Car wash liabilities?

this occurred in PA…

today I took my car which unfortunately is controlled by a touch screen to a car wash I’ve been to before and after detailing the interior

My screen became unresponsive which means my car was no longer driveable… I pointed it out to the person and they immediately denied touching it …

I got it to work luckily but it made me wonder what would’ve happened if I hadn’t… this seems like a huge risk factor for car washes with a lot of newer cars having touch screens in them… thanks
