Heated Seats and Steering Wheel not that Warm
#256
Good to know about this fix. I’ll check next time I’m scheduled in for a service. 5 years later and they still are unable to fix my 6-5 downshift issue where 80% of the time when I slow down or brake the gear change from 6 to 5 slams the gears when I’m in sport mode. Also they haven’t been able to resolve my torque steer. Our old 2011 awd ltd sienna’s awd system was far superior than my rx’s.

Yes 9 & 3 are normal and I hate it coming from a car that had the entire steering wheel heated 10 years earlier…. Heated seats are weird but here is the answer if they are not heating or cooling properly. Check to make sure they are not set on Auto Mode. If they are they will heat according to the outside temp and your heater temp setting in the car…. Hope this helps.
Lexus will not over heat a seat. They are safety oriented. The other reason why they heat the 9 & 3 positions is to help keep your hands in the proper driving position. I don’t buy that though. What about summer driving… I think they were too cheap to make the entire wheel heated.

It is normal for this generation RX. In the current generation ES they moved to a new wheel and the entire wheel is now heated. I would “expect” them to apply the same improvement to the next Gen RX. As for the seats, I haven’t paid that much attention to them, but they get warm and take the chill off which is all I need or expect. This is one of those features that will carry different expectations - certainly dependent on weather conditions where the vehicle is being driven.

My 2016 450h has heated seats & I think they are just right for the climate where I live, where it is cool at night & early morning. Perhaps they would not perform well in a very cold climate, as I have never driven it anywhere like that. I was not aware of them being connected to the outside temperature when in auto mode, but it makes complete sense - thanks for that tidbit of info!

Update December 18th 2021.
Regarding the RX-450 HL (hybrid)
I took my Suv in to get a gas warrenty issue fixed and Lexus noticed an note about the heated seats.
This is the 3rd Lexus dealer I took it to about this.
This notice is new and it took them 5 hours and a separate visit but they fixed the seats.
Now according to my wife. The seats weren’t burning hot like the 2021 hybrid ux and es (as we tested in separate loaner vehicle trial runs)
However since the fix there is significantly more heat than prior to the fix.
All vehicles were hybrid models. Just the 2018 they under powered the heated seats.
There is an internal setting under maintenance that allows me to increase the heat temp with. Since this just happened last week I am yet to max that setting out to get that seat to Toasty buns.
However my wife is pleased with the difference from the fix.
Happy Spouse Happy house.

Get the A/C amp replaced!
+1 on replacing the A/C amplifier unit. My dealer just diagnosed this on our '18 RX350; apparently this is a known cause of poor seat heating.
I was not able to find the relevant TSB, and they did not cite the TSB number. It must be new(-ish).
I will try and report back once the amp has been swapped.

"Not only the 2018 had under-performing heated seats, mine is a 2017 and was failing miserably in that dept.
The internal setting, alas, doesn't achieve what we want, at Max setting it keeps the seat heater on for longer. The ONLY way is to have the dealer change the heaters, in my case THAT made a huge difference."

Thanks for the clarification.
shoot, sounds like I should have had that replaced under warranty. Factory expired a few weeks back. Debating the Dealers extended house brand one. But that's another topic
