Vehicle shows parking brake on when I enter. It has never done this before. Drove down street to stop and put car in park, parking park comes on automatically? This started today Sept. 7, 2021. On interstate going 70 mph vehicle bucked when I accelerated. On same trip, not in cruise control vehicle RPM's went up and down by itself. Proceeded to slow lane to stop. Once stopped I put car in park (no parking brake showed up) pushed on gas pedal to watch RPM's and transmission took its time coming back down. Left side of road hitting gas got to 45mph and vehicle bucked. Made load noise and bucked. The "bucking started on my 1st trip out of town, all loaded up for a work event. Going 65 mph down to exit ramp, accelerate and it bucked. Kids looked at me and said, "Mom this better not have a transmission problem like the old car." (GMC Envoy 4x4 bought new trans & then engine needed to be replaced, but went car shopping) Took vehicle back to CarMax and they said the didn't notice a thing.They said you know the wheels make a lot of noise because they are big. Also, told me not to accelerate so fast! What? I bought this vehicle on Mother's Day 2019. Went to Maryland to purchase it. Found out later that Maryland doesn't do inspections every year. Too it to my local CarMax and they gave it new brakes. I have an appointment with a Jeep certified dealer mechanics department on Sept. 24, 2021. I will follow up with another note. I hope the transmission gets replaced because the problems I mentioned are on a forum that Jeep experts monitor and comment on as I see their icon/symbol. Thank you

Jeep Trailhawk RPM's dial up and down while driving with no advanced speed. Vehicle does not move from a stop position without "kicking" or "bumping" you forward. While on interstate, going posted speed without cruise control but maintaining speed, vehicle "bucks." While driving in neighborhoods car has difficulty going from 25mph to 35mph. From stop sign to accelerate, vehicle does't move, or goes slowly with foot pressed down on gas pedal, then "bucks/bumps." Coming off from the interstate to an exit whilst vehicle is slowing down around exit curve then accelerate back up, vehicle "booms', loud "pop." The RPM's can not stay still on vehicle. When slowly moving traffic it does this too. If inching forward, it does't want to. At some points it accelerates forward when I did not want to go.

When my service 4wheel drive light came on I took my 2015 Jeep Cherokee in for service. I was told that my PTU needs to be replaced. I read online that there was a recall on these. I am wondering why my Jeep is not covered by the recall. Clearly I have a faulty part with only 72,000 on my vehicle

2015 JEEP CHEROKEE TH with 75xxx miles. Currently covered under Mopar extended warranty for used vehicles. When driving this vehicle you experience a hard shift from a stop/ yield slow down, this so violent that it will spin the tired and push you back into your seat. There is also a large amount a lag that happens, resulting in almost a loss of power to the wheels. This has put me in unsafe situations where I needed the vehicle to move in order to avoid a other drivers and hazard. This is a known issue as there are a large about of others reporting here. I have had this Jeep in the shop under warranty work 4 times now, first they said a update of the ppm/tcm would fix the issue, then a new valve body was going to fix it. however none of these have helped. I can only assume they will attempt to put a new transmission in on my upcoming service appointment. However I am not confident this will be the final solution. As previously stated this a a wide spread known issue with many reports. However there are still so many dealing with this issue that Jeep and Mopar should step up and fix, for free. No one has been injured or killed due to this yet but I am sure one day that will change unless there is a definitive fix for the 2015 JEEP CHEROKEE transmission hard shift.

When you are stopped at a light waiting to go, the 2015 Cherokee Trailhawk delays going. Sometimes when it is in second gear it stays there too long before shifting.Sometimes the 2015 Cherokee Trailhawk jerks into gear as it feel like someone has run into the back of the truck. Today following start up, putting the 2015 Cherokee Trailhawk into reverse, no power at all. The dash lit up stating, " 4 Wheel drive system temporarily unavailable, Service transmission, Service parking brake", the MIL light on the cluster panel is lit, the drive light is blinking on the dash and on the gearshift. I was in fear for my safety as I had to restart the 2015 Cherokee Trailhawk 3 times to travel 11 miles. I drove with my emergency flashers and had to pull off to the side of the road to restart the truck.The 2015 Cherokee Trailhawk is also jerking into gear when I put it in reverse. There was a recall for the Power Transfer Unit that involved a software update that was completed 1/2020. Following the software update, the truck rand smooth for approximately 8 months, then the transmission started to slip again. Although this problem was never resolved.I recently received a notice from Jeep that the Power Transfer Unit warranty has been extended to 8 years /150,000 miles. This 2015 Cherokee Trailhawk only has 48,000 miles on it. I have a pending service appointment for 8/30/2021. I am going to have the dealer replace that part hoping it will improve the safety of the vehicle.

While driving on the freeway, with cruise control set at approximately 69 MPH, my 2015 Jeep Cherokee warning system luminates the Service Transmission and Check Engine lights. Traveling approximately another 2 miles to the nearest exit off the freeway, I slow the Jeep down as I exit the freeway ramp. The Jeep has very little, if any, power to make it through the traffic light crossing into the intersection. With little power other vehicles narrowly miss me from being run into because I am not able to move out of lane(s). This is the second time this has happened. Most recently I received my Jeep back from being serviced for this event 3 days ago and 62 miles. They dealership service department was not able to identify or replica the issue. This service transmission failure is a hazard and it could cause serious injury or property damage because there is no warning and the vehicle losses power not allowing the vehicle to be driven out of the way from traffic.

When I accelerate from a stop or slow rate of speed my car does not accelerate immediately. It is as if the car temporarily goes into neutral. This has caused a few near misses as I have started out into traffic and not been able to fully get out of other cars way. Several times cars have had to break hard or swerve to avoid crashing into my car.

Service shifter warning message displayed and all indicator lights are lit at shifter. Transmission would not shift out of current gear. Problem reset after turning off vehicle. Has now happened 2 other times. All within the last 10 days.

When I purchased the vehicle in 2015 with 5000 miles the check engine light was on and the transmission was replaced and I have always had issues when accelerating and it shifting loudly and more recently check engine light turns off and on.

I have had my vehicle checked out several times over the malfunction of the stop and start system. Several times it has been worked on and looked at. Once they claimed they replaced a part under the hood in Richmond, kentucky. This issue has been going on for over two years. It had been cutting off and not starting back. Now its advanced into a jerking from a hesitation to switch between gears. The malfunction light keeps coming back on. And sometimes it has to be restarted several times just to reset it. It was on 7/30/2021 when someone besides me noticed this issue. But its been doing me this way for last three months.

2015 Jeep Cherokee Limited. While driving the vehicle, lost power abruptly and without warning in traffic on 5 occasions between May 2021 and July. Car towed and taken to dealership each time with repair notations indicating short in PDC causing fuse for ignition coils to blow. That was replaced. An additional note when the car failed again indicated an internal short in PCM which was replaced. I've spent thousands of dollars, not to mention the safety issue of stalling in traffic. The last time, I was on a very busy freeway and didn't have enough power to fully move to the shoulder. I counted about 3 near misses with cars about to hit me. I don't have every *Invoice* as they didn't return them all to me but will upload what I do have. This is a serious issue and I'm not getting any resolution with the dealership.

Service Shifter lights up on the instrument panel as well as the check engine also stop/start not ready. 4x4 not available exhilarates and UN exhilarates all by its own. Shifts hard and jumps hard when I take off at a stop light don't wanna come out of park unless I take my finger and flip up a plastic thing down inside the shifting housing. And the key fobe won't come out of the key switch. No it hasn't been in a crash yet but it's one looking for a place to happen if jeep don't have a recall. Yes my jeep has been confirmed by the Dodge dealership in Lexington Kentucky. They say that it needs a new shifter put in it I'm taking it to the dealership this coming Thursday

My Jeep Year, Model, and Make have a recall out for the PTU system (within the last year). When I checked my VIN number on here it said My Jeep was not part of the recall. I believe the recall should be extended outside its current limits. Just last week I had to take my Jeep in because my PTU went bad and could have potentially been dangerous if I had not taken it in (loss of power to transmission etc.). On top of that, since according to NHTSA (really FCA), my jeep isn't affected by the recall but clearly it is. So I have to pay to get it replaced out of pocket for a defective unit!

While driving home from work. The rear of my vehicle made a sudden shifting forward / jarring effect. Soon after that a notification came up saying "4WD unavailable and a ding lighting saying to service 4WD. Then all went away. My boyfriend called dealership and explained to our service advisor @ New Carlisle CDJR dealer the situation and told us to bring it in today. While driving there the 4WD indicator to service came back on and that 4WD was unavailable again. But at the dealer he could not pull it up on computer. After reminding him of the jarring effect, he decided to test drive it. As soon as a pulled out he knew something was wrong. They put it up on a lift and found the rear differential housing was CRACKED all the way around. I was lucky to be able to get it there without incident! I wonder how many other jeeps are getting ready to explode the rear end like mine and others I have read about! Hopefully FCA will release a recall on this life threatening issue that could cause a fatality!

My Jeep dashboard goes black, the vehicle stops in the middle of traffic. When I start the vehicle back up and shift it into drive it make a sound like I got rear ended. The transmission light comes on and the vehicle will only go about 20 mph. The check engine lights stays on. This has happened numerous times. The dealership kept the vehicle for 2 weeks, gave it back to me and stated they could not find anything wrong with it.

While driving my jeep forward or in reverse my jeep launches forward very hard. I have to press on the brake abruptly so that I don't hit anything. Also when accelerating my speedometer shows the numbers increasing but my wheels are barely moving then it kicks forward abruptly. When turning or going over bumps I feel a pop in the steering column and sometimes the dashboard icon with the vehicle & squiggly lines under it appears. I told my dealership but the mechanic just said there is nothing wrong with it even though I know there is.

I have to have the PTU replaced because it went. It-??s not even 6 years old and there-??s been a recall on the PTU for my make and model and year, yet they-??re saying not my vehicle. It-??s costing thousands of dollars.

Driving 70 miles an hour down highway my cars transmission light came on. Lost power to car. Pulled over and restarted car. Drove to side road where again lost all power. Had to sit in a tight blind curve to restart car. With my child in the car. This car is not old and should not have this issue. There are numerous other complaints about the same issue on 2014 and 2015 model. It is actually stated that 2015 has more complaints. And yet, jeep has done nothing to fix it.
