Interesting column in the latest (June 2015) Road & Track...

"Strange Connections: When Cars Get Complicated Weird Things Happen" by Jason Camissa

...relating problems with the BMW twin-turbo 'N63' V8 engine including "timing chains that stretch and snap, leaking crankcase and fuel lines and malfunctioning fuel injectors, mass airflow sensors and vacuum pumps".

And then there's "BMW is also quietly dropping the V8's oil service interval from 15,000 to 10,000 miles. Not because of oil-life concerns but to smokescreen the N63's appetite for motor oil. By shortening the time between oil changes (and sneaking an additional quart into the sump) there's less chance customers will get an oil-level warning."

Sound familiar?

Interestingly "Insiders at BMW in Germany say the oil consumption happens to customers who don't ever flog there powerful, turbocharged V8's hard enough to fully break them in." Tell it to the judge :=)

The article goes on to relate how, in the interest of fuel economy, the battery BMW choose is under-sized and under-charged so running the fans after shutdown (to cool the turbos) is killing batteries. The fix according to BMW is...install a new battery at every oil change (i.e. 10,000 miles)!

So, we are not alone. But lest GM think they're off the hook: "Rather than waiting for them to break, BMW NA is proactively replacing the parts with improved components through it's shrewdly named Customer Care Package or CCP. BMW says the CCP represents it's commitment to the long-term reliability of our most technologically advanced products."

My advice to GM: These days when even an econobox has a long list of features, there are evermore 'premium vehicles' to choose from. 'Premium service' would be a way to set Cadillac apart.
