2.5T Advanced, 2021, with 8k miles. Third time the CEL has come on, always the same code (P030400) showing cylinder 4 misfire. The dealer did nothing last time as the light went out on its own. This time, they swapped the 1 and 4 cylinder ignition coils and reset the light, waiting to see if the code re-appears, and if so if it localizes to cylinder 1 (coil issue) or 4 (engine issue). They could have easily done that last time as well but didn't. Thankfully, the dealer provided concierge pickup/loaner. Anyone else with similar issue or advice? Thank you

I have the same vehicle as you and the same problem! Had my vehicle in on Monday and they said there was a bad connection that was causing the misfire. Supposedly fixed the connection and all was good. Saturday morning, the check engine light comes on and my app reported the exact same code. Unfortunately, I live 1.5 hours from the dealership and have to dedicate a full day to go there and have service work done. In addition, I have already had to have my horn replaced and now have to have my headlight replaced due to a leaky seal and moisture in the headlight. I have only owned the vehicle a year and have been in the service center more than I ever was with any other past vehicle!
Ugh, sorry to hear about your issues. It might make sense to ask the service department to "swap" cylinder wires 1 and 4 as I mentioned in my post, as that can help determine the root cause and potentially lead towards resolution of this annoying problem. I guess the "good" news is that this code (and underlying issue) is not serious and it is safe to drive with the CEL on in this setting. I drive very little, and my CEL has not come back on since my last service in February 2022....but every time I start her up, I look for it! I will post again if it happens and particularly if the underlying issue is determined.

I've also had this same problem with my 2022 GV80 2.5T Advanced after 8500 miles, the first time I took it to the service department they said that they were able to reset the code and because the CEL went away they could find an issue. Two days later the problem came back, and they cleared it at the service department again but this time they ordered a part that's on backorder till thanksgiving, and a few days later the CEL came back for a third time. The service Rep told me the same thing (it's not a serious issue and it's safe to drive the vehicle with this CEL fault condition) but I don't trust them and also, I'm not real confident in there fix solution
I have a 2022 GV80 3.5T Advanced and the Check Engine Light goes on and off when I travel from Texas to higher altitudes. Told it is an 02 sensor issue and car is safe to drive. No one knows what is happening. Has been ongoing since I purchased the car. Since it goes off, and since they can reset the codes, the service advisors in Texas, Colorado, and California treat it as if it is a minor inconvenience and tell me not to worry. Not at all impressed.

I purchased my 2021 GV80 on January 15, 2023 from Palm Chevrolet of Ocala. The mileage when sold was 23,110. On the 17th of January, the engine light came on;I returned home and immediately called your dealership, Hyundai of Ocala; I was told to bring the car in that afternoon for a diagnosis. Service proceeded to order the necessary parts which included an Injector, seals, and high pressure fuel pipe, an appointment was scheduled for February 8. On February 8, I waited 5 hours for work to be completed. On February 11, I was excited to take a short trip to Bradenton, Florida in my new car. About an hour into the drive the engine started misfiring and bucking frantically, then after 5 minutes the engine light came on and stayed on. The car also has some kind of stuttering problem in the drivetrain, rear end, or transmission.
I’ve been a Genesis/Hyundai customer since 2006. Love the quality, so I thought. I am very disappointed in the drivetrain with this beautiful vehicle. I’ve had so much confidence in the Genesis brand, now I’m not so sure. Only saving grace is I have the balance of a five-year 60,000 mile warranty. My hope is that my GV80 is not being serviced every time I drive the vehicle. I have seen a lot of complaints about the engine lights on 2021 models since I’ve started my research on the internet. My hope is the car will be fixed and I’m done with these issues.
Update- after 8 or more trips to the dealer and innumerable conversations with national Genesis customer service, I raised the issue of "lemon law" and was offered two choices: cash settlement (keep the vehicle for lease duration with a small cash refund) or repurchase. Because I had leased the GV80 with a single payment 36 month lease, they offered me a significant portion of my original one-payment lease if I chose the repurchase...which I did. The process was relatively smooth but by no means "concierge level" service...inconvenient and callous, I would say...but it is done, and I have moved on to another brand, probably for good.
