N.Y. Comp. Codes R. & Regs. tit. 15 § 78.14
Any guarantee or warranty given by a dealer with respect to any vehicle must be in writing and a copy delivered to the purchaser thereof. Such guarantee or warranty must contain the scope of guarantee or warranty, the limitations as to date or mileage, and the specific terms and items covered thereby. The guarantee or warranty must be signed by the dealer or authorized representative. Warranties issued by corporations, companies or individuals, other than factory warranties or those issued directly by a dealer, shall not be sold or given to the purchaser of a motor vehicle by the dealer, either directly or indirectly, unless such corporation, company or individual is duly authorized to issue such warranties pursuant to section 41 of the Insurance Law of the State of New York. A dealer, before selling a new car that has less than the full new car warranty, must inform the purchaser in writing how many months are left on the new car warranty. Such remaining warranty period shall be typed, printed or written on the bill of sale or invoice in a conspicuous manner and apart from other printing or information on the document.
