1993 Mitsubishi Diamante recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-20. Recalls apply to specific VINs — run your VIN to confirm.
3 safety recalls, most serious first
1. Seat belts
What's wrong, in plain English: Seat belts may not hold you in a crash. THE REAR OUTBOARD LOWER SAFETY BELT ATTACHMENT BOLT WAS INADEQUATELY TORQUED ON INSTALLATION.
What could happen: THE INADEQUATELY TORQUED ANCHOR BOLT COULD FAIL INA SUDDEN STOP OR ACCIDENT. FAILURE OF THE SAFETY BELT ASSEMBLY RESULTS ININCREASED RISK OF INJURY TO THE SEAT OCCUPANT.
The fix: RETORQUE THE SAFETY BELT ATTACHMENTS TO THE CORRECT SPECIFICATION.
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 1993 DIAMANTE.
- Book a repair at any authorized Mitsubishi dealer. Quote NHTSA campaign 93V044000.
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.
