There’s always the temptation to just google this stuff. Problem with that these days is that you don’t know whether the information you dig up is from a trusted source or not. Also, you could be unwittingly looking at the specifications for the same car as yours but built for a different market where fuel quality and engine specifications are different to here. A much safer bet is the check the owner’s manual that came with the car (assuming it’s still in the glovebox).
In any case, I contacted Kia Australia who told me that your car would be fine on 91-octane fuel. Which is to say you can certainly pay more for 95 or 98-octane ULP, but your car won’t drive any differently, use less fuel or be any more reliable. So, 91 it is.
My 2017 Kia Carnival is out of warranty can I still claim any repairs?
Generally speaking, once a vehicle is beyond its warranty period (or distance travelled) that’s it as far as the manufacturer’s responsibilities lie.
The exception is if you have experienced a problem while the warranty was still current, logged that fault with your dealer or manufacturer, but the problem has still not been fixed. That’s what’s called a pre-existing fault and technically, it’s still covered by the factory warranty, provided it would have been a warranty job within the statutory warranty period.
Warranty law doesn’t really differentiate between types of faults (electronic, structural or mechanical). But if the dealer knew of a warranty problem while the car as still within warranty, then that dealer (or the manufacturer/importer) is legally obliged to fix it.
My 2026 Kia EV5 had a 'power limited' message appear
According to Kia, this message is most commonly displayed if any of the following conditions are present:
The temperature of the EV battery is too high or too low
The temperature of the electric motor is too high.
The smart money suggests you should report this to the dealership either now or at your next service. That way, the Kia technicians can figure out what happened and how to prevent it happening again.
Along with the warning on the dashboard, the car will also limit its performance to protect major systems. That’s why it refused to accelerate and would not go beyond a certain speed.
