around 30-35% are defective
I don't doubt that a mechanic would say that, but c'mon--that's absurd! As a mechanic he probably only sees problemed cars, so I think he has a bit of an adverse sample selection bias.
The problems usually will shows up in the first couple of years...
So, in the first 2-4 years a full third of GMs engines will fail? Yeah...I'd take that percentage with a boatload of salt.

I traded my 06 STS for the new CTS. I found at first the seats were short for my longer legs, I'm 6'2". It was a serious consideration before buying the car. So, I would get in and out of each car a number of times and spent quite some time just sitting in it. What I figure is that with every car there are compromises.
I've now driven my CTS on a 450 mile trip, one way. My body has adjusted to the difference in seats, and I find the car quite comfortable on longer trips. I also realized that the entertainment I have with my CTS far outweighs the seat length.
My AWD has every option. I had a blast in the Idyllwild snow a couple of weeks ago, and felt very secure in the worst of weather which confirmed my suspicion that this was the best decision I made.
Take the time, drive the BMW and Audi. The seats are a little better, but try to figure out how to turn the radio off without having to read a book.....
Good Luck!

"around 30-35% are defective"
Ridiculous assertion. No manufacturer of any product with a defect rate like that could survive in today's competitive environment.

casting "defects" are defined.
All castings have defects, but only a very few slip through the inspection & classification processes meant to eliminate the ones that will actually fail in service. It's not too far-fetched to posit that 30-35% of automotive castings have surface indications of one size or another. So long as the defects aren't linear & beyond the length that experience has shown could allow them to grow into something significant, it's no harm/no foul.
Something like what the meaning of "is" is. There are defects and then there are rejectable defects.

I highly doubt 1/3 of engines being rolled off the assembly line are defective. That is a gross exaggeration. With every manufacturer, there are manufacturing issues, some more, some less. I agree, no way a company can survive by selling 1/3 crappy engines. I'm sure the number of bad engines are more like 1%, if not less. Unless the engines are flawed, which I doubt.

Engine update Friday Feb 1st. Basically I still don't know anything.They have the engine torn apart and can see where the dye/water is getting in one of the cylinders. Problem is they don't know how it is getting there. No visible cracks in the head, block, or head gasket. They have the head at the machine shop now checking it out, but the service manager told me he doubts they will find anything. The dye should have shown a crack if there was one. His best guess is that the block casting is porus letting the water in that way. He is working with Cadillac technical services, trying to get authorization for a new engine, what I wanted in the first place. It's been in the shop for 8 days this time and he admitted Caddy probably wouldn't make a decision till Monday at the earliest. That means with shipping time for hopefuly the new engine, and disassembly, reassembly and installation, I am looking at it being in the shop for another week to week and a half. That probably puts me up to about 26 days or so in the shop since the first of the year. Oh, I forgot!! Caddy offered me a free oil change. At least this time the rental isn't a Cobalt, the Grand Prix while no Caddy is certainly much better than a Cobalt. With rental car fees, all the problems the first time in the shop, and now the engine, I can take solace that GM hasn't made a penny on this vehicle. Too bad they just don't get me a new one, or money back, and take this lemon to Detroit to study how NOT to build a car.

"The first time, Lexus gave him a new car. The second time, they gave him his money back and he went and bought an Acura TL. That's the legendary Lexus customer service and it's why Lexus has a loyal customer base."
Apparently not too loyal, since he went out and bought an Acura.

Lexus did not want to sell him another car after declaring two lemons. It was like, take your refund and go away!

Alot of these castings that have defects that are not visible with the human eye. There is a series of NDT non destructive tests that can be done on these parts to find fatal cracks and imperfections. Different types of tests are Ultrasonic, Magnetic Particle and Liquid Penetrant which gm favors to find the cracks/leaks after a problem crops up. GM uses a liquid penetrant with a flourescent light to excite the particles which shows where exactly the leak is.
If GM were to do these tests on the engines before assembly, the price of your car would GO UP in price because these procedures are very time and money consuming. Usually these type of tests are done on race car engines and Aircraft parts ,sheet metal and engine turbine components . Parts like this if they fail will have disastrous results.
So some types of defects are OK and some reject able defects will get by GM . They can't and won't do these NDT's tests as they are too costly and time consuming so we as consumers get a mass produced product.
