A new WRX STI engine failure lawsuit says Subaru has known about the defect since 2008

The American Subaru and the Subaru Corporation were subjected to another lawsuit related to the failure of the Subaru WRX and WRX engines. This week, a new lawsuit filed in New Jersey claims Subaru knew of an engine defect since 2008 in the EJ25 2.5-liter and FA20 2.0-liter turbocharged engines used on the 2009-2018 WRX and STI. This is another lawsuit against Subaru for performance car engine failure.

A new report from Top Class Actions says four plaintiffs, Ricardo Aquino, George Crumpker, Jonathan Piperato and Stephen Trescoe Allan, claim their WRX and WRX STI engines failed before they hit 80,000 miles. They are represented by attorneys Kantrowitz, Goldhamer & Graifman, PC, and Thomas P. Sobran, PC

The class action alleges that US Subaru and Subaru Corporation hid a defect in the engines’ piston ring grounds, causing the engines to fail much earlier than they are supposed to.

The lawsuit against the Japanese automaker alleges that the failure of the turbocharger engine was caused by a faulty piston ring, which resulted in sudden power loss and stalling, posing a “serious safety problem during vehicle operation.”

Another problem with the EJ25’s 2.5-liter and FA20 2.0-liter turbocharged engines stems from an “improper PCV system” that causes pre-ignition or detonation, “two known causes of internal engine component damage,” according to the lawsuit.

The class action says Subaru “knew or should have known no later than early 2008” of engine defects due to “significant field inspections, testing and quality audits of the vehicles.” The report from Top Class Actions says Subaru would have also known about the defect from warranty claims, communications on vehicle forums, and the National Highway Traffic Safety Administration’s database of consumer complaints.

The Subaru WRX or WRX STI engine was replaced for all four claimants due to a piston ring ground defect. The report says the class action against Subaru represents statewide subcategories of Illinois, Colorado, California, and New York current, former owners and renters of the 2009-2018 WRX and STI performance vehicles.

The lawsuit covers all 2009-2018 WRX and STI owners who purchased or leased their vehicles in the four states and “the ongoing financial loss and diminishing value of class vehicles resulting from the defect.”

The four plaintiffs are seeking “compensation, interest, pre-judgment interest, attorneys’ fees, reimbursement for all related engine repairs incurred by the class, and reimbursement of incidental expenses (such as rental vehicles and other alternative transportation)” incurred by Subaru WRX and WRX STI owners.

What should WRX and WRX STI owners do?

If you experience an engine failure with your 2009-2018 Subaru WRX or WRX STI and receive an estimate or pay for repair or engine rebuilding, you may be entitled to compensation if the situation resolves. If you believe you are a potential class member and have an engine defect, you may contact attorneys Kantrowitz, Goldhamer & Graifman, PC or Thomas P. Sobran, PC
