Very rarely, I'll gently apply the brakes, at speed, like a freeway off ramp and it acts like the ABS tried to panic stop by pulsing a couple times. It really gets your attention,, but the good news is the whole thing is over 2 seconds later.
It won't do it again for weeks, I've had the 2009 MMH for over a year and it's done it about 12-15 times. I'm wondering if it's a ABS issue, occasional reset or recalibration or maybe the regen braking doing a reset, as if the 12V battery got so low that something needs to get re-learned?
Thanks for any ideas.

 

Thanks for the reply, last time I went to the dealer the SM said to make an appointment for about a week out and they'll need to keep the car for a couple days so I've just been using this forum instead.
