When a manufacturer cannot repair a new car to cure a defect after a reasonable number of attempts to do so, it must either give the buyer a replacement car or pay the buyer restitution of the full purchase price plus collateral charges and incidental damages. Civ. Code 1793.2(d). Initial registration fees payable on purchase or lease of a new car are collateral charges that the manufacturer must pay, but, absent unusual circumstances, later annual renewal or nonoperation fees are not. Those fees may be recoverable by the buyer as incidental damages, but again absent unusual circumstances only if the buyer shows he paid the fee after the manufacturer’s obligation to provide a replacement or restitution arose.
