In March of 2011, I was operating my 2005 Nissan Frontier (4-door crew cab, 4x4, nismo package) on a dirt road with one front seat occupant. Vehicle came in contact with washboard/rutted section of road, when the side curtain airbags deployed for an unknown reason, resulting in minor injuries and damage to interior of vehicle and immobilization due to lack of safety equipment (seat belts became inoperable). Nissan consumer affairs investigated vehicle, and would not pay for repairs, as they "did not find any malfunctions. " I am now stuck with a damaged vehicle for a problem I did not cause.
Side impact/roll-over air bags deployed unexpectedly in my truck while off-road on a bumpy but level surface.
