Read by machine from the document NHTSA serves (4 pages), read Sep 30, 2026. A part number is shown only where it matches Hyundai’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.

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.

The vehicle was already running and in Drive. When I pressed the accelerator pedal to accelerate further, the vehicle would not accelerate. The RPMs did not increase and vehicle did not respond. No warning lights appeared. I had to press hazard lights coast to shoulder and turn vehicle off and on to regain power].

Common questions
Source: NHTSA, 49 CFR 579.5Is Hyundai 23-01-080H 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 23-01-080H 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. Every Hyundai warranty extension on file lists the ones Hyundai has filed.
Which vehicles does 23-01-080H cover?
The manufacturer filed it against 2 model years: 2023 Hyundai Santa Fe, 2023 Hyundai Tucson. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: 2023 Vehicles: built 29 Jun 2023 – 3 Jul 2023 — the build date is on the certification label in the driver’s door jamb.
