NHTSA Complaint #11556692 — 2017 FORD FOCUS

I purchased my 2017 Ford with approximately 300 miles on the speedometer. Have driven my vehicle with care and routine maintenance getting well over 40 miles per gallon. Twice I have had a issue with the clutch and/or transmission under warranty. The car would shutter and vibrate while shifting from 1st gear to 2nd gear and increasingly become worse the more driven. Whether the car is warm or cold, still it would shutter. Was a hassle getting the dealership to fix this issue both times, but got it done. The same issue is starting all over again at 91,000 miles and the warranty is now void. Hoping this repetitive issue can or will be repaired. Thank you
