You didn't buy a phone from Google, you bought it from HTC (I assume this is the Nexus One, the same as I have) with heavy Google branding on it. If you want to get hardware support, you'll go through HTC directly. Learn your lesson that HTC has shitty component quality and never buy from them again. Google just makes the software, which works fine. The hardware in the Nexus One is another story...
As soon as some good dual core phones ship this year, I'm jumping ship off the HTC boat.
google posted several videos bragging how they had control on the device creation. (ironically, there was even one devoted to quality control of the device)
And yes, the other reply is correct. most of them are software issues.
