2012 Accord vibration from 2,000 to 3,000 RPM

Hi guys, I joined this forum in case someone can help me while my car is still in warranty.

I recently bought a 2012 Honda Accord Euro Luxury Manual MY12 - 65,000 km's. There is a strange 'gurgling' vibration between 2,000 to 3,000 RPM in any gear or idle, most noticeable in 1st and 2nd gear (this is a video that shows it in idle but you can get the idea https://www.youtube.com/watch?v=rxFERDAduM0). You can feel the vibration on the steering wheel, it kind of sounds like a resonance. You can feel it slightly when cruising at 60 in 4th gear (around 2000) RPM. Is this normal? Is there anything I can do to make it smooth like the rest of the rev range? There is no impact on performance, loving the car otherwise but wanted to get some advice while it's still in warranty.

It's my first Honda so I don't know what to expect, but I thought Hondas were usually meant to sound quite smooth? Like I said the rest of the rev range (up to 2k and about 3k) sounds very smooth and steady. Anyway I wanted to ask in case it's either something common and expected, or in case someone can point me in the right direction to fix it if there's something wrong.

I took it to the Honda dealer where I bought the car and they said it's normal for the model, but only because it sounds similar to another Accord around the same year, they didn't go any further to diagnose. My regular mechanic also acknowledged the noise but he couldn't quite put his finger on it, without taking the engine apart to diagnose it.

I found a couple of threads on the forum that may have hints, but I couldn't find a clear answer just by reading through them, any thoughts or help would be greatly appreciated:
