ICE engine kicks on and driving on freeway for 10 minutes when strong smell of burnt plastic and or rubber permeates cabin. Overwhelmingly unpleasant for the duration of the drive. Is this normal? Has anyone else experienced this for a prolonged period of time. Vehicle history is over 1000 miles and has happened everytime ICE engine kicks on and driving over 60mph. Highly unusual.

Coolant level is normal, no warning signs on the dash. No smoke coming from under the hood or anywhere else. Already taken to dealer and they stated it was normal? Fans running when ICE kicks up are extremely loud. Especially the rear right sided one.
What is the highest coolant temperature fellow members have seen on the volt? After a 230+ mile continuous drive on freeway mostly, mine went to 240F. Smell was toxic.
Dealer says a lot of the stuff should disappear after driving significantly more (5000+ miles)

apparently normal for bad smell, high coolant temp, wild mpg swings to occur in the beginning

It's not like the warranty expires anytime soon so should be fine
with 1500 miles on the clock, odds are a good portion of those are EV miles, so basically the engine is still brand spanking new with all the coatings/lubricants/etc.

I had the same burning rubber smell too when I would pull into my garage if I happened to be on ICE power coming home, I do about 70% of all my miles in EV though. Either way, you don't really have anything to worry about, mine did the same thing and was fine after a while.

heh my 2017 is already about to hit 16,000 miles :p
Wow, 70% of 16000 also in EV only? That's amazing either way. What (if any) problems have you come across through 16,000 miles if I may ask? Any issues with battery, coolant, etc? Have you even had to do your first oil change?
Not sure about plastic smell, but I and many others have reported a slow oil leak from poorly sealed oil pan. The oil drips or is wind blown onto nearby exhaust and causes an odor when on ICE. Took it to the dealer and they had to remove and reseal the oil pan. Seems fine since (about 5 months ago). I have about 7500 on the car now.
when did you first notice the oil leak/poorly sealed oil pan in terms of mileage if I may ask?
