Thanks for your response. It's similar to the sound of a subwoofer, but I removed the subwoofer and the sound is still there.
My brand new 2024 GT convertible (700 miles) has a resonance - type sound at 55 MPH that resembles the sound from a sub woofer. I removed the sub woofer, and it's still there. Will go back to the dealer with this, but not hopeful. Exhaust resonance? It doesn't have active valve exhaust.
My wife's Chrysler 300C has an underbody panel that has to be removed for oil changes. It has 4 screws. 15 screws and 4 push pins is unbelievable. I think Ford needs to hire a maintainability engineer.
