My 2016 ex AWD is having some cruise control issues. Every now and then the cruise control will not shut off when it is set after I try to use the cancel button. I have found that it happens usually when it’s cold out. I have to hit the brake or turn off the cruise control. It doesn’t always happen, I’m at 55,000 miles and close to using my 5 year 60000 warranty. How can I get this fixed under warranty if I can’t always duplicate the issue?
