Two problems related to front air bag sensor control have been reported for the 2004 Toyota 4Runner. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2004 Toyota 4Runner based on all problems reported for the 2004 4Runner.
Vehicle has abnormal amount of rust on frame metal parts with excessive chipping an corrosion. Also, of almost more concern is that the airbag sensors are completely rotted through, as if they were sacrificial anodes. Frame failure due to abnormal rust could cause a catastrophic accident. Sensor failure of the airbag sensors (behind front bumper) while driving could cause serious injury or death to driver or other cars on the road. I have never seen anything like this amount of corrosion.
Malfunction in the center airbag sensor assembly in my vehicle has rendered the airbags inoperable. Sensor light came on two weeks ago. Toyota service garage said it would cost $545 to repair. No repair to date. Toyota indicated that it was only covered by 3-year warranty.
