THE 2014 - 2017 Jeep grand cherokee as well as many other chrysler mad 3.6lL v engines are all either past their standard warranty period or are approaching it. The problem i have specifically is that my car has under 50 k miles and i have a receipt showing it was bought in november of 2017, there for still under Jeeps powertrain warranty, and the headgasket is failing. ive been to multiple accredited mechanics before taking the vehicle to jeep how performed all the necessary test to concludits the gasket needs to be replaced. i then took it to a dealership who said " On thes 3.6L engines it extremely common for this to happen." i was then quoted 3k for the repair and dropped my car off. after 2 weeks of them having my car and me calling daily for updates i was finally told the car needs a new motor. which would cost 11k. I denied and called chrysler claims department who told me its out of warranty and I would have to pay out of pocket for the repairs before they would look into "how much they might be able to reimburse me" after searching online I've noticed this is a huge problem for many people. it seems as though Chrysler made an engine that will last 50 k miles and then have catastrophic engine failures. you might timed obsolescence. any way i hope this issue is looked into because this company, Chrysler is putting thousands of middle class Americans out of a vehicle or potentially into debt. hope to hear back soon [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

As I slow down close to a stop the car loses all power. The car will coast along with no power. I have to verve to the side of the road. The car has no power to accelerate. If I shut off the engine the computer reboots and everything is fine. I have submitted this problem to Jeep and nhtsa previously. I bought this car new from the dealer in 2017 and have had this problem starting in year one. Jeep updated the software back then. It only occurs about 1-2 times a year, but causes a very dangerous issue when it occurs.

There are a ton of posts on Reddit showing a bunch of 3.6l jeep owners all having the same issue with the VVT/VVL Solenoid. It seems to be all the same, the truck starts running very rough and like complete [XXX], CEL starts blinking, and then they check the codes coming up and they all seem to be getting codes p0456, p105d & p0302. The misfire is in cylinder 2 and the VVT Solenoid needs to be replaced at not even 70k miles. The bad solenoid caused the jeep to be undriveable. There are a ton of jeep owners who are all having this same EXACT issue with their jeep and yet this isn-??t a recall"? Jeep obviously made a faulty truck. Please explain HOW THERE ISN-??T A RECALL TO FIX THE VVT/VVL SOLENOID IN THESE JEEPS?" Some people are spending thousands to get it fixed at a dealer, which is seriously messed up bc it-??s one little part and such an easy fix and just getting ripped off. JEEP NEEDS TO FIX THIS OBVIOUS VERY WELL KNOWN ENGINE ISSUE BC THATS ON THEM, THEY SHOULD HAVE TO PAY, NOT THE CONSUMERS who put all their faith into jeep to make a good running truck, only to get [XXX]!!!

Driving down highway at 75 then the warning light for the start/stop function lights up, the jeep then starts cutting out and sounding really rough, speed immediately drops down to the 40"s this is on a major roadway luckily there were no cars behind me because they probably would had ran into me due to speed dropping that quickly thought I had a flat due to the sound pulled over as quickly as I could got out checked everything did not see anything wrong no fluid leaking, no smoke ect..get back in the vehicle go to proceed to get back up on the road and the vehicle is running really rough and jerky will not go above 40 engine light then comes on along with warning bells, pull back over on side of road turn vehicle off let it set for about 5 min. then start back up engine light is off but the start/stop light on dash is still on, then the engine light comes back on right outside of town slowly get into town take immediately to mechanic shop he checks the engine and tells me that cylinder 5 is misfiring changes coil pack and problem still shows up, I get the vehicle towed by to my home town 3 hrs away take to dealership now they tell me that my cylinder 5 has no compression and I need new engine the vehicle only has 81000 miles just purchased last July.

On April 11, 2022, after driving home from work I noticed oil dripping onto my driveway. I opened the hood of the vehicle and discovered that my cooling system was completely filled with oil and there wasn't any noticeable coolant left in the system. I then checked the oil level via dipstick, and found there to be an extremely low level of oil in the engine. Prior to pulling into the driveway, there were no warning lights, no check engine light, or low oil lights on the dashboard. Nothing to indicate a potentially serious issue. The vehicle was then towed to a Jeep dealership for repair. The dealer indicated, both on the paperwork and over the phone, that the Engine Oil Adapter Housing (Mopar Part 68308741-AF) was leaking internally, causing the oil to be redirected into the cooling system and displacing the coolant (see attached invoice from Jeep). Most of the cooling system had to be replaced due to oil contamination. This part failure could have been catastrophic had I been traveling down the road or the freeway, as a loss of oil in the engine and a cooling system not properly functioning, could have caused the engine to fail while at speed leading to a loss of power steering and braking, and possibly resulting in a crash. Additionally, as previously mentioned, no warning lights or indicators were visible at any time. From talking to the dealership and researching online, this part failure is common on all 3.2L and 3.6L Pentastar V6 engines. The dealership, at the time of my vehicles repair, had three other FCA/Stellantis vehicles in for the exact same issue. This component is made of plastic and is located directly on top of the engine block, and below the intake manifold. This area can get very hot and cause the plastic to become brittle and crack without warning. The original failed component was taken by the dealership, and I do not have it on hand. The vehicle has been serviced by the dealership, and it currently in working order. FCA is aware of the issue.

Started my 2017 Jeep Grand Cherokee after a heavy snow fall the next day drove about 10 minutes and horn started going off lights exterior and interior started flashing, faults came across the screen to service every imaginable function from transmission to power steering and everything in between and truck just completely failed on the road. Waited roughly 30 minutes truck fired back up drove about 200 feet to a gas station while waiting for a tow truck. Brought to the dealership and they flashed 9 different modules. All seemed fine until another month. Remote started Jeep went to get in dash cluster screen black. Turned off and back on cluster came back but was delayed along with heck engine light. Drove back to dealership and was told they wouldn-??t be able to look at it for 3 weeks. About a week after the cluster incident I go to leave my house, make it about 30 feet out of my driveway and truck stalls again exactly like how it did the first time. At a different mechanic now for it to get diagnosed. With the history of poorly made tipms in Chrysler products this seems to be a reoccurring theme.

Beginning two months ago my passenger side front window began rolling down on its own and the dash board lights would continually flash on and off. When at a stop sign or red light the vehicle idles down as low as 9. The battery was checked by the dealership and I was told it did not require replacement. The tachometer drops to zero while the vehicle is in motion and on two of those occasions the vehicle just shut off. When these incidences occur, which has been regularly for the past two weeks, upon exiting the vehicle I receive several palpable electric shocks. The car is now parked because I am afraid the car will set afire. I have been told by several dealerships that they can't get me in for a week or more to check the issue. I am very concerned for my safety due to this electrical issue, especially receiving the shocks.

Hello, I was driving my 2018 jeep grand Cherokee about 2 months ago when out of no where the car turned off as I came to a hill, the radio volume increased all the way and I couldn't control it, the main break locked, the wheel locked and my shifter lock, I started to roll back down the hill and I had to use my e-break. the car acted like it was turned off but it just died, the radio never turned back down until the tow company did something. i took it to jeep and they were super unhelpful, they said it was a starter, so i paid 2000 to replace the starter to no avail. Now the AC/Heat goes on by itself or just doesn't work, the radio will go all the way up and i cant control it. however jeep in Englewood Colorado said there is nothing wrong with the car.. I think there is a safety issue with the start stop /eco mode. I think once the car turns off to save gas its not turning back on and there is no safe system. i have contracted jeep multiple times to no avail, the car has died on the highway 3 times now once while i was traveling 65 mph. I have paid for 6000 worth of fixes and its still happening.

On October 02, 2021, While driving at highway speeds the engine stopped running and the tachometer went to zero RPM. I was able to shift to neutral and cruise downhill until I could safely pull to the side of the road. I was able to shift back to park. The vehicle would not restart for approximately 20 minutes. During this time the electric windows would not roll up or down, the electric tailgate would not open but the electric drivers seat would work. After about 20 minutes the car restarted as if nothing had happened. The same thing happened 3 more times on the way home that same day. The same thing had happened 3 times over an 18 month period in 2018-2019. At that time, the jeep dealer could find no problems.

Midway through a 2.5hr. drive, I approached a stop sign to make a right hand turn. When I came to a stop to check for oncoming traffic, the Jeep completely shut off on me. The cluster panel displayed -??Shift to P to start-?? and the cluster panel was flashing all the warning lights. (vehicle was still in the ON position) I had then shifted the vehicle to Park, shut off the ignition and then restarted the Jeep. A very scary situation to happen during a normal drive. I have done some browsing and see that I-??m not the only one who has encountered this problem. Due to the extreme safety issues at hand, I truly believe Chrysler should be investigating this underlying issue. (I-??ve read some people have experienced this while driving on the main road with traffic. I-??ve also read that one person experienced this and it ended in a vehicle accident.) This is a serious issue.

The power to the engine comes to slow motion with no power to accelerate. It is like the transmission has no power, but no noise. This occurred when turning or stopping. At a street light.
