About 2 months ago, the power steering assist stopped working and has been intermittent since. As I drove it to the dealership, I splashed into a puddle and the power steering returned. The dealership ran a check and found the code C2128 but said they could not replicate the problem. They found the PSA module cover was rusty. They wanted to charge $3,500 to replace the module as well as $2,300 to repair both front struts. I took my truck back (power steering inoperable) and researched parts, repair shops and recalls. There is a recall for PSA failure of the year of my vehicle though my truck is not included. I seem to have all the same issues as reported in the NHTSA recall. The power steering is presently still intermittent (wet weather seems to effect it) and feels generally unsafe as it fails and returns without warning. No other symptoms or indications before, during or after failure(s).
