Thumping Noise

[kamb1950]

We have a 2014 Sunseeker . We have 32,000 miles on it . Just recently we have developed a loud thumping noise that seems to be coming from behind the vent directly below the oven . We have checked everything we can think of - secured all items in bins, etc. It has gotten so annoying that we even sliced off the mudflap ! Nothing helps !
Any ideas ?

It could be the flap for the vent that goes to the outside. Go outside and make sure it is secured properly. It should snap in place.

i had to put a piece of paper towel between the vent flap to keep it from making noise

If this is a thumping when moving check for a bulge on one of your tires. If sitting still, what are you using when it makes the thumping sound.

It starts at 65 mph. Taking it to a dealer tomorrow. Can't figure it out. Thanks!
