Noise from behind Drivers Head. Sounds like loose bolt driving down road, Suspect Top problem because noise goes away when top down.

Haven't had that issue. I'd suggest letting the dealer look at it. That's what the warranty is for.

Does the noise go away with just the rear window down?

Been to dealer for a day , took back 2nd time for a day. This time took in Wednesday and I'm going to pick it up this evening ar service dept closing, fixed or not. Will call GM assistance Monday to see next step. Qualifies Lemon Law but I love my Yellow LT3.

Try a different dealer?

As someone above posted, try driving with top up and rear window down. If the noise goes away, you have your culprit. I think I remember an old post discussing having to put some lubricant on the edge of the rear window to keep it from rattling.

Other than getting a louder exhaust or radio… maybe try to get a friend to drive and use an automotive stethoscope with and without an open tube to narrow it down to an area or a panel, mechanism. It could be a harmonic caused by wind buffeting only at certain speeds which is even more annoying. With the complexity and ability to govern you speed that this top mechanism has, I would not ignore it and would not go to the dealer again without some new information.

Don't forget the snap on the little buckle that holds your seat belt. At the top of the seat.

Driving with the top up I had that rattle. Top down it was gone....

Took it to the dealer and it was fixed the same day. Apparently it was a fastener that came lose in the bulkhead of the folding top.

Problem solved..... (You need a different dealer.)
