Following Duale v. Mercedes-Benz USA, LLC (2007) 148 Cal.App.4th 718, this decision holds that a valid and reasonable section 998 offer by the seller, where the buyer recovers less than the offer, precludes recovery by the buyer of post-offer attorneys’ fees and costs under Code of Civil Procedure section 1794(d) of the Song-Beverly Warranty Act claim.  Here, the defendant’s initial offer was valid even though it did not address post-acceptance attorney fees, pre- and post-judgment interest, whether a separate release would be required, a specific date for payment or for surrender of the vehicle.  However, the defendant’s first 998 offer might not have been “in good faith” or effective because it was made only 63 days after the complaint was filed–before the plaintiff had time to conduct discovery to evaluate his case.  On remand, the trial court must decide that issue.
