TPMS issue. Check your pressures.

 

Any warning lights on in the dash cluster?

 

I got that sound once when I left the snow mode on while driving on dry pavement. Smart car. . .

 

the car doesn't have tpms sensors, no warning lights and only does the noise at random.

 

What model car are we talking here?

 

03 g35 sedan automatic....
