Owners of 2006 4Runners describe airbags that failed to deploy in frontal collisions at moderate speeds (35-50 mph) where impact severity caused $9,300-$11,000 in frame damage and occupant injuries including head trauma and burns. After-accident EDR inspections conducted by Toyota concluded insufficient deceleration or oblique impact angles explained non-deployment, though owners dispute these findings.
Several owners report the airbag warning lamp illuminating during normal driving, traced to failures in the steering column spiral cable assembly. One owner's dealer initially dismissed it as a lamp-only issue; later diagnosis confirmed electrical damage to the spiral cable that can deactivate the driver airbag. Recalls addressing this issue (NHTSA Campaigns 15V285000 and 16V065000) have been issued, though some owners report their model year was not included despite identical failure modes.
One owner experienced erroneous side-impact airbag deployment at 5 mph while exiting a driveway with no collision or rollover. Toyota's response attributed this to rollover, which the owner disputes.
Takata airbag recall parts have remained unavailable for extended periods—owners received recall notices in 2016 with no parts available and no repair timeline. This left vehicles unrepaired and owners unable to address official safety recalls. Dealer responsiveness to recall appointments has also been inconsistent.
Failure modes owners describe
Non-deployment in frontal collision
Airbags did not deploy during frontal or angled frontal crashes at moderate speeds (35-50 mph), despite sufficient impact severity to cause major frame damage and passenger injury.
When: Multiple incidents reported between 2013 and unspecified dates; one at 7,000 miles, one at 35 mph collision
Symptoms owners cite: Airbags failed to deploy during frontal impact; Vehicle damage extensive (front-end crushed, $9,300-$11,000 repair estimates); Occupant injuries (head trauma, burns)
Repairs/costs cited: EDR (Event Data Recorder) reports generated after accidents; one owner reported vehicle was repaired before inspection could be completed, preventing definitive root-cause determination
Recalls/TSBs owners mention: Toyota issued EDR reports attributing non-deployment to insufficient forward deceleration or oblique impact angle rather than airbag system failure; no recall issued for non-deployment failures
Spiral cable assembly electrical failure
The steering column spiral cable assembly develops electrical damage when the steering wheel is turned, causing the airbag warning lamp to illuminate and potentially deactivating the driver airbag.
When: Reported at 87,000 miles, 145,000 miles, 153,953 miles; timing unclear for others
Symptoms owners cite: Airbag warning lamp illumination while driving; Warning light reappears after clearing; Driver airbag may be deactivated
Repairs/costs cited: Replacement of spiral cable assembly required; one owner cited Toyota recall documentation describing this failure mode
Recalls/TSBs owners mention: Recalls issued (owners cited NHTSA Campaign 15V285000, 16V065000) but initial dealers downplayed problem; some owners' vehicle model years were not included in recall scope despite having identical failure
Erroneous side-impact deployment
Side-impact airbags deployed without any collision or crash event at very low vehicle speed during normal driveway exit, posing unintended injury risk.
When: At 133,000 miles
Symptoms owners cite: Side airbags deployed without warning at 5 mph; No collision or rollover event occurred; Owner felt unsafe driving vehicle after incident
Repairs/costs cited: No repair performed
Recalls/TSBs owners mention: Toyota sent representative who attributed deployment to vehicle rollover despite owner's clear assertion that no crash or rollover occurred; no further assistance provided
Takata recall parts unavailability
Owners received official recall notices for Takata airbag issues but dealers could not perform repairs because recall remedy parts remained on back order for extended periods, leaving vehicles unrepaired and owners unable to comply with safety recalls.
When: Recall notices issued in 2016; parts unavailable as of complaint filing dates in 2016 and beyond
Symptoms owners cite: Airbag warning lamp present; Recall notice received but no repair timeline available; Parts on indefinite back order
Repairs/costs cited: No repair completed; technicians informed parts were on back order with no estimated arrival
Recalls/TSBs owners mention: NHTSA Campaigns 15V285000 and 16V065000 issued; parts distribution problems prevented recall completion at dealerships
Airbag warning lamp without clear cause
Airbag warning lamp illuminates during normal driving with no immediate failure, leaving owners uncertain whether airbags are functional and unable to obtain clear diagnosis or timeline for repair.
When: Reported at various mileages including mid-life service intervals; one owner reported light appearing and disappearing after 200+ miles
Symptoms owners cite: Airbag warning lamp illuminates; Lamp persists or reappears; Owners uncertain if airbag system is operational; Recall status confusing to owners
Repairs/costs cited: Initial dealer evaluation sometimes dismissed as minor lamp issue; later diagnosis revealed spiral cable failure or Takata recall applicability
Recalls/TSBs owners mention: Takata recall notices and spiral cable assembly recalls issued but owners report confusion over which recall applies and parts availability
