| Description of the problem | Our 2004 toyota sienna developed a clicking or popping sound in the steering column when turning left or right after about 3 seasons of winter driving in minnesota. The dealer said that they did not hear/feel the problem. Each consecutive winter the symptoms would get worse and the toyota dealer claimed they could not duplicate the noise or hear a problem. About 4 months ago, the steering became erratic and felt un-boosted at times requiring a great deal of effort to turn the wheel. I did some research online and came across a toyota technical service bulletin st003-04 where they describe a shaft noise that is caused by corrosion. The nhtsa investigation concluded that toyota's claims that the noise was minor, not a safety hazard, and occurred infrequently. We took the sienna back to the dealer and i specifically asked them to examine the intermediate shaft and showed them the tsb. They reported back that i had a severely corroded intermediate shaft from road salt and it had seized at one end of the connection. The tsb campaign was only good for the first 36,000 miles (our van had about 82,000 miles at the time of the repair) so the out of cost expense to make the vehicle safe to steer again was $527. I can not speak to the frequency this defect affects other 2004 siennas, but i can attest to a number of near misses on the road caused by the erratic and lack of power steering assist caused until the repair was finally diagnosed and fixed. Corrosion resistance of steering components should be a fundamental attribute of any vehicle as the loss or diminished capacity of that function instantly creates a hazard to the vehicle occupants and others on the road. |
