The V6's fifteen-year engine coverage — the most valuable fact on this pagemajor
- 3.3L GDI Lambda II V6
If the car has the 3.3-litre V6, Kia's own bulletin gives you a free engine under specific conditions. Warranty Extension Program WTY035 covers 2016 and 2017 Sorentos with the 3.3-litre GDI Lambda II engine, built between October 2014 and April 2017. Kia's words: dealers are to "diagnose a coolant leak from the cylinder head gasket area and, if necessary, replace the engine sub-assembly", and "the warranty coverage for related repairs will be extended from 5 years / 60,000 miles to 15 years / 180,000 miles, whichever comes first, starting from the date the vehicle was first put into service." The symptoms Kia lists are a coolant leak, a coolant smell, or the temperature gauge sitting near the H mark. If a 2016 V6 Sorento smells sweet after a drive, that is not a reason to walk — it is a reason to book a Kia dealer appointment before you negotiate. The V6 is not trouble-free otherwise: owners also report seizures, including "my 3.3 V6 engine on my 2016 Kia Sorento seized up with no warning. There is no visible oil on the dip stick."
