Mileage at the reported incident
Limited mileage data: 343 of 1,919 reports include usable mileage. There isn’t enough coverage to show a useful chart.
NHTSA’s mileage field refers to the reported incident, not necessarily the filing date. This shows report counts, not the likelihood of a failure.

WHEN SHIFTING FROM PARK TO ANY OTHER GEAR, THE TRANSMISSION MAKES A LOUD CLUNKING SOUND , ALONG WITH A "MOAN" WHICH CONTINUES UNTIL I TAKE MY FOOT TOTALLY OFF THE BRAKE. NEVER HAVE A PROBLEM WHILE VEHICLE IS UNDERWAY. TAKEN TO DEALER TWICE AND TOLD THAT THIS IS NORMAL FOR AN ELECTRONIC TRANSMISSION. I HAVE HAD "LESSER" VEHICLES WITH OVER 100,000 MILES ON THEM AND THEY NEVER MADE SUCH NOISES. PEOPLE ACTUALLY TURN AND LOOK TOWARD MY VEHICLE IF I HAPPEN TO BE IN A POPULATED AREA AND NEED TO SHIFT THE AUTOMOBILE. TO SAY THE LEAST, IT IS ANNOYING AND EMBARASSING.*AK
VEHICLE WILL JUMP OUT OF PARK GEAR INTO REVERSE WHILE IDLING. CONSUMER HAS EMERGENCY PARKING BRAKE APPLIED, AND VEHICLE WAS UNABLE TO MOVE. DEALERSHIP HAS EXAMINED VEHICLE TWICE, AND WAS UNABLE TO DETERMINE A CAUSE OF THE PROBLEM. PLEASE PROVIDE ANY ADDITIONAL INFORMATION / ATTACHMENTS.*AK

IN APRIL OF THIS YEAR, WHILE PULLING OUT OF MY GARAGE, I PUT MY CAR INTO PARK WHILE IT WAS RUNNING, TO MOVE A TOY BEHIND MY VEHICLE. I EXITED THE VEHICLE AND PROCEEDED TO GO TO REMOVE THE TOY WHEN I REALIZED THE VEHICLE WAS NOW MOVING. I MADE ONE ATTEMPT TO GET BACK IN, NEARLY SLIPPING UNDER IT AND MADE A SECOND ATTEMPT THIS TIME SUCCEEDING BUT NOT BEFORE THE DOOR HAD CAUGHT ONTO THE CORNER OF MY HUSBANDS COMPRESSOR CAUSEING $2700.00 WORTH OF DAMAGE. I NOTIFIED THE DEALER, THEY CHECKED FOR A CAUSE, FOUND NOTHING. SHORTLY AFTER, ALL THE REPORTS OF THIS PROBLEM SURFACED IN THE MEDIA. I CONTACTED CHRYSLER AND THEY CLAIM THAT ONLY THE YEARS FROM 1995 TO 1999 ARE AFFECTED. HAS THE CAUSE OF THE PROBLEM BEEN RECTIFIED IN THE 2001'S OR DO WE NEED MORE DEATHS FOR THEM TO ACKNOWLEDGE THE PROBLEM. I HAVE SUFFERED A $500.00 LOSS AND A THREE YEAR SURCHARGE ON MY INSURANCE, LOSS OF MERIT RATING AND STILL HAVE A FEAR OF POSSIBLE INJURY WITH THIS VEHICLE.

Sep 14, 2005
ON CERTAIN SPORT UTILITY VEHICLES EQUIPPED WITH 3.7L ENGINES AND NAG1 AUTOMATIC TRANSMISSIONS, THE AIR CONDITIONER EVAPORATOR CONDENSATE WATER MAY ENTER THE TRANSMISSION AT THE FILL TUBE GROMMET SEAL. THIS CAN RESULT IN SHUDDER DURING TORQUE CONVERTER CLUTCH ENGAGEMENT.
Consequence & remedy
Consequence: IT CAN LEAD TO INCREASED TRANSMISSION OPERATING TEMPERATURES, BOILING OF THE WATER, AND A SUBSEQUENT PURGING OF TRANSMISSION FLUID INTO THE ENGINE COMPARTMENT POTENTIALLY RESULTING IN AN UNDERHOOD FIRE.

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.
