Prelude222

2013 GS350 with 88k. I have the cold weather package, since I live in upstate New york. The problem is even when the car comes up to temperature, air coming out is never really that hot. My 04 Honda pilot he is way hotter than this. Are they just like this?

Take it off of auto and run it manuallly. Set the auto climate system temp to max and direct all air flow to floor vents. How does it feel then? Your old Honda has a manual climate system, I'm guessing. Your Lexus is trying to make the interior temp to whatever you have it set to, without being noticeable, IE not continually blowing red hot air to your feet like a non-automatic climate system would. I think it is called climate concierge.

I have it set to manual HI. Its just not very hot. The damn heated wheel is though lol

Mine takes awhile to warm the car but unlike my previous cars it never blows (really) hot even on high.

What does the coolant temp guage look like when driving? Any codes? Maybe the thermostat is getting stuck

Right below half, normal

Same. I've never been able to get this car to blast hot air like an inferno. It's more of a gradual heating.

Pretty sure that's climate concierge at work. Just like the auto seat warmers start on high and get lower as the cabin warms up. Also OP, do you have S-flow turned on? I don't like it in Texas summers. I think its better to cool off the entire cabin in extreme summer heat.
Just the opposite, you may not like that heater is not heating the entire car cabin in below zero temps.

Woah now, in Florida, I don’t even run the heater so I don’t know if it is hot or not. When it gets below 60, I put the steering wheel and seat heater on, and it feels fine to drive around. I actually like the steering wheel heater, though I know people have complained that does not get very hot anyway. Course I am not wearing gloves and a heavy coat either. Guess if it doesn’t blow hot enough for you, dress in more layers…….

Prelude222

LOL someone in Florida telling someone to just dress in more layers. You're the one who puts a steering wheel heater on when it's 60 out LOL

Definitely don't think its normal - once my '13 is warmed up, the heat can be stifling at its highest setting. Low coolant, servo motors gone bad, and maybe even the climate controls set to Eco mode can impact the heat. On my previous 2GS, the heater core was going bad but I doubt that is the case for you.

I'd take it in for someone to look at. In the meantime, here are some threads with suggestions you can try beforehand:
