I cant charge my vehicle these recalls have no fix to them I am getting really tired of this and want Jeep to buy back my vehicle!!!.

I, [xxx] was driving home from work on Friday, may 1st on [xxx] in [xxx] during heavy traffic when my vehicle suddenly shut off while traveling approximately 65–70 mph. I initially thought I may not have been pressing the accelerator hard enough, but the vehicle would not respond at all. I then looked at the dashboard and saw a message that said “push brake to start. ” at that moment I realized the vehicle had shut down completely while I was in active traffic. I had to coast across three lanes of traffic without any propulsion to reach the shoulder. During this time, I was nearly struck twice from behind because I could not maintain speed with surrounding traffic. Once I reached the shoulder, I was able to restart the vehicle. I was extremely shaken and frightened by the incident. I do not feel safe driving this vehicle again. I was very aware that I could have been seriously injured or killed, and I am thankful I was not struck. I am especially concerned about what could have happened if my grandchild had been in the vehicle with me. This incident occurred after a recall repair had already been performed in September 2025 related to powertrain/hybrid system issues. The failure appears to be the same or similar to the condition the recall was intended to correct. After restarting the vehicle, I drove cautiously to my husband’s workplace and left the vehicle parked. Since the incident, I have experienced ongoing anxiety and distress reliving what happened. This vehicle was intended to be a long-term purchase, and it is extremely concerning that it now appears unsafe to operate. This event represents a serious safety hazard. A sudden loss of propulsion at highway speeds without warning creates a high risk of crash, injury, or death. I am requesting that this issue be investigated, as the prior recall repair does not appear to have corrected the problem. I do not feel this vehicle is safe to operate. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The vehicle loss drive power in the middle of driving several times back to back, a red wrench and a message saying to service hybrid system warning appeared. Purchased used in September 2025, had open recall fixed and later recall fixed after in early 2026.

See attached document for complaint.

My vehicle is a subject of recall 22v-406 (fca recall number z46 [xxx] ), and the repair work for that recall was completed on April 26 of 2024. On April 23, 2026, the vehicle failed in the exact way described in the recall: loss of power, particulate in the fuel lines, failed high-pressure fuel pump. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was sold a defective 2024 Jeep Grand Cherokee 4xe. Both the batter and engine can catch fire while parked and is not recommended to be parked near other cars or any structures. The dealership told me that the recalls were not on my vehicle at the time of purchase per stellantis (November 7, 2025) which in fact they were. They said my car was not protected under lemon law which it is. And a number of other misinformation. I bought the car for around $35,000 and in 6 months the value depreciated to $20,000 per the sales manager michael morris. They claimed to have no access to this purchase in their database.

First, after a trip of approximately 100 miles, the vehicle would not advance after stopping at a stop sign. I had to shift from drive to park and back to drive before the vehicle would move. In the second case, again after a trip over 100 miles, primarily on the highway, the vehicle failed to shift out of first gear while the engine revved to over 7,000 rpm when I left an intersection. In that instance a warning light came up on the dash indicating rpms in the red zone. Once again I had to pull over, put the vehicle in park and re-engage drive before the vehicle would drive in a more normal fashion. It was the following day, when I entered the dealership for a service appointment, that the check engine light illuminated and the vehicle did not run smoothly. The service department determined it was a spark plug issue and claims the problem has been resolved. They also said this issue is fairly common on new (2026) Jeep Grand Cherokee models. There is less than 1,200 miles on the vehicle. I feel I was very lucky that the situation in both instances was relatively safe and there was minimal risk of injury, death and/or property damage. I have lost all confidence in the vehicle.

The thermostat failed causing the vehicle to go into a reduced power mode while climbing a hill with a trailer. The dealer has a technical service bulletin for this issue but the overheating can call engine damage or an accident when the vehicle has reduced power. There were no warnings on the cluster until the car was already in a protection mode and power had been reduced. The cluster coolant temperature gauge is slow to respond and not accurate.

I am writing to formally report a serious safety issue with my brand-new Jeep Grand Cherokee (got it from darcars rockville, MD dealership) and to request immediate resolution under warranty and applicable consumer protection laws. I purchased this vehicle with the expectation of reliability, safety, and comfort for my family. Unfortunately, within a very short period of ownership, the vehicle has experienced repeated and dangerous failures. On 17th April 2026, while traveling at approximately 65 mph on a highway in pennsylvania around 1:00 am, the vehicle suddenly shut down without warning. This created an extremely hazardous situation for my family. We contacted roadside assistance, but no help arrived until approximately 8:00 am. Due to freezing temperatures and lack of heat in the vehicle, we were forced to call 911 for assistance and were transported to a nearby hotel around 3:30 am. The vehicle was subsequently towed to a dealership, where diagnostics were performed. We were informed that the issue was related to a coding or malfunction and that it had been resolved. However, just two days later, while returning home, the exact same issue occurred again under similar conditions—vehicle shutdown at highway speed. Once again, we were stranded at night, forced to rely on emergency services, and did not reach home until approximately 4:30 am. This pattern of failure is unacceptable and represents a severe safety defect. My family’s safety was put at significant risk on two separate occasions. As a result, we have completely lost confidence in the vehicle’s reliability and safety. Immediate escalation of this case and a full technical investigation a written explanation of the root cause of these failures a permanent resolution to ensure this issue cannot recur consideration of a manufacturer buyback or replacement under applicable lemon law provisions.

One day after driving the vehicle around town and after we parked it in the garage, we noticed a large pool of oil on the garage floor. After taking it to a service station, for inspection, we were told that the oil leak was caused by a cracked plastic oil cooler. We were told if we had not noticed the oil leak, the engine could have locked up and caused a serious accident. The next day we were going to take the vehicle on the highway for a trip. The service station said they have had multiple cracked plastic oil coolers come in for repairs on the same vehicle, year, make and model. There was no warning.

I am a former transmission calibration engineer at stellantis, so I know what I'm talking about. I experienced an engine stall event while coasting down in speed. I was in town, driving about 30 mph, and coasting (0% pedal). I lightly applied the brakes and while the vehicle was still in motion (coasting) the engine stalled. The information cluster displayed a message that said "put the vehicle in park and restart the engine. " I coasted around a corner, came to a stop, put the transmission in park, and restarted the engine. No mil or codes were set. I have a scan tool and confirmed later that no codes were set. I'm fairly certain the engine was in dfso (decel fuel shutoff) when the issue occurred as the conditions were all correct for dfso (engine was in normal operating temperature range, gear was 5th or 6th when coasting was initiated, and pedal was 0% for several seconds before the issue occurred). Loss of propulsion is an obvious safety concern as I lost control of the vehicle.

My 2017 Jeep Grand Cherokee just completely lost power again and almost got hit by the car following me. Almost got hit again coasting to the side of the road! this has happened before and the repair shop tried updating software which did not fix it. Why was the 2017 not included in your recall of the power transfer case? repair shop diagnosed problem the last time it happened as the ptc! I am an attorney and want this included in your 2019-2023 recall! please do not force me to file a lawsuit to fix this safety issue!.

Sudden unintended acceleration while braking. Engine revved against brake input. Has happened multiple times. Need to step on the brake hard and wait for it to pass.

Nhtsa complaint draft I am filing a follow-up complaint regarding recall 78c on my 2024 Jeep Grand Cherokee 4xe. This recall involves risk of catastrophic engine failure, loss of propulsion, and potential fire. It has now been approximately 5 months since the recall was issued, and there is still no remedy available. I have completed all other recalls that had remedies and have fully complied with all manufacturer instructions. Due to the safety concerns and lack of a remedy, I was instructed by stellantis to obtain a rental vehicle when a loaner was not provided. I incurred out-of-pocket rental expenses based on this guidance. However, despite multiple follow-up emails, stellantis has failed to provide any reimbursement process, timeline, or response regarding these expenses. Additionally, I have received conflicting and unclear guidance regarding safe operation of the vehicle, including whether it can be driven or charged. This has significantly impacted my ability to safely use the vehicle for its intended purpose. At this point, I have made multiple documented attempts to resolve this directly with stellantis and have received no response. This situation reflects a lack of remedy, lack of communication, and failure to reimburse expenses incurred under manufacturer direction. Immediate action and oversight are needed.

The rear parking collision warning abruptly stopped working. The engine smells like it’s burning. The recall 68c has no remedy currently. My neighborhood is at risk due to this outstanding issue.

This submission is an update to NHTSA complaint #11727024. The vehicle continues to experience recurring engine overheating and misfire conditions. These issues have been previously diagnosed and are consistent with known manufacturer technical service bulletins (tsbs) related to this engine. Despite this: the dealership has not performed the appropriate diagnostic protocol (including star testing) the manufacturer, stellantis, closed my case without resolving the issue no repair or corrective action has been completed the vehicle remains in operation due to lack of manufacturer support. This condition presents a potential safety risk, including: loss of power while driving risk of engine failure or shutdown increased risk during normal roadway operation the vehicle is regularly operated by my 17-year-old daughter, which increases concern regarding driver safety and reliability of the vehicle under these conditions. This situation reflects: a known defect documented by the manufacturer failure of the dealer network to properly diagnose/repair closure of a manufacturer case without resolution of a safety-related issue I am requesting that this complaint be reviewed as part of any broader pattern of similar failures and considered for further investigation.

Had a recall done in February and 3 weeks later the car would not start randomly no warning lights illuminated on the dash prior to being shut off and once it would start it threw 3 codes for p0850, u0100, and u1267 all related to the parts replaced in February for the recall for the 2nd time now regarding the same parts. And trying to get a reinspection done for the recall bc the parts seem to have failed and its been a living nightmare. And unsure why no warning lights were illuminated prior to the car not starting randomly.

While attempting to park my vehicle, it suddenly accelerated on its own, causing the car to move quickly toward a tree and a nearby building. I immediately attempted to stop the vehicle by pressing the brake pedal, but the car continued to accelerate. The engine was roaring, and I even tried using both feet on the brake pedal in an effort to stop the vehicle, but it did not respond. The only way I was able to stop the vehicle was by turning off the engine. Due to the unexpected acceleration and my concern that it could happen again, the vehicle was not safe to drive. A tow truck was called, and the vehicle was transported to a mechanic for inspection.

I was stopped at a red light and when it turned green and I proceeded to drive, my car started to hesitate and quit moving right in the middle of the road. I finally got it to the side of the road. When I attempted to reverse it hesitated again and the r symbol started flashing and the engine light came on. The engine codes are p1d97 clutch a or d defective and p1db8 unintended torque applied while in neutral. Now it's not even drivable.

The contact owned a 2018 Jeep Grand Cherokee. The contact stated that while unloading groceries out of her vehicle with the vehicle in park(p) and the engine on, grayish-white smoke began to emit from the vehicle without warning. The contact turned off the vehicle and checked under the hood, where she saw flames in the engine. The contact then ran to the fire department, which was nearby, and informed them of the fire. The fire department arrived at the scene with a fire truck and extinguished the fire. The police department also arrived at the scene, and a police report was filed. No injuries were reported due to the fire. The vehicle was destroyed as a result of the fire, but was not towed. The dealer or manufacturer had yet to be notified of the failure. The vehicle was not repaired. The failure mileage was approximately 74,000.

Driving on highway, "service hybrid electric vehicle system" warning came on, vehicle lost all propulsion, needed to pull over on road and restart the engine. Almost got into accident with car behind me because of sudden power loss.

Unknown what actually occurs but the entire car shuts off while driving. It has happened to me twice in traffic. Once no warnings, the second time the tire pressure sensor fault flashed went away and then the entire car just shut down while I was driving. I had my child with me and was a scary moment could’ve cause a serious accident or potential death. Car was stuck in the road for over 30min before I could get it to restart and move to a safer location.

The engine power cuts of randomly while driving with no warning at all. When it happens the steering locks up veering the vehicle to the left so you have no control and at the same time the power brakes lock up and you are unable to stop the vehicle. Everything else works when this happens lights, radio, heater, air conditioning. No warning lights display. I had the vehicle with a mechanic that kept it for over 4 months to test drive and see if it would occur. It happened while he drove it but no codes show up to determine the cause. I had it towed back to my home and contacted Jeep Chrysler and they gave me a claim number to bring to my local Jeep dealer. They had it for over a week and unfortunately the Jeep ran fine so once again no resolution to be able to fix. I bought the Jeep from carvana 9/7/24 and am still paying it off but yet haven't been able to drive it for the past 15 months because it is unsafe for myself and anyone else on the roadway.
