Siqueiros v. General Motors LLC

Background

Plaintiffs alleged that General Motors knowingly manufactured and sold vehicles containing the Gen IV Vortec 5300 LC9 engine with an inherent oil-consumption defect. According to the allegations, improperly designed piston rings allowed oil to move into the combustion chamber, where it could burn or create carbon buildup. Plaintiffs alleged that the defect could cause inadequate lubrication, low oil pressure, spark-plug fouling, engine problems, and dangerous roadside breakdowns.

The proposed class was limited to vehicles with LC9 engines equipped with Active Fuel Management. The vehicles included specified 2010–2014 Chevrolet Avalanche, Silverado, Suburban, and Tahoe models, and GMC Sierra, Yukon, and Yukon XL models. Plaintiffs asserted claims under state consumer-protection, fraud, and warranty laws on behalf of nationwide and statewide classes.

Before this order, the court had certified four claims for class treatment: a California implied-warranty claim, an Idaho consumer-protection claim, a North Carolina implied-warranty claim, and a Texas implied-warranty claim. The pending motions sought to decertify all classes for lack of Article III standing and to decertify the North Carolina and Texas classes.

Article III Standing

Article III standing is the constitutional requirement that a plaintiff show a concrete injury that a court can address. General Motors argued that the Supreme Court’s decision in TransUnion LLC v. Ramirez required decertification because many class members had not experienced the alleged oil-consumption problems.

The court rejected that argument. It held that plaintiffs who purchased the allegedly defective vehicles suffered a concrete monetary injury when they overpaid for those vehicles, even if the defect had not caused noticeable effects in every vehicle. The court distinguished TransUnion, where the relevant class members had not shown that inaccurate credit-report information had been shared with third parties. Here, the alleged injury was the reduced value of the vehicles, not merely the risk of future engine problems.

The court also cited plaintiffs’ expert evidence that the alleged defect caused excessive piston-ring wear in all class vehicles, even though many class members had not experienced the defect’s effects. The court therefore denied General Motors’ motion to decertify all classes for lack of Article III standing.

North Carolina Class

The court considered whether North Carolina’s implied warranty of merchantability requires the alleged defect to manifest itself in each class member’s vehicle through excessive oil consumption, engine wear, personal injury, or property damage. The court explained that North Carolina law requires proof that the goods were defective when sold, that the defect caused the resulting injury, and that damages were suffered.

The court concluded that neither the North Carolina Supreme Court nor that state’s intermediate appellate courts had held that the defect must manifest as personal injury or property damage for an implied-warranty claim. The federal North Carolina decision cited by General Motors did not rely on North Carolina legal authority establishing such a requirement. The court therefore denied General Motors’ motion to decertify the North Carolina class.

Texas Class

The court reached a different conclusion under Texas law. It explained that Texas implied-warranty law requires a product to be unfit for its ordinary purpose, the defect to exist when the product left the manufacturer’s possession, and the defect to cause injury.

The court relied on Texas appellate decisions holding that an implied-warranty defect must manifest during normal use, or manifestation must be inevitable, and that a vehicle’s mere purchase with an alleged defect is not enough. Those decisions required the defect to disrupt vehicle operation so that the vehicle was unfit for safely moving people from one place to another.

Because the alleged oil-consumption defect had not disrupted the operation of all Texas class members’ vehicles, the court held that class certification was inappropriate under Texas law. It therefore granted General Motors’ motion to decertify the Texas class.

Disposition

The order states that the court (1) denies the motion to decertify for lack of Article III standing, (2) denies the motion to decertify the North Carolina class, and (3) grants the motion to decertify the Texas class. The order disposes of Docket Nos. 325 and 347.
