burning smell in cabin
When starting the RX, I smell something I would describe as "burning insulation".
It happens only first 10-20 seconds after the air comes out from the vents, and then the smell disappears. The smell is stronger after prolonged parking- it is the strongest in the morning and less noticeable after I start the RX 2-3 more times ( I usually make 6-8 short trips during the day).
The smell was very strong awhen I started the RX first time after it was parked for one week (while we went on vacation).
There are no warning lights, and the vehicle runs just fine.
I pulled out the carbon cabin filter (changed about 3 mo ago) - it did not smell and was very clean still.
any thoughts?
I am hesitant to go to the dealer-afraid they will rip apart the dash, which they probably will not be able to put back together without having rattles and noises after.
The smell comes from the inside- there is no smell under the hood after I start the RX
thanx

Thanks to every one for your replies. No smell from under the hood. As per shop foreman, it is a common issue with new Lexus vehicles because in hot weather the climate control system goes into recirculation mode. The water in the evaporator box cause mold and mildew build-up. The dealer will clean the evap box through the drain line The issue is documented and is not specific to lexus but the newer ones apparently develop the issue sooner.
