What it saysPolestar Automotive USA on behalf of Polestar Performance AB, has decided to launch Delivery Action DP1033: PS3 MK C1 rattling noise on certain MY 2025 Polestar 3 vehicles. NHTSA’s full summary ↓

Polestar filed this with NHTSA as a service campaign dated Oct 19, 2024, received Nov 5, 2024, about the service brakes. It names 1 model year (2025). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

Owners of the 1 model year this bulletin names have filed 79 complaints with NHTSA since 2015.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions

Source: NHTSA, 49 CFR 579.5

Is Polestar DP1033 a recall?

No. A service campaign is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.

Is the DP1033 repair free?

A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.

Which vehicles does DP1033 cover?

The manufacturer filed it against 1 model year: 2025 Polestar 3. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
