I purchased a 2015 Jeep Cherokee trailhawk in February of 2015. It was running fine until I took it in for a recall and a software update. When accelerating from a stop or yield, the Jeep hesitates then it will lunge forward. On December 8, 2015, I took the Jeep in for a recall, there was also a software update. After that date my vehicle was never the same. Prior to December 8, 2015, I had no complaints about the transmission. We have taken the Jeep back to the dealership December 29, 2015, February 12, 2016, May 23, 2016 with our concerns being completely ignored. In June of 2016 I contacted Chrysler and was instructed to take my Jeep back to the dealership. The dealership had my Jeep for 2 days and I was told the problem was fixed. It was not! it continues to lunge forward. I no longer drive it on the highway because when I am merging into traffic, it hesitates and I have had to pull off to the shoulder. I would like to be able to enjoy the vehicle that I have invested so much into. After being told by the mechanics and the manager of the service department, that I just don't know how to drive....it is good to know, I am not the only one with this problem and hopefully it will soon be fixed

2015 Jeep Cherokee transmission: Warning light four wheel driving system unavailable service required! when driving the transmission would shift through 2nd gear and get stuck there with very high rpms, then slamming into third. (city street & highway) it accelerates when downshifting. Normal driving, no power. While driving loud whining sound from under the SUV. When stopped and in drive and turning on ac or heat, the rpms would drop below 1K and the SUV would automatically increase the RPM causing it to lurch forward. Transmission shifted randomly. The dealership we leased the Jeep from replaced/reconfigured the drivetrain control module and flash programmed the ECU. They replaced a defective transfer control motor. They checked wiring harness and called a regional technician. All of these "fixes" failed after an extended test drive. Rt 46 Chrysler, Jeep, Dodge said they now need to replace the transmission control motor. The car has been at their shop for almost a week. Chrysler corporate said they will not cover consequential damages due to defective parts under warranty. The sales manager at rt 46 Chrysler Jeep Dodge would not take our 2015 Cherokee as trade in for a new SUV because he called it a lemon. This vehicle is unpredictable and unsafe while driving. The dealership we leased the Cherokee from doesn't even want it back.

The transmission shifts super hard every time it shifts.

- Louisville, KY, USA

My vehicle jerks forward after stopping, increases speed while slowing down on a hill, feels like the transmission is going to shoot out from under the car. I feel very unsafe driving it.

- Omaha, NE, USA

While pulling out, into traffic, my tire caught some icy slush. It started to spin. As I was already on the road in traffic, I gave it more gas to go. The engine revved. I noticed the rpms had pegged around 6000+. I noticed no traction control, at least not how I have felt it in other vehicles. I finally got out in traffic. This is when my car went haywire. The dashed flashed a warning that my car was going into safe mode and would be shifting to neutral. Then there was a loud clunk and it felt like I got hit from behind. I did not, although I'm sure the person I pulled in front of would've like to have hit me, as he was blowing his horn at me and flipping me off. My car was now in neutral and couldn't go anywhere. I pulled to the side of the road. As I came to a stop my car engaged the parking brake. I was panicked and scared. I turned off my car. I called my husband. I tried to restart my car. It restarted but I could not disengage the parking brake. The check engine light came on. The traction control light came on. The brake light came on. My husband showed up and through trial and error he found out that he could only disengage the parking brake if the car was in neutral. He drove it around some and it seemed fine. I drove it to work, with all those dash lights still on. I called the dealership and got my car in. Within 2 days the dashlights had turned off and everything seemed to be normal. I took my car in and since there were no lights on at that time they couldn't diagnose anything. They told me it was a safety override and I just needed to learn to drive it. (I was livid, as I have had many problems with the transmission) a vehicle should not shut down in traffic. Luckily I was on a rural road when this happened. I couldn't imagine what could of happened if I was pulling out across 5 lanes of traffic or merging on to a busy freeway. This is unacceptable.

Transmission jerks slams in gear doesn't know what gear it should be in hesitates when stopped then goes into gear doesn't know what gear to be in on the highway takes to long to go into passing gears

- Honey Brook, PA, USA

My vehicle continuously "cluncks" when shifting between certain gears. Happens daily now and is very unsettling because there is a loss of power/acceleration when it happens. Started when shifting between 3rd and 4th but now does it from 1st to 2nd. Dealership is well aware, say there are about 2-3000 Jeep out there doing the same thing but they won't fix it because the check engine light doesn't come on and they don't know which part is broken/failing.

- Wichita, KS, USA

Transmission bucks and lurches. Slow to respond to gas when pulling out. Looks for a gear while driving in traffic. Dangerous to drive not knowing what the trans will do or not do. Took it to 2 different dealers and they claim no problems. The updates do not correct the issues. It has been in the shop & times for this ongoing problem. I'm paying for a lease and rarely drive it after 2+ years of ownership 10970 miles on it. I don't trust it for a long trip any longer.

- Germantown, MD, USA

Service light for transmission will illuminate when on the expressway. If you slow down car will jerk and make a loud clunk noise. When resuming acceleration this noise has to happen. The light goes off at times

- Chicago, IL, USA

The transmission does not automatically downshift out of 3rd gear when coming to a stop or at a brief stop resulting in loss of power at take off. Trying to accelerate from a stop while in 3rd gear results in significant delay in power. This hesitation is similar to stalling which is very dangerous when pulling into traffic. Jeep has stated that this is normal and that you must always come to a complete extended stop before the transmission will down shift. This is not feasible when a complete stop is not necessary or required like when a light changes to green when you are coming to a stop, or you are merging into traffic with a yield sign. This is an accident waiting to happen, or is already resulting in accidents that are classified as your vehicle didn't yield to right of way, even though this stall like scenario is the primary contributor.

- Lake Zurich, IL, USA

The contact owns a 2015 Jeep Cherokee. While driving 45 mph, the transmission began to shift improperly and hard shifted intermittently. Also, the steering wheel vibrated without warning. The vehicle was taken to the dealer where it was diagnosed that the transmission and the steering column needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 1,200.

- Las Vegas, NV, USA

The contact owns a 2015 Jeep Cherokee. While stationary, the vehicle would not downshift and remained in third gear instead of first or second gear. The contact stated that the vehicle seemed as if it wanted to stall. There was not enough power to the vehicle upon acceleration from third gear. The dealer replaced the PCM, but the failure recurred. The manufacturer was made aware of the failure. The failure mileage was 46,677.

- Rison, AR, USA

Vehicle is hesitating to find appropriate gear at very low to low speeds (0-20 mph). The result is the absence of smooth transition to the next higher or lower gear and frequent abrupt lunging of the vehicle in a forward direction. This seems to pose a safety concern for vehicle occupants and pedestrians in situations which involve parking and/or pedestrian right of way. This happens repeatedly and not only on date indicated below as required by this form.

- San Diego, CA, USA

Vehicle is unsafe to drive. Transmission doesn't not function properly. Dealer is unwilling to help. I have taken it in multiple times for software updates and for check ups. There are harsh shifts, wobbles, delayed reaction when gas pedal applied. Jeep has advised there is no fix. When making a turn, and gas is applied, nothing happens. Causing to sit in the middle of on coming traffic. Extremely jerky. Unsafe

- Mount Pleasant, TX, USA

On going document issues with the 9 speed automatic transmission. There is jerkiness, hesitation, stalling during acceleration from a stopped position. There is also hard shifts, lunging, and unexpected disengagement. Transmission continues in low gears wanting to shift but does not causing increased RPM's and uncertainties.

- Mcmurray, PA, USA

We purchased this vehicle as a 'certified pre-owned' and felt confident that since it was 'certified' it was in excellent condition. We have owned the vehicle since August 2016 and have had numerous issues with the transmission. We have taken it to our local Jeep dealer/shop and they said they can't find anything wrong with it. They have performed two system updates and thought that might be the issue. When taking off from a stopped position or slowed/almost stopped position the transmission has a pause. On numerous occasions we have almost gotten hit because the transmission paused. We have also had occasions when it will pause and then just kick in and take off like someone stepped all the way down on the gas pedal. Even though I have been told by the Jeep service department that this is 'normal' I feel this is anything but 'normal'. this vehicle is an accident waiting to happen and I do not feel safe driving it.

- Hughson, CA, USA

While going up a steep hill, it makes a thump/bang when shifting between 4th and 5th gear automatically. It does not happen all the time. You can actually feel a vibration through the floor boards when it happens. It also hesitates slightly when it occurs. The noise it loud enough that even if the radio is on it can me heard. My wife in the passenger seat also made comment that she heard the noise and felt the vibration. Auto transmissions are not supposed to shift like this. I was told recently that is characteristic of the vehicle to shift ruff between those gears but this is more then just ruff shifting. It also accelerates on it S own when you leave off the gas on it's own and not slow dpown lie it should

- New Oxford, PA, USA

I have a 2015 Jeep Cherokee latitude, 6 cyl. Ever since I drove it off the lot, if at a complete stop and accelerate to enter traffic there is a noticeable long pause when I gun it. Many times I have had to pull to the side to avoid getting hit. Also when accelerating on the expressway when hitting the gas, the vehicle pauses before accelerating. This also has caused near collisions with other vehicles due to the long pause before finally accelerating. I have told the dealer about the problem everytime I go there for an oil change. They have updated the computer system many times with no results on fixing the problem, they tell me that I am not the only one with this issue. The 9-speed transmission has a lot of problems I am told, and they still have yet to find a real solution. Someone is going to get killed thinking they can pull out in front of traffic only to find the vehicle has a long hesitation before accelerating. I was planning on giving this car to my son, but there is no way I would let him drive this vehicle with the above mentioned issue. The dealer has too long ignored, or are ignorant of this potential life threatening issue with acceleration problems. Other than that issue the vehicle has been decent.

- Brighton, MI, USA

Transmission trouble with only 18000 miles. Service transmission warning displayed. Initially at dealer told the update would not fix problem but then they were able to magically fix it with an update. Very concerned since multiple reports on NHTSA with similar fixes that did not work and car suddenly stopping. Service departmnent did not feel that my family's safety or the multiple complaints stating this fix did not work.

- St. Louis, MO, USA

The vehicle shut off when driving. After calling a Jeep dealer and asking if they where having any trouble like this. I also informed the dealer that the Cherokee had 36500 miles 500 over covered warranty. I was informed the work would not be covered so I took it to a local garage. Was told it needs a thermostat. Had to call a dealer after several attempts to locate the part. All the dealer said the part is on national back order. If the part is that popular to replace that you cant keep it in stock than there most be an issue. This vehicle is not safe if this part is causing the motor to shut off when driving down the road at highway speed. Their seems to be a lot of trouble with this vehicle. I hope Chrysler will not just let the issue go hoping that people just deal with it there self. Been to the garage 3 times and still have 5 years to pay for it. It is enough of a problem that I thought I would take this step.called Chrysler customer service first time was disconnected before I could type my massage. Second time was told they could put a rush on my part gee thanks.how about just make a vehicle that will not get someone killed by shutting of on the highway.
