Air Conditioner

Mine is fine...

 

Just drove to Vegas and we hit 105% without any air conditioning issues. Worked perfectly, even at 140 mph.

 

YIKES!

 

Mine blew hot air due to a leaky seal which caused all fluid to be lost at 1000 miles.

Its fixed now and is "just OK" at 95+ in Florida. I admit I like my cars ice cold in hot weather and keep it at the 62 min.. My other cars, 575, 430 and even my 512 seem to blow much iceier air. I won't talk about the 328.

The dealer says all is working as designed. "Just OK".

 

Wow, sounds like a fun drive to Vegas.

 

South Australia can be hotter than Texas and I don't recall any problems last summer. The fan speed dropping doesn't sound right to me.

 

we haven't had enough hot weather here to check, but there have been a couple of occasions where I have taken it out of "auto" mode by bumping up the fan speed manually. If you do that then the fan speed should certainly not decrease on its own.

What I have noticed is that the cockpit does get very warm after you shut down (heat soak), especially compared to my M3. This is probably due to the mid engine configuration, so maybe the air con system has to get rid of more heat than other cars.

 

It has been about a 100 degrees here in the midwest with heat indexes from 110 to 120 and my A/C seemed to be working okay for the last heat wave but the very last time I was driving the 458 it did do something weird. The A/C stopped blowing cool air for a about 30 seconds, I think I hit the A/C button a couple of times and then it started blowing cool air again and seemed okay for the rest of the drive.

Unfortunately now the 458 is sitting with a blown fuse so I can't get it started and drive it, so there is no way to tell if that A/C episode was an aberation or whether there is something really wrong with the A/C. I guess I will have the dealer check that while they are replacing the fuse.

 

Mine works good, but on the hottest days I have to run the fan on high, which is lounder than I wish. I have a black dash and with the angle of the windshield, I guess that is no suprise.

 

These cars have a lot of glass area which has a direct impact on AC capabilities. Had an Acura dealer tell me that auto AC has reached its technological limits. It just can't keep up with all the glass some cars have and the resultant solar heating. Tints help a little, but just look at the size of the front window.

 

As I said above, the 458 AC is just OK but not great. I have cars where you could hang meat inside with an icy blast from the AC, not so in the 458.

 

Any of your cars have the thermo insulating windscreen? I was told that helps in very hot weather.

 

Check into Nano-tint as it's pretty much clear but blocks all UV-A and UV-B rays. I have the Side windows and windshield done...I'm in Florida and obviously it gets hot as heck here and my ac pretty much freezes me out of the car!
