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.

09 Highlander Sport V6 Engine Vibrate when cruising at 50mph/1800rpm

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.

You may want to wait a while. I am finding with our 09 HL Sport AWD that the shuttering at low rpms is subsiding. However, ours mostly shutters when going up hills between 30 and 50 mph at very low rpms. Only noticed it once or twice on flat grade. It will still do this on occasions but has greatly reduced. We now have 1400 miles on our HL. It seems by previous posts that it will go away completely when the vehicle logs about 4k -5k miles. So I am no longer concerned because ours has already gotten significantly better with only 1400 miles.
Someone here had there transmission fluid changed twice and said that seemed to help but I am convinced at this point that it has to do with the computer learning curve.
