My brother-in-law had to have a new transmission in an '87 Corolla when it was only a couple of months old. He ended up putting over 200,000 miles on the car before getting rid of it. Didn't have an impact on the engine in any way.

At 1000 miles, I am going in to service next week. 2007 Highlander Sport, V6 FWD
 
Engine Vibration transmitted through steering wheel, Most pronounced at 1800-2000 RPM, Run vehicle up to 1800-2000 rpm and feather the throttle and you will feel much vibration in wheel, floor and gas pedal
 
High RPM Cold Start, During cold start, engine idles at 1900 RPM, You get a nice jolt when putting car in gear
 
Brakes too sensitive, Feels like brakes are out of adjustment, Far too much front braking, Lot’s of play in pedal before harsh brake engagement
 
Transmission, Car is never in correct gear. Example: At 1000 RPM, 20 MPH, car is in 5th gear? Taking foot off gas does not slow down vehicle, Will maintain speed, Car surges forward as car is shifing up to 5th gear during slow city driving. Why won’t this thing stay in 4th? Feeling like getting pushed from behind. Car is still down shifting from 4th, 3rd, to 2nd to first at 3 mph as I pull in garage. Feel surges. Can you change the shifting characteristics of this transmission? Less shifting!

High RPM is usual in cold starts. You should be waiting the two or three minutes needed to reach temp, and idle down, before slamming it into reverse.

When idling, I get a 'boominess' or resonance type of sound that almost sounds like a loud exhaust but if I open the door and stick my head under the car, it sound fine. Does your's sound like this? Is this maybe just a engine vibration that is being transmitted into the cabin? Maybe the motor mounts aren't doing their job. I still don't get why if this is the same engine as the old V6 Camry and ES330, it is so loud. I can believe that the ES330 has more sound insulation on the firewall but not the Camry. I will try to get back to the dealer this weekend to start another new Highlander and see if it is the same. Is is possible that they messed with the air/fuel mixture or timing in the latest software and that is adding to the noise/vibration?

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.
