2017 JEEP GRAND CHEROKEE Complaints

Problem in transfer case, can’t use 4WD, ACC and FCW are not working. My car has only 41000 miles and I am reading about many, many others having the same problem. Jeep should recall this problem!! Thank you

I noticed a clanking noise when backing out of my drive. Dealership reported that they have had this issue a couple of times. The nut holding the drive shaft and transmission together backed off and has damaged the drive shaft, yoke, and flange causing the drive shaft to move around this the clanking noise I’ve been hearing. My vehicle has been in the shop for 4 months know because they are unable to find the flange needed to complete the repairs. I have owned this vehicle less than a year and am being told that this has been turned over to Chrysler to handle now since the part is not manufactured anywhere.

The transfer case on this Jeep failed at just over 64,000 miles. As the service center tried to repair, they were unable to locate rebuilt/certified transfer cases due to high demand. A new transfer case was purchased. The core charge (fee to return old transfer case) for the service center was $1000 indicating to me that the old, failed transfer case is in high demand for rebuilds due to a common failing part. The failure of this part locks the vehicle in 4WD low. The cost of repair for me was over $2500.

A pickup truck struck driver side of car, while truck was traveling over 50 mph, and side air bags did not deploy

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 .

My wife and kids almost got killed in this vehicle twice this week due tot The Can Bus electrical communication network stop working. It completely stopped on the highway while driving 70 mph and almost caused a multiple car accident. All the controller icons lighted up on the dash board and the car shifter and transmission stopped working. I towed it to the dealership and paid 700.00 for a new shifter. The next day the vehicle did the same thing. This is a dangerous situation that needs to be recalled ASAP. Someone is going to get killed driving one of these vehicles. I researched this problem and numerous reviews found on the same issue 2014-2022 all electric Can Bus operated drivetrains jeep. Please recall my 2017 Jeep before it kills my family and you will have a astronomical law suit on your hands. Mr. Tyrone Albert.

OIL COOLER FAILURE, CAUSING OIL TO GO INTO THE COOLANT SYSTEM AND MIX. COMPLETELY DRAINING ALL OIL FROM MY ENGINE AND LEAKING FROM AND UNKNOW SEAL IN THE COOLANT SYSTEM. AT NO TIME DID MY VEHICLE WARN ME OF THE ISSUE. NO CHECK ENGINE LIGHT, NO OVERHEATING LIGHT AND I DROVE MY VEHICLE FROM HOME TO WORK WHICH IS ABOUT 60 MILES (SALISBURY, MD TO LEWES, DE) . THIS LEFT ME STRANDED AT WORK AND UNKNOW DAMAGE TO MY VEHICLE BECAUSE OF NO "CAUTION" LIGHTS. THE LEAKING OIL COULD HAVE CAUSED AN ENGINE FIRE WITH ALL THE OIL DRAINING OUT AND INTO THE COOLANT SYSTEM AND OVER HEATING MY ENGINE.

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.

The Dashboard of the car is rising and waving due to the heat of the Sun in Louisiana. This is reflecting a shean of direct/indirect sunlight off the wrinkles into the drivers eyes. It super distracting, a safety concern and a fault in the Adhesion used in the manufacturing process! HELP!! It needs to be fixed at the manufacturers level!!
