Adaptive Cruise Control Following Distance

YukonRon · Nov 29, 2014

New 2015i Yukon Denali owner here. I've been trolling the Forums for a bit for good info. so thanks to so many incredible posts and posters! So much valuable information!

Absolutely loving the Yukon but one of my few gripes is the Adaptive Cruise Control following distance. Even on the default "Far" setting I find the following distance way too close, especially at the 75 MPH highway speeds in my state. I'd estimate that the ACC keeps me roughly 30-35 feet off of the bumper of the car in front of me (roughly 3 car lengths), which is just too close at those speeds where you are covering 110 ft./second.

I'm starting to second guess my excitement about the very expensive ACC system in the Yukon. I've had other cars with the same feature and never felt on the Far or Medium setting that I was following too closely at 75 MPH highway speeds. Wish I could adjust it much further out.

Anybody else feel the same?

My jeep allows for one two or three car lengths in following. Remember that the auto system can act faster than you can.

Adaptive Cruise Control - Tooooo close

Took delivery on 2015i Yukon Denali on Monday and made a 250 mile trip on Wednesday - including two lane roads and Interstates. ACC works great but at the "Far" following distance the gap to the vehicle in front is 1 second. It is the same at any speed. Most pros teach a following distance of 2 - 3 seconds. I'm not comfortable with 1 second so ACC is an expensive and useless feature until GM makes a safety change. The dealer told me not to hold my breath so I started a complaint with a "case number." The GM person also said not to expect much. Hopefully someone at GM will realize an option to increase the following distance to something safer might be a good idea. I'm hoping someone from GM follows these forums and might elevate this to a higher level.

My 2015i adaptive cruise control gives me a following distance of 2-3 seconds. I usually leave it on the "middle distance" option, but put it on the furthest during inclement weather.

EMTPete - thanks for your reply. Please do me a favor and double check your following distance in seconds. Mine is one second at any speed which is too close for my comfort. Your 2-3 seconds at the middle distance and longer at the far distance would be just right for me. If you can re-verify your following distance I'd be really grateful. Thanx!! Gary

Let's just say that I have had prevously had speed detection training. My following distance with the adaptive cruise is definately at least 2 seconds from when a car in front of me passes a point until I pass the same spot. I would guess I usually notice a following distance of about 6 car lengths on the highway. This may not necessarily be typical for some, but is what I have been getting.

Adaptive Cruise Control

Could others with Adaptive Cruise Control on their Yukon Denali share their following distance in seconds in the "Far" setting? Mine is one second which is too close - it is one second at any speed so the higher the speed the greater the actual distance - still too close for my comfort. Others have said 2-3 seconds on their trucks which would be much more comfortable for me. Thanx!!

Mine is about three seconds

Have 22,789 miles and maybe 14,000 on acc and works great ,now is like 1-2 seconds delay for adjustment but work great.

I personal use "far' which is about 5 cars on rainy day and medium for dry condition.

Adaptive Cruise Control - 2015i Yukon Denali

Could someone time their following distance in the "Far" setting by counting "one thousand one, one thousand two, one thousand three" to determine the number of seconds it takes for your truck to reach the point where the vehicle in front of you was when you started counting? It really doesn't matter what your speed - the truck will always follow by a given number of seconds. I'm looking for accurate answers because GM is not providing this information. Thanks!
