Proceedings: FINDINGS OF FACT AND CONCLUSIONS OF LAW

I. Introduction On May 19, 2026, the Court held a bench trial in this case. Having carefully considered the evidence presented at trial, for the following reasons, the Court finds that Plaintiff Sarkis Demerjian (“Plaintiff”) has not met his burden to establish that Defendant Mercedes-Benz USA (“Defendant”) is liable for violations of the Song-Beverly Act. The Court therefore finds in favor of Defendant. II. Relevant Background The case arises out of alleged defects with a 2023 Mercedes-Benz E53 AMG, Vehicle Identification Number W1K1J6BB1PF193419 (the “Subject Vehicle”), purchased by Plaintiff on May 22, 2023. On April 2, 2025, Plaintiff filed suit in this Court, alleging a single cause of action for Defendant’s willful violation of the Song-Beverly Consumer Warranty Act (“SBCWA”) and requesting relief in the form of contract rescission, restitution, compensatory damages, civil penalties, and attorneys’ fees. Complaint, ECF No. 1.

In its Memorandum of Contentions of Fact and Law, submitted before trial, Plaintiff asserted the following “claims” against Defendant: (1) violation of the SBCWA, Cal. Civ. Code § 1793.2(d)(2), for

Title Sarkis Demerjian v. Mercedes-Benz USA LLC et al JS-6 failure to conform the Subject Vehicle to express warranty after a reasonable number of attempts; (2) violation of the SBCWA, Cal. Civ. Code § 1793.2(b), for failure to commence repairs within a reasonable time or conform goods to the applicable warranties within 30 days; (3) violation of the implied warranty of fitness and merchantability; (4) violation of express warranty; (5) a judicial finding that Plaintiff was entitled to the “Tanner Act presumption” regarding reasonable repair attempts; (6) a judicial finding that Plaintiff is entitled to enforcement of a certified Better Business Bureau (“BBB”) arbitration decision requiring repurchase; and (7) a civil penalty. ECF No. 48 at 1.

At trial, the Court received evidence from both parties. The Court also received direct testimony in the form of signed declarations from four witnesses: (1) Plaintiff, (2) Plaintiff’s expert, Randall Bounds, (3) Defendant’s expert, Clark Bauman, and (4) Defendant’s Rule 30(b)(6) corporate designee, Nicholas Cinquepalmi. At trial, each of these witnesses was subjected to thorough cross and re-direct examination by both parties. III. Findings of Fact and Law Plaintiff asserted three cognizable claims at trial: (1) failure to timely replace the Subject Vehicle or make restitution pursuant to California Civil Code § 1793.2(d); (2) failure to commence repairs of the vehicle within a reasonable time and repair the vehicle to conform with the applicable warranties within thirty days pursuant to California Civil Code § 1793.2(b); and breach of the implied warranty of merchantability pursuant to California Civil Code §§ 1791.1, 1794, and 1795.5. A. First Cause of Action: Failure to Timely Replace Under the first cause of action under Cal. Civil Code § 1793.2(d), for a plaintiff to establish that a manufacturer failed to promptly repurchase or replace a new motor vehicle after a reasonable number of repair opportunities, the following elements must be met: (1) the vehicle had a nonconformity covered by the express warranty that substantially impaired the use, value or safety of the vehicle; (2) the vehicle was presented to an authorized representative of the manufacturer of the vehicle for repair; and (3) the

As a preliminary matter, the Court considers the persuasive weight of the BBB Arbitration Award. After all, the BBB Arbitrator did find the presence of a substantially impairing nonconformity, reasonable repair attempts, and a failure to repair. Exhibit 26. However, the evidence shows that this arbitration decision was non-adversarial and telephonic. The arbitrator did not consider expert testimony and could not view the video and photographic evidence. In that context, the Court finds that the findings of the arbitrator are not entitled to any substantial weight in this adversarial setting where the Court is able to hear argument from Defendant, solicit the opinions of experts, and observe Plaintiff’s live testimony to independently judge his credibility. The Court therefore conducts its own analysis for each element. i. The Nonconformity Element At trial, Plaintiff put forward evidence of four alleged defects with the vehicle: (1) the Subject Vehicle autonomously applied the brakes for no discernable reason (“phantom braking”), (2) the Subject Vehicle intermittently displayed a warning symbol on the dashboard, (3) the “active lane assist” feature intermittently malfunctioned, and (4) the Subject Vehicle had an oil leak from the front differential.

In determining whether Plaintiff has offered sufficient evidence of a nonconformity, the Court considers both whether there is perceptible evidence of a defect and also the probability that any perceived defects might have other explanations besides a nonconformity—such as environmental factors. For example, the evidence at trial showed that Plaintiff modified the Subject Vehicle shortly after he purchased it and before any repair attempts by tinting his windows and applying a film protection. Exhibit 7; Exhibit 115. Since the features of the Subject Vehicle exhibiting alleged defects relied on various sensors and cameras on the front of the vehicle, the rear of the vehicle, and behind the windshield, Plaintiff’s intervention with third party products to modify the windows and body of the vehicle may be alternative explanations for intermittent failures to function, if any existed. With this and other considerations in mind, the Court addresses each alleged nonconformity in turn and finds that the only substantial nonconformity established by the evidence was an oil leak from the front differential.

Title Sarkis Demerjian v. Mercedes-Benz USA LLC et al JS-6 a. Phantom Braking The alleged “phantom braking” defect is generally uncorroborated by evidence. According to the repair orders, Plaintiff sought repair for this alleged defect only once, on September 13, 2024. Exhibit 16. The notes from that repair attempt show that the dealership could not duplicate the alleged defect, even after a test drive. Moreover, even by the time of a subsequent repair order the following month, and in all future repair orders, the service notes, which Plaintiff concedes he reviewed and signed, make no reference to a complaint about ongoing phantom braking. Exhibit 17.
