What 1,637 owners told NHTSA about the 2012 Jeep Grand Cherokee Srt

IN A PULL FORWARD PARK SPOT, SHIFTED TO REVERSE TO BACK OUT. CAR LURCHED BACKWARD VERY FAST. CROSSED THE ROAD, STOPPED BY A 4' X 6' POST SET IN THE GROUND. THE COLLISION BROKE THE POST AND CRACKED MY CAR'S REAR BUMPER. I PUT MY FOOT ON THE BRAKE, BUT IT COULD NOT CONTROL THE SPEED. THANKFULLY, NO PEOPLE WERE IN THE ROAD. NO INJURIES. THIS WAS PIN A COMMERCIAL FARM, WHERE PEOPLE CAN HARVEST THE FRUITS AND VEGETABLES. THE ROAD IS BLACKTOP. MY CAR LEFT SKID MARKS ACROSS THE WIDTH OF THE ROAD. IT WAS A FRIGHTENING EVENT FOR ME AND MY FRIEND. I CALLED MY CAR DEALER LATER TO ASK IF THERE HAD BEEN ANY INCIDENTS LIKE THIS...SHIFTING INTO REVERSE AND THE CAR ZIPPED OFF- OUT OF CONTROL. TECH SAID ' NO'.

180 AMP ALTERNATOR EXPERIENCED CATASTROPHIC FAILURE CAUSING TOTAL LOSS OF ALL POWER, BATTERY FAILURE, PCM FAILURE AND SMOKING AND BURNING SMELL FROM ENGINE COMPARTMENT. EXPERIENCED LOUD WHINNING FROM ALTERNATOR WHILE DRIVING IMMEDIATELY PRIOR TO FAILURE. ULTIMATE FAILURE OCCURED AS CAR PULLED INTO PARKING SPOT. THIS IS THE SAME ISSUE EXPERIENCED BY 160 AMP ALTERNATOR UNDER RECALL. IT IS EXTREMELY DANGEROUS AND CHRYSLER/JEEP SHOULD BE REQUIRED TO FIX THESE ISSUES.

ISSUE: TRANSMISSION FAULT LEADS TO UNEXPECTED "CREEP MODE" IN DRIVE, OVER-PRESSURIZED TRANS EXPELS TRANS FLUID ONTO MANIFOLD LEADING TO ENGINE FIRE. DETAILS: WHEN STOPPED & IDLING IN DRIVE FOR PERIOD OF TIME, TRANSMISSION GOES INTO CREEP MODE OF SOME SORT & WHEN TRYING TO ACCELERATE FROM STOP IT DOES NOT MOVE. THIS CAN HAPPEN AT A LEFT-TURN RED-LIGHT AND WHEN LEAST EXPECTED, HAVING DISASTROUS RESULTS. TRANSMISSION FAILURE FROM OVER-PRESSURIZATION ALREADY LED TO TRANS FLUID BEING EXPELLED FROM DIPSTICK TUBE ONTO ENGINE MANIFOLD RESULTING IN AN ENGINE FIRE. OWNER WAS EASILY ABLE TO REPLICATE THE PROBLEM BY SITTING IN DRIVE FOR 7-8 MINUTES & THEN ATTEMPTING TO ACCELERATE. VIDEOTAPED EVIDENCE SHOWS THE TRANS IS AT NORMAL OPERATING TEMP, YET TACHOMETER IS SHOOTING UP TO 25,000RPM'S & CAR ONLY CREEPS FORWARD. AT THAT MOMENT SMOKE BEGAN POURING OUT FROM UNDER THE VEHICLE AS ONCE AGAIN FLUID WAS BEING EXPELLED ONTO MANIFOLD. ONLY THIS TIME OWNER DID NOT OPEN THE HOOD SO THE LACK OF INFLUX OF FRESH O2 DID NOT IGNITE FLUID LIKE IT DID THE FIRST TIME. VEHICLE IS UNDER 100,000 MILE DRIVETRAIN WARRANTY & JEEP DEALER ENTERED DIAGNOSIS AND REQUEST TO "REPLACE TRANSMISSION, COOLER, O2 SENSOR, & WIRING HARNESS" WHICH FCA USA, LLC REJECTED. FCA RREFUSES TO SAY WHY. DEALER HAS HELD VEHICLE NOW FOR 2MONTHS & 2WEEKS WHILE DEALER TRIES TO CONVINCE FCA TO REPLACE DEFECTIVE DRIVETRAIN. FCA REFUSES TO SUPPLY WRITTEN DOCUMENTATION OF WHY CLAIM IS BEING REJECTED. FCA SENT OUT A "SPECIAL INVESTIGATOR" (FOR FIRES) WHO WITHOUT MEETING THE SERVICE MGR OR AUTHORIZED DRIVETRAIN TECH, SERVE DETERMINES IT IS NOT UNDER WARRANTY. YET HE KNOWS NOTHING OF TRANSMISSIONS & SPOKE TO NO ONE AT DEALER ABOUT THEIR DIAGNOSIS AND ISSUE. VEHICLE IS UNSAFE AS IT WILL FAIL TO ACCELERATE WITHOUT NOTICE AT ANYTIME & CONTINUED EXPOSURE TO OVER-PRESSURIZED TRANSMISSION AND EXPELLED TRANS FLUID COULD RESULT IN FIRE. *TR

TO WHOM IT MAY CONCERN: I WOULD LIKE TO FORMALLY REPORT WHAT I CONSIDER A CRITICAL FLAW WITH MY 2012 9JEEP GRAND CHEROKEE EQUIPPED WITH THE PENTASTAR V6 ENGINE. I HAVE HAD MULTIPLE INSTANCES OF UNINTENDED ACCELERATION BY THE ENGINE IN THE PAST 45 DAYS. THE MOST RECENT EVENT RESULTED IN MY DAMAGING VEHICLE'S WHEEL AS WELL AS NEARLY HITTING A PARKED VEHICLE. I HAVE 85533 MILES ON MY CAR AND THIS FLAW HAS ONLY MANIFESTED ITSELF IN THE PAST 3 DAYS (85533MILES). I HAVE CONTACTED MY LOCAL DEALER CONCERNING THIS ISSUE, BUT HAVE BEEN TOLD THAT IN ORDER TO LOOK INTO THIS OBVIOUS SAFETY DEFECT, I AM REQUIRED TO PAY FOR THEIR DIAGNOSTIC TIME. I FEEL THAT THE MANUFACTURER OF A PRODUCT THAT HAS SUCH A BLATANT SAFETY RISK SHOULD BE APPRECIATIVE OF BEING INFORMED OF SUCH A DEFECT, AND CERTAINLY TAKE RESPONSIBILITY FOR IT. SINCERELY, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

PREPARING TO BACK FROM MY GARAGE, I STEPPED ON THE BRAKE AND PLACED THE SELECTOR IN REVERSE. DESPITE MY HOLDING FIRMLY ON THE BRAKE, THE JEEP GRAND CHEROKEE MOVED BACKWARDS AS IF SLIDING ON ICE. IT COLLIDED, AT A SLOW SPEED, WITH A CAR PARKED OPPOSITE ON THE DRIVEWAY. WHILE CONTINUING TO APPLY THE BRAKE, I MOVED THE SELECTOR INTO DRIVE IN ORDER TO PULL FORWARD AWAY FROM THE OTHER VEHICLE. THE JEEP LUNGED FORWARD WITH THE FRONT TIRES REMAINING STATIONARY AND SLIDING ALONG THE GROUND. THE VEHICLE CRASHED INTO THE STONE COLUMN BETWEEN THE TWO GARAGE DOORS. THE CAR WAS DAMAGED TO THE EXTENT OF AT LEAST $5,700. THERE WAS DAMAGE TO THE BUILDING AND TO ONE OF THE GARAGE DOORS. I AM FEARFUL OF DRIVING THE JEEP GRAND CHEROKEE EVEN AFTER REPAIRS ARE COMPLETED. IF I HAD BEEN IN A PARKING LOT OR AT A STOP LIGHT THERE COULD HAVE BEEN SEVERE DAMAGE OR INJURY FROM THIS INCIDENT. *TR
