My cruise control actually has a button (may not be the right word...?) for acceleration and one for deceleration. Sometimes while I'm pressing the acceleration button, the whole cruise control function turns off.
Yup, 2011. THANKS all for your responses! Maybe mine's just having a bit of a hiccup.
Just a thought... since the on/off and increase speed buttons are literally right next to each other, maybe it's simply that you had an accidental bump of the on/off switch at a time when you were feeling for the increase speed button (one of those, new vehicle, getting used to the feel moments). Hopefully, it's something that simple.. and BTW.. really like the color
