2019 Genesis G70: engine stalls while driving

Filed Sep 10, 2026 · Fuel system · 35,000 miles · MD

The contact owns a 2019 Genesis G70. The contact stated that the vehicle was experiencing starting issues. Additionally, while driving 15-20 MPH and coming to a stop, the vehicle stalled and lost motive power. The vehicle was turned off and restarted and was able to drive to the intended destination. The contact stated that the failure recurred and progressively worsened. While researching the failure online, the contact discovered that the failure was a common issue. The vehicle was initially taken to the dealer, where an unknown software update was performed, and the check engine warning light illuminated during the failure. The vehicle was taken back to the dealer, where it was diagnosed and determined that the fuel pump had failed and needed to be replaced; however, it was determined that the failure was not covered under warranty because a specific DTC indicating that the fuel mixture was too rich was not retrieved. The manufacturer, Genesis, was notified of the failure by phone, filed a case, and scheduled a service appointment with a dealer for the contact. The failure mileage was approximately 35,000.

I own a 2019 Genesis G70 3.3T Twin-Turbo V6, VIN [XXX], with approximately 122,000 miles. Twice within approximately two weeks, the vehicle has suddenly and unexpectedly experienced a near-total loss of propulsion while being driven. Without warning, the engine begins shaking and sputtering severely, the Check Engine Light illuminates, and the vehicle provides almost no usable acceleration. The engine does not completely stall but operates barely above a stalled condition. After safely stopping, turning the vehicle off, and restarting it, normal engine operation and full power immediately return and the Check Engine Light extinguishes. The vehicle may then operate normally for days before the condition occurs again without warning. This creates a serious safety hazard because the failure could occur while traveling at highway speeds, merging, changing lanes, or crossing traffic. A sudden near-total loss of propulsion under those circumstances could result in a serious or fatal collision. I have found reports from other Genesis G70 owners describing substantially similar intermittent loss-of-power conditions that temporarily resolve after an ignition restart. Genesis has also issued safety recalls involving G70 powertrain-related conditions, including the federal safety agency Campaigns 24V‑528 and 24V‑191. I have formally notified Genesis Motor America in writing and requested immediate investigation and repair. I am submitting this complaint so the federal safety agency has an independent record of this recurring and potentially dangerous loss-of-propulsion condition and can determine whether it represents a broader safety defect affecting Genesis G70 vehicles.

5 times in the last 3 months the vehicle stalled while coming to a stop to put in park once, and 4 other times when the vehicle was off and parked, then started. The vehicle immediately began to stall out sounding as if it wasn't getting enough fuel. The last 2 times it stalled when being started, the vehicle remained on once I gave it a little gas by pressing the gas pedal when the stall started. The dealership is aware and performed a software update stating no components needed replaced and to keep an eye on it and a record of when it happens. Although it's believed to be an issue with the fuel pump, this specific one is not listed under the fuel pump recall.

When driving the vehicle it feels as though as it stalls due to choking all or some of the fuel getting to the engine. This is most prone when accelerating fast. It feels as though the fuel is shut off or severely diminished as the vehicle will accelerate, but at a fraction (crawl) of the normal output available and accomplished in the past.

Engine stalled when stopped at a traffic light. There was heavy traffic in front and to the rear of my vehicle. I was in the far right lane. It was 102 degrees outside. I was able to restart the vehicle about two minutes after the initial stall. I was then able to drive the vehicle to my home where it was then towed to the nearest Genesis dealer. No warning lights. Dealer stated no error codes were found and they could not duplicate the problem. After pushing for a solution they stated they will replace the fuel pump. Seems to be an ongoing, extremely dangerous problem with Genesis owners vehicles.
