the problem is getting long in the tooth now. If there ever was a CALS, I don't remember it.
I bet you can pick almost any car maker though, and search google with its name plus the phrase 'class action law suit' and find several. My Brother-in-law's Hybrid Camry suffered a seized engine DURING an excess oil use test! Personally, I think it's sad that there are basic issues like head gaskets, wheel bearings, piston ring lands and other areas that should have decades of good engineering experience behind them - that still suffer early failures. Other makes have stuff like this come-up too. Yes, the 2016 CAFE standards are very tough, but some of these issues aren't related to that.
