Climate Control Issue

Anyone else have issues with their climate control not retaining your last used temperature or mode? My IS 500 will forget what temperature or setting I used before I turned my car off.

Last night, coming home from work I had the temp set at 74 degrees, blowing air on the feet and the windshield. Turn the car off, so inside blah blah. Get in this morning, the temperature is set to low with air blowing in my face. Sucks when it’s in the 20s, and you have cold *** air blowing out.

I asked my guy at the dealership, and he keeps bringing up remote start. I barely use remote start. I certainly haven’t used it in weeks. So it’s not that.

I’ve looked around and seen some posts about sensors or servos…not sure why those would be an issue on a brand new car. What else could it be?

But, it'll revert back once I unlock with my key. Do you use the same key every time?

So I wouldn't be able to tell you which of the two settings fixed it. It's worth nothing that I have the auto function disabled in the headunit and in on the actual climate control toggles. The climate control has a mind of its own in auto mode.

So I think I figured this out. When I go to work, I have a key fob in my work bag with my house keys and such. I also have my smart key card in my wallet in my pocket. At night when I get home from work, I guess the car is recognizing my key fob. The next morning when I go to take my son to school, I just gave the smart key in my wallet.

So, different climate control memories for different keys. I just never thought about it recognizing the fob from my bag instead the smart key in my pocket.

mystery solved, I suppose. In case anyone cares! Lol

But if you have the Smart Key Card in your wallet, why carry one in your bag?
Seems redundant is you don't need the buttons on the fob.

I’m just used to carrying all my keys in my bag with me, I dunno. Never had a smart key before, so never really thought about it. You’re right, it’s a bit redundant. Need keys for my job and house. Didn’t think about the fob.
