Airbags Vehicle recall #23V865000 · 2023 · 999,901 vehicles
What's wrong: A short circuit May develop in the occupant classification system (ocs) sensor, preventing the front passenger air bag from deploying.
Why it matters: An air bag that does not deploy during a crash increases the risk of injury.
The fix: Dealers will inspect and replace the sensor as necessary, free of charge. Interim letters notifying owners of the safety risk were mailed in February 2024. Some final remedy owner letters were mailed October 31, 2024. Letters will continue to be mailed in phases through January 2026.
