Had owned the Durango for 2 months. I was pulling into my in-laws' driveway... driveway a bit snowy/slushy, but nothing major. Was going very slowly, obviously, being in a driveway with several cars and trying to pull up behind my FIL's car... I was almost completely stopped, when the car suddenly accelerated. I took my foot off the brake and put it back on again as quickly as I could, but it still slid into my FIL's rear bumper and cracked it.

At the time I wasn't sure whether the acceleration had been in my imagination, thinking perhaps it was just a skid that had happened so fast that I didn't understand what was happening, but it happened again the next day at an intersection I was approaching very slowly... right before I should have come to a complete stop, the car surged forward (and this was on a slightly uphill slant, so it was not skidding forward or anything.) I took my foot off the brake and then put it down hard again to stop. Thankfully the car approaching from the left wasn't in the intersection yet. My SIL was in the car with me then and I said, "Did you feel that?!" She said, "Yeah, what was that??" I told her it was just what had happened the day before. It hasn't happened since, however, (this is 2 months later)... so I am reluctant to take it in, as my guess is they probably won't be able to find anything wrong with it. Both times it happened on snowy/slushy ground, at very slow speeds (under 5mph), and suddenly accelerated just when it should have come to a complete stop.
