We've just had our first few autumn days where a heavy dew settles on the car when the temperature drops in the evenings. When I left the restaurant last night, the moisture was so thick on the outside of the glass I couldn't see out the rear window. I turned on the rear defogger and it was soooo slow. It took five minutes before you could start to see the wire lines in the glass appear and 20 minutes to clear. Is anyone else seeing this? None of my other Lexus' have been this slow to clear the rear window.

We've been getting some cold weather up here of late, so I'll certainly test this out over the next few days (my car is always parked indoors at home and work, so whenever I get a chance to have it out for a long period of time)

Thanks We haven't had frost yet so I'll be curious if frost clears any faster than dew.

It does works slow, on my GS it would usually clear once I dropped off my brother at school which is a 30 min drive. So pretty much the first 10min I drive blind.

Slow as molasses

Had 2015 is 350 .... quick and normal...

The rc sucks... i was going to bring in for 5k service and complain. I thiught it was broken... why is it so bad???

I think that's normal as mine takes forever to defrost as well. By the time I reach work 20 minutes away it is still barely clearing the lines. I just got to use to driving without using the rear windows as my tint is super dark.

Glad to hear it wasn't just my car. I guess I'll bring it up at the 5k mile service, but sounds like they won't know it's a problem. Stinks having to learn to live with it. I guess I'll store a squeegee in the trunk to clear the moisture and light frost before driving off.
