Wait... how fast were you driving, loukywells? If you were the sitting duck, that's probably why it didn't deploy.

I think it's when your relative speed is 15mph unless you dive nose underneath a semi or truck which allow the bumper to have late contact with an object.

Then, with this logic, the airbags should have gone off.. in this situation (35mph).

It should be. This is a head on collision, so the actual momentum and deceleration he experienced were greater than if he's hitting a still object at 35mph.

I bet the person who reply the email, doesn't even study the case or pass it the right person. Try contact someone else, if necessary email the VP or President. So, they'll take it seriously. I'm interested in what NHTSA has to say.

But if deceleration is GREATER isn't that more the reason the airbags should go off?

With the amount of damage the OP reported (and showed in photos) and his injuries he explained and had to take medication for, I'm going to say that the airbags SHOULD have gone off.

I agree LeeAnn. Most bumpers now designed to sustain 5-10mph impact depending on manufacturers♦. So, in that sense you won't see any damage to your bumper if you hit an object with well distributed area of impact. at 15mph the airbag should went off. So, you can see from the damage it's waaaaayy faster than those numbers. I don't understand why it didn't deploy. Maybe the sensor isn't working?

Do the onboard computers store information such as speed, acceleration, ..etc? The scangauge is hooked up to the OBDII port which shows the onboard computer is constantly monitoring different measures such as RPM, speed, mpg, ..etc. If available, maybe this info could be used to determine the stats from the crash?

Yup exactly my point and as pointed out, it's about that threshold acceleration/deceleration value. Unless Toyota logs that info in a crash (which I believe they do), NTSA should be able to get a clearer picture of why the airbag didn't deploy.

I was traveling through an intersection at 35mph and I never hit my brakes.

I talked to the appraiser today (my insurance company) and she stated that sometimes they deploy and sometimes they don’t, which unacceptable to me. The estimates for repairs are $9,100.

To make things worst, the other party has lied to the police twice and now has lied to his own insurance company stating that I'm at fault. Is there such a thing called integrity these days? On the police report it states that he failed to yield and I had a witness. The bottom line is my word against his and it will turn out to be a 50% liability on me, which is so wrong. We shall see what happens.

OK, I'm done venting :-)

Another way to get those numbers is when they get the picture of the other car involved in collision and study the damage to get some idea how fast the two were.
