Rubber Burning Smell/Smoke from the hood

I had my normal Acura 105K maintenance in June 2019.  Spark plugs, transmission flush, AC and etc (my timing belt, water pump were done at 60K miles).  I was at the dealership on Tuesday, 8/13 for a leak in the front right tire.  There was a hole on the inside of the tire. I also had leaking grommet's on 2 other tires.  I opted for new tires vs. replacing one tire and 3 grommets.  I noticed a burning small that night when I got the car home. I thought it was new tires on hot pavement. I walked around the car and saw nothing and no strong odor. I noticed the smell again Wednesday. Today I drove to work and the burning smell was very pungent inside the car.  When I parked I saw gray smoke coming from the hood of the car. More toward the right side.  I was able back the car up and saw a black oily substance. I am thinking it was oil; I am not sure.  Do you think it is a seal? I have never had the issue with the car before.
