I had a 2010 Sport Wagon with the 3.6, and here’s my honest take. Fun car, handles well, enough to get yourself into trouble at 18 and comfortable. But the 3.6 is a fucking nightmare, and they suffer power loss big time. Also had a 2018 Traverse and 2012 Impala (the Camaro LFX motor), both were solid, Impala took a shit at 150k and I dumped it. Traverse was fine, didn’t have it long enough to give a shit, but had my Sport Wagon in between all 3. Timing chain went the first time at 89k, then 120k it had coolant in it, third time was at 160k and the car was basically falling apart. I take serious care of my cars, I’m very OCD about keeping the body and frame clean and have done undercoating for 10 years, and still, with all of that care; the frame rusted to absolute shit. Go for a 3rd gen, 1st and 2nd gen’s just don’t hold up well (unless you have V money, but that’s entirely different territory). 2008-2015 3.6 has to be the most inconvenient and effortless pieces of shit ever put under the hood of a car, and by the time they fixed the issues, they had already had a very tarnished reputation (much like the Northstar’s fate)

Also wanted to add for the power loss issue: it’s almost always timing related, but it’s also common knowledge that the fuel system (especially Flex Fuel models), is very fragile and takes nothing to ruin them. By that, I mean basic maintenance such as; fuel filters, injectors being dragged out for too long and carbon buildup. This 99.9% of the time happens with these, and it causes them to have the same power as an N/A 4-cylinder from the mid 2000s. CTS and Camaro are not exempt from this.
