Volvo bulletin 37528
What it saysThis is a Tech Journal Text Plus 1 MP4 attachment If a customer complains about an exclamation mark on the connectivity symbol, please follow the advice under "Service". NHTSA’s full summary ↓
Volvo filed this with NHTSA as a service bulletin dated Oct 22, 2025, received Nov 17, 2025. It names 2 model years (2025–2026). 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 Tech Journal Text Plus 1 MP4 attachment If a customer complains about an exclamation mark on the connectivity symbol, please follow the advice under "Service". After v1.7.1 SW, it is possible that the exclamation mark in the connectivity symbol is present intermittently, regardless of good or bad internet connectivity. It does not depict the true status of the internet connection. This is a known issue and will be fixed in the upcoming Software release. The software version is to be determined and this TJ will be updated accordingly. Please see attached video TJ_37528_1 for reference.

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 Volvo 37528 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 37528 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 37528 cover?
The manufacturer filed it against 2 model years: 2026 Volvo EX30, 2025 Volvo EX30. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
