By Tim Gibson · 23 Mar 2026

The recently-launched Kia K4 hatchback has just been recalled in Australia due to a seat belt fault, according to a notice from the Department of Infrastructure, Transport, Regional Development, Communications, Sport and the Arts.It concerns 4817 units in the 2025 and 2026 model years. “The rear centre seat belt anchor buckle may have been incorrectly assembled,” the notice reads."As a result, the seat belt may not properly latch or operate as intended.“In the event of an accident, if the seat belt does not properly latch or operate as intended, it will increase the risk of injury or death to vehicle occupants.”A spokesperson for Kia Australia said there have been no reported incidents of the fault occurring in Australia yet. Owners of affected K4 models will be contacted by the brand and asked to make an appointment with a Kia dealer to have the rear middle set belt anchor buckle inspected, and replaced if needed, free of charge. The K4 was launched in Australia late last year and is available in hatch or sedan body shapes as a petrol-only model.It has made a solid impression in the market in its first few months and outsold the Hyundai i30 and Mazda 3 so far in 2026

My 2025 Kia K4 engine and oil lights keep coming on

Answered by David Morley · 09 Apr 2026

It’s possible that the same problem is causing both the check engine and oil light to light up. That’s because a low oil pressure or oil level light will sometimes trigger both the oil and check-engine lights. I assume the basics such as oil level (on the dipstick) have been checked.

Continuing to drive a car with a flashing oil light on the dashboard is asking for trouble, to be honest. This needs to be investigated and you might want to look for another dealership who can better manage this stuff.

Either way, it’s a dealership problem because this sort of thing should be covered by the factory warranty if there really is a problem. But even if it’s just a computer glitch that’s lighting the warning lights up now and then, you need to know what that is and put it right.
