DH called me from the dealer. Apparently a partially-filled gas can in my trunk leaked out a bit. Yes, it's stupid I even have a gas can in my trunk, but it got switched over to the new car from the old car. I had it my old car because my gas gauge stopped working, and I was stranded on the road w/o gas twice, so I kept the stupid can just in case it ever happened again.
Service guy's solution? Febreze the crap out of the trunk!
Only me. This is third in a line of embarrassing problems that have happened to me in the past three months. Some of you might remember the laptop/touchpad incident of September and the chicken helper kitchenfire of August. I should not be allowed to touch anything.
