I have a 2013 Ford C-Max Energi (plug-in hybrid) with 44,000 miles on it. I bought it in 2016 and it has always had an annoying smell when the engine turns on while the heat is running, a lot like gasoline. I most notice it when the electric heat is running and the engine then turns on. The smell dissipates pretty quickly.
For some reason this hasn’t seemed like a problem until now, but thinking about it now I feel like it’s probably not a good thing to be breathing that, and I confirmed on the model owners’ forum that it’s not standard behavior.
Does anybody have ideas what could be causing this?
