The defect
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2018-2020 Toyota Tundra vehicles equipped with LED headlight assemblies. Due to a wiring error, the front turn signals may not flash brightly enough. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
The risk
If the turn signals or hazard lamps do not flash brightly enough, other drivers may fail to see that the turn signal or hazard lamp functions have been activated, increasing the risk of a crash.
