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.

Left LED Headlamps & intergral camera sensor assembly has failed due to moisture penetration behind the lenses. In addition to no left headlamps or left front turn signal, we have lost the emergency braking, forward collision warning, the lane departure warning and the lane keeping assistance features. Service advisor has advised on 01/08/24 that this is a common problem & parts are not readily available.

The infotainment system on my GV80 works for 5 minutes and shuts down. The lane change warning light and front collision warning goes on and off while driving. the back-up camera and warning stopped working. When you park the vehicle, it takes at least it takes 10 minutes to completely shut down

Genesis GV80 2.5 T standard option Forward collision warning software problem. These vehicles are sold with this option but not showing on settings, therefore it is not usable. Similar complaints are known with 21 model G80, GV80, G90. I believe this problem is recorded as T17G.
