Bought new on 12/25/2015. Started hesitating starting off, skipping like spinning tires. Got worse and like going over strips in the road. Akin replaced the computer and the clutch 9/2016. Did fine then started again. Had it checked and could not make it duplicate the problem (01/2017). Just this week (04/06/2017 it started doing it again, and quickly increased happening. 04/07/2017 was so bad it would not change from 1st to 2nd gear and now has a scratching/rattling noise. Called dealer and service dept. Says to call in the morning and set appt. To bring in. Had husband riding this time and it is the transmission. Also has a slight drop or hesitation while driving as it seems to be dropping back in power and then picks back up. Very dangerous and scary. This happens starting off from a stop, turning from stop, going down the highway. I did not have the air turned on!.
