2023 Genesis G70 Engine Problems

“Dealer did not complete recall while in service Nov 15 2024, service order shows parts are on back order. After 2 months I reached out to Corp who reached out to dealer. Both copr and the dealer ended up calling back just yesterday, however the message from copr stated the part is ordered it's way but the message from the dealer stated software upgrade needs to be done first before ordering parts. But why software upgrade was never done 2 months ago while performing service? I can smell excess gasoline 5 mins after remote started and my thermometer temp spikes significantly upon start. …”

“I have had my car for almost 6 months and in that time frame twice my car while driving on the highway my car went into limp mode and was not responding. I was unable to accelerate. It was almost like I wasn’t able to control my car. All lights on the dash came on. I recieved DTC error code p061b00. My car so far has 7000 miles on it and I leased it in November 2023. After shutting the car off for a while the car would go back to normal with just the check engine light and and shortly after the check engine light would go away too. I don’t feel comfortable driving my vehicle at this point. …”

Based on the behavior and previous service history, the issue appears to be related to the engine, fuel delivery system, or overall powertrain. The incident created a serious safety concern for both the occupants and surrounding traffic. The vehicle could not properly accelerate, merge, or respond to normal highway conditions. …”

“My 2023 Genesis G70 has recurrent, intermittent engine power loss and stalling while driving, including on highways. The check engine light comes on intermittently and the engine can run roughly. After a stall, restarting can restore operation, but the issue recurs. Unexpected power loss in highway traffic puts occupants and other road users at risk. The exact failed component is UNKNOWN. The vehicle had repeated prior visits to Genesis of Auburn without resolving the concern. Southtowne Hyundai and Genesis of Newnan held it from August 19 to September 4, 2026. …”
