FWIW, both of mine (new Heavy Pacifics) ,different road names and from different dealers, had LED light issues from some seriously bad QC.
And then it's now the middle of December, and they still haven't said a peep about the sound files.
I had not noticed loose driveshafts/flywheels, but I don't yet have a lot of runtime on them (both did run and pull cars at my local club).
