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 observed a significant number of low and moderate speed rear impact crash related fires and leaks, particularly in the Liberty.The data also demonstrated that SVs originally equipped with towing hitch receivers (trailer hitches) appeared to be under-represented in rear-impact related fuel tank failures.In the RRL, ODI requested that Chrysler provide its response by June 18, 2013, otherwise NHTSA might proceed to an Initial Decision that the SVs contain a safety-related defect.Chrysler responded to the RRL on June 4, 2013 and vigorously disputed the tentative findings of the RRL.Among other things, Chrysler argued that the SVs had an overall safety record superior to their peers, met or exceeded all applicable federal motor vehicle safety standards (FMVSS) and only experienced fires in severe high energy rear impacts.Nonetheless, while continuing to maintain that the SVs did not contain a safety-related defect, Chrysler proposed a recall (13V-252) of approximately 2.5M (1.6M currently registered) model year (MY) 1993 - 1998 Grand Cherokee (ZJ) and MY 2002-2007 Liberty (KJ) vehicles on Jun
