2000 Buick Park Avenue recalls and complaints

Problem: 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.

Risk: 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.

Remedy: 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.

Problem: 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.

Risk: 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.

Remedy: Dealers will replace the windshield wiper motor cover which contains the microprocessor.

Problem: Vehicle description: passenger vehicles. Some of these vehicles have internal fluid leaks in the brake hydraulic control unit.

Risk: When the rear brake proportioning, antilock brake, traction control, or stability control feature is activated in some driving situations, the feature may not perform as designed.

Remedy: Dealers will inspect the abs hydraulic modulator unit and if necessary, replace the hydraulic modulator.
