Crash Related Fuel Tank FiresClosedLed to recall 13V252000
ODI has completed an extensive analysis of rear crash fuel tank system integrity data for the subject Jeep Cherokee, Grand Cherokee and Liberty vehicles (SVs).As of June 2013, ODI knew of 56 post-collision fatal fires, 28 non-fatal fires, and 6 fuel leak incidents (totaling 90 incidents, 75 fatalities and 58 injuries) involving the SVs.Based on this analysis, ODI issued a Recall Request Letter (RRL) on June 3, 2013 requesting that Chrysler recall the Grand Cherokee and Liberty vehicles due to the rate of fatal, non-fatal fire, and fuel leak incidents when compared to peer vehicles (compact and medium SUVs) built during the same time period.In the RRL, ODI described how the location of the aft-mounted fuel tank made the SVs vulnerable to rear impact crash fuel tank failures.During the analysis, besides the high speed/high severity crashes present in both the SV and peer vehicles, ODI…

NHTSA has conducted extensive analysis of the data regarding fuel tank integrity for the model year (MY) 1993-2004 Jeep Grand Cherokee (JGC). As a result of that work, the agency has decided to upgrade its safety defect investigation to an Engineering Analysis and to expand the scope of vehicles included in the investigation. NHTSA's assessment of the data collected during this investigation indicates that rear-impact-related tank failures and vehicle fires are more prevalent in the JGC than in the non-Jeep peer vehicles. In addition, the agency's analysis of its FARS data for the peer vehicles and three Jeep models shows a higher incidence of rear-impact, fatal fire crashes for the Jeep products.PE10-031 had focused on the fuel tank system integrity of the JGC vehicles during rear-end collisions and impacts.The fuel tank is located at the rear of the vehicle, between the bumper and…

In a letter dated October 2, 2009, the Center for Auto Safety (CAS) petitioned NHTSA to open a defect investigation and recall model year 1993-2004 Jeep Grand Cherokees.CAS alleged that the subject vehicles have defective fuel tank storage systems that present a fire hazard in crashes. CAS alleged that the plastic fuel tank's placement behind the rear axle and below the rear bumper, and the lack of adequate shielding, make it more vulnerable to rupture or leakage from a rear-impact by another vehicle (including damage from other components located on the Grand Cherokee), or in the case of rollover crashes, from other external objects.CAS also alleged that the fuel filler neck tears off in crashes.In its petition, CAS cites data from NHTSA's Fatality Analysis Reporting System (FARS) showing 172 fatal fire crashes with 254 fatalities involving the subject vehicles from calendar years 1992…

ODI OPENED EA02-029 TO DETERMINE WHETHER A SAFETY-RELATED DEFECT TREND EXISTED IN THE MY 1997 JEEP GRAND CHEROKEE HOOD LATCH ASSEMBLIES.DURING EA02-029, THERE WAS NO SPECIFIC FAILURE MECHANISM IDENTIFIED THAT COULD DIFFERENTIATE THE MY 1997 VEHICLES FROM OTHER VEHICLES CONTAINING THIS SAME HOOD LATCH ASSEMBLY OR COULD ACCOUNT FOR THEIR HIGHER COMPLAINT RATE.AS A RESULT, ODI EXPANDED THE SCOPE OF THIS INVESTIGATION TO INCLUDE ALL GRAND CHEROKEE VEHICLES EQUIPPED WITH THE SUBJECT HOOD LATCH ASSEMBLIES.IN PERFORMING EA02-029, IT WAS DETERMINED THAT SOME OF THE SECONDARY HOOD LATCHES IN THE SUBJECT VEHICLES MAY EXHIBIT INCREASED OPERATING FRICTIONAL RESISTANCE; HOWEVER, SINCE NONE OF THE PRIMARY HOOD LATCHES SHOWED ANY EVIDENCE OF MECHANICAL OR OPERATIONAL DEFICIENCY AND THE COMPLAINT RATE OF HOOD FLY-UPS MEASURED OVER AN EXTENDED EXPOSURE TIME WAS LOW, A SAFETY-RELATED DEFECT TREND HAS NOT…

VEHICLES USE THE SAME MANUAL DETENT LEVER THAT AS THE VEHICLES IN THE RECALL POPULATION, ODI BELIEVES THAT THE WJ REDESIGNED SHIFTER, WHICH IMPROVES FLOOR SHIFTER FUNCTIONALITY AND ERGONOMICS, HELPS TO PROVIDE FEEDBACK TO THE DRIVER TO INDICATE WHETHER ?PARK? HAS OR HAS NOT BEEN ACHIEVED.ALTHOUGH THE INVESTIGATOR WAS ABLE TO INDUCE A ?FALSE PARK? IN THE WJ PLATFORM FOR 6 CYL. VEHICLES, THE LEVEL OF DIFFICULTY WAS GREATER THAN THAT REQUIRED FOR ALL ZJ MODELS, AND THE COMPLAINT RATE WAS SIGNIFICANTLY LOWER THAN THE RECALLED ZJ POPULATION.FURTHER, THE ODI INVESTIGATOR WAS ALSO ABLE TO CREATE A ?FALSE PARK?
