So I don't own one but I know someone who does (2012 Santa Fe 2.2crdi) and we discuss the vehicle fairly regularly. The vehicle isn't serviced as regularly as it should and it currently has above 180000kms on the clock.
The engine has decent power for its displacement, with no visible intercooler.
It requires a new harmonic balancer (crank pulley) every 100000kms or roughly when the drive belt has to be changed. It currently has what sounds like a loud chain rattle on engine startup which developed over time. The transmission feels like it's slipping if the fluid is left in there too long, and it needs to be changed even though the manual says "lifetime" fluid (Their version of the word lifetime is usually just the warranty period). The brake lines from the master cylinder have some short rubber connections which are prone to failure. The fuel filter is in a tough spot to access/work on. At least one speed sensor will fail before 100000km s. Our diesel fuel doesn't meet the requirements as stated in the manual so expect to be putting some form of cetane booster, more frequent oil changes and more soot
The longevity/reliability really depends on how the vehicle is serviced...in this vehicle's case even more so.
