I have an 2009 4.6 V8 with Tech package. 114k miles, everything has been good, only a couple minor hiccups plus the usual standard maintenance. I bought the car CPO in 2012 with 29k miles, so I've put the majority on it. Just standard maintenance other than listed below.
-thermostat stuck open at 38k miles. Took 4 days for dealer to get part in stock, covered under warranty, no loaner offered
-windshield wiper motor died at 85k miles. $550 to replace, took 4 days for dealer to get part in stock
-replaced original brakes pads at 88k miles and resurfaced rotors. Front rotors warped at 100k, replaced. Not a real gripe since I've never had brakes or rotors on any previous car last that long overall.
So my biggest gripe is that if something goes wrong with a Genny...the dealer isn't likely to have parts in stock since the car is "rare". And Hyundai being the budget brand they are, none of the local dealers offer loaners or rentals which is a pisser when it takes 4 days just to get the parts in. My wife is a 3x Subaru driver and both Subie dealers by our house offer free loaners.
And to chime in on faizal's observations above:
-my right rear suspension creaks when I go over a big, soft bump in the road and the suspension travels to full extenion
-I've got several windshield chips too doing mostly highway driving, so it's probably true about the soft glass
-my driver's seat cooling still works, but is definitely less effective. I've seen the mod about opening up the seats and installing some tubing to open up the ventilation pathways. The foam in the seat is definitely more compressed now than when I got it.
I plan on keeping this car until it dies...so hopefully a long time

I'd like to take it to 250k miles or about 5 more years.
