Climate Control Questions

2nd trip to dealer; this time they say they found a ‘smaller than a pin hole’ leak in the refrigerant line and that there was no juice left. New line will take 2 weeks to arrive. Said they only recently knew to look for it as they found it on another one a few weeks ago. We shall see…
I cant see how a leak in refrigerant would cause the issues we have discussed here. weak air flow, too hot on set temps but still blowing cold on low.
 
My A/C didn’t kick on till I set the temp to “Lo”. Not 61 but “Lo”. This isn’t right. Never had this issue in my previous cars with auto hvac unit. I submitted my concerns through Toyota Brand Engagement.

Good afternoon. I received a call from the Toyota Brand Engagement representative and she told me basically that they are looking into the problem. they had the report from the tech. that indicated that there is a calibration discrepancy in all the vehicles he compared while checking my SUV.
I think that if we keep complaining and registering our dissatisfaction with Toyota because of this problem at some point Toyota will find a solution.

It gives each of us a little bit of hope.. Thank you for sharing

I think we should also add to these complaints that the air flow is very weak on 60+ too. I feel like that is under discussed on this thread. Or maybe I'm the only one that has a problem with it idk.
 
Well I received a response from Toyota Brand Engagement.

BLUF: They said take the vehicle in and then we'll talk to you. So unless you've wasted yours and the dealerships time with the HVAC being a pain in the ***.... Toyota has nothing to say

I also filed my complaint with Toyota and the Toyota Brand Engagement team reached out and told me to take it to the dealership. Funny enough, I have taken it twice to two different Toyota dealerships in two different major cities and got the exact same response from the service department.

"If the AC is working fine, the technician won't look at it"

I mentioned this to the Toyota Brand Engagement person that reached out and they told me to take it to a authorized Toyota dealer.

I told them I am afraid they won't be able to replicate the issue right now in TX weather. It only happens when its below 35 degrees outside.

Toyota of Irving here in the DFW area looked at mine and agreed with my complaints they just couldn't do anything about it besides call the corporate tech that comes and says its fine. BTW i posted a YT video of the AC doing this in 53 degrees here in TX. I think your estimate of 35 degrees is a little low. Just tell Toyota brand engagement that you did in fact bring it into a dealer even if you haven't or they brushed you off. I did that before I even took mine to the dealer. just say they cant fix it or something but agree there's an issue.
 
Received similar feedback as others from Brand Engagement:

"
Thank you for contacting the Toyota Brand Engagement Center.

I updated the case with asking them to reach out to my dealer so Brand Engagement remains in the communication channel
 
I received another call from the Toyota Brand Engagement representative and she said basically this:
"we know that the problem is there. we know that the Toyota master tech said that there is a problem but there are not sufficient complaints to warrant a Service Bulletin to be issued." She said that she was sorry this was happening to many of us but the brand is not doing anything about it because only a few owners are complaining.
I will be getting rid of this vehicle and get something else.
 
After reading all the posts on this subject I became worried because as explained in my previous post my car showed the same symptoms.
This morning I have focused in the Toyota A/C. I have placed a thermometer inside the car suspended from the sunroof about one foot down. With an infrared thermometer I measured the temperature on the front center AC out. I have tested diferent settings of the climate screen controls. After some trial and error I have found a setting that really makes the difference. The system works properly. The attached images shows the settings. The button in the dashboard in AUTO mode. The car was parked on a sunny place inside temperature was high. Immediately after start the engine a powerful air current get out from air outlets. The temperature of this air was 54°F. I have tested the car off road at low speed on road at 60 mph and stoped and the feeling inside has fully changed. Moreover the AC indicator has turned on automatically. The only thing that for me is not fully OK is that I need to adjust to 66°F the AC setting to obtain a confortable temperature

Don’t Have this option on my 2024 first edition. Or at least it’s different words
 
I’m having this issue too
In cold weather can’t get a luke warm air just hot hot air

New 2025
 
Yeah, same isse as last winter. It was 55 outside but I wanted to blow cold air. It wouldn't do it at all unless I set it to LO. Even at 60, it would blow warm air. Working as intended I supposed. Their computer knows better than we do.

It’s just conditioning you for the robot takeover
 
I'm happy to say that I no longer have this problem. someone else has it. because of TOYOTA's inability to solve such a simple (in my opinion) nuisance, I decided to get rid of the Land Cruiser at a loss. I purchased a Land Rover Defender 110 P400 X Dynamic. It has a Turbo Charged and Supercharged 6 cylinder engine and my wife has had one since 2022 that has been completely trouble free. takes all the abuse and no complaints. oil change and keeps going. 20+mpg (better than what I was getting with the "Hybrid Land Cruiser") and the air conditioner works as it is supposed. oh, and the Remote and Guardian subscription is less than 7 dollars per months. (not to mention that it actually works)
 
I knew this thread would come back up when a cold front came through. like clockwork. Hopefully with more people pissed off about it this winter than last so they actually do something about it.

Don't hold your breath. Toyota took my vehicle (by that I mean the Tech from Toyota. not the dealer's Tech) He tested the Land Cruiser and compared to several new and used (in service in the lot) and found the same problem in all of them. noted the problem and recommended nothing be done because it did not affect the performance or safety of the vehicle. I have the documentation that states that he found the same discrepancy in all the vehicles and because it is not affecting the safety or performance they basically don't care. the Brand engagement representative called me and in different words told me to "F**ck off and get over it" basically said there is nothing I can do to make them fix it and they are not going to fix it. I did the only thing I can do as a consumer. Got rid of the product I will not be buying another Toyota (or Lexus) in the near future. by the way, I really liked the Land Cruiser when I had it.
 
I am doing some research on mechanical vs electronic variable displacement compressors which control the amount of refrigerant that goes through the AC system. I cant figure out why the mechanical generally feels better for us but I think most if not all Toyota and Lexus vehicles have electronic nowadays even if they aren't hybrid. You can tell this under the hood because there is no belts Infront of the engine powering things like an alternator and displacement compressor. my hypothesis is that for some reason, electronic displacement compressors tend to either open all the way or close all the way. this could potentially be caused by bad quality or bad location sensors that detect the temps and then tell that compressor how much to open or close the flow of refrigerant combined with hot engine air resulting in a set temperature we set in the cabin.

Looks like all recent Toyotas have a similar design and there are people complaining about it across many different models. Those of you who have always had toyota or lexus might not notice just because this is how its always been idk.

that just my amateur google professional opinion.
Our 2021 Highlander Hybrid has the electronic beltless compressor, and the system works flawlessly. It also has overhead vents and rear control as in the LC. So, not a universal issue with the type of HVAC system.
