I sure as heck wouldn't trade-in solely because of CVT worry. Pretty sure any late model 6, 7, 8, etc.. speed AT will be a pricey a component to replace or repair should a problem arise as well.
If you're just not happy with the vehicle or sick of it, and doing so won't jeopardize your finances, why not spur the economy a bit and get something else. I know I've been down that road a few dozen times. lol
