Exact make, model and year evidence from official US sources. Recall campaigns, ODI investigations, complaint allegations and EPA estimates remain separate.
A campaign may cover only certain production dates, plants or equipment. A zero result here is not safety clearance. Use NHTSA’s official VIN tool for the individual vehicle.
Exact model-level NHTSA results for 2000 PONTIAC Bonneville. Campaign records are official safety actions; applicability to a particular car still requires its VIN.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. SOME OF THESE VEHICLES HAVE INTERNAL FLUID LEAKS IN THE BRAKE HYDRAULIC CONTROL UNIT.
Consequence
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.
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.
Consequence
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.

Complaints across nearby Pontiac Bonneville model years
Totals for the same nameplate, scaled against its highest year here. They are not adjusted for how many were sold, how old they are, how far they are driven, or how much publicity a fault received — an older or better-selling year will usually carry more reports. This shows where the reporting sits, not which year is better.
An investigation means ODI reviewed a possible safety issue for this exact model-year identity. Opening one is not a defect finding; closing one does not by itself clear a vehicle.

Identity, freshness and provenance.
The canonical URL is this file’s permanent public identifier. Source IDs and timestamps show exactly what was matched and when; they do not turn the evidence into a verdict.
Only NHTSA vPIC, NHTSA ODI complaints and investigations, NHTSA recalls and FuelEconomy.gov contribute to this vehicle claim. CPSC equipment notices are searched separately and never joined to vehicle fitment. UK MOT, Canadian, New Zealand and European records are not merged into this US claim.
06 · Research paths
Diagnose first. Confirm fitment.
These are transparent searches, not diagnoses or endorsed parts. Recall remedies come before purchases; exact part fitment requires VIN, trim, powertrain, production date and OE number.

Awin US and R2 affiliate inventory are not published until a US programme, merchant and exact-fitment projection are approved. No offer currently has both merchant approval and exact vehicle fitment, so commercial links never count as evidence.
