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 2001 KIA Optima. Campaign records are official safety actions; applicability to a particular car still requires its VIN.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE SIDE AIR BAG WIRE HARNESS FOR THE DRIVER POSITION COULD BE MIS-ROUTED, WHICH COULD RESULT IN IT BEING PINCHED OR CUT BY THE SEAT CUSHION TILT MECHANISM.
Consequence
DAMAGE TO THE WIRE HARNESS COULD RESULT IN THE SIDE AIR BAG NOT DEPLOYING IN AN ACCIDENT.
Remedy
DEALERS WILL CHECK FOR PROPER ROUTING OF THE SIDE AIR BAG WIRE HARNESS AND SECURE IT IN PLACE WITH A PLASTIC TIE-WRAP. IF THE WIRE HARNESS IS DAMAGED, IT WILL BE REPLACED. OWNER NOTIFICATION IS EXPECTED TO BEGIN DURING MAY 2001. 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 KIA AT 1-800-333-4542.
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH 2.5 AND 2.7 LITER V6 ENGINES, THE CRANKSHAFT POSITION SENSOR (CKP) CASES DID NOT MEET DIMENSIONAL SPECIFICATIONS.
Consequence
INTERNAL GAPS WITHIN THE CASES ALLOWED EPOXY TO CONTACT THE PRINTED CIRCUIT BOARD, WHICH RESULTED IN CRACKING OF THE CIRCUIT BOARD CAPACITOR. A DAMAGED CKP CAPACITOR COULD RESULT IN ENGINE STALLING.
Remedy
DEALERS WILL REPLACE THE CKP. OWNER NOTIFICATION BEGAN MARCH 28, 2003. 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 KIA AT 1-800-333-4542.

Complaints across nearby Kia Optima 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.
