Brakes pulsing with vehicle off?

[marin8703]

hey everyone,

Weirdest thing happened this mornig. As i went to the car and opened the hood to get ready to start changing my oil, i heard a quiet thumping sound. I narrowed in on the sound and it was right under the brake fluid reservoir, where the 4 little brake lines come out off.

The real crazy thing was that the truck was not started nor had it been for the past 8-10 hours. I hadnt even put the key in the ignition yet.

It thumps or pulses about once a second. I figure it was doing that all night, but how, without the ignition on or the key not even being put in; is ABS or TC active while vehicle is off and no key in???

Anyways once i put the key in and started it, then turned it off, it wasnt doing it anymore. I hope it doesnt do it again tomorow morning.

Have any of you people experienced this? Any idea why it may happen?

Thanks!

Wait, there is a thread here somewhere where another 3 is always found dead in the driveway. And they have looked to see why it was always draining the battery, but have never found the reason. So, Maybe just maybe this could be legit and that persons problem also.

yeah, i've seen that thread. could be same problem. Although i havent had any problems with the battery.

i know im not crazy cauze it happened again this morning and i got my neighboor to hear it too. Im expecting it to happen again tomorow morning so i got the camcorder sitting next to the H3 to record it and show you guys.

I wanna take it to the dealer, but i have a pertty good idea of what will happen. "we cannot duplicate the problem" bla, bla, bla.

ill get the video tomorow morning.

Great idea, but take your tape to the dealer. I have had all kinds of lil crap go wrong with mine. I like it, won't sell or trade it. But I do have my eyes on another Hummer. Good luck.
