2025 Kia K5 Recalls, Issues & Maintenance

The 2025 Kia K5 carries 2 open NHTSA recalls — most recently covering software and roof and pillars. Owners report 5 recurring issue clusters, led by “OEM Pirelli tire sidewall bubble and blowout.” Kia uses Hyundai Motor Group's powertrains, so service intervals mirror Hyundai's. Kia Promise covers the first 3 years / 36,000 miles of complimentary maintenance. Kia owners with the Theta II 2.0L/2.4L (Optima, Sorento, Sportage 2011-2019) should adhere strictly to oil intervals due to known oil-consumption issues in Kia TSBs.

Campaign #25V351000 · May 27, 2025

Issue: Kia America, Inc. (Kia) is recalling certain 2025 K5 vehicles. A software error in the Power-net Domain Controller (PDC) may cause the parking lights to flicker.

Fatal crash history & reported problems

Occupant deaths in fatal crashes (FARS)

No occupant deaths in FARS 2010–2024 crashes are on record for this year and model. That is the census answer for the window, and it says nothing more than that.

FARS counts every occupant death in a fatal crash, whatever the cause — it does not mean the vehicle was at fault or defective. Counts are not adjusted for how many of each vehicle are on the road. How to read this number

Owner-reported problem signals

Separate from the federal fatality data above: complaints owners filed with NHTSA about this year and model. These are reports of problems, unverified, and are counted here only as signals.
