Car began to shake after looking under the hood found low coolant. After replacing the coolant it continued to run low only after 1 week. After second time replacing coolant engine light came on and it was taken to a mechanic who had codes come up as misfires. After replacing spark plugs and full tune up, engine light came back on. After taking it to a dealership they found a crack in the gasket at coolant passage. Car never over heated for the crack to have happened. Also seeing many other people with the same issue at the same mileage of 72k mile or less. I believe there is an issue with the head gasket.

Jeep would not start. No warning lights. Towed to the mechanic. Mechanic said starter needed to be replaced. Once the starter was replaced the mechanic noted whitish smoke from exhaust when starting the Jeep. Further diagnosis he determined the Jeep needed a head gasket replacement. As other Jeep owners have stated this came with no warning. This is a safety issue in part because the vehicle is unable to start leaving the drivers potentially started in unsafe conditions. Jeep needs to post a recall for this issue. Please advise next steps?

Crankshaft positioning sensor I’m sure my jeep falls into the recall I purchased it in march 24 and as soon as I drove off the lot with it the light came on got home scanned to find the cause and it’s the crankshaft sensor

Misfiring. Can't seem to get the check engine light off. Vehicle is too new to be having these sorts of issues. Diagnostic reader says 3rd cylinder misfire.

Been in the shop & dealer multiple times! Check engine light on for misfire in cylinder one; oil pressure sensor code. Oil case housing was replaced due to cracking! And oil pressure sensor replaced also. But still isn’t fixed and now leaks oil. Head gasket problems. Shop informed me I’ll need to replace loosing coolant going into my head gasket. Around 140k miles but problems occurred before! Jeep please explain why this is happening! A lot of money to fix it and problem after problem

What component or system failed or malfunctioned, and is it available for inspection upon request? The engine block and head are warped. Radio station keeps jumping to random station when I'm not even touching it. Auto On/Off light goes on intermittently. How was your safety or the safety of others put at risk? This could be a failure and engine lock up had I not taken it in when first troubles came about. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes and I'm told the one dealership has 3 THREE other vehicles the same make and model with the same issue! I've also read on forums that many other people have this affect theirs as well. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Check engine light went on a few times, diagnosis showed multiple misfires in the cylinder. White smoke from the exhaust and vehicle shook and acted like it was going to stall upon starting.

Intermittent extended crank on cold starts and developed a misfire in cylinder 3 and the developed a misfire and coolant leak in cylinder 1. The dealer told me it needs a new engine due to internal engine failure. Codes p0303 and p0300. Engine only has 62,000 on it.

At 47,000k miles with all maintenance being done at correct intervals. From one day to the next, check engine light came on with error code p0303; Code P0303 stands for “Cylinder 3 Misfire Detected” which indicates that there have been numerous misfires in engine cylinder 3. After taking it to the Jeep dealership they told me its a cracked cylinder head. This was a fairly common issue with earlier year WK2 models, but continues to be a under-reported issue in later years.

The alternator is pulling from the battery draining it and at 9.5 volts the car will go into safety mode where it doesn’t turn off but it won’t drive neither which actually happened to me on Saturday in the middle of the street luckily no car hit mines and the police helped me move it out the road. I complained to CArMax Kearny mesa the previous Friday and instead of them putting me in a loaner car and towing the vehicle they scheduled me for an appointment Monday (today) at 9:30am and never held up their end and I’ve been carless ever since and they had my car for 6 months fixing this same problem I’m having today .

I have a 2018 Jeep grand cherokee and one day it just didn't start. I had it towed to the jeep dealership and was told it was the starter. Once the job was done they service rwp said they will run a complete diagnostics on the jeep and get back to me. I got a call a few a days later saying the jeep had a blown head gasket, a leaking water pump and the coolant was leaking as well. They said the engine was a complete loss and to replace it and labor cost would be 14k. This jeep only has 40k miles on it and those are really soft miles, my wife literally works 5 minutes from our home and it's here daily driver. How is this possible, it's just plain ridiculous. Reaching out to jeep and got no help whatsoever. NEVER BUY A JEEP!

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 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.
