Yes, I get the loud resonance at times. All this makes me sick. I have not made the first payment yet.

There seems to be a few complaints of odd noise that is originating from the new variable displacement A/C compressor. Turn off the A/C to see if your "noise" is reduced or alleviated.

2-3 minutes idling is just wasting gas.Should idle at most 30 secs. Car will warm up faster when driven gently. Putting tranny into reverse when in high idle will be jerkier in most cars. I try to avoid reverse startoff in high idle if possible when parking.

Good advice by typesix. I concur.
 
Also, I've really paid attention while doing my cold weather start ups (+1 degree this AM). I have no steering wheel vibration and no jerkiness. I guess I'm luck so far (10,800 miles).
 
I hope Toyota will be able to rsolve these problems for those who have them. Best of luck!

Don't you feel that the engine is considerably noiser during the first several minutes after cold starting? To me it almost sounds like a 4-cylinder (ok, maybe I'm exagerating just a bit). Anyway, I'd be curious to see how much quieter an RX350 is inside.

Yes, this V-6 is noisier than my first two HLs, especially at start-up. However, both of them ('01 and '02) had the 3.0L V-6.

Now if we had a 2.0 that would really, really be quiet.(smile) With the Highlander apparently going to 3.5L in the 2008 the noise level should get even higher, right?

From what I've read, the Lexus RX350 which uses the same 3.5L engine is actually quieter and more refined than the RX330 was. I think that in part,it is a function of how much sound insulation they put in. The insulation pad on the firewall (inside the engine compartment) in my Highlander is really not that thick. The pad in my old ES300 was thicker. The vibration could also be a function of the motor mounts which I believe are active control. Keep in mind that some of this might be marketing strategy meaning that Toyota/Lexus might not want to make the HL too quite because it so that the RX still has something to more to offer than the Highlander IMO. My guess is that the new Highlander will be quieter but still not as quiet as the RX350.

No, I'm afraid not. I'm actually a Software Engineer.
