Engine Defects

Navistar Truck

Navistar International Corporation and Navistar, Inc. have agreed to settle a class action about their 2011-2014 trucks equipped with MaxxForce 11- or 13-liter diesel engines. The complaint alleged that the trucks had defective exhaust gas recirculation (EGR) emissions systems that produced more soot and heat than engine components could handle, leading to failure of the components.

2017 Subaru WRX STi

Subaru of America, Inc. and Subaru Corporation are settling a class action alleging that some of its model year 2012 to 2017 Imprezas have defective engine bearings. The complaint alleges that the bearing can cause premature failure of connecting rods and main bearings, and that selling the cars with this defect breaches warranties and violates consumer protection laws.

2016 Kia Soul

What would you do if your car suddenly stalled on a highway or burst into flames? The complaint for this class action alleges that certain models of Hyundai and Kia vehicles with gasoline direct-injection (GDI) engines have serious defects that the companies have concealed. The defects allegedly cause the vehicles to stall while at speed or catch fire. The complaint alleges fraud by concealment and breaches of warranties, among other things.

2018 Honda Civic

When Honda announced its new VTEC Turbo direct-injection engine in 2013, it touted it as a next-generation powertrain technology that provides a high level of fuel economy. But the complaint for this class action claims that it has a serious flaw: It allows fuel to migrate and mix with the oil, lowering the oil’s viscosity, increasing friction, and eventually possibly damaging the engine. 

PACCAR Peterbilt Truck

The complaint for this class action claims that PACCAR engines are inherently defective and repeatedly fail, causing danger to the drivers of its trucks and to other motorists on the road. According to the complaint, the only remedy PACCAR has for its engine problems is the replacement of defective parts with equally defective parts that are destined to fail in their turn. The complaint alleges breaches of warranties, among other things. 

2017 Hyundai Sonata

Plaintiff Andrea Smolek says she was driving on the highway when she heard loud sounds from the engine area of her Kia Sorrento. Then came a loud bang, she claims, her vehicle shook violently, and the Check Engine light came on. Smolek was able to safely pull over and have her vehicle towed for repair, but the complaint for this class action claims that the problem was due to a defect in the car’s Theta II engine that allows contaminants to enter, thickens the oil to sludge, and eventually ruins the engine.

2017 Chevrolet Equinox

If your car engine is consuming oil faster than it should, how would you know when more oil is needed? Perhaps you would rely on the vehicle’s oil pressure warning (OPW) or oil life monitoring (OLM) system. But if you had a Chevrolet Equinox from certain model years, the complaint for this class action alleges, your engine could suffer damage or even shut down on the road before either of these systems gave you a warning. The complaint alleges breaches of warranties, among other violations.

2016 Kia Optima EX

Connor Brogan was driving in the highway in his 2016 Kia Optima EX when his engine made an odd noise, the complaint for this class action alleges—and then the car stopped and the engine caught fire. The complaint claims that Kia and Hyundai Theta II engines in certain model vehicles have a defect that can restrict oil flow and prevent proper lubrication that can result in engine failure, and that the companies have concealed this defect and continued to sell vehicles with affected engines.

The plaintiffs in this lawsuit allege that certain Hyundai Sonatas suffer from a defect that can cause engine seizure, stalling, engine noise, and oil light illumination. The plaintiffs also allege that engine seizure or stalling can be dangerous if experienced. The plaintiffs also allege that some owners and lessees have been improperly denied repairs under the vehicle’s warranty.
