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.

HEARD A NOISE COMING FROM THE REAR OF THE CAR TOOK IT INTO THE SHOP AND WAS TOLD THAT IT WAS THE REAR DIFFERENTIAL, AND I WAS ALSO INFORMED THAT MY TRANSMISSION WAS SLIPPING IN 1ST & 2ND GEAR. I HAD THE DIFFERENTIAL REPAIRED AND THE TRANSMISSION SERVICED. WE GOT SNOW THIS YEAR WHERE YOU WOULD NEED THE 4 WHEEL DRIVE, WELL BEING I NEVER HAD THE NEED TO USE THE 4 WHEEL DRIVE MODE I WAS SURPRISED TO FIND OUT THAT MINE DIDN'T WORK. TOOK IT INTO THE SHOP AND WAS TOLD THAT THE TRANSFER CASING AND TRANSMISSION NEED TO BE REPLACED. SO I TOOK IT TO THE DEALER I BOUGHT THE JEEP FROM. I LET THEM REPAIR MY TRANSFER CASING AND WAS TOLD BECAUSE I DIDN'T HAVE THE EXACT SAME TIRES ON THE VEHICLE THAT IS WHAT CAUSED THE TRANSFER CASING TO FAIL. THE TIRES WERE THE SAME SIZE ON THE FRONT AND REAR JUST DIFFERENT BRANDS. THEY TOLD ME THAT I DIDN'T HAVE A PROBLEM WITH THE TRANSMISSION. I THEN PICKED THE JEEP UP AND THE ROARING SOUND CAME BACK SO I TOOK IT TO THE DEALER TO SEE WHAT THEY THOUGHT THE NOISE WAS I WAS TOLD AT THAT TIME THAT MY FRONT DIFFERENTIAL WAS BAD AND NEEDED TO BE REPAIRED AND THAT THE REAR DIFFERENTIAL WAS ALSO BAD, BUT BEING I HAD THAT WORK DONE AT A INDEPENDENT SHOP I HAD TO TAKE IT BACK TO THEM TO FIX THE REAR AND THEN TOOK THE JEEP BACK TO THE DEALER TO HAVE THEM DO THE WORK ON THE FRONT. I AM IN THE PROCESS OF TAKING THE JEEP BACK TO THE DEALERSHIP BECAUSE MY JEEP IS NOW PULLING TO THE RIGHT. I WAS ABLE TO DRIVE MY JEEP FOR A WEEK. I REALLY HAVE NOT HAD MY JEEP SINCE JANUARY I REALLY THINK THAT DAIMLER CHRYSLER KNOWS THERE IS A PROBLEM WITH THE 1998 JEEP GRAND CHEROKEE AND I HOPE THAT SOMETHING WILL BE DONE ABOUT. *JB

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.
Remedy: DEALERS WILL INSPECT THE TRANSMISSION FOR LEAKAGE AT THE FILL TUBE GROMMET SEAL. IF NO LEAK IS DETECTED, A NEW FILL TUBE GROMMET SEAL AND WATER DEFLECTOR SHIELD WILL BE INSTALLED, AND PROPER ALIGNMENT OF THE FILL TUBE VERIFIED. IF THE PRESENCE OF A LEAK IS DETECTED, THE VEHICLE WILL BE EVALUATED FOR SHUDDER DURING TORQUE CONVERTER ENGAGEMENT. IF NO SHUDDER IS DETECTED, THE TRANSMISSION WILL BE TRIPLE FLUSHED, AND NEW FILL TUBE GROMMET SEAL AND WATER DEFLECTOR WILL BE INSTALLED AND PROPER ALIGNMENT OF THE FILL TUBE VERIFIED. IF SHUDDER IS DETECTED, THE TORQUE CONVERTER WILL BE REPLACED, A NEW FILL TUBE GROMMET SEAL AND WATER DEFLECTOR WILL BE INSTALLED, AND PROPER ALIGNMENT OF THE FILL TUBE VERIFIED. THE RECALL BEGAN ON OCTOBER 31, 2005. OWNERS MAY CONTACT DAIMLERCHRYSLER AT 1-800-853-1403.

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.
