My tracking number assigned by NHTSA for this issue is XXX. I am adding additional pdf.s to this original safety On page 4 of 8, the attachment MIP from Genesis on HHI does not provide a reason for this concern: High Pressure Fuel Pump With Seal Cam Lobe Bucket HPFP Bolts Fuel Rail Pipe Intake Manifold Gasket Throttle Body Gasket Item Description: Speak with your service advisor for more information on this recommended service. Reason: Left blank Service Advisors' texts attached: 1, 2, and 3 from [XXX] of Genesis/[XXX] of HHI: The dealership’s verbal assessment was that the fuel pump area bolts sheared off due to "outside work" or "over-tightening, I asked for photos to provide visual, metallurgical proof of tool marks or cross-threading to back up that claim, and [XXX] verbally stated they had submitted those to Genesis. I never received the photos. The last attachment (Diagnostic Check). **RESPONSE to dealerships' speculation: ** Under Federal Recall 033G (NHTSA Campaign 26V229000), which directly involves the failure of fuel system retention fasteners, the Insufficient torque on the stabilizer bolts is prone to a bolt backing out even a fraction of an inch; the fuel assembly begins to vibrate violently against it. This creates immense lateral (sideways) fatigue stress on the bolt threads. Eventually, under that continuous vibration and stress, the metal fatigues and shears (snaps) completely off.

FUEL/PROPULSION SYSTEM

Subject: Vehicle Safety Incident Report – Fuel Pump Disconnection and Oil Leak To: National Highway Traffic Safety Administration Date: July 27, 2026 I am submitting this report to detail a recent vehicle malfunction that posed significant risks to my safety and that of others on the road. While driving to work, I experienced a situation where my vehicle was unable to shift gears properly or accelerate as expected. This loss of acceleration and responsiveness created substantial control problems, making it difficult to maneuver safely in traffic. Notably, no dashboard warning lights were illuminated at the time, which gave me the false impression that the vehicle was operating correctly. Initially, I perceived a dragging sensation in the car, which I believed was manageable. However, the situation quickly escalated when I observed smoke coming from the vehicle. The presence of smoke not only impaired my visibility but also posed a serious risk of fire or engine failure. The danger was heightened as I attempted to drive uphill; the car struggled even more, increasing the potential for an accident or collision due to impaired maneuverability. Following this incident, I had my vehicle towed to an auto repair shop for a diagnostic check. The diagnostic report revealed that the fuel pump was not attached to anything and that oil was leaking into the pan. These findings confirm that the issues were real and not just perceived. The disconnected fuel pump and oil leak represent systemic failures, which could have had catastrophic consequences if not addressed promptly. In conclusion, this experience highlighted grave risks to both personal and public safety. I urge vehicle manufacturers and regulatory bodies to prioritize detecting and preventing such malfunctions.

2026 Genesis GV70 Ashburn, VA

FUEL/PROPULSION SYSTEM

I leased a 2026 Electric GV70 from Genesis in June 2025. In January of 2026, when driving the car I got a warning sign to stop the vehicle and check the battery supply. At that point, the car went into sever power reduction and would only go 20 MPH or so. After 20-30 minutes, the car completely shut down and became inoperable. Luckily, I was near home and was able to get my car home. I had to have the vehicle towed on wheels as it was completely frozen to the dealership. They diagnosed it as a failure of the Integrated Charging Control Unit (ICCU). They replaced the ICCU but identified other issues that to this day are unresolved and my car is still in the shop. These cars were subject to a recall for ICCU failure but only to model year 2025. These ICCUs are continuing to fail on the 2026 models, and at an alarming rate. The head of service at the dealership told me they were dealing with "hundreds" of ICCU failures on Hyundai/Genesis vehicles. If I had been on a highway traveling at higher speeds and the car suddenly lost almost all power and would only drive for another few miles before completely shutting down, it would have created a dangerous situation. These cars need to be recalled - again. Hyundai/Genesis clearly dont know how to make electric cars/battery packs that work and should be held accountable. I believe they are downplaying this situation due to the prior recalls/class action lawsuits and dont want to experience further reputational damage.

2026 Genesis GV70 West Bloomfield, MI

FUEL/PROPULSION SYSTEM

Without any warning, on March 15, 2026, I turned out of a parking lot onto a major road and I noticed it wouldn't accelerate above 20 mph, so I pulled off the road. I tried again and my vehicle still failed to accelerate. And on my third attempt, my vehicle decelerated and was about to completely stall. I managed to turn into a parking lot and avoid getting rear ended. However, this could have been a fatal event. While I was trying to accelerate, the vehicle was quiet as if the car wasn't even running. After shutting the engine off for awhile, I was able to drive the vehicle with caution. I reached out to two Genesis service departments regarding my vehicle failing to accelerate while driving and neither had heard any previous complaints, and the earliest appointment would be mid April. There was no sense of urgency, as I'm left to hesitantly drive my vehicle at the risk of it happening again and getting rear ended. And when my vehicle does go in for service, I'm weary whether the problem will be resolved properly since the service department is unaware of the issue. In addition, I have had this vehicle for only 4 months and 1 month into it, I already took it to service because of fuel odor that had not gone away since the day 1. But the service department didn't find anything wrong with the vehicle, so nothing was done to it. I also swung by another Genesis service department, in case they happened to be familiar with the cause of the odor. My vehicle still has the fuel odor and now I'm wondering if that is related to my vehicle not accelerating. I am seeking your assistance to ensure that the problems with my vehicle are confidently resolved. And I wouldn't want this to happen to anyone else. I am thankful, I was driving and not my teen.

2022 Genesis GV70 Fort Mill, SC

FUEL/PROPULSION SYSTEM

The high-pressure fuel pump failed, resulting in insufficient fuel delivery to the engine. This caused a significant loss of engine output, with the vehicle unable to accelerate beyond approximately 35 mph or stalling around 60 mph and exhibiting very slow acceleration. The lack of adequate power created unsafe driving conditions. I was nearly rear-ended while making a right turn and again while attempting to merge onto the interstate, as the vehicle could not accelerate as expected. There were no warning lights or prior indications of a problem on the dashboard. The issue first occurred on 2/21/2026, and I immediately stopped driving the vehicle. The vehicle has since been inspected by the Charlotte Genesis dealership, which diagnosed a high-pressure fuel pump failure.

2025 Genesis GV70 Atlanta, GA

FUEL/PROPULSION SYSTEM

My vehicle failed while in motion. I lost power to the vehicle and power steering. Just before the car failed, I heard a pop and a warning light came on that said "Check Electric Vehicle System". The car's ICCU failed and caused failures of the battery and 12v battery. My safety and everyone on the road around me's safety was put at risk when I lost the ability to accelerate or use power steering. The car was towed to a dealer and the dealer confirmed the issue. The ICCU failure and failure of the vehicle while in motion is directly related to a previous safety recall (025G) for which repair work was done on my vehicle. The recall repair was ineffective as the very issue it was intended to resolve still happened to me in a 1 year old car with only 8,000 miles.

FUEL/PROPULSION SYSTEM

National Highway Traffic Safety Administration Office of Defects Investigation 1200 New Jersey Avenue SE Washington, DC 20590 Subject: Safety Defect Complaint – Integrated Charging Control Unit (ICCU) Failure Vehicle: 2026 Genesis GV70 Electrified (EV) VIN: [XXX] To Whom It May Concern, I am submitting this complaint to report a safety-related failure involving my 2026 Genesis Electrified GV70, which experienced a sudden “Check Electric Vehicle System” warning consistent with a failure of the Integrated Charging Control Unit (ICCU). Incident Summary On February 5, 2026, at approximately 4,480 miles, the vehicle displayed a “Check Electric Vehicle System” alert and was no longer safe to operate. Due to the risk of propulsion loss and electrical system malfunction, the vehicle required flatbed towing to an authorized Genesis dealership for evaluation. A dealership service advisor subsequently informed me that the vehicle has been diagnosed with an ICCU failure, a component responsible for charging the 12-volt battery and maintaining critical electrical systems. Failure of this component can result in loss of drivability, propulsion limitations, or vehicle shutdown, creating a significant roadway safety hazard. Safety Concern Failures of the ICCU have been widely reported across Hyundai, Kia, and Genesis electric vehicles and have been the subject of prior recalls due to the potential for unexpected loss of motive power while driving. Despite prior recall actions, failures continue to occur, including in my vehicle. Current Status The vehicle remains out of service pending repair, and no written repair completion timeline has been provided. The failure rendered the vehicle unusable and required emergency towing. I respectfully request that the Office of Defects Investigation review continuing ICCU failures affecting Genesis, Hyundai, and Kia electric vehicles to determine whether additional corrective action or expanded remedies INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO

2024 Genesis GV70 Reno, NV

FUEL/PROPULSION SYSTEM

I moved my Genesis GV-70 to my home in Reno, NV. My complaint is in regard to my car becoming very dangerous! I'm giving you my move to Reno because its relevant to this complaint. I didn't need quick acceleration while I was living in Florida. In Reno, I have to merge onto Route 80 everywhere that I go. Acceleration during a merger is extremely important here in Reno. So what I've experienced in Reno is a VERY DANGEROUS situation with my Genesis. My GV-70 stops accelerating around 40MPH, or roughly 5,000 RPM. The transmission stalls out and the car revs at 5000 but does not respond. I've almost been rear ended by tractor trailers and other vehicles because of this dangerous situation. I have since found out that my recall for a ECM Software Update-P030X Misfire problem is the acceleration issue that I've described. Here is my complaint: My car should not be allowed to be driven in this current condition. Genesis has understated the severity of this issue dramatically and certainly the language in their recall letter didn't reference not being able to accelerate past 40 MPH/5,000 RPM. I didn't experience this issue while driving mostly local roads in Fort Myers Florida, but here in Reno, this car and it's condition is DANGEROUS! It has caused near misses with very catastrophic consequences. I am driving my car to Rocklin California (2 hours away) next week for service which includes the Misfire problem as well as other service issues. The Misfire recall should taken my car off the road, Genesis did not address the severity and dangerous possibilities of this issue.

2026 Genesis GV70 Round Rock, TX

FUEL/PROPULSION SYSTEM

While driving on the highway, the car shut down with no warning messages and gas fumes filled the interior of the car. I was not able to move over to a completely safe spot on the road because the car shut down so quickly. I was not able to put the windows down as there was no power to the car and unable to exit the car because I was not in a safe spot on the highway. I had to remain in the closed car inhaling the gas fumes. I called 911 and they had me sit in the sheriffs car until a tow truck came to keep me out of the fumes. The car was towed to the dealership, it had 53 miles on it. This event was extremely dangerous. It is currently at the service department of the dealership for repairs.

2022 Genesis GV70 Dunedin, FL

FUEL/PROPULSION SYSTEM

Started car. Would not accelerate past 30-40 miles an hour even when I pressed the Gas Pedal to the floor. I pulled over and turned the car off. On restart it seems to be fine. The Genesis GV 70 forum is replete with owners having the same issue. This is a 2022 with less than 25,000 miles on the Odometer. There are not many of these cars on the road and probably many owners are unaware that this seems to be a recurring issue on many of these models. I implore the NHTSA to look into this matter quickly before fatal accidents , if they haven’t occurred already, happen.

2023 Genesis GV70 Carolina Shores, NC

FUEL/PROPULSION SYSTEM

I purchased this vehicle brand new in July 2023. By Jan 2024, it was already having major issues. The 2 major issues with this vehicle are 1) it had an engine misfire ( thus engine and fuel system issues) that cut the power to the vehicle and made it dangerous to drive and thus had to be in at the Genesis dealer service center 3 times (Jan, April and May 2024). The 2nd problem is electrical. On Oct 1st, 2024 the brake lights wouldn't turn off at all despite several troubleshooting attempts. That electrical problem drained the battery and after the car was jump started, after I started to drive, then the car cold died in the middle of the road. I had my 10 day old newborn in the car and I had to get out and stop cars that were driving towards me. Attached is the repair invoice for the engine misfire earlier this year and the car is currently at the repair facility for the electrical problem so no invoice has been generated yet.

FUEL/PROPULSION SYSTEM

I had just started the car and driven less than half a mile in a 35 MPH zone when the acceleration gave out. Vehicle would not go over 20 MPH, engine did not rev up when gas pedal depressed. I came to red light and stopped, turned off the car and turned it back on and issue seemed to clear. I google and have learned this model and year are being recalled for this issue and fuel pumps replaced, but my VIN does not show up as under the recall. I'm now afraid to drive my car.

I was sitting at a stop light waiting to make a right turn. When I pressed down on the accelerator the car just inched forward. I let off the gas and pushed the accelerator again and again before the car would accelerate. This has happened several times, once almost causing me to wreck. This has happened since the first month I purchased the vehicle. I have had it for a year

FUEL/PROPULSION SYSTEM

[XXX] At approximately [XXX] pm, while driving to Dallas, Texas, the car bucked numerous times while attempting to pass another car at approximately 65 mph. The GV70 then started to deaccelerate. The speed dropped to around 50 mph. I continued to press the accelerator, but the car would not accelerate but the engine was revving (RPM hit around 5000) and then dropped back down. I continued driving with the speed varying between 45 and 55 mph even with the accelerator floored. As I got closer to Dallas, I could get the speed up to 60 - 65 mph with the accelerator floored but then on any incline, the speed would drop back to 45 - 50 mph. I had to turn the hazards on several times as the speed was well below the other vehicles. There were no warning lights. I was able to get the GV70 into a dealer the next morning who kept the car for 2 days. They ran diagnostics and drove the GV70 but could not replicate the problem nor did the diagnostics sow anything. They thought that maybe the car reset when it was turned off. Issue has occurred multiple times since initial occurrence. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
