Service Engine Light On problems of the 2020 Jeep Wrangler

Had it for less than 2 weeks (was brand new, purchased with only 43 miles) and decided to take it on a fall road trip. Halfway through our road trip (about 100 miles in) engine started �jumping� and �heaving� while in cruise control on the highway at 65 mp; then woudn't accelerate at all, and speed started to decline. Was very near an exit, so was able to coast in to a gas station. Electronic throttle control error code + service engine lights were lit. Attempted to turn off an on several times, hoping this was just some kind of glitch, but after multiple attempts it woudn't even stay started. While in park, after pressing "start" engine just kept jumping then automatically would shut itself off. Our whole family stranded hours away from home. Under 500 miles and it had to be towed in to the nearest dealership where it's been sitting for almost a week now and they still have absolutely no idea how to fix it. Was told that it lit up with so many error codes they have to get a special engineer from mopar to come out� just in shock that we're having this issue with a $65k vehicle. Very unsafe.
