Official summary
DP: The subject vehicles are equipped with Toyota Safety Sense (TSS) which consists of several driving assist features, including pre-collision braking, lane departure warning, and more. Due to inappropriate programming of the software within the forward recognition camera, there is a possibility that under certain conditions, TSS functions could become inoperative for approximately 4 seconds before rebooting and becoming operational again.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
