I was driving today, stop-and-go, slight decline, when I heard (or felt) a slight clunk. At this time it felt like the car was moving forward sluggishly. After 10 seconds or so I realized it was now in "B" mode ... engine braking. Has anyone else seen the car just go into "B" on its own? I def. wasn't anywhere near the tranny when this happened.
I found myself in B by accident once, but I am sure I accidently bumped the gear shift. It dumps you out of cruis control too.
