What 481 owners told NHTSA about the 2011 Jeep Wrangler Unlimited 392

TRANSMISSION IS A STANDARD SHIFT WHEN I LET OUT ON CLUTCH THE ENGINE WILL STALL. AT FIRST I THOUGHT BECAUSE I WAS NOT LETTING OUT ON CLUTCH PROPERLY AND HAD TO GET USED TO DRIVING IT.MY BOY FRIEND WHO DRIVES A DIESEL TRUCK WITH A STANDARD EVERYDAY HAD THE INCIDENT HAPPEN TO HIM AND SUGGESTED WE TAKE IT IN FOR SERVICE .WHICH THEY SAID THEY TEST DROVE AND CONCLUDED NO PROBLEMS MANY TIMES BACK TO DEALERSHIP WITH NO LUCK NOW I'M OUT OF WARRANTY. THE VEHICLE IS VERY DANGEROUS IT STALLS ALL THE TIME WHEN I SIT AND IDLE AT A RED LIGHT OR A CROSS ROAD AT A STOP SIGN WHEN I LET OUT ON CLUTCH IT STARTS ROLLING FINE WHEN CLUTCH IS DISENGAGED IT WILL NOT TAKE THE GAS THEN ENGINE WILL SPUTTER THEN DIE. CAN SOMEONE FROM YOUR AGENCY TEST MY JEEP PLEASE IT IS GOING TO CAUSE ME TO GET INTO A WRECK. I LIVE IN MOBILE ALABAMA. *TR

I USE MY JEEP OFF ROADING ONCE IN A WHILE, EVERYTIME I GET OFF INTO SAND WHETHER ITS HARD PACKED OR SOFT MY TRANSMISSION OVER TEMP LIGHT COMES ON. THE FIRST TIME I HAD THIS HAPPEN I STOOPED AND READ THE OWNERS MANUAL ON WHAT CAUSES THIS LIGHT AND WHAT ACTIONS TO TAKE TO CORRECT IT. THE MANUAL SAYS TO IMMEDIATELY STOP THE CAR AND TURN IT OFF, WHICH IS RIDICULOUS OUT IN THE MIDDLE OF NOWHERE. I RESEARCHED THIS ISSUE AND FOUND THAT THE TRANSMISSION FLUID MAY OVERHEAT AND START A FIRE AS IT SPEWS OUT THE DIP STICK TUBE. THIS IS CRAZY, WHY DID THEY NOT PUT A TRANSMISSION COOLER ON THIS CAR. I HAVE HAD 7 OTHER WRANGLERS OVER THE YEARS AND HAVE NOT HAD THIS ISSUE OR THREAT OF A FIRE BEFORE. STOPPING YOUR CAR TO PREVENT A FIRE SHOULD NOT BE AN IDIOT LIGHT, IT NEEDS AN ENGINEERING FIX. *TR

SHIFTING THE 4-WHEEL DRIVE TRANSFER CASE (TC) FROM 2HI TO 4HI OR 4LOW (OR IN REVERSE ORDER) CAN CAUSE THE TRANSFER CASE SHIFTING CABLE (TCSC) (MOPAR PART 52060462AG) TO FAIL AND BECOME DISCONNECTED FROM EITHER THE TC OR THE SHIFT LEVER IN THE CAB (OR BOTH). THE PART?S PLASTIC COMPONENTS ARE INHERENTLY TOO WEAK TO WITHSTAND NORMAL USE. SAFETY RISKS WHICH CAN ARISE UPON COMPONENT FAILURE, IF THE VEHICLE OWNER AND THEIR FAMILY (CHILDREN) ARE AT A LOCATION AND/OR TERRAIN WHERE THE VEHICLE IS DESIGNED/MARKETED FOR TRAVEL (WHETHER BY RECREATION OR NECESSITY), AND THE LOCATION/TERRAIN IS: (I) SUBJECT TO INCLEMENT WEATHER (E.G. SNOW, ICE, FLOODING, EXTREME HEAT); OR (II) ON AN EXTREME INCLINE WHICH IS UNSAFE TO NEGOTIATE WITHOUT 4WD; OR (III) ANY CIRCUMSTANCE WHICH REQUIRES 4WD TO NAVIGATE TO A SAFE LOCATION; OR (IV) THE TCSC FAILS WHEN THE TC BECOMES STUCK IN THE NEUTRAL POSITION WHILE SHIFTING, AND IS UNABLE TO ESCAPE IMPENDING HARM (FLASH FLOOD) ... THERE IS OBVIOUS RISK TO LIFE/SAFETY. THE OWNER HAS A RIGHT TO RELY ON THE COMPONENTS AND REASONABLE SAFETY PERFORMANCE FOR WHICH THE PRODUCT IS DESIGNED/MARKETED. JEEP IS AWARE OF THE ISSUE, AND THE MANUAL FAILS TO CITE THIS AS A POSSIBLE CATASTROPHIC EVENT, LEAVING THE UNSUSPECTING OWNER AT A LOSS IN AN EMERGENCY SITUATION. IT IS NOT REASONABLE FOR THIS COMPONENT TO FAIL WITHIN A FEW THOUSAND MILES AS REPORTED BY JEEP OWNERS. ADVANCE ADAPTERS (WWW.ADVANCEADAPTERS.COM) MANUFACTURES A TCSC WHICH MEETS THE CRITERIA (PRODUCT# 715596) REQUIRED FOR THIS COMPONENT. THERE IS NO REASON THAT JEEP CANNOT DO THE SAME AND/OR CONTRACT WITH ADVANCE ADAPTORS TO SUPPLY THE PART TO JEEP OWNERS. WE URGE NHTSA?S INVESTIGATION OF THIS SAFETY DEFECT AND JEEP WILL REDESIGN THE DEFECTIVE PART AND ISSUE A RECALL FOR AFFECTED VEHICLES ON WHICH THE PART WAS INSTALLED AS OEM AND TO EXTEND THE WARRANTY TO REPLACEMENT FOR LIFE OF THE VEHICLE. *TR

AFTER SHIFTING FROM 4 WHEEL DRIVE TO 2 WHEEL DRIVE, THE VEHICLE REMAINED IN 4 WHEEL DRIVE AT ALL SPEEDS. THIS RESULTED IN A REDUCED STEERING RANGE AND, I BELIEVE, IMPAIRED THE VEHICLE IN AN AVOIDANCE SITUATION. THIS WAS ESPECIALLY NOTICED AT SLOW SPEED. THE JEEP DEALER FOUND A DISCONNECTED 4 WHEEL DRIVE ACTUATOR CABLE TO THE TRANSMISSION. A NEW REPLACEMENT BUSHING WAS INSTALLED AT THE TRANSMISSION. THE DEALER INDICATED THAT THE REPLACEMENT PART MAY HAVE BEEN IMPROVED BECAUSE IT DID NOT HAVE THE SAME PART NUMBER AS THE ORIGINAL. *TR

NHTSA ODI 10373705

I OWN A 2011 JEEP WRANGLER WITH A MANUAL TRANSMISSION. IN COLD WEATHER AND WITH THE VEHICLE COLD, FOURTH GEAR CONTINUALLY POPS OUT OF GEAR AND NOW 2ND IS STARTING TO DO IT. I BROUGHT IT TO THE DEALERSHIP, BUT THEY COULD NOT DUPLICATE THE PROBLEM. ALSO, THEY CHECKED THE TSB, BUT NONE ARE LISTED. I HAVE READ JEEP FORUMS AND LEARNED THAT SOME BELIEVE THE PROBLEM WITH THE 2011S IS THE BOOT, EITHER INNER OR OUTER OR BOTH. WHEN IT IS COLD OUTSIDE, THE BOOTS DON'T FLEX WELL--SO IT PUSHES THE VEHICLE OUT OF GEAR. I HAVE BEEN IN THE MIDDLE OF A TURN AND IT HAPPENS--HUGE SAFETY ISSUE. *TR
