The head gasket gets blown with 50,000 miles for the 2018 grand jeep Cherokee high altitude. Went to jeep dealership in Downey and they said they knew it would be the head gasket they had other jeeps in the shop with that same problem, but wanted to charge 5000 just to confirm. So then we went to a mechanic in Los Angeles and they had 5 other 2018 jeeps in the shop with the same problem. The 2018 jeep grand Cherokee 3.6L is having so many problems with the head gasket at such low miles this needs to be recalled! How is it a good supposedly reliable car is breaking down so early. This is a SAFETY ISSUE IT can cause a fire !!!!

I am writing to report a concerning issue related to the water pump in my 2018 Jeep Grand Cherokee. Recently, I discovered a significant coolant leak originating from the water pump, which has raised concerns about the safety and reliability of my vehicle. I would like to bring this matter to your attention for investigation and potential action. While this issue may be isolated to my vehicle, I believe it's crucial to ensure the safety and reliability of all 2018 Jeep Grand Cherokee models. I have taken my vehicle to an auto repair shop for repairs, and they confirmed the water pump leak. Your prompt attention to this matter is greatly appreciated, and I hope that by reporting this issue, we can contribute to the overall safety and quality of vehicles on the road. Thank you for your commitment to ensuring the safety of drivers and passengers.

This vehicle will not move (intermitant problem) at times when the vehicle is placed in drive or reverse. The gear shift console and dash will flash and the vehicle is rendred useless. I have to turn off and restart the vehicle to resolve the problem. Temporary fix. It keeps happening. This vehicle has been in the shop 3 times (dealing with this issue for over a year). Noone knows what the problem is. No codes are thrown. Jeep has been contacted. Several forums I have looked at online state this problem with no resolution. The problem is someone is going to be killed or seriously injured. When it leaves me stranded in an intersection, which it did, I have a major problem. A resolution has to be found. Its not allowing me to upload video. I do have video of this happening which has been shown to the dealership and the adjuster of my extended warrenty company.

I have had 2 safety recalls open on my Jeep without remedy for over a year. FCA has failed to do anything putting me and my family at risk.

The stop/start feature on my Jeep has just stopped working. The battery has been checked and rechecked and replaced. It doesn't work. The biggest problem now is the 8.4 touchscreen display that malfunctions. The GPS is connected to this along with the radio and backup camera. Other features include the phone, climate control, and other functions. The phone will randomly select contacts I am not trying to call, and the GPS will randomly set locations I am not trying to go. The screen will jump from one application to another which is extremely distracting while driving. I've tried turning the screen off completely but this isn't helpful if I'm actually using my navigation. It's dangerous.

Starting around February 23 after about 10 minutes into driving. The hot temperature lamp would show up. I pull over an it was always empty of coolant I had done that few times within one week. I also didn-??t use air conditioning for a few weeks left. An it was ok for few weeks. Then I noticed smoke coming out back pipes. Send to first reipair shop. They found Coolant in a combustion chamber They told me I should send to Jeep shop.

I attempted SEVERAL times to have the Stellantis/Chrysler/Jeep 'Z46 - High-Pressure Fuel Pump Failure' recall repair performed on my 2018 Jeep Grand Cherokee Summit Platinum 4X4 EcoDiesel. The 'Z46' recall was issued in JUN 2022. Yet over ONE YEAR LATER each time I inquire about performing this recall repair the Jeep dealer advises that "there are no parts available to perform the recall repair". I submitted a complaint to Stellantis/Chrysler/Jeep Customer Assistance and asked that the problem be escalated. I received no response or further follow up to that complaint submission. I need to sell the vehicle in the next 30 days but cannot sell the vehicle due to the open Z46 recall. I am suffering economic injury as a result of the Jeep dealer's inability to perform the Stellantis/Chrysler/Jeep 'Z46' recall repair.

Jeep issued a recall for the high pressure fuel pump on our 2018 Grand Cherokee about a year ago and a redesigned fuel pump by Bosch is still not available. I am unable to travel out of state for fear that the fuel pump will fail possibly causing a crash or leaving me stranded at my own expense. Why have a recall if the manufacturer can just ignore it and start discontinuing the product which Jeep has started to do at the beginning of 2023. Repeated attempts to get service from Jeep for the recall have resulted in the message no parts available. What is NHTSA doing about this recall?

2018 Jeep Grand Cherokee with 55,575 miles was parked in a parking garage all day in Brooklyn NY and when the vehicle was move to the front of the garage by parking attendants the engine started smoking and caught fire. There were no leaks, dashboard symbols or open recalls to cause the fire; additionally the car was linked to a iPhone App CarRx that can scan for any issue and no issue noted. This engine fire not only put all of the other vehicles in the park garage at risk of catching fire but the parking garage sits under a luxury apartment building putting the working and residents at risk. Additionally I commute between Brooklyn and NJ 3x a week and cant imagine what would have happened if I was driving the vehicle over the Brooklyn Bridge, on the Brooklyn Queens Express or in the Holland Tunnel during high commuter rush hour traffic. Car was checked out by a Jeep Dealership who confirm fire was not caused by any leaks or electrical issue but did mentioned it seems to have started around the engine air cleaner. The current status of the issue has been an open investigation with Jeep Corporate for going on the 3rd week with no communication or updates on status. The entire issue and fire from pulling into the garage to the when the car was moved to it smoking and catching fire is all documented on security video.

There is an electrical failure that causes the blinkers to stop working, shortly after noticing this issue the vehicle will fail to start after travelling to my destination. This has happened more than twice and there are no recalls shown for the "Limited" version of this vehicle. The standard edition seems to have confirmed recalls for the same issues that the Limited version is experiencing. A mechanic has described an electrical short circuit. I encourage looking into the different models of the 2018 Jeep Grand Cherokee in which you'll definitely find the same safety issues described online by many others. These repairs need to be addressed and repaired by the manufacturer. Thank you!

October 31, 2022 - Check Engine Light came on. Autozone gave me the P0456 code - Small Leak in Evap System. The check engine light went off a week later. Continued to come on/off for the next 2 months. I was able to finally get an appt on 1/9 and took it into San Diego Jeep Dealership on Camino Del Rio S. They charged $500 for diagnostic even though I had the code already and replaced the Purge Valve & Hose. On 1/14 my car engine would not start at all. On 1/15 my car engine started, I went to drive and within a block my car shut off on me and I coasted to the side of the road while it threw a bunch of different errors including electronic stability warning. I came to a stop and then all of my windshield wipers randomly started going off, my horn randomly started going off, and the lights in my car started flashing. I pressed the push start button to try to turn it all off. I then got the error meesage that my front left headlight was out, it now is, alos my left blinker now doesn't work properly. I tried to start the car again, no luck. I called a tow truck, the tow truck guy was able to get my engine to start. I explained that my car shut off and asked him to follow me for a little while. I got 2 blocks and came to an stop sign where I idled and my car engine shut off on me again. I had my car towed back to the dealership that did the work. On 1/16 they told me it would be $700 for an electrical diagnostic. I did not have any major problems or warnings before taking it to the dealership.

I bought my Jeep Grand Cherokee in the end of February 2021 with approx. 52,000 miles on it. All work done to it after this point has been under warranty with me paying all of the deductibles for the warranty work. A couple of weeks after purchase, the problems began. It was overheating, white steam coming out of my exhaust pipes, vibrating very badly, shutting down at traffic lights, amongst other symptoms. As of now, the dealership has replaced 3 new water pumps, and 2 new cylinder heads (both times were issues with the 3rd cylinder). This go round, it-€™s now back in the shop with another misfire with cylinder 3. The dealership has also replaced the EGR Cooler, Ignition Coil, Motor Mounts, Coolant Flush, Lifters & Rockers & it is still in the shop. All repairs done by the same shop (different technicians throughout the past year and a half). I thought it might qualify under the lemon law and called an attorney who asked me some questions but said that it does not qualify in my state under the Lemon Law because it-€™s now past the 60,000 milestone. It now has approximately 85,000 miles on it. I have been without a vehicle approximately 6 months out of the past year and a half and multiple rental car fees (though the dealership absorbed the majority of the fees when it was in the shop this past June/July). A few of the reasons all of this is most upsetting to me: - My daughter and I have broken down on the side of a busy interstate twice (once in the middle of the night) and had to try to get off of the interstate safely so we could be towed - I have been faithfully paying my 'new-to-me' car note ever since I bought it but haven't had much of a chance to drive my 'new' vehicle - My daughter recently got her driver's permit & can't learn how to drive as we are in a rental & it is against the rental company policy to allow anyone else to drive their vehicles. - I have had to take off of work MANY hours due to this This is holding up our lives!

My pre-owned 2018 Jeep Grand Cherokee 4x4 Trailhawk is unsafe and unreliable because the vehicle ** would not start ** on three occasions within 18 months of ownership. Also, the "auto start" feature on the key fob works intermittently. Thankfully, I was in safe locations when the problems occurred, but two of those locations were in public, away from home. Also, the dashboard has indicator lights that come on randomly such as engine or start/stop or "check air suspension" or check ABS. The dealer has not been able to find or diagnose the problem, yet I keep paying out of pocket fees. My problems would occur with no warning, so there would be no time to get help. I contacted Chrysler on 8/8/22 and they were no help; they just directed me back to a dealer to pay another out-of-pocket diagnostic fee. They expressed no concern for my safety, did not acknowledge my frustration, and said a supervisor was not available to speak to me. All recall work was completed prior to my owning the vehicle. I do not trust my own vehicle and I need to travel frequently through desolate and arduous terrain. I am likely going to get rid of the vehicle because (1) I don't trust Chrysler or government systems to help me in the timeframe that I need help, (2) I need to do my job and have a peace of mind, and (3) I need to know that I and my family will be safe.

The vehicle stalled while driving on a busy road. It sounded like it couldn-€™t shift gears. It also accelerated once I tried to move it to a safer location on the side of the road. It was very scary not knowing if I could get out of the stalling situation in the middle of traffic. The unexpected acceleration upon trying to park it safely was also terrifying.

There are numerous safety issues with this vehicle. The most concerning is electrical/fuel/engine relating to the TIPM. The vehicle intermittently refuses to start. The integrated fuel pump relay in the TIPM fails. This has left my wife stranded in potentially dangerous areas. It has also died while the vehicle was in motion. In addition to the TIPM issues, the digitizer of the factory radio/navigation system has delaminated from the LCD screen. The safety issues this causes are multiple: random phone calls while driving (distracting), random radio station changes (again, distracting to a driver), and an inability to properly utilize navigation (potentially dangerous if it tries to change a route and indicates last-second turns). It also prevents the driver from calling someone if they are in need of help. Not only does hands-free calling not work, but even when taking out the phone to dial, the haywire behavior of the device being connected via bluetooth makes calls difficult. These are known issues by the Jeep dealer with frequent warranty replacements admitted by the advisor and technician, yet they have been zero assistance in helping because the vehicle is out of warranty. It will require action from someone like the NHTSA to get Jeep to correct these problems for many owners. It is criminal to charge people this amount of money for a vehicle that simply doesn't do what it is supposed to do.

I purchased my 2018 Jeep Cherokee right off the dealership lot in Lynnfield MA in August of 2018. I then have had on going issues. Starting with strange squilling sound coming from back of vehicle, this was never found reason by technician but they replaced engine air filter jume 2020, then my heater wasn-€™t working in dec.2020, replaced motor blower with wheel, then may2021 my vehicle just shut down as I was driving on the highway to work at night no prior warnings beforehand, lucky no one was hurt towed in and no start and transmission was stuck no fuel pressure, dtc related and shorted fuel pump. Replaced module fuel pump level unit. Now just October 29,2021 my vehicle is not starting I jumped the battery and lights come on but vehicle won-€™t start. Dealership I purchased vehicle from won-€™t contact me back so I towed the vehicle to them and still no response. I-€™m very disappointed in Jeep I don-€™t feel safe or that my vehicle is not dependable and for all the money I keep putting into it I should have a dependable car.

We have experienced 2 separate episodes of this vehicle suddenly becoming disabled with complete engine shutdown while driving at highway speeds. Both episodes occurred abruptly, engine idling extremely rough, then shutting down within seconds, leaving the car completely inoperable. Both episodes were very dangerous as the car could barely coast to the shoulder of the highway for safety of the passengers. The first episode occurred when the car was a few months old, gas gauge showing over 1/4 tank of diesel gas. Car was towed to the Jeep dealership where they claimed that the car simply ran out of diesel (despite the gas gauge indication) no repair "was required", car filled with several gallons of diesel and OBD codes reset by the dealer, car then ran normally. The second episode occurred one week ago. Again driving at highway speed, 5 lane highway, over 1/4 of diesel remaining on the gauge, sudden violent engine running, sudden full loss of function of the vehicle, nearly in an accident simply trying to " limp " to an emergency stop on the road shoulder. Car required towing to our residence. with the prior experience at the Jeep dealer, despite gauge reading of greater 1/4 tank, the car was filled with 5 gallons of diesel, car started normally. All OBD fault codes insufficient fuel to the engine, fuel rail, fuel pressure, etc. The car has run normally since. I contacted my Jeep dealership and they stated they have no knowledge of any similar issues with this Jeep Diesel engine. The internet and Jeep car forums are filled with identical Diesel engine problems. Either related to faulty fuel pressure regulation or some design fault with fuel level indication affecting the safe operation of this Jeep Diesel engine. these problems date back to pre 2008. We now feel very unsafe to drive this relatively new 2018 Jeep Diesel Grand Cherokee at highway speeds without hovering near the shoulder lane of the road.
