How to Reset the Oil Life Indicator on a 2015–2019 Hyundai Sonata

Which Hyundai Sonata model years does this cover?

These oil life reset specifications apply to every Hyundai Sonata built from 2015 through 2019 — the LF (7th generation), mid-size sedan. Nothing in this specification changes between those model years. Pick your year for the engines it offered, what changed that year, and the problems recorded against it.

What changed during the 2015–2019 Hyundai Sonata

• 2015Generation launch on the LF platform; Eco 1.6T added
• 2016Hybrid and Plug-in Hybrid trims join the lineup with the Nu 2.0L GDI hybrid powertrain
• 2018Mid-cycle facelift arrives; a new mid-range SEL trim is added with Blue Link telematics, SiriusXM, HD Radio, and a power driver's seat standard (base SE and Eco lose those items as standard equipment)
• 2018–2019Mid-cycle facelift: new front/rear styling, revised interior with digital instrument cluster option, Eco 1.6T dropped from some markets late in the run
• 2019Final model year of the LF generation; facelifted trim lineup and styling carry over unchanged ahead of the all-new DN8 for 2020

How do you reset the oil life on a 2015–2019 Hyundai Sonata?

5 steps, using only the controls in the car, the full sequence is above.

Do you need a scan tool to reset the oil light on a 2015–2019 Hyundai Sonata?

No. The procedure above uses the vehicle's own controls. A scan tool is only necessary if the reset does not take, which usually points at a different fault.

Why won't the oil light reset on a 2015–2019 Hyundai Sonata?

Almost always a timing problem in the sequence, a step held too briefly, or the ignition in the wrong position. Repeat it exactly, with the engine off and the key in accessory rather than run, unless the steps say otherwise. Pre-facelift (2015–2017) cars use the trip-hold method carried over from the YF generation; facelift (2018–2019) cars add a menu-based alternative in the digital cluster.
