Transmission has been a problem since purchase. Numerous repairs done without success and finally they replaced the entire transmission. Still had problems. Car has only 93,000 miles on it and now the Power transfer Unit is failing. I understand that it was replaced when they put in the new transmission. Noticed a large number of complaints about PTU on line. Why hasn-??t this been recalled? It was in Canada.

A couple of issues are occurring and this is all over the internet as well and I have decided to file a complaint as this vehicle should be recalled. Most recently the car shuts off while driving and need to coast into the breakdown lane. The transmission shifts very rough as well as this model in addition the engine seems to eat the oil as well. I purchased the vehicle brand new and have consistently gotten oil changes, but a year ago when I brought this vehicle in the dealer advised I had no oil, but I got oil changes every 4-5K miles. I should not need to be pouring oil into the car. This is well known issue all over the internet with this engine. What happens is the car will shut off randomly when driving as a fail sale. In addition most recently the will shut off and there is oil in the engine, but it starts jerking the engine as if it is trying to change gears and then the car loses the ability to accelerate and actually deaccelerate. I have to pull over and the car will not drive. I have to turn the car off and let it sit for a minute or two and then turn it back on. This is highly dangerous as someone can smash into the back of the car while i am driving since the car loses power. I have brought the car in numerous times to the shop over the years due to the transmission/engine failures. This engine/transmission needs to be recalled as these cars should not be on the road. Most recently I brought it back to the dealer and they advised they could not replicate the problem. It is back in the shop today as well 5/31/23 as the incident occurred again 3 days after. I have some video I can email as well.

When driving the Jeep and within a speed between 35 and 45 mph at a steady rate, if you accelerate or decelerate, the transmission slams really hard into the next gear or downshifts hard into the next gear which leads to the snapping of your neck as if it was a whiplash affect. We have brought this vehicle in many time for several years and without a code that gets generated and recorded on the Jeeps computer of the issue. We do not know where to turn next as the dealers that had evaluate the jeep viewed and the technicians experienced the symptom that we explained, but they were not able to provide a resolution Under the warranty process without an error code. Having people in the Jeep and when it downshift or upshift the transmission slams into gear have been getting startled as if someone hit us from behind and we have had neck pains from this result. We are very concerned that if the downshifting or up shifting that slams into gear may result in a transmission failure while we are on the road and will have no control of our vehicle and could lead to a major accident as we could be stuck in the middle of a road with heavy traffic.

Jeep transmission jerks, doesn't shift when its supposed to, and when I give it regular pressure gas, and I drive slow, it will not shift and then suddenly shift causing a jerk. I never can depend on the vehicle and even don't make left hand turns unless there is a traffic light because I'm afraid the Jeep won't pull out in time and I'll get hit by another car.

Vehicle emits a loud thug/clunk when driving at lower speeds and gears shifting. No other Jeeps I have owned have done this. They will not look into whether or not it is the Transmission or PTU issue. This is a known issue for 2014-2015 Jeep Cherokees. There needs to be a recall. Vehicle has less than 90k miles. Have been advised by Jeep dealership that "jeeps are supposed to do that".

I currently have 87000 miles. I have a service 4 wheel drive 4 wheel drive unavailable light. I had this light scanned and it turns out that my ptu is defective and malfunctioning. I recently did research on this and found out there was a recall on this issue. The recall number is w47 campaign number 20V343. There-??s another recall number w48 campaign number 20E037. These are related to the ptu in models 2014 through 2017. Not sure why my vehicle was not included in this recall. From what I was reading this defective part can cause serious safety issues. I never received a recall notice for this even though my vehicle is a 2015 which apparently has this issue that jeep know about. The part alone for the ptu is over 1000 dollars and I no longer have warranty.

PTU making noises about to go out

- Kirbyville, TX, USA

Power transfer unit failure. Very common and very expensive fix on 2015 Cherokee-??s. This caused my vehicle to lose all power on the highway almost resulting in me being rear ended. With what seemed like divine intervention I made it safely to the shoulder with almost no steering capabilities and zero power.

When I was driving the gear shift into Netural, all lights on gear shift were lit up red (Park, Reverse, Netural, Drive). The message said -??Press brake, Put car in P, Select Gear-??. This is so scary because it has happened twice to me. When I took to Midas as soon as it happen, since they were open. The ran a code that read U0001, and read that this is a power train issue. And informed me to take to the dealership because it should be covered for the recall that-??s in these models. While driving on highways I have had to put car on side of road to keep from a crash. This is a real hazard and safety concern.

Dear NHTSA, Subject: Manufacturing transmission malfunction - TRAFFIC SAFETY Your attention is kindly requested. I own a 2015 Jeep Cherokee, diesel 2.0L, 170hp, 4x4, 9-speed [XXX] automatic. My car-??s VIN is: [XXX]. On 21800km for the first time, while I was driving on the highway, a "service transmission" message came up on the dial, and after a while, the engine stopped moving the wheels and went into neutral. I stepped on the gas but it wouldn't move the wheels. If I was driving in the left lane, the only thing sure is that an accident would have occurred. The car's problem has to do with the 9-speed automatic gearbox. Immediately, I informed the official dealer of Jeep in Greece (Auto One).They told me that there was an official recall (S55) for this model. The car was repaired by the dealer on May 15thof 2017.However, after 500 km the problem was shown again and again. Every time the problem was shown I visited the specific dealer, but he didn't admit that the same problem might happen again. Because of this, I was forced to visit another service dealer, December 28th 2018 (24.300km), who confirmed in writing that the problem was unsolved. He advised me to go to the first dealer (Auto One). So, I went again to Auto One. They informed me that according to official guidelines from FCA/Jeep, any further repair concerning this problem should be paid for by the car owner without any guarantee. I found their attitude very offensive, so I preferred not to pay such a huge amount of money for something I was not responsible for. As I didn't use my car every day and the problem was not permanent I tried to find another way to solve the problem. Lately, the problem is shown very often, while many days the car does not start at all. The car today has only 41.000 kilometers. I found that there are many complaints from different areas of the world about the same issue, around 800.000 cars. Therefore Jeep after many complaints has INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C

I was making a left turn onto the southbound roadway which which consists of six Lanes. I was getting up to approximately 35 mph when the parking symbol light came on and the screen was showing service parking brake and service transmission. I was still in Drive when the car started coasting and when I stepped on the gas, all it did was revved. I had to Coast into the left turning lane and came to a stop as I tried to put it in park I could hear a whirring noise coming from under the dash as if the parking break button was pressed. I could not get it out of Drive and I tried putting it in neutral then back to drive then into neutral but could not get the car to move. Finally was able to get it into park and I shut the car off. After about 10 minutes I started the car up and the dash showed nothing I put it into drive and it kicked into gear and as I accelerated it was feeling like I couldn't get out of second. Then the brake light came on the p in a circle with an exclamation mark came on, ABS light came on, skid light came on., check engine light came on, and the screen flashing back and forth between service parking brake and service transmission. I was able to make it 2 miles to work at very slow speed and put it in park and turned it off. There was more rollback than normal when put in park so I put a chuck under the wheel so it wouldn't roll. Approximately an hour later I took it up to Tire Plus to see what was wrong. Upon picking it up they told me that I had to take to a dealer. The following codes are; u0418, u04828, u1412, p1720, u0420, uc003, u0415. When I went to pick the car up some hours later it started right up like normal and halfway home which is approximately 3miles, everything lit up again this time the engine sounded rough and again I had to Coast to the right side of the road shut it off wait 10 minutes, start it up and I was able to get it home, where it's been since. I'm very concerned for my safety. From Reading, alot of others are as well.

After a Jeep Dealership performed a recall, the Service Shifter indicator came on. The indicator blocks important information on the dash screen such as speed and other vehicle info. There was no issue or light that appeared prior to the dealer getting their hands on to the car.
