On I was involved in a collision with another vehicle on , while driving my 2023 Toyota bZ4X.

Common questions
Source: NHTSA, 49 CFR 579.5Is Toyota 23TC01 TI - Publ a recall?

Is the 23TC01 TI - Publ repair free?

Which vehicles does 23TC01 TI - Publ cover?
The manufacturer filed it against 3 model years: 2023 Toyota Corolla, 2023 Toyota Corolla Cross, 2023 Toyota bZ4X. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
