This has to be something that someone else here as experienced, as I have a friend that experiences it in her '04 Corolla...
Occassionally -- well, rather infrequently -- when I come to a full stop, and my foot is still holding down the brake, my 4Runner ('07) will suddenly lunge forward slightly, feeling as though I just got lightly 'tapped' from a car behind me or something.
Certainly doesn't seem like anything serious...but was just wondering if anyone else has experienced this, and knows what this is...
Thanks
