No collision or impact occurred to trigger this and, correspondingly, no external damage to the vehicle was sustained. Post-airbag deployment, despite the unexpected bodily impact, sudden jolt, and visual obstruction caused by the airbags, I was able to maintain control of the vehicle and maneuver to a nearby parking lot. Upon visual inspection of the vehicle, I confirmed no evidence of collision. The following day, Honda ran full diagnostics on the vehicle. The dealership indicated tests would reveal certain codes triggered w/ airbag deployment (what caused them to deploy). Inspection results, however, revealed no codes found in the proprietary computer, nor other detectable evidence of any cause. I asked whether a defect was possible and was told this could neither be confirmed nor ruled out. Per the dealer's explanation, only the presence of improper codes could reveal this with absolute certainty. In essence, the only explanation I received was that no explanation could be found. Honda denied my request to put these details in writing. I was given only a vague summary of the damage and a list of costs required for repair, totaling to over $10,000 (invoice attached). Geico said damages caused by airbag deployment are not covered by any policy unless a collision is reported. If deployment occurs w/o collision but other valid causal factor(s) are detected by inspecti
