1992 Mitsubishi Diamante common problems

The most-reported problem areas across all 49 owner complaints filed with NHTSA — and what to check before you buy.

Engine And Engine Cooling
Check coolant level and color, look for leaks, and confirm the engine reaches normal temperature without overheating.
Electrical System
Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
Service Brakes
Brakes should feel firm and quiet — no grinding, pulsing or pulling. Check for an ABS light and uneven pad/rotor wear.
Hydraulic
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
Air Bags
Confirm the airbag light turns on then off at startup — if it stays lit there's a fault (costly, and a safety risk). Check for signs of prior deployment.
Suspension
Listen for clunks over bumps, check the car sits level, and look for uneven tire wear and worn shocks or struts.

About the Mitsubishi Diamante

The Mitsubishi Diamante is an automobile that was manufactured by Mitsubishi Motors from 1990 to 2005. The first series was a hardtop introduced to the public at the Tokyo Motor Show in 1989. It went on sale in Japan exclusively in May 1990 and won that year's Japan Car of the Year award. It was created by splicing an extra 6.6 cm (2.6 in) right down the middle of the Mitsubishi Galant, which itself had won the Japan Car of the Year award in 1987. The Diamante's platform was also used for the sporty Mitsubishi 3000GT.
