hi guys. i got exactly the same problem with my 2009 V6 4WD Sport which i bougt it last week. it now has 200miles on it and still does the vibration thing. also it has the following problem.
while drining in "D" position, if i let go of the gas, the transmission downshifs quickly. as a result, the car slows down very quickly as appossed to keeping rolloing that you would expect. if i switch to "S" position, the slow down would be much more natural.
My dealer says its a normal thing while the vehicle is breaking in. but i just wanted to make sure if anyone else have the same issue and if this is related to the 'vibration' problem also.

my dealer said the same, and a number of others here have had the same problem, mine cleared up as did others, but I did notice it slightly once again last night but it occurred at 1100rpm which was very low engine speed but previously it occurred at 1500 rpm, I genuinely believer this is a running in issue or computer learning issue but I'm waiting a little longer to record a verdict I currently have about 850 miles on mine and the effect is a LOT less and harder to reproduce even when you are trying to provoke it. Because the car is so quite and smooth, you do notice it compared to something less refined. I also noticed that shifting into sport mode altered the change up points and the problem went away

I did the same thing stevied5! I was thinking the same thing (maybe I got a lemon../maybe this is why I got a great price on this..) and I did the same thing - trying to figure out if it's the road on every vibration or noise. Alas, it has calmed quite down and is such a pleasure to drive. Now I look at it with pure excitement as opposed to that same disdain feeling I had before. I love the HL now.

Until the battery fails, is disconnected, or replaced, and the engine/transaxle firmware reverts to the factory default parameters. Some engineer has picked a default parameter on the "wrong" side of conservative, too far in favor of FE apparently.

Well, I disconnected the battery at about 3,500 miles when I installed my Toyota tow hitch (you have to install a fuse and other electric components). It hasn't reared it's face after that, so I'm pretty sure that isn't an issue.

Hi all, I just bought a 09 Highlander Sport V6 that vibrates when cruising at 50mph and at under 2000rpm. Should I wait until I hit 1000 miles before bringing it in for check up? I have put 500 miles on it so far.
