OK, just so you won't feel all alone. But this won't answer your question. Honestly I have never experienced/noticed anything with respect to the quoted item above. How would I even know this was happening? I have close to 10K miles on the odometer. Once in a while it gets a bit noisy when I have come back home and parked it in the garage and turned off the engine.
