Owner report 11678598 · 2025-08-05 (August 5, 2025)
Vehicle stalled out on major highway in 2023, 2024 and 2025. In 2023 and 2024 had vehicle towed to dealership and they could not recreate issue. Then in July 2025 vehicle stalled out and would not start again in major highway and towed again to dealership and they said it was fuel pump issue. This is what should have been detected in 2023 and 2024. I can’t trust the dealer they they will actually fix my vehicle.
