Late to the game, started having squealing several months back on my 2021 Model 3 (28k miles). Made appointment and Tesla sent message to try burnishing brakes first.
- Drive the vehicle at approximately 50 mph - 55 mph (80 km/h - 90 km/h) on a straight road.
- Apply moderate, consistent pressure to the brake pedal to slowly decelerate the vehicle, releasing at 10 mph (15 km/h).
- Repeat this procedure 6 times, waiting at least 30 seconds between applications.
So I did and it helped so I cancelled the appointment. It lasted about 4 days. I was busy and taking it to the Service Center was pretty inconvenient so I put it off. Finally last week I made an appointment to take the car in to a Tesla Service Center because it was embarrassing going through a drive thru and having extremely loud squealing brakes on a pretty newish low miles $43,000 car.
Tesla Technician came out and told me that it's just the natures of the car to get squealing brakes because they are used so infrequently. He said he they will check it out and probably do a burnishing. I told him I already did that an it only lasted 4 days and he said "yeah, it's a temporary remedy to the noise". He said they will take a look because it's under warranty but if I bring it back in for the same issue there will be a Brake Servicing Charge.
So it's normal to have squealing brakes apparently, because here I am, 5 days later with squealing brakes. I bought the car not only because of gas savings but because for minimal maintenance, but I've had more maintenance/repair issues in a 12 month period with this car than any other I've ever owned.
- Exterior Trim by Side Mirror was coming off, had mobile tech come repair
- 12V Battery was corroded. Found that when I did my first car wash about a week after getting the car delivered
- Ground strap was also corroded but the mobile tech didn't have one and they had to order a part to the service center, so had to wait and take it in.
- Rear Passenger Window FELL OUT onto the highway while driving to work one morning. Had it and regulator replaced. Window was intermittently not retracting when door was being opened. This caused stress fracture to glass which caused it to break from vibrations. replaced under warranty
- Burnishing & replaced O-ring on Trunk Power Strut.
