Possible heater issue, occasional "burning smell" on Max setting.

I am hesitant to call this a problem, and am wondering if anyone else has noticed this? Perhaps this will go away over time (car was purchased end of Nov, only 3500 miles).

Several times now I have been running without ERDTT. Outside temperature was upper 40's, and I had the heater on Max for a quicker cabin warm-up. After about 10 minutes I noticed the odor of "hot-electronics", seemed to diminish when i switched to eco. I assume the Volt HVAC system incorporates a resistive heating element, and wonder if this is what I am smelling? Have others noticed this? Perhaps it will go away over time, or ....?

You want an 'electrical burning smell' to go away over time!?!
The resistance heating element is under the hood and it warms a coolant loop. When the engine is on a valve opens that loop to the engine.

I smell a big red flag.

Use that warranty. Figure out if it's repeatable so you can show the dealer.
