NHTSA Complaint #11704104 — 2016 JEEP CHEROKEE

So I was driving to work one morning and I pulled into the parking lot, put my car in park and a few mins after I get a message/ alert on my dash saying “service shifter”…. Indicating It’s the p1c86-1D, an electrical issue with the shifter display circuit. I took it to the dealership I bought it from (Della Chevrolet) they did a diagnosis. They said I needed to replace the whole shifter and if I did I’d have to pay over $1000 for them to do it and it wouldn’t be covered if it went out again because the car isn’t a Chevy… but long story short they told me that at any time my shifter can stop working.. an no got into park or drive etc… I’m not trying to be stuck there Also another electrical is when I got my car and when I stopped at lights my car would shut off for the eco friendly mode.. then one day it jsut stopped and I had one day where it tripped out… where it worked then didn’t. Also, when I’m driving, and I think it’s when I accelerate and when going a steady speed the car jerks randomly. Like jerks forwards
