Genesis GV70 Electrical problems by year

barely accelerate after first starting it. After driving a mile, I pulled over and restarted the car. This was the only time I saw the "a" warning light go to "yellow". 4) after driving a while, the infotainment system went black and the radio volume increased to max. I could not turn the volume down even with the manual controls. After 10 minutes the screen came back but I still didn't have control of the volume. I pulled over and restarted the car and it fixed the problem. Today, [redacted], I went to the dealer (Genesis of [[redacted]]) and told them all of the above and how scared I was with the acceleration. They set up an appointment for two weeks from now and said it was safe to drive. I do not feel safe driving the car. It is a 2025 Genesis GV70 and under warranty.

would not allow me to change the gear. I turned the engine off and restarted the vehicle, but I was still unable to shift the vehicle into Drive. I attempted this three times. On the third attempt, the vehicle finally allowed me to shift into Drive, but the check engine light remained illuminated. I subsequently took the vehicle to the dealership for inspection. The dealership stated that they updated the vehicle's software and reset the error codes. I am reporting this incident because the vehicle unexpectedly began jerking in heavy traffic, displayed multiple warning/error messages, and temporarily prevented me from changing the transmission gear. The inability to shift the vehicle normally and the sudden jerking created a potentially dangerous situation while driving on the expressway.

additional times this may have occurred unobserved. Dealer states it was unable to duplicate this condition during a test drive. During this same visit, the right front CV axle was found to be leaking grease and had lost lubricant, and required full replacement. Both front horns were also found inoperable/defective due to internal short and were replaced. Neither of these conditions had been previously reported as faulty prior to this visit. Separately, this vehicle has experienced a steering column defect. At approximately 9,000 miles, a steering wheel squeak was reported and a dust cover was replaced. During that same earlier visit, an intermittent loss of acceleration was also reported; the dealer was unable to duplicate this concern and documented the vehicle as "operating as designed." Weeks after that visit, a knocking noise developed in the steering column. At approximately 10,000 miles, a technician found a structural through-bolt in the steering column not torqued to manufacturer specification and corrected it. Dealer advised in writing that this defect was likely present at the time of manufacture. The vehicle has been taken to an authorized dealer on multiple occasions for these concerns. The owner has repeatedly requested, in writing, a detailed explanation of what was diagnosed, what was repaired, and the underlying cause of the movement, the axle failure, and the horn failure, and has not received a substantive written response as of this filing

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.

until late September". Clearly, no one at Genesis at the dealer level or corporate cares enough to help me solve this problem so I am forced to find an independent mechanic who can work on my vehicle and rent my own car until it's repaired. This is completely unacceptable especially for a luxury vehicle. First, not being notified of a problem Genesis has known about for a long time so i could repair it before it's become a calamity (where i am now). Second, no one cares enough to help me solve their defective parts problem! I expect Genesis to pay for both the repairs and my rental plus any additional out of pocket expenses.

MATERIAL: Before this crash the vehicle STARTED ITSELF TWICE WITH NO HUMAN COMMAND - no key press, no remote start, nobody in it. Separately the entire system went completely black, causing TOTAL ECU AND ECM FAILURE. The vehicle lost electrical integrity. WHY THAT MATTERS: Genesis Service Campaign 914G is "ECM Update - P030X Misfire"; its remedy is "Update the ECM (Engine Control Module) software." It covers 2022-2023MY GV70 (JK1) built 3/29/2021-3/4/2025, VIN starting KMU. My VIN is [[redacted]], a 2023 GV70. Owner notice was due September 2025. The campaign was still open and unremedied when the car crashed 12/3/2025. THE EVENT: Exiting a highway at low speed with no impact, collision or obstacle of any kind, the airbags deployed spontaneously. The deployment caused loss of control and a three-vehicle collision. The deployment caused the crash. No warning lamp or symptom preceded it. FAULT HISTORY: B139500 cross coupling (SRS firing-loop interconnection fault), B1650 (airbag control unit fault history), and multiple LOW VOLTAGE codes. An electrical system that starts an engine uncommanded and blacks out an ECU can fire a restraint with no crash. EDR: The report states the EDR is part of the Air Bag Control Unit and that if ACU power is lost during an event, all or part of the data may not be recorded. Manufacturer closed its claim with no repair or explanation. Vehicle and ACU remain available; no dealer diagnostic was done on the ACU.

The vehicle was reported to the manufacturer, which opened a claim and later closed it without repair or explanation; a second manufacturer case review is open. I have demanded preservation of all vehicle data, including event data recorder and telematics records, and independent inspection was arranged. The vehicle and the airbag control unit remain available for inspection on request. The problem has not been reproduced by a dealer, and to my knowledge no dealer diagnostic has been performed on the airbag control module.

(module was replaced), and a persistent rear hatch malfunction that has never been resolved. The most serious concern is that the vehicle has, on multiple occasions, unexpectedly shut down while being driven, including instrument cluster and infotainment screens going dark, occurring when the automatic engine stop/start feature engages at intersections. The vehicle has restarted on its own after acceleration in some instances. Power steering assist has also been affected during at least one of these events. Most recently, the vehicle failed to start at all on one occasion, requiring roadside assistance to jump the battery; the dealer diagnosed unstable battery voltage but did not identify a root cause connecting this event to the prior shutdown incidents. This creates a significant safety risk due to potential loss of vehicle control or loss of power while operating in traffic. The problem has been reproduced and confirmed by the dealer on multiple occasions (door module and wiring harness failures were diagnosed and repaired), though the shutdown-while-driving events specifically have not been duplicated by the dealer despite multi-day testing. The vehicle has been inspected exclusively by the authorized dealer; it has not been inspected by police or independent parties. Warning symptoms (flickering door lights, dead door controls) preceded the shutdown/stall issue by roughly a year before the stalling symptom began.

monitor. The replacement failed in the exact same way, proving the issue is not hardware-related. When the driver-side display goes black, I lose critical driving information, creating a clear safety concern. They refuse to update software.
