3PE12009 · Skid Plate Debris Fires
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.

ON JULY 3, 2007, DAIMLERCHRYSLER CORPORATION (DCC) SUBMITTED A DEFECT INFORMATION REPORT TO NHTSA DESCRIBING A DEFECT THAT COULD RESULT IN ENGINE STALL WHILE DRIVING IN APPROXIMATELY 80,894 MODEL YEAR (MY) 2007 JEEP WRANGLER AND DODGE NITRO VEHICLES MANUFACTURED BETWEEN JANUARY 30, 2006 AND JANUARY 22, 2007 (NHTSA RECALL 07V-291, DCC RECALL G25).ACCORDING TO DCC, THE TOTALLY INTEGRATED POWER MODULE (TIPM) IN THESE VEHICLES WAS PROGRAMMED WITH SOFTWARE THAT MAY ALLOW THE ENGINE TO STALL UNDER CERTAIN CONDITIONS.DCC WILL REPROGRAM THE TIPM IN THE RECALLED VEHICLES WITH REVISED SOFTWARE. ODI OPENED PE07-027 ON MAY 29, 2007, BASED ON 53 COMPLAINTS ALLEGING ENGINE STALL AND/OR LOSS OF ELECTRICAL POWER IN MY 2007 JEEP WRANGLER VEHICLES.ODI WAS ALSO MONITORING SIMILAR COMPLAINTS IN MY 2007 DODGE NITRO VEHICLES.DCC'S ANALYSIS OF COMPLAINTS TO DCC AND NHTSA FOUND THAT MANY DESCRIBED EVENTS WITH A MOMENTARY LOSS OF ELECTRICAL POWER INSIDE THE VEHICLE AND A CORRESPONDING LOSS OF ENGINE POWER.MANY OF THE REPORTS ALSO INDICATED THAT THE INSTRUMENT CLUSTER TELLTALE LAMPS MOMENTARILY ILLUMINATED DURING THE EVENT. DCC'S ENGINEERING ANALYSIS DETERMINED THAT THE TIPM COULD INITIATE AN INTERNAL RESET CYCLE LASTING APPROXIMATELY 75 MS IN RESPONSE TO ERROR MESSAGES ON THE COMMUNICATION BUS.THE KEY ON SIGNAL FROM THE TIPM TO THE POWERTRAIN CONTROL MODULE (PCM) IS LOST DURING A TIPM RESET.IF THE PCM LOSES THE KEY ON SIGNAL FOR LONGER THAN 40 MS, IT INTERPRETS IT AS THE VEHICLE IGNITION BEING TURNED OFF AND BEGINS A POWER DOWN ROUTINE.AFTER THE TIPM RESET, THE KEY ON SIGNAL IS RESTORED AND THE PCM POWERS BACK UP.IF THE ROTATING COMPONENTS OF THE ENGINE CONTAIN SUFFICIENT INERTIA, THE VEHICLE MAY RESTART WITH NO INPUT FROM THE OPERATOR AS REPORTED IN SOME OF THE COMPLAINTS.IF THE ENGINE DOES NOT RESTART IN THIS MANNER, IT CAN BE RESTARTED BY THE OPERATOR.A REVISION TO THE TIPM SOFTWARE ON JANUARY 22, 2007 CHANGED THE TIPM RESET TIME TO 17 MS, REMOVING THE POTENTIAL FOR PCM POWER DOWN AND ENGINE STALL. ODI HAS RECEIVED 178 COMPLAINTS POTENTIALLY RELATED TO THE ALLEGED DEFECT IN MY 2007 JEEP WRANGLER VEHICLES AND 52 COMPLAINTS INVOLVING MY 2007 DODGE NITRO VEHICLES.TWO OF THE NITRO COMPLAINTS ALLEGE THAT A CRASH RESULTED FROM AN ENGINE STALL INCIDENT, ONE OF WHICH CAUSED MINOR INJURIES TO A PASSENGER.AS OF JUNE 1, 2007, DCC IDENTIFIED 151 WRANGLER COMPLAINTS AND 128 NITRO COMPLAINTS. THIS INVESTIGATION HAS BEEN CLOSED WITH DCC'S RECALL.

DCC'S ENGINEERING ANALYSIS DETERMINED THAT THE TIPM COULD INITIATE AN INTERNAL RESET CYCLE LASTING APPROXIMATELY 75 MS IN RESPONSE TO ERROR MESSAGES ON THE COMMUNICATION BUS.THE KEY ON SIGNAL FROM THE TIPM TO THE POWERTRAIN CONTROL MODULE (PCM) IS LOST DURING A TIPM RESET.IF THE PCM LOSES THE KEY ON SIGNAL FOR LONGER THAN 40 MS, IT INTERPRETS IT AS THE VEHICLE IGNITION BEING TURNED OFF AND BEGINS A POWER DOWN ROUTINE.AFTER THE TIPM RESET, THE KEY ON SIGNAL IS RESTORED AND THE PCM POWERS BACK UP.IF THE ROTATING COMPONENTS OF THE ENGINE CONTAIN SUFFICIENT INERTIA, THE VEHICLE MAY RESTART WITH NO INPUT FROM THE OPERATOR AS REPORTED IN SOME OF THE COMPLAINTS.IF THE ENGINE DOES NOT RESTART IN THIS MANNER, IT CAN BE RESTARTED BY THE OPERATOR.A REVISION TO THE TIPM SOFTWARE ON JANUARY 22, 2007 CHANGED THE TIPM RESET TIME TO 17 MS, REMOVING THE POTENTIAL FOR PCM POWER DOWN AND ENGINE STALL. ODI HAS RECEIVED 178 COMPLAINTS POTENTIALLY RELATED TO THE ALLEGED DEFECT IN MY 2007 JEEP WRANGLER VEHICLES AND 52 COMPLAINTS INVOLVING MY 2007 DODGE NITRO VEHICLES.TWO OF THE NITRO COMPLAINTS ALLEGE THAT A CRASH RESULTED FROM AN ENGINE STALL INCIDENT, ONE OF WHICH CAUSED MINOR INJURIES TO A PASSENGER.AS OF JUNE 1, 2007, DCC IDENTIFIED 151 WRANGLER COMPLAINTS AND 128 NITRO COMPLAINTS.
