Did you find a solution to your loud noise? I experienced it over the weekend as I climbed a steep hill around 65-75 mph in my 2019 FFE. I thought for sure the CVT was about to explode. I'd let off the accelerator and the noise would die down, then accelerating again it would start to come back. Would love to find out what it was. Only have 18K miles on it so it should not have any mechanical issues.
