I think with the German TÜV numbers it is not quite as clear cut.
My understanding is that telsa unlike other manufacturers doesn’t require regular inspections to keep warranties. So it might just be that other brands have just as many faults, but they get caught and fixed during those regular inspections, rather than at the official TÜV. Which wouldn’t show up in that dataset.
I haven’t seen any studies accounting for that discrepancy, but I’d be curious to see whether the higher failure rate persists after accounting for that.
You are right, no mandatory inspections required from Tesla. Saves a lot of money.
Most TÜV faults were the brakes and the suspension.
The friction brakes are almost never used so they rot and rust. Tesla could easily fix that with a software update that uses them every now and then while breaking. Not sure why they haven’t already, because the problem has existed forever. You can easily avoid the problem by using the friction breaks every few months. Afair the most reliable way is to break when the car is in „N“.
Teslas suspensions have never been really good and they had issues with especially poor quality parts a few years ago. Of course a regular inspection would have found them early, but since those don’t exist, TÜV was the first to fault cars left and right. Newer and replacement parts are supposedly of higher quality. If that is true the TÜV statistics should improve for Tesla over the next years. We shall see.
