Vehicle: 2018 Tesla Model 3 Long Range

Hey everyone,

I've been experiencing some really annoying squeaky brakes on my 2018 Tesla Model 3 Long Range. It's most noticeable at low speeds, like when I'm pulling into a parking spot or coming to a stop at a light. It's been happening for a few weeks now and doesn't seem to be getting better.

I live in a dry climate, and I drive pretty conservatively. I thought maybe it was just dust or something, but it's quite loud and embarrassing. Is this a common issue with Model 3s? Could it be a sign of something more serious?

Any advice or shared experiences would be greatly appreciated!

ClearTheCode admin answer:

Squeaky brakes on a Tesla Model 3, especially at low speeds, are a fairly common complaint and can stem from several causes. It's often not an immediate safety concern, but it's worth investigating.

Common Causes:

  1. Brake Dust Accumulation: Teslas rely heavily on regenerative braking, which means the friction brakes aren't used as frequently or as hard as in traditional ICE vehicles. This can lead to a buildup of brake dust, which hardens on the pads and rotors, causing noise.
  2. Rotor Glazing: Similar to dust, infrequent hard braking can cause the rotor surface to become glazed, which also contributes to squealing.
  3. Corrosion: In some climates, especially those with high humidity or road salt, the brake components can develop surface rust, which can cause noise until it's worn off.
  4. Worn Pads or Rotors: While less likely if the car is relatively new and driven conservatively, excessively worn pads or rotors can also cause noise. The wear indicators might not be triggering yet.
  5. Caliper Issues: Rarely, a caliper might be sticking or not retracting properly, leading to uneven pad wear and noise.

What You Can Do:

  1. Perform a "Brake Scrub" (Hard Braking): Find a safe, open road and perform several firm, controlled stops from about 60 mph down to 10 mph. Do this 3-5 times, allowing some time for the brakes to cool between stops. This helps to clean off dust and re-bed the pads.
  2. Visual Inspection: If comfortable, visually inspect your brake pads and rotors for excessive wear, rust, or obvious damage. Look for any uneven wear patterns.
  3. Check for Recalls/Service Bulletins: Sometimes, specific model years might have known issues or service bulletins related to brakes. Check with Tesla service or online forums.

When to See a Shop:

  • If the squeaking persists or worsens after performing a brake scrub.
  • If you notice any grinding sounds, which indicate metal-on-metal contact and severe wear.
  • If the brake pedal feels spongy, soft, or requires more effort than usual.
  • If you observe any warning lights on your dashboard related to the brake system (e.g., "Brake System Warning" or ABS light).
  • If you see excessive rust or damage to the rotors or calipers during a visual inspection.

A service center can perform a full brake inspection, clean the calipers, and potentially resurface or replace pads/rotors if necessary. They can also check for any diagnostic trouble codes (DTCs) related to the braking system, though squealing alone typically doesn't trigger codes unless there's a sensor issue.
