PE18-013 was opened on December 1, 2018, with 4 complaints to ODI alleging incidents of the lower control arm fracturing at a connection point to the vehicle chassis due to corrosion. ODI has received an additional 87 complaints since the PE was opened. During PE18-013, Nissan indicated model years 2013-2018 shared a common rear lower control arm design. Nissan provided complaint and warranty data regarding 48 incidents of the subject failure. The majority of the complaints are from vehicles registered in salt belt states. There have been no crashes, injuries, or fatalities confirmed as of this date. Nissan advised that it has conducted testing to assess safety risk. Nissan states that due to low incident rate, high detectability, and low risk of adverse vehicle dynamics, it does not believe the subject lower control arm failure poses an unreasonable risk to motor vehicle safety.This preliminary evaluation has been upgraded to Engineering Analysis (EA) 19-002. During the EA, ODI will continue to collect and analyze complaint and field data in its efforts to fully assess the scope and frequency of the alleged defect. More importantly, ODI will also seek additional information and data regarding the potential safety consequences of rear lower control arm failure, both from evidence collected from field failures and through more rigorous and comprehensive vehicle testing to be conducted by either Nissan and/or NHTSA.The ODI reports (VOQs) cited above can be viewed at NHTSA.gov under the following reference numbers: 11234334, 11234232, 11234189, 11233771, 11233234, 11232381, 11231589, 11230323, 11230184, 11229023, 11229003, 11228730, 11228651, 11228631, 11228625, 11223086, 11222602, 11222427, 11222303, 11221802, 11219943, 11217980, 11217542, 11217505, 11217290, 11210699, 11209647, 11208580, 11208274, 11207545, 11206310, 11205711, 11205461, 11203864, 11203005, 11195416, 11193545, 11193020, 11192269, 11192066, 11191270, 11191207, 11191185, 11191042, 11190360, 11190323, 11187334, 11187157, 11186747, 11186195, 11185664, 11185632, 11185589, 11183799, 11183295, 11183198, 11182705,11182528, 11182265, 11182137, 11182088, 11181373, 11181223, 11181155, 11181009, 11180126, 11176565, 11176261, 11176135, 11175821, 11172604, 11172200, 11172065, 11170019, 11169930, 11165194, 11163833, 11163489, 11162559, 11162195, 11161956, 11161497, 11161117, 11157323, 11157234, 11156772, 11141169, 11139516, 11129476, 11122829, 11114374.
