If you are talking about failure, it is not common. if it you are talking about noise, it is common. I have experienced it in every other 460 I drove/owned.

I always wondered about the commonality of reported problems on user forums. While there is no sure-fire way to know for sure, there is some estimating that can be done. Of course, just bear in mind that any data you pull will in now way will be representative, but it might give you a ballpark, well, more like city park.
1. Search for the problem and see how many different users have reported it here.
2. Determine, the best you can over that same span of reported problems, the amount of overall users or owners.
3. Ratio and determine the percentage of those who experienced it versus those that have not.
The caveat to all of this is how many people here have not reported it? We assume all users here would indicate that they experienced it, but that isn't always the case. How many people out there that have the problem but aren't even registered here. A lot I'm sure. Conversely, how many users out there have not reported and aren't registered here? Even more probably. The other issue is mileage and age of vehicle per user. Like me, I would skew the numbers as my car is new, but you could technically count me as a user that has not reported it.
In any case, just an interesting thought. Good luck and for the record, I have not experienced it.

Mine was replaced at 25,000 miles. Also my ML amp at the same time. Looking at my records I figure with the Valve recall and front window glass upgrades etc. Lexus paid out at least 10 to 12k in claims under the original warranty on this 2007. When a new model came out of the box like this me and the rest of the techs would not be happy to say the least. Volvo did this to us a couple times. At least Lexus stepped up and fixed them. Mercedes, Audi, VW and BMW usually cant even fix them or just strokes you till you give up. How any of those companies are still in business is really a surprise to me.

I think the noise is just endemic of the actuator and mutually-exclusive of any potential failure. Well, I guess it depends on the noise.
The noise we are talking about is a "clicking" upon the depression of the brake pedal. Turn your radio off, go five MPH then press the brake and let us know if you hear it. That noise, we presume, is just a natural part of the car's braking system. We have theories on what it may be, but no one knows for sure. It's very subtle and can be easily missed, but once you hear it you will always hear it lol, unless you drown it out with the radio. It becomes transparent at higher speeds due to road noise, that's how low it is for me at least.
If it's a different noise, then no idea.

Again, you can always ignore the noise, turn the radio on or whatever... If this is acceptable to you for the investment you made, then as long you don't see lights in the dash then you are probably ok.
