Honda should absolutely be higher too. And literally that study is worthless, there is no reliable common set standard for the results, which is probably why I can't even find the methodology used described in the article.

The below linked article based on a TÜV study, is based on legally mandatory safety checks performed by an independent third party:

In this way more rigorous and fair study, based on security issues detected at mandatory checks, VW turns out to be #1!
So clearly Toyota is NOT easily better than VW, Audi or Mercedes, which actually all beat Toyota in an actually useful fully transparent study.

It was claimed earlier that price was a factor in the study posted earlier.
In that regard, I can say that Tesla model 3 is hailed as the cheapest to maintain the first 4 years here in Denmark.
Many car reviewers noted that as a plus for Tesla. But the maintenance also suck balls, because after 4 years we have the first mandatory safety check, and 33% of Tesla model 3 fail that test, even with very serious issues like on steering and brakes. No other brand fails on steering after 4 years!!
So clearly basing it on cost is not worth shit. You may save a buck, and then die next time you need to make a double maneuver or brake hard.

Toyota are absolutely good cars, but they are not easily better than VW. They are mostly on par.
