1995 Toyota Supra Problems: 9 Known Issues

On the 1993-1996 Toyota Supra, 1993.5-1996 Supras use a complex braking setup with a separate ABS actuator plus a TRAC (traction control) pump, nitrogen accumulator, and TRAC actuator. These hydraulic units are a notorious failure point on aging cars, causing a constantly running or noisy pump, illuminated ABS/TRAC lights, and a soft or spongy brake pedal that survives repeated bleeding. The system also traps air against its solenoid valves, making brakes hard to bleed correctly without the factory key-on self-test procedure; 1997+ cars received a smaller, simpler ABS unit without the TRAC pump.

On the 1993-1998 Toyota Supra, the 2JZ-GTE's factory sequential twin-turbo system relies on a network of vacuum switching valves (VSVs), pressure tank, and actuators (EGCV, IACV, exhaust gas bypass) to bring the second CT12B turbo online around 4,000 RPM. With age, VSVs fail, vacuum lines crack, and actuators stick, causing low boost, a missing or violent 4,000 RPM transition, or a second turbo that never spools. The #1 (primary) turbo also runs the hardest and its exhaust-side seals commonly wear, producing blue/white smoke on deceleration after boost and oil in the downpipe.

On the 1993-1998 Toyota Supra, turbo models with the Getrag V160 6-speed commonly develop worn synchronizer rings, with 3rd gear typically the first to grind during fast or cold shifts. The gearbox itself is extremely strong, but a worn or dragging clutch accelerates synchro wear, and V160 internal parts are rare and expensive, making neglected synchro wear a costly repair. The issue is well documented across SupraForums and UK MKIV owners' club threads.

On the 1993-1998 Toyota Supra, automatic MKIVs use the Aisin A340E, whose relatively small lockup clutch is prone to shudder during partial and full lockup engagement, typically felt as a vibration at light-throttle cruise. The most common causes on these cars are aged or incorrect fluid — the TT A340E's flex-lockup control requires Toyota Type T-IV ATF, and generic Dexron causes shift flare and lockup shudder — along with worn accumulators and dirty solenoid/connector contacts; sustained slipping eventually glazes the converter clutch.

On the 1993-1998 Toyota Supra, the original radiator uses crimped plastic end tanks on an aluminum core, and after two-plus decades the plastic becomes brittle and develops hairline cracks, typically along the upper tank. Cracks often only open under pressure when the engine is hot, so the leak shows up as coolant smell, sticky residue, or slow coolant loss rather than an obvious drip. Owners note the black plastic tanks turning greenish/brown as a warning sign of impending failure.

On the 1993-1998 Toyota Supra, aging heater cores and their o-ring pipe connections leak coolant into the cabin, producing a sweet coolant smell, fogged windshield, and damp passenger-side carpet. The part itself is cheap, but on the MKIV the heater core sits behind the full dashboard, and owners widely describe dash removal as one of the worst jobs on the car, taking a full weekend for a DIYer.

On the 1993-1998 Toyota Supra, the rubber rear subframe mounts and differential bushings deteriorate with age and torque load, producing a clunk or bang from the rear when getting on or off the throttle, wheel hop under hard launches, and a vague, swaying rear end on the highway. This is one of the most commonly diagnosed rear-end noises on MKIVs, with multiple dedicated DIY threads on SupraForums.

On the 1993-1998 Toyota Supra, sport Roof (targa) cars commonly leak water down the A-pillars and along the tops of the door glass, and develop an annoying chatter/rattle from the roof panel over bumps. Causes are aged/compressed targa weatherstrips, clogged or dirty drip rails, loosened targa latch bolts, and door glass that has developed play and no longer presses firmly against the seals. This is listed in virtually every MKIV buyer's guide as a standard checklist item.

On the 1993-1998 Toyota Supra, after 25-plus years, MKIV interior plastics — door panel tops, trim clips, plastic gaskets, and the foam backing behind the vinyl door panels — become brittle and crack or tear, often breaking during routine disassembly for stereo, window, or heater work. Replacement OEM panels are expensive and increasingly hard to find, so cracked and sagging interior trim is now a near-universal condition item on these cars. Worn coil pack, injector, and cam sensor connector clips snapping is a related, frequently cited age problem.
