my Hummer h3
 

Just got my 2007 h3 3.7 and so far all is good should I get ready for any problems

If you don't know the service history, the first thing I would do is change ALL of the fluids, clean the throttle body and MAF sensor.

Thanks for the information will get that done

Things to check
 

I'd take a look around the forums, a few searches should pull up a few threads regarding common problems.

Along with changing out fluids, I would;
-Check radiator.. it commonly develops a hairline fracture across the top.
-Check CV seals up front. Seems like the tend to leak.
-Inspect your moonroof if you have one. The drain plugs often clog, potentially causing wicked electrical issues.
-Inspect/replace battery terminals. Stock terminals are absolute junk and will eventually cause problems down the road.
-Make sure your AC operates properly. They just issued a recall regarding the blower motor resistor harness. Look into the recall.

Just a quick list of things I could think of. Enjoy!

spend some time reading many posts here and learn a lot.

For the 1st year I just tried to drive and smile. Pretty much made it.

So far it's great to drive. It has a miss but I hope it just needs a tune up. Otherwise in good shape.
Thanks for all the information. Well definitely enjoy it
