For the second time in a month today the M3LR we use daily suddenly had a very load metallic grinding or scraping noise. If we had had one I would have sworn the exhaust had fallen off and was scraping on the ground. It happened about a mile from home, not when we first set off. We pulled over immediately. The first time after checking all round and under the car we set off tentatively and the noise had gone. The second time I was not there and my wife was driving. I headed out to her and we called Tesla.
This is totally different to the lighter noise you get from a bit of rust build up for example Discs grinding noise . It was quite alarming and for added shock factor some how coincided the second time with a message from the emergency SOS system that apparently was totally unrelated. Nothing like a big red warning and loud noise to make you sure your car is bust.
If it happens to any of you it is a known issue. I guess in theory it could happen to other cars but I have never heard of it before. "It is likely that a rock or debris has become wedged between the brake rotor and brake shield". There is a published procedure on the Tesla site
Do It Yourself - Model 3
but Tesla actually email you slightly different suggestions that worked for us
- Steer completely to the right, then move the car back and forward
- Steer completely to the left, then move the car back and forward
- Press brake pedal several times
- Set D and move the car a few meters
- Set R and move the car a few meters
- Set drive and brake abruptly, repeat 3 times
