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.

I have been without a vehicle for over 5 months. Paying on a vehicle that I cannot even get out of the garage. Paying storage insurance on a vehicle. There is a major issue with camshafts right now. I have had the spark plugs changed, coils, oil and I was waiting on the camshaft which is on back order for who knows how long. This needs to be addressed and recalled. With the amount being over 14,000 parts on back order I think this should be recalled. Even people who have had the camshaft fixed are still having engine issues with the 3. 6l. Please do something about this, I have put so much money into this and I need a vehicle. At 75,000 miles this should not be happening.

Grandfather bought the car for me in December 2024. It was sold and wasn’t told there were any issues with the car. It was bought in texas. I drove it to colorado. Two and a half weeks into driving the car, it was leaking a lot of oil. Had it looked at and was told the oil housing unit was dumping oil out of it bc it was made of plastic not aluminum. I was trying to go through extended warranty not knowing the severity of the issues of the car. I was going to have it looked at by Jeep instead of midas. They were booked out for over 2 weeks. I was trying to keep oil in the engine while waiting to get it looked at by Jeep. The engines ended up seizing on me. I had put more oil in it the day it seized up on [xxx]. I had to have it towed to pep boys just find out the engine got messed up by the crack in f he coolant and housing unit. The oil lamp came on 2 days before new year’s eve. I was trying to find a place to schedule to be looked at and couldn’t get it looked at until after the new year. I had called greg may Honda back in texas to double check to see if they changed the oil before they sold it and said they did. I barely put over 1200 miles on the car since it was bought off the lot. I started doing research on it after the car engine seized up. Come to find out that there is a recall on the oil issue. I also found out that it would lead to the engine seizing up. I believe pep boys might have reported the issue as of today for a safety recall on it.

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.

Three concerns: (1) the engine light is on. Mechanics cannot determine why. (2) the car has trouble starting. When I park indoors, the car doesn't start. The engine turns over several times and the rpm goes all the way up, but the car will not start until the 3rd or 4th try. Mechanics cannot determine why. (3) when I pump gas, the fuel pump automatically shuts off even though the gas tank is not full. So I have to hold the pump in place and use the gas gauge to determine when the tank is full. Mechanics have seen this problem in other Jeeps but haven't given me a reason why.

Shifter park select a gear and engine lights on.

Please see all the reports of the same exact issue. There is an issue with the 2018 Grand Cherokee engines. This blown head gasket is now going to cost me $13,000 to get a new engine. Every report listed in this link is the same issue. Please address the issues and reimburse owners of this Jeep having to replace their engines.

2018 Jeep Grand Cherokee limited 3. 6 l v6 engines have a high rate of having head gasket problems around 100,000 miles causing vehicle to overheat and leak liquid into the cylinders damaging the engine. Please look into this problem at dealerships around the country with this year, make and model and discover how common of an issue this is with owners.

Took my 2018 Jeep Grand Cherokee vehicle in as oil was leaking badly , which could have made a dangerous situation. Was told by mechanic that my oil filter adapter had to be replaced. Was advised it was made of plastic and had cracked. The mechanic could not believe there wasn’t already a recall on this part. He replaced it with an aluminum part but this was a costly repair costing close to 1,100. 00.

The contact owns a 2018 Jeep cherokee. The contact stated while driving at an undisclosed speed, the start/stop, and check engine warning lights were illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that one of the spark plugs was misfiring and the ignition coils might need to be replaced. The independent mechanic requested to perform another diagnostic test on the vehicle and discovered that there was a blown head gasket and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 95,000.

Dear national highway traffic safety administration, I'm writing to report a critical safety concern regarding the 2018 Jeep Grand Cherokee's water pump design. As an owner, I've experienced persistent coolant leaks, which I've found is a widespread issue affecting many others. This problem stems from a fundamental design flaw in the water pump, not typical wear and tear. The issue centers on a small "freeze plug" that leaks when the engine reaches operating temperature. This plug serves no apparent purpose and causes premature failures and coolant leaks across numerous vehicles. Key points: the leak occurs consistently when the engine is hot, indicating a design-related problem. This issue potentially leads to engine overheating and severe damage. It affects many vehicles, particularly those with the 3. 6l v6 engine. Extensive research on online forums confirms this is a common problem. . Read more...

The number 4 and 5 cylinders warped in my 3. 6 engine cross motors in louisville ky is repairing the engine.

The radio randomly changes every 5 seconds, the beeping will drive a person insane, blutooth will hang up or not allow me to answer or call out. The seat warmers turn on randomly as well and I’m unable to lower the temp or turn them off. A/c in the winter and heat the summer. Auto start doesn’t work cuz vehicle shuts itself off after 30s - 1 min and navigation is useless cuz of this electrical gremlin. How long before it accelerates by itself or cuts the engine while I’m on the freeway. Safety hazard.

I bought a 2018 Jeep Grand Cherokee limited on July 1,2024. A week after owning the vehicle the Jeep kept shutting off while driving on the interstate and the dash said “ put in p and push to start” none of the hazard lights came on. It just automatically shut off in the middle of traffic multiple times and when put into park and tried to restart it would take several attempts. This is unsafe and I’m lucky I did not get into an accident since the vehicle is just turning off while I’m driving on a busy highway not to mention almost getting into an accident since I’m given no warning. I dropped off my Jeep at the dealership and they have had it for two weeks stating they can not find any issues with the vehicle. This is frustrating and scary and do not even feel comfortable driving a the Jeep that I owned for one week. I have read several complaints in the same issue and k won’t seems to be able to find what is causing this issue.

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.

Car dealer said that they already fixed the recalled issue. But we took car to the dealer also for car overheating in very short distances and the car only has about 67,300 miles. The dealer said that they "found stored dtc in pcm" p0304(cylinder #4 misfire). "there are combustion gases in cooling system. " they said the car needed cylinder head replacement and engine replacement quoting me $8001. 88 for repairs which I could not pay. The car has only been driven locally. We also suspect that this car may have been damaged by hurricane michael in florida in 2018 and damage may have not been reported. Car was bought in florida in approx. September 2018 by owner 1 who sold the car to owner 2 with only approx. 2500mi after hurricane michael (oct 9-10th). The car was sold to owner 2 in November 2018 in florida then brought to California in 2021 and sold to owner 3 who is making this report. Or car may have already presented mechanical issues that may not been reported. Car has only been driven locally.

My Jeep has stalled on me twice attempting to go through a stop sign at a busy intersection as soon as I slowed the Jeep down and then accelerated to go through the stop sign it stalled on a major hwy. No lights come on and the automatic shutoff button is turned off and for the past month the Jeep hasn’t started without either a jump or sitting a while after it was hooked to another vehicle.

The contact owns a 2018 Jeep Grand Cherokee. The contact stated that on several occasions while driving at various speeds, the vehicle lost motive power intermittently. Additionally, the contact observed a burning odor inside the cabin of the vehicle. The check engine warning light was illuminated. The vehicle was taken to a dealer where it was diagnosed that the cam shaft, oil valve, and other unknown parts needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 100,000.

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?.

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.

The contact owns a 2018 Jeep Grand Cherokee. The contact stated that while parked they noticed an unusual liquid on the ground. The vehicle was taken to the dealer where it was diagnosed as having coolant leaking into the motor and needing to have the water pump replaced. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was approximately 82,000 .

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.

Multiple leaks found under the car and was brought in for emergency repair. One leak was the driveshaft, one was engine coolant and the other was the front steering column.

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 .

Stop start comes on and will turn the car off when stopped. I have to put the car in park to restart the car. The deal said that there is no recall for this issue.

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.

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 issuse it can cause a fire !!!!.

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!.

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.

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.

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.
