  Summary

  Toyota is conducting a noncompliance equipment recall involving certain Rear Combination Lamp service parts for Toyota bZ4X sold from December 2023 to November 2025 in the U.S. Approximately 80 service parts are involved in this recall. The subject rear combination lamp service parts were sold in the U.S. even though they were intended for an overseas market. These parts do not meet a federal safety standard because they have a side marker reflector instead of a side marker lamp. In the absence of light reflecting off the reflector, this can reduce the ability of other road users to identify the rear of the vehicle from the side, potentially increasing the risk of a crash.
