Check engine light came on. Took to the dealer and transmission needed to be replaced. New transmission isn't any better than the old one. Didn't like the old transmission from week one.

Purchased a brand new 2015 Jeep Cherokee Friday August 28th. On August 30th with less than 300 miles on it my Jeep Cherokee's transmission seemed to fail going about 60 miles an hour on the highway the transmission abruptly slipped causing the vehicles rpms to spike near 4000 RPM. Along with an abrupt loss of speed. Transmission service light immediately illuminated. After exiting the highway and coming to a stop the transmission was making a horrible banging noise while trying to shift into first gear. I will be going to a dealership tomorrow to have it fixed since it is a Sunday. Only 300 miles on the vehicle! I'm scared to drive it.

The powertrain is frequently unresponsive and there is often a significant lag time between pressing the accelerator and receiving any response from the powertrain when trying to accelerate from a full stop. Sometimes the vehicle responds immediately but other times it feels as if it can take a full second or more for the vehicle to respond. While this is not a big issue when accelerating from a stop light, this has become a significant issue when making a left turn across oncoming traffic because the vehicle cannot be counted on to respond and begin accelerating in a timely manner. The transmission has been replaced under warranty and the transmission/powertrain software module has been "re-flashed" under recall but neither repair has fixed the responsiveness issue.

I bought the car mid October 2014 and began noticing it did not shift properly - would "hang up" in lower gear when it should shift. Took it to the dealership (mileage aprx 2,500) which said it was "throwing codes" so they adjusted the transmission. This still did not correct the issue so I took it back and they said they could find nothing wrong but did make a minor adjustment but the problem continued to get worse. At aprx 5,700 miles they put a new transmission in the vehicle (probably May 2015). In June, the vehicle began to falter when it was trying to shift and while driving (happens at any speed) and, while sitting at stop lights it would surge forward with my foot on the brake. The dealership has adjusted it twice since then. The dealership has offered to sell the car at auction for me and Jeep wants to send in a "star repair" team to work on the vehicle some more. I have had this car already worked on 5 times and no one has a clue of what to do to repair it. It is dangerous in that when you pull into traffic and the car falters/stalls out it can create a potential wreck or when it the engine surges on its own a risk of running into something exists. I don't think selling it at auction just to pass the problem on to someone else or "hanging parts" on it in hopes they can fix the problem is the answer. The car now has 10,600 miles on it; has not been abused and still does not run properly or safely. I think this vehicle is a lemon and both Jeep and the dealership do not want to take responsibility for a faulty product that is dangerous to drive

Vehicle purchased end of August, noticed hard shifting and RPM surge almost immediately. Software update in December, by the end of Feb. Vehicle was going into what the dealer termed as limp mode, service engine and trans. Indicators loss of power, parking brake comes on etc. Transmission replaced in March at 5000 miles. Since then the vehicle has had several software updates to no avail. Dealer currently has had vehicle for 10 days to replace valve body and a harness. Acuras with these transmissions have supposedly been recalled. Why hasn't Chrysler done the same before someone gets seriously injured or worse.

The transmission sometimes hunts for the proper gear. It also has tried to accelerate when slowing down to a stop. I live on a mountain and when descending I manually shift the transmission to 3rd gear, but when I do, the car will speed up before slowing down. This will cause a problem on snow covered roads. After doing some research, I found that other Jeep owner's had the same issue and re-flashing the control module did not resolve the problem, so I have not taken the vehicle back to the dealer for the re-flash.

Transmission failure. Vehicle would not shift out of third gear.

We were driving cross-country, far from home when the service light came on at 5,645 miles. Fortunately, we broke down in a city with a Jeep dealer nearby that could scan the codes. We learned that the transmission control module indicated a problem with the transmission. The dealer recommended replacing the transmission. After 5 days, we picked up our car. We have noticed rough shifting on both the old transmission and the new transmission. We have since learned that the transmission in this make/model vehicle is new and not production ready. Many customers are complaining about the same problems and experiencing close calls with vehicles hitting their stalled car on freeways and busy streets. We are very worried about our safety as the transmission continues to run rough like before. Please investigate.

Transmission responsiveness has very long (greater than one whole second) delay from driver input to actual power delivery. This leads to frequent near misses in dense traffic, particularly merging from a secondary street to a highway. I have not driven any other vehicle with a delay this extended.

When my 2015 Jeep Cherokee sport reached about 3000 miles it began having acceleration problems when I began to decelerate at stop signs, traffic lights, or in traffic. When the vehicle decelerated it always had a one or two second occurrence of rapid acceleration causing me to slam on my brakes avoiding collisions. This became worse as the car approached 4000 miles. I would then have problems accelerating into traffic and had issues with excessive rpms before shifting into the correct gear. I scheduled a visit to me dealership upon my return from vacation. The Friday before we left for our return trip home from vacation my wife put the car into drive and the Jeep shifted into reverse for several seconds before shifting into drive. Very dangerous. The very next day we were on our way home from vacation and got 4 miles on the highway (130 miles from home) when I reached 60 mph the transmission service light and check engine light came on and the car would not accelerate and began to stop in high speed traffic. We coasted off the road with my young children in back and had to be towed to the nearest Jeep dealer which was 130 miles from our house. The dealer has seen this before and seems to think it is a software issue. They will reinstall the software (which didn't work the first time) and test the car for several days. When asked if this will occur again they gave me no reassurance, saying it's software and not an actual part. I was advised confidentially by a serviceman at the dealer to speak to an attorney as I do not feel safe for my wife and young children traveling in this car without any reassurance. It is a very dangerous situation which it seems Jeep knows about but will not address correctly until fatalities occur. Should not happen with a 2 month old car. Looking at the lemon law but it seems to need 3 occurrences which by that time may lead to a fatality.

This is a newly leased vehicle. After driving at 65 mph for about 20 minutes and then stopping, a burning smell was observed. After opening hood, smoke was rising from behind the engine, but no fire. Oil was observed leaking underneath the vehicle and engine oil level had dropped below the recommended level. Oil was leaking onto the skid plate and exhaust which caused the smoke. Vehicle was driven back to the dealer for repairs. Dealer stated the oil pan seal was leaking and replaced the seal immediately at no charge to me.

Shifting with the vehicle or accelerating often has unexpected results. Shifting from reverse or park to drive results in lunging forward with increased speed. Shift from reverse to park or park to reverse can experience forward lunging. Pressing the gas, or even attempting rapid speed increase, can result in an unresponsive vehicle - no movement forward, high revs and significant rpms. After several seconds a rapid "catch" occurs and an uncontrolled jerking lunge forward.

I purchased a latitude V6 2wd 2 months ago. This past Sunday, while stopping at a stop light, the car made a dinging noise, the check engine light came on along with the message that the start/stop feature was not working. When I began to accelerate, the car would not shift gears and by the time I got to 40 mph my RPM's were at 4,000. After a mile or so, I was able to pull over and turn the car off. When I restarted the car, the check engine light remained on but it was driving fine until I got to the next stop light. The same thing happened again. On Monday, I had the car towed to the dealership. They told me that they performed updates on my car and resolved the issue. I requested them to test drive it for good measure and was assured all was well on Tuesday morning. I picked up the car on Tuesday afternoon and before I could get to the highway, the same error returned! this time I was able to accelerate normally without the RPM issue but as I was slowing my car, the down shifting was extremely rough. The service guy brought his tablet into my car and said that the errors were coming from the PCM. Today, Wednesday, he informed me that they were replacing the PCM. I should get it back tomorrow or Friday. I will follow up on this issue. 7/31 - replacing the PCM did not fix the issue. They are now replacing the transmission - which is on a 3 week backorder.

Car transmission failed, causing us to get hit numerous times. Can not accelerate when necessary, sometimes it will go fine and other times gas pedal floored and go no where.

Thank you!! the first incident occurred at 304 miles. Check engine light came on and the car started shaking and could not accelerate. Check engine light started flashing and called the dealership immediately. Had the truck towed in and they advised at first that the upper head of the engine blew, after speaking with my customer resolution rep (case number: [xxx]) the dealership called me again and advised it was just a bad spark plug and they fixed it. The second incident occurred about a week after this service I took a 200 mile trip to pa to visit family and on the way back from this trip the check engine light came on again. I checked the oil levels and there was nothing on the measuring stick. Had to car towed again and this time bayside Chrysler advised the O-ring went on the car and that it was replaced/fixed. After the O-ring service the car is still loosing oil but I can't smell is burning and there is nothing under the car after leaving a parking spot. However, when the car first starts blue smoke comes out of the exhaust and the engine knocks/tics a bit upon starting but that stops after the oil hits the engine I guess. On 8/5/2015 I started the car after work and the check engine light came on and flashing again and the car began shaking. It was towed to the dealership again this morning for service. The above covers the engine issues. Two weeks ago at a stop sign I stepped on the gas but the engine just revved for a few seconds followed by the transmission engaging. Since then the transmission has not been shifting normally. The transmission has not failed yet but it appears it's on its way. Currently the car has 2,400 miles on it. Any help would be greatly appreciated. I've been in contact with many other on forums and these people have family's/small children as do I. something needs to be done about these cars.

Went in for software update for transmission in April. Started experiencing differences in shifting which I was told would be normal and the result of the software update to prevent wear on the transmission. Gradually got worse, had moments of loss of power when trying to pass/accelerate even with the gas pedal all the way to the floor. Had moments of acceleration when pulling into traffic where there was considerable hesitation in the transmission before finally engaging in a very low gear, sticking in that gear even with rps very high, finally shifted but did not allow for proper acceleration to get out of the way of traffic in this type of situation. Also experienced issues with down-shifting when coming to stops at intersections, the transmission would not downshift in the lower gears, so all stopping power was in braking even when gradually coming to a stop which should be aided by the down- shifting of the transmission. Vehicle also was not able to maintain speeds well while in cruise control. Sometimes it would take off going over 10 mph over the set speed, sometimes it would lag well behind the set speed. Could feel transmission constantly shifting from one gear to another to try and maintain the constant speed on flat ground. Check engine light finally came on. Transmission is being replaced. Today is day 22 without my vehicle as it sits in the shop waiting for a very popular back-ordered part to be installed behind a wait list of other customers.
