Hello all, I seem to have a whistle in my quad cab cabin at highway speeds. It seems when going 75-80 MPH it sounds like there may be a leak in the windshield or something. It's not super loud but definitely annoying. Thanks for any ideas, Nick.

 

If its not something easy.

Roll all your windows down then back up to make sure they are sealed.
Check sliding rear glass if you have it.

If a whistle can be heard each time you reach interstate speeds take it in for a fix.
Mine had bad weather stripping. The wind noise in mine was ridiculous at highway speeds. Several here complained...seach wind noise.

The dealer replaced the right side front door weather stripping and the right side mirror, cured my excessive wind noise issues.
Pretty sure it was the top of the weatherstripping that was not sealing correct...

I tried to find it myself over one weekend. Used painters tape.
That gap in the weatherstripping around the windscreen is suspect.
You look. There are two small gaps about where the mirrors are.

Bigger suspect is the weatherstripping from where the whistle is coming from.
Take you tech for a ride on the interstate. They fixed mine.

 

Wow, I am thinking I am glad I got a prior to Jan09 build date. Seems the problems are with the later models. Mine is like a Caddy or Lexus, you get in the door makes that nice solid chunk sound like any high quality vehicle and you can barely hear a sound outside, it has to be loud. My only real issue is the height of the truck and being paraplegic you might think what an *** for getting a truck you can barely get into. One I don't go out that often and 2 we have 3 other vehicles I can get into no issue. I put 2 12V scissor jacks under the wheel chair, bolted them in place and well it works but not alone. I cannot do it alone, but then again I only go out alone in my 72 chevy when I want to go tearing up the roads.

 

Did you ever figure out what the noise was I"m experiencing the same thing.
