WHEN ACCELERATING FROM A STOPPED POSITION, VEHICLE FEELS SLUGGISH, AS THOUGH IT IS STARTING FROM SECOND OR THIRD GEAR. WHEN STOPPING, A LOUD CLUNKING NOISE IS HEARD. ROUGH AND ERRATIC SHIFTING IS FELT AS THE TRANSMISSION DOWNSHIFTS. WITH A VEHICLE WITH LESS THAN 27,000 MILES ON IT, THE TRANSMISSION DOES NOT SEEM TO BE WORKING NORMALLY (AT LEAST AS NORMAL AS ANY OTHER AUTOMATIC TRANSMISSIONS I HAVE HAD OVER THE YEARS). I HAVE READ SEVERAL OTHER COMPLAINTS POSTED THAT EXPRESS SIMILAR PROBLEMS, BUT HAVE NOT SEEN ANY RESOLUTION FROM JEEP OTHER THAN TELLING THEIR CUSTOMERS THAT THIS IS NORMAL OPERATION. THIS TROUBLES ME AND DOES NOT GIVE ME MUCH CONFIDENCE IN THEIR ABILITY TO TROUBLESHOOT THE PROBLEM. I WANT A RECORD OF THE PROBLEM FOR FUTURE REFERENCE. *LA

PURCHASED A JEEP GRAND CEHROKEE LAST OCTOBER. IN DECEMBER I HAD TO HAVE THE ROTORS REPLACED WITHIN 1,000 MILES OF THE ORIGINAL REPLACEMENT, THE ROTORS WARPED AGAIN. I REPLACED THE ROTORS AGAIN IN MARCH, BY JULY THE ROTORS HAD ONCE AGAIN WARPED. THE BRAKE COMPANY WHO REPLACED THE ROTORS BOTH TIMES WITH NEW FACTORY PARTS WILL NOT AWARD THE WARANTY OF THE ROTORS. THEY SAID IT IS A PROBLEM WITH THE 1999 JEEP GRAND CHEROKEES AND NOT THEIR PRODUCTS. I AM FORCED TO AGAIN PAY TO HAVE THE ROTORS REPLACED. THIS IS THE THIRD TIME IN LESS THEN A YEAR. I HAVE NEVER HAD THIS PROBLEM WITH ANOTHER VEHICLE I HAVE OWNED. IN ADDITION, THE CAR EXHIBITS A "STOP AND BUMP" EVERY TIME THE VEHICLE COMES TO A STOP. I HAVE SEEN THIS PROBLEM ADDRESSED WITH THE DRIVE SHAFTS, BUT APPARENTLY EVEN REPLACING THIS PART, DOES NOT CAUSE THE VEHICLE TO STOP THIS BEHAVIOR. LASTLY, THE VEHICLE IS HARD TO SHIFT FROM SECOND TO THIRD GEARS. I DID NOT EXPECT TO HAVE THIS MANY PROBLEMS WITH A VEHICLE FIRST OF ALL THAT COSTS THIS MUCH AND SECONDLY THAT IS SO NEW. I AM EXTREMELY DISSAPPOINTED. *LA

I HAVE CONTACTED JEEP AND THE LOCAL DEALER ABOUT THIS ISSUE AND THEY ARE NOT WILLING TO STEP FORWARD ON THIS ISSUE. THE VEHICLE HAS 30,K MILES AND IS A 3RD VEHICLE FOR ME TO USE, SO IT DOES NOT GET A LOT OF USUAGE. AT THIS POINT I WOULD CONSIDER THIS A COMPLAINT ISSUE AS THE VEHICLE IS IN IMMACULATE CONDITION, EXCEPT FOR THE LEAKING TRANSMISSION. I WOULD LIKE TO INQUIRE AS TO THE NUMBER OF '99 JEEPS THAT ARE EXPERIENCING THE SAME ISSUE. I HAVE BEEN COMMUNICATING WITH OTHER JEEP OWNERS THAT HAVE THE EXACT SAME ISSUE. I HAVE ENCOURAGED THEM TO DO THE SAME AS I AM WITH MY FILED COMPLAINT. ALSO, JEEP HAS BEEN EXTREMELY ARROGANT ABOUT THEIR RESPONSES TO "NOT ASSIST" WITH THIS MATTER.

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.

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.
