Investigations Summary: On December 19, 2019, the office of defects investigation (odi) received a defect petition by email requesting a defect investigation of alleged sudden unintended acceleration in model year (my) 2012 through 2019 tesla model s, my 2016 through 2019 tesla model x, and my 2018 through 2019 tesla model 3 vehicles. In support of his request, the petitioner cited 127 consumer complaints to NHTSA involving 123 unique vehicles. The reports include 110 crashes and 52 injuries. A copy of the petition will be added to the public file for this defect petition and odi will evaluate the petitioner's allegations to determine if the petition should be granted or denied. If the petition is granted, odi will open a defect investigation; if the petition is denied, odi will publish a notice in the federal register. The following voq numbers were referenced in the defect petition:11291423, 11289172, 11289019, 11282993, 11280962, 11279755, 11278322, 11278152, 11269912, 11268280, 11267131, 11266551, 11265452, 11257753, 11241215, 11231846, 11229124, 11228597, 11220202, 11209483, 11209238, 11207877, 11206931, 11206155, 11202909, 11196764, 11189710, 11183545, 11183334, 11180431, 11174732, 11171052, 11165284, 11164094, 11162968, 11156706, 11155579, 11154380, 11154132, 11142282, 11139174, 11133222, 11132177, 11132094, 11128789, 11124067, 11121147, 11119991, 11118541, 11118315, 11113560, 11112860, 11111431, 11102931, 11102347, 11100721, 11100216, 11098517, 11097159, 11096621, 11093835, 11092830, 11092528, 11091970, 11089262, 11083755, 11083342, 11082114, 11081382, 11079500, 11078571, 11076619, 11075212, 11074547, 11073274, 11066047, 11065563, 11065308, 11064628, 11054973, 11048161, 11042211, 11021371, 11015893, 11003716, 11000077, 10995447, 10995382, 10982961, 10979378, 10970822, 10968322, 10958834, 10957394, 10953656, 10949955, 10939234, 10935272, 10915633, 10910108, 10910065, 10909588, 10908051, 10898260, 10893066, 10875699, 10874744, 10873117, 10864353, 10864163, 10862194, 10846206, 10845619, 10839579, 10810457, 10764853, 10758893, 10749575, 10723925, 10639849, 10562266, 10545488, 10545230the following voq’s were cited in the petition and are related to complaints referenced above as noted in parentheses:11282996 (11282993), 10758908 (10758893), 10725634 (10545230), 10639935 (10639849)
