Hello,

Been enjoying my 2013 ILX for some time now, but noticed a bad noise on startup. Only happens on the first start of the day and not again afterwards. I let it sit for several hours and couldn't replicate. But it has made the sounds early morning 3 days in a row, so I am guessing it is temperature based somewhat. When I start the car I hear a strange whirring sound like a bad small electrical fan in the car. Noise lasts for about 30 seconds then stops. AC/Heat was off at the time. It's also not particularly cold where I live (So-Cal).

Any ideas?

It doesn't like the starter sticking or the common VCT solenoid I have read about. But I haven't been quick enough to get outside of the car to listen to what it sounds like outside of the cab.

I would try recording the sound with your phone during a cold start.

So it took me forever to catch it on video but I finally got it. Usually only happens on first startup of the day and it needs to be sitting for a few days for it to happen. The last time this happened I shut the engine off but left the accessories going and the noise continued. At this point I am pretty sure it is the small case fan in the back of the NAV unit that is slowly failing. Link to video:


Has anyone else have this issue?

I did a search but was unable to find a write up on how to remove the NAV unit so I can replace that fan. Does anyone know of one?

Thanks in advance--
