Second, “[i]f the answer to the first question is in the negative, did the plaintiff present a prima facie case under the ‘malfunction theory’ of products liability?” Id. at 950, 60 A.3d 741. Because we agree with the Appellate Court that the plaintiff did not preserve his malfunction theory claim for appellate review, we answer the first certified question in the affirmative and do not reach the merits of the plaintiff's claim under the second certified question. Accordingly, we affirm the judgment of the Appellate Court.
