2015 Jeep Grand Cherokee Speed Control & Cruise Problems

While driving shifting gears on its own without my control. Slowed me down on freeway from going 50 mph to 35 mph without me slowing it down as I am driving. I was still pushing gas pedal buy while shift was in normal drive from went from 8 to a 3 without my control so I had to pull over because I could not go any faster at all and was in danger zone on freeway that had up to 70mph driving. Once I parked I turned call completely off and then restarted after a min or so it still did the same thing as I drove causing me to pull over more than 2 times. Very dangerous and was not prepared for something like that on busy and fast place as we all know the freeway/highway is. That could of been a total loss for me and other drivers.

The Traction control light comes on while driving, once that happens it changes the performance of the vehicle it stays in one and it doesn’t allow you to do more then 43 at the most.

When setting cruise control to speed limit then pressing brake and then resume the jeep sone times accelerates to a higher speed the. Having to break again. Has been reoccurring nervous when driving and setting cruise or resuming. Have not taken it in as of yet.

While in Starbucks drive through, my vehicle suddenly accelerated and hit the vehicle in front of me.

IT WAS FREEZING OUTSIDE, BUT NOT ICY ON THE ROAD. WELL LIT. I WAS NOT IN A RUSH. CAR WAS IN EXCELLENT SHAPE UP UNTIL THEN. I WAS GOING ~10 PMH DOWN THE INSIDE PARKING GARAGE DRIVEWAY. HAD TO PULL TO THE RIGHT DUE TO CAR COMING UP PARTIALLY ON MY SIDE. SCRATCHED THE SIDE WALL. ONCE THAT HAPPENED, THE CAR ACCELERATED OUT OF CONTROL. BRAKES DIDN'T REACT. ONLY WAY TO STOP THE CAR BEFORE RUNNING INTO OTHER CARS OR EVEN PEOPLE WAS STEERING THE CAR INTO THE WALL FRONT ON. THE CAR FINALLY STOPPED, THE WALL BROKE DOWN. THE AIRBAGS DIDN'T GO OFF, THE BRAKE ASSISTANCE SYSTEM DIDN'T KICK IN. FORTUNATELY NOBODY WAS HURT, BUT COULD HAVE EASILY HAPPENED. THE CAR IS A TOTAL LOSS. I WAS NOT UNDER THE INFLUENCE OF DRUGS AND DON'T HAVE A SEIZURE DISORDER. WITNESSED EVERY SINGLE SECOND FULLY AWAKE AND AWARE.

I WAS EASING OUR 2015 JEEP GRAND CHEROKEE INTO A PARKING SPOT AT A TRAIL HEAD PARKING LOT WITH MY FOOT ON THE BRAKE PEDAL. I FULLY ENGAGED THE BRAKE PEDAL TO STOP THE VEHICLE, AND THE VEHICLE ACCELERATED AT FULL THROTTLE OVER THE TOP OF A 2.5 FT BY 2.5 FT CEMENT BLOCK PARKING BARRIER. IT DRAGGED THE CEMENT BLOCK ABOUT 20-25 FT. I CONTINUED TO PRESS THE BRAKE AND AFTER ABOUT 40 FT, THE VEHICLE CAME TO A STOP. I IMMEDIATELY TURNED THE VEHICLE OFF. IT WAS TERRIFYING NOT TO BE IN CONTROL OF THE VEHICLE. FORTUNATELY, NO ONE WAS INJURED. DAMAGE TO THE VEHICLE IS YET TO BE DETERMINED, BUT EVEN IF IT IS REPAIRED, THERE IS NO WAY I WOULD FEEL COMFORTABLE DRIVING IT AGAIN. THIS VEHICLE SHOULD BE TOTALED AND NOT RESOLD TO ANYONE ELSE. I HAVE BEEN A LOYAL JEEP OWNER FOR OVER 20 YEARS, BUT I AM NOT SURE I WOULD PURCHASE ANOTHER ONE, ESPECIALLY NOW THAT I HAVE RESEARCHED THE ISSUE AND REALIZE THAT THIS IS A RARE BUT REOCCURRING PROBLEM WITH THE JEEP GRAND CHEROKEE FOR 20+ YEARS.

PREVIOUSLY ENTERED COMPLAINT REGARDING COLD THROTTLE/TURBO LAG OF 3-5 SECONDS WHICH IS DANGEROUS FOR PULLING INTO TRAFFIC AND ALMOST CAUSING ACCIDENTS BUT THIS IS NOT LIMITED TO COLD VEHICLES. THE LAG IS SHORTER BUT EVIDENT WHEN WARM. I HAVE HAD SEVERAL INCIDENTS OF HITTING THE LAG WHILE TRYING TO TURN IN AN INTERSECTION AND THERE IS A "FLAT SPOT" LAG OF 2 -3 SECONDS. PRESSING THE GAS PEDAL IN STOP AND GO TRAFFIC CAN CAUSE A LAG THEN SURGE FORWARD. I HAVE ALMOST HIT THE CAR IN FRONT OF ME SEVERAL TIMES AND HAD DIFFICULTY SWITCHING LANES BECAUSE I GET THE NOSE OF THE VEHICLE TURNED INTO ANOTHER LANE THEN IT DOES NOT MOVE CAUSING NEAR COLLUSIONS THEN SURGES FORWARD. THIS IS EXTREMELY DANGEROUS AND I AM BEGINNING TO BE FRIGHTENED OF DRIVING THIS VEHICLE FOR EVEN THE SHORTEST OF TIMES.

THE CHECK ENGINE LIGHT CAME ON AND THE VEHICLE'S ELECTRONIC THROTTLE CONTROL SYSTEMS WAS INOPERABLE. UPON STOPPING AND RELEASING THE BRAKE THE VEHICLE LUNGES FORWARD ACCELERATING SUDDENLY TO 20 MILES PER HOUR. WHEN PLACE IN REVERSE THE VEHICLE AND RELEASING THE BRAKE THE VEHICLE LUNGES AS WELL. ADDITIONALLY, WHEN THE CHECK ENGINE LIGHT AND ELECTRONIC THROTTLE CONTROL INDICATOR LIGHT IS ON, AFTER LUNGING, THE VEHICLE WILL NOT ALLOW YOU TO ACCELERATE BEYOND 30 TO 40 MPH AFTER THE INITIAL LUNGE. I HAVE HAD TWO INCIDENTS THAT HAVE DAMAGED MY CAR. IT ONLY HAPPENS WHEN THE VEHICLE IS IN DRIVE OR REVERSE MAKING IT UNSAFE TO OPERATE.

RECEIVED A SERVICE SHIFTER MESSAGE WHILE GOING FROM PARK TO DRIVE ON DASH BOARD DISPLAY RECENTLY 3 TIMES. I READ ONLINE OTHERS HAVE EXPERIENCED THIS SAME ISSUE.

WHILE DRIVING IN STOP AND GO TRAFFIC I WAS STOPPED WITH MY FOOT IN THE BRAKE PEDAL THE ENGINE STARTED REVVING INTO HIGH RPMS THE CAR STATED SURGING AND THE BRAKES WOULDN'T STOP THE CAR. I REAR ENDED THE VEHICLE IN FRONT OF ME. *JS

DRIVING DOWN AN OPEN ROAD, SUDDENLY THE "BRAKE NOW" WARNING STARTS BEEPING AND BRAKES ARE AUTOMATICALLY APPLIED. THIS HAS HAPPENED SEVERAL TIMES WITH NO VEHICLES, ETC IN FRONT OF THE VEHICLE. HAPPENED EVEN AFTER THE RECALL WAS COMPLETED ON IT FOR THE CRUISE CONTROL SYSTEM.

THE INCIDENT OCCURRED ON OR ABOUT THURSDAY, APRIL 10TH 2019 AT 12:10AM. IT INVOLVES THE BRAKES OF THE VEHICLE NOT BEING ABLE TO STOP THE VEHICLE AT LOW SPEEDS. THE ENTIRE INCIDENT WAS CAPTURED ON A HIGH-QUALITY FRONT-FACING DASHBOARD CAMERA WITH AUDIO, VIDEO, AND GPS. THERE WERE NO INJURIES. DESCRIPTION OF THE INCIDENT IS AS FOLLOWS: WHILE I WAS ON THE INTERSTATE 10 WEST FREEWAY IN REDLANDS, CA, I MANEUVERED TO THE MOST RIGHT LANE ON THE HIGHWAY IN PREPARATION TO APPROACH AN EXIT LESS THAN 1 MILE AWAY (UNIVERSITY AVE.) DUE TO LANE CLOSURES (LEFT LANES) AT THE TIME I WAS ON THE FREEWAY, TRAFFIC WAS BUMPER-TO-BUMPER AND VERY LOW SPEED. WHILE IN THE MOST RIGHT LANE AND STILL AT VERY LOW SPEED, I ENGAGED THE ADAPTIVE CRUISE CONTROL FEATURE ON THE VEHICLE. WITHIN AROUND 5 SECONDS OF ENGAGING THE ADAPTIVE CRUISE CONTROL, THE VEHICLE SLOWED DOWN TO A STOP BECAUSE OF THE VEHICLE IN FRONT OF MINE HAD STOPPED. AT THAT POINT, THE CRUISE CONTROL FEATURE SELF-DISENGAGED AS NORMAL. ONLY A FEW SECONDS LATER, THE VEHICLE POSSIBLY ABNORMALLY VIBRATED. AS THE VEHICLE CONTINUED TO CREEP FORWARD IN TRAFFIC AS NORMAL, I APPLIED THE BRAKES TO STOP, BUT THE VEHICLE WOULD NOT STOP OR SLOW DOWN. AS I NEARLY APPROACHED COLLIDING WITH THE VEHICLE AHEAD OF ME, I ENGAGED THE PARKING/EMERGENCY BRAKE WITH MY FOOT, AND THAT DID NOT SEEM TO SLOW OR STOP THE VEHICLE EITHER. A SECOND ATTEMPT TO ENGAGE THE PARKING BRAKE DID NOTHING AS WELL. WITHIN A FEW SECONDS, THE CAR ALMOST SLOWED TO A STOP DUE TO ROLLING FRICTION AND A SLIGHT UPHILL GRADE IN THAT PORTION OF THE FREEWAY. I PLACED THE VEHICLE IN PARK AT THIS TIME AND RESTARTED THE CAR. AFTER RESTARTING, I WAS ABLE TO DRIVE AND BRAKE PROPERLY THE REST OF MY SHORT JOURNEY HOME. THIS ENTIRE EPISODE IS CAPTURED ON MY DASHBOARD CAMERA, AND IT SEEMS OTHERS ON THE INTERNET HAVE COMPLAINED ABOUT THIS ISSUE AS WELL.

NOTE: I ENTERED AN ERRONEOUS VIN NUMBER ON MY COMPLAINT A FEW MINUTES AGO. MY DESCRIPTION OF THE PROBLEM WAS LISTED ON THAT COMPLAINT.

DRIVING MY GRAND CHEROKEE ON I-40 WITH CRUISE CONTROL SET TO 75, I ENTERED A CONSTRUCTION ZONE AND APPLIED THE BRAKES TO SLOW DOWN. INSTEAD OF SLOWING DOWN, THE CAR ACCELERATED UP TO ABOUT 90 MPH. I WAS SPEEDING IN AND OUT OF TRAFFIC LIKE A MAD PERSON AND, LUCKILY, I MANAGED TO KEEP MY WIFE AND I ALIVE. THEN THE BRAKES WERE ON THE FLOOR, I COULD NOT DISCONNECT THE CRUISE CONTROL, COULD NOT SHIFT OUT OF GEAR AND COULD NOT TURN THE CAR OFF. AFTER A PERIOD OF TIME, WE BEGAN A SLIGHT INCLINE AND THE CAR SLOWED. THEN I HAD CONTROL FOR A SHORT TIME WHEN THE POWER STEERING WENT OUT; IT CAME BACK ON AFTER ABOUT A MINUTE. WE WERE TOWED TO THE NEAREST DEALER (70 MILES) AND THE CAR REMAINED THERE IN ORDER FOR CHRYSLER TO SEND A TEAM TO INVESTIGATE. AFTER 4 WEEKS CHRYSLER INFORMED ME THAT THERE WAS NO PROBLEM. TELL THE TRUTH, I COMPETELY EXPECTED THEM TO NOT TAKE BLAME FOR THIS. THIS WAS THE MOST FRIGHTENING THING THAT HAS EVER HAPPENED TO ME - I THOUGHT FOR SURE THAT WE WOULD BE KILLED - WEAVING IN AND OUT OF DIESEL TRUCKS AND CONSTRUCTION ZONE. I TOOK OUT BARRIERS AND TRAFFIC CONES IN MY EFFORT TO SAVE US. I HAD SERIOUS CONCERNS ABOUT OPERATING THIS VEHICLE AGAIN BUT MY THOUGHT IS THAT CHRYSLER PROBABLY FIXED THE PROBLEM WITHOUT TAKING RESPONSIBILITY FOR IT. I DID DISCOVER THAT THERE IS SOMETHING YOU CAN DO IF YOU ARE IN THIS PREDICAMENT AND I WISH I HAD KNOWN ABOUT IT BEFORE. IF YOU HOLD IN ON THE START BUTTON FOR A FEW SECONDS, THE CAR WILL TURN OFF. I HAD HELD IN ON THE START BUTTON BUT, EVIDENTLY, NOT FOR LONG ENOUGH. I HOPE THAT THIS MESSAGE CAN GET OUT TO OTHER JEEP OWNERS AND THAT THIS ACTION COULD SAVE LIVES.

VEHICLE'S FORWARD COLLISION WARNING (FCW) SYSTEM ACTIVATED A BRAKE! ALERT WITH NO HAZARD PRESENT. DRIVER INFORMATION CENTER KEEPS DISPLAYING MESSAGE INDICATING ACC (ACTIVE CRUISE CONTROL)/FCW SYSTEM NOT AVAILABLE OFF & ON. VEHICLE WAS IN MOTION AT THE TIME OF THE FALSE ALERT.

I'VE READ ABOUT A RECALL REGARDING THE CRUISE CONTROL BUT HAVEN'T RECEIVED THE NOTICE AND MY DEALER WILL NOT TAKE CARE OF THE PROBLEM WITHOUT IT. I WANT IT FIXED SO I CAN USE MY CRUISE CONTROL

I OWN A 2015 JEEP GRAND CHEROKEE LAREDO LIMITED, PURCHASED FROM A DEALER NEW. LAST WEEK I PULLED INTO MY DRIVEWAY, TURNED THE JEEP OFF AND WENT TO GET OUT AND MY ALARM SYSTEM WENT OFF. COULD NOT TURN IT OFF WITH EITHER FOB, I WAS EVEN ABLE TO START IT UP AND DRIVE. REMOTE START WOULD NOT WORK FOR 3 DAYS. CRUISE CONTROL JUST TURNS OFF WHEN IT WANTS WHILE DRIVING ON INTERSTATE OVER 60 MPH. GPS STATES I'M OFF ROUTE AND FREEZES IN THE LOCATION WHERE IT HAPPENED ON INTERSTATE, NORMAL WEATHER(NO OVERCAST/FOG). WIPERS JUST START WORKING WHILE SITTING IN THE DRIVEWAY IDLING, AS YOU'RE DRIVING...NO DUST, RAIN, BUGS ETC...WINDSHIELD LEAKS AND RAIN COMES IN FROM BEHIND THE REARVIEW MIRROR/SUNGLASS HOLDER WHEN IT RAINS AND YOU HAVE TO TAKE A SHARP TURN(NOT WITH NORMAL TURNS)...LEAKS DOWN ON CELL PHONE WHICH SITS IN LITTLE CUBBY TO CHARGE. THE VEHICLE SURGES WHEN GOING UNDER 20 MPH, USUALLY WHEN YOU ARE TRYING TO START FROM A STOP IS WHEN IT' WORSE. UNDER 25K MILES AND I AM AFRAID AS TO WHAT MIGHT HAPPEN NEXT.

TL* THE CONTACT OWNS A 2015 JEEP GRAND CHEROKEE. THE CONTACT STATED THAT THE VEHICLE HESITATED TO ACCELERATE WHEN THE ACCELERATOR PEDAL WAS DEPRESSED. THE CONTACT STATED THAT THE SPEEDOMETER READ A HIGHER SPEED THAN THE ACTUAL SPEED OF THE VEHICLE. THE CONTACT RECEIVED NOTIFICATION OF NHTSA CAMPAIGN NUMBER: 16V529000 (POWER TRAIN) HOWEVER, THE PART FOR THE RECALL REPAIR WAS UNAVAILABLE. THE CONTACT STATED THE MANUFACTURER EXCEEDED A REASONABLE AMOUNT OF TIME FOR THE RECALL REPAIR. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE THE FAILURE MILEAGE WAS APPROXIMATELY 32,000. PART DISTRIBUTION DISCONNECT. UPDATED 03/01/17*LJ *CN

WHILE DRIVING THE 2015 JEEP GRAND CHEROKEE ON CRUISE CONTROL, I NEEDED TO ACCELERATE TO AVOID A TRAFFIC SITUATION. I STEPPED ON THE ACCELERATOR AND NOTHING. IT DID NOT ENGAGE TO SPEED UP EVEN THOUGH I PUSHED THE ACCELERATOR ALL THE WAY TO THE FLOOR. I REMOVED MY FOOT FROM THE ACCELERATOR AND STEPPED ON IT AGAIN, HOPING IT WAS A FLUKE, BUT STILL NO ACCELERATION. IT DID MAINTAIN THE SET CRUISE SPEED OF 65 MPH. IT TOOK APPROXIMATELY 15 TO 20 SECONDS OR MORE BEFORE THE ACCELERATOR FINALLY ENGAGED. I HAD DRIVEN THE VEHICLE EARLIER IN THE WEEK FOR ONE 8 HOUR STRAIGHT AND TWO 3 HOUR STRAIGHT TRIPS WITH NO ISSUE. ON THIS TRIP I HAD DRIVEN THE VEHICLE FOR 5 HOURS PRIOR TO THIS EVENT. STOPPED AND RESTED FOR ABOUT AN HOUR AND THEN PROCEEDED TO COMPLETE MY TRIP. ABOUT 3 HOURS INTO THIS LAST LEG IS WHEN THIS HAPPENED. IT HASN'T HAPPENED BEFORE OR SINCE (YET). I HAVE PREVIOUSLY REPORTED TO THE DEALERSHIP THAT THERE ARE MANY TIMES A BRIEF, SECOND OR SECOND AND ONE HALF DELAY FROM WHEN I STEP ON THE ACCELERATOR BEFORE THE ACCELERATOR ENGAGES. THIS IS SPORADIC AND DOESN'T SEEM TO BE A CONSISTENT PROBLEM. THE SALESMAN AND THE GENERAL MANAGER INDICATED THEY HAVEN'T HEARD OF THIS PROBLEM FROM OTHER OWNERS. I UNDERSTOOD THIS IS AN INHERENT PROBLEM WITH THE TOYOTA TUNDRA AND ASSUMED IT TO BE RELATED TO THE ELECTRONIC ACCELERATION PROCESS AS COMPARED TO THE OLD CABLE ACCELERATION LINKAGE IN YEARS PAST. I HAD IN FACT UPDATED THE SOFTWARE RELATED TO THE RECENT RECALL THROUGH THE UCONNECT WEB SITE, AT LEAST A WEEK BEFORE THIS EVENT.

TL* THE CONTACT OWNS A 2015 JEEP GRAND CHEROKEE. THE CONTACT STATED THAT WHILE DRIVING AT AN UNKNOWN SPEED, THE VEHICLE AUTO ACCELERATED WITHOUT WARNING. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 5,500.
