Complaint history

When NHTSA received these reports. Changes in reporting alone do not establish a change in failure rates.

Problems owners report

Listed groups have at least 3 complaints. The page includes the 20 largest groups plus any additional flagged groups; some complaints are not assigned to a group.

AI groups complaints by meaning; the groups are approximate. Share ratio compares the problem’s share of this vehicle’s complaints with its share on other vehicles over the last 24 months (shown from 3 recent complaints). A 2× ratio means twice the complaint share, not twice the failure risk. Flags mark unusual shares or recent surges after an AI review of the complaint content. “First signal” does not mean the pattern has persisted continuously.How recall estimates are calculated.

Recalls

• NHTSA recall #04V090000February 24, 2004910,873 vehicles affected

  fuel system, gasoline: delivery

  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.

  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.

  power train: automatic transmission

  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.

  Remedy

  Dealers will replace the manual valve/link assembly with a replacement manual valve/link kit, featuring a spring-type fastener.
