Volvo filed this with NHTSA as a service bulletin dated Sep 8, 2023, received Oct 16, 2023, about the power train. It names 24 model years (2016–2018).

Quoting the number at a service desk can save a diagnosis.

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.

What owners reported
Source: NHTSA complaint databaseOwners of the 20 model years this bulletin names have filed 555 complaints with NHTSA since 2015. 8 of them name Power Train — 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.
I have had an unresolved issue with a persistent vibration throughout the vehicle while at 50mph or higher. This seems to be a universal issue with volvos post 2017 across models. I have attached a copy of my emails and non-responses from Volvo dealer reps who have claimed it is normal behavior.

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 TJ3666530 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 TJ3666530 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 TJ3666530 cover?
The manufacturer filed it against 24 model years: 2018 Volvo S60, 2017 Volvo S60, 2016 Volvo S60, 2016 Volvo S80, 2018 Volvo S90, 2017 Volvo S90 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
