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 1998 OLDSMOBILE Achieva. Campaign records are official safety actions; applicability to a particular car still requires its VIN.

ON CERTAIN PASSENGER VEHICLES. IF THE ENGINE FAILS TO START AND THE DRIVER HOLDS THE KEY IN THE "START" POSITION FOR AN EXTENDED PERIOD, HIGH CURRENT FLOWS THROUGH THE IGNITION SWITCH, AND SOMETIMES PRODUCES ENOUGH HEAT TO MELT INTERNAL SWITCH PARTS.
Consequence
IF THE SWITCH IS DAMAGED, A FIRE COULD OCCUR IN THE STEERING COLUMN, EVEN WITH THE ENGINE OFF AND THE KEY REMOVED. THE FIRE COULD SPREAD TO THE INTERIOR OF THE CAR, WHICH COULD INJURE OCCUPANTS OR CAUSE DAMAGE TO ADJOINING STRUCTURES.
Remedy
DEALERS WILL INSTALL A RELAY KIT IN THESE VEHICLES TO PREVENT HIGH CURRENT FROM FLOWING THROUGH THE IGNITION SWITCH, AND CHECK THAT YOUR CAR WILL START WITH A PROPERLY CHARGED BATTERY AND, IF NECESSARY, REPLACE THE IGNITION SWITCH. OWNER NOTIFICATION WILL BEGIN ON MARCH 1, 2004. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT CHEVROLET AT 1-800-630-2438, PONTIAC AT 1-800-620-7668, BUICK AT 1-866-608-8080, OR OLDSMOBILE AT 1-800-630-6537.

Complaints across nearby Oldsmobile Achieva 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.
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.
