That's what I've done with everything I can when it happens. Loss of audio, frozen 8.4", brake squeal, etc., are all in pictures or video.
I give a detailed printout (including pictures) to the service advisor/writer when I drop it off so they have the proof and eliminates most of the "tech cannot reproduce" issue. I'll show them any videos too. I've also found a dealership that has been helpful rather than dismissive. They are 20 miles away but I will make that drive every time for service and parts because the one down the street from me s-u-c-k-s (service and sales). I also go to the same service advisor as he knows my truck and my expectations. With few exceptions I have been happy with the outcome (and I've still got 14K more miles to convince them of the rest).
I broke my cardinal rule: NEVER buy a vehicle the first year of production (new line, new generation, or redesign). Unfortunately I was collected in an accident and my truck was totaled, leaving me in the market for a new vehicle earlier this year. I knew I would have more issues than normal since it's the first year of the 5th gen truck but nothing else I sat in or drove came close to how much I liked the "all-new" 2019 RAM 1500. So I bit the bullet, broke "the rule", and bought one.
Next week will be my 4th visit to the dealership for work (in 10 months), including round 2 for squeaky brakes (I would attempt it myself but as long as the dealership is doing it for free I'll let them...plus it's logged in the VIN history). It's more that I had hoped so far but less than I expected. Luckily it's nothing catastrophic and the truck hasn't left me stranded anywhere so I consider it a win so far.
