The failure pattern owners describe
Owners of 2021 Toyota Highlanders report two documented crash incidents where airbags failed to deploy. In one July 2025 freeway accident, the driver received a dashboard "SRS Airbag System Malfunction" alert and the airbags did not deploy; in another incident, a pregnant driver was rear-ended and sustained neck injuries, with airbags again failing to deploy. Toyota issued recall 23TA15 (NHTSA 23V865000) on December 20, 2023, acknowledging the passenger airbag may not deploy in a crash. As of mid-2025—over 18 months later—no repair parts exist in dealer inventory.
Multiple owners report illuminated airbag warning lights; one dealer quote indicated a failed passenger seat sensor would require approximately $2,000 to replace, though the shop stated the entire system becomes non-functional because of a single sensor failure.
Toyota initially promised a remedy by Q3 2024; that estimate has missed repeatedly. Dealers and Toyota Brand Engagement Center confirm parts remain unavailable with no firm ETA. Some owners report Toyota offered 25-day loaner periods but refused to guarantee fitting family-sized vehicles. Owners describe being stuck driving vehicles with known safety defects or facing two-year repair waits and unable to sell due to open recalls.
