Genesis needs to improve quality control and service.
I spent a month to research. I watched and read all reviews of GV80 on Youtube and any websites. All praised GV80 as a new hidden gem except two reviews with "harsh ride". Since GV80 has a beautiful design with all cutting edge features, and long warranty, I did couple of short drive tests and bit the bullet (Note: 3 Genesis dealers gave me cars with an almost empty tank to test drive). I bought a GV80 advanced+ and immediately regretted after the first trip . Oh man, the suspension is too firm which it indents all road defects on my seat. There is no way to adjust the suspension even if I change the drive modes. The firm suspension causes vibration and rumble noise above 60mph. Worsely, my brand new GV80 got few problems right out of the dealer's door. It vibrated around 75mph with whooping noise. It is like something out of balance (tires, driveshaft, differential...). Also, the wipers were squeaky. They even knocked under heavy rain. When I tried to book an appointment for the problems online, the next available slot is 28 days from now. I had to drive back to the dealer to escalate the complaint. The service manager did a test-drive, acknowledged the vibration and the noise but it took another 10 days to rebalance the tires. All problems or services have to wait days/weeks to serve.
In my opinion, think carefully if you are from a luxury car like Lexus, Mercedes, BMW... Genesis provides more luxury features, longer warranty with lower cost. But these are QUANTITY. The QUALITY is far lower than other luxury brands.
