Kia are bastards when it comes to anti consumer practices, my 2012 Kia had an airbag warning light come on right before it’s MOT and my usual garage said they couldn’t read the fault code, I tried specialised diagnostic readers and even borrowed a garage spec one from a neighbour and still couldn’t get anything from it.
In the end I had to take it to Kia themselves and get them to read the fault code for £130, turns out the fault was exactly what everyone thought it was but couldn’t confirm and now they want £750 to replace a single airbag module that needs to be coded to the car once it’s installed. My car has been in their garage since the start of January and there’s still no sign of the part arriving yet but I can’t install one myself because of the fact that only Kia can recode it to match the car.
