Then about 10 miles further on the road, coming up to a stop sign the same behavior reoccurred. Car was delivered to dealer on 9-03-2015 and their service report of 9-04-2015 indicates that they flashed tcm, BCM, ipc and R40 recall.

The contact owns a 2014 Jeep Cherokee. While driving at various speeds and attempting to accelerate, the gears failed to engage and caused the vehicle to lunge forward. The vehicle was taken to the dealer. The technician stated that the vehicle was working up to specifications. The manufacturer was made aware of the failure and sent out an engineer to inspect the vehicle. The vehicle was not repaired. The failure mileage was 300.

- Oregon, OH, USA

The vehicle almost from the time of purchase exhibited transmission problems, when merging into traffic the car would lag and not engage. This was something that occurred at what appeared random times. It would jerk to the point that I thought I was rear ended. This persisted and I have taken the vehicle to two different dealerships and worked with three case managers at Jeep customer care and the issue was never resolved. This week the transmission completely went out. The car has not been safe for sometime due to situational circumstances. I have had nothing but trouble from the vehicle since purchase (new) and had had to take the vehicle in for repairs multiple times with no resolution made.

Was driving home and check transmission and motor lights came on. We pulled over stopped car and turned on and could drive home. Next day with kids in heavy traffic, car just coasted and all lights went on, kids were scared and almost hit by a truck as we pulled over to curve. Restarted car and could drive home but the transmission was jerky. Next morning took to dealer and they found all the faults I reported. They said communication problem and cleaned all leads and said if happend again they would have to contact chrystler direct. Next morning, lights came back on check transmission and pulling out of my garage, almost slammed me into a wall changing gears. Dealer confirmed problem in transmission and ordered a new one under guarantee. I am without a car for at least 3 weeks and dealer said if I had gotten the extended guarantee would have gotten reinbursed for an auto rental after 5 business days of not having car. Really concerned about safety and everyone is fortunate no fatalities yet due to a defective 9 speed transmission design. My car was fine until they did a software update to deal with transmission complains. Really supprised usa government has not recalled the transmission or allow family car owners like myself who thought this Jeep was safe with good gas milage to exchange cars or sell back. Have to wait and see if new transmission works or simply replacing one poorly designed part with hanother. Actually liked the car, just now concerned with my family safety.

Right after I purchased the vehicle brand new in August of 1914, the auto transmission jumped at 5 mph to 45 mph when shifting gears. I contacted Chrysler Jeep and the local Jeep dealer did one update on the transmission that did not solver the problem. I contacted Chrysler Jeep customer service and was told several times that they would send me another update for my vehicle in augusto of 2015 for my problem. It is now September 2, 2015 and no second transmission update has as yet arrived for my problem. The problem is still in the transmission and they have not fixed it yet. I now have other recall issues with the power liftgate but as yet no parts and the ro recall that I have not as yet had done. I want the second update for my auto transmission fixed.

- Midland, GA, USA

I bought my 2014 Jeep Cherokee brand new off of the lot on 4/25/2015. With less than 200 miles on it I noticed that the transmission would hesitate from a stop, and seem almost like the transmission would have a "lag" when I accelerated going up a slight incline and be jerky when it shifted at times. It has been in the Jeep dealership 2 times for this and is scheduled to go again on 8/31/2015. This time it is lunging after backing out of garage and going into drive. It is scary when it finally grabs the gear it actually squeals the back tires. The 1st time on 6/3/15 the dealership performed a software update for PCM, & tcm. 2nd time 6/23/15 the dealer did a tcm software update 181905bk.3 02-19-05-95.4. this time I rode around with the mechanic to 1/2 hr after he did the update. Most of the time these issues happen at lower speeds, but now I have noticed it happening on the freeway too. I do not feel safe driving this car anymore.

I have previously submitted a complaint but left out this incident. I was traveling on a highway at about 30 mph. The vehicle all of a sudden would not accelerate some icons appeared on the dash. I pulled over and waited a few minutes. I started the vehicle and resumed my travel. After starting and stopping a few times the icons disappeared.

I have had three recalls on this model. One for a transmission recalibration, one for a shock absorber, and one for an airbag. There is one outstanding for the liftgate but the parts are not available.---I stopped at a stop sign on April 1, 2015 and turned right. The vehicle wouldn't accelerate and several icons appeared on the dash. I turned the vehicle off and on several times and shifted it in and out of gear several times. It finally went into gear and moved forward but was locked into about fourth gear. I travelled 15 miles to the nearest chysler/Jeep dealership for service. The dealership recalibrated the transmission. On May 29 and May 30 the parking brake and engine icon appeared on the dash and when I shifted the vehicle into gear it would not go out of gear because the parking brake was on. I pressed and released the parking gear several times and then it would go into park and I could shut the engine off. This happened several times in my garage. I called Chrysler/Jeep on June 5th at about 40,000 miles and had the vehicle towed to the closest dealership (where I had taken it before). The dealership replaced the transmission module. Two different times since the module was replaced there have been icons appear on the dash. I turn the vehicle off and on and the icons eventually disappear. The transmission is slow to engage after backing up and sluggish to shift when slowing to a stop and then moving forward.

August 24, 2015: This can be considered an update to report tracking # 10758562. We were taking our 2014 Jeep Cherokee latitude to the a dealership for service, due to the events reported in #10758562. We were on I-95 when the engine light/service transmission message illuminated. Highway speed and performance were not affected, but when we left the highway and were in a stretch of road with traffic lights, acceleration was very sluggish, as in the prior incidents reported in #10758562. No gas had been added since Friday morning (8/21), and the Jeep was not driven on Saturday or Sunday. It had been driven 2-3 miles on local streets on the morning of 8/24, without incident. The 8/24 incident means that on the last 4 days the Jeep has been driven, there has been an incident each day, involving transmission freeze and/or loss of acceleration.

With our 2014 Jeep Cherokee 4cyl. We were close to a horrible collision. We were merging onto a major highway when the SUV lost power when accelerating and the transmission disengaged. We were nearly sideswiped by a semi!!!!! when giving the SUV gas, it downshifted to accelerate and then all of a sudden disengaged and the SUV felt like it halted forward slowing down to 15mph. It seemed as if the engine and transmission were not communicating correctly. If the gas pedal was softly pressed the SUV would accelerate, however, if the gas pedal was pressed down further, the transmission was just gone! this continued to happen until the car was power cycled off. This is a major safety concern. Brought it to the dealership and they couldn't find anything wrong. I am so scared to drive this SUV now. Please investigate and have a safety update soon!!!!

Text of letter sent to Jeep/Chrysler on 08/21/2015. Earlier this year I began experiencing poor performance from the transmission in the Jeep I purchased in late December. Shortly after this began I received a recall notice regarding the software governing the transmission. After having this, and an airbag recall, addressed the issue got worse. Again taking it in, the dealer confirmed the existence of the poor performance. However, they had no solution stating that it was a software issue, Chrysler is aware of the problem but has no fix. This transmission defect is causing driving problems and unsafe conditions. I can not rely on the vehicle to accelerate at any time. Even driving with extreme caution, I have been left in several unsafe situations when merging on the freeway or entering traffic. I have now needed to avoid left turns across traffic. I like the car in general and I am asked about it often. Unfortunately, I am beyond disappointed with this problem and have stated this to everyone who asks about the vehicle. I had not bought a brand new car for several years and only did so with the belief that I would be avoiding car problems. I would like to know how Chrysler intends to resolve this issue and more importantly when. I have copied this letter to the Washington state consumer protection bureau and the nthsa.

I was exiting a highway and had slowed down to a near stop. When I tried to accelerate, the car wouldn't move and then lunged forward. I nearly crashed into the car in front of me. Issues with the transmission of this vehicle have persisted since I first picked the car up in March of 2014. It has been back to the dealership eight times, with five updates being performed, no to avail. The vehicle is unsafe.

- Pelham, NY, USA

While driving an approx. 10 hour trip from Colorado to Texas vehicle began experiencing problems. Halfway into the trip the check engine light came on after stopping to get fuel. Few miles later the transmission notification appeared and the shifter started blinking while in drive. Came to a stop at a stop sign and the vehicle had problems downshifting in order to brake. Braking took longer than usual. Car rolled backwards when taking off from that same stop sign. Lower gears had a hard time shifting. Rpms unusually high at speeds over 60. Car accelerated on its own multiple times. Car would not allow any dash functions when the transmission temp would go above 200. Pulled over several times to let the engine cool. Restarted car after auto braking feature prevented driving in reverse. Car had trouble driving uphill. No word from dealership but this is the 2nd time in 4 months car has been in the shop. First time was a check engine light having to do with the oil components. I am truly concerned for the safety of my children. When will this problem be taken seriously" when someone dies?"

- Rome City, IN, USA

The car did not accelerate when peddle was pushed (in heavy traffic) then jumped suddenly to accelerate into oncoming traffic. This vehicle has had complete valve body failure in less than 3,000 miles and numerous updates to the computer because of uneven shifting and acceleration. The latest update seemed to work better for a few weeks and now is worse than previously. The Chrysler dealer (ron carter alvin Texas) refuses to return my calls for service or to set a service date.

- League City, TX, USA

Love my Jeep except for various shifting and lurching problems.occasionally lurches when putting vehicle in gear forward or backward.latest problem was on accelerating or lack there of.I was at a light turning left.I realized a car coming at me was going pretty fast so I pressed hard on accelerator, RPM's shot up engine sound raced but car only crept forward then approx 1 second later it caught and I made the turn in time, barely.the transmission has gone from being a nuisance to very dangerous. Could have been disastrous consequences.
