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 1991 BUICK Regal. Campaign records are official safety actions; applicability to a particular car still requires its VIN.
CERTAIN REPLACEMENT FUEL FILTERS, FRAM BRAND NAME P/N G3727, WITH DATE CODES X52911 THROUGH X60801 SEQUENTIALLY OR X600141 AND A MEXICO COUNTRY OR ORIGIN MARKING ON THE FUEL FILTER HOUSING MANUFACTURED FROM OCTOBER 18, 2005, THROUGH MARCH 21, 2006, SOLD FOR USE ON THE VEHICLES LISTED ABOVE AND ON CERTAIN SCHOOL BUSES. (TO SEE THE SCHOOL BUS ENGINE SIZES, CLICK ON "DOCUMENT SEARCH" AND THEN "BUS APPLICATIONS"). THE CONNECTOR ON THE FUEL FILTER WAS NOT MANUFACTURED TO HONEYWELL'S SPECIFICATION. AS A RESULT, THE O-RING MAY NOT SEAT CORRECTLY ON THE FUEL LINE.
Consequence
THIS CONDITION MAY CAUSE AN INADEQUATE SEAL AT THE CONNECTION, POTENTIALLY LEADING TO A FUEL LEAK. IN THE PRESENCE OF AN IGNITION SOURCE, A FIRE COULD OCCUR.
Remedy
HONEYWELL WILL NOTIFY OWNERS AND REPLACE THE FUEL FILTERS FREE OF CHARGE. THE RECALL BEGAN ON OCTOBER 18, 2006. OWNERS MAY CONTACT FRAM CUSTOMER SERVICE AT 1-800-890-2075 (OPTION 1).
VEHICLE DESCRIPTION: PASSENGER VEHICLES ORIGINALLY SOLD OR CURRENTLY REGISTERED IN THE STATES OF CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MAINE, MARYLAND, MASSACHUSETTS, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WEST VIRGINIA, WISCONSIN, AND THE DISTRICT OF COLUMBIA, WHERE ROAD SALT USE IS HEAVY. A CONDITION WHERE ONE OR BOTH FRONT ENGINE CRADLE BOLTS CAN PULL THROUGH THE RETAINERS DUE TO CORROSION OF THE RETAINERS.
Consequence
IF BOTH BOLTS PULL THROUGH, THE FRONT OF THE CRADLE WOULD NO LONGER BE SUPPORTED AT THE MOUNTING LOCATIONS AND THE STEERING INTERMEDIATE SHAFT COULD SEPARATE FROM THE STEERING GEAR.
Remedy
DEALERS WILL REPLACE THE FRONT AND REAR FRAME/CRADLE BOLTS AND RETAINERS.
INCORRECT CLEAR FRONT SIDE MARKER BULBS WERE INSTALLED RATHER THAN AMBER BULBS. THIS DOES NOT CONFORM TO THE REQUIREMENTS OF FMVSS NO. 108, "LAMPS, REFLECTIVE DEVICES, AND ASSOCIATED EQUIPMENT."
Consequence
CONSEQUENCE OF NON-COMPLIANCE: DURING ILLUMINATION, THE BULBS WILL SHOW CLEAR RATHER THAN AMBER AND COULD MOMENTARILY CONFUSE OTHER DRIVERS.
Remedy
DEALERS WILL REPLACE THE CLEAR BULBS WITH THE CORRECT AMBER BULBS.

Complaints across nearby Buick Regal 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.

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.

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.
