Does the 2018 Genesis G80 have engine or transmission problems?
Not as a pattern, going by owner complaints. 18 of 84 relevant complaints filed with NHTSA about the 2018 Genesis G80 concern the engine, transmission or fuel system (21%). For comparison, the 2017 scores 34% and the 2019 scores 22%. This describes the model year, not any one car: a well-maintained or already-repaired example can be fine, and a clean model year can still have a bad car in it.
Manufacturers fix things mid-generation. A bad year next to a clean one is common; the fix usually arrived in between.
