Brake wear on other Model 3 years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2024, 2025, 2026.
What this problem usually is
Brake reports cover a wide spread of symptoms. Grinding or squealing is common, and so is a pulsing pedal or a shake through the car when stopping. Others describe pads and rotors worn out long before they expected, a brake warning light, or a pedal that goes soft or sinks toward the floor. The most serious ones say the car didn't stop in time.
What got replaced
Owners who name the part that was replaced mention the ABS module (5 reports).
Recalls and investigations
One recall on the brakes covers the 2021 model year. A recall on the same system isn't always the same failure, so read the defect text.
The brake caliper bolts may be loose, allowing the brake caliper to separate and contact the wheel rim.

When it happens
Too few of these reports state a mileage to give a range.
Is this a known problem?
The manufacturer has sent NHTSA 1 service bulletin or notice for the 2021 Tesla Model 3 that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.
On certain Model 3 vehicles, brake lines may be corroded beyond acceptable limits, which may result in loss of brake fluid. Loss of brake fluid will result in a customer facing alert if the fluid reaches the predetermined level to trigger an alert.

“While driving in cruise control, my Tesla 3 braked for no reason. No accident occurred because no one was behind me. It has happened about 10 times. It has not been confirmed by a dealer because I do not live near a dealer. It has not been inspected by the manufacturer, police or insurance representatives. No warning lights or messages appeared to warn me.”

“While using the autopilot feature on my Tesla, there have been several instances where the car will brake suddenly for no apparent reason. This has happened at high speeds and at slow speeds under various conditions. The braking is so severe that if a car was following behind they would have to react quickly to avoid an accident. Multiple instances over the last year.”

Should you keep driving it?
This page can't tell you that. 11 of 125 reports involved a crash and 5 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
