New European car registrations of Tesla vehicles totaled 8,837 in July, down 40% year-on-year, according to the European Automobile Manufacturers Association, or ACEA.
BYD recorded 13,503 new registrations in July, up 225% annually.
Elon Musk’s automaker faces a number of challenges in Europe, including intense ongoing competition and reputational damage to the brand.
Tesla's high failure rate is primarily due to rust on the brakes from people using regen. Rust will form on all brakes if left unused, it's just a matter of using them. There was also an issue with the front suspension that required a service bulletin at the time that was legit, but wasn't a saftey thing.
There's a few things that could lead to Tesla having higher rust rates over other EVs
Tesla might have stronger regen so people use the brakes less.
Tesla has a strong 1 pedal driving option which further reduces braking if enabled [0 brake pedal usage needed to come to complete stop, it will blend in brakes for the last few km/h]
For cars that use blended braking anywhere, they may initiate it sooner than later.
Either way on an EV, you need to use your brakes on occasion or rust will form. Using the brakes clears the rust.
Edit: Essentially, this is a case of the facts are true, but the facts don't always tell the whole truth. If you walk away from reading about this report thinking Tesla is the least reliable car, you've been mislead, unintentionally or not.
