Polestar filed this with NHTSA as a service bulletin dated Dec 13, 2025, received Aug 18, 2025, about the electrical system — 3 documents under this number. 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 owners reported
Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 595 complaints with NHTSA since 2015. 69 of them name Electrical System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
There was a recall due to the rearview camera not coming on when the car is put in reverse. My car was at the shop 3 times for this issue to be fixed and they are unable to fix it. Now the site says there are no recalls on my car. How do I get this fixed? They should be fined for letting this go for years and still not resolving it.

Common questions
Source: NHTSA, 49 CFR 579.5Is Polestar 37439 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 37439 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 37439 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.
