Mine started to stutter when the wipers get close to it's highest point. It stutters sometimes when it't wet, but most of the time it does not. My 2015 LX CVT has around 33,000 miles on it. It went that far without a single stutter but then it started. Hmmm.... I live on the West Coast and go up and down I-5 and US 101 all of the time.
