Nine speed automatic transmission. This is a safety issue. The transmission in the lower range of gears searches for the proper speed gear and when it finds one, it jumps into gear causing the vehicle to lurch and at times causes the vehicle to over accelerate. At higher speeds, the transmission will drop into a gear with a heavy thump which shakes the whole vehicle. The really serious problem is with the transmission when using cruise control. Just last week, I had the cruise control set at 55 mph and when on a downhill portion of roadway, the transmission suddenly went into a higher gear and the vehicle began a rapid acceleration. Before I could hit the brake to disengage the cruise control, the vehicle was traveling at well over 60mph. I have had the vehicle in four times to the dealer and they only do computer updates and can find nothing wrong with the transmission. When I call Jeep to complain, they send me back to the same dealer and nothing gets done. I think that this is a great safety issue and I feel that this vehicle will get me killed. I am a retired police officer who has driven hundreds of thousands of miles in a wide variety of vehicles having automatic transmissions and this is by far and away the worst one I have even used. Final note, the computer updates installed by the dealer has not improved the transmission and has decreased my overall gas mileage by 2 mpg. Kind of throws off the epa estimates, doesn't it.

While driving the transmission shifts unexpectedly and hard when accelerating and decelerating. It shifted so hard the other day that I though someone had hit me! the shifting at slow speeds and stop and go traffic is also rough causing jolts and rough handling. I feel unsafe driving this SUV, but do not have any other mode of transportation. Additionally, while traveling at 55-60 mph with cruise control on or off, the transmission does not leave 6th gear. It's a 9 speed transmission and despite trying different speeds it does not use anything beyond 6th gear.

At times, the transmission would shift so hard that it felt like I had been hit from the rear. They had an alert about a computer problem. As I drove home, it did it again. I took it to a different dealer to see if they would have any luck. It seemed to fix the problem for a while. The hard shifting incidents were greatly reduced. Then while driving home from highland, I noticed some hesitation in the shifting. A few blocks from my house, the engine light turned on and an alert to service the transmission came on. Just before I pulled on to my street I felt and heard three loud bangs that again made the car jerk like it had been hit from the rear. As I took off from a stop, it felt like the transmission was slipping. It just wouldn't go. I pulled into the driveway and when I got out of the car, I noticed an odor like burnt oil. I called royal gate and was told to bring it in. Trip number 4 for the transmission. No problems on the way there. A week later, I got my car back. Again, I was told that it was a computer problem. I got home and when I was backing into the driveway, I heard and felt another bang. I called royal gate again. I was told that they are having problems with the nine speed transmission. Then while on my way back from an appointment, there was more slipping. On 10-01-16, I picked up my car for the sixth time. They couldn't find anything wrong with it. I asked to speak with the store manager. While waiting, one of the sales people asked me what I needed. I told him that I was picking up my Jeep Cherokee for the sixth time. He laughed and said, 'transmission?' the manager was too busy to talk to me. He was in the middle of a deal. The last time that I brought the car in, two of the service people witnessed all of the problems that I brought it in for. Now all of a sudden, no one can find the problem.

Transmission problems for almost a year now, truck violently jerks forward on acceleration mostly from a dead stop but sometimes in motion and on deceleration has almost caused many front and rear accidents. Recently on my way home from New Jersey the check engine light came on indicating service transmission the vehicle lost power while I was on the parkway almost caused an accident. I pulled over and turned off the vehicle then restarted the check engine light was still on, but I regained power to drive. That lasted a minute or two then the same thing happened. Truck lost power was in a fail safe mode barely drove above 30 or 40mph. What a long, unsafe trip home to say the least. I've had nothing but problems with this truck and have numerous complaints and repairs at the dealership. Now it's apart of this recall and no parts are available. The dealership says this problem is the recall, but they can't fix it yet. I've been without my truck for almost 2 weeks this is awful and I'm frustrated and fed-up with this vehicle. I want out of this lease asap. And ps they put me in a Dodge dart loaner care are you kidding me I drive a truck for a reason!

I was driving home from work 9/20/2016. My service transmission light came on and I lost power in my gas pedal. Would not go. I pulled over and put it in park. Put it back in drive and it was fine for a few more miles then did it again. I drove it straight to the mechanic. The computer said it was the throttle control module. He reset it and updated it. I got it back last night. I was driving to work today nad it was fine until I got on the interstate and it did it again, light came on and my car immediately slowed down. This is not safe at all. I have read many many complaints about this issue and I believe Jeep should be responsible for this. I will be trading this vehicle as soon as possible

2 problems. First. The following malfunction later caused an accident, detailed below. When driving on the highway, the cruise control would disengage, speed would drop and the steering wheel would jerk violently side to side for a moment, startling us and possibly forcing us into another lane. We thought the jerking may be due to strong winds but wanted to get the cruise control checked. This happened a couple more times in the 2H 30M drive before ultimately ending in an accident. That same trip, nearing our destination, while turning left on a single-lane off-ramp connecting the current highway to a perpendicular highway, it happened again. Unlike the previous instances where there were no obstacles around, this time our car violently ricochet against both sides of guard rails. Visually, the body was barely damaged but the tires and the inner assembly were too damaged to drive. Second. These symptoms precede the one written of above that caused the accident. When coming close to stopping, the car would jerk forward. When accelerating from zero, the car would pause and suddenly jerk forward.a

I was driving down the freeway when my service transmission came on and my vehicle instantly lost power and started jerking and grinding. Due to being on the freeway I almost got into a wreck with both of my kids in the car. I am not happy with this due to the dealer not having any parts available to fix it. I drive 40 mins to work and back and I now do not have a safe car to drive. Very disappointed wih this car and I want something done asap. I will not be associated with Jeep anymore. If something would of happened today I would definitely file a lawsuit.

- Seattle, WA, USA

The transmission on this vehicle, Cherokee trailhawk with 13K miles is very dangerous. Like others, I have been to multiple dealers numerous times for transmission software updates which seem to fix the problem but the problem seems to be relearned by the computer and comes back worse than before. Now there is a transaxle issue where all power can be lost while driving. This vehicle's transmission is bad enough with the constant lag, jerking and hesitation but now this unrepairable transaxle issue is making it very hard for me to even want to drive this incredibly unsafe vehicle. Dealers say 9 speed transmission just work this way but this is the worst shifting, most dangerous vehicle I have ever driven. I am very disappointed in this Jeep product and worry about anyone driving my vehicle.
