My girl's 2010 auto has 13,000 and no problems at all.
Mine has 46,300 as of today and I am smelling coolant, but no leaks detected. Coolant is still crystal clear red, but levels are low. Will look into this, since heater core is fine, bellhousing dry, etc... No other problems. No oil burning at all, but I do notice a little more "smoke/steam" coming from the exhaust when I rev above 4000K (passing on highway) - no smells or soot.
My Dad's 07 JKU Rubi has 116,000 on it. Last month he FINALLY replaced the brakes and water pump. Just yesterday he found out that his e-disco motor fried and the light keeps flashing. He never used it and it just flashes the light. Dealer wanted 1,700 for it and as of now, Dad is just ignoring it. The Jeep still starts and runs like a f**king champ on the original battery. Eats about 2 quarts of oil every 3000. It runs like a luxury SUV- nice and smoooooooth!

A little over 105,000 miles.
I give my JK an "A" to "A+" rating, compared to my previous vehicles maintenance and repair costs.
Very few issues over the years:
- Steering stabilizer leak. Replaced under warranty. (30K?)
- Steering clunk/knock - I lube as necessary. (45K?)
- Passenger rear brake caliper froze. Rear pads replaced too. (60K?)
- Gas tank had to be replaced under warranty. (90K?)
- Passenger Front u-joint needed replacement. (90K)
- New shocks installed at 100K.
- Weeping water pump gasket. Just watching it. (current mileage)
Everything else except for plugs, fluids and filters, is stock.
The motor seems to burn a quart to quart and a half of 5w20 every 4-5000.
It burns less if I run 5w30. More than I like, but not a big issue for me.

Main bearing was going out at 32k miles. A new shortblock was installed and it's running great now. Never had any oil consumption issues. Mine was a mid year 2008 FWIW.

08 2dr @ 55k. Began burning a little oil around 30k but then stopped. Not sure what's going on there?? So far so good (knock wood). No real mods. Ran a CAI for a while but back to stock now. Wish it had more power, but oh well.
