I PURCHASED MY 2000 JEEP GRAND CHEROKEE IN 1999. I HAVE BEEN IN AND OUT OF THE DEALER SERVICE FOR REPEAT MAJOR PROBLEMS. MY TIRE SQUEAKED LOUDLY WHILE DRIVING AND AFTER A YEAR OF NOT FINDING THE PROBLEM, AND FIXING WHAT THEY THOUGHT WAS THE PROBLEM THE LEFT FRONT WHEEL BEARING WAS REPLACED AND SOLVED THAT PROBLEM. DURING THE PROBLEM WITH THE SQUEAK THEY INFORMED ME THAT THE TRANSFER CASE HAD A PROBLEM AND THE SOLUTION WAS TO DRAIN AND REFILL THE 4WD TRANSFER CASE FLUID, I HAD THEM COMPLETE THE SERVICE. ALSO DURING MY CARGO DOOR WOULD NOT OPEN NEITHER WOULD THE WINDOW, THEY REPLACED THE LATCH LIFT. THE NEXT PROBLEM WAS THAT I WAS NOTICING SMOKE COMING FROM UNDERNEATH MY HOOD. I BROUGHT THAT TO THEIR ATTENTION AND THEY NOTICE A FLUID LEAK AND HAD TO REPLACE MY CYLINDER HEAD GASKET. THE SMOKE WAS STILL THERE AFTER THAT EFFORT AND NOW MY TRANSMISSION HAS WENT OUT. I NEED AN OVERHAUL TRANSMISSION THAT WILL COST $1800.00 BECAUSE NOW IT'S OUT OF WARRANTY. WHEN I CALLED THE DEALERSHIP THEY MADE IT SEEM AS IF I DID NOT TAKE CARE OF MY VEHICLE. WHEN MY JEEP NEEDS SERVICING I ALWAYS WENT TO THE DEALERSHIP (5 STAR) SO THEY CAN HELP ME TAKE CARE OF MY INVESTMENT. ANY NEEDED REPAIR THAT WAS REQUESTED I HAD DONE. MY JEEP ONLY HAS 57,000 MILES ON IT. THE CRYSLER COMPANY HAS MOST DEFINITELY LOST A CUSTOMER.*AK

I PURCHASED A 2000 JEEP GRAND CHEROKEE LAREDO IN AUGUST 2000. YESTERDAY, MY TRANSMISSION FAILED AND WOULD JERK WHEN SHIFTED INTO REVERSE. TODAY, I CONTACTED THE DEALERSHIP AND WAS BASICALLY TOLD "TOO BAD," BECAUSE MY WARRANTY WAS EXPIRED. I ASKED TO SPEAK TO THE GENTLEMAN THAT SOLD ME THE JEEP, WAS PLACED ON HOLD FOR SEVERAL MINUTES AND THEN TRANSFERRED TO SOMEONE ELSE'S VOICE MAIL. MY JEEP IS 3 YEARS OLD AND HAS 60,000 MILES ON IT (TRANSMISSION FAILURE!!!--I'VE HAD VEHICLES FOR 10 YEARS WITH NO TRANSMISSION PROBLEMS AND THREE TIMES AS MANY MILES). THE BUSINESS MANAGER STATED THAT SHE HAD SEEN VEHICLES WITH 3,000 MILES ON THEM FAIL (BETTER WATCH OUT). THE ESTIMATED COST TO FIX THE TRANSMISSION $1650. I PURCHASED THIS VEHICLE NEW FOR RELIABLE TRANSPORTATION AND HAVE HAD PROBLEMS EVER SINCE. I HAVE ALSO HAD PROBLEMS WITH THE BRAKES AND HAD TO GET THE FRONT ROTORS REPLACED AS THEY WERE WARPED. MY BACK WINDSHIELD WIPER HESITATES BEFORE STARTING. IT IS SOMETIMES HARD TO START AND THAT HAS BEEN HAPPENING SINCE SHORTLY AFTER PURCHASE. STAFF AT THE DEALERSHIPS ARE RUDE AND UNRESPONSIVE WHEN NOTIFIED OF PROBLEMS. STAFF AT THE DEALERSHIP INFORMED ME THAT REPAIRS ON MY JEEP FOR A WIRING PROBLEM WOULD TAKE 3 DAYS, AND THEY ORDERED THE WRONG PARTS AND KEPT MY JEEP FOR OVER 2 WEEKS (AND THEN I HAD TO TAKE IT BACK THE NEXT DAY DUE TO WIRING PROBLEMS). I ALSO HOPE CHRYSLER IS AWARE THAT THEY HAVE JUST LOST A LOYAL JEEP OWNER/FAN. I WILL NEVER PURCHASE ANOTHER JEEP AND WILL CERTAINLY NOT RECOMMEND IT TO ANYONE.

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.

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.
