Does your cruise control do this??
Does your cruise control not remember a new setting after accelerating?
Let's say I'm driving along the highway with the cruise control set to 65. I decide that 65 isn't really the speed I'd like to drive, so I give it a little more gas until I'm at 70. I press the SET button, and the CC is supposed to change its setting to the new speed, 70.
Instead, it reduces the old setting to 64. So when I release the gas, the car drifts down to 64. (Just what the person I just passed expects, no doubt!)
I know a quick tap is supposed to drop one's setting one mph, but if you're already going faster than the CC is set, it's supposed to remember that according to the manual:
I've tried holding the button for a variety of different durations. Sometimes it works, and the DIC simply shows the new speed. But other times when I press SET, the DIC will read CRUISE CONTROL DISENGAGED and then when I release it, it sets a new speed as I desired. And sometimes I have the problem above, which is very frustrating.
I had the entire left control stalk replaced a while back for the same problem, and it worked for a while; now it's back. Has anyone else seen this?

(ps:I already know I can tap the brakes or turn the CC off/on. But I shouldn't have to do that.)

I'm reactivating this thread because the problem seems to be happening more frequently.
Goal: While the CC is engaged, accelerate to a new speed, press the SET button and have the CC hold at that new speed.
Results: One of the following:
I've even held the SET button for several seconds, and upon release, it just drops one mph.

- The CC will set to the new speed. (good)
- CRUISE CONTROL DISENGAGED will appear in the DIC, then the new speed will display. (good.)
- The CC set speed will decrement one mph. (bad.)

Problem I have noticed was that when I am in 6th @ 65mph its at about 1200rpm (2.73 rear). The cruise will stay on for only a few seconds before deactivating. I can only assume it is due to the low RPM. I will try out your method and see what happens.

Every GM cruise control that I have ever had responds the same as s'noJob original entry.
I thought the set button originally sets the cruise speed, but until the cruise is released the set button just bumps the speed down and the resume/accelerate bumps the speed up from the original setting.

Going to have to check mine out and see what it does. If I want to set the cruise to a higher speed, I normally just tap the brake, accelerate to the desired speed and then push the set button on the stalk.

I've never had a cruise control that accepts a higher speed once it is set and I use the gas pedal to attain a higher speed. Either increase the speed with the resume / accel button or disengage and reset.
