First time off the lot on the drive home about 20 miles. The battery was at 0% so we drove it home in E-Save mode with Max Regen activated. Upon pulling it in the garage it smelled bad and the engine was extremely hot. Could barely touch the hood! Does anyone know if this is normal-like a break in thing or should we be concerned? BTW temp that day was only around 70 degrees.

Do you remember what your water temp gauge was reading?

I do not. I'll pay attention next time and look at that.

You don't need to use e-save when the battery runs out. It just turns into a hybrid.

That doesn't sound normal. I take it you weren't in 4L? There should be gauges you can pull up in the off-road pages.

As someone else said, your best option is hybrid mode. ESave is like a special case use for when you want to use the battery later.
There is a smell for a couple hundred miles. Just normal break in stuff.

Can also use ESave mode to back charge the battery when you battery is depleted. just depends on your settings

To answer your question I also had that smell after my first two drives. cant speak to the heat from the engine since i didn't go touch the hood but the smell hasn't returned. I imagine @FirstF80InSpace is correct and it may just be the cosmoline.

Thanks all. Hasn't been excessively hot since then. Maybe just being paranoid.

Engine smell perfectly normal for new vehicle. Mine did it too and I suspect smell will last longer as my dealership fully charged the battery and engine barely runs or gets hot when hybrid batteries are charged.

I've never heard of cosmolene until this thread.
Somebody is dating himself, hasn’t been used in 50 years. A mess to get off. Sticky and messy, like a waxy, tar substance.
From Wikipedia
Use. The most common use of Cosmoline is in the storage and preservation of some firearms, hand tools, machine tools and their tooling, and marine equipment. Entire vehicles can be preserved with cosmoline.
used to be used as A Storage preservative for Army guns 50 years ago/
You probably smelled some oil/paint/rubber/glue getting burned off the engine first time it got hot.

Cosmoline sort of became like "kleenex", as in kleenex refers to a specific brand but everyone uses it to simply describe tissues at this point. So yes cosmoline is no longer used but its been replaced by various other rust inhibitors, instead of learning all the varying names everyone in the car biz still just calls them all "cosmoline"

So you're technically correct, which is the best kind of correct, but at the same time its a little pedantic given its common usage these days lol.
