My car smells like antifreeze but no leaks or running hot did get a recall letter about this problem if not covered under recall is it covered under bumper to bumper warrenty

Your heater core leaking. Some have a hose to outside. So anti-freeze going on ground. Check on the ground.

The foirst question I would ask is when you were filling your radiator recently did you accidently spill fluid on the engine block? If that is the case when your engine heats up to operating temperature you will get the odor of the antifreeze as it boils off the engine. Give your engine a thorough wash and see if the smell goes away after getting the engine back up and running.If the smell is still there determine if you have a leak by taking note of the level of the overflow tank when the engine is cold and then drive it for a few miles and then let the engine cool back down to the same temp as when you checked it the first time. (Usually just note where the level is in the morning the first day then drive it normally for the day and park in the same spot that evening and check the level the next morning) If you have a leak you should see a drop in anti-freeze level between the two readings. If you do have a leak you might want to check the oil for traces of anti-freeze in the oil. (Not a good sign) this might mean a problem withing the engine which should be covered by your bumper to bumper warranty but everything depends on the fine print on your warranty. (ALWAYS READ THE FINE PRINT FOR THIS TYPE OF WARRANTY)
