The TSB states that this issue occurs after the engine has been off for at least 2 hours, and it usually lasts for 10 seconds, but may last longer in a few cases.
It outlines a very specific circumstance, and it needs to be consistent...otherwise is could be something else. I'm not saying it is....
One thing to check would be the oil level, that's mentioned in the TSB as a possible cause. Make sure the oil is of good quality and no more than one quart low.
The bulliten is very clear...so I'm not sure what can be done if they don't hear it.
