Problems with 2012 Jeep Grand Cherokee VEHICLE SPEED CONTROL

My grand cherokee has stalled several dozen times over the past few years and the dealer can't fix it. the car stalls when slowing to a stop or turning through an intersection but we can't duplicate the problem at the service center. the dealer kept the car for nearly a month trying to duplicate the problem but could not, but i have kept records over the past year of all stalls and the conditions and the only condition that remains constant is that i am quickly braking from 40 mph or faster or i am braking while turning. initially it only occurred while turning left, but now it occurs while turning right and while braking quickly while going straight. i have been in several near misses due to losing power steering and brakes and i am to the point to where i can't allow anyone but me to drive the car due to the safety factor. twice i almost hit a car while turning and once a big rig almost hit me in the side as the car stalled mid-intersection of a six lane highway. the car is still under chrysler's warranty, and as noted, the dealer has tried to fix the problem, but has failed time after time. the problem has occurred dozens of times but the latest time was today, at which point i decided to submit this complaint. although i can't duplicate the problem on demand, there are 3locations where it most often occurs, and it most often occurs in the morning. the first location is about 2.5 miles from my house, and the other two are 5 miles each from my house. two of the three locations are at intersections with red lights, while the third is simply the location of where i work where it has stalled multiple times while just turning into the driveway. it also has stalled several times while coming home or just driving around or on vacation. dealer has replaced fuel pump relay, wiring, and some emission control parts.

I was pulling into a parking spot and transitioning the vehicle to park when the vehicle accelerated. i had my foot pressed firmly on the brake but it did not stop and it went up and over a parking barrier into another parked vehicle.

Car began to sputter and rise in rpms and missing gear going into nuetral and causing dangerous situations in traffic runs at 2 rpms in ideal standpoint now car is leaking fluids and service 4wheel drive lights on i read that there are recalls for this issue in other keeps but not for my vin number and this is a manufacturer problem

Vehicle loses all power when slowing down or stopped. lose ability to steer. have to restart the vehicle.

1. jeep dies for no reason when decelerating it happens at highway speeds when taking the foot of the gas it last happened on highway 1 on a big curve, steering and brakes lost power on a cliff side road.(scared me and the family 1/2 to death) it has happened on the dumbarton bridge in commute traffic it also happens when decelerating on off ramps or coasting to stop lights. you need to completely stop the car put it in park and press on the brake to restart it. this in traffic is also dangerous jeep says 10 things may cause it and they will not fix try any of then because they cannot pinpoint which one it is. 2. cruise control slams on the breaks for no reason. another dangerous problem no cars in front of me, open highway, no overhead bridges or guard rails in sight and the brakes slam on.

Vehicle randomly shuts off while driving. no indications of problem as far as warnings. loses all engine power, power steering, power brakes. happens when slowing. once shifted to neutral or park, it will restart without issue. intermittent dangerous problem. no faults active, no diagnosis to be found. vehicle is up to date on recalls as far as we can tell. concerns for safety are present. vehicle currently has 128929 miles, but this has happened 3-4 times a year randomly since we purchased it at 33k in 2014.

My acc sensor will not connect therefore my cruise control does not work, leaving useless buttons on my steering wheel. we have no idea what is wrong with the whole system. took it to the dealership and while they were doing recall work, they checked it. said i would have to buy the $2,000+ acc unit and then it would probably be $1,000+ labor and then however much if they have to replace wires or anything else. i just want my cruise to work, i don't care if the distance part works. warranty would not cover it and i'm sure i no longer have any factory warranty left on my vehicle.

Car lost all power for steering and braking. car stalled. was at low speed 5-8mph turning to the right into a gas station driveway from busy roadway of speeds of 55mph. car went straight and rolled to a stop. grateful was parking lot and ditch in front of me and not the gas pumps or another vehicle as i had no control of the car stopping. i have twice had car to dealer for car going into limp mode. both in year 2016. same cylanoid each time.

Vehicle stalls when applying brakes while decelerating. all power is lost and very difficult to steer or brake. the vehicle will restart when put back into park after drifting to a stop. this is a random problem that occurs 1-2 times every couple of weeks on average. the problem has been reported to jeep and has been at the dealer several times but they cannot reproduce the problem and there are no engine codes being generated. this is a very dangerous hazard and i have simply been lucky i have not been in a serious accident yet as a result.

Jeep was turned on while brake was applied. engine began to rev, jeep then lurched forward while brake was still applied. jeep came to stop approximately 40 feet from where the jeep was turned on. it was a scary ride, no control over the vehicle. *tr

My 2012 jeep grand cherokee laredo has stalled when turning on and has often not turned on. when driving the vehicle the car has shut off almost causing an accident.this has happened on many occasions. the car accelerates often when driving the lights, airbag symbols, etc turn on erratic. i had to replace the alternator and battery due to faulty timp which jeep has recalls on however not my year although-my car has the same problems which i have to pay for and i have researched and many other jeep owners have the same issues and jeep is very aware and are not taking responsibility, i feel unsafe driving this car especially with my children, the car is unreliable and have been late to work due to the car stalls and lack og turning on. this car has a mind of its own starts when it feels like it, speeds up on its own, lights turn on off,tells u keys left the car when it hasn't. very angry at jeep i should not have to pay for faulty equipment due to your negligence! *tr

I was driving my jeep from a stop sign and it all of a sudden slowed down and would not accelerate. the engine light comes on and forces me to pull over, restart it and it runs fine after that. well, it's happened 3 times after this and i have arranged a 7am service for it on monday. the book says check the gas cap or it may be bad gas, but i burned the gas down to 15 miles left and filled it with super unleaded. no matter what i do, like shift into n, rev the engine, nothing works until i pull over and restart it. *tr

Problem developed just after 10,000 miles with mild vibration on acceleration. problem persisted and got worse. i had vehicle checked by dealer and head mechanic at 15,000 when in for oil change. definitely was a problem, took a day to diagnose with help from jeep. /chrysler said it was failure of the transfer case/drivetrain control module. it took from june 25 until august 19 to obtain new module. during that time vehicle vibration worsened further requiring backing off on acceleration and then continuing acceleration to get up to highway speed. very much like riding on a bad washboard road plus noise coming from under front and then additional noise from rear. when going up moderate inclines back end began strongly vibrating to the point where it felt back end was going to start hopping plus a clunk noise. backing down acceleration and then reaccelerating would lessen problem but still made vibration. final cause after repair: cause listed as broken propeller shaft with universal joints, replaced transfer case to rear axle; replace rear prop shaft due to carrier bearing failure causing vibration; replace final drive control module per diagnosis for shuttering in driveline. vehicle has 17,578 miles at repair completion. problem appears fixed in the first 500 miles i have driven since repair. *tr

Multiple incidents - stopped at corner heading uphill. happened to touch both brake and gas pedals at the same time. i found that when going into the intersection at the change of light, no gas (propulsion) for approx. 5 seconds. complained to service mgr. he advised he had heard this before and would contact chrysler. never heard from him again. over the two years this problem occurred about 4 times. i have since been told that nissan has also engineered this into their cars as if this makes it right. *tr

Cold started vehicle. waited for fast idle to subside (cool weather). placed in drive and slowly accelerated into garage, appr 30 feet. braked vehicle to full stop. vehicle seemed to be under some level of power, more than idle speed with no acceleration by driver. began to shift out of drive and once the shift lever was in the neutral slot, the engine rpms increased to about 4000 rpm. engine was shut down in neutral to avoid shifting into park at high rpm. second occurrence on 15nov2012, same situation. contacted local dealer (bb - chrysler jeep) (16nov2012 0931), spoke with pm - service consultant who stated that there were no recalls or service bulletins on this vehicle for acceleration type problems. he recommended to bring in for inspection if it happens again. *tr

Yesterday, 5 jan 12, as i approached a stop light i removed my foot from the gas and applied the brakes. the vehicle did not slow down as expected. it was as if the engine was fighting me. i put the car into neutral and the rpms shot up to about 5000 and then went back down. the cruise control was not engaged and my foot was on the brake, not on the gas. today, as i was coasting towards an intersection, foot off the gas, i stepped on the brake and again the engine revved up causing me to have to press very hard on the brake to stop. after no more than one or two seconds the problem disappeared. this could easily cause a serious accident. *tr

I was going approximately 20-25 approaching a signal light. i let off the gas and applied the brake as the light was red. as i let off the gas, the engine began to rev higher and as i applied the brake i had to apply it harder and harder as the engine continued to rev even higher. i began to smell the brakes burning as they tried to hold the car back. fortunately i had the foresight to put the car in neutral. it continued to rev for about 5 seconds and then went down to normal. it has happened once. no warning lights went on. the dealer said that they contacted the detroit technical bureau and they suggested that maybe it was the floor mat, or my foot, etc, etc but claimed they had no other reports of this occurring. i don't have carpets as i opted for the rubber mats and they sit tight to the floor. and my foot was not stuck on the gas. i was conscious of the fact that my foot was on the brake and not the gas as i was trying to figure out what the heck was going on. they said they drove it and did computer checks and had no explanation. the service rep said the response from the technical bureau would be "insulting to me". the dealer was bradshaw jeep in watertown, ct and the service rep was victor. i wrote this out on the service order and kept a copy. *tr
