I have a 2020 QX80 with about 3500 miles on it. I hate how my cruise control is working. On cruise on a slight hill, it will cause the transmission to downshift and rev up to about 4500 RPMs. Where if I do the same hill myself, I can easily maintain my speed without causing the downshift. Also on cruise on the interstate @ 80, touch brake for slower traffic, upon resume it again downshifts and revs up to 4500-5000 RPMs just to gain 5 mph. I find this unacceptable. I took it to my dealership and they said it was normal. Have any of you had any experience with this situation? Thanks for your input.
