The Song-Beverly Act’s replace-or-refund remedy applies only to unrepaired defects in new cars, which the Act defines to include dealer owned and demonstrator cars or other motor vehicles sold with a manufacturer’s new car warranty.  (Civ. Code 1793.22(e)(2).)  This decision holds that a car which was previously sold to another consumer is not a “new” car for these purposes even if the buyer succeeds to the unexpired portion of the express warranty that the manufacturer gave to the original buyer.
