Toyota — Weak safety mechanisms in Toyota Innova

Address:

560076

I WAS an owner of a Toyota Innova and 2 weeks ago, my Innova was stolen. It was parked right infront of my house and when I complain to the police, I get to know that stealing Innova is common. When I google about it, I get to see many complaints related to Innova's being stolen across the country. I am sure Toyota also knows about it. Why has not Toyota warned its customers about the lack of safety measures in Innova ? Why have Toyota not implemented any safety mechanisms in Innova?
