Mine had that exact same problem last year, had SC retorque the front bash plates, and then it went away.
But then, a few month ago, that same issue returned. I took it to the SC and ask them to do the same again - they said they did (though I am not 100% sure) - but the issue remains.
I then took it to a mechanics friend of mine's place, took down the aero shields, and checked torque settings on the front bash plate - it's all up to specs, according to the manual.
I even over torqued a bit the bolts that attach the skid plate to the body sills. But it seems to make the problem slightly worse? Regardless, the popping sound is still there... I do reckon that it's a bit better than when I had it last year, where it was loud and obvious every time I turn the steering wheel.
But the more I think about it, over-torquing should NOT be the issue, as judging by the fact that the issue returned this year, and if anything, the bolt would not naturally overtighten itself.
So my own hypothesis that fits all the data points above is perhaps we need to over torque all bolts beyond the specs, as I suspected that's what SC did the first time.
