Yes, and the city taxes its residents to pay for the police—the same residents who bought the cars requiring more police involvement.

It's a self-correcting problem, no lawsuit required.

The city could even have a special tax on "cars without immobilizers" that Kia owners paid, to cover their costs. Again: no lawsuit required.

The city is expected to police all crime regardless. The car manufacturer might (or might not) have some duty to the customer in this area, but certainly not the city for contributing to a crime increase.

You might as well say that a company that produces an exceptionally desirable product, one that perhaps entices thieves, would be responsible for a crime increase.
