<raises hand> After a '13 Sorento that ran flawlessly, and a '17 Sorento that ran flawlessly, and a '19 Sorento that runs flawlessly, all with the 3.3L V6...I heartily recommend Sorentos.
When people base their car buying decisions on the loudest voices on an internet forum, they're doing no better than just throwing a dart to see where it lands. "Oh gawd, Sorentos suck! But now I see this one post on a RAV4 blowing up...Toyotas suck! Oh, wait, here's one post about an Outback that fell apart...Subarus suck!"
As a counterpoint, you shouldn't ignore the complaints since the frequency and popularity also is a factor. If you take 2016 CR-V's, RAV4's and Sorento's data on CarComplaints, you'll find the 2016 RAV4 having few overall complaints despite selling 352,154 units in 2016, the CR-V at 357,335 and the Sorento trailing with 114,733 sold. (of course, it may not be 1-to-1 since it's likely calendar and not model year)
The CR-V technically has more engine category complaints than the Sorento, but they are primarily labeled "Vibration At Idle". Potentially annoying but not a major problem.
(I'll be a little unfair to the CR-V and include the 2017MY too, high complaint counts for oil dilution - a big concern for 1.5T models and can cause issues but one can still change oil more frequently and is a longer-term concern compared to both 2.4 and 2.0T Theta II engines with their knack for knocking - or seizing unexpectedly.)
The Sorento has a similar amount of engine category complaints, except instead of just vibration, it's "Engine Failure".
If we pop on over to RAV4world or CRVOwnersClub (or others like ClubFrontier, Piloteers, etc.) you'll of course find problems, but you won't find the "it's my turn for engine failure guys!" attitude we have here and I say that's a reflection of the rightfully earned bad rap of HyunKia engineering.
I got curious a while back and went looking to see what the cost/procedure to fix the AWD clutch in something like a Crosstrek, Highlander (gas models), etc. and they just don't seem to have that same level of failure that we've seen here. (could it be programming, engineering, etc?)
