2015 JEEP CHEROKEE Forward Collision Avoidance Warnings Problems

this vehicle shows all recalls have been completed. however, every time it rains, the hatch compartment fills with water. 10/30/2022, my electronic parking brake light came on and the vehicle was stuck in park. Once we got the car home, I opened the hatch and removed the spare tire; there was standing water in the area from rain. This morning I was leaving for work an d the following lights came on; 1) Service 4WD 2) Service electronic Parking Brake 3) Service Airbags 4) Service Front Collision system 5) Service auto start stop 6) Adaptive Cruise Control not available 7) cruise/ fcw unab=vailable- service required This vehicle has been a complete nightmare.

No previous issues with the vehicle until this incident. That morning on my way to work my check engine light came on. I called my husband and he said he would check it out that evening. Got to work fine. When I went to go home from work my car was acting strange. The ac or blower and the radio wouldn’t come on at all until after about 15 minutes of driving. About 5 minutes later my brakes wouldn’t work at all trying to stop at a light and I ended up crashing into a car that was completely stopped while going about 35mph. My front collision detection didn’t go off until I was about an inch away from the vehicle and the automatic emergency brake didn’t engage either and normally if a car is turning slowly 30 ft ahead it will slam on the brakes.
