I bought the vehicle Dec 29, 2024 and it had 79000 miles on it. I use it for work , that is driving to and from my job and to the bank and back for work. I would say that in March of 2025 I went to the bank and I got in to leave and put the vehicle into reverse and it would not go into reverse and a the engine light came on. I had to shut the vehicle off and wait 5 minutes and then try again to go into reverse. When I put it into reverse the r was flashing on the shifter and it said something about needing something to be serviced. So when I looked it up it said that was a sign the transmission was failing. I drove it a couple more times and it only happened 3 times total when it was unable to shift going forward. So I took it to a shop and was informed that the transmission was needing to be replaced. There is no reason the transmission should be going out of it. I live 5 miles from where I work and 15 miles from the bank. I dont abuse my vehicles so what is there an issue with the transmission.
P0303 code. Misfire in cylinder 3. Blown head gasket. 2020 Jeep Grand Cherokee. Car is only five years old with 115000 miles. Dealer suggested a new engine. A $12,000.00 expense to the consumer. $20,000.00 still owed to bank. After much research, it’s clear as day that this is an engineering flaw. Thousands of Pentastar engines have this recurring failure.

I'm very upset as they're telling it current over the extended warranty at this time at 60,000 Miles. when I brought it in it was .. This should be a recall and they need to fix it I only had this vehicle for less then 5yrs brand new, when I started having these issues and can put me in a situation on the highway where I can get into a server accident.

Camshaft and lifter failure at 52,102 miles on Pentastar V6 Motor. This has been a known issue to this motor and no recalls. My vehicle is with the mechnic getting fixed. My vehicle was not drivable after diagnostics at my mechanic. I had potential for enfgine failure due to metal on metal camshaft. I was at risk of serious injury if I did not take my vehile in. There were no check engie lights to alert me of an issue. I noticed a slight ticking noise that was not normal. Could not be heard over the radio. Yes this problem has been reproduced at my independant service center. It has not been inspected to my knowledge by the manufacturer, police, insurance other than my mechanic. There were no warning lamps, messages or other symbols prior to my failure other than a noise I noticed when my radio was off that was not normal.
while riding vehicle just shuts off and stops. message on dash states put vehicle in park to start vehicle. Do that and vehicle starts and runs. First time this happened 6/13/25 went one week no problem then on 6/25/25 happened again took to service station no codes thrown.
[XXX] Utility 4D Altitude 4WD 3.6L V6 2020 Jeep Grand Cherokee My 2020 Jeep Grand Cherokee with 3.6L Pentastar V6 engine check engine light came on at 115,000 miles with a P0305 code. The P0305 code for a 3.6L Pentastar V6 engine indicates a misfire in cylinder number five. The week prior I performed a coolant flush and fill with the proper Mopar coolant. A few days later the water pump weep hole started leaking. I replaced the water pump and changed the spark plugs. A few days after this was when the P0305 check engine light came on and I could feel the engine starting to stumble from the misfire. No indication of overheating, coolant temperature was normal between 180 F and 210 F. I kept checking the coolant level and noticed the level dropping after a few days. There was no indication of a coolant leak after replacing the water pump. No coolant in the oil, or oil in the coolant and no white cloud from the exhaust from the coolant leaking into the combustion chamber, typically caused by a blown head gasket, cracked head or block or warped head or block. I set an appointment at the Jeep service department, and they informed me the engine had to be replaced. They said they did a bore scope test and a leak down test to confirmed the coolant was leaking into the cylinder. There are hundreds if not thousands of reports from other owners of Jeep Grand Cherokee and other Jeep, Chrysler, Ram, Dodge owners reporting this same issue. The attached photos show no coolant mixing with the or oil mixing with the coolant, resulting in the coolant only leaking through the combustion chamber to the exhaust confirming the service departments findings.

The transmission went out in October 2024 and was replaced in November 2024. Since then, the valve body has been replaced twice and probably needs to be replaced again. The car does not shift into/out of third gear properly or consistently which causes very delayed acceleration. This is a safety hazard when entering the roadway, especially merging onto the highway. Chrysler is aware of the valve body being “bad” yet continues to “replace” with bad parts.
The contact owns a 2020 Jeep Grand Cherokee. The contact stated while driving at undisclosed speeds, there was a misfire coming from the engine while accelerating, decelerating, idling, and while parked. The check engine warning light was intermittently illuminated. The vehicle was taken to the dealer, who diagnosed that the right-side intake camshaft on all 6 lobes had ground away and needed to be replaced. Additionally, metal was found in the rod bearings in the engine. The vehicle was repaired. The manufacturer was made aware of the failure and opened a case. The manufacturer referred the contact to the federal safety agency Hotline to report the failure. The failure mileage was approximately 61,000.

Took to dodge dealer and they told me they have been have problems with traction control, 4x4 problems, misfiring cylinders . They spent 5 days trying to figure it out and told me it was a process of elimination . Replace rear diff motor and that didn't work, replaced TCCM, that didn't work, replaced both batteries , that didn't work, new spark plugs, that didn't work, replaced coils on the side where #1 cylinder miss fire, that didn't work. I've spent approximately $6,000 and still have same problem. I do not have unlimited funds. What should I do next?
While I was attempting to pass a vehicle on a two-lane highway, my engine started misfiring and I lost engine power and it almost caused a head-on accident. The engine had to be replaced because the camshaft was worn on bank 1 and after doing some research there seems to be a lot of issues with this engine and the rocker arms which wears the camshaft down. There was a lot of metal in my engine which caused them to have to replace it. I researched recalls and there is nothing but after speaking with the dealership they confirmed that there is a known issue with this engine.
At 100,000 miles , traction control light and 4wd service light came on. Dealer said rear diff motor replacement needed, and the TCCM . I replaced and problem still persists . Now red triangle come on dash and says pull to safety motor will turn off. Turning wheel it hesitates like it's not engaging correctly.
The contact owns a 2020 Jeep Grand Cherokee. The contact stated that while driving at various speeds, the vehicle failed to properly accelerate and experienced a loss of automotive power. Additionally, the temperature gauge raised abnormally and was almost indicating that the engine was hot(H). The cause of the failure was not yet determined. The manufacturer and local dealer were notified of the failure, but no assistance was offered. The contact stated that the engine was previously replaced due to the same failure. The failure mileage was approximately 90,000.
Driving down the interstate at 75mph, the vehicle all of a sudden lost the ability to accelerate and felt like it shifted into neutral. We were able to pull over to the side of the road safely and as we were getting out of the vehicle, we noticed flames shooting out from under the engine. My wife and I made it out safely and as we got about 100 yards away and looked back toward the vehicle, the entire front part of the vehicle was engulfed in flames. We sat along the side of the interstate and watched the vehicle burn for 20-25 minutes. We just had the vehicle in for service 6 days prior to get a new battery, a new aux battery, an advanced diagnostic, brake fluid exchange, and a fuel system service. The evening we picked up the vehicle from service, we got an email with a powertrain alert indicator. We then checked the app on the phone and everything in the powertrain section of the vehicle health report was green. I have several videos of the vehicle burning but it doesn't look like I can upload a video file.
My check engine light came on so I took my car into the mechnanic. They noted the following: "Removed intake manifold and find cylinder three spark plug appears ok. Spin engine over to top dead center cylinder three. Pressurized cooling system and find combustion in coolant. Suspect vehicle needs new head gasket." The mechanic said that is a manufacture defect that they have seen with many Jeep vehicles. I called Jeep to inquire, and they let me know that my VIN number is not included in an existing recall for this same issue. The suggested that I reach out to the NHTSB to ask that my car be included in the existing recall.
My Jeep Cherokee has lost power twice. Once while idling at a red light and once while going 70 MPH on the Interstate. The gas pedal went to the floor without resistance and would not give any fuel to the engine. The lights were still on so I didn't lose power completely, but the engine was not responding. The recent recal 25V011000 sounds like what happened to my car, but the 2020 model is not included in the recall. I have taken it to the dealership, but they could not find anything wrong with it.
Car wouldn't shift into drive. Git car towed in was told possible cam shaft issues. Car has been back 3 more times for same issue finally Stellantis replaced cam shaft. Now same problems are occurring and Jeep wants me to pay to replace engine on a 4 year old car.
This is the fourth time this has happened. I am scheduled to have the dealership begin to trouble shoot the issue again tomorrow. Upon the second time I took the vehicle to the dealership. They were unable to replicate the issue having had it in their possession for two weeks. I was driving to work this morning, driving downhill, turned on my turn indicator to take a right onto a highway on ramp, when in the middle of the turn complete electrical and engine failure. The radio, headlamps, turn signal, brake lights, power assisted braking and engine all cut out. The hazards worked, but no dash light indicator lit up letting me know. Only the glowing flash on the side of the road let me know. The dash was completely blacked out except for "shift to park to start". The steering didn't lock up thankfully, while pulling over I attempted to shift to neutral and start while in motion, nothing. I succeeded in coming to a stop on the shoulder shifted to drive, and the vehicle started right up. There were,and are no warning lights illumenated.
The contact owns a 2020 Jeep Grand Cherokee. The contact stated while driving 50 MPH, the vehicle started shaking abnormally and stalled. The RPM increased to high. The contact was able to pull over and restart the vehicle. Several unknown warning lights were illuminated. The vehicle was taken to the local dealer, where it was diagnosed and determined that the water pump was leaking. The contact stated that the valves, cylinder, head gasket, gasket case cover, gasket head cover, oil intake manifold, and oil filter housing were replaced, but the failure recurred. The mechanic performed a pressure test. The contact stated that while at a stop light, the engine seized and failed to move. The vehicle failed to shift into gear. The vehicle was towed to the local dealer, where it was diagnosed that the alternator ground wiring nut was corroded. The vehicle was repaired. The manufacturer was not contacted. The failure mileage was approximately 50,273.
Water pump has failed at 61, 573 miles. Jeep issued a warranty extension for water pumps in the 2013-2017 models. It appears they have not corrected the defects in their water pumps.
I change my oil religiously on my 2020 Grand Cherokee, which has 67,000 miles on it. I went in today to change it at Bettenhausen Dodge (Bettenhausen Motor Sales Inc - Jeep, 8355 W 159th St, Tinley Park, IL 60477; [XXX] ; Phone: [XXX] ), and [XXX] , the service manager manager, told me I had no oil left in my car. He said something went wrong with a pump or something, and as a result I have no engine oil left.. And as a result some engine oil went into the radiator and other places. Plus, [XXX] added, they don't know yet if my engine is damaged as a result. Repairing only what they can see so far (i.e., radiator, pump, hoses etc and that's only if the engine was not damaged, which ostensibly they said they would check before work begins) will cost at least $4700. I asked why no "idiot red light" (as such warning lights used to be called, and such lights have been in every car I have owned since 1972) went on to alert me that there was NO ENGINE OIL LEFT in the car?? The manager said , none of their cars has a "low oil and/or no oil light". All they have is a computer program which informs the driver when to change the oil< and that computer warning system simply is based on miles driven, and it does not inform one if there is no engine oil or low oil. I can not hardly believe there is no red light to tell a person that there is low and/or no engine oil in the car!! The technology behind "idiot red lights" informing the driver of low oil and/or no oil has been around for over 70 years. I am i being lied to? What can I turn for help?

While at a complete stop, depressed the accelerator pedal and reached approximately 30 miles per hour. The vehicle engine RPM's rose but the vehicle would not accelerate. Placed the vehicle in park and then began driving, where the vehicle appeared as if nothing occurred. This took place around 5/2023 at approximately 26000 miles. On 7/18/2023, the same incident occurred where the vehicle momentarily lost power again and would not accelerate even when the accelerator was depressed. This occurred at approximately 30450 miles. The vehicle then appeared to have no further issues beyond that.
The check engine light started appearing on the dash and the adaptive cruise control kept appearing that it was off. The light would go off and come on again and the transmission would not shift gears and I could not go in reverse. I drove vehicle to Marino Jeep and they notified me of 3 defects in the internal transmission- which I still have my warranty as the car is at 32.800 miles ONLY on the odometer. This was a dangerous defect causing my car to stall.
Per the dealership: The engine wire harness ws not sitting where it should have been, and was melted by the cadillac converter. This caused the auxiliary battery to fail, and the jump fuse block to blow.

1.The electrical/engine/powertrain systems failed 3 times. The vehicle is available for inspection. 2.As the problem progressed, the car would only go forward, no ability to go in reverse, or to be put in park. 3.The dealership replaced the ABS Module, then later the Engine Control Module. 4.Event 1: September 1, 2022 Warning light for the stop/start feature came on, also the ABS light and check engine light. Dealership kept the car for the day, did a diagnosis, returned the vehicle stating it was safe to drive, and that an ABS Module had been ordered. Would contact me to schedule the repair. Event 2: September 8, 2022 Dashboard lit up like a Christmas tree, all warning lights came on, as well as all lights on the gearshift panel/center console, which kept blinking. Car would only go forward. Dealership installed ABS Module and returned the car to me. Event 3: September 29,2022 Warning light for the stop/start feature and check engine light came on again. I took the car to my local dealership with major concerns that the previous repair was not the only problem occurring and left it there. The Engine Control Module was eventually replaced. 5. I had no use of my Jeep Grand Cherokee from September 29 until November 8, 2022. 6. I have a major concern about the safety of this vehicle.

The vehicle when drive shuts engine off and tell you to shift to park. It has don’t it to me a few time and twice I almost got rear ended. I took it to the dealer and they say they can’t find anything wrong with it. To shut off the stop start system but it still does it when I stop start system is off. If you go online a lot of people are having the same issue Jeep just doesn’t want to acknowledge it. This is very dangerous because it does it at any speed stop and go or you could do 65 on the highway and it does it in jeep is aware of this because many people have complained about it and it’s going on death years. After some time, the system completely shut off and I was able to drive it without the stop start system. The message that came out was stop start system needs servicing, but the jeep dealer has no idea what that is. They have tested the battery and they said it’s OK. It Hass to do something on the transmission or something yeah true but this is going to be something if they don’t fix someone’s gonna get hurt and when they get a lawsuit that’s what you’re gonna do something for the negligence.
