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.

MY JGC HAS HAD OFF AND ON PROBLEMS SINCE I BOUGHT IT VIRTUALLY. NOT BEING A PARTICULARLY COMPLAINT ORIENTED PERSON, I AT FIRST ATTRIBUTED THE TRANSMISSION PROBLEM ON THIS TRUCK TO THE FACT THAT I HAD NEVER OWNED A 4WD VEHICLE BEFORE. FROM THE OUTSET THIS TRUCK SHUDDERED WHEN IN A TIGHT TURN, EITHER DIRECTION. DURING THE FIRST WINTER II OWNED IT, I LEFT IT IN MY DRIVEWAY IN PARK ONLY TO COME OUT LATER TO FIND IT AT THE END OF MY DRIVE. THIS HAPPENED A NUMBER OF TIMES, ONCE STOPPING ONLY BECAUSE IT STOPPED UP AGAINST MY WIFE'S CAR. I THOUGHT I WAS CRAZY AT FIRST--NOW I WON'T LEAVE THIS VEHICLE ON A FLAT SURFACE WITHOUT THE EMERGENCY BRAKE ON. RECENTLY, THE TRUCK DEVELOPED A HUGE, AND FRIGHTENING "CLUNK" BETWEEN 2ND AND 3RD GEAR I BELIEVE. AGAIN, I DID NOT MAKE MUCH OF THIS UNTIL THE "CHECK ENGINE" LIGHT CAME ON MORE OR LESS PERMANENTLY. THE TRUCK WILL NO LONGER SHIFT INTO APPROPRIATE GEAR, HAS POOR ACCELERATION AND WORSENING GAS MILAGE, AND RUNS AT ERRATIC AT BEST RPMS. I HAVE TAKEN IT TOO THE DEALER WHO ON THE FIRST VISIT TOLD ME THEY COULDN'T REPRODUCE THE PROBLEM AND TOLD ME TO BRING IT BACK WHEN IT HAPPENED AGAIN. IT HAPPENED AGAIN ON THE WAY OUT THE LOT. I TOOK THE TRUCK BACK ABOUT A WEEK LATER AND WAS TOLD IT WOULD COST ABOUT $250 TO DIAGNOSE THE PROBLEM. A WEEK LATER, I TOOK IT BACK TO THE DEALER, ANGRY THAT I HAD FOUND MY EXACT PROBLEM ON A TECHNICAL SERVICE BULLITEN FROM CHRYSLER ITSELF. THE DEALER ALTHOGH VERY NICE BASICALLY TOLD ME I WOULD HAVE TO PAY TO HAVE THE TRANSMISSION REPLACED AT A COST OF SOME (AT LEAST) $3,000.00. I AM TAKING THE CAR BACK NEXT WEEK TO HAVE THE DEALER TEAR DOWN THE TRANSMISSION, AFTER HAVING ATTEMPTED TO SPEAK TO THE DISTRICT MANAGER, WHO MYSTERIOUSLY DISAPPEARRED UPON MY ARRIVAL. HAVING READ NOW VIRTUALLY IDENTICAL COMPLAINTS TO MINE ON THIS INTERNET SIGHT, I AM NOW TORN BETWEEN LETTING THEM REPAIR IT TO WHAT SEEMS LIKE NO AVAIL , FILING A LAWSUIT, OR TRADING THE VEHICLE IN AND LOSING A TON OF MONEY. THANK YOU FOR YOUR TIME.*AK

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.

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.
