Hyundai service campaign 9B6
Hyundai filed this with NHTSA as a service campaign dated Feb 14, 2025, received Jan 21, 2025, about the vehicle speed control — 3 documents under this number: 25-01-003H OL, 25-01-003H DBP, 25-01-003H TSB. It names 3 model years (2021–2023). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationCertain Elantra Hybrid (CN7 HEV) vehicles may exhibit an intermittent condition where the cruise control set speed could gradually increase when the driver releases the cruise control set speed adjustment switch. The cruise control set speed is clearly displayed on the instrument cluster, provides visual indication to the driver when the set speed is adjusted, and remains adjustable by the driver at all times. The cruise control can be cancelled by normal methods, either by pressing the cruise control switch or depressing the brake pedal. Follow the procedure in this bulletin to update the Hybrid Control Unit Low Voltage DC/DC Converter (HCULDC) system software to resolve this condition.

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 Hyundai 9B6 a recall?
No. A service campaign 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 9B6 repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does 9B6 cover?
The manufacturer filed it against 3 model years: 2023 Hyundai Elantra, 2022 Hyundai Elantra, 2021 Hyundai Elantra. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
