Whining noise when driving up hills? I have a 2011 Jeep Patriot North from new and driven 97,000KM CVT automatic transmission. The noise sounds like a turbo boost kicking in type of whine, but I don't have a turbo. I was on cruise control with air conditioning running, but car still did the same when I turned those off. My car normally runs on flat roads in town and has no issues. I am retired and only driving the car from 3 to 5000km a year with an occasional once a year 800km trip to the mountains. I have not had any of the major services such as transmission, filters or belt changes done. Does anyone have any ideas what it could be? Thanks.
