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.

Manufacturer: General Motors Corp.
Description:
Vehicle description: passenger vehicles. the brake booster to pedal assembly attachment nuts may be loose.
Consequencs:
If these nuts are loose, the brake pedal may be low, the assembly may be loose, the brakes may not release, and if the nuts back completely off, braking may be lost. also fume and water intrusion to the passenger compartment can occur.
Notes:
Dealers will replace any missing brake booster to brake pedal assembly nuts and tighten all four (4) nuts to specified torque.

Manufacturer: General Motors Corp.
Description:
Vehicle description: passenger vehicles. these vehicles may have been built with incorrect front brake rotor, brake caliper assembly, brake pads, and caliper mounting bracket on either the left or right side of the vehicle.
Consequencs:
A vehicle with this condition can pull to one side during a braking maneuver. in addition, vehicle stopping distance could be increased.
Notes:
Dealers will inspect for correct brake parts and replace any incorrect rotors, caliper assemblies, brake pads, and caliper mounting brackets.

Component: Visibility > Windshield Wiper/washer
Manufacturer: General Motors Corp.
Description:
Vehicle description: passenger vehicles. some of these vehicles fail to comply with requirements of fmvss no. 104, "windshield wiping and washing systems." these vehicles have a wiper system microprocessor that is susceptible to voltage transients, which can cause a "latch-up" condition in the system controller.
Consequencs:
If microprocessor "latch-up" occurs, the customer will not be able to operate the system in both the lower and high-speed modes required by the standard.
Notes:
Dealers will replace the windshield wiper motor cover which contains the microprocessor.
