1. Radiator: The transmission cooler is connected to the radiator. The connections will fail after .... 30, 40, 50K+ miles. Upgrade your tranny cooler to an aftermarket unit.

2. Transmission: If these connections fail (from #1), they will allow radiator fluid leak into the transmission and vice-versa and will cause the radiator and transmission fluids to mix. You will see a stawberry milkshake like fluid in the radiator reservior. This will cause your transmission's 2-4 band to wear out and eventually the entire transmission will fail. When it happens, your tranny and radiator and reservior have to be replaced which will run about $7000.00 at a Hummer Dealership.

3. Idler and Pitman arms will fail after about 20, 30, or 40K+ miles. these arms are NOT designed for 35+ inch tires. They are designed for stock Suburban wheels/tires. If you have a newer H2, you will need to get the $214 Cognito kit to prevent early failure. If your warranty is out, buy the Idler and Pitman from ebaY or any PepBoys or AutoZone or Kragen and the Cognito kit. This will prevent abnormal tire wear in the long run. My dealership wants about $750 to 800 to replace just the arms.

4. I have heard of H2's front wheels falling off the truck while running.

5. H2's head lights suck. HID kits are available on ebaY for about $180 with hi/lo beams.

6. I have heard of the speedometer cluster fails after 20, 30K miles.

7. ?

So far...Only #6. Being replaced right now!!!
