 I have a 2013 Ford Fiesta. In the 12 months I've owned the car we've continuously had electrical and transmission issues.  It shifts hard or not at all, the lights go out with the heater is on, the heater goes off when the radio is on, the car turns off while stopped at red lights, etc.  A ford dealership finally changed out the transmission last month after I had it in multiple times but only did so when I told them I knew it was under recall.  They did not offer this recall to me.  They blamed the electrical issues on the transmission.  They finally changed out the transmission in Jan 2018. The problems came back three weeks later and the dealership blamed it on the alternator this time.  We paid the $500 to have the alternator changed and the car is still shifting hard, running at 4000 rpms in 1st, 2nd, 3rd gear, dying at red lights, etc.  How do I solve these problems once and for all you ask?  Sell the lemon and move on with my life.  Or at least that is my plan.  Ford has not been helpful at all in solving this problem once and for all.
