Genesis GV80 collision warning problems

Filed Oct 19, 2026 · Driver assistance, Electrical · DE · fire

Description of Safety Defect & Incident Sequence Severe moisture intrusion inside the driver-side headlight assembly triggered a sudden cascade of critical safety sensor failures while driving, followed by an active electrical short, component melting, and smoke (fire hazard) after the vehicle was shut off. While driving, a dangerous cascade of electrical and safety sensor failures suddenly occurred. Multiple critical dashboard warning alerts triggered simultaneously, including: Turn Signal Out, Blind Spot Warning, Lane Departure Warning, Rear Cross Traffic Warning, Forward Collision Warning, and Speed Control. Upon parking and exiting the vehicle, the driver-side headlight housing was found completely obscured by severe internal condensation. Despite the vehicle being turned off and the ignition key removed, the turn signal bulb remained actively flickering, indicating a severe, uncontrolled electrical short circuit. Upon opening the hood, a strong odor of burning plastic/rubber was present, and an active trail of smoke was visibly emanating directly from the headlight assembly area. To prevent an imminent vehicle fire, the main headlight fuse had to be immediately located and pulled. This defect represents a critical safety hazard, causing a sudden loss of advanced driver assistance systems (ADAS) while driving and a severe electrical fire risk while parked. This is a known issue by Genesis under "Genesis Technical Service Bulletin TSB 23-BD-002G"

The headlight assemblies on both the right and left side have water pooling which severely dims nighttime visibility and creates an immediate risk of total headlight failure while driving at highway speeds. The Forward Collision Avoidance safety sensors have begun flashing or malfunctioning due to the excessive moisture.

Purchased CPO 2/28/24. Water intrusion defect manifested 5/28/24 (3 months) with electrical failures and dampness odor. Active leak discovered 9/25 - water leaked onto passenger during operation. CHILD HEALTH EMERGENCY: My daughter required THREE emergency room visits for severe allergic reactions after riding in vehicle - suspected mold/biological contamination from water intrusion. MANUFACTURER RESPONSE: Vehicle out of service 139 DAYS for warranty repairs (11/1-12/6/25: 35 days; 12/18/25-4/1/26: 104 days). Genesis inspection 1/19/26 but REFUSED to provide report claiming "attorney-client privilege." Genesis denied buyback 2/13/26. CURRENT CRITICAL SAFETY ISSUE: Vehicle returned 4/1/26. Passenger side view mirror now non-functional (safety hazard for lane changes/merging). WATER LEAK HAS RETURNED - same leak, same dampness odor. The "permanent repair" FAILED after only 2 weeks. Dealership REFUSING all repairs. 12/18/25 INCIDENT: While driving in rain, multiple safety system warnings illuminated simultaneously (forward collision warning, stability alerts) - suspected water damage to electrical systems. SYSTEMIC DEFECT CONCERN: Online research shows MULTIPLE 2021-2024 Genesis GV80 owners reporting identical water intrusion from sunroof drainage system failures. This appears to be manufacturing/design defect affecting many vehicles. REQUESTING: 1. Safety investigation of 2021-2024 Genesis GV80 sunroof drainage systems 2. Potential recall for water intrusion defect 3. Investigation of health hazards from mold/contamination 4. Investigation of manufacturer concealing defect inspection findings DANGER: Water intrusion causing electrical failures creates fire risk, safety system failures, and biological contamination health hazards. Children at highest risk for mold exposure injuries.

The Forward Collision Warning in my GV80 activated unnecessarily, which resulted in the car to break without need / warning, this resulted in the GV80 being hit from behind, the GV80 was pushed forward into another vehicle. The vehicle is unsafe for driving and has remained parked. The Forward Collision Warning activated when it was not needed and caused a rear-end accident which was quite impactful since we were not expecting a collision. The GV80 was inspected by an independent service and could not be proved to be at fault. It was deemed to "operate as designed" in spite of our experience and now even though there is damage to one of the front end sensors from the accident. The dealership claimed the GV80 needs $8000 worth of repairs as a result of the rear end incident. I did experience unnecessary collision alerts a week before the collision, when I realized this was faulty, I called the dealership and they explained that there was a setting that was at fault that I NEEDED TO CORRECT in the Settings AND, that they had been receiving others reports of the same problem "three times already today." This setting needed to be reset upon each time I started the car and they explained I also needed to wipe clean all sensors before driving in inclement weather. I experienced 3 more unnecessary Collision Breaking incidents in a single 2 mile driving range and dropped the car off at the dealership as I felt very unsafe to continue operating the GV80.

1. When starting from a stop the vehicle sometimes applies brakes with a collision warning, with no other vehicles in front or next to the car. This will repeat several times before the issue goes away. This has happened 4 times in the last 10 days. Â 2. When using adaptive cruise control the vehicle will not recognize vehicles ahead, even with the maximum following distance selected. This is almost always the case.

i was driving down the freeway and the computer system had a complete reboot randomly. ALL screens went blank and ALL electronic functions were disabled until it came back up about a minute later. No radio, no ADAS features (no collision warning, no blind spot, no lane departure), no gauges to to judge speed. It was a complete distraction. Vehicle appeared to continue to drive but without any safety features. It is unknown if turn signals and day time running lights and air bag functions were disabled. I noticed issued after they applied an update for Android Auto with the maps not showing in the display even tho voice instructions came through the car. It was either a system update that should have never happened while the vehicle is in use, or I suspect an issue with Android Auto that caused the vehicle OS to crash and reboot.

The electrical wiring harnesses affecting numerous safety systems (forward collision warning, automatic emergency braking, lane departure warning) have been chewed through by rodents. Upon further research it was determined that starting in 2016 Asian automotive manufacturers (Nissan, Toyota, Kia, Hyundai) began using soy-based insulation in their wiring harnesses as alternatives to petroleum-based insulation. Rodents (mice, squirrels, etc.) are attracted to the wiring harnesses. The resultant damage and safety concerns led customers to file several lawsuits against the manufacturers. It is not clear whether Hyundai stopped the use of these soy-based wiring harnesses after 2021. Genesis is a spin-off of Hyundai, leveraging common parts. It appears that these soy-based wiring harnesses are being used in some of the 2022 GV80 models. Genesis currently burdens its customers with the cost to troubleshoot and replace these harnesses. Given the previous lawsuits and the continue risks of using these wiring harnesses in key safety systems, it is recommended that Hyundai and Genesis issue manufacturer recalls to ensure these harnesses are replaced with materials that do not attract rodents. We first started experiencing intermittent failures in in the highway driving assist system. Then, forward collision warning and lane departure warning systems. These became more pronounced until we brought the vehicle into Pearson Genesis of Richmond on 06/28/2024. After troubleshooting and inspecting the automobile, the technician showed us pictures of where rodents had eaten through wiring harnesses (attached). The cost to repair this over two visits totaled $957.42. I contacted Genesis headquarters suggesting they investigate this further, given the lawsuits. They agreed to offset my cost by $672, but did not agree to address the underlying problem.

While driving at low speeds (less than 50mph) the Forward Collision Warning randomly activates. Sometimes its just a warning and sometimes its a warning and forced braking. I was able to capture a video of this. Please see link below. The first occurrence was in November 2023 after I the I took it to the dealership to address Recall Number: [XXX] 2022MY GV70, 2021-22MY GV80, 2021-22MY G80 LOW-PRESSURE FUEL.

Forward collision warning and active assist are practically inoperable. The vehicle doesn't detect the car in front of it and doesn't show it on display. The operation doesn't match the described function in the owner's manual. After trying to work with Genesis Corporate office and dealer, I could replicate the problem during the test drive that was conducted after dealer performed extensive diagnostics together with Genesis tech support. System didn't return any fault codes. Dealer documented the issue in the service record. During the test drive, the WARNING system finally activated when collision would have been imminent only prevented from the accident by the technician driving by slamming on the brakes. The emergency braking system didn't activate at all. I drove various loaner cars being Genesis 2023 models that all exhibited the same behavior. According to the manual the system should be active at the speeds 6 miles per hour or above. I can get very close to the car in front of me and nothing would happen. It only affects normal driving. Adaptive cruise control works fine and sees the vehicle in front of me with no issues
