Differential Unit problems of the 2014 Jeep Cherokee

Power train:automatic transmission | power train:driveline:differential unit continues to experience movement in the power transfer unit (ptu) between the differential input splines and the transmission output shaft and has caused input spline teeth to wear off, leading to a loss of engagement between the transmission and the differential inside the ptu. If there was a recall performed on this vehicle, it was either too late, or ineffective. Requires a new ptu.

2014 Jeep - Cherokee trailhawk - differential malfunctioning. There seem to be widespread issue with the differential malfunctioning. Took the car for service and the mechanic found that the rear differential is leaking fluid all over. They checked the differential fluid level and noted excessive amount of metal present in diff. And fluid that leaked. This makes the car very dangerous to drive because the wheels can lock anytime. They called the dealer for parts and the dealer confirmed that they have been seeing excessive amounts of cars with such issues. There are shortage of the part nationwide. More than 150 cases reported to the dealer in santa cruz. The dealer is expecting to receive 50 parts after 45 days leaving more than 100 vehicles with no solution. The mechanic was in shock to see the excessive damage and deemed the car as a ticking time bomb. . Read more...

The rear differential/power module assembly made from cast iron split along a casting fault and lost almost all of its fluid. I only discovered this when I noticed a large puddle of fluid on my driveway and the service 4wd light cane on when I started the vehicle. I had the vehicle towed to my local service station and they had never seen anything like this before, but had located similar stories online with even worse pictures same vehicle year and mileage (101,000 mi). Suggested I call Jeep dealer and Chrysler. I called both and they would not contribute anything toward the repair. This vehicle was never in an accident or abused in any way. I feel this is an obvious manufacturing defect and should have been replaced under a recall. If this had occurred at high speed I also feel it could have been quite dangerous.

Under recall w47 a software update was done at dealer asked service adviser if this was just a temporary fix until parts were available and was informed that the update to computer was all that was being done even thou under NHTSA recall report 20v-343 it states that differential input splines and transmission output shaft may result in the teeth of the input splines wearing off I feel these parts should be replaced under recall w47 not just a reprogramming of dtcm drive train control module and epb electric park brake software especially since according to report a more robust differential input splines are being used in later models please look into this recall and replace parts that are needed to make vehicle safe to operate again.

Vehicle died on main road just over 30000 miles said it was the uconnect . Turns out after a month and a half of them having it they had to replace the transmission. Ruff shifts over accelerates. Suspension right after that. Died on the highway going 55!!! semi truck almost killed my family. Took dealership over a week to even look at it said it was a sensor. Died again 4wheel drive light came on. Said it was a module. Now they say its the rear differential and its on back order and can take up to 2 weeks. This vehicle is not safe. Transmission constantly goes out. Afraid my family will get hurt.

Tl- the contact owns a 2014 Jeep Cherokee. The contact stated that while driving at various speeds in 2nd and 3rd gears the engine would rev very high and the vehicle would jerk and hesitate. The vehicle was taken to the local dealer crown Chrysler/Dodge located at 2120 chatman rd. Chattanooga TN. Who diagnosed that the transmission was faulty and need to be reprogrammed. After reprogramming the transmission the failures continued to occur. Also, after refueling the vehcile would stall and shut off. The cause of the failure was not determined. Upon inspection it was discovered that gear fluid had leaked from the rear driver side differential axle bearings. The cause of the failure was not determined. The manufacturer was notified of the failure but no assistance was offered. The failure mileage was 30,000. Jft.

There have been several times while driving the Jeep that the same transmission problem occurred. Twice I was approaching a stop sign in a residential area, once I was coasting down a hill on a city street, once I was slowly accelerating in rush hour traffic on a major interstate, and another time I was accelerating from being stopped at a red light on a city street. The service transmission message along with several lights indicated a transmission problem. I have a picture attached. The dealership I took it took pulled a shift differential code off the vehicle. The problem is intermittent and does not happen every time it is driven. However, this is a serious safety concern to me because the vehicle is not driveable until I turn off the engine, open the door and restart the engine several times until only the mil light is on. This is an accident waiting to happen especially with me driving 29 miles each way through 2 tunnels during rush hour. It is unsafe for me to be broken down in rush hour traffic on an interstate. I fear that I will not be in the right lane like I was previously to be able to try to pull off the road. I fear I will be driving 55 miles in a tunnel and cars not stopping behind me. I fear that I will be causing an accident trying to open the door to reset the engine. No one should have to live with this fear that you are not safe with driving to and from work.

Upon acceleration from full stop my Jeep made a loud clunking sound from the rear of the vehicle which felt like something was jammed in the axle. Had the vehicle towed to courtesy motors in danville, IL and they replaced the rear differential. They refused to provide a loaner although it took 4 days to repair. When I picked it up on 5/26 the same issue was still present. I was told to "baby it" on my 4 hour drive home and take it to my dealer. My dealer identified the 2nd issue as the power transfer unit which is being replaced as well. My dealer gave me a loaner but 13 days in the shop to replace such items on a vehicle less than a year old is seriously concerning!.
