05 Camry Leaking Gas

I bought a brand new 05 Camry XLE a week ago. During the past weekend, I
found out the car is leaking gas at the Fuel Rail / Injector. The car is now
at the dealer for repair.

I'm curious how often this type of things (broken new car) happens. Has
anybody else had similar experience? I have a 2000 Sienna and never had any
problems in 5 years.

What can I do if it has a bad thread in the engine block for the fuel
injector? Can I ask them to replace it with another new car? I really don't
want to accept it if it has bad fuel injector thread on the engine block and
they have to somehow patch the bad thread to fix it.

Otherwise it's a great car.

Thanks for your advise in advance.
