2001 Mitsubishi Diamante recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-19. Recalls apply to specific VINs — run your VIN to confirm.
2 safety recalls, most serious first
1. Equipment
What's wrong, in plain English: A part or accessory supplied with the vehicle. CERTAIN SPORT UTILITY AND PASSENGER VEHICLES FAIL TO COMPLY WITH FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 225, "CHILD RESTRAINT ANCHORAGE SYSTEMS." THE OWNER'S MANUAL DOES NOT CONTAIN A STEP-BY-STEP DESCRIPTION FOR HEADREST ADJUSTMENT WHEN INSTALLING A CHILD RESTRAINT SYSTEM (CRS) TETHER STRAP.
What could happen: IF THE TETHER STRAP IS IMPROPERLY INSTALLED TO THE TETHER ANCHOR, THE CHILD SAFETY SEAT MAY NOT BE SUFFICIENT RESTRAINED. IN THE EVENT OF A CRASH, THE CHILD COULD BE INJURED.
The fix: A LETTER OUTLINING THE PROBLEM WILL BE SENT TO OWNERS ALONG WITH A STICKER CONTAINING THE CORRECT INSTRUCTIONS AS WELL AS INSTRUCTIONS ON WHERE TO AFFIX THE STICKER IN THE OWNER'S MANUAL. THE RECALL BEGAN ON MARCH 29, 2004. OWNERS SHOULD CONTACT MITSUBISHI AT 1-888-648-7820.
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 2001 DIAMANTE.
- Book a repair at any authorized Mitsubishi dealer. Quote NHTSA campaign 04V067000.
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-888-648-7820.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.
