The vehicle experienced water intrusion into the interior cabin shortly after delivery in 2023. The water intrusion affected electrical components related to the airbag and Supplemental Restraint System (SRS). The vehicle remains in my possession and is available for inspection upon request. Moisture exposure to airbag and SRS components presents a serious safety risk because these federally regulated systems may fail to deploy, deploy improperly, or deploy unexpectedly in the event of a collision, increasing the risk of injury or death. The issue was reported multiple times to authorized Toyota dealerships while the vehicle was under factory warranty, and repair attempts were made; however, the water intrusion and related safety concerns were not resolved. The manufacturer and its authorized dealers were made aware of the defect through repeated service visits and customer complaints. Warning indicators related to the airbag/SRS system appeared after the water intrusion occurred, and the defect first manifested within weeks of vehicle delivery in 2023.

While turning right at approximately 5–10 mph, the vehicle was struck on the front passenger side. The impact caused moderate intrusion of the passenger door, severe damage to the front-right corner of the vehicle, and damage to the dashboard. Despite the structural damage and intrusion into the occupant compartment, none of the airbags deployed, including driver frontal, passenger frontal, side torso, or curtain airbags. Both occupants were wearing seatbelts, which activated normally. The driver sustained a right-side rib fracture caused by seatbelt force, required ambulance transport to the emergency room, and continues to experience ongoing symptoms. A child passenger seated in the front passenger seat struck her head against the window, resulting in a brain concussion with symptoms including headache and dizziness, requiring emergency medical evaluation. No airbag warning lights were present before or after the crash. The vehicle is preserved in post-crash condition and is available for inspection. This appears to be an airbag system failure / crashworthiness defect that resulted in enhanced injuries due to airbag non-deployment.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2023 Toyota Sienna verdict →
