2017 Sonata Sport with 2.4 HVAC fan speed fluctuates. Took delivery of the car in July. When I have the AC on during a hot day and I take my foot off the gas, the car slows down to say 28, the AC cabin fan speed increases. It is not a slight increase but sounds like the speed was turn up to the next level. Very annoying and distracting. Dealer could not duplicate problem because the weather is now cold. Anyone out there experiencing this on their 2017 Sonata with the 2.4 and base HVAC system??
