Adaptive cruise follows too closely

Recommended Posts

Posted (edited)

2015 Yukon Denali.

On my other vehicles the adaptive cruise control is a very nice feature, but on this truck it is terrible.  Even at the farthest setting, it keeps creeping up on the car in front until it's dangerously close.  I'm talking 10 to 20 feet away from the car in front, even at highway speeds. 

Also, it seems to accelerate above the set speed to keep up with the car in front.  I'll be cruising along at 75, set at 75, and as soon as a car pulls in front of me it abruptly accelerates to 77 as soon as it recognizes the car. I find this very strange.


In my previous car I loved adaptive cruise.  In this one its unusable.

Is this the same for anyone else?  Or does anyone know how to fix this?

I did not know a 2015 had adaptive cruise control.  My 2015 Sierra Denali did not have it.   Thought that cam years later?  My 2021 has it and I never have any issues.
