Had mine 7 months now. I have driven 25,000 miles already. With the exception of bypassing the passlock system, cleaning up the fan really switch a couple times, soldering in the resistor into the heater adjustment wiring , it's been good to me. 18.6 miles per gallon. Cooper tires in great condition to. Took it to the dunes at Pismo Beach, Ca. and went everywhere the quads did.

 

2006 base\lux 123k with abs sensor fault and traction stabilize fail flashing on info center getting annoyed. Needing to order new wheel hub along with abs sensor. Uhhhh...... But on bright side, new shocks and trail duty bump stop be here tomorrow!

 

Mine just turned 100k still going strong.I have only to replace the thermostat and plugs so far. I have owned it cents 06 when it was new

 

Finally took it to a dealership they say it's the radio draining battery if parked for a few days - something I can fix. Sounds like wiring on the harness

 

I have a 2006 Hummer H3, with 171K miles, I replaced the trans at 160K but the engine is still original, and running strong!

 

My 06 base lux has 206 000 km something around what 150 or 160k miles? I dunno what others had replaced, but I have done both front hubs, brake rotors and pads, both CV axles as well as bearings and seals. I had cracked manifold so put on otp header and a k&n polished intake, lower ball joints, bilstein shocks, 2 windshields, windshield wiper assembly, rear high mount brake light, radiator, plugs, evap vent solenoid, tires, hood louver recall, fixed sunroof drains, replaced a battery,belt and tensioner.
And now am about to tackle another pair of lower ball joints, brakes again, inner and outer tie rods, control arm bushings, stabilizer bar links, and upper control arms!!!!!!!!!!!!!!!!!!!!!
But other than those couple minor issues!!! Lol I love my rig!!

 

2008 H3 Lux. 135k original engine and trans. Started a new job back in May with a 50 mile one way commute. Miles are adding up real quick. Currently dealing with my wipers only working on high speed.

 

I'll have mine for 10 years in a few months and have 252,000 miles. I've never had any major problems with mine and only had to replace the battery, belt and a few minor things but other than that it's been the best vehicle I've ever had and runs just as good or maybe even better than the day I got it.

 

86,000 on 06 H3 Base, no transmission or engine issues in my 3 yrs of ownership with 60,000 when bought. From memory so far I have changed the battery, fan motor resistor, CD player needs to be replaced (wont eject), airbag light on, parking brake broken, just recently replaced shocks all around and a lower ball joint. All total im very happy with the relibility and its been a great experience.

 

hi everyone, my 06 h3 just turned 280,000 km and still going strong
