- The Roll Over Side Curtain Airbags deployed and hit my head. Both sides deployed. - I was in 4Wheel Low Range. Driving with a group of trucks. The obstacle was a set of mud ruts. - All witnesses did not understand, nor have seen this happen. - Toyota sent me a report based on their review of the vehicle. They said the Roll Over sensors detected a roll-over event. They advised that it is a "predictive" system. That at some point in my driving through the mud ruts, the system thought I was rolling over... I was not anywhere near a roll-over. - I requested to know why the RSCAS button was removed. Toyota advised that it was governed by NHTSA to be removed from models produced after a certain year. - I do not want to have my vehicle repaired to "factory specifications" given the experience I had. Toyota could not negotiate that request on my behalf. This is my request to NHTSA.
