corolla 2014 when heater is on i get a smell like antifreeze inside what could be the problem
No. You may have a pin hole in your heater core. Pull up your mats and check for dampness on your carpets. Also, check under the hood and see if you can spot any leaks. See if you can see where the coolant hoses go into the fire wall to the heater core. Check for any leakage in that area. Hopefully it's not the heater core. Very expensive job to do.
I would take it to the dealer sine it should still be under warranty being its a 2014.
2 great answers above. If the car IS under warranty, don't mess with it, you may void warranty.
