A friend of mine has a 2016 GX. It has what I think is a problem that the adaptive cruise control will not shut off no matter how long I press the on/off button. I called the dealer to see if I was doing something wrong but they want me to bring it in for service and they will troubleshoot the problem. So, I came here because I know someone has had this issue before me. Is there a trick to this or what am I missing?
