Defect SummaryCertain sport utility vehicles, pickup trucks, and passenger vans fail to comply with the requirements of federal motor vehicle safety standard no. 135, ?passenger car brake systems.? some of these vehicles were produced with an out-of-specification brake hydro-boost housing relief valve bore.
Consequence SummaryConsequently, the valve o-ring seal may fracture. steering efforts may be slightly increased while braking or parking. under certain driving conditions, a fractured seal may require a slight increase in the applied brake pedal effort to achieve the same vehicle deceleration rate as prior to the seat fracture.
Corrective SummaryDealers are to replace the hydro-boost relief valve. the recall began on june 18, 2004. owners should contact cadillac at 1-866-982-2339; chevrolet at 1-800-630-2438; gmc at 1-866-996-9463; or hummer at 1-866-486-6376.

 I bought a 2003 hummer h2 brand new. since the day i got it had many problems, both electrical and mechanical. the steering is very hard and the breaking is ineffective at times. i showed them a copy of the bulletin on this website. they did not acknowledge any problems. the issue still persists. many electrical issues seat memory problems, mirror don't work..etc. eventually the electrical issues fixed. roof leaking water from the reading light on two occasions once because of sunroof issue and the second time because of the outside roof light. now most recently i have been having a problem with the check engine oil light comes on every 5 to 6 weeks and way before an oil change is due. this has happened at least 5 times so far. everytime the engine is missing oil. the dealer says that hummer allows the engine to burn one quart of oil for every 100 gals of fuel. i said what am i supposed to do when that light comes on. the service manager said pull off the road and check the oil. i said what am i supposed to do if the oil is low. he said add oil to the engine. i said so i have to drive with a couple of quarts of oil in the back all the time? the light comes on every 5 to 6 weeks. i said how many hummers have you sold? he said many. i said how many you know of do that? he said none. i said if none do that, why does mine do it? and if this normal why none of the others do it? the dealer refuses to acknowledge any leak of oil or any burning of oil by the engine!!!!!!! *nm
