TODAY WHILE DRIVING ON A HIGHWAY AT APPROXIMATELY 35-40MPH MY VEHICLE STALLED. I HAD COME TO A COMPLETE STOP AND WAS AWAITING A TRAFFIC LIGHT CHANGE. WHEN THE LIGHT CHANGED AND I STEPPED ON THE ACCELERATOR THE VEHICLE BEGAN TO HESITATE AND JERK AND THE ESP/BAS LIGHT, MALFUNCTION INDICATOR LIGHT (CHECK ENGINE) AND A MESSAGE STATING TRANSMISSION OVER TEMP CAME ON. I WAS IN THE LEFT LANE AND IMMEDIATELY PUT ON MY FLASHERS. THE DRIVER BEHIND REALIZED THAT I WAS IN TROUBLE AND PUT ON HIS AS WELL. AFTER I WAS ABLE TO ROLL TO THE SHOULDER, I IMMEDIATELY TURNED THE VEHICLE OFF. AFTER WAITING APPROXIMATELY 5MINS, I RESTARTED THE VEHICLE AND CONTINUED TO DRIVE SLOWLY AND CAREFULLY TO MY OFFICE SINCE I WAS JUST 2 BLOCKS FROM WORK. THIS EXPERIENCE SCARED ME BECAUSE HAD THIS HAPPENED WHILE I WAS DRIVING AT THE 60-65 MPH RATE ON THIS VERY BUSY HIGHWAY, I COULD HAVE BEEN HURT. AFTER READING SEVERAL OF THE OTHER COMPLAINTS, I CAN ALSO RELATE TO THE COMPLAINT ABOUT THE TIRES HAVING HAD TO REPLACE A BROKEN STEM AFTER OWNING THE VEHICLE ONLY 2 DAYS AND I CURRENTLY STILL HAVE WATER LEAKING INTO MY VEHICLE ON RAINING DAYS ON THE PASSENGER SIDE AND NOW THROUGH THE LIGHTS. I DRIVE ON THE HIGHWAY DAILY AND AFTER TODAY'S STALL OUT, I AM AFRAID TO DRIVE THIS VEHICLE. I CALLED THE DEALERSHIP TODAY AND EXPLAINED MY ISSUES AND TOLD THE SERVICE MANAGER ABOUT ALL OF THE LIGHTS AND HE TOLD ME THE CAR WAS PROBABLY COLD AND IF THE LIGHTS DON'T GO OUT I CAN BRING IT IN ON SATURDAY. WELL TODAY IS WEDNESDAY AND I WILL NOT DRIVE THAT CAR AGAIN. SINCE THE DEALERSHIP IS QUITE A DISTANCE FROM MY HOME, I WILL HAVE THE CAR TOWED SO THAT IT CAN BE CHECKED OUT. I AM VERY UNCOMFORTABLE WITH THE IDEA OF EVER DRIVING THIS VEHICLE AGAIN. I TRANSPORT CHILDREN AS PART OF MY JOB FROM TIME TO TIME AND I COULD NEVER FORGIVE MYSELF IF SOMETHING WAS TO HAPPEN TO THEM WHILE WE ARE RIDING IN THIS VEHICLE. *TR

VEHICLE ACCELERATED WHEN PUT INTO REVERSE. CHRYSLER SENT AN "INDEPENDANT" INSPECTOR, BUT THEY WILL NOT SHARE THE REPORT. IN FACT, CHRYSLER LIED ABOUT CONDUCTING THE INSPECTION. THEY TOLD ME THE INSPECTOR COULD NOT DO AN EVALUATION BECAUSE THE VEHICLE WAS "DISASSEMBLED". THE DEALER TELLS ME THE INSPECTOR SPENT TWO HOURS WITH A SERVICE TECHNICIAN AND TEST DROVE THE VEHICLE. I ALWAYS GET SUSPICIOUS WHEN SOMEONE LIES TO ME. THIS REQUIRES FOLLOW UP TO MAKE SURE THEY ARE NOT HIDING AN UNSAFE DEFECT IN THEIR VEHICLE. *TR

2008 GRAND CHEROKEE 4X4 4.7L FLEXFUEL STALLING AT VARIOUS HIGHWAY SPEEDS. THROTTLE LAGGING, HARSH UP/DOWN SHIFTING, HESITATION ON TORQUE DEMAND, FUEL MILEAGE REDUCED BY 20%. AFTER THE FIRST TWO STALLING OCCURRENCES, THE DEALERSHIP REPLACED THE FCM (FRONT CONTROL MODULE) SINCE THE SERIAL NUMBER OF THE INSTALLED ONE-337- MATCHED THE FEBRUARY 2008 RECALL, ALTHOUGH CHRYSLER DATABASE VIN RECALL SEARCH CAME BACK EMPTY??!! THE THIRD AND FOURTH STALLING EVENTS WERE FOLLOWED UP BY THE REPLACEMENT OF THE PCM (POWERTRAIN CONTROL MODULE) SINCE A "SOFT FAULT"-"TORQUE REQUEST DENIED" WAS FOUND STORED WITHIN THE CONTROLLER. HOWEVER, AFTER SIX HUNDRED MILES, A FIFTH STALLING OCCURRED. THIS TIME A HARD FAULT RELATED TO THE MAP SENSOR (INTAKE MANIFOLD ABSOLUTE PRESSURE) WAS FOUND. THE REPLACEMENT WAS SCHEDULED IN 48 HOURS. THERE WERE SIX DEALERSHIP APPOINTMENTS(ONLY TWO DOCUMENTED THOUGH ??!!) AND IT WAS INVARIABLY EITHER "WE HAVE TO ORDER THE PART" OR "THERE IS NOTHING WRONG WE COULD POINT AT". THE ALMOST NEW VEHICLE IS NOT SAFE TO BE DRIVEN ON PUBLIC ROADS. YET CHRYSLER NEVER PROVIDED A TEMPORARY REPLACEMENT UNTIL THE SAFETY HAZARD COULD BE LOCATED AND ELIMINATED. AFTER EVERY ATTEMPT OF SOLVING THE PROBLEM, THE CUSTOMER IS SENT AWAY TO TRY HIS (HER) GOOD LUCK WITH A VEHICLE WHICH MIGHT BE OKAY. I DON'T THINK THIS A PROFESSIONAL APPROACH FOR BOTH CHRYSLER AND THE DEALERSHIP SERVICING THE VEHICLE. GUESSING AND SAFETY DOES NOT BELONG WITHIN THE SAME SENTENCE ! *TR

I HAVE A 2006 JEEP GRAND CHEROKEE LAREDO, 3.7L V6. I HAVE MANY PROBLEMS WITH THE TRANSMISSION, FIRST IT WAS THE SHIFTER, SECOND IT WAS A SOLENOID PROBLEM, NOW I HAVE A SHUTTER AND VIBRATION AS I AM DRIVING DOWN THE EXPRESSWAY. I HAVE HAD IT IN 3 TIMES NOW FOR THE SAME PROBLEM. WHEN THE TRANNY STARTS TO VIBRATE, I NOTICE THAT THE RPMS GO UP ABOUT 2-3000RPMS. TOOK IT BACK AND THE REPAIR GUY SAYS THAT JEEP HAS RECALLED THE TORQUE CONVERTERS FOR A SHUTTER PROBLEM AND COULD REPLACE IT UP 100K MILES. I HAVE OVER 100K AND IT WILL NOT GET FIXED UNDER THIS RECALL OR TSB DUE TO MILEAGE, I THINK SOMEONE NEEDS TO TAKE A HARD LONG LOOK AT THE TIME THAT CHRYSLER SHOULD HAVE TO REPLACE AT THEIR EXPENSE. THIS ISSUE HAS COST ME WELL OVER $1000 SO FAR AND IT IS BACK IN THE SHOP FOR THE SAME THING YET AGAIN TODAY. *TR

TL*THE CONTACT OWNS A 2007 JEEP GRAND CHEROKEE. WHILE THE VEHICLE WAS PARKED AND TURNED OFF, A CHILD CROSSED OVER THE DRIVER'S SEAT TO EXIT THE VEHICLE. HE HELD THE GEAR SHIFT TO SUPPORT HIMSELF, WHICH CAUSED THE VEHICLE TO SHIFT INTO DRIVE. THE VEHICLE SPED DOWN A HILL AND CRASHED INTO A TREE. THERE WERE NO INJURIES AND A POLICE REPORT WAS FILED. THE VEHICLE WAS TOWED TO AN AUTO BODY SHOP AND THE MECHANIC STATED THAT THE CABLE WENT INTO THE SHIFTING GEAR, WHICH CAUSED THE VEHICLE TO SHIFT INTO GEAR WITHOUT THE KEY IN THE IGNITION. THE BODY OF THE VEHICLE WAS REPAIRED, BUT NOT THE GEAR SHIFT. THE VEHICLE IS STILL AT THE AUTO BODY SHOP. THE CONTACT WOULD LIKE SOMEONE FROM CHRSYLER TO INSPECT THE VEHICLE. THE VIN WAS UNKNOWN. THE FAILURE AND CURRENT MILEAGES WERE 43,000.

Status: closed (inferred from source dates) · Power Train:automatic Transmission:gear Position Indication (prndl)

On April 22, 2016, Fiat Chrysler Automotive US LLC, (FCA) submitted a Defect Information Report (DIR) to NHTSA regarding a defect that could result in unattended vehicle rollaway with the engine running in approximately 811,586 model year (MY) 2012 to 2014 Dodge Charger and Chrysler 300 vehicles and MY 2014 to 2015 Jeep Grand Cherokee vehicles equipped with 8-speed transmissions and a monostable gear selector (NHTSA Recall #16V-240, FCA Recall #S27). According to FCA's DIR, The existing strategies built into these vehicles to deter drivers from exiting the vehicle after failing to put the transmission into PARK have not stopped some from doing so. Drivers erroneously concluding that their vehicle's transmission is in the PARK position may be struck by the vehicle and injured if they attempt to get out of the vehicle while the engine is running and the parking brake is not engaged.The vehicles recalled by FCA are equipped with Monostable electronic (shift-by-wire) gearshift assemblies supplied by ZF Group (see Figure 1).The subject Monostable shifter has a single neutral position that it snaps back to when the driver releases the shift knob.Although the Monostable gearshift has the familiar appearance of a conventional console mechanical gearshift assembly, it has an unfamiliar movement that does not provide the tactile or visual feedback that drivers are accustomed to receiving from conventional shifters.Consequently, the driver must take additional time to verify that the desired gear position was achieved by checking the PRNDL display on the shift knob or the Electronic Vehicle Information Center (EVIC) display.

Opened Aug 20, 2015 · Closed Feb 5, 2016

Status: closed (inferred from source dates) · Power Train:automatic Transmission; Power Train:automatic Transmission:gear Position Indication (prndl)

The Office of Defects Investigation (ODI) opened Preliminary Evaluation PE15-030 on August 20, 2015,to investigate 14 complaints alleging incidents of rollaway after intended shifts to Park in Model Year (MY) 2014 and 2015 Jeep Grand Cherokees vehicles. The MY 2014-2015 Grand Cherokee vehicles are equipped with Monostable electronic (E-shift) gearshift assemblies supplied by ZF Group (ZF). The E-shift system operates electronically and the gear requested by the driver is transmitted from the shifter via the CAN Bus to the Transmission Control Module which makes the requested shift. The Monostable gearshift does not move into a detent but springs back to a centered/neutral position after the driver selects a gear and releases the shifter. A button on the shift knob must be depressed to shift out of Park, shift out of Neutral, and to shift from Drive to Reverse or Park.The gear selected is shown on a display in the dash and illuminated letters on the shifter. If the driver's door is opened when the gearshift is not in Park, a chime sounds and a message is displayed on the instrument panel to warn the driver.In addition, the engine Start/Stop push-button control logic does not permit normal engine shut-off when the transmission is not in Park. This logic may provide feedback to drivers who attempt to turn the engine off when the transmission is not in Park. However, this function does not protect drivers who intentionally leave the engine running or drivers who do not recognize that the engine is still running.NHTSA testing during PE15-030 indicates that operation of the Monostable shifter is not intuitive and provides poor tactile and visual feedback to the driver, increasing the potential for unintended gear selection.ODI?s analysis of the PE15-030 complaint and field report data identified 306 incidents of vehicle rollaway followingintended shifts to Park in the 2014-2015 Grand Cherokee. These resulted in 117 alleged crashes. Twenty-eight of the crashes reportedly caused injuries, including 3 with a fractured pelvis and 4 others requiring some degree of hospitalization (a ruptured bladder, fractured kneecap, broken ribs, damaged to right leg). Other injuries include reports of a broken nose, facial lacerations requiring stitches, sprained knees, severe bruising, and trauma to legs.An Engineering Analysis (EA16-002) has been opened to assess the scope, frequency, and safety-related consequences of the alleged defect. The Vehicle Owner Questionnaires (VOQs) associated with the closing of this Preliminary Evaluation are:10823099, 10822939, 10822442, 10820488, 10817252, 10810551, 10810051, 10809691, 10809024, 10807839, 10807416, 10794318, 10787947, 10787576, 10785790, 10783597, 10778854, 10775391, 10767488, 10766494, 10763333, 10763284, 10763082, 10762457, 10761498, 10760980, 10760729, 10760702, 10760081, 10759979, 10759669, 10759622, 10759568, 10759548, 10759533, 10759287, 10759278, 10759198, 10759186, 10759157, 10759131, 10759102, 10759082, 10759066, 10759047, 10759046, 10733158, 10730952, 10716526, 10711893, 10683556, 10679497, 10676998, 10668651, 10662619, 10662308, 10631167, 10605865, 10583366, 10567538, 10555901, and 10537653.
