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.

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… Repairs typically run $200-$3,500. Severity: high.
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… Repairs typically run $300-$1,500. Severity: high.

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 r… Repairs typically run $1,500-$5,000. Severity: medium.
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 descri… Repairs typically run $100-$1,500. Severity: medium.
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 coo… Repairs typically run $200-$700. Severity: medium.
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-… Repairs typically run $150-$2,500. Severity: medium.
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… Repairs typically run $150-$500. Severity: medium.
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… Repairs typically run $50-$600. Severity: low.
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 a… Repairs typically run $50-$800. Severity: low.
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 common… Repairs typically run $200-$900. Severity: low.
