Has anybody else noticed that if the brakes are applied by the dynamic cruise control, they don't get used again in the same cruising "cycle?" Seems kind of dangerous, if you've allowed yourself to be lulled into complacency because you "expected" the brakes to be applied. Here's what has happened to me twice in the last couple of days:

I'm cruising along, FCW, BSW, and BSI turned on. DCI turned off. Dynamic cruise control set (to 57 MPH, if speed matters). Guy in front of me slams on his brakes...so my car does the same. I never disengage/turn off the cruise control, though...the guy in front of me turns off, leaving the lane clear in front of me. So my car starts accelerating again...next thing I know, somebody swerves into my lane right in front of me. Guess what? My car doesn't brake again.

Has anybody else noticed this? If so, I wonder why this should be. Maybe the logic is that braking only happens if you are at your preset cruising speed (i.e., the speedometer and digital cruise speed match)?

Please read the manual, page 5-53 specifically indicates that the ICC may not be able to recognize fast enough if a car swerves into your lane.

Ok. Thanks, I see that. Nevertheless, I don't think ICC is able to control the brakes once it's already done so...even if there is sufficient time. I just did another test this evening...it'll drive right into the back of the car ahead, unless I intervene. Weird.

My ICC brakes all the way down to zero and starts up again as long as I am not stopped for more than a few seconds. Brakes will also work multiple times. I don't see the problem you describe. One observation, however, is that if a car moves into your lane, even if it is close, if it is moving faster than you, the ICC does not bother to slow down or react too quickly. If a car moves into my lane even far ahead but is moving slower than me, the car takes action and starts slowing down. In my opinion, my ICC is driving like a very skilled driver and is not annoying at all.

Kevin...just out of curiosity, do you have DCA engaged? I do not. Could that be he difference? Just tried another test today: Cruising along, eventually the brakes had to engage (caught up to traffic), and then the car sped up again after everything thinned back out. Then about a half mile or so later, I came upon cars stopped at a red light. If I hadn't stood on the brakes, I'd have plowed right through them.
