Official summary
Some vehicles may have a water leak and/or a technician may find water inside the cabin or within a component. The source of the leak may be from between the doors at the B-pillar. To correct this concern, there was a mass production change (MPC) on January 14, 2021 to reduce the gap (as seen in the image below).
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.
