The cruise control on my 2019 XLE will fluctuate by one or two miles per hour. For example, if the cruise control is set at 70MPH and I am going up a hill, the speed will almost always go down to 69MPH and sometimes to 68MPH. When going down a hill, the speed will almost always go up to 71MPH and sometimes to 72MPH. I have not had this experience with other vehicles. Have any other CHR owners noticed this phenomenon?
