NHTSA Complaint #11542763 — 2021 RAM 1500

I started smelling coolant inside the cabin of my 2021 RAM 1500 at approximately 49000 miles. I'm the original owner. After waiting for over a month before the dealership could look at my truck, I was told my heater core needed replaced at a cost of $2369.52 and charged a diagnostic fee of $201.49. Because the basic warranty had expired, and the truck is less than 3 years old, I called Chrysler Customer Care for assistance. They opened case number 87011413, and was assigned a case manager. I was told I would be contacted in 1 to 2 business days. It has been 3 weeks, and I still haven't heard from the case manager. I tried calling Customer Care several times but I only get voice mail.
