While driving on a city street at approximately 40 MPH the vehicle started making a loud noise (similar to the sound a dirt bike engine makes). The sound became loluder when I pressed the brakes. I took the vehicle to the repair shop and was notified that the hydrobooster failed resulting in a steering fluid leakage.

Power steering fuel leakage tak gauge failure
Driving thru a heavy rain storm at 50 MPH in the left lane of a three lane highway and the windshield wipers stopped working at about a 1/4 of the way up...pulled over as soon as I could ...did not panic... Could not reset wipers...had to drive home off the highway for 30 miles with no wipers...thank god for rain-x on my windshield...googled h2 recalls and found # 08243 from gm on 9/9/2008 for the exact same issue...called gm and was told that my VIN number was not part of that recall even if it was the same issue??? Sorry, nothing they can do...wtf thankfully there was no crash but it could had been a mayor crash...
My vehicle's warranty which I purchased separately had just expired but I still went back to dealer as the noise I had reported to them under warranty was now more apparent. Turns out it was due to broken off exhaust header bolts.now I am out of warranty, dealership will not fix. I have 1 broken on drivers side and 3 on passenger side. Now my check engine light is on showing an oxygen sensor failure or catalytic converter. After researching the internet this problem is affecting thousands of people. Something needs to be addressed !!
Front windshield wipers and washer operate on there own.
Transmission cooler defect allows glycol to enter transmission. Transmission overheat condition occurs filling the inside of the vehicle with a toxic gas. Hot transmissions can also catch on fire. This is a known condition; gm issued an alert to dealership service departments but no recall has occurred.
Speedometer slowly stops working. Speed reading will decrease to zero while traveling at highway speeds & around town. At first happened periodically now happening more often.
While driving my 2005 h2 hummer in a rain storm the windshield washer motor came on and started spraying water and would not stop until the motor quit working. Thank god I did not wreck. After checking other sites and complaints this looks like a defect not only in 2003 models but 2005 models as well.
Brake pedal was pushed in to shift from park to drive. With brake pedal still firmly depressed, as soon as vehicle was shifted into gear vehicle began to roll forward. Brake pedal felt very hard and whining noise was coming from engine compartment. Vehicle slowly stopped after driver's full body weight was put on pedal. There was nothing under the brake pedal and the brake fluid level was checked and found to be appropriate. Vehicle was left to run for a bit and was tested at low speeds. Problem went away as mysteriously as it arrived.
Tl*the contact owns a 2005 hummer h2 sut. While driving 20 MPH, the contact noticed wiper fluid releasing on its own. He took the vehicle to the dealer and they stated that the wiper motor control module was retaining moisture and caused the motor to fail. The dealer estimated the repair cost at $500 because the VIN was not included in the federal safety agency campaign id number 08v456000 (visibility: windshield wiper/washer: motor). The failure mileage was 72,000 and current mileage was 76,000.
