Official summary

Service Bulletin - The ACC system error message comes on while driving when outside temperatures are low/near freezing due to snow and ice getting stuck to the front of the millimeter wave radar. This can cause DTC P2583-76 (Temporary stop of Integrated Driver Support System [Misalignment Millimeter Wave Radar]) to be stored.

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.
