Did BMW tell your parents that the door not opening was normal and expected behavior?

This is just a lie. The Tesla rep said it sounded normal but that they would confirm so when the vehicle was brought in for the appointment. They never said a missing brake pad was normal and expected.

Except it isn't factually correct to say that a grinding sound is normal. Either the rep wasn't honest, made a call they should not have, or isn't trained correctly.

Tesla brake grinding to a certain extend is actually normal or my car is also has a defect. Since I use my brake so rarely. It happens all the time that they rust and I need to brake a bit to have the grinding disappear.

I could imagine the rap thought that was what the owner was hearing.

You are correct. I should have such such a grinding sound in a new car warranted a second look.

your car doesn’t sound like this. squealing is normal, this is clearly metal on metal.

rust buildup is also removed within the first few applications of the brakes.

if your car sounds like this get it checked before you have problems.

Or the crappy audio from the smartphone video didn’t portray the sound well and isn’t a good tool for diagnosing vehicle issues.

no, it’s quite clear from the audio that there’s metal on metal contact. even with metallic brake pads they don’t sound like this.
