AIR BAGS:FRONTAL:DRIVER SIDE:INFLATOR MODULE

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 1998-2000 RAV4, 1998-1999 RAV4 EV and Celica and 1997-1998 Supra vehicles. These vehicles were equipped with Non-Azide Driver air bag Inflators (NADI) and do not contain phase stabilized ammonium nitrate (PSAN) propellant. Due to a manufacturing issue, the NADI inflators may absorb moisture, causing the inflators to rupture or the air bag cushion to underinflate.

    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.

    Common Symptoms

    • Low or no boost from the first turbo below 4,000 RPM
    • Second turbo never comes online; boost falls flat above 4,000 RPM
    • Harsh, delayed, or missing sequential transition around 4,000 RPM
    • Blue/white smoke on deceleration after boosting (worn turbo seals)
    • Black smoke and sluggish response when trying to build boost

    How to Fix

    Pressure-test the sequential system and vacuum-test each VSV and actuator per the wilbo666/TSRM diagnostic procedure; replace failed VSVs, the pressure tank check valve, and hardened vacuum hoses. If the primary turbo smokes or shows shaft play, rebuild or replace the CT12B turbos. Many owners convert to true twin (parallel) mode or a single turbo, but a stock-correct repair is replacing the failed VSVs/actuators and worn turbo.

    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.

    Common Symptoms

    • Soft or spongy brake pedal that bleeding does not fix
    • ABS and/or TRAC warning lights on
    • TRAC/ABS pump running constantly or making loud groaning noises
    • Reduced ABS function or inconsistent pedal feel

    How to Fix

    Diagnose stored ABS/TRAC codes and pump operation; depressurize the nitrogen accumulator before bleeding and use the ignition-on self-test bleeding procedure to purge trapped air. Replace the failed ABS actuator, TRAC pump, or accumulator with good used or rebuilt units. Many owners perform the documented TRAC pump/actuator removal with re-routed brake lines, which keeps ABS functional, but a stock repair preserves traction control.

    Typical repair cost:$300 - $1,500

    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.

    Common Symptoms

    • Grinding or crunching when shifting into 3rd gear, especially when cold or shifting quickly
    • Notchy engagement that improves when shifting slowly
    • Grind spreading to other gears as wear progresses

    How to Fix

    Address clutch drag promptly and use the correct gear oil to slow wear. Once grinding starts, the fix is a transmission rebuild with new or upgraded (carbon-lined) synchro rings from a V160 specialist such as Jack's Transmissions; budget accordingly since V160 parts availability is limited.

    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.

    This issue also affects: Lexus RX

    Common Symptoms

    • Vibration or shudder at light throttle around 40-50 mph as the converter locks
    • Shift flare or harsh lockup engagement
    • Slipping under boost or heavy throttle on TT autos
    • Worsening symptoms with old or incorrect ATF

    How to Fix

    Service the transmission with the correct Toyota Type T-IV fluid and a new filter, and clean/check the transmission connectors and speed sensors. If shudder persists after a proper fluid service, the torque converter clutch is worn and the converter should be replaced (or upgraded) during a rebuild; shift kits/shimming reduce slipping on higher-power cars.

    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.

    Common Symptoms

    • Sweet coolant smell inside the cabin
    • Windshield fogging with an oily film, especially with the heater on
    • Damp passenger-side carpet
    • Unexplained coolant loss

    How to Fix

    Pressure-test the cooling system and inspect the passenger footwell to confirm the heater core (versus a heater hose) is leaking. Replace the core and the o-rings at the inlet/outlet pipes while the dash is out — some owners solder the pipe joints for a permanent seal — and replace the aged heater valve and hoses at the same time to avoid repeating the labor.

    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.

    Common Symptoms

    • Slow coolant loss with no visible puddle
    • Coolant smell or dried pink/green residue on top of the radiator
    • Hairline crack along the plastic upper tank visible when hot/pressurized
    • Overheating in traffic if the leak progresses

    How to Fix

    Replace the radiator rather than attempting epoxy repairs. Options are a new OEM-style radiator or an all-aluminum replacement such as a Koyo, which eliminates the plastic end tanks entirely; replace the cap and inspect aged hoses at the same time.

    On the 1993-1998 Toyota Supra, the original in-tank Denso fuel pump wears with age and mileage — brushes, commutator, and pump vanes degrade — so output drops below the pump's original rating. Flow testing documented on MKIV.com showed measurably reduced output from older stock pumps, and on turbo cars a tired pump can cause lean conditions under boost, especially with a low fuel level, which risks engine damage. NA cars see hard starting and high-RPM misfire/surging instead.

    This issue also affects: Lexus NX

    Common Symptoms

    • Lean air/fuel ratio under boost, worsening below half a tank
    • High-RPM surging, misfire, or loss of power under load
    • Long cranking before start
    • Whining fuel pump noise from the tank

    How to Fix

    Replace an original-era pump proactively with a new genuine Denso drop-in unit (the stock TT pump or the higher-flow 280 lph Denso variant); verify good voltage supply to the pump and replace the in-tank filter sock. Avoid running a tired pump hard on low fuel, and confirm air/fuel ratio under boost after replacement on turbo cars.

    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.

    Common Symptoms

    • Water dripping at the A-pillar or top corners of the windows in rain or car washes
    • Damp headliner, carpet, or musty smell after rain
    • Squeak or rattle from the roof panel over bumps
    • Wind noise around the targa seals at highway speed

    How to Fix

    Replace the targa and door weatherstrips, remove and clean the drip rails so water drains properly, and tighten the targa rear connection bolts per the well-known MKIV.com targa rattle fix (some owners add thread locker). Adjust the door glass via the regulator stop nuts so the window seats firmly against the roof seals.

    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.

    Common Symptoms

    • Cracked or warped door panel tops and trim pieces
    • Trim clips and plastic tabs snapping during removal
    • Sagging or dented vinyl panels with crumbling foam backing
    • Brittle electrical connector clips breaking under the hood and in the cabin

    How to Fix

    Warm plastics before removal and use proper trim tools to minimize breakage; replace broken clips with new OEM or aftermarket clip kits. Damaged door panels can be professionally refinished or re-wrapped, and good used or NOS panels sourced from the owner community; handle brittle connectors carefully and replace cracked pigtails.

    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.

    Common Symptoms

    • Clunk or bang from the rear under acceleration or lift-off
    • Wheel hop under hard acceleration
    • Rear end feeling loose or swaying at highway speed
    • Driveline vibration

    How to Fix

    Inspect the subframe mounts and diff bushings for cracking, separation, or excessive movement. The subframe mounts can be replaced without dropping the subframe, while the differential must come out to replace its bushings; OEM rubber, polyurethane (SuperPro), or solid bushings are available depending on noise/vibration tolerance.
