PE07013	GENERAL MOTORS CORP.	03/12/2007	07/10/2007	FUEL PUMP MODULE LEAKS GASOLINE
	Odi has received reports that the fuel pump module leaks fuel and or vapor underneath the vehicle.gm states, the failure mechanism is corrosion of the fuel pump module flange which may lead to a fuel leak.corrosion of the fuel pump module flange is the result of the vehicle operating in a corrosive environment.odi has upgraded this pe to engineering analysis (ea07-009) to further assess this issue.
EA07009	GENERAL MOTORS CORP.	07/10/2007	08/28/2008	FUEL PUMP MODULE LEAKS GASOLINE
	During the course of this ea investigation, odi observed that the majority of the complaints (88%) and warranty claims (94%) were reported for vehicles that are registered for use in the salt belt region of the us.this area includes 20 states in the northeast, mid atlantic and the midwest regions and the district of columbia.consumers in the salt belt region reported to odi that they could smell fuel vapors in their vehicles while driving.upon further examination of their vehicles, they discovered that fuel vapors were coming out of the top of the fuel tank. this condition is caused by corrosion of the return and sender lines of the fuel pump module.water and road salt collect on top of the fuel pump leading to small pinholes appearing on the fuel lines.fuel may leak and collect on top of the module and/or spill onto the ground.the data evaluated under this investigation reflect a relatively low frequency of occurrence that largely arises in salt belt states.gm has extended the warranty on the subject component to ten years or 120,000 miles.further use of agency resources does not appear to be warranted at this time; accordingly, this investigation is closed.the closing of this investigation does not constitute a finding by nhtsa that no safety-related defect exists.the agency reserves the right to take further action if warranted by the circumstances.for additional information select document search.

	Exhaust bolts have broken on the exhaust manifold, this vehicle has the v8 engine. dealer explains that this needs fixed as carbon monoxide could enter the passenger cabin. there was an accident with the vehicle a year ago, i contacted my insurance company to see if it was related to the accident. they claim that it is not related to the accident and that gm vehicles model year 2000 to 2007 with this 5.3 v8 engine have reported these bolts breaking and informed me to contact gm about reimbursement for repair expenses. i do not have the $2000 for repairs and am concerned about the safey of my family while in the vehicle.
