This service bulletin provides a procedure to apply aluminum butyl tape around the lower side object modules and the fascia to aid in deflecting the radar away from the ground and stop triggering false alerts.
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.
