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. Repair order 184931 documents the stalling complaint and reports of misfires on cylinders 2, 4 and 6. It records multiple test…

I noticed my driver head light starting to get condensation after doing further research i found itâs a common manufacturer defect especially for the g70s. I took a further look by removing my front bumper & noticed 3 cracks starting from each screw on the front of the headlight mounting. after doing more research i found out itâs a common manufacture problem with over torquing the screws & after inspection thatâs exactly why my headlight lense is cracking from bottom to top, as itâs too much force where the screws are & with hot & cold temperatures plastics & such move creating them to break. my safety is put at risk due to the corrosion building in the headlight causing my blinker…

While driving my Genesis G70 on the highway in rainy conditions, the vehicle repeatedly loses traction and hydroplanes at normal highway speeds. The car begins sliding across lanes with very little control. During a prior incident, driver-assist features (lane keeping assist) were active. Rain appeared to interfere with the sensors, and the system malfunctioned by steering incorrectly. The steering wheel became difficult to control, and the vehicle attempted to steer into another lane while traction was already compromised. The vehicle hydroplaned across multiple lanes of the expressway, creating a high risk of collision. The systemâs steering input did not match driver intent and made…

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.

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…
