NHTSA Complaint #11533104 — 2017 CHRYSLER PACIFICA

I purchased 2017 Chrysler Pacifica in 2021, I started having issues my vehicle after my 30 day warranty expired it seemed on and off at times now more noticealbe the START/STOP feature failed to work properly. The vehicle stalled when the brake pedal was released I had to restart the vehicle. The contact disabled the START/STOP feature. Additionally, while driving at night in the rain the vehicle acted up or started to blow hot air from the AC unit at 75 degrees with out the option to change it only way to restart was to turn on and off the vehicle. I also had problems with the coolant being low, and coolant was added. The vehicle was taken to an independent mechanic who informed the contact that the check engine and coolant lights were illuminated. The battery was faulty, and the START/STOP feature was inoperable. A pressure test was performed however, the mechanic was unable to locate a coolant leak. The vehicle was taken to two mechanics EGR cooler valve was cracked and my engine was damaged as well as the pistons. The vehicle had to have the whole engine replaced which was an expensive expense I had to pay out of pocket, the dealer did not cover the damage. The manufacturer was notified of the failure and referred the contact to NHTSA for assistance. The approximate failure mileage was 104, 000 or so. I still do not feel safe using this vehicle it is my family vehicle, please advised. I have invoices but not at the moment I had to replace the engine, the battery, the coolant container, and the radiator for a total amount of about $5000
