Wow. I parked the car on the top level of a parking garage yesterday and when I returned, the car was obviously hot as it was in the sun, but damn! I went to use the touch pad to change from AM to XM and boy does that touch pad get hot. I am talking so hot you don't want to touch it!

I might start putting an index card or something over it if I have to park in a hot spot in the future. Just a heads up here - anyone else find this out the hard way?

 

Sorry to hijack your thread, but how does the RDX air conditioner handle hot weather? Does it cool in a short amount of time? Thanks.

 

 

 

what's it matter to you?
I think it's a very valid question pertaining to heat, which this thread is based off on...
I'm sure interested parties are wanting to know as well.

 

We have around 90-100 degrees here in Michigan. What i have experienced from my 19 RDX is it does not pick up cool air fast when inside temperature is high. It takes about 10 mins to get the cool level i wanted.

 

I find the 19 RDX cools as expected. It is always going to take some time to cool off a car that has been sitting in the heat of the summer sun. The amount of air that needs to be cooled inside an SUV takes time to be exchanged with chilled air. Add in the hot surfaces giving off heat.

I typically park in a parking garage at work so when I get in the RSX to drive home, the AC works great.

 

Exactly...and no vehicle I know of can do an "instant" cool down esp. if the temps inside are well above 100 deg. What does help, is putting a sunshade in the front window, and not parking facing the sun...east or west...IF possible.
And, cracking the front or rear glass about a 1/2 inch to let out that built up heat. I know...it could rain...and IF it's expected then I don't crack the windows.

You can also place a smaller towel over the upper console area...if you are parking in the structure everyday and have to deal with this issue a lot.

 

RSX? I think I someone may have altered the time space continuum...

 

He takes his RDX to work and then the RSX home.

 

 

Perhaps I should have asked, "What is the capacity in tons and how many BTU's will it remove in an hour".

 

What, me spell-check and proof read?? Puh-lease!

 

LOL....very good MarineOne! No, that would have really put them in to a head spin, and they may never have recovered!

 

Wow, I don't mind the hijack, but this is a REAL hijack! LOL

No matter. I just wanted to see if anyone else ran into the hotplate touchpad yet.

Anyway, to follow the turn of the thread, I have noticed that it takes a few minutes longer for this RDX to cool down than my former '17 RDX did. Not sure why or if it's just an illusion, but it did seem that it was a longer cool down than I expected.

 

 

The hotter they get, the better they sear!

 

My wife says.."yes they do." She drives it to work every day, and it's been in the 90's everyday for a long time.

 

Since we're on the topic of AC, how about some comments about how well the AC can keep the car cool on a hot sunny day, with the pano roof shade open vs closed, etc. I was reading a review about the Mazda CX5 where the reviewer took a trip from San Diego to the mountains and said the the AC seemed to struggle and couldn't keep the car cool to his liking and the weather was sunny but not humid.

 

In this heat we keep the sun shade closed and it keeps out the heat quite well. The air works fine. Get's cold, esp. if you use the "recirculation" button, so you are constantly using the air inside the cabin to cool more vs using outside
hot air. Esp. when it's in the 90's and above. Also, to help out, when really hot out, I open the vents on the back side of the console so air can flow to the back areas faster. Don't have to do that just because you might have
passengers back there. Just quickens the cool down and cooling process. Bump the fan up higher until it gets cooled down....then regulate from there.

The Mazda has no power to begin with, and maybe the RPM's that the compressor pulley is turning is not up to the task?? I'm not sure. But, comparing the Mazda to this Acura or anything else is like apples to oranges when
doing a comparison like this. IMHO

 

 

I agree. And I've owned 18 Hondas and Acuras....they don't overheat, and the air works great. One of the first things I noticed in hot weather when I first owned Hondas.....idling in hot weather with the air cond. on, the temp. gauges
in those Hondas hardly moved a fraction. Those electric fans kick on and stay on when Idling....and it kept the radiator from getting hotter. Now most all new vehicles have electric fans, that are temp controlled. Not sure though
IF ALL vehicles run as cool as Honda Motor Corp. vehicles, but, I'm sure many do.

 

I dont think its a RPM issue, but rather, the components, condenser, evaporator, or compressor are probably undersized, or heck, maybe the reviewer didnt have the recirc on. I cant remember where I read that review. I know that the CX5 is not really in the same class as the RDX but the interior is kind of nice and fully loaded, with HUD, and all driving aids, comes in about 35k. There's talk of a turbo 4 gas or turbo 4 diesel next year.

 

 

It has been over 100 the last few days here in Kansas City and I find that it cools down as expected. Even better when I can start the car 10 minutes early from my office on the second floor before I leave work...
