Some new Tesla Cybertruck owners reported finding "orange rust marks" on their vehicles after exposure to rain, with instances documented in California where owners were informed by Tesla advisors that the marks require buffing out. Despite taking the issue to Tesla service facilities, the staff lacked the necessary tools and experience to address the corrosion. Tesla's manual acknowledges the Cybertruck's vulnerability to corrosive substances, but the company has yet to respond to these specific rust claims officially.
