Lots of incorrect information...  just think about how much this loud mouth makes on Youtube with clickbait headlines.

Comparing first to third generation sale figures is ignorant of the drastic change in price class.  What would be his explanation for the drop in Lexus GS sales (their CTS equivalent) and discontinuation over a similar time frame? 

Sorry, PCV design (flow volume) is not the *root cause* of excessive oil consumption experienced on some examples.  The engineers know what's required to control internal contamination, but it's difficult to account for supplier and owner variability.  Once the problem develops, it's possible that reducing flow volume may mitigate the loss, but there would be side effects depending on the driving and maintenance schedule.  Why doesn't he bring up the fact that *insufficient* PCV volume (poor design, lack of validation) was responsible for chronic sludge problems in the 1MZFE and other Toyota engines, which persisted for over well over a decade?  Why do so many 2ZRs (1.8 L) suddenly start emptying their crankcase beyond the 100,000 mile mark? 

Every manufacturer has common issues with each model, specific to certain model years.  There are many different 3.6s, and improvements have been made over the years to address weaknesses associated with different technologies.

Buick had a bullet proof 3.6L engine and the car wizard raved about it the full sized Buick , then they stopped building it.

I assume you're referring to the Buick 3800.  Even "bulletproof" 3800s have their pluses and minuses depending on the model year and Series.  The tooling to make that engine dated back to the '60s and it was literally wearing out and manufacturing ceased in 2008.  It seems there was a decision to phase out cam-in-block passenger car V6s, probably due to pressure from marketing.  For the few remaining years, the 60 degree 3900 carried the torch. 

It's a shame practically all manufacturers have adopted a "one size fits all" cost optimization plan.  North Americans now suffer with narrower vehicles that are capable of navigating some Old World cobblestone street that we'd never encounter here.  We are forced to accept small displacement engines (some with compensatory hardware for forced induction) even though no displacement taxes exist.  The best solution from a consumer standpoint (on this continent) is a simple design, which usually dictates cam-in-block and a larger displacement; less complexity and low stress translates to low maintenance/repair costs over the long haul.  Low load efficiency can be achieved via cylinder deactivation, which is generally more effective the larger the displacement.  With enough boost, there's no doubt a small displacement engine can keep up or even surpass (depending on the design objectives) a naturally aspirated equivalent in acceleration performance (over a finite period), but as with everything, there's a compromise.  Small turbos tend to do be more efficient at low outputs, but once into sustained boost, the required fuel enrichment to control piston temperature takes its toll on BSFC; this difference is particularly striking while towing.  Higher power density (specific output) is always associated with higher ownership costs.

I know Scotty Kilmer is a blowhard and he's pro Toyota all the way so some of us had a good laugh. The CTS V would be the hot Cadillac to own.So far GM got it right with the Corvette , Cadillac has dumped their budget into the SUV's , where the money is , they design and build cars for the China market. Cadillac will be their electric car brand soon anyway.
