Questions from a potential new H3 owner

I'm heading to a dealership to take a look at an H3 tomorrow - anything on the vehicle that I should be aware of or look out for? Also, any general comments or wisdom for a new H3 owner?

It's an '07 base with ~40K miles. I know low-mileage models are getting pretty hard to find these days, so I may end up owning it even before this post gets any replies...

they're pretty robust, 07 and up had the larger 3.7 5 cylinder motor. If you do any off-roading, you should look for an adventure package on the vehicle which gives you a rear, electric locker and a 4:1 low range transfer case. Out side of that, condition is everything since there are two types of Hummer owners... mall and offroad (oh yeah, three if you include chromosexuals like Twin).

Unfortunately, I'm more in the "mall" category. However, I visit friends in an area that can get some serious snow. A couple winters ago, I remember being nervous driving around in my 4x4 S10, so I was hoping to get something a little beefier when it died. Robust sounds pretty great to me :thumbs:

Then there must be four groups.
I don't go to the mall if I can help it and I don't chrome anything.
I do however operate a small business daily with Happy my 07 h3 actively playing tow pig, parts hauler, office, phone booth, storage facility and so much more. ...
I us it as a work truck.

If a hummer is what you desire, do a lot of reading and lurking 1st here and elsewhere.
Purchase well informed and prepared. Also, when the truck ceases to fulfill your requirements move on.

If you can spring for it I would look for an 08 H3 alpha. It has the 5.3l v8 which is a nice upgrade as compared to those 3.5 and 3.7l in line 5 cylinder engines. Check for sunroof leaks, make sure the AC and heat knob functions properly. Also make sure all of the speakers are working, parking brake check...
Also you should probably change all the fluids after you buy it... I mean all...

Try to get a good extended warranty.

Look for previous damage.
When I was H3 shopping one dealer let me take an 07 H3 on a 24 hour test drive. It drove pretty good for have like 80k miles on it. But when I looked for previous damage I found out that it had been rear ended. You could tell by some sloppy welding slag left behind between the rear bumper and the body of the truck. Which obviously wasn't done at the factory. They usually don't have sloppy welds.
But the dealer was selling it as a one owner and no accident vehicle so I walked away.

That's just a few things to look out for.

If you are not confident in your car inspection skills, I highly suggest that you get an independent inspection on the vehicle before you hand the dealer a check for $15k-$20k. Expect to pay $100-$200 for a good inspection.

I hope this info helps you.

Edit: also check and see if all of the 4x4 controls on the center console work properly. To do this put the truck in N first.

Yup, what they said. If you can get an Alpha with the V8 you won't regret it the gas mileage difference is minimal and even in bone stock form these are heavy beasts. The more power you can get the better. Look through the threads on this forum. There are more than a handful with pictures to show you where the control buttons are if it has the adventure package with the locking diffs. 08' and up have a cast iron front diff which is a VERY good thing. Look at the vehicles car fax. You want to know if it's been owned in the north-northeast. Lost of rust in the underbody will also clue you in to that as they use stuff during the winter months that is corrosive. Get the dealer to put it up in a lift. With the skid plates off you can get a good eye on all the seals to check for leakage. Look at your axle seals. Also peruse the forum for pictures of a worn out front crossmember bushing. We have a vendor on here who sells replacement cross members on here with upgraded bushings. Familiarize yourself with how the 4x4 controls work and test them out on the test drive. Check for hard shifting on the transmission. As stated above, be prepared to swap all fluids aka front and rear diffs, transfer case, transmission, motor oil, radiator, etc. peruse the forum for failed radiators so you know what to look for. This is a weak area and the transmission cooler is internal on the radiator. The radiator takes dexcool and if the radiator fails it has a nasty habit of cracking and mixing the dexcool with the tranny fluid and killing both the motor and transmission. Check the sunroof for leaks and clogged drains. Be prepared to swap out your battery cable terminals. These are a source of a lot of electrical gremlins. Check the front drive line boot and make sure it's not torn. Check for sagging rear leaf springs. Most of these things are general wear and tear items. They are things you'll more than likely be faced with over the life of the vehicle. If previous owners wheeled it they are more likely. Check and see if it has OEM wheels, if so, what tire size? Has the front end been leveled? If so, does it ha e extended shocks and bump stops? That's all I can think of. Happy hunting.

We don't deal with salted roads here in So Cal but I know it can cause a lot of hidden issues. Other than rusty parts these are pretty easy to work on and you will have lots of help here from forum members.

Thanks, guys! I'm now an H3 owner and glad to be part of the community.

I couldn't find anything wrong with it, and my state does safety inspections to check the condition of the vehicle (everything passed). The dealership also ran it through their shop to look for problems. Carfax is clean, and it spent most of its life in Florida. I did two test drives, including highway. All controls, transmission, engine seemed decent. I was as thorough as I could be. It's no Alpha, but it seemed to be powerful enough for me.
