I've only got a bit over 2 months on mine, 1,500 miles. Like others, my ISG has a mind of its own. The green icon in the HUD comes and goes, completely independent of the green icon in the cluster display, which is completely independent of the green icon in the tach??? The dealer says Kia is aware of it and will likely have a software update to fix the problem - someday, but in the meantime he can't do anything other than leave the ticket open to remind them to keep checking on it.
On a slightly disappointing note - when I went to install a
dash cam and
radar detector, to get power from the overhead console wiring: First, remove the cover off the windshield rain sensor module to access the wiring. WTF!! There is no cover. As soon as you move the mirror out of the way, you are looking at the wires. THE COVER IS MISSING. Call the dealer and talked to the service manager. Don't have any on hand of course. Have to bring the car in (60 mi trip) to verify the missing cover? Made an appointment for 2 days in the future
with the service manager.
Appeared for my appointment 30 minutes early (never want to be late to those). What appointment? No appointment for me. The service writer would try to work me in - what's wrong? ISG has a mind of its own and works around 30% of the time. The icons come and go as you are driving down the highway and the off light, HUD icon, LCD icon and tach icon have nothing to do with each other, maybe all of them on, maybe none of them and maybe in any combination. Okay, we'll take a look at it, anything else?
Yes the cover on my windshield rain sensor module is missing. Hmmm. . . . Can you show me the cover? Duh! I could if it wasn't missing. The most I can show you is the hole where it should be. Okay. He looked at the hole and agreed the cover is missing. They will order it and it will take 2 business days. Since its a 60 mile trip, he will look at the possibility of mailing it to me. That was 2 weeks ago.
On the good side, I used 91 octane for the first 500 miles and then switched to 87 and the car loves it. I spend more time in city driving, but some in heavy traffic highway, (75 mph multi-lane). The total average so far shows 28.5 mpg, which I'm really pleased with.
