NHTSA Complaint #11479700 — 2012 TOYOTA COROLLA

My Corolla flipped over upside down going 30 miles an hour. I collided with another vehicle that was stopped in the opposing lane of travel to turn left. We both barely were over center the line at impact that somehow caused my Corolla to roll upside down. Some how this did not deploy the safety airbags either. The airbags are not my complaint; but rather that I managed to flip upside down going 30 mph from a driver side collision. I’m writing in an attempt to understand why it wasn’t just an impact, but actually flipped the vehicle over. Also, why the safety airbags, which were recalled and repaired, did not engage upon impact. I just replaced the transmission 3 weeks prior to this bizarre accident, that may have totaled my vehicle. It’s still sitting in my garage because new investments had just been made to keep it in good shape for another year (transmission, tires, headlights, plate renewal, etc). I was planning to purchase a new Toyota suv the following spring or shortly after. Unfortunately this collision has derailed all future ambitions regarding my mode of transportation and forced me to purchase an extremely old Toyota Avalon in order for me to function in my daily life as a single parent. I am very fortunate to have escaped any serious injuries considering I was upside down, hanging from my seatbelt, and even more grateful that I had not gotten my 9 year old daughter yet. I was in route to pick her up around 4pm when it happened. I would love some insight or science as to why or how that could have happened. *side complaint- the grill of my Corolla has fallen off twice unnoticeably (and I purchased and replaced with a new one both times). Why are either the fasteners not stronger or why isn’t the bottom of the vehicle itself not stronger. It’s the flimsiest plastic which shouldn’t be used on something meant to transport the most precious cargo. I’ve noticed it is very common for many Corollas to be missing the grill piece since it’s become a “thing”.
