Have they checked the wiring harness? Also, the cost of a vehicle has nothing to do with whether or not it will have issues that can be easy or difficult to diagnose and repair. Actually, the more electronic features it has, the more susceptible it likely will be to certain failures. Have you checked to see if you qualify for a buyback under your state's Lemon Law?

I have had my 2021 almost one year. Only problem to date was the drivers seat airbag after about 3 months of ownership. Turned out it was a problem with the connector between the seat bottom and the seat back. Technician said he thought he fixed it, but he ordered a new harness and told me to come back if it did it again. He said that most of the problems are usually wiring or connectors, not modules. However many techs start replacing modules, so the problem persists. So far, no further problems and I did not go back for a harness replacement, figuring I best leave well enough alone.
During October of 2020, my wife wanted an EcoSport (not sure why). After about 12 months of ownership, the speakers quit working. I took it to a dealer and they ordered a module they diagnosed as bad. When it came in, I took it in for replacement. A couple days later, wifey was on the Interstate and the car would not stay at speed on a hill. It would run up to 5000 rpm's and still lose speed. BUT, did not throw a code. I took it back and got the standard "Drove it 40 miles and could not duplicate customer complaint". Funny, the Tech put that on the service receipt, but the miles in and the miles out on the receipt showed less than 20 miles driven. A little lie? Car still did it and I went back and complained to the Service Writer and asked that he or a Technician ride with me to experience the problem. He refused, told me there was not a problem and they would not work on it again. He also said that I was free to take it to another dealer.
On the way home, it started throwing codes for the timing sensor, airbags, traction control, a total of 19 codes. Took it to another dealer and the Technician found a naked spot in a wire, taped it up, cleared the codes and it has never had another problem. I strongly suspect that during the module replacement, the wiring harness was damaged.
Guess what? I have bought 6 cars from the original dealer, and will never go back on their lot. So the Service Writer's suggestion that I use another dealer was the right suggestion! No use to complain to Ford, as a bad dealer is a bad dealer and surely Ford knows this dealer is bad. I have actually advised two friends who were ready to buy a new Ford to avoid this dealer, and they took my advise.
A friend bought a new John Deere farm tractor. He has had problems with the hydraulic lift, failure to start and a couple other problems. Each time, it turned out to be a bad ground on some component. These new vehicles and equipment have many grounds at various points.
Told you this just to point out what the Technician said about my Explorer airbag issue, most of the problems are wiring related, not bad modules. Just think how many connectors and grounding points there are in the wiring of these modern vehicles.
