2020 Ram - Smells like burning plastic

[Rambo 2024]

My 2024 Ram Laramie Etorque now has 8000 miles and the burning smell happens only when I run the heater. It’s a plastic smell, not coolant which has an entirely different smell. What drives me crazy is the manufacturer has to know about this as do the dealers. I am about to make my first dealer appt to see if I can get assistance. The smell is unbearable and I’m sure not healthy. If I get anywhere with this I’ll be sure to report back.

Curious to know how things turn out… I seemed to remember having my heated seat on high when I first noticed the smell and wondered if the plastic was melting underneath my seat…it’s a very specific smell…like burnt plastic carmel with a little cat **** mixed in

Heater core leaking. Very poor design. The two aluminum pipes that are connected to the heater core have o rings in them so they can rotate for some unknown reason. After expanding and contracting for a period of time they begin to leak a little and then a lot. Very labor intensive to remove entire dash, steering column and HVAC box to replace heater core with the same lousy designed part. My 2019 with 70k miles began leaking all over passenger floor. Out of warranty now so I’ll be out about $2k for the repair.View attachment 194457I'm going to try and epoxy the fittings with a heat resistant epoxy and see what happens. I have radio and glove box out and can get to the fittings. I bypassed heater core at water pump so I could still use the truck to get to work. Waiting 24-48 hrs for epoxy to harden then I’ll hook hoses back up and see what happens.

Hey did this work?

I’m running into the same issue 2021 ram bighorn with 65k miles everytime my air conditioning turns on and especially with the heater turning on the inside of my truck smells bad with burnt coolant smell I’m dredding taking it to dealers. But need it fixed before warranty runs out at 75k. Wish me luck.
