I'm hoping someone can help me with where I go with this. I have had my KIA CEED for 6 months, it's a 2021 ex-demo with 7900 miles on the dash. I got an email from KIA about a software update to the Hybrid system and I was to book it into the main dealer. I had previously purchased a service plan for the car and as it was going in for the update I also booked the first service. I took the car to Arnold Clark Kia in Glasgow on 15/04/22 and was told it would be back with me later that day. I was called 5 hours later to be told there had been a problem with the update. It was then explained to me that the mechanic doing the work pulled the plug out of the car halfway through the update as it had frozen. This caused a couple of the super chips to blow on the car and they would have to order them, with no date of arrival. I then asked for a courtesy car as this was the garage's fault, but they refused and said it was KIA's software fault. I got in touch with KIA and guess what, they wouldn't give me a loan car either as they said it's not their policy to give out courtesy cars.I went back to Arnold Clark and they said as a goodwill gesture they would give me a CC for a couple of days so I could get to work and try and arrange my own transport. I got a 3-year-old Picanto that hadn't even been cleaned inside or out and stank of smoke, I had to take it as I need a car for work. I then called KIA 3 times to try and get a car, and eventually 4 days without a car I got one from Enterprise, a Peugeot 3008 petrol. Now I travel 70miles in total to my work, and the fuel consumption in this vehicle is truly awful, around 35-45 MPG. Back to the super chip. I have had 3 different dates for these chips to arrive at Arnold Clark and KIA, and yes they have all come and gone with no chip, I've even been told it's been lost twice in transit. I called KIA again and spoke to a guy called Micheal in customer services, and wow what a patronising guy he was. I was asking for a date of repair on my car and if I could possibly change the courtesy car, but he kept talking all over me with the same words that this wasn't KIA's fault and I was lucky to get a courtesy car as they are under no obligation to get me one, I must have heard this about six times from him whilst I was trying to explain that it also wasn't my fault.I eventually gave up as I could feel myself getting angry and don't like to lose it with people on the phone. Michael eventually said he would pass me through to KIA rental, I never got passed through and the line went dead. I called back the next day and was advised that if I wasn't happy I was to hand back the car to enterprise as KIA are under no obligation to provide me with one. I have given up at the moment as I'm at an impasse with this and hence the reason for joining this forum to see if anyone has ever had anything like this with KIA. Sorry for the long post but I'm at my wit's end with this. Now I fully understand the problem with getting the part, but KIA's attitude with dealing with this is awful.
