Clunking Noise from Front Suspension on New 2025 Polestar 3

Vehicle: 2025 Polestar 3 Long Range Dual Motor

Hello Polestar community,

I just picked up my brand new 2025 Polestar 3 Long Range Dual Motor a few weeks ago, and I've already noticed a concerning clunking noise coming from the front suspension. It happens when I go over bumps, speed bumps, or even just uneven pavement at low speeds.

Given how new the car is (only about 800 miles on it), I'm quite surprised and a bit worried. Has anyone else experienced anything like this with their Polestar 3 or other models? What could be causing this on such a new vehicle?

ClearTheCode admin answer:

A clunking noise from the front suspension on a new vehicle like your 2025 Polestar 3 is definitely something that warrants immediate attention. While less common on new cars, it can occur. Here's what might be happening:

  1. Potential Causes:

    • Loose or Faulty Sway Bar Links: These are a very common source of clunking noises over bumps. Even new parts can sometimes be defective or improperly torqued during assembly.
    • Worn or Damaged Bushings: Control arm bushings, strut mount bushings, or sway bar bushings could be faulty. While rare on a new car, manufacturing defects are possible.
    • Loose Strut Mounts: The top mounts of the struts can sometimes be loose or have a defect, leading to noise.
    • Loose Calipers or Brake Components: Less likely to cause a 'clunk' over bumps, but sometimes loose brake components can create similar sounds.
    • Damaged or Loose Components from Shipping: It's possible for something to have been jostled or loosened during transport to the dealership.

  2. Initial Steps (Limited for New Vehicle):

    • Visual Inspection: While you might not see much, a quick look under the front end for anything obviously loose or disconnected can sometimes reveal a simple issue.
    • Note Conditions: Pay attention to when exactly the noise occurs (e.g., only over large bumps, turning, braking) to help the technician diagnose it.

  3. When to See a Shop:

    • Immediately. Since your 2025 Polestar 3 is brand new and under warranty, this is a clear case for a dealership visit. Do not attempt extensive DIY diagnostics, as it could void parts of your warranty or complicate the repair.
    • Contact your Polestar Space or service center right away. Explain the issue thoroughly. They will likely need to perform a full suspension inspection, checking all bushings, links, struts, and mounting points. This type of issue on a new car points towards a manufacturing defect or an assembly error that should be covered under warranty.
