Lexus LX · 2022–2024
Multiple 2022-2024 Lexus LX owners reported persistent SRS/airbag warning messages and dealer diagnoses related to the front passenger occupant classification system and related airbag components. This generation shares Toyota/Lexus safety-system campaigns affecting front seat occupant sensing and airbag readiness, and owners describe warning lights, repeated dealer visits, and concerns about whether the passenger airbag will deploy correctly. Because the issue directly affects restraint-system operation, it is considered high severity even when the repair itself is covered by recall or warranty.
Common Symptoms
- SRS warning light illuminated
- Airbag system malfunction message
- Passenger airbag OFF/ON status behaving abnormally
- Warning appears after moving front passenger seat
- Repeated dealer visits for airbag-related faults
How to Fix
Scan the SRS system with a Toyota/Lexus-capable diagnostic tool and inspect the passenger seat weight/occupant classification components, seat harnesses, and any applicable recall campaign status by VIN. Dealers typically perform recall remedies, recalibration, or replacement of affected seat sensor/airbag-related parts, then clear codes and verify the occupant detection status with a seat calibration procedure. If the warning returns, wiring under the seat and connector tension should be checked carefully.
