From time to time I get a pretty noticeable honey-like aroma coming out of my vents. Although it smells like honey to me, a friend described it as "old lady lavender".
I have a 2011 Nissan Sentra with approximately 45k miles.
I had the dealer perform an inspection, which included the cooling/radiator system. They did find and replace a cracked axle boot, but the smell persists.
The smell is intermittent and I cannot reliably reproduce. Sometimes it occurs from a cold-start, other times I won't notice it until I'be been driving for 20 minutes. It doesn't seem to be related to the air temperature or if the AC is on or not.
Should I have someone else inspect the radiator? What are other things that I should have inspected as possible culprits?
