| Description of the problem | Airbags intermittently and unpredictably become non-functional. That is, the warning light goes on and off at unpredictable intervals. I am told by the dealer service representatives that the airbags are non-functional (i. E., system shut down) when the warning light is flashing. This is a severe safety concern to me for the sake of my family. It is galling since the airbag system was a major selling point of the car. Attempted repairs by dealer on august 4, 2009 under warranty replaced the airbag assembly on one side but did not fix the problem of repeated intermittent failure. After the vehicle was out of warranty, toyota refused to address their failed attempts at repair, and i was quoted well over $2,000 to fix the problem as per toyota service bulletin t-sb-1062-10 on july 20, 2011. This proposed repair apparently included replacing the previously replaced airbag as well as the assembly on the other side. I delayed the repair at risk to family on account of the extreme cost. Also, i appealed to toyota corporate representatives since the problem had been a persistent and unremedied one since during the warranty period. Recently, the toyota dealer informed me that a new toyota service bulletin isolates the defect somewhat from previous toyota t-sb-1062-10 and reduces the cost of the repair to somewhere near $400 (although i paid $47. 50 to learn that). But after that recent service by toyota on june 20, 2013, the warning light is off again, and the airbags are presumably functioning again for a while. This intermittently has been the problem with getting this defective airbag system fixed under warranty as it should be. Also, the intermittent and repeated failure of the units suggests a faulty design and a safety defect that should be addressed in all of the vehicles. I have seen similar airbag concerns of other 2006 sienna owners on various online bulletin boards. |
