IN THE EVENING, JUNE 13TH, 2001, MY VEHICLE WAS PARALLEL PARKED ON A SIDE STREET IN BOSTON, MY PARTNER SHIFTED THE AUTOMATIC TRANSMISSION INTO REVERSE, BACKED UP APPROXIMATELY 2 FEET, I WAS ON THE SIDEWALK GUIDING HIM BACK SO AS TO NOT HIT THE CAR BEHIND US. WITH HIS FOOT FIRMLY ON THE BRAKE, HE SHIFTED INTO DRIVE, SUDDENLY THE ENGINE REVVED HIGH, AND THE VEHICLE LUNGED FORWARD, STRIKING A TOYOTA RAV4 PARKED IN FRONT. MY BUMPER GUARD HIT THEIR BUMPER HARD AND MY GRILL LIGHTLY HIT THEIR REAR MOUNTED SPARE TIRE, BUT THERE WAS REALLY NO DAMAGE. WITHIN A COUPLE OF SECONDS THE ENGINE IDLE RETURNED TO NORMAL. ONCE THE VEHICLE WAS OUT OF THE PARKING SPACE, YOU COULD SEE TIRE SKID MARKS APPROX. 3 FEET LONG FROM THE FRONT TIRES, AND THE HEAVY SMELL OF "BURNT" RUBBER. AFTER READING ABOUT THE GRAND CHEROKEE PROBLEM TODAY, 08-03-01, IT MADE ME REALIZE THAT IF A PERSON WERE STANDING BETWEEN THE VEHICLES ON THE DAY OF MY INCIDENT, THEY WOULD HAVE BEEN CRUSHED BADLY. I BROUGHT IT TO THE DEALER THE FOLLOWING WEEK , THEY SAID "THEY COULD NOT DUPLICATE THE PROBLEM AND COULDN'T DETECT ANYTHING WRONG." THE PROBLEM HAS NOT RE-OCCURED, BUT SHORTLY AFTER THEY NEEDED TO REPLACE THE WIRING HARNESS FOR THE GUAGES SINCE THEY WOULD ALL GO OFF WHILE I WAS DRIVING, AND THE ODOMETER INDICATED "NO BUS" I SUSPECT THE TWO ARE UNRELATED, BUT I'M NOT AN EXPERT. THE DEALER KNEW EXACTLY WHAT WAS WRONG WITH THE GUAGES, BUT NEVER HAD ANOTHER REPORT OF THE ENGINE REVVING OUT OF CONTROL AS MINE DID. THANKS FOR YOUR TIME. REGARDS, AL FOWLER. *AK

ON 09/07/99 AS MY JEEP WRANGLER WAS PARKED IN THE PARKING LOT OF MY BANK IT PROCEEDED TO ROLL BACKWARDS OUT OF THE PARKING LOT, ACROSS A BUSY STREET, AND INTO A CANAL ( DITCH). IT LANDED ON ITS RIGHT SIDE AND WAS SUBMERSED. IT TOOK TWO TOW TRUCKS AND 3 HOURS TO PULL IT OUT. ONCE AT THE JEEP DEALERSHIP THEY INVESTIGATED TO SEE WHAT HAD HAPPENED. THEY CAME TO THE CONCLUSION THAT IT WAS THE GEAR SHIFT ( WHICH HAD BEEN IN THE PARKED POSITION) BUT NEVER GAVE ANY SPECIFICS. MY INSURANCE AND I ENDED UP PAYING A TOTAL OF ABOUT $9,000 DOLLARS. THE REPAIRS TOOK A MONTH AND A HALF, IN WHICH MY INSURANCE PAID FOR A RENTAL CAR. WHEN I ASKED ABOUT HAVING THE POWERTRAIN INVESTIGATED BY AN OUTSIDE MECHANIC THEY OFFERED TO "SELL" IT TO ME FOR $1000 DOLLARS. I FILED A COMPLAINT WITH THE MANUFACTURER SHORTLY THEREAFTER, AND NEVER TO THIS DAY HAVE RECEIVED A REPLY. AFTER READING THE ARTCILE IN THE NEWSPAPER TODAY ABOUT THE DEFECTS IN THE GRAND CHEROKEES IT MADE ME THINK ABOUT MY JEEP AND WHAT HAPPENED TO ME. THE SITUATIONS WITH OTHERS WAS EXACTLY LIKE MY EXPERIENCE EXCEPT THAT NO ONE WAS INJURED. PLEASE INVESTIGATE THE WRANGLERS YEARS 1995-1999 ALSO FOR SIMILAR ACCIDENTS. THAT JEEP WAS MY FIRST VECHICLE AFTER GRADUATING COLLEGE, I HAD ALWAYS WANTED ONE. IT WAS THE FIRST AND WILL BE THE LAST JEEP I EVER OWN AFTER THAT HORRIBLE EXPERIENCE. I AM JUST SO THANKFUL THAT NO ONE WAS INJURED.*AK

Opened Mar 28, 2012 · Closed Aug 7, 2012

Status: closed (inferred from source dates) · Engine And Engine Cooling; Power Train:automatic Transmission

In a letter dated May 15, 2012, the Chrysler Group LLC (Chrysler) submitted a Defect Information Report to NHTSA identifying a safety defect regarding fires originating between the transmission skid plate and the exhaust catalyst in approximately 65,246 model year (MY) 2010 Jeep Wrangler 4x4 vehicles with automatic transmissions (NHTSA Recall 12V-216).According to Chrysler, changes to the exhaust system for MY 2010 resulted in reduced clearances between the exhaust catalyst and the skid plate.If debris collects in the area of the skid plate and is not removed, there is an increased potential for underbody debris fires.ODI's analysis of skid plate area fires in the MY 2010 Wrangler vehicles with automatic transmissions found that the rate increased significantly from approximately 1.7 fires per 100,000 vehicle years in the MY 2007 through 2009 vehicles with the prior exhaust design to approximately 14.8 fires per 100,000 vehicle years in MY 2010 vehicles, a nearly 800 percent increase.In analysis of both Vehicle Owner Questionnaire (VOQ) data submitted to the Office of Defects Investigation (ODI) and Chrysler's consumer complaint data submitted to ODI, 35 unique reports were identified by Chrysler alleging fire in subject vehicles with origins near the engine compartment or in the underbody area directly beneath and to the rear of the engine compartment.Chrysler's assessments of the 35 reports of fire were categorized by likely causes.Eleven of the fires were determined to be caused by skid plate debris accumulation and 4 additional fires were found to have originated in the area of the skid plate, but debris ignition could not be confirmed.An additional skid plate debris fire was reported to ODI after the recall announcement, bringing the total known fire count to 36, including 12 caused by skid plate debris and 4 originating in the skid plate area from unknown causes.Chrysler identified a design change to the exhaust system in MY 2010 that increased the possibility of debris contact with an exhaust catalyst.Beginning in MY 2011, the skid plate was replaced with a skid bar for weight reduction purposes.The skid bar having a much smaller surface area than the skid plate reduces the potential for debris entrapment.The recall remedy for recall 12V-216 will involve replacement of the skid plate with the skid bar.As background, the MY 2010 subject vehicles are a part of the JK generation of Jeep Wrangler vehicles that began production in MY 2007.Chrysler conducted a prior recall (09V-436) of MY 2007 and 2008 Jeep Wranglers for a defect involving overheated transmission fluid expulsion that could contact the exhaust and cause an engine compartment fire.The recall remedy was to add audible (chime) and visual warnings (hot oil message in the instrument cluster) to alert the driver that the vehicle was being operated with elevated transmission fluid temperatures.Chrysler enhanced the audible warning with a service campaign (J31) for MY 2009 and a portion of the subject MY 2010 vehicles.Transmission fluid expulsion has not been identified as the cause of any of the 36 fire incidents in the subject vehicles. No indications of a common causal pattern were evident in the remaining 20 fire incidents in the subject vehicles.Six (6) of the incidents appear to be related to improper wiring of various added aftermarket equipment, 2 appear to be related to improper oil change, 1 was related to a damaged transfer case, 1 was related to an electrical short circuit and the remaining 10 were of unknown origin.Accordingly, this Preliminary Evaluation is closed.The ODI reports cited above can be reviewed at www-odi.
