Official summary
Some vehicles with accessory installed wheel locks may have had the wrong kit installed using a 21 mm wheel lock key. As of May 01, 2018, Japan produced vehicles use 17 mm hex lug nuts instead of 21 mm on the same size thread. Follow the instructions below to replace the wheel lock kit with a 17 mm wheel lock key. NOTE: The Mazda3 produced in Mexico is not affected
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.
