When I purchased the car I assumed it had the same adaptive cruise as my in-law's (2012 I believe) JX35. Their ICC comes to a full stop and will happily inch itself along in traffic all day.
The ICC in the Q50 gives up control at a stop, and when I looked at the manual for the new QX60 their system seems to be the same now. I then checked the adaptive cruise manuals for the Mercedes CLA and BMW 3 series and they all seem to give up at a stop.
Since the adaptive cruise can be made to inch along in traffic, does anyone know why most manufacturers aren't offering it anymore? Was this some government thing or a manufacturer's agreement?
The lack of the full stop and go is a bummer though. I can't tell you how nice the JX35's ICC is in NYC, DC, and CT stop and go traffic is.

I noticed this too and was depressed when I realized it wouldn't start up after a complete stop. I despise stop and go traffic and sit in it all the time which is one of the main reasons I got the technology package :mad:

I also have a BMW with ICC. In that case, like the Q50, it will bring the car to a stop. The difference being it will hold the stop indefinitely. If the car is able to move again in under 2 seconds, ICC stays active, and slowly accelerates the car. If the car sits stopped for over 2 seconds, the car will not move by itself when there is room in front. A tap on the accelerator is needed, and then ICC is woken up and takes over.

I was a bit surprised that the Q50 behavied differently. I imagine both Infiniti and BMW are trying to account for the possibility of the driver 'falling asleep' while stopped, and just go about it in different methods.

I have not been in true stop and go traffic yet with the Q50, but when I was with the BMW, ICC was still a bit of a nuisance in situations where I would be fully stopped for 2+ seconds. I suppose the Q50 may be just a tad more annoying in a similar situation.

What a bummer. I didn't even know this was a change from prior models :( Would have been nice to stop and go

It should work down to a full stop. But it cancels itself if you're stopped for more than 5 or 10 seconds. Is this not what people are experiencing?


FWIW, I think it also can not be set above 90mph - not that you should be giving up control of your car if you're going north of 90.

The frustration here is that ICC cancels itself if the car comes to a complete stop for even 1 second.

Since they rolled out the full speed range ICC (2009 FX50S) it pauses and holds for 3 seconds and beeps as it turns off. I have tested every single model equipped with it since it came and they all do work the same but can get a little annoying in stop and go traffic that plagues most of our areas.

i have been curious what happens when the ICC stops the car on a hill. Does the HSA (Hill Start Assist) take over?

Hmm I don't remember it waiting 3 seconds or hearing a beep on my Q50... I'll have to test it later.

There is a slight beeping sound, but probably hold it for 1 second or less. Certainly not 3 seconds. It can get dangerous because if you don't pay attention and you can end up rear end someone car. Infiniti need to make it hold at least 5 seconds with constant beeping sound until you press the brake or accelerator. Not sure if this can be implement by software update. If it could, they probably would have implement it already. Overall, it work great at cruising speed or slow moving traffic. Luckily for me, most of my traffic is slow moving traffic, so no complain from me.

Another senior master and I rode around in a loaded Q this afternoon to play with the ALC and ICC and we timed it to three seconds stopped before the buzzer beeped and the brakes released.

If there is any discrepancy in any of the tech systems the system stops working and will store a fault.

I agree it should hold the stop at least longer. It's cool that it will slow down to a stop, but deceiving when it lets go if you weren't expecting it. Creeping along in slow traffic, it's actually pretty dangerous and I think requires even more attention to be ready to apply the brakes when it stops. Hopefully they can tweak it, but I'd highlight it as a safety issue.

It's actually similar to the way it works with the backup collision avoidance, but I guess the beep and sudden stop is more alarming and causes a more natural reaction to slam on the breaks. Although, when I was first playing with it I didn't realize it let go (maybe there's slightly more delay there). Luckily it was just a plastic trash can in my driveway.

I'd have to agree that if it held the brakes a little longer it might not be so bad. I like the idea of holding the car at a stop until its clear to drive or until you press the accelerator. There had to be a reason for removing that feature. But I would be happy if it implemented at least a 5 second or 10 second hold before releasing. It would make driving in traffic a lot easier and also serve more of a purpose.

Isn't it ironic that we've come to the point where we are now at the point where there is criticism because we have to have our foot on the brake to keep the car from moving? I hope that those who don't like it aren't lamenting the coming of the self-driving car. :D

Lol its funny when you think about it. Definitely first world problems were experiencing lol

Ya, it's funny, but if it's going to do something automatically for you, like come to a stop, it should stay stopped. The fact that it times out so quickly and starts creeping forward is somewhat counter-intuitive and dangerous.

I think just a slightly longer time before releasing the break would help.

I just don't know how full stop and go allows distraction. It isn't like you can stop steering.
Also, does anyone know if the Emergency Forward Braking works against stationary objects? In the manual it doesn't say that it doesn't work against stationary objects like FCW.

The IIHS, in this preliminary report, slams the JX. I almost wonder if they had the active tech turned on?

You can stop steering with active lane control and lane departure prevention...
