Products Liability Law Daily Wrap Up, DESIGN AND MANUFACTURING DEFECTS—MOTOR VEHICLES—E.D. Mich.: Class claims against Ford dismissed in vehicle owners’ engine valve defect case, (Mar 27, 2026)

By Pankhuri Bhatnagar, B.A. LL.B.

The suit was dismissed for lack of standing since the owners failed to establish the existence of a defect in their vehicles that would have caused their alleged economic injury.

In a putative class action brought against an automaker by individuals whose vehicle engines contained allegedly defective valves but fell outside the automakers’ recall period, a federal district court in Michigan granted the manufacturer’s motion to dismiss. The court found that the owners failed to show a design or manufacturing defect to sustain their overpayment theory because the valves only fractured during high temperature machining rather than during regular driving, their vehicles did not suffer an engine failure, a recall applicable to later vehicles did not establish a defect in their vehicles, and the claims amounted to a speculative risk of future harm rather than a concrete injury (Barkus v. Ford Motor Co., 2:24-CV-13310 (E.D. Mich. Mar. 23, 2026)).

Background. Three individuals brought a putative class action against Ford Motor Co., alleging that certain Ford vehicles equipped with 2.7L and 3.0L EcoBoost engines contained defective intake valves made from “Silchrome Lite,” a material which becomes hard and brittle when exposed to high temperatures during machining, leading to a valve fracture which causes sudden and catastrophic engine failure and loss of motive power. Ford identified 328 customer complaints, 487 warranty claims, and 809 engine exchanges relating to the 2.7 L EcoBoost engine, and the number of potentially affected vehicles was 708,837. Ford implemented a design and process modification in October 2021 by switching to a different alloy (Silchrome 1) and improving manufacturing controls. The claimants relied heavily on investigations conducted by the National Highway Traffic Safety Administration (NHTSA), which identified a concentration of engine failures in vehicles manufactured between May and October 2021, leading to a recall covering that “spike period.” However, the owners’ vehicles were manufactured before that period, were not included in the recall, and had not experienced any failure. They alleged that the manufacturer concealed the defect and that they overpaid for unsafe vehicles. The manufacturer moved to dismiss for lack of standing and failure to state a claim.

Legal standard. To establish Article III standing, the claimants were required to show that they (1) suffered an injury-in-fact; (2) fairly traceable to Ford’s challenged conduct; and (3) that was likely to be redressed by a favorable judicial decision. Spokeo, Inc. v. Robins, 578 U.S. 330, 338 (2016). An injury in fact exists if a plaintiff “suffered ‘an invasion of a legally protected interest’ that was ‘concrete and particularized’ and ‘actual or imminent, not conjectural or hypothetical.’” Lujan v. Defenders of Wildlife, 504 U.S. 555, 560 (1992). The Sixth Circuit has indicated that “a plaintiff can suffer a concrete injury when he or she overpays for a defective product” Speerly v. Gen. Motors, LLC, 143 F.4th 306, 314 (6th Cir. June 27, 2025) but they must “allege facts sufficient to raise a ‘plausible’ inference of” a defective product to establish their overpayment theory.

Design defect. The owners argued that the use of Silchrome Lite in the class vehicles’ intake valves constituted a defective design, since it was a compromised material which could not withstand pressure during the vehicles’ regular operation. They pointed to Ford’s decision to switch to a more resilient alloy that was less prone to fracture. Although the material was associated with failures, the NHTSA investigation showed that fractures occurred when valves were exposed to excessive temperatures during manufacturing, resulting in “grinding burn” and abnormal hardness, and not due to temperatures during regular driving. The court held that the owners’ claims were speculative as there was no proof that Silchrome Lite possessed a risk of failure outside a manufacturing error. The change from Silchrome Lite to Silchrome 1 could reflect ordinary product improvement or a response to manufacturing variability rather than an inherently unsafe design. The owners did not allege that all valves were subject to “over-temperature during machine grinding” or that all Silchrome Lite valves were “per se defective because of the inherent potential for malfunction due to its design.” Chapman v. Gen. Motors LLC, 531 F. Supp. 3d 1257, 1275 (E.D. Mich. Mar. 31, 2021). As such, a design defect was not plausibly pleaded.

Manufacturing defect. The owners alternatively suggested that a manufacturing defect caused valve failures, citing evidence that overheating during machining could make valves brittle and prone to fracture, and relied on the recall to allege that the valves in their own vehicles—manufactured before May 2021—were defective. The court acknowledged that the NHTSA investigation supported the existence of a manufacturing defect in some vehicles, particularly those produced during the spike period. However, a product recall alone does not raise a plausible inference that the product is defective. Ward v. J.M. Smucker Co., 2025 WL 2613489 (6th Cir. Sept. 10, 2025). The owners cited that Ford started receiving warranty claims and field reports of fractured valves months before the recalled vehicles were even manufactured. But due to overlapping timeframes, it was unclear how many of those reports were received before the spike period began. Even within the recalled population, only approximately 1% of vehicles were estimated to contain defective valves, so the defect rate among the broader population of vehicles using Silchrome Lite valves would be even lower. Assertions that additional failures would be revealed through discovery or that warranty claims exceeded reported complaints were speculative. Norman v. FCA US, LLC, 696 F. Supp. 3d 359, 368–69 (E.D. Mich. 2023). Thus, the allegations were insufficient to show that any defects were “sufficiently widespread” to affect the owners’ vehicles.

Overpayment. The court held that while economic injury from overpayment can constitute injury-in-fact, such theory requires plausible allegations that the product purchased was defective. Here, the owners did not experience any manifestation of the defect and relied on the existence of defects in other vehicles. Because they failed to plausibly plead a design or manufacturing defect in their own or the class vehicles, their claims reflected a speculative risk of future harm rather than a concrete injury and the case was dismissed for lack of Article III standing without addressing the remaining claims.

The case is No. 2:24-CV-13310.
