So, to comment on a couple of these posts - just my opinion.
Winter driving - I agree that the vehicle is OK in snow with the right equipment. However, I have owned 2 Toyota 4Runners, a GMC Yukon, an Acura AWD Sedan, and now this car. This is the first car where I have needed dedicated snow tires. Living in the Pacific NW, dedicated snow tires are not that common on the wetter side of the state. I honestly think it is the Hancook Ventus tires. The 255/50R 20 is a really large tire, almost impossible to get a winter tire in that size, had to buy wheels and tires to get through the season. Of course, we actually had a winter season here, so that is probably why I had issues. But, with that said, I have done plenty of winter driving with past vehicles on all season tires with no issues. Actually, I own a Chev P/U with Goodyear Wranglers and it does absolutely fine in the snow. Of course, it is a 4x4 not AWD...
Seats - maybe there is a difference in the different models. I have the Limited and it does have the massage feature. I actually think this is the problem, if you could adjust the bottom area I could adjust the area where my tailbone sticks into the seat, this might help. I have used this feature a lot lately just to get through a couple trips, without it I'm not sure what I would have done. Maybe the Platinum has a better seat, I will look, maybe I can swap seats. However, I have read many reviews of people that don't find the seats comfortable so I know I am not alone.
Engine issues - mine has the V6. It has plenty of power although I have previously mentioned the issues I have experienced with the transmission. My only complaint is that the fuel tank is too small. I get a consistent 19-20 mpg, but find that I am always headed to a gas station. Why do they put such a small gas tank in an SUV? 18 gallons, the Toyota has a 23 gallon. A few gallons makes a big difference, in this case probably about 100 miles. I won't have the vehicle long enough to worry about service and repairs so the posts about high mileage service doesn't apply to me, it will be gone when it is out of warranty or sooner if possible.
With all that said, I do like the car. I see them everywhere. I keep thinking I'm going to hobble over to people in parking lots and ask them about their seats... That might be weird...
