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

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.

I have purchased brand new a 2026 Jeep Grand Cherokee the engine is the new 4 cylinder hurricane engine with turbo I have had multiple incidents of flat to dull pick up when in motion between the speeds of 15-30 mph resulting in multiple near misses for serious accidents. I submitted a ticket with Jeep, had the vehicle reviewed by my dealer only to be told this is within normal limits two days ago my vehicle went into full rattle mode and shut down on me in an intersection causing another near miss. My Jeep is in the shop again as of this writing I also have had multiple shutdowns of my electronic screens when the vehicle is under load.

This engine does not run smoothly, it jerks coming out of a stop so there is delayed acceleration and it jerks every time you change gears. So I am almost rear ended at every stop light and stop sign. It also can lose acceleration or fail to accelerate on highways.

Vehicle was unable to be shutdown and was locked in park. Can was not responding to turning off while in the garage and engine running. Since the vehicle was inside an attached garage, we were concerned about carbon monoxide getting into the house. No way to turn car off and had to involve police/fire department. Disconnected the battery terminal in the trunk which was unable to be opened, so we had to crawl through the side passenger door to get into the trunk. The vehicle is now at the dealer (wilde Chrysler Dodge Jeep ram, at [xxx] in [xxx]). No police report #, but cad entry from officer in having to assist. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

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.

?vehicle information: ?year / make / model: 2022 Jeep Grand Cherokee overland 4xe ?component(s) involved: engine / hybrid powertrain / electrical system / sudden loss of drive power ?current mileage: approximately 48,000mi ?incident summary ?I am filing this complaint because my 2022 Jeep Grand Cherokee overland 4xe has developed a dangerous new defect following an official recall service: the engine completely dies while accelerating on the highway. ?I took my Jeep to an authorized dealership to have the safety recall performed for the engine shutdown issue. Before this recall work was completed, I had never experienced the vehicle dying on the highway. Since the recall "fix," however, the engine has cut out completely 4 separate times while accelerating at high speeds. The most recent time happened today (August 3, 2026). Losing all pedal response and motive power in fast-moving traffic with no warning is terrifying and creates an extreme hazard for myself and everyone around me. ?history of vehicle issues & extended shop time ?this sudden highway stalling comes on top of severe, ongoing electrical problems that have plagued this Jeep. Altogether, the vehicle has spent months sitting in the dealership shop, yet the problems remain unfixed: ?post-recall engine shutdowns: 4 separate complete power loss incidents while accelerating on the highway (latest occurrence: August 3, 2026). ?unresolved battery drain: ongoing parasitic battery drain that kills the battery, requiring multiple rounds of diagnostics without a solution. ?pervasive electrical glitches: frequent system glitches, including frozen touchscreens, instrument cluster reboots, random dash warning lights, and connectivity drops. ?media hub issues: hardware problems involving the media hub module. ?requested action ?the recall fix did not solve the safety hazard—it seems to have triggered a new, life-threatening stalling issue on the highway, along with the string of other issues, it's unsafe to drive.

The contact owns a 2024 Jeep Grand Cherokee. The contact stated that while test driving at an undisclosed speed, an unknown warning light flashed on the instrument panel. The dealer informed the contact that the battery was low and that the light had been replaced, while also informing the contact that the vehicle had experienced difficulty starting prior to purchase. Days later, upon starting the vehicle, all warning lights illuminated and the vehicle stalled. The vehicle was towed to the dealer, but the dealer was unable to determine the cause of the failure, cleared the codes, and returned the vehicle; however, the failure recurred. While driving, the steering wheel became inoperable, causing the driver to lose steering control, and the vehicle crashed into a Ford mustang. A red steering warning light illuminated. A police report was filed. There were no reported injuries, airbag deployment, or fire. The vehicle was returned to the dealer, where it was determined that the vehicle was undrivable, could not be inspected in the service bay, required an unknown replacement part, and that the steering wheel computer failed to communicate. The manufacturer was notified of the failure and advised the contact that the vehicle did not qualify under the lemon law, prompting the contact to report the issue to the attorney general, who referred the contact to the NHTSA hotline. The failure mileage was approximately 55,000.

This is for Jeep's brand new hurricane 4 engine. The buyer has no option to chose the reliable 3. 6l 6 cylinder in the 2026 summit model. Theis 4 cylinders throttle response lag, from a stop or slow speed, is extremely dangerous! when trying to move into traffic from a street or driveway the Jeep just rolls slowly as if it was in neutral; there is no acceleration. I can floor the accelerator pedal & it takes literally a full 2 seconds every time before the engine responds. All the while the traffic you are trying to safely merge into is rapidly approaching. I took my Jeep to the Jeep service department & their response was "no dtcs. Compare to like vehicle, at this time working to spec . Note engine is turbo equip and may have a slight delay until turbo kicks in". No throttle response for 2 seconds does not fall into the category of a "slight delay". When a vehicle is approaching at 45-50+ mph and you have no throttle response . . . It's an accident waiting to happen.

Problem was oil filter housing made of plastic. It was cracked and no warning light that oil had leaked out. Car suddenly decelerated as I was merging into traffic on freeway causing vehicles coming up behind to brake rapidly including a semi truck which had been 200 yards back. I rolled onto shoulder with warning lights activated. Pure luck it was not a major accident. Had it fixed at local mechanic in area and was told it is common problem on several makes of vehicles. Mechanic replaced with aluminum one. Gave me a reduced price of $1200.

The transmission fails constantly when we are accelerating - approxx 50-58 miles per hour the transmission freezes & the rmp's stay @ 4-5 thousand for 20-30 seconds - it fails to downshift. This is extremely dangerous at any time & can cause a major accident if the vehicle is stuck & you need to stop! we have have left the car several times for this issue & they keep telling us they cannot replicate the issue. (we are older & we are given looks like we are nuts).

My car started jumping after purchssing it in November 2025 used. The gear would feel like it was slipping. In March 2026 I parked my car turned it off let off the brake and it rolled. I have used the emergency brake since then. The gas gauge is off. The miles and gauge do not line up correctly and I was advised fuel pump may be off. It will drink gas up within a few miles. Check engine light came on without warning. Took it to check it out said oil sensor. He said replace it soon as you can still driveable. The next day I drove to my sons college and the Jeep had no power, the check service on the screen popped up. And the Jeep would not accelerate. I was anle to take it to o'reilly and several codes appeared stating 2 gear shift ratio inaccurate 7 gear shift ratio inaccurate, engine oil pressure control circuit performance stuck off, clutch temp threshold achieved auto stick inhibit. The employee said he had never seen these codes populate. He asked if I had smelled any transmission fluid burning. I said no. No leaks nothing. Had the car for 7 months. He stated transmission isnt any good. That I would need a deep decoding done to say for sure. Car is in limp mode now. Unable to drive safely.

This complaint is being filed regarding a failed and botched remedy of two federal safety recalls: the crankshaft position sensor recall and safety recall z46 (high-pressure fuel pump) on my Jeep Grand Cherokee ecodiesel. The vehicle was delivered to kendall dcjr of soldotna, ak for the recall services. The technician performed the recalls, but the high-pressure fuel pump failed immediately, resulting in systemic fuel leaking directly into the engine's crankcase oil pan. The fuel contamination thinned the motor oil, dropped oil pressure, caused the oil filter to collapse, and resulted in a catastrophically blown motor. Physical inspection confirms the entire fuel system is filled with destructive metal shavings and debris ("glitter") from the disintegrating pump, requiring a complete replacement of all fuel components and the engine assembly. The vehicle has been rendered entirely undrivable and has been sitting out of service at the authorized dealer for over 30 cumulative days. The manufacturer (stellantis/Jeep) has failed to provide a safe, effective, and timely remedy for these safety recalls, and is refusing to issue a corporate rental authorization (cra) or alternative transportation while my vehicle remains grounded due to the safety defect's failure. This is a complete failure to execute a federal safety recall remedy in a reasonable timeframe.

My 2014 Jeep Grand Cherokee suffered a total intake manifold failure directly resulting from a secondary breakdown of safety recall w79 (NHTSA campaign 20v-699). Physical teardown at an independent facility exposed a 70% engine runner restriction and seized glow plugs due to volatile exhaust sulfur, creating an active fire risk. On July 9, 2026, lafontaine fenton was presented with clear mechanical photos and a continuous 2023 dealer repair loop under customer id [xxx], but formally refused to open a corporate star case or dispatch flatbed transport to remedy this active safety defect.

The contact owns a 2024 Jeep Grand Cherokee. The contact stated that while driving 35 mph and making a left turn, the vehicle decelerated to 29 mph and failed to properly accelerate. The accelerator pedal was depressed and went down to the floorboard. The vehicle was pulled over safely and avoided a crash. The contact attempted to restart the vehicle. The battery power was at 1 percent after driving the vehicle. The local dealer was contacted about the lemon law. The vehicle was towed to the local dealer, and the contact was informed about the cost of a diagnostic test. The vehicle was not diagnosed or repaired. The manufacturer was contacted and referred the contact to the dealer for assistance. The failure mileage was approximately 54,130.

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.

Component failure & inspection: the engine water pump assembly failed. This specific failure is a documented factory defect explicitly covered under manufacturer technical service bulletin (TSB) #9100212 and tracked under NHTSA id #10244344. The failed component was replaced by an authorized dealership; the physical part is not available, but full diagnostic logs and proof of failure are stored in the manufacturer database under university auto center invoice #6044139/1. Safety risks: the water pump suffered a sudden, catastrophic structural failure while operating at highway speeds—a known vulnerability detailed in TSB #9100212 and NHTSA id #10244344. This caused an immediate loss of engine coolant and a rapid spike in engine temperature. The vehicle lost power and was forced to make an emergency pull-off onto a busy highway shoulder, stranding occupants in a highly vulnerable position. A sudden cooling failure at highway speeds creates an immediate risk of engine seizure, vehicle fire, or traffic collision while disabled on the roadside. Dealer confirmation & inspection: yes. The failure was inspected, reproduced, and confirmed by an authorized manufacturer dealership (university auto center). The dealer confirmed that the water pump assembly completely failed and required replacement, perfectly mirroring the defect parameters outlined in TSB #9100212. Warning lamps & prior symptoms: there were no prior symptoms, noises, or early warning indicators. The component failed instantly without warning. The first indication was a sudden, rapid flashing of the engine temperature warning light and an "engine overheating" message on the dashboard cluster, immediately followed by a loss of power.

My son just bought the car from a private party. On our way home the engine light and a lightning bolt icon illuminated on the dash, followed by the vehicle going into limp mode. We had the vehicle scanned for codes and it came back with p0336 (crankshaft position sensor performance). After much investigation online, we found out that this is a known issue with the crankshaft position sensor and, most importantly, the tone wheel on the back of the engine. We looked up recalls on the vehicle and found a safety recall had been issued. While some vehicles affected received replacement of the tone wheel and sensor, others just received a software update. This particular vehicle received the software update. The issue is that the magnetic material on the tone wheel delaminates from the tone wheel. This is a costly repair that should have been fixed correctly from the beginning, not just a software patch. It is a safety concern because it is dangerous when you are traveling at highway speeds and it goes into limp mode.

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.

#2 cylinder misfire code p0302. A known problem with this engine. A compression test reveals a common defect with this engine.

I bought the vehicle less than 60 days when it had a major engine failure. The spark plug broke off into the engine and bounced around causing a failure. This is a known problem with this vehicle from the factory, from which I was not aware. At first they said they were putting a new engine in and now corporate is trying to get it out the door ASAP so they cant be forced to buy back the vehicle as a lemon, which I requested through corporate and started an arbitration process per the contract. The vehicle is being serviced at diehl of moon. The service manager there I am dealing with is james. They have had my vehicle since the check engine light came on and was flashing on June 17th.

Vehicle information: 2018 Jeep Grand Cherokee overland 3. 0l v6 ecodiesel 4x4component affected: fuel/propulsion system (high-pressure fuel pump) safety incident narrative: the vehicle previously underwent a mandatory manufacturer safety recall replacement for the bosch cp4 high-pressure fuel pump under fca safety recall z46 (NHTSA campaign number: 22v-406). At 111,948 miles, while operating the vehicle, the engine suffered a sudden, catastrophic mechanical failure accompanied by an immediate and total loss of engine oil pressure. This caused the engine to suddenly stall and lose all propulsion while in motion, creating an immediate and severe highway safety hazard to myself and surrounding traffic. The vehicle was towed to an authorized Jeep dealership under repair order #5823328. The manufacturer (stellantis) and the dealership are currently refusing to authorize diagnostic teardown labor or a mechanical review of the internal safety recall componentry to investigate an acute internal fuel-pump shaft seal leak or residual micro-particle metallic debris from the prior campaign. An internal drive-shaft seal failure on this replacement pump architecture dumps raw diesel fuel directly into the engine's internal oil crankcase, causing severe oil dilution, an immediate collapse of structural oil pressure, and catastrophic engine seizure. The manufacturer is attempting to shift 100% of the financial burden ($25,000 engine replacement cost) onto the consumer, actively obstructing an essential safety failure investigation into a federally recalled component.

No check engine lights prior to this, car started to make a noise pulled over to check it out as I was merging over low oil pressure showed and coolant level over temperature, gear then dropped to neutral, managed to pull over without any accidents car then shut off, oil leaked, it makes a horrible engine noise when starting, had to tow it back. Only had the car a year maintenance was up to date.

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!!.

Vehicle & purchase details: 2018 Jeep Grand Cherokee (3. 6l v6 pentastar engine). Purchased on/around April 27 in agreement with my credit union. Incident & defect description: upon taking delivery, the vehicle immediately displayed diagnostic warning codes. The selling dealer attempted diagnosis/repair for a week before directing me to take it to bonham cdjr in bonham, TX. Bonham cdjr cleared the codes and returned the vehicle. A couple of weeks later, while my wife was driving home, the engine suddenly and severely overheated without warning. I instructed her to pull over immediately to prevent engine destruction or stall in active traffic. My wife was stranded on the roadside in extreme texas heat until a flatbed wrecker towed the vehicle back to bonham cdjr. Warranty obstruction & known failure point: upon arrival at bonham cdjr, I informed service advisors that my third-party warranty provider (first guard) would handle coverage. However, the dealership demanded a $1,300 upfront, out-of-pocket engine teardown fee just to "prove" the cause of failure to the warranty company. The 3. 6l v6 pentastar platform is notorious for cracking plastic oil filter/cooler housing units and failing thermostat assemblies, causing rapid coolant loss and overheating. Requiring consumers to pay massive teardown fees out-of-pocket to diagnose a known, unaddressed manufacturer design flaw creates an administrative barrier that leaves defective, dangerous vehicles on the road. Safety hazard & impact: sudden engine overheating at driving speeds causes sudden power loss, severe traffic hazards, thermal fire risks, and roadside stranding in hazardous ambient heat. This ongoing ordeal has caused severe personal distress, financial strain, and loss of wages. Requested action: I request NHTSA open a safety defect investigation into 3. 6l pentastar engine cooling failures and mandate a manufacturer recall with consumer repair reimbursement.

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.

I am reporting a potential safety issue involving my 2020 Jeep Grand Cherokee limited x. The vehicle developed a condition in which it would not stay running. I brought the vehicle to an authorized Jeep dealership, valley motor city in cuyahoga falls, ohio, for a scheduled service appointment on may 19, 2026. The dealership diagnosed and completed approximately $5,200 in repairs. On June 11, 2026, I was informed that the repairs had been completed, but the vehicle still would not stay running. The vehicle has remained at the dealership while technicians have continued attempting to determine the cause. After I escalated the matter to Jeep/stellantis customer care, I was advised that the dealership is attempting to obtain additional diagnostic information and that an engine replacement may now be under consideration. I was also advised that the dealership is expected to complete higher-level technical review procedures and may request assistance from a stellantis technical specialist if the cause still cannot be determined. I was later advised that the dealership was expected to provide follow-up information to Jeep/stellantis by Tuesday, July 14, 2026. On the evening of July 14, 2026, the Jeep/stellantis case manager advised me that the dealership had not followed up with her, and that she would follow up with the dealership and escalate the matter to her manager. The vehicle remains unresolved after 2 months of diagnosis and repair efforts. I am reporting this because a vehicle that stalls, shuts off, or will not remain running may present a safety risk, particularly if the condition occurs during operation. I do not know the root cause and do not want to speculate. I am requesting that this report be recorded as a potential safety issue involving a 2020 Jeep Grand Cherokee limited x.

Vehicle had a strong odor of gasoline then started spuddering and then caught fire while driving.

I am submitting this complaint to report a serious safety concern involving my 2020 Jeep Grand Cherokee. At approximately 44,000–45,000 miles, the vehicle suffered a catastrophic engine failure. This was extremely alarming considering the relatively low mileage of the vehicle. The most serious concern occurred while I was attempting to drive the vehicle to the service center. The condition of the vehicle became so severe that I genuinely feared the vehicle could catch fire while I was still inside it. I was terrified for my personal safety and concerned that I could be seriously injured. This was not simply an inconvenience or an ordinary mechanical repair. In my opinion, the circumstances surrounding the engine failure created a potentially dangerous safety situation. The vehicle has subsequently remained at the dealership/service facility for an extended period while the engine issue has been addressed. I contacted Jeep/stellantis regarding the engine failure. Stellantis offered approximately $13,000 in goodwill assistance toward the repair while requiring me to contribute approximately $3,200. However, my primary reason for reporting this matter to NHTSA is not the financial dispute. My primary concern is safety. I am extremely concerned that an engine could experience such a catastrophic failure at approximately 44,000–45,000 miles and create circumstances in which I feared the vehicle could catch fire while being driven. As a result of this incident, I have completely lost confidence in the safety and reliability of this vehicle and do not feel safe driving it again, even if the engine is repaired or replaced. I respectfully request that NHTSA review this complaint and determine whether similar engine failures, fire-related incidents, or safety complaints have been reported involving 2020 Jeep Grand Cherokee vehicles or vehicles equipped with the same engine. I am prepared to provide my VIN, dealership repair orders, diagnostic information, service re.
