2025 Genesis GV70

This supplements my prior complaint, ODI #11751961, for the same vehicle. Following that complaint, an authorized dealer performed front camera and front radar ADAS calibration on 7/21/2026 and returned the vehicle as operating as designed; the manufacturer's representative confirmed in writing on 7/22/2026 that the camera had been within specification. On 7/23/2026, approximately 1:21–1:35 PM, driving in the left lane of a divided parkway with a concrete median barrier, with HDA2 and Lane Following Assist both active and indicating green, the steering wheel turned the vehicle toward the concrete barrier at least seven times, requiring manual correction each time. This occurred both with a lead vehicle approximately 4 seconds ahead and with no vehicle within more than 10 seconds ahead. Earlier the same day, driving the opposite direction with both systems active and green, the vehicle applied hard automatic braking twice with no vehicle within more than 10 seconds ahead (traffic present only in the adjacent lane); I had to manually accelerate because a following vehicle was close behind. My original complaint reported the automatic braking failing to activate; the system now also activates falsely. Additionally, the hands-on-wheel warning repeatedly illuminated while my hands were on the wheel, taking approximately 30 seconds to detect them. I have stopped driving the vehicle. The manufacturer was notified in writing the same day, and a second repair visit is being arranged. No crash or injury has occurred.

When Highway Driving Assist / Lane Following Assist is active — confirmed by illuminated green HDA and lane assist indicators — the vehicle applies uncommanded steering torque, to the left or to the right, strong enough to force the vehicle out of its lane. This occurred on every drive, daily, from delivery on 7/2/2026 (approximately 23,200 miles) until the vehicle was brought in for service on 7/13/2026. The behavior was identical regardless of lane markings (solid, dotted, or absent) and road geometry (straight or curved), at highway speed and on local roads at approximately 30 mph. On multiple occasions the vehicle was pushed toward highway barriers (concrete median and metal guardrail, on both left and right sides) and into the oncoming traffic lane; avoiding barrier contact or returning from the oncoming lane required forceful manual correction, during which the rear of the vehicle oscillated side to side before directional control was fully regained. This occurred regardless of speed. Separately, the forward collision-avoidance / automatic emergency braking system failed to activate on multiple occasions when approaching stopped or slowing traffic, requiring hard manual braking by the driver. No warning lights displayed. An authorized dealer inspected the vehicle 7/13–7/21/2026: scans found no stored diagnostic trouble codes, road tests did not reproduce the behavior, and the dealer performed front camera and front radar ADAS calibration on 7/21/2026. I am currently monitoring the vehicle to determine whether the calibration corrected the behavior. A comparable loaner vehicle of the same brand exhibited correct HDA/LFA operation, which is how I confirmed my vehicle's behavior is abnormal. No crash or injury has occurred.

Incident

Jul 9, 2026

On June 8, 2026, while driving home from work and actively entering the freeway, the vehicle experienced a sudden, severe, and catastrophic loss of propulsion. Despite pressing the accelerator, the vehicle completely refused to accelerate beyond 30 mph, forcing me to navigate active highway traffic at a dangerously low speed. This sudden failure to accelerate while merging onto a high-speed interstate created an immediate, life-threatening situation, leaving the vehicle highly vulnerable to a severe rear-end collision. The vehicle was towed to an authorized Genesis dealership on June 9, 2026. Genesis Motor America (GMA) corporate customer service was notified, and Case #42801757 was opened. On June 25, 2026, the dealership stated they performed code scans and test drives but could not replicate the intermittent symptom or find any stored fault codes, declaring the vehicle ready for pickup without identifying or correcting the root cause of this severe defect. When challenged on the phone regarding the severe safety risk of driving a vehicle that unpredictably loses highway propulsion, the service advisor dismissed the life-threatening concern as "hypothetical." On July 3, 2026, GMA Customer Service provided their assessment on Case #42801757, rigidly stating the vehicle is not eligible for Lemon Law relief and instructing me to follow the dealer's advice to pick up the un-repaired car. Genesis is actively using the threat of immediate loaner car charges to force an unsafe vehicle back onto public roads. I am uploading the full email correspondence as evidence that Genesis corporate is forcing a vehicle with an unaddressed, life-threatening propulsion failure back into service.

Auto Start Stop seemed to have malfunction and shut the car off completely. I had to restart the car in traffic to get going. This happened twice, once going to work and once on a weekend trip to New Jersey. The only thing that's preventing an accident is you have to stop for the auto start feature to even activate.

My 2025 Genesis GV70 stopped accelerating properly. There is a lag when you push on the accelerator pedal and it must be pushed about 75% before it begins to accelerate. When it does accelerate it has much less power than normal. This fault occurs constantly. The car can't accelerate normally at any time now. This is definitely a very serious safety hazard. This behavior has been reproduced by Genesis service personnel. There are no warning lights associated with the problem and no diagnostic codes are signaled. After 24 days the Genesis service personnel have no idea what is wrong.

The contact owned a 2025 Genesis GV70. The contact's spouse stated that while attempting to make a turn, the brake pedal was depressed and the accelerator pedal was inadvertently applied. The contact's spouse was unaware whether any warning lights were illuminated due to the failure. The contact stated that the vehicle unexpectedly accelerated, causing the vehicle to crash into a sidewalk and then into a ditch. No injuries were sustained at the time of the crash, and no medical attention was sought immediately following the incident. However, the contact later suffered neck and knee injuries. The contact's spouse stated that none of the air bags deployed during the crash. A police report was filed. The vehicle was towed and was later deemed a total loss by an independent mechanic. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 1,100. The VIN was unavailable.

The National Highway Traffic Safety Administration (NHTSA) has identified the presence of substandard and dangerous driver’s-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self-inspection by vehicle owners and recommends inspection by trained technicians.

The National Highway Traffic Safety Administration (NHTSA) has issued an urgent safety advisory regarding dangerous, counterfeit driver‑side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd.
