While driving down the interstate at 70 mph the electronic transmission disengaged and the vehicle started decelerating to a stop.. luckily the traffic was light and I was able to pull off to the shoulder before coming to a stop. The vehicle did not roll, it started slowing as if braking., I was lucky to not be rear ended, there was no for warning and probably no brake lights. I feel the vehicle is unsafe to drive and want to know why it just shut down at 70 miles per hour, it may have resulted in a serious accident if the traffic hadn't been so light. Articles on the internet indicate the launch of the vehicle was delayed by transmission faults. I believe it was put into production faulty. Please investigate.

Again, I just got back the car from the dealership at around 4pm (12/3). The work order says that they have changed/replaced the adaption part of the car to re-learn to drive. So, I drove it home. Around 510pm, in the middle of the rain the car stopped again. Luckily again, that im not in the freeway.the same thing, the car stopped and the dashboard gave me a message to shift gear and the car started to shake/jitter. I called the tow truck and they towed it again to the glendale dealership. This is the 4th time that it happen, with the same problem. I am risking my life and my family's life. Please help!

This is the 3rd time it happened. My previous ODI # 16038484. While driving out of the parking lot the car just stopped and the car screen has a message to shift the gear. I did that and the car shakes/jitter. The parking attendant helped me to push the car on the side.

While driving, when I take my foot off the gas pedal in order to coast, the car will accelerate. While driving, when I take my foot off the gas and begin to brake, my car will accelerate. This has been happening since I purchased the vehicle on Oct 30, 2014. It was a minimal occurrence and would come and go, but now it occurs every single time I drive the car. This daily issue where my vehicle accelerates when it should not has been going on since approximately mid-late November 2014.

Second incident for this car. First incident was 10.18.14. I was parking car at a restaurant. While edging near ending point of parking space, park sense suddenly disabled and would not enable. Immediately therefore, a series of icons appeared on the dashboard in this order: 1) red lightening bolt for the etc, 2) front end collision light like I had a wreck, 3) engine light, 4) traction light. The power steering appeared very stiff. Car was still running. Drove car out of parking space and it would not accelerate; it moved at a very slow pace like it was stuck in molasses or quick sand. Placed car in park and turned off ignition. While shifting from D to P, the shift was so violent it shook the entire car and I could hear grinding. Let car rest for 60-90 seconds. Turned car back on and only the engine light remained lit. Power steering was not stiff. Drove car to dealership the next morning.

Sorry I'm not sure why it does this... when I'm driving sometimes and I take my foot off the gas to slow down.. for some reason my car on it own.. speeds up.. I watch the RPM and there is a big jump in rev.. I'm not sure what that is.. I actually lurch forward. I'm scared that one day it's going to hit a person or go through the wall of my garage! the second thing is my light switch I am not sure why but twice it's pushed into my dash board...the first time it happened I was stuck at dusk.. couldn't drive.. my normal dealership in North seattle called the dwayne lane in everett and they told my dealership that they won't do warranty work.. so my dealership had to send out a guy from service and drive all the way to everett to do a temporary fix... the third complaint.. now at 9500 miles there's a leak in my engine coolant.. and it left me stranded in everett and had to be towed.. by the way tried to go to the everett dealership dwayne lane and again they wouldn't help me this time.. I had no ride home and they wouldn't provide a rental car.. even though I paid for a very expensive extended warranty. I had the car towed the next day to marysville Jeep dealership and they are wonderful! don't buy from dwayne lane in everett!!!! the service department is the worst in the country. I've heard many horror stories from clients.. to tow truck drivers.. to other dealers.

At a highway cruising speed, when the gas pedal is released and the car is allowed to decelerate itself without pressing the brake, at certain downshifts the car will experience a jump in engine RPM of 1000 and the car will lurch forward and accelerate on its own. This is especially dangerous when going around curves or if there were ice on the road or the car were hydroplaning. Chrysler Jeep has not released a fix or a recall for this issue and it is being said that it is normal for the transmission to do this. I believe it is a dangerous condition with high potential for accidents unless fixed.

I received a phone call from my wife who was on her way home from work at approximately 1825hrs. She went on to explain to me that her vehicle was "acting" up again with all the same symptoms as last time (first incident has already been submitted under same information). She lost a significant amount of power while traveling on a busy highway where the speed posted is 65mph. When this happened she pulled off to shoulder and took photographs with her iphone to keep for our records and to what her dash was displaying. She stopped while on the shoulder and put the vehicle in park and turned off the ignition. After some time she turned the ignition on and put the vehicle in drive when she noticed the vehicle "jerked" and made a loud clunky noise. This is the second incident. The first incident dealership was unable to find any problems under the diagnostics they ran.

- Hemet, CA, USA

On the above date while traveling to work my wife called me and informed that her vehicle had lost power during operation on a busy highway. Upon further explanation she informed me while accelerating to the proper speed for the posted speed limit of 55mph the vehicle had lost power and the "service transmission" light illuminated. She then pulled off the busy road to a safe a spot and proceeded to contact our insurance and the local Jeep/Chrysler dealership, as we are currently under warranty. Once I arrived to my wife's location we waited for the tow truck and upon his arrival he asked if the vehicle could be driven, at this time I turned on the vehicle and placed it in drive, the "service transmission" light was still on. I was able to drive in approximately 3 miles to the dealership all awhile being followed by the tow truck and without incident.

The car is only 5 months old. Has a zf 9 speed automatic transmission and 3.2L 46 24V -vvt engine. I was driving on a tollway in moderate traffic at a speed of approximately 60-65 mph. Without slowing down or changing speed, the display on the dash listed "service transmission". all power to the engine was lost and car began to slow down. Would not respond to acceleration. Check engine light, stability control light, P! were all displayed. Had to find a way to the shoulder and stop car. Turned off car and restarted it. "check transmission " was displayed. Put it in drive and it felt like it was starting in 2nd or 3rd gear. Would not shift gears. Could get up to 35 mph with the tach at 2000 RPM. Would not shift at all. Got home and let car sit for a few hours. Started car after sitting for a few hours and the "service transmission" was gone. All other warning lights were gone except for service engine light. Drove to dealer next day and car appeared to shift ok. Dealer loaded PCM flash update. Reprogrammed tcm per tsb 21-018-14. Reprogrammed rf hub per 08-077-14. Car appears to be driving ok. Dealer said they couldn't find any problems with the transmission. They treated this very lightly. I feel this is a significant safety issue. Lost all acceleration and control at high speed. No notification of updates were sent previously.

When decelerating for a speed zone, the transmission downshifted from 5th to 4th, the rpms went up approximately 1000 and the car accelerated. The 'unintended' acceleration characteristic is also evident on downhill driving in the mountainous terrain. This occurs or a frequent basis and was evident prior to, and after, a transmission/tcm replacement. My wife no longer feels safe driving this vehicle and has gone back to using her Subaru for commuting. There are obvious issues with the engine/transmission control firmware/hardware which need to be addressed.

- Weaverville, CA, USA

At freeway speed of 65, the vehicle suddenly had no power, went into neutral, and "service transmission" warning came on. Upon trying to accelerate to pull to the shoulder, the engine would simply rev rpms but provided no power, even after trying to shift between neutral and drive. After getting to the side of the road, the vehicle was shut off and turned back on, at which time the service transmission light was still on, but the vehicle worked again. The dealer replaced the entire transmission under warranty but provided no explanation of why it suddenly lost all power on the freeway and could have easily caused a wreck when trying to get over several lanes on a busy freeway.

While parking the vehicle, the parksense feature disabled on its own. Immediately thereafter, the red lightning bolt indicator light appeared on the dash, which has been known to be associated with the electronic throttle control, glow plugs, swirl motor failure (low pressure in rail or fuel rail pressure malfunction) and also speed sensors. The vehicle then revved up on its own without acceleration while my foot was positioned firmly on the brake pedal. Immediately following that, the word "transmission" appeared on the dash, then the check engine light, then the collision indicator as if a car crash had occurred, which it had not. Finally, the power steering became very stiff. Drove the vehicle to the dealership it was purchased from and they said the codes were unknown like hieroglyphics. Left vehicle there. The following Monday the dealership informed me there were 3 software upgrades that were needed on the vehicle, however, those upgrades did not correct the problem. Technician also informed me the car was not safe to drive and they didn't feel safe driving it themselves and got off of the highway during a test run. The technician further explained the vehicle had 3 test runs and failed all 3 and it was beyond their expertise so Chrysler engineers would be consulted this week. Lastly, the technician informed me I "may be ahead of a recall issue." The car is 5 and half months old. I ordered the car, meaning, I had it made/built from the manufacturer. It was not a car purchased from the lot. Therefore, no other drivers of the car and it is brand new. It is a safety concern, especially since the Cherokee has been out of production for many years until the 2014 release. As a side note, I remember an incident that occurred the week prior when the vehicle had difficulty shifting gears (automatic transmission). Instead it stalled and revved on its own.

When accelerating from a stop, between 13-20 mph just before the transmission shifts into the next gear the whole vehicle shimmies or wobbles for a few seconds. It happens every time, whether under hard or soft acceleration. It is also more noticeable when turning right. The passenger is even able to feel the shimmy, so it does not only transfer through the pedals or steering wheel. Axles have been replaced, software has been updated, but at this point in time there is no known fix for the vehicle.

The contact owns a 2014 Jeep Cherokee. While the vehicle was parked and started, the engine idled up and down and caused the rpms to increase and decrease. During the failure, the check engine and transmission sensors illuminated. The vehicle was not diagnosed or repaired. The manufacturer was not notified. The failure mileage was 2,200.

- Fateyetteville , GA, USA

When driving at highway speeds (68 mph) and slowing down, the gears on the 2014 Jeep Cherokee downshifted, resulting in an increase in speed, despite pressure being applied to the brakes. This occurs with the automatic transmission when braking change gears from 4th to 5th gear. The shift into 4th gear is followed immediately by a 500+ RPM increase in the engine. If heavy, consistent pressure is not applied to the brake, the car will accelerate 1-2 mph. If heavy, consistent pressure is applied to the brake, the car shifts violently and the car "lurches" forward due to the increase in RPM.

- Baltimore, MD, USA

I was driving on the expressway doing 60mph. I merged into left lane and began to accelerate to speed limit. Reached 65mph and transmission stalled and threw my vehicle into neutral. I had to pull over onto the shoulder to turn off vehicle and restart. Check engine light remained on as well as message to check transmission. After returning it to the dealership twice, the same thing happened again on 9/22/14 with mileage at 1195.
