Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2026 Corolla vehicles. The front headlights may have missing headlight aim markings, which can result in improperly aimed headlights during service. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
Consequence: Incorrectly aimed headlights can reduce driver visibility or create a glare for oncoming traffic, increasing the risk of a crash.
Remedy: Dealers will replace both front headlight assemblies, free of charge. Owner notification letters were mailed April 20, 2026. Owners may contact Toyota's customer service at 1-800-331-4331. Toyota's number for this recall is 26TA05.
Size-standard part numbers — verify your connector type before buying. Rear blades are model-specific; check the package's vehicle list.
