What 2023 Genesis G70 owners say
Engine & cooling
The fuel delivery system, specifically the fuel pump and fuel rail pressure system, has malfunctioned and continues to trigger diagnostic trouble code P0191 (fuel rail pressure sensor range/performance), despite a prior recall-related software update performed by the dealer, and the vehicle and all affected components are available for inspection upon request. While driving on the highway, the vehicle suddenly began stalling, hesitating, and hard jerking before losing power and entering limp mode, limiting speed to under 50 mph and forcing me to immediately pull over, which created a serious safety risk to myself and other drivers due to the sudden inability to maintain highway speeds. …
While accelerating to highway speeds, the vehicle suddenly experienced a significant and continuous loss of power. Even with the accelerator fully pressed, the vehicle would not increase speed beyond roughly 50 mph. 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. Hazard lights had to be activated, and the vehicle remained in the slow lane for an extended period to avoid faster-moving traffic. The issue was consistent and repeatable throughout the drive. Multiple attempts to accelerate resulted in the same lack of response, and the loss of power persisted for the duration of the trip. …

Fuel & propulsion system
The car randomly goes into LIMP mode when driving in every condition going at any speed, the car has a significant loss of power and needs to be restarted to gain power back. I have almost crashed because of this problem numerous times. Genesis dealership refuses to fix anything because the car doesn't bring back any error codes. This has happened to new and older G70s, there has also been numerous LEMON LAW buy packs under this exact LIMP mode issue being way more prevalent. I have gotten the supposed "fuel pump" recall which is what is directly affecting this issue and the problem persists. Genesis is aware of the issue and extended the dual pump warranty extensively. My car is extremely unsafe at random intervals during my daily commute. This issue is extremely dangerous and could cause a horrific crash. …
