2014 Jeep Grand Cherokee Speed Control & Cruise Problems

When accelerating on to the highway the vehicle will not go above the speed you were entering the highway on. For example entering the highway at 40mph and trying to get to 65mph and it will not go. Have to release the foot from the gas and then reapply foot to gas pedal. Most recent occurrence the vehicle hesitated much long resulting in oncoming cars almost rear ending me and having to drive in the breakdown lane until it picked up speed.

Car is not reporting accurate speed, 20mph or more on display and shifting my be affected

Cruise control Didn’t disengage and continue to accelerate. Tried to apply brakes but they went straight to the floor and didn’t work. Placed the car into neutral and kept trying brakes until they started to come back. With the car continuing to accelerate went into breakdown lane and rubbed up against guardrail to avoid car in front.

The headrest deployed for absolutely no reason. The car was parked and unoccupied. Upon entering the vehicle we immediately noticed the headrest was popped out. I'm thankful I wasn't driving at the time!

THE FORWARD COLLISIN CONTROL WAS TURNED ON. IT STARTED BEEPING WHEN NO ONE WAS NEAR ME AT ALL FROM ANY SIDE OF VEHICLE. THEN THE BRAKES SLAMMED LIKE IT WAS PREVENTING A REAR END COLLISIN BY MY VEHICLE. MY CAR SLID TO A STOP AT APPROXIMATELY 40 MILES AN HOUR. IT SCARED THE CRAP OUT OF ME AND I HAVE HAD THAT SAFETY SENSOR OPTION TURNED TO OFF EVER SINCE THIS INCIDENT.

I HAVE BEEN GETTING AN ERROR ON MY VEHICLE THAT SAYS "SERVICE FOUR WHEEL DRIVE SYSTEM" AND AN ERROR THAT SAYS " SERVICE ANTILOCK BRAKE SYSTEM". I'VE DONE SOME RESEARCH ONLINE AND SEE OTHER PEOPLE ARE HAVING THIS PROBLEM WITH A DRAGGING OF THE MOTOR INTO THE NEXT GEAR AND A HESITANT JERK SOMETIMES. I FOUND OUT THAT THE RIGHT SPEED SENSOR NEEDED TO BE REPLACED. IS JEEP DOING ANYTHING TO REIMBURSE CUSTOMERS THAT HAD TO PAY OUT OF POCKET.

WHEN DRIVING ON THE ROAD AND COMING TO A STOP NO PROBLEM UNTIL IT'S NEEDED TO ACCELERATE THEN THE TRUCK WILL HESITATE. WHEN GOING FROM A STOP SIGN AND MAKING A LEFT OR RIGHT THEN JEEP WILL HESITATE REAL BAD AND THE VEHICLE WILL TAKE AWHILE TO GET UP TOO SPEED

TWO MONTHS AGO, OUR JEEP DEALERSHIP PERFORMED THE V08 RECALL AS PER THE EPA/DOJ FCA ECODIESEL SETTLEMENT. SINCE THEN, I'VE EXPERIENCED LACK OF THROTTLE RESPONSE (LAG), CAUSING UNPREDICTABLE AND UNSAFE CONDITIONS WHEN MAKING A LEFT TURN AT AN INTERSECTION.

AS APPROACHING AN INTERSECTION I BEGAN TO COAST AND PLACE MY FOOT ON THE BRAKE. AT THE TIME I STARTED TO BRAKE, THE VEHICLE SURGED FORWARD FOR 1 SECOND. AS I CAME CLOSER TO A STOP, THE VEHICLE SURGED AGAIN AT WHICH POINT I HAD TO "STAND" ON THE BRAKE PEDAL TO PREVENT ME AND MY FAMILY FROM REAR-ENDING A VEHICLE AND GOING INTO A BUSY INTERSECTION.

WHILE GOING THROUGH A CARWASH THIS WEEKEND, MY CAR ACCELERATED AT SOME POINT AFTER THE GEAR WAS PUT INTO NEUTRAL, AND HIT THE CAR IN FRONT OF ME. WHEN THE BRUSHES IN FRONT OF ME PARTED I COULD SEE I WAS GOING TO HIT THE CAR IN FRONT OF ME AND TRIED TO STOP WITH THE BRAKES BUT DID NOT STOP IN TIME. A COUPLE YEARS AGO WHILE SLOWING TOWARDS THE END OF A LANE WITH MY FOOT ON THE BRAKE IT HAD ALSO ACCELERATED, CAUSING ME TO ALMOST HIT ANOTHER VEHICLE BEFORE THE ACCELERATION STOPPED. PERIODICALLY, BUT NOT OFTEN, WHEN I AM AT A STOP AND THEN PROCEED MY CAR WILL LURCH FORWARD AS IF I HAD FLOORED THE GAS PEDAL, BUT I HAVEN'T. MY HUSBAND HAS BEEN WITH ME AND SAID NOT TO FLOOR IT. I JUST GIVE HIM THE LOOK AND SAY I DIDN'T. YESTERDAY, HOWEVER, JUST HOURS AFTER THE CAR WASH INCIDENT, HE WAS DRIVING THE JEEP WHEN HE THOUGHT HE EXPERIENCED THE SAME "OVER-ACCELERATION" AFTER PROCEEDING FROM A STOP. THE CAR-WASH ATTENDANT YESTERDAY HAD ACCUSED ME OF NOT PUTTING MY CAR IN NEUTRAL BUT I HAD POINTED TO MY DASH TO SHOW HIM IT WAS IN NEUTRAL. HE DIDN'T BELIEVE ME BUT THEN LOOKED AT THEIR VIDEO WHICH WAS INCONCLUSIVE. BUT SOMETHING MADE HIM DO A GOOGLE SEARCH WHERE HE CAME ACROSS SUDDEN UNEXPECTED ACCELERATION IN JEEP GRAND CHEROKEES, AT WHICH POINT HE APOLOGIZED FOR BASICALLY ACCUSING ME OF LYING.

TAKATA RECALL I WAS DRIVING A 40MPH STREET WHEN I WAS GOING TO MAKE A LEFT TURN. I WAS WAITING FOR CARS TO PASS TO MAKE THE TURN WHEN THE THROTTLE CONTROL LIGHT CAME ON THE DASHBOARD. I WAS TRYING TO TURN BUT THE CAR WOULDN'T LET ME ACCELERATE. I AM THANKFUL THAT THERE WASN'T ANY CARS COMING TOWARDS ME. I PULLED OVER TURNED IT OFF AND BACK ON IT WENT AWAY. THE CAR HAD A RECALL IN 2017 FOR THE ALTERNATOR. I HAD A SIMILAR INCIDENT WHERE I WAS DRIVING AND THE JEEP HAD SLOWED DOWN IT COMPLETELY TURNED OFF BUT WAS ABLE TO PULL OVER AT A APARTMENT COMPLEX. THE JEEPS DASHBOARD LIGHTS WERE FLASHING THE WINDSHIELD WIPERS WERE ON REALLY FAST, EVERYTHING WAS FLASHING. I COULDN'T PUT THE CAR IN PARKING, IT WAS SMOKING. I HAD MY DAUGHTER IN THE BACK SEAT, I HAD MANAGED TO TURN AROUND GET HER OUT WHILE MY FOOT WAS ON THE PEDAL JUMP OUT OF THE CAR WITH HER IN MY ARMS. THE CAR KEPT MOVING UNTIL IT CRASHED INTO A CAR INFRONT OF IT. I FELT LIKE I WAS GOING TO DIE WITH MY DAUGHTER IN THE CAR. I FEEL LIKE THE THROTTLE COULD BE RELATED TO THE ALTERNATOR. I AM SCARED TO DRIVE MY CAR.

THE DEFROST AND TEMPERATURE WILL IT STAY CONSTANT. I CAN SET THE TEMP TO 70. IT WILL GET SUPER HOT AND MINUTES LATER IT FEELS LIKE THE AC IS ON. THE DEFROST DOESN'T WORK MOST OF THE TIME AND WILL NOT DEFROST THE MIRRORS

IN THE PROCESS OF PARKING AT MY SISTER'S HOME, I TOOK MY FOOT OFF THE ACCELERATOR AND STARTED TO BRAKE. THE CAR DID NOT SLOW DOWN. I CONTINUED TO BRAKE, BUT THE CAR KEPT GOING FORWARD WITH INCREASING SPEED. I WAS ABLE TO STEER AND NOT HIT PARKED CARS, BUT WENT INTO THE LAWN HITTING A SET OF CONTRACTOR'S SCAFFOLDING SENDING THEM FLYING INTO THEIR HOUSE AND PATIO. THE CAR FINALLY STOPPED ON TOP OF THEIR WELL HEAD, DESTROYING THE WELL COVER AS WELL AS THE PROTECTIVE PIPE FOR THE WELL HEAD. FURTHER INTERNAL DAMAGE WAS DONE TO THEIR WELL, AS THERE WAS NO RUNNING WATER IN THE HOUSE. A TOW TRUCK HAD TO COME TO LIFT THE CAR OFF THE WELL HEAD TO AVOID ANY FURTHER DAMAGE. I HAD BEEN USING THE CRUISE CONTROL EARLIER IN OUR TRIP, BUT IT WAS NOT ACTIVE AT THE TIME.

WHILE DRIVING ON THE HIGHWAY WITH NO VEHICLES OR OBSTACLES IN FRONT OF ME, THE BREAK ASSIST COLLISION AVOIDANCE WENT OFF INDICATING AN IMMINENT COLLISION AND STOPPING THE CAR. PERHAPS RELATED TO THE SAME ISSUE, A FEW MINUTES AFTER THIS INCIDENT THE COMPUTER ALSO DISPLAYED AN ERROR MESSAGE STATING THAT THE AUTOMATIC WINDSHIELD WIPERS WERE NOT WORKING PROPERLY

WITH THE VEHICLE IN DRIVE AND WHEN TRAFFIC IS CLEAR RELEASE THE BRAKE AND DEPRESS ACCELERATOR PEDAL INTERMITTENTLY I GET THE MESSAGE " SERVICE ELECTRONIC THROTTLE CONTROL" AT THAT PRECISE MOMENT, THERE IS NO ACCELERATOR, VEHICLE MAY MOVE AHEAD SLOWLY FROM AN IDLE BUT THAT IS IT. WHEN THE MESSAGE GOES AWAY THE THROTTLE RESPONDS NORMAL. THE LAST 3 TIMES THIS HAS HAPPENED I WAS COASTING DOWN HILL WITH MY FOOT OFF BOTH PEDALS.I HAVE HAD IT INTO THE DEALER SHIP SEVERAL TIMES. THIS ISSUE HAS BEEN ONGOING FOR OVER 2 YEARS NOW. BECAUSE I CAN NOT SHOW THEM THE ISSUE, WHEN I TAKE IT IN, THEY DO NOTHING.

JEEP ACCELERATED ON ITS OWN FROM 40-67MPH I TRIED TO PRESS BRAKE TO STOP CAR BUT IT DIDN'T WORK SINCE THE JEEP KEPT ON ACCELERAITING. TRIED TO SHIFT TO NATURAL AND RIDE IT OUT BUT IT WOULDN'T SHIFT IT WAS STUCK ON ACCELERATING. KILLED THE ENGINE SINCE THE BRAKE WASN'T STOPPING THE CAR SINCE IT KEPT ON TRYING TO ACCELERATE AND SINCE I COULDN'T SHIFT TO NATURAL. JEEP HAS HAD MY CAR FOR 2 DAYS AND CAN'T FIND ANYTHING WRONG WITH IT AND CLAIM THEY HAVE NEVER HEARD OF THAT ISSUE WHICH IS THE REASON I'M REACHING OUT HERE.
