Oh please, every car company has occasional problems where a few cars aren't made properly, which is what you gave examples of with Tesla. It's rare for it to be a design problem and for the problem to be so bad that they have to issue a recall on many thousands of cars as BMW had to do with e36s and e46s. I think it's safe to say that BMW has had far more structural unibody problems than Tesla.Yeah, that subframe cracking is horrible. Usually seen on cars of 10+ years old, rather 15.
Meanwhile Tesla doesn't have issues with delivering cracked new cars
But weldings don't hold for long either
P.S. I initially received the recall notice on my 330i when it was 7 years old.
