Without any warning, the engine began to misfire and stall out after starting from a green light. It only lasted about 10 seconds. After this, the engine quit misfiring and began to have an audible whine come from under the gear shifter.

After examination by a mechanic, in the lower portion of the engine a bolt holding in place one of the balancers worked itself free. The entire bolt was displaced from its original location and the threads were protruding out of the plate behind the flywheel in the area of the rear main seal causing a significant loss in oil. Upon further inspection after the engine was removed, multiple components appeared damaged as a result of th

Radiator has a 8 inch horizontal hair line crack that lets the coolant leak. The crack is on top right corner( drivers side). The radiator top is made from plastic that is prone to cracking due to framework bumping into it causing strain on radiator top which after time causes the top right corner to establish a hairline crack and cause the coolant to leak. Many Hummer h3 vehicles owners have complained about this issue of having hairline cracks in top right corner. Hummer has replaced several Hummer owners radiators at no cost, due to a design flaw that the top right radiator bumps into the framework causing stress on it and cracking. Gm has updated the radiator to accommodate for this issue, but has not showed interest in saying that this is a big issue. Why would they allow this to happ

I have been having security issues with this vehicle for the last 2 years. Keeps me stranded at times until the system resets itself. My hood is rattling and am afraid one day it will come off. Don't want to trade it in but may not have a choice. If companies are aware of these problems they need to fix them before someone gets killed or seriously injured. It is a total shame that consumers have to deal with all these problems and by the way paying high car or truck notes a month and having to deal with extra problems we don't need or want. Fix everything right the first time and there won't be so many complaints coming your way. I have taken my vehicle in more than once for recalls on this vehicle. Please do something about these problems before someone gets sued. Thank you for your time.
