NO Law requires you to record / pledge your private automobile. a Private automobile is not required by any law, code or statute to be recorded. Any recording (pledge) of Private automobile to any agency is strictly voluntary. Any recordation / contract you or a Dealership has done was a fraudulently conveyed act as the recording agency/automobile Dealer told you that you must record your Private Property. The voluntary pledge that was done without just compensation is usually done through fraud, deceit, coercion and withholding of facts, which can only be construed as fraud and unjust enrichment by agency as well as a willful malicious act to unjustly enrich the recording agency and its public servants.
"Under the color of law" refers to actions taken by government Officials or Agents that appear to be within the bounds of their lawful authority but are, in fact, abuses of power or violations of an private citizen/non-citizen national‘s constitutional rights.
