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.

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. A YouTube video [XXX] ) provides insight into the issue. The creator states: "Upon digging into this a bit deeper, I don't believe it's the 'weep hole'. It's actually like a small 'freeze plug' that leaks on these pumps. If you look through the pulley at the opposite side of the aluminum freeze plug that leaks, you will see the weep hole. This 'freeze plug' that leaks serves no purpose as far as I see it. It's just like they slapped this plug in the front of the pump-?? and it leaks when it gets hot." Given this evidence of a design flaw and its widespread impact, I urge NHTSA to: Investigate the water pump design of the 2018 Jeep Grand Cherokee and similar models. Assess the safety implications, including the risk of engine overheating and potential vehicle failures. Consider whether a recall or other corrective action is necessary. The fact that this is a design issue rather than wear-and-tear underscores its urgency. All vehicles with this water pump design are potentially at risk, regardless of mileage or maintenance history.

A recall NHTSA 20V-699 was issued on our vehicle in March 2021. This is related to a Fire Hazard. The recall repair was done and component exchanged, now 3 years later and 35,000 miles we have exactly the same issue. A cracked EGR cooler, same as previous. My concern is that the replaced part is from the same batch as originally and as such they replaced a dangerous part with another dangerous part. The dealer and FCA refuses to replace the part as they say the recall has been closed. I my opinion this Fire Hazard still exists and repair was not done with a quality product, as it is exactly the same issue. as before.

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

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.

The EGR Valve, Diesel Particulate Filter, and Intake Manifold failed at 88k miles. The EGR was replaced at 49k miles on October 4, 2021. The vehicle was taken to the dealer for MIL. The estimated repair cost is $11k. All components are filled with carbon deposits. The emissions system should provide a longer life than 88k miles. Is there a possible design defect with the emission ?

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 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.

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?

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.
