if you look at the owners manual it shows that when air directed to the bottom, some comes from the top as well (small arrows top, large on bottom). i too find it very annoying one thing i hate is that the temperature from the top vents seems to be just as hot as the bottom. if the air were a bit cooler it wouldnt be bad. obvioously manually closing the vents solves the issue, but i hate doing that, because i am manually fiddling with the automatic system. agree that it it is not broken - just an awful design. have another vehicle with auto climate, when the cabin reaches set temperature, OUTSIDE air come in to the defroster. ouch, on a cold day it is awful. that system is made by Denso, and this was common for all debso systems around the time. any idea who makes the lexus system? maybe there is a setting to close the top 100% when air directed to the bottom.

I think you are correct Barkat. But this can take a substantial amount of your time and energy and will undoubtably lead to just more of the same. I dealer I go to does a great job. I have been dealing with issues (albeit minor) since maybe 3,000 miles. It is the game of "Wacka Mole", once one thing gets settled another pops up. Unfortunately the dealer is trying to make the best of a flawed product. They actually encourage me to come back if I am unsatisfied. Things do get silenced down for a bit , but within the next 3000 miles another noise rears its head. I know this had been argued back and forth, and don't get me wrong I think its a great looking design, but the fact is (by reading the threads on this very forum) that these late model LEXUS products (at least the interior combination of materials) are poorly selected and assembled. And with this third generation very little has changed in the assembly or factory fixing of TSB items from earlier generations. Its really sad as I think this is the best looking car on the road. are there the same isues on the other lexus models? i wonder if overall the elxus quality is slipping and/or they are chossing cheaper materials. or maybe its just the IS...

i leave the system on auto all the time. i dont get cold air in my face. i get warm air. it is quite annoying. in other cars the upper air is cooler than the lower air. here it seems they are the same. is this normal? to keep at a temperature comfortable for my face, my feet are usually cold.

dial by name: say dial buy name car responds 'dial by name has been chosen, when the display has updated please say the name' you press talk switch it says please say the name you say the name it says the name you just said then it says push off hook switch to dial orsay dial oir something like that ANNOYING

i have a draft lower, near the foot brake. extremely annoying, my right foot freezes alll winter

doesnt bother me at all.

safety feature: while in motion the number doesnt come up. if the number is in your phone book, it will show the name while driving. so basically if yoiu are driving and someone who is not in your phonebook calls you will see nothing agreed its annoying.

there is a TSB for the 350 trhat installs the GS's low brake dust brake pads. ive read elsewhere it does help the brake dust issue.

i remember reading somewhere (not sure where), that its 70% rear and 30% front all the time, and it adjusts additionally as needed. there is a light on the dash that illuminates (looks like a car with skid marks behind it) when it detects wheel slippage. when this happens i assume it is adjusting the front/rear mix.

one thing i think is off about the tranny - when letting off the accelerator the rpm drops some, say 1000 - 1,500 rpm. then it quickly jumps back up a hundred or two hundred. then stays there. any idea why this happends.

ive had a similar experience, but actually i did notice my right foot is OK, but my left is freezing. also seems that the ehat coming out of the face vents is warmer than the foot vents. personally, i like heat to come out only on the feet but this is impossible. in for 5k service i mentioned it to the tech who checked it out and said it was normal. no big surpise there. im hoping a TSB comes out because something is just not right.

i heard that once you update you cant override to use the nav system while driving.

how about wind noise? when the sunroof cover is closed its a lot quieter than when open. is this normal? its not excessive, just much louder with the sunroof shut and cover closed.

My understanding is that the NAV system has not changed at all, and the antenna is still not exposed. The shark fin antenna is for the sat radio, as EVERYONE was complaining about the after-market antenna being installed with the sat option. where is the nav antenna, anyway?
