Engine And Engine Cooling Problems of Jeep Grand Cherokee - part 2

I am filing this complaint regarding an unresolved safety recall (recall 78c) on my 2024 Jeep Grand Cherokee 4xe, which has now been open for approximately 139 days without a remedy. This recall involves engine manufacturing contamination that may lead to catastrophic engine failure, loss of propulsion, and potential fire risk. Despite the seriousness of the recall, stellantis has failed to provide a remedy and has given conflicting and unclear guidance regarding safe operation. At one point, I was instructed to operate the vehicle using the gasoline engine only. I was later told stellantis cannot provide technical guidance and to contact the dealership. The dealership has stated they have no clear direction from stellantis. As a result, I have no clear understanding of whether it is safe to operate the vehicle, use electric mode, or rely solely on the gasoline engine. Restricting use to the gasoline engine also prevents use of the plug-in hybrid system, meaning the vehicle cannot be used for its intended purpose, resulting in increased fuel costs over several months. I have also incurred out-of-pocket rental car expenses during recall service. Stellantis indicated reimbursement would be available but has not provided a process or responded to follow-ups. Given the nature of the recall and lack of guidance, I cannot determine if this vehicle is safe to transport my newborn child. At this point, I am concerned with both the unresolved defect and the manufacturer’s failure to provide consistent safety direction, communication, or a path toward resolution.

Vehicle: 2019 Jeep Grand Cherokee engine: 3. 6l v6 (pentastar) while driving on the highway, the vehicle experienced a sudden engine overheating condition, followed by a catastrophic failure of the coolant recovery tank. This failure created a serious safety hazard and appears to be the result of a known and well-documented head gasket defect in the 3. 6l engine used in Jeep Grand Cherokees. While driving at highway speed, the vehicle was operating normally until I made a left turn. Immediately after the turn, the engine temperature began to rise rapidly, indicating an overheating condition. I turned around and began driving back toward my residence to avoid further damage or a roadside breakdown. Before reaching home, the coolant recovery tank violently exploded, releasing coolant throughout the engine bay. As well as strong burning coolant chemical smells throthis occurred while the vehicle was still in operation and could have resulted in loss of visibility, fire risk, or complete engine failure while driving. After inspection by a qualified professional, the failure was confirmed to be caused by a failed head gasket, which allowed combustion gases to pressurize the cooling system until the coolant recovery tank ruptured. This failure occurred without warning and while the vehicle was being driven on public roadways. A sudden coolant system explosion and rapid overheating can result loss of engine power while driving fire risk from hot coolant contacting engine components loss of vehicle control stranding occupants in unsafe conditions this represents a significant safety defect. Jeep Grand Cherokees equipped with the 3. 6l engine are widely known to experience head gasket failures, typically occurring between 50,000 and 75,000 miles. Despite this known issue, stellantis/Chrysler has not issued a recall, technical service campaign, or extended warranty related to this defect.

I was driving on the highway when all of a sudden my gas pedal stopped propelling the car and the engine seemed to be off. I looked at the dash board and saw that the car was indicating it was off and that I needed to step on the brake and hit the ignition button to turn it back on. I barely had control of the car but was able to pull off to the side of the road. I then had to wait several minutes for the car to respond and turn back on. This has happened in the past to me with this car but this is the first time I knew I could report it here. This is a terrible vehicle and I’ve had nothing but safety issues with it since I leased it.

I am the owner of a 2024 Jeep Grand Cherokee 4xe which is currently subject to two urgent safety recalls: recall 68c (NHTSA 25v-741) regarding a high-voltage battery fire risk, and recall 95b (NHTSA 25v-766) regarding engine sand contamination. On March 13, 2026, I attempted to have these recalls addressed at an authorized dealership (brooksville Jeep). I reported two specific safety symptoms: abnormal loud engine noise during acceleration and shifting, which is a documented warning sign of catastrophic engine failure under recall 95b. Significant electric range depletion (a 10% drop from 32 miles to 29 miles), indicating potential battery cell instability under recall 68c. Despite these reported safety symptoms and the official "park outside / do not charge" advisory, the dealership and the manufacturer's recall department refused to provide a loaner or rental vehicle. They instead placed me on a "waitlist" and instructed me to continue driving the vehicle. By refusing to provide a safe, non-defective loaner vehicle while remedies are "under development," the manufacturer is forcing me to operate a vehicle that is a documented fire and stalling hazard. This puts my safety, the safety of my passengers, and my property at risk of a thermal event or a sudden loss of propulsion on public roads.

This vehicle has experienced repeated mechanical and electronic failures since delivery, including hybrid drivetrain faults, heating system malfunctions, and multiple diagnostic repair attempts. The vehicle is also subject to active safety recall 78c, which identifies a manufacturing defect that may cause catastrophic engine failure and vehicle fire risk. The manufacturer has acknowledged that a repair remedy is currently unavailable. The dealership that sold and serviced the vehicle has also recently ceased operations following acquisition by carvana. These conditions materially impair the vehicle’s safety, reliability, and usability.

The vehicle will shut down while in gear and driving at lower speeds. Happens at least 2-3 times per day for last 3 weeks.

I am submitting a complaint regarding NHTSA recall 25v-766 affecting my Jeep 4xe vehicle. This recall states that engines may have been contaminated with sand during manufacturing, which can lead to catastrophic engine failure, sudden loss of propulsion, or vehicle fire. My vehicle currently shows the recall as open with the status “remedy not yet available / parts unavailable. ” this means there is no repair available to address a known safety defect involving potential loss of propulsion and fire risk. I am concerned that sudden engine failure or loss of propulsion at highway speeds could create a significant crash risk for my vehicle, my passengers, and other motorists. Operating a vehicle with a known defect that could cause sudden engine failure while driving presents a potential crash hazard to occupants and other motorists. Owners are being asked to continue driving these vehicles despite the manufacturer acknowledging the defect and not yet providing a remedy. I respectfully request that NHTSA review the handling and timing of this recall to ensure a timely repair solution is provided to affected.

High voltage battery (hybrid battery) has excessive drain when parked. This was noticed after completing the 68c recall. In any temperature it drains 8-12% over 12 hours. I noticed it happening when it was 65-75 degrees, so not hot and not cold. I brought it in for a repair once, it spent 3 weeks at the dealership and was claimed fixed but it's still doing it. It is known problem on the forums as well after the 68c recall. No warning lights.

The contact owns a 2014 Jeep Grand Cherokee. The contact received notifications of NHTSA campaign numbers: 22v406000 (fuel system, diesel) and 23v411000 (engine and engine cooling); and requested to be removed from the recall distribution list. The local dealer and manufacturer were contacted.

Issue 1: after several recalls - the battery issue still remains. Often not kicking in and leaving a power deficit (loss of motive power). The gap is short, but when low speed on battery and you push the accellerator to merge/turn, etc. And there is a delay - it can cause an accident. Issue 2: the investigation of alerts of pedestrians - happens intermittently. There has never been a fix. Issue 3: the tire pressure monitoring system fails to read intermittently - a warning on the dash indicates it is not working and to get it checked. Dealership has noted problem, but never fixed. Still occurs 3+ years. Issue 4: radio/infotainment system blanks out or becomes unresponsive. When relying on this device for navigation, that becomes a problem.

I am [xxx] , lessee of a 2024 Jeep Grand Cherokee limited 4xe, VIN [xxx] . This vehicle is subject to three open safety recalls, including fca recall no. 78c (NHTSA 25v-766), which states the engine may be contaminated with sand from the casting process, leading to catastrophic engine failure, vehicle fire, or sudden unrecoverable loss of propulsion. Stellantis has confirmed there is no available repair and no parts — the recall status reads "parts unavailable" and "incomplete. " I am a father of three young children. My wife and I use this vehicle daily, including to transport our kids to school. Every day we face the impossible choice of putting our children in a vehicle the manufacturer itself says could catch fire or lose all power without warning. I reported this to the dealer, westbury Jeep, on February 10, 2026. They acknowledged the danger but said that replacement vechicles can only be provided by the lessor, stallantis. I then wrote to stellantis's executive team. The only response came from [xxx] , customer care & experience executive referrals manager [xxx] , [xxx] ), who offered to cover two lease payments and a gas card. She asked me to send my lease information so stellantis financial services could follow up. I sent it. Stellantis financial never responded — not a call, not an email, nothing. I am requesting that NHTSA investigate stellantis's post-recall conduct and contact [xxx] regarding my case (xxx xxx). Despite acknowledging a life-threatening defect with no fix, stellantis continues to collect $590 per month in lease payments while leaving my family in danger. I need a safe replacement vehicle immediately and a full refund of all payments made on this unsafe vehicle. Stellantis's response has been wholly inadequate.

On February 28, 2026, while preparing to leave our home with our two children in the vehicle, we experienced a critical vehicle malfunction. Upon attempting to start the car, all dashboard warning lights illuminated, including transmission error, “service needed,” and “automatic emergency braking system needs service. ” the battery warning light was also on. The vehicle would not start initially. After eventually starting the car, we temporarily placed it in neutral and pushed it out of the garage, during which the brakes functioned normally. The vehicle was briefly driven and appeared operational, but due to ongoing safety concerns and multiple recalls, we parked it at the top of our driveway. On the following day, the vehicle would not start again. We arranged for it to be towed to the dealership. On March 2, 2026, when the tow truck arrived, the car’s position prevented loading onto the truck. Multiple jump-start attempts failed initially, then briefly started the vehicle, but it immediately shut off again. We placed the vehicle in neutral using the manual override and tested the brakes, which initially showed stiffness but were operational. While attempting to move the vehicle to allow tow truck access, the brakes suddenly failed. Despite pressing the brake pedal fully and brake lights being illuminated, the vehicle did not stop and rolled uncontrollably into our garage. Consequences: •garage property damage: approximately $11,000 •personal injury: my father-in-law fell while the vehicle rolled out of control •vehicle remains at dealership with an open case, but the situation remains unresolved safety concern: this incident raises serious safety concerns regarding the reliability of the braking system and vehicle electronics. The vehicle became uncontrollable while brakes were applied, posing a direct risk of injury or death to occupants and others. We fear that similar failures could occur under normal driving conditions, including highway speeds.

While driving at highway speeds, with no warning, my vehicle shuts off forcing me to perform and emergency exits. In these situations, I have observed the dashboard screen directly in front of me read: vehicle not in park.

Had the abs module repaired due to recall last week. Next, I have had 3 instances of the accelerator sticking when shifting gears and, this never happened before this service.

The above checked and visibility wiper and auto emergency braking lights come on occasionally for no reason while driving the touchscreen can get very hot and go blank at times the electric battery is not able to be utilized in cold or hot outdoor temperatures the heating system on highest temp occasionally blows cool air -not warm/hot the engine light came on last week and the electrical power system will not engage even with full charge.

Nothing has malfunctioned yet, but this recall has been outstanding since November, 2025, and today is the last day of February, 2026. No remedy is available and its been four months.

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.

* upon normal driving the vehicle suddenly began to run rough. At that point the engine light came on and began flashing. Yes, it is available for inspection * I was traveling at highway speeds with my two young son's in the vehicle, when out of nowhere we experienced a major loss in power, forcing us to get to the far right lane and off on the next exit. * the problem has been confirmed (passenger side intake camshaft has 5 out of 6 lobes significantly worn off. . 119" of material missing as well as 2 holes on cylinder 6 piston. * it was inspected by and independent mechanic who discovered the damage to the camshafts and the piston. 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.

My 2024 grand Jeep cherokee 4xe was purchased brand new in 2025. Since then it was been in the shop on numerous occasions. Recalls with no remedies. The car lost power on the interstate with my child in the car. This is going to cause death or serious injury. This car needs to be purchased back by Jeep. I am paying on a loan for an undriveable car at no fault of my own. I was told by the car salesman that this vehicle was in great condition. They knew the issues when selling me the car late last year.

National highway traffic safety administration vehicle safety complaint complainant: [xxx] [xxx] [xxx] vehicle: 2021 Jeep Grand Cherokee ------------------------------------- safety defect complaint – post-repair vehicle condition I am reporting a serious safety concern involving my vehicle following collision repairs performed by gerber collision & glass under a claim handled by state farm insurance. After the repair, the vehicle began exhibiting multiple safety-related issues, including: - steering instability and shaking - engine performance issues and abnormal noise - hvac malfunction - persistent chemical and/or coolant odors - physical symptoms while driving, including dizziness, lightheadedness, and shortness of breath I returned to the repair facility with photographic evidence showing parts with visible wear and damage that appear inconsistent with proper replacement. Despite this, no diagnostic evaluation was performed, and no corrective action was taken. The repair facility has refused to address the condition of these parts, and the insurer has refused to authorize further inspection. Additionally, there are discrepancies between the insurance estimate and the final repair invoice, raising concerns about whether the documented work matches what was actually performed, including work involving structural components such as the cradle/subframe. I believe this vehicle may be unsafe to operate and that the repair may have introduced or failed to correct conditions that pose a risk to driver safety. I request that this matter be reviewed as a potential safety defect related to post-collision repair. Sincerely, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S.
