Polestar bulletin 37798.1.0
What it saysThis is a TJ - Text only - no attachment - Do not perform fault tracing or replace any parts before reading this journal. NHTSA’s full summary ↓
Polestar filed this with NHTSA as a service bulletin dated May 2, 2026, received Jul 14, 2026, about the power train. It names 5 model years (2021–2025). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationThis is a TJ - Text only - no attachment - Do not perform fault tracing or replace any parts before reading this journal. An acceleration constraint from a standstill when the driver's seatbelt is unbuckled has been implemented and should be regarded as expected behavior. The models listed in this journal are the first to receive this software, but it will be rolled out progressively throughout the coming months to all BEV vehicles.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Polestar 37798.1.0 a recall?
No. A service bulletin 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 37798.1.0 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does 37798.1.0 cover?
The manufacturer filed it against 5 model years: 2025 Polestar 2, 2024 Polestar 2, 2023 Polestar 2, 2022 Polestar 2, 2021 Polestar 2. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
