Complaint Summary

Owner Narrative
Severe recurring roof water intrusion on 2022 GMC HUMMER EV; repeated failed repairs; interior rust/corrosion; safety concerns in highâvoltage EV. Vehicle: 2022 GMC HUMMER EV Edition 1â¨VIN: [XXX] Current mileage: ~12,000 miles⨠â¨My vehicle has a recurring defect involving severe water intrusion into the cabin through/around the removable roof panels/roof sealing areas during rain. Despite repeated dealership repair attempts, the vehicle continues to leak. The ongoing water intrusion has caused visible corrosion (rust) on interior metal structures, including the floor area and seat rails/seat mounting areas. The corrosion indicates prolonged moisture exposure inside the cabin. The dealership has attempted to repair this water intrusion issue approximately six (6) separate times, and the defect remains unresolved. First documented repair attempt: 03/14/2023 (issue presented to dealership for correction) Most recent repair attempt/out-of-service: 12/29/2025 to 01/06/2026â¨The vehicle has spent weeks at the dealership across these attempts, including time waiting for parts and work completion. Even after these repairs, the vehicle is still leaking and the corrosion is still present. â¨Because this is a highâvoltage electric vehicle, I am concerned that water ingress and corrosion are compromising electrical wiring/connectors and safety systems located in/near the cabin floor and seat areas (including areas where sensors and connectors may be present). I am concerned this could increase the risk of electrical short, malfunction of safety systems (including airbag sensors), and in a worst case scenario a fire risk if moisture reaches sensitive electrical components. I can provide photos/videos of active water intrusion and corrosion and all repair orders upon request. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
