What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2004 DIAMANTE.
- Book a repair at any authorized Mitsubishi dealer. Quote NHTSA campaign 04V428000.
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-787-251-8715.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.
