Last note: changing the tires may impact MPG. Heavier tires can bring down the MPG a tad. Not sure by how much. In our 06 HH, with the heavier SUV tires, the best we can do in normal speed limit gentle driving is 27 MPG per tank. If we slow down below speed limit (on city streets), we can get 28-MPG per tank.

wwest & cdptrap,
 
Thanks for the advice. My '07 HH came with Michelin Energy tires. I wonder if silicon paste or aerodynamic windshield wipers would make noticeable difference though..
 
I'm on paved road 100% and I'm very sensitive to noise. HH is dead quiet at below 40mph but becomes very noisy at highway speeds. I've driven '95 Saab 900, '97Acura Integra, '00Lexus ES300, '99Jeep Cherokee, '06BMW 525, and '07 camry at least 20,000miles each and I must say '07 HH is one of the more noisy after acura and cherokee.
 
I checked Pilot site and it seems Pilot owners think highlanders are quieter. I wonder if Lexus RX400h makes significantly less noise. Someone please tell me no because otherwise I am going to regret for not considering 400h for $4,000 more...

The interesting thing is, aspect of quietness, is the quieter the car is the higher the expectations of the quietness becomes. If the window seals in my '92 LS400 start to dry out I notice it IMMEDIATELY.
 
My '01 911/996 cabin is tight and very quiet so the little bit of wind noise that I get, starts, at about and above 120 MPH is very irritating.
 
At first I thought it was wind noise as the windows "lifted" from their seals at the higher speeds so I used the silicon paste....even quieter overall but high speed noise, seeming wind "whistle", is still there.
 
As sort of a last resort I removed the front and rear windshield wipers. Noise GONE.
 
Turned out it wasn't the rear wiper at all and installing those new EXPENSIVE, $40/pair, Bosch "wing" front wipers eliminated the "noise" altogether.
 
Haven't yet tested at 120 MPH plus but that was only there to get your attention, noise actually started up at about 40-45 MPH.

Greetings:
 
I too have a 2007 HH Limited and noticed pronounced wind noise above 50mph. I've determined the wind noise is coming from either the roof rack cross bars or the rear spoiler. There is a way to remove the cross bars but I am reluctant to do so as I don't want to damage/marr the vehicle. The wind noise from the side windows is minimal as is the engine and road noise. Of course when the ICE is off and in motion, the car is very quiet indeed. I also have the Michelin Energy tires (LX4) which may be why there is very little road noise. Still, I am extremely pleased with the vehicle and getting an average of 28mpg confirms I made a good choice.
 
I wonder if the 2008 Highlander has this same issue as the cross bars are now an option instead of being standard.

If the noise is from the roofrack, try putting both bars together in the rearmost position. I think I've read that is what the Acura MDX people say to do to minimize noise. Try some different positions before removing them.

I'm 6 feet tall and was able to test an '08 - all three rows are just fine. I sat in the first passenger one, moved the back so there was about 3 inches in front of my knees, then did the same to the 2nd row, and the third row ended up with 2/3 inches as well! Plenty of room for 3rd row. Total redesign in that sense over previous Highlander.

I echo this sentiment and HAVE THE EXACT SAME ISSUE!!!!!
The design of this is totally flawed. and now it's going to cost me almost $2000 or not have air conditioner in a brand new car. This is completely unacceptable. Please let me know if any one else has had to replace the condenser in their highlander hybrid. my email address is rhrouse(at)gmail.com.
 
Thanks, r

Just got back from a 3 week trip to Europe, and it started up instantly. Not only that, the hybrid battery was nearly at full charge, so apparently self-discharge is not an issue...
 
As for the gas mileage, I wish people would STOP COMPLAINING ABOUT THIS!! Gas mileage in a hybrid- ANY hybrid - is HIGHLY dependent on driving style. When I drive our HiHy, I get 29-30mpg. When my wife drives it, she gets 25. Same for our Prius... when I drive it, I get 51 typically. When she drives it, she gets 43 or 45. I use pulse and glide, and coast whenever possible. She just drives, typically with the AC on all the time.
 
Even driving with complete disregard for gas mileage, a Highlander Hybrid still gets better gas mileage than the regular one, and pollutes a lot less. If you don't want to put a little effort into maximimizing your gas mileage, buy a Vespa or if you really want to complain about gas mileage, buy a Hummer, but stop complaining, please!
 
Both the Prius and Highlander Hybrid are EXCEPTIONAL vehicles with INCREDIBLY HIGH quality. Save your breah if you want to piss and moan, the vast majority of owners are completely satisfied with their purchases and are completely thrilled with Toyota. I know I am.

This "punctured A/C condensor" problem has been discussed on an RX forum. After striking out trying to contact you directly and at the risk of violating the rules and regs of this terrific forum, here is a link that DOES pertain directly to your comment. Unfortunately there was less than a satisfactory resolution:

I would definitely stop complaining about gas mileage if I got 25. I would be ecstastic with 29-30. 21-22? Not so much...
