2026 Genesis GV70

Day after purchasing gv70, upon starting vehicle, the brake pedal went all the way down to the floor. After taking foot off brake and reapplying foot pressure, the pedal responded accurately and I started the car. This occurred a second time and upon the 3rd time, I contacted the dealership. The third incident occurred with 4300 miles on it. First incident under 500 and second under 750

Incident

Sep 24, 2026

The contact owns a 2026 Genesis GV70. The contact stated that while driving approximately 14 MPH, the automated brakes independently and violently engaged. The sudden braking caused the contact’s head to strike the driver’s side door frame, resulting in a head injury and a brief loss of consciousness. There were no warning lights illuminated prior to the failure, but the vehicle entered "Emergency Mode" during the failure. Medical attention was required, resulting in an emergency room visit. The contact stated that after the failure, the power seats became inoperable and batteries were draining abnormally. The battery failure locked the doors, and the vehicle was taken to the dealer to unlock the doors due to the failure. The vehicle was taken to an authorized dealer, and the vehicle was diagnosed with misaligned and low-facing radar sensors that were tracking the ground. The manufacturer was notified of the failure but could not assist because there were no fault codes retrieved. The failure mileage was 100.

On August 1, 2026, the right rear passenger door of our Genesis GV70 opened while we were traveling approximately 75 mph, approximately 25 minutes into our drive. We purchased the vehicle new on March 20, 2026. During the approximately 25 minutes of driving before the incident, we received no door-open or door-ajar warning. The warning first occurred when the door physically opened, providing no advance indication that the door might not be secure and no opportunity to stop before it opened. My daughter was seated beside the right rear door and was leaning against it when it opened. She had to grab the door and physically hold it shut. This created an immediate risk of serious injury to an occupant at highway speed. My safety complaint concerns both the door opening while the vehicle was moving and the timing of the door-warning system’s activation. I cannot determine whether the door was improperly latched before the incident, whether the latch failed during the drive, or whether a sensor or other component malfunctioned. What we observed is that no warning was provided during the preceding drive; the warning activated only when the door opened. We delivered the vehicle to the dealership on August 4, 2026. The dealership has retained it for investigation but has stated that it cannot duplicate the door incident. We have not been provided with an identified cause or a confirmed repair addressing the door opening and warning behavior. We have also reported recurring electronic problems and supplied the dealership with videos documenting those issues. I request that NHTSA investigate the door-latching mechanism and associated door-warning system, including whether an unsafe door condition can remain undetected or unreported until the door opens while driving.

The vehicle intermittently and unexpectedly shifts itself from Drive (D) into Park (P) while completely stopped in active traffic. When traffic moves and the accelerator is pressed, the engine revs safely in place, but the vehicle does not move because it has uncommandedly entered Park. The driver must quickly apply the brake and manually shift back into Drive to avoid being rear-ended. This has occurred on 6 separate occasions within the first two months of ownership, creating an immediate, severe collision hazard at active intersections. Dealer/Manufacturer Actions: The vehicle is currently on its 3rd service visit at Genesis of Lindon for this exact issue and has been out of service since August 10, 2026 (accounting for 11 business days on this visit alone, and over 20 calendar days total across all visits). The dealership has been unable to replicate the intermittent electronic/software fault during limited 15-mile test drives. No error codes are stored, and no dashboard warning chimes or lights appear when the uncommanded shift occurs. A corporate case has been opened with Genesis Motor America, and a formal written notice under the Utah New Motor Vehicles Warranties Act has been submitted. The vehicle is currently deemed unsafe to drive by the owner and remains at the dealership.

Component Focus: ENGINE AND ENGINE COOLING / VISIBILITY/WIPER/DEFROSTER (HVAC) Description of Safety Defect: My brand-new 2026 Genesis GV70 Turbo (under 5,000 miles) suffered a sudden, catastrophic cooling system and heater core failure while in operation. The vehicle has a severe design defect: it completely lacks a low-coolant fluid level sensor in the expansion reservoir. Because of this engineering omission, the vehicle dropped its coolant level completely below the minimum safety line and filled the enclosed passenger cabin with highly toxic, atomized ethylene glycol (antifreeze) chemical vapors through the HVAC vents without triggering a single dashboard warning light, chime, or error code. The climate control system simultaneously malfunctioned, dropping fan speeds when stopped and forcing occupants to breathe in the concentrated toxic fumes. This is a severe health and safety hazard. A driver could easily be overcome by hazardous chemical vapors or experience sudden engine failure at highway speeds because the vehicle provides zero electronic warning of a critical coolant loss. Local authorized dealerships refused to accommodate the vehicle or provide a safe loaner vehicle despite the car being completely undriveable and chemically hazardous to sit inside. The vehicle is currently disabled at a dealership

While driving at 35mph on a straight section of road the warning sounded, the display said "steering wheel locked" and I could not turn the steering wheel for about 5 seconds, then it returned to normal operation. We bought the car new in July 2025. I found numerous posts on line describing similar or worse experiences. The dealership performed tests and could not determine a cause.

On XXX while driving at approximately 5mph in a parking lot my Genesis GV70 shifted from Drive to Park by itself causing the car and my wife and I to lurch forward and come to a stop! The car would not come out of Park and a warning came up after the fact saying to contact immediate service. My wife and I were in the car and there were no injuries. If this occurred at a higher rate of speed on a busy highway I cannot imagine what would have happened. I immediately called Genesis Road Assistance for a tow. The car was towed by flat bed to the dealer in [XXX], where I purchased the car, approximately 10 miles away where it sits today waiting for service. My wife and I are afraid to drive this car ever again as it is brand new with only 250 miles on the odometer. *No warnings of any kind prior to the incident.
