NHTSA Complaint #11532416 — 2009 JEEP GRAND CHEROKEE

I just purchased this vehicle, in May 2023 and I have honestly had nothing but problems. I have no idea what is causing this but the speedometer/odometer does not work at all (all the lights and warning symbols work, cruise control doesn't work, TPM is lit up on the dash as I checked all the tires and all has same to, the key fob buttons worked when it wanted to (has NEW battery it was replaced 3'xs already) key fob would not stop alarm from going off most days and key fob would also not start my Jeep would have to keep trying before it did start and now IT DOESN'T DO ANYTHING. IT DOESN'T START DOESN'T TURN OVER NOTHING expect for the alarm going off non stop had to disconnect the horn and we pulled a relay to have it stop. We tried disconnecting the battery post to hopefully reset it, didn't work. I also had a res dot start blinking and I read up on all this and red dot is anti theft was activated. I been reading up on the reason and I keep getting the wireless control module and sentry key as the problem. I also seen that many other vehicles same as mine has had the same exact same problem. Some had theirs come up as a recall. Why is this vehicle listed as not having any recalls. Clearly something is going on with these vehicles that shouldn't be. I for one didn't cause this problem and I certainly can not afford to get this resolved on my own. I had my truck for only 2 weeks before it broke down. PLEASE HELP
