Well, had my first real chance to use the AC in my Sonata yesterday.
The temps were in the upper 80s with reasonably high humidity (I don't
know what it was, but it felt sticky yesterday in northern PA).
I'd say the AC performance is consistent with the heater performance in
the winter, which is marginal. I ran the AC for nearly 40 minutes
straight and never could take the temp control below the coolest
setting. And I hard to run the fan on speed 2 most of the time to keep
it moderately cool. Compared to my Chrysler minivan and Chevy truck,
this is weak performance. Both will cool the vehicles nicely within 15
minutes with the fans set on their low setting. And after about 15
minutes (I'm talking a similar upper 80s day, not 100 or something
extreme like that), I have to start moving the temperature lever up off
the stop to keep from getting too cold.
So, I still think that Hyundai needs to consider beefing up the HVAC
system in the G6 Sonata. I can't imagine driving across Nevada with
temps above 110 as I did last summer in a Chrylser T&C rental. The van
kept us nicely cool on low fan speed and the coolest temp setting. I
don't think the Hyundai would. Maybe with the fan speed on 4, but that
is pretty loud and would get tiresome on a long trip.
What have others experienced with their 2006 Sonata AC?
