Yes, the mechanic was aware of the TSB, but said that it was being implemented slowly or regionally to ensure it was a true fix. I believe it had to do with installing a cycling switch.

But when he mentioned that it would be somewhat involved and require drilling and such, I chose to try the workaround. If running the rear air on long trips "fixes" the problem, then I'm cool with that

Hope all is well with you. Thanks for the reply.
