You can see this skew quite easily on these reports by looking for VW AG cars that are generally identical, and comparing their rankings, like Audi A1, VW Polo, Seat Ibiza and Skoda Fabia.
(note that this isn’t really to defend Teslas, which are clearly behind on this metric in Germany for some reason. Just; the reason could be “their service is overpriced and nobody wants to take the car in” rather than “the car is junk.”)
Are the Germans biasing toward their companies? Or am I underrating VW’s quality?
Second, as described in other comments, this is just an analysis of safety inspection data. So you've got to consider the ease with which people can "just take it to the dealer", how much they trust the dealer and the kind of people who buy what (Altima factor).
Our Benz sprinter needed an engine at 11k miles.
I wonder what they count as defects.
Funny enough, my 2007 BMW had so many issues and cost so much to maintain i used to call it a “wallet burning machine”
He’s got an early 90s 525i BMW and I’ve got a 2000 SR5 Toyota 4Runner.
The engineering of my Toyota is so much simpler and easier to work on than his BMW. But his BMW has given us a lot more practice, if you know what I mean ^_^
They find faults long before your car breaks down
Just because you haven't personally encountered a serious defect doesn't mean there's no problem with it at all.
* Tesla Model Y ranked most unreliable among nearly new cars, with 17.3% serious defect rate.
* TÜV report found rising major defects, particularly in electric vehicles like Tesla’s Model 3 and Y.
* European brands, especially Mercedes and Volkswagen, dominated reliability rankings across all age groups.
