Component: Fuel System, Gasoline > Delivery
Manufacturer: General Motors Corp.
Description:
On certain passenger vehicles equipped with 3800 v6 (l36) engines and certain delphi fuel pressure regulators, the regulators have a much higher than usual rate of fuel leaks. a leak can allow fuel to enter the intake manifold through a vacuum line. if the engine does not start when cranked, the fuel from the leaking regulator and a mistimed spark can cause a backfire.
Consequencs:
The backfire can rupture the intake manifold. the rupture of the intake manifold can displace a fuel line, pulling an injector out of place, and causing a fuel leak and possible fire.
Notes:
Dealers will install new fuel pressure regulators with improved diaphragms. the recall will be conducted in phased mailings. phase 1 began on june 30, 2004, and phase 2 began on september 30, 2004. owners should contact buick at 1-866-608-8080, oldsmobile at 1-800-630-6537, or pontiac at 1-800-620-7668.

Component: Exterior Lighting > Headlights
Manufacturer: General Motors Corp.
Description:
Vehicle description: passenger vehicles. these vehicles do not conform to the requirements of fmvss no. 108, "lamps, reflective devices, and associated equipment." the head lamp adjustment device horizontal adjuster may not move the head lamp reflector when the shaft is rotated in a normal manner during aiming.
Consequencs:
Driver visibility may be impaired increasing the risk of a crash.
Notes:
An insert containing instructions for optically aiming the headlamps will be provided to owners for the owner's manual. owners should follow the procedure in the insert for headlamp aim adjustment, rather than using the horizontal vhad indicator.

Component: Power Train > Automatic Transmission
Manufacturer: General Motors Corp.
Description:
Vehicle description: passenger vehicles equipped with 4t65e automatic transmissions. these vehicles fail to conform to the requirements of fmvss no. 102, "transmission shift lever sequence." a retaining clip, which secures the manual valve to the linkage of the transmission detent lever, can become loose under a combination of possible driver shifting maneuvers and allow the link to become disconnected from the manual valve.
Consequencs:
If the link disconnects, the driver's indicated prndl state may differ from the hydraulic state of the transmission. if the driver selects 'drive' and the transmission is actually in 'reverse', a vehicle crash could occur.
Notes:
Dealers will replace the manual valve/link assembly with a replacement manual valve/link kit, featuring a spring-type fastener.
