Hyundai warranty extension TXX8
What it saysCertain 2013 – 2019 model year Santa Fe/Santa Fe XL vehicles equipped with 3.3L Lambda II GDI engines may experience abnormal engine noise or engine damage. NHTSA’s full summary ↓
Hyundai filed this with NHTSA as a warranty extension dated Feb 11, 2026, received Jan 4, 2025, about the engine — 6 documents under this number: 26-EM-002H DCS, 26-EM-002H TSB, 26-EM-002H DN, 25-EM-008H TSB and 2 more. It names 4 model years (2016–2019). A warranty extension 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 it applies to, as NHTSA’s summary states it — build dates and equipment as the manufacturer filed them. The dealer checks the VIN and the build date on the door jamb; a vehicle outside the window is not covered by this bulletin.
Certain 2013 – 2019 model year Santa Fe/Santa Fe XL vehicles equipped with 3.3L Lambda II GDI engines may experience abnormal engine noise or engine damage. At Hyundai, we are committed to providing vehicles of outstanding quality and value.

Eligibility for this warranty coverage is determined upon an inspection of the vehicle’s engine.

Read by machine from the document NHTSA serves (32 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.
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 4 model years this bulletin names have filed 2,299 complaints with NHTSA since 2015. 1,454 of them name Engine — 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.
On the 2017 Hyundai Santa Fe, the 212 owners who gave an odometer reading for Engine reported it at a median of 72,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

On September 22, 2026, my 2019 Hyundai Santa Fe XL experienced a sudden engine stall while I was stopped at a traffic light. The engine unexpectedly lost power, the steering wheel became extremely difficult to turn and appeared to lock, and the oil pressure, battery, and check engine warning lights illuminated.

I bought my car in july of 2016. Since then I had issue with the acceleration. Sometimes car takes longer to start from the stop position and when it starts, it just accelerates. On other occasions, the car feels like stalling while driving and then pick up the speed again.

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 Hyundai TXX8 a recall?
No. A warranty extension 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 TXX8 repair free?
A warranty extension 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 TXX8 cover?
The manufacturer filed it against 4 model years: 2019 Hyundai Santa Fe, 2018 Hyundai Santa Fe, 2017 Hyundai Santa Fe, 2016 Hyundai Santa Fe. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
