No, they dont.

My EX Wife's car (96 Eclipse RS) was at Sarasota Mitsubishi getting a new tranny installed and it was broken into. Stole same shit, amps, stereo, CDs... all kinds of shit. Smashed window, broke door handle. It was on their lot when it happened. They were not responsible. I fought it forever. Worse than that, the didn't even tell me it happened until I was there to pick up the car! Assholes. I hate thieves and car dealers.
