I actually like it very much. As far as functionality, my only complaints are the lack of storage in the first two rows and the woefully pathetic infotainment system. The EX stereo sounds fantastic but is lacking in the functionality department. I was so frustrated by the infotainment, I nearly returned it right away and replaced it with an Odyssey but the dealership group didn't have a Touring Elite in the color I wanted so I decided I didn't want to have to go through the credit process with another dealer.
Now, as much as I like it, it spends entirely way too much time in the shop. It's constantly in for repair. Kia's been ok to work with on some things and horrible on others. I've had to file three complaints with Kia corporate already and have even reported an issue with the headlights to the NHTSA as Kia is refusing to put anymore time into my issues. I see many Tellurides with the same exterior fit and finish issues that I've had repaired. Fit and finish have been about half of my issues. The QC at the factory seems poor.
It's been in for repair nearly 10 times in 28k. It's obviously always covered under warranty and always drivable but having to leave it for the day, that many times is inconvenient and not my expectation when I purchase a brand new vehicle. This is like my 5th new vehicle, never had anything require this much attention this early. I have a 7 year old Honda that has 3X the miles and has never required a repair. I just change the fluids, it's still on the original brakes. The Telluride sat outside in the cold last night, the brakes were squealing and clunking the first 5 minutes I drove it this morning. I don't have issues like that with my other two vehicles.
You'll probably love it. You could get a good one, you could get a bad one. Plenty of frustrated members on here with a number of different issues, some of which Kia has yet to resolve. So, it's not all peaches but when it's right, it's a very nice vehicle. That's why I say, yes, it's a nice car and yes, it's kinda junk too. I've had mine 16 months and I still think sometimes, "I can't believe this thing's a Kia, it's impressive." but on the other hand on that same drive, it might give me reason to think, "Ugh, well, this thing IS a Kia..."
