My 2018 Model 3 (received in October) has 47K miles and peeling paint on both left and right rocker panel trim. Tesla says my problem, I have a gravel driveway and paint is not capable of withstanding the impact of the stone, did not realize the car was designed for driving on paved roads only. Interestingly, only the plastic trim is peeling, none of the metal parts are chipped or peeling. Wondering if others are having same issue, and recommended fixes, after I pay to have it re-painted.
