Crazy Rattle behind firewall

[TrustWonUSA]

Picked up a 2025 Heritage this past weekend. Once we got on the interstate we heard a rattling going on. The rattle is coming from the front of the vehicle and most of the time sounds like the passenger side to center near the firewall area. I thought it was the windshield washer lines because they make a similar sounds when tapped on. I used some clothe electrical tape and did not change anything. Then I thought maybe the hood prop, so I put some cloth tape on it and it fit’s snuggly now but I still have this rattle.



i know I can take it to a dealer but I do not have hours upon hours to sit there and wait on it.



Any ideas would be greatly appreciated it

You will almost certainly have to take it to a service center. You can limit the amount of time they spend troubleshooting by collecting as much information as possible.

• Make sure it's not coming from inside the car. Noise bounces around a lot inside cars, especially off windows. Have someone touch every panel (dash, doors, roof, A-pillars, screens, etc.) inside the car when you hear the rattle to see if you can make stop.
• Describe the conditions under which the rattle occurs (acceleration/deceleration, braking, throttle open/closed, cruising, speeds, etc.).
• Try as much as possible to pinpoint the location.
