NHTSA Campaign #04V090000 FUEL SYSTEM, GASOLINE:DELIVERY

FEBRUARY 24
2004

910,873 vehicles recalled

1999 PONTIAC BONNEVILLE -- 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.

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.

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.

NHTSA Campaign #99V089000 POWER TRAIN:AUTOMATIC TRANSMISSION

APRIL 26
1999

99,333 vehicles recalled

1999 PONTIAC BONNEVILLE -- 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.

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.

Dealers will replace the manual valve/link assembly with a replacement manual valve/link kit, featuring a spring-type fastener. For detailed information & supporting documents, see the official NHTSA page concerning recall #99V089000 »
