I have adaptive cruise control on a 2007 DTS and I really like it. It does require some experience and you must remain alert but it is very convienient. However the radar line of sight seems to be off to the left and you need to line your car up slightly to the right of car in front of you, otherwise it will not pick it up until you get fairly close and then it applies brake. It is not too bad but if the car in front of you is close to the right side of the road I may have to drive very close to the shoulder of road. I have asked the dealer if the radar can be adjusted but they do not know. Would appreciate any ideas
Interesting point. I wandered from far left to far right in my lane while following in ACC mode last night and the speed never varied so I would say that what you saw is abnormal.
Now I have to admit that I normally run around with the spacing being set to minimum because if you widen the space you are guaranteed that some idiot will pull in front of you and really upset the ACC.
I will open up the spacing (temporarily) and revalidate that things work in that mode also.
One of these days when I have the time I will get with my local sheriff dept and arrange some testing to see if we can determine why my ACC declares false emergencie and brakes as hard as the system allows when the car is swept by police RADAR.
That would be a good thing if I could get it to do that say a mile out instead of only happening when I am within a couple of hundred feet or so.
M y dealer says the adaptive CC is 100 percent. The local police don't want to discuss the problem and I am sure GM feels the same. I wouldn't care if it only affected me when it hits. The problem is the car starts braking when there is no apparant reason for it and sooner or later it will affect someone who won't have the presence of mind to either hit the gas or turn the CC off and override it before you get rear ended.
So I am going to report the problem to the NTSB. Hate to go to the gumment but I wouldn't have a clue as to who else I can involve.
As for aiming, I know that isn't it. The 3rd episode happened when I went by a parked police car that was to the right of a 4 lane road and I was in the innermost lane. Brakes went on as I was parallel to him. Came right back off pretty quikly as I passed him at 65 MPH.
Also, II am sure that the alignment is perfect. can sit behind a car going thru the Sunpass lane on the expressway and the car will slow down as the one in front of me slows down and tey pick up after him when he clears. My car never gets distracted by the sides of the gate or the top of the gate.
