Sudden loss of power while driving 75mph in the fast lane on [XXX] in [XXX]. My 2018 with the 3.0ltr Eco diesel engine was involved in a sever life-threatening event That caused my engine to fail while driving and I request immediate corporate escalation! On XXX while driving in the fast lane after just fueling up not more than 15-20min prior. my vehicle suffered, for no known reason, a catastrophic engine failure. There are no codes to be found (so said the dealer) "we cant tell you what happened to your engine", the dealer has sent me in writing. All of the sudden the dashboard read, " PULL OVER AND PUT IN PARK IMMEDIATELY".... I lost all power and was fortunate to ba able to catch an off-ramp to get off of the highway. After a 350mi tow to the walnut creek chrysler/jeep dealer. They were unable to tell me what went wrong or why a simple oil/ check engine light never happened to alert the operator? I was then told it would be a $35k engine replacement? most diesel engines historically run 250,000 to 500,000 miles and up with regular maintenance... I purchased this showroom quality vehicle from a private seller... never having even been towed 1 single time in its life before this event. I need to know what recourse that may exists for me regarding this most tragic and unsafe situation... So foreign investment groups can purchase USA auto factories and turn them into horible products... and that's okay? I have driven well over 1 million miles in my lifetime. I currently own 2 trucks, an Audi A3, 8 motorcycles, and a sprinter van RV. I formerly owned an Eagle tour coach. I am an experienced rider driver of nearly 40yrs on the road. please help [XXX] [XXX] [XXX] 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.
Engine and engine cooling, Aug 18, 2026
The contact owns a 2018 Jeep Grand Cherokee. The contact stated that since the vehicle was purchased, there was an abnormally strong coolant odor coming from the vehicle. The dealer was notified of the failure and informed the contact that the coolant reservoir was recently refilled, and the odor might be due to an overflow. The contact stated that the failure persisted, and the vehicle was taken to the dealer, where the water pump was replaced. The contact stated that the water pump had been replaced approximately nine times under warranty due to the strong coolant odor and a water pump leak; however, the failure persisted. The vehicle was not yet repaired. The manufacturer was notified of the failure, and a case was filed. The failure mileage was approximately 125,000.

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.

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.

It was suggested that I return the vehicle to the dealer as it would be needing a new motor seeing as the damages were premature and catastrophic in nature. Upon initial inspection at the dealer, they failed to identify the 2 holes in cylinder 6 piston. Suggesting that the "said holes" were nothing other than flaked carbon deposits. * There were no warning lights or any symptoms that would have indicated anything was wrong.

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!

There are parts in the engine that malfunctioned and have caused fluids to leak into the engine. This is causing the engine to fail and requiring replacement. This issue started last year for me personally. The car has been to 2 mechanics and they both have diagnosed the issue , and to fix it requires full engine replacement . It’s a safety issue because the engine can lock up and stop the car.

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.

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.

1. The issue involved the engine and emissions system, specifically a cylinder 3 misfire, accompanied by illumination of the check engine light and white smoke emitted from the exhaust. The vehicle was evaluated by an authorized Jeep dealership, which confirmed the cylinder misfire through diagnostic testing. At that time, per the diagnosis, coil 3 and all spark plugs were exchanged. This did not solve the issue. When picking up the car, check engine light was still illuminated and white smoke emitted from the exhaust. The affected components are in possession of the dealership, unsure if available upon request. 2. The engine misfire and associated white exhaust smoke created a risk of engine performance degradation, including potential loss of power, observed hesitation and stalling, which could impact the ability to safely operate the vehicle in traffic. Additionally, white smoke from the exhaust can impair visibility for surrounding drivers and may indicate an underlying engine condition that could worsen without warning, increasing the risk to the driver and others sharing the roadway. The chemical smell could also nauseate the person operating their vehicle, impeding their awareness and concentration. 3. This issue was proposed by an authorized Jeep dealership, then confirmed by two other mechanics. Dealer diagnostic records document the cylinder 3 misfire and investigation related to the check engine light and exhaust condition. 4. No inspection from manufacturer, police, or insurance representative. 5. Yes, the check engine light illuminated and the vehicle exhibited white smoke from the exhaust which prompted the service visit. Auto-start was not functioning as normal, with an error displayed on screen. Engine would sometimes stall upon start up during cold temperature days. NOTE: vehicle is currently with another mechanic awaiting an engine replacement, will upload that invoice once available.

While driving this vehicle under normal conditions, the engine developed abnormal ticking/knocking noises, loss of power, and misfire symptoms that progressively worsened. The vehicle was frequently used to transport children. Due to the nature of the failure and unpredictability of progression, continued operation posed a serious safety risk. An authorized dealer later confirmed that the engine suffered a catastrophic internal valvetrain failure involving collapsed lifters/rocker arms and severely damaged camshafts. The dealer technician explicitly stated this failure mode is “typical” for this engine design and documented progressive internal damage affecting both cylinder banks, not an isolated component. This failure mode is not sudden; it develops gradually over tens of thousands of miles and can lead to sudden engine power loss, stalling, or seizure without warning. A loss of propulsion at highway speed, during lane changes, intersections, or while transporting children creates a clear risk of crash, injury, or worse. There was no evidence of driver abuse, lack of maintenance, lubrication failure, or misuse. The dealer confirmed oil condition and service history were appropriate. The defect appears to be internal, latent, and manufacturing-related, consistent with numerous consumer complaints, technical service bulletins, and ongoing litigation involving this engine family. Had the vehicle continued to be driven, the failure could have escalated to: •Sudden loss of engine power at speed •Inability to accelerate to avoid hazards •Engine seizure causing loss of steering assist •Increased crash risk with child passengers onboard The vehicle was removed from service due to safety concerns. This defect is repeatable, predictable, and well-documented, yet not subject to recall at this time. I am reporting this to support investigation into a systemic engine defect that presents a serious safety risk to drivers and passengers.

I purchased my Jeep in 2023 and have consistently stayed up to date on all required maintenance. I had no issues with the vehicle until recently, when the check engine light and the start/stop warning appeared out of nowhere. After inspection, the mechanic determined that the entire engine needs to be replaced due to severe coolant leakage. My vehicle has now been in the repair shop for over three months because the engine is on national backorder. I contacted the dealership, but they dismissed my concerns and told me that once the car is purchased, it’s no longer their responsibility. I then reached out to the manufacturer requesting a goodwill resolution, given the unreasonable repair delay and the national backorder of such a critical component. Lemon law mileage limits do not apply to goodwill assistance, trade-in support, or corporate escalations. Despite this, the manufacturer has refused to provide any explanation or documentation for why they cannot assist and it has been three months with no progress. There were no warnings or indicators that something was failing internally, and my mechanic confirmed there was absolutely nothing I could have done to prevent this. I’ve also seen numerous reports of this same issue affecting my specific make and model. Stellantis needs to take accountability. It is completely unfair that I am left without reliable transportation for months over an issue that was entirely out of my control.

In September 2025, the vehicle was shaking upon idle when we started it. We did a test and learned it was somehow losing coolant. We took it to a mechanic who discovered it was burning coolant in the 5th cylinder. They diagnosed the issue as blown head gaskets caused by the engine being machined incorrectly by the manufacturer. This resulted in the need for a short block removal and replacement, resurfacing the cylinder heads, replacing the head gaskets, among with many smaller repairs. The cost was over $8,000 total for a manufacturing error. If left unresolved, this could have caused further mechanical issues and potentially a crash or other safety issues.
