| Jan 2025 | ENGINE | 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.

| Jan 2025 | UNKNOWN OR OTHER | The screen on the Uconnect/stereo system has de-laminated. This causes ghost touches and the screen jumps around on its own. Controls switch on their own, from media, to navigation, to climate, to controls, etc…It will also make phone calls on its own and has even dialed 911. This all happens while driving. It causes a huge distraction which is a safety issue. It also makes the whole system inoperable. Based on my research this is a very common issue with 2018 Jeep Grand Cherokees. | Crash: No Fire: No | Unknown |
| Jan 2025 | POWER TRAIN,ENGINE | 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 (https://www.youtube.com/watch?v=73MgJF4bx5o) 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. Thank you | Crash: No Fire: No | Unknown |
| Jan 2025 | ELECTRICAL SYSTEM | UConnect screen delamination is causing "ghost touching" in system. Climate control, phone, music, vehicle controls - including air suspension settings, are all impacted depending on particular event. Some are just annoyance, some are safety concerns. Air suspension height adjustments and off road settings can be controlled in the UConnect screens. THE ONLY way to lock the air suspension for towing or jacking (tire repair, oil change, etc.) is through the UConnect screens. There are 1,000's of complaints about this system issue on Jeep forums, and I was surprised at the lack of NHTSA complaints when I logged in to see the status. I have video's of the system ghosting on several different screens on different dates if you'd like to have them please provide a link to upload or an email to send them too. | Crash: No Fire: No | Unknown |

| Dec 2024 | ENGINE | 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. | Crash: No Fire: No | Unknown |

So I have had a mechanic check The vehicles battery and he told me it's getting over charged by the alternator which is is regulated by the internal computer which is extremely pricey to replace.

| Sep 2024 | UNKNOWN OR OTHER | UConnect Radio - Delamination resulting in unpredictable, repetitive, and erratic touches on the screen. At this point, the screen's protective layer is separating from the display and it is causing ghost touches that activate various functions without my input. This has occurred numerous times throughout my driving experiences and occurs every time I drive. It has led to multiple unsafe consequences while driving, the main concern being that it is distracting and confusing leading to unsafe driving conditions. For example, the navigation system has suddenly switched routes, diverting me unexpectedly causing confusion, and has led to multiple near accidents in busy intersections. Additionally, the volume has randomly increased or decreased, making it hard to hear important sounds from the environment, such as sirens or horns from other vehicles. Had this occurred in a moment in which I needed to react quickly an accident could have occurred or my safety could have been compromised. Moreover, if the radio has inadvertently changed to an unrecognized function—like activating the Bluetooth or starting a call—this has been distracting pulling my attention away from the road in multiple scenarios. The vehicle has made unsolicited calls to emergency personnel which is both a distraction to me and an inconvenience to emergency personnel. Overall, the delaminating screen not only complicates my driving experience but also poses a significant safety risk to myself and others on the road. Addressing the issue promptly is essential to ensure a safe driving environment. I have tried to address this problem with Jeep directly via Uconnect and have been informed that they do not believe this to be a concern that requires addressing. The problem has been diagnosed by a Jeep dealer and has been confirmed by Uconnect directly. Additionally, the problem has occurred in multiple other Jeep vehicles. | Crash: No Fire: No | Unknown |
| Sep 2024 | POWER TRAIN | Jeep uses a transmission manufactured by ZF. Jeep claims the transmission is "filled for life" and does not require any maintenance, and never requires the oil to be changed. ZF recommends the oil be changed every 50-75,000 miles. Many other car manufacturers that utilize ZF transmissions recommend that same interval. In fact, if you push Jeep to change your transmission oil, they suggest it will void your warranty. Preventative maintenance in the form of a transmission fluid change is necessary for the health and longevity of the vehicle. Jeep is negligent in this matter. When your transmission fails, you are thrust into "limp" mode, capping your speed at 15-20 mph. This occurred to me on the highway. I narrowly avoided being rear ended in traffic traveling 65+ mph. My car has been babied, all factory recommended services have been done in a timely manner, I was not having any issues with the car at the time, and there were no symptoms, warning lights, etc at the time. | Crash: No Fire: No | Unknown |
