My 2006 H3, VIN falls within the head issue (105500 miles now) with adventure package has been pretty solid. Zero issues until around 2014, P305 cyclinder 5 misfire. Replaced spark plugs and coil packs. I had a hairline crack in my radiator, replaced that around 2013. Passlock issues began around 2015. Replaced the ?ignition cylinder? sensor and it has been fine ever since. Encountered p0442 small evap leak, replaced a evap canister, code still comes and goes. I clean my moon roof drains yearly. Replaced battery terminals a long time ago.
Overall it has been pretty good.

Right now I'm just above $200. per month AVERAGE, for purchase/maintenance/repairs.

I've abused my H3, overloaded many times, driven it like I stole it, driving slide-ways in the snow, jumping curbs off road etc, yet still starts, runs, and drives like new.

 

i have an 2006 with just over 94K miles, runs strong, i did the usual deferred maintenance items, on it, tie rods, ball joints, cv axles, maf, throttle body cleaned, vvt solenoid, battery, afew other items, replaced a bunch of light bulbs in the dash etc. she runs good getting upwards of 18.6 mpg running colorado mountains at over 9000 ft. everything works, no squeaks, with the adventure package she is very nice to go ofroad with.

 

Bought mine last year (H3 Base, 145k mileage), have loved every wrench turning minute of it, currently looking for the rare and elusive well cared for Alpha to maybe upgrade.

Granted i knew going into it that i had to do the CV axles due to age and performance and a much needed expert inspection before i dove into this project

So far in the last year of ownership i've done:
Air Doc Intake
2 Front Wheel Hubs
2 Front Cv axles
Thermostat
Battery Terminals
Underbody coating
KYB Shocks front and rear

this month i plan to do:
Tie rods and etc
spark plugs and etc
level out front end.

i've put probably close to $1200 in 8 months, with another $200 this month, then its onto the exhaust and getting the much sought after roof rack setup.

I drive this every day with the Serv 4wd error on the dash after long drives. i have no idea how to make it go away haha.

 

If you're squeamish about taking out the dash, make sure you get the H3 and not the H2

 

Besides typical Tire pressure code flash, my 08 H3 is well maintained at 115,000. Interior is well kept and small issues are easily solved because of the robust online support community. I would recommend the H3 for someone looking for a nice 4x4. Turning and parking Lot is a treat, fits anywhere 😁💘. Usually you can find nicely kept specimens in the wild because the initial investment was rather steep so the thing is not trashed generally. I think I may buy another.

 

I love mine and it’s the 3rd one I have owned.

 

My 2009 Alpha(105k miles) has come with a collection of little issues. I bought it about 10k miles ago with a salvaged title from a fixable front in collision. The "totaling" part of the accident was a bend in the front of the frame, which was straightened out and now its flawless. Got it for a steal so I don't mind a few little issues.

• Corroded Fuel pump relays (easy fix)
• Bad fuel rail sensor(took for ever to find, but after the fix she runs like new.)
• leaky sunroof from clogged drains
• Possible PassLock issue. Occasionally it will fail to start, but in 5-10 minutes it'll start up.

I don't see many people in this thread talking up the benefit of the 5.3, but man is it amazing. Towing is easy, the extra power for climbing is great. I pulled a boat once in the past 10k miles I've had it. It has enough torque and low enough gearing that If you lock the Diffs, and put her in 4 Low, you don't even have to press the gas to pull a bass boat out of the water and up the ramp. I love this truc...errr hummer.

 

Mine finally died. 2007, 198K Miles, Transmission blew. quotes from 2-3k to fix, I just couldn't put more money into it unfortunately. Was only able to trade in for $2k at the dealership as is.

 

Similar experience here. I have just under 200k miles on my ‘06. It’s been stout; however, I had to have the transmission rebuilt about 20k miles ago. Not too bad for a 14 y/o daily driver...
