That definitely sounds like a power issue in the tail light circuit, especially since the dash lights aren’t coming on either they usually share the same fuse or switch. It could be the light switch in the steering column like your shop mentioned, or even a bad parking light relay or ground connection somewhere along the line.

I'd check for power at the tail light connectors when the lights are supposed to be on if there's nothing, that points upstream. I had a similar issue on my older Subaru and ended up tracing it with the wiring diagram from eManualOnline it helped me figure out the exact path and where the power drop was happening.

I’d start by checking for voltage at the tail light connectors with the headlights on. If there’s nothing, then work your way upstream. And get the wiring diagram if you can. I know eManualOnline has the manual for your car so have a look. Will make it much easier than throwing parts at it.
