Volvo bulletin 37235
What it saysThis is a Technical Journal: Changed front fog/cornering lights behavior. NHTSA’s full summary ↓
Volvo filed this with NHTSA as a service bulletin dated Feb 28, 2025, received Mar 27, 2025, about the exterior lighting. It names 63 model years (2016–2025). 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 59 model years this bulletin names have filed 1,321 complaints with NHTSA since 2015. 12 of them name Exterior Lighting — 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.
Blindingly bright passenger-side map light came on for no reason, illuminating the car and startling the driver AND other nearby drivers (it was night). Light would not respond to touch-sensitive on/off control. Had to cycle dome lights (another distraction and even more light) to get light to turn off
2024 Volvo XC40 · Exterior Lighting · filed with NHTSA Jul 7, 2026 · ODI 11748717
I ordered this vehicle brand new in October 2022. I took delivery May 1, 2023. The problem presented itself instantly the first moment I drove the car at night. On low beams, the headlights project a very large "V" that is cut out of the upper left hand corner of the projected headlight beam.
2023 Volvo V90 · Exterior Lighting · filed with NHTSA Dec 28, 2023 · ODI 11562437
Rear taillight failure due to moisture incursion. No message appeared, but light failure was observed less than a month ago. Car is in for regular service now and item is being replaced at great personal expense, since it will not pass required safety inspection until repaired.
2019 Volvo V90 · Exterior Lighting · filed with NHTSA Jun 25, 2025 · ODI 11669217
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 579.5Is Volvo 37235 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 37235 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 37235 cover?
The manufacturer filed it against 63 model years: 2025 Volvo EC40, 2025 Volvo EX40, 2025 Volvo S60, 2024 Volvo S60, 2023 Volvo S60, 2022 Volvo S60 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
