What is the 1991-1996 Mitsubishi 3000GT VR-4 4WS Rear Steering Pump and Hard Line Leaks?

The all-wheel-steering (4WS) system on the 1991-1996 VR-4 (and select 1991-1993 SL trims) uses a dedicated rear-mounted hydraulic pump driven off the rear-differential pinion. The pump's flanged metal feed line is mounted under the car and rusts heavily over time. When the line c… Repairs typically run $150-$2,000. Severity: high.

What is the 1991-1993 Mitsubishi 3000GT ECU Electrolytic Capacitor Leakage Causing Stalling and No-Start (1991-1993)?

The electrolytic capacitors inside 1991-1993 ECUs leak corrosive electrolyte with age and heat cycling, eating copper traces off the circuit board. The result is erratic running, stalling, intermittent or complete no-start, and — if left long enough — an unrepairable ECU. The 300… Repairs typically run $100-$600. Severity: high.

What is the 1991-1999 Mitsubishi 3000GT Getrag AWD Manual Transmission Synchro Wear and Gear Grind (VR-4 5-Speed/6-Speed)?

The Getrag-built AWD gearboxes in the VR-4 (W5MG1 5-speed through 1993, W6MG1 6-speed from 1994) are notorious for worn synchronizers, especially 1st-2nd and 2nd-3rd, causing grinding shifts. The synchros are undersized for the mass of the gears at high engine speed, so spirited… Repairs typically run $2,000-$4,500. Severity: high.

What is the 1991-1993 Mitsubishi 3000GT AWD Transfer Case Oil Leak Leading to Bearing Failure and Driveline Lockup (VR-4)?

The all-wheel-drive transfer case on early 3000GT VR-4 models can leak gear oil past its seals and O-rings, and because the unit holds very little fluid, even a slow leak starves the bearings. NHTSA issued two recalls for this defect (93V-033 and 02V-143) because bearing failure… Repairs typically run $300-$2,500. Severity: high.

What is the 1991-1994 Mitsubishi 3000GT Front Brake Hose Cracking at Full Steering Lock (NHTSA Recall 96V-143)?

On 1991-1994 cars, the front wheel-side brake hoses can crack when the steering is at full lock with the suspension at full travel, leaking brake fluid. NHTSA recall 96V143 covered roughly 10,000 vehicles built between August 1990 and November 1993 because the resulting fluid los… Repairs typically run $150-$450. Severity: high.

What is the 1991-1999 Mitsubishi 3000GT Timing Belt and Hydraulic Tensioner Failure Destroying the Interference DOHC 6G72?

The DOHC 24-valve 6G72 in the SL and VR-4 is an interference engine: if the timing belt snaps or the known-weak hydraulic tensioner bleeds down and lets the belt skip teeth, pistons strike open valves. Documented failures have bent as many as 17 of the engine's 24 valves, turning… Repairs typically run $700-$4,500. Severity: high.

What is the 1991-1993 Mitsubishi 3000GT Pop-Up Headlight Motor and ETACS Failures (1991-1993)?

Pre-facelift cars use motorized pop-up headlights controlled by the ETACS body module, and after 30+ years the motors, internal position switches, fuses, and ETACS relays commonly fail. Lights stick up, stick down, raise slowly, or only one side operates (the classic 'wink'). Bec… Repairs typically run $100-$600. Severity: medium.

What is the 1991-1999 Mitsubishi 3000GT Hydraulic Lash Adjuster 'Lifter Tick' on the 6G72 V6?

The 6G72's hydraulic lash adjusters are prone to internal varnish buildup and wear, producing the platform's famous ticking noise at idle that rises with RPM. Dirty oil or extended change intervals make the adjusters bleed down and stick, increasing valvetrain clearance. It is mo… Repairs typically run $50-$1,500. Severity: low.

What is the 1991-1994 Mitsubishi 3000GT Active Exhaust Valve Seizure and Cable Rot (VR-4)?

Early VR-4s have an Active Exhaust System with a driver-selectable Tour/Sport valve in the rear exhaust; the system was phased out after the 1994 model year. The valve shaft corrodes and seizes (usually stuck in the quiet Tour position) and the actuator cable rots away, so toggli… Repairs typically run $50-$450. Severity: low.
