Noticed yesterday a nasty smell coming from the engine compartment, seems strongest near the fan. Looked everywhere without removing anything except the Turbo intake manifold cover/shield. Didn't see anything. It doesn't smell like a dead mouse, I really can't tell what it is...never smelled anything like it before. I suppose it's organic... It's a 2021 GT with 11K miles, lives in a climate controlled garage and has only spent a few nights outdoors. Atlanta suburbs. It's been in the garage for 2 weeks without being driven. Do these cars have any history of this, anyone out there ever experienced anything like this?
