Cruise Control problems of the 2014 Nissan Sentra

Had my car on the highway oct. 13,2018 for a 2hr trip. . . 1hr into trip and my car knocked off the cruise control and began jerking with rpms jumping up and down. On return trip it did the same thing, but no warning lights ever appeared on dash. When checked, no red flags and after a day or 2 around town rpms did not jump. Nov. 22,2018(just a little over 1 month) I put my car on the highway for the same trip and within an hour the car knocked off the cruise control, began jerking and rpms were jumping up and down. On the return trip back, 1hr and a half into trip, my car lost all aceleration power. . Pedal to the floor and it continued to drop speed from 70mph to 45 before I turned on hazards and stopped on the shoulder. Then finally the check engine light pops on! but my daughter and I were now stranded on the side of the busy highway. My car hit 75k miles during this 2nd trip, so first time was under 75k. After spending over an hour helpless, the car jumped back into gear and allowed me to drive it the remaining 20 miles, but once exiting the highway I could not acelerate to merge into street traffic and was almost rear-ended. There has been no mention of any cvt issues when I take it in for routine maintenance. Now it's in need of repair badly! no other choice but to take it in to the Nissan dealer ASAP. I've been loyal to Nissan for many years having had a 1995 and 2002 Sentra for years. . . I haven't even had this 2014 for 2 yet, and if being stuck on the side of the highway with a young child or almost being rear-ended due to loss of power to engine doesn't scream �we need a safety recall� what will??.
