I have done about 215 miles up and down a very quiet stretch of motorway. Ten miles to roundabout, turn around back to next roundabout keeping car at about 2500 RPM with no sign of the light going off. No sign yet of performance dropping but hitting me hard in the pocket.
I have decided to run the car as I run it and if it breaks down then get recovery to uplift. There is no point in me wasting money to solve a Kia issue.
Overall, I would not let this put me off the car as it is fantastic and I am sure Kia when it happens enough will issue some sort of recall. Having worked many years ago in a large car manufacturer warranty department they wait until a certain amount have developed the fault.
My suspicion is they already know and maybe cars after a certain chassis number will have a different type or manufacturer of GPF. I cannot see Kia wanting to harm there brand name with something like this.
I will keep updated.
Max.
