I was involved in an accident where a car pulled out in front of me causing my truck to T-bone them. I estimate I was traveling at 40 mph or so at the time of impact. My airbags did not deploy during this impact. I have never had an issue with the air bag system on this vehicle, but believe the dealership had performed a recall or flashed some software within the last 3 years pertaining to the airbag. I'm not sure if the computer detected the impact and decided not to deploy the airbags, or if they should have deployed and the system was faulty? I am a larger man and am glad the seatbelt restrained me, but am afraid someone with smaller stature, or unable to brace themselves before impact would not have faired as well. As it is, I am on day 4 of neck, back and whole body aches and whiplash which has caused a constant unbearable headache with light and sound sensitivity in the harsh summer that probably could have been lessened had the airbag stopped me?
