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.

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: Wheels
Manufacturer: General Motors Corp.
Description:
Vehicle description: passenger vehicles equipped with chrome plated aluminum wheels. some of these wheels have a mounting surface that was not machined correctly, causing the wheel studs to break.
Consequencs:
The tire/wheel assembly could separate from the vehicle, increasing the risk of a crash.
Notes:
Dealers will inspect the wheels and replace all wheels with date codes indicating that they may not have been machined correctly. the wheel mounting studs at any location where a suspect wheel was installed will also be replaced.
