Volvo filed this with NHTSA as a service bulletin dated Jan 30, 2024, received Jan 31, 2024, about the electrical system. It names 46 model years (2018–2024). 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.

Read by machine from the document NHTSA serves (4 pages), read Sep 30, 2026. A part number is shown only where it matches Volvo’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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.

2024 Volvo S60 · Electrical System · filed with NHTSA Aug 27, 2026 · ODI 11760181
After two days of ownership and 148 miles, the car threw a check engine light w/ the following message: "SLOW DOWN. The vehicle will reduce speed. Propulsion system failure." followed by, "Propulsion system service required.". This consequently causes the car to go into 'limp mode' unexpectedly while driving, drastically reducing speed.

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 36693.2.1 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 36693.2.1 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 36693.2.1 cover?
The manufacturer filed it against 46 model years: 2024 Volvo C40, 2023 Volvo C40, 2022 Volvo C40, 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.
