Peg Perego Primo Viaggio - tilt indicator noise ?

OK, about 2 weeks (or less) before delivery day of our #1. "Houston, all systems are GO" as the astronauts might say.

Yesterday we had the car seat installed and inspected by local firefighters (as part of the auto club/provincial insurance child safety program). All was good. But after spending a day driving around with the seat base I realized the built-in tilt leveler indicator allows the metal ball to vibrate inside the indicator chamber and it's constantly making a soft but annoying buzzing noise.

Just wondering if anyone else has had this problem with the Viaggio ?

Thanks.
