The 10% is not as bad as it sounds, because the author fails to mention that these statistics are heavily in favour of expensive cars with a good dealership network. And Tesla has no dealerships at all, as far as I know.
When you own something like a BMW, you typically don't drive the car to the inspection yourself. Especially not if it's a leased or company car. Instead, you bring your car to the dealership (or they will pick it up), they inspect the car, fix any issues they encounter and only then bring in an official inspector for the actual inspection. This way, the inspector will hardly find any issues. Also, dealerships typically don't chose TÜV, but one of their competitors that do the inspection at the dealership.
TÜV is where people go who want to save money by skipping the dealership. Most people who do this drive cheaper cars. That's why cheap cars are always having much worse numbers in these statistics. They are alternative statistics, like ADAC's (Germany's equivalent to AAA), but they all have the same problem. There are no good statistics for German cars. They all favour expensive German brands because those who the statistics will never see a broken car. The dealerships will always take care of that. I'd rather trust US-based Consumer Reports than TÜV or ADAC statistics.
