Any previous printed versions of this bulletin should be discarded. In the event that a Toyota vehicle becomes submerged in water, many components may be physically damaged. Electrical and electronic components, including wiring harnesses, are particularly susceptible to corrosion and subsequent malfunction. Although any flooding can be damaging, salt water flooding elevates the potential for abnormal conditions and may increase risks due to its highly corrosive and conductive nature. Salt residue also continues to corrode and remain conductive even after a vehicle dries.

The failure pattern owners describe
The 2006 RAV4's electrical and computer systems throw out false alarms and critical failures without clear causes. Owners describe repeated episodes where multiple warning lights (Check Engine, VSC, ABS, 4WD, airbag, power steering) illuminate at once, followed by loss of engine power, stalling, hard steering, and brake failure—all while the vehicle is being driven at highway speed. The vehicle typically resumes normal operation after the owner shuts it off and restarts, but the incidents recur frequently enough to be terrifying. Dealers and independent mechanics run diagnostics and find nothing, or they replace the ECM only to have the same fault code reappear minutes later.
Ignition coil failures are endemic; owners report all six coils failing by 66,000 miles despite being rated to last to 120,000 miles. Dealers acknowledge this as a known pattern in RAV4s (and similar Toyota models) but do not offer recalls or technical service bulletins.
Battery warning lights flicker during acceleration or the entire electrical system cuts out, yet battery and alternator testing passes. Wheel speed sensors fail sequentially and become back-ordered for weeks. The airbag clock spring (spiral cable assembly) fails at 60,000 miles—a costly $514 repair—and the dealer notes this happens "all the time."
One owner's warning lights never turned off after purchase, cycling through repairs to the gas cap, charcoal canister, gas tank, and gaskets with no resolution. Another experienced sudden full-throttle acceleration on startup after humid nights, clearing only after restart. A third lost all control of the transmission, power steering, and brakes when the onboard computer malfunctioned.

Failure modes owners describe
Electronic Control Module (ECM) / Computer Malfunction
The onboard computer fails or becomes unstable, triggering multiple warning lights (Check Engine, VSC, ABS, 4WD, airbag) and causing loss of engine power, transmission shifting problems, hard steering, brake failure, and safety system disablement. Owners report the vehicle can stall without warning or behave as if in neutral.
When: Varies from 37,000 to 119,000 miles; incidents occur repeatedly over months or persist from purchase
Symptoms owners cite: Multiple dashboard warning lights illuminate simultaneously (Check Engine, VSC, ABS, 4WD, airbag, power steering); Sudden deceleration or loss of power while driving; Vehicle stalls or appears to shift into neutral on highway; Hard steering and non-functional brakes; Transmission slipping or harsh shifts; Electrical components become inoperable; Lights reset after engine shutdown and restart
Codes mentioned: P0606
Repairs/costs cited: ECM replacement attempted under warranty but fault recurred 10 minutes later in one case. Software update performed in another case but failure recurred. Dealers unable to diagnose intermittent issues despite repeated attempts.
Recalls/TSBs owners mention: Covered under NHTSA campaigns 11V113000 (Vehicle Speed Control), 13V383000 (Suspension), 15V689000 (Visibility), 16V096000 (Seat Belts); parts not available for some recall repairs
Ignition Coil Failure
One or more ignition coils fail prematurely, causing cylinder misfires, hesitation, lack of power, and Check Engine light illumination. Multiple coils may fail simultaneously or sequentially. Owners note this as a known issue in online forums and report it occurs well before the recommended 120,000-mile spark plug change interval.
When: 66,000 miles reported in one case; coils expected to last to 120,000 miles
Symptoms owners cite: Check Engine light illuminates; Multiple cylinder misfire; Engine hesitation and loss of power; Lack of acceleration
Codes mentioned: P0352, Multiple cylinder misfire codes
Repairs/costs cited: All six ignition coils require replacement; costs estimated around $1,500 for diagnostics and repair. Spark plugs are secondary concern (scheduled replacement at 120K miles).
Recalls/TSBs owners mention: Dealers acknowledge this as a known issue but offer no recall or TSB information
Battery / Charging System Electrical Anomaly
Battery warning light flickers or illuminates intermittently, often when accelerating on the highway. The vehicle loses all electrical power, steering becomes hard, and brakes fail. Battery and alternator test good, and replacement of both components does not resolve the issue. Problem may be related to a deeper electrical bus or PCM issue rather than the battery or alternator themselves.
When: Occurring at highway speeds; one complaint mentions battery and alternator replaced two years prior without resolving recurring issue
Symptoms owners cite: Battery warning light flickers or comes on when accelerating; Loss of all electrical power while driving; Hard steering (loss of power steering); Non-functional brakes; All warning lights illuminate (Check Engine, TCS, VSC, 4WD, brake, airbag); Requires towing (happened twice in one case)
Repairs/costs cited: Battery and alternators tested good by multiple mechanics and AutoZone; both replaced two years prior without resolving recurrence. Three mechanics and AutoZone could not identify root cause.
Spiral Cable Assembly / Airbag System Failure
The spiral cable assembly (part of the airbag clock spring) fails, disabling all airbag functionality. The vehicle is unsafe to drive until repaired. Owners report the dealer states this is a common, recurring problem in RAV3s and Tundras as well, suggesting a design flaw rather than random failure.
When: 5 years old, 60,000 miles in one case
Symptoms owners cite: Airbag malfunction warning light on dashboard; Airbags completely non-functional until repair
Repairs/costs cited: Spiral cable assembly replacement cost: $514.00
Recalls/TSBs owners mention: Dealer states this is seen frequently in RAV3s and Tundras; no recall mentioned. Service manager had no information on whether this is a known recall issue.
Sudden Acceleration on Startup
After a humid night or following engine shutdown/restart, the engine races to full power without driver input on the accelerator pedal. Condition clears after turning off and restarting the engine. Owners consider this a serious safety hazard if the vehicle is in gear.
When: Happened 5 times in 60 days in one report
Symptoms owners cite: Engine revs to full power immediately upon startup; Occurs after humid nights or following recent engine shutdown/restart; Vehicle out of control if in gear; Clears after engine shutdown and restart
Recalls/TSBs owners mention: Owner contacted Toyota; not comfortable with manufacturer's response regarding safety concern
Wheel Speed Sensor Failure
Rear wheel speed sensors fail sequentially or independently. When both sensors fail (left rear sensor failed shortly after right rear sensor), the vehicle becomes dangerous to drive. Sensors are back-ordered, leaving owners without safe transportation.
When: Right rear wheel sensor failed on 1/19/11; left rear wheel sensor failed on 2/2/11 (14 days later); back-order window extended from 1/19/11 to 2/24/11
Symptoms owners cite: VSC or ABS warning light activation; Vehicle becomes dangerous to drive when both sensors fail
Repairs/costs cited: Sensors back-ordered for extended periods; dealer initially assured owner that single sensor failure was safe to drive, but subsequent failure proved otherwise.
Evaporative Emission Control System (EVAP) / Charcoal Canister False Warnings
Dashboard warning lights (VSC, 4WD, Check Engine) illuminate repeatedly despite multiple repairs. Initial diagnosis pointed to faulty gas cap, then charcoal cylinder, then gas tank, then gasket tightening—none resolved the issue. System generates false or persistent readings causing chronic light illumination.
When: Started on first day of ownership; persisted through multiple repair attempts
Symptoms owners cite: VSC, 4WD, and Check Engine lights illuminate repeatedly; Lights recur despite multiple repair attempts; False or persistent diagnostic readings; Transmission feels like it slips when accelerating from stop on a hill (reported in similar complaint)
Repairs/costs cited: Replaced: faulty gas cap, charcoal cylinder, gas tank, tightened gaskets. None resolved the recurring warning lights.
Power Window Master Switch Malfunction
The power window master switch operates intermittently—sometimes working, sometimes not. Switch may overheat. Issue prevents reliable window operation.
When: Timing not specified
Symptoms owners cite: Power window switch works intermittently; Switch overheat reported
Digital Radio Display and Control Failure
The digital radio display becomes blank or illegible, and controls become inactive except for steering wheel mode and volume buttons. Problem resolves when the vehicle is shut off and restarted, indicating a temporary electrical glitch in the head unit.
When: Occasional occurrence
Symptoms owners cite: Digital radio display goes blank or becomes illegible; Radio controls become inactive; Only steering wheel mode and volume buttons function; Problem corrects itself after shutdown and restart
No-Start Condition with Good Battery
Vehicle fails to start on first attempt, especially in morning or after work. Dashboard lights illuminate, battery condition indicator shows good, and battery tests good. Starter shows no signs of sluggishness or low power. Issue resolves on its own when retried. Intermittent nature makes dealer diagnosis difficult.
When: First thing in morning or sometimes after work
Symptoms owners cite: Vehicle fails to start; Dashboard lights come on; Battery condition indicator checks good; Vehicle eventually starts on retry
Repairs/costs cited: Battery tested and confirmed good; no starter issues detected
Transmission Behavior Anomaly (Neutral Shift)
While driving on the highway, vehicle behaves as if it has shifted into neutral. Engine revs when accelerator is applied, but vehicle does not accelerate. Issue resolves after pulling over, placing vehicle in park, then back in drive.
When: At 65 mph on highway
Symptoms owners cite: Vehicle behaves as if in neutral while driving; Engine revs without vehicle accelerating; Problem clears after downshift to park and back to drive
