The V3's issues stemmed from the design of the battery door. They re-designed the door 2 times and I thought all the bugs may have been worked out. Apparently, in May of this year, they did another redesign, however they are back ordered on the new door.
I had power spikes and dropouts on mine. I removed the batteries that they came with and replaced them with the 1 battery type and that has helped some. It constantly reads higher than my Tacx Neo 2T (however that could mean that the Tacx is wrong or both are wrong)... I would however tend to believe the Tacx over the V3 based on my experiences with the V3. For example, the Tacx registered 597 kj of work on yesterday's ride vs. 672 kj on the V3.
Hopefully Garmin is able to restock the new doors soon and I'll be able to get them replaced. They call it the "Vector 3 Small Parts Kit"
