Who thinks the cruise control system in the VF sucks?

    Personally it needs some more algorithms or something to help it along.............just not fluid in its thinking.....lol

    Also, i reckon it makes the engine use more fuel......compared to driving by foot and keeping to a set speed etc.......

    Thoughts?

    I wouldn't characterise it as "sucking", if it were that bad I wouldn't use it (and I use it a lot).
    I agree it'll drop 5km/h before stomping the throttle a bit too much & by the time it does that stomping you're nearly at the top of the hill so you end-up doing 10km/h over just as a cop goes the other way ... it's nowhere near as accurate as various rentals I've driven from other manufacturers.

    Never had a problem with the cruise control in my V6-engined Calais V. On flat or uphill roads it keeps the car's speed within +/- 3 km/h of the set speed. I just wish it did the same on long downhill roads, instead of letting the speed build up. I either have to use the gears in Sport mode to slow the car, or tap the brakes which of course cancels cruise control. Generally though I think it does a good job, especially on long country runs when it's all too easy to let one's speed creep up without realising it.

    It speeds up nicely going down hill :D

    My S2 SV6 is the same, quite accurate at maintaining speed up and down small hills, but will run away, it doesnt brake like my E3 Clubby down hills.

    I didn't know it had cruise control, what's it for?

    Cruise control will not brake going down a hill unless you have adaptive cruise control with another vehicle in front of you. VF does not have adaptive cruise control.

    What - really?!

    Since we're talking features that VF's don't have ... this isn't always correct, quite a few cars will use the ABS actuators to keep a car at the set speed downhill.

    cruise control works well but not market leading :eek:

    I would have liked a long up press to increase speed 10kph while a short up press to increase 2kph. Similar logic for down press speed decrease. Icing on the cake would have been more positive engine braking when going down hill with ABS intervention if needed so as to avoid speeding fines going down hill.

    That’s an easy firmware update for Holden to provide but Holden is Holden o_O

    It doesn't suck. And cruise control in the VF SII SV6 (in my case, Sportwagon) does not build speed on long downhill roads. It is one of the best and smoothest cruise controls I've had, even better than my previous VZ (which also did not allow speed build up on downhills). I live adjacent to a 4km downhill slope freeway, and it holds the road speed dead steady at 103km/h. It also holds steady coming back (uphill), with no pulsing or swap-outs of gearing.

    My return journey today from home to Mount Gambier (700km+) and back was on cruise control a lot of the time, only disengaging it for overtaking and coming into towns. Nothing to complain about.

    Seems engine type, engine tune and/or other firmware could have something to do with whether a specific car speeds up when on cruise and going down a hill... cause my Motorsport definitely increases speed in such instances...

    Would I describe VF cruise as sucking... no, but it definitely isn’t a leading edge design...

    on the flats its perfect. just wish we had adaptive to combat the idiots constantly going up and down on open road.

    Ah, well now you're quoting a specific example where the effect of gravity in speeding up a car is counterbalanced by the air resistance when travelling at highway speeds. It also depends on the degree of slope of course; when I travel on the South Eastern Freeway from Adelaide to Mount Barker at 110 - 115 km/h there are still several steep downhill bits where the car will pick up more and more speed, despite cruise control being on (and set at say 113 km/h).

    a Motorsport is not the same as bog-standard VF SII SV6, so you might have a point about differences in

    A Motorsport is not the same as a VF SII SV6, so you might have a point, IDK.

    Thank god it doesn't have adaptive cruise control. I have a work 2017 VW Passat with it and it sucks.

    Er...what???
    Something's up. If somebody's VF (of whatever flavour) is not maintaining the set speed on a downhill slope, have the car checked. I have nothing to report to the contrary about demonstrated speed gains, downhill or on the flats in my own VF — I just sit back and admire how well it does the task. Believe me, where I am the Constabulary have a very low tolerance for anybody going faster than the set speed on downhills (by even a paltry 3km/h, which is described as being a "dangerous excess"!) and also uphills — yes, the boys in blue/black and hi-vis are at the top of the hill keeping watch on leadfoots powering up the last hill before home...

    I can confirm the Adaptive Cruise on the 2018 Tiguan is a right menace, too!!

    every automatic ve and vf i have owned going down hill will easily speed up 10kph over the set cruise control speed forcing me to use the brakes but this is on a pretty long decent(3km or so), over about 1km it will do it.
    the manual ones hold their speed a lot better in the same situation.

    my automatic colorado will go into gradient braking mode and maintain the correct speed on the same hill

    Yeah, right. That's why Holden specifically warn about the car speeding up downhill under cruise control (see extract from owner's manual). As yours doesn't seem to do it, perhaps you need to have the handbrake checked -- could be the linings are binding. How's your fuel economy?
