NHTSA Complaint #11673816 — 2021 FORD EXPLORER

my explorer has a 10 speed transmission, and its REALLY heavy on shifting like it is missing shifts or slipping, it will shoot up in rpms to the 7-8k mark and jerk forward, this will happen every few minutes when varying speed, driving through residential areas or normal trafficways not including the highway, however on the highway it has a tendency to feel as if it loses power and regains it, dropping rpms and shooting back up to 4-5k rpm, and dropping back down to around 2k. today i had the incident where the car jerked hard after a shift, gave me prompts on the dash about seeing the manual, and that drive modes are not available. this has happened in the past month before multiple times, however this time i lost all power to acceleration going down the road, ended up just coasting to a stop on a road that speed limit is 55 mph. this made me panic, because i could have possibly been rear ended, or in any other case could have been hit if my car would not have properly been able to accelerate. the car has had similar problems reported from previous owners and they have been taken into a dealership for repairs of which did not fix the problem or the problem is reoccurring. there are no warning lamps prior to the jerkiness of shifting and loss of acceleration because of it. it will jerk a handful of times and eventually give me the "see manual" prompt after the initial problem was noticed, i decided to look online for answers as to what was wrong and it seems like this is a reoccurring problem with vehicles similar to mine. Hopefully it hasnt caused and injuries, but it definitely has the possibility to from what i have experienced.
