“What component or system failed or malfunctioned, and is it available for inspection upon request? Response: Frame, Suspension, Airbags / Yes it is available for inspection. How was your safety or the safety of others put at risk? Response: Safety was put at risk due to frame & suspension failure due to severe rust. Also due to failure of deployment of AirBags. Rusted Frame Failure subsequently caused safety of Injured Party and other motorists to be at risk due to the Injured Party’s 4Runner to dart across oncoming lane of traffic with no warning other than a swaying motion felt immediately before losing control. Once the Injured Party lost control of the 4Runner it crossed into oncoming traffic, progressing into the drainage ditch on the oncoming traffic side of highway. Once the 4Runner impacted the drainage ditch at a 90° angle, the 4Runners momentum dispersed by causing the 4Runner to overturn 3 times landing on its wheels in the adjoining field. Has the problem been reproduced or confirmed by a dealer or independent service center? Repaonse: Independent Service Center has confirmed the problem with the Rusted Frame, Rusted Suspension, and Air Bag failure.…”
