You have just discovered what has irritated thousands of Lexus owners since 2007. The Nav system that only works right when the car stops. There is only one place that I know if that has figured out how to get around the lock out. Lexus will not help you with this.

As for you rattle on the roof, its actually coming from under the car. The car design makes it seem like the noise is from the roof rack, but it is not. This cause is also well documented, just ask your service advisor about it. 15 minutes at the dealership and the noise will stop.

Good luck!

We just got back from a 350 mile ride round trip with the new Lexus. We averaged about 20 or so mpg. I am sure the mpg will get better as the car gets broken in.

There are two things I noticed which is probably known by owners already: (1) You can not change your destination on the nav if the car is moving. (2) The Contact list on the phone is not activated. Okay perhaps the human engineering people at Lexus wants us not to tinker with those when driving the car for our own safety. The vocal command works but it has a hard time understanding my voice commands when the car is in motion. Its really really irritating. Perhaps somebody has figured out how to defeat this?

There is also a rattle when the car hits a bump on the road. It sounds like its coming from the top of the car. I checked for anything loose but can not find any. Anybody has a similar problem? I removed the cargo cover but that did not help.

I was pleasantly surprise when the wiper turn on by itself (auto rain detection) and started changing the frequency of the wipe depending on the intensity of the drizzle.

Overall I am satisfied with the performance of the Lexus. Its smooth, quiet and confortable ride.
