Select Your Model Year

Every model year here opens into its own interval-by-interval breakdown, and each one carries its own recall history too — something worth checking whenever you’re next in our Hattiesburg bay.

How the Schedule Has Changed Over Time

2025 — Facelift + Base-Engine Swap
Base Engine Moves From Turbo to Naturally Aspirated Engine Change
Alongside Star Map LED lighting, dual 12-inch displays, and a new rotary shifter came a swap under the hood: the 1.6L turbo base engine gave way to a 2.5L naturally-aspirated unit (the GT trim holds onto its 2.5L turbo). That pushed the spark-plug interval on base trims from the shorter turbo cadence (~48,000 miles) out to the longer NA figure of 96,000 miles.
2024 — Minor Update
Heated Front Seats on GT-Line FWD Maintenance
Just a feature addition, nothing styling- or mechanically-related, so the schedule stayed exactly as it was.
2021 — New Generation
K5 Replaces the Optima New Gen
This is where the 3rd-generation DL3 K5 took over from the Optima, launching with a 180-hp 1.6L turbo base and a 290-hp 2.5L turbo GT. Routine oil and rotation lands at 8,000 miles or 12 months, brake fluid gets replaced at 48,000 miles or 48 months, and the first coolant change comes due at 120,000 miles.

K5 Maintenance FAQs

Where's the K5 Schedule for My Year?

Pick any year between 2021 and 2027 above to pull up oil and rotation, filters, spark plugs, and coolant details for that specific model year.

Does the K5's Engine Change the Service Intervals?

It does — the GT trim's 2.5L turbo calls for spark plugs around every 48,000 miles, while the 2025-and-later base 2.5L naturally-aspirated engine stretches that out to roughly 96,000 miles.
