Subaru WRX And STI Engine Failure Lawsuit - A New Ruling Says It’s Not Over Yet

The Subaru WRX and WRX STI engine failure lawsuit is not over yet. Check out the new ruling and how it affects 2009-2018 Subaru WRX and WRX STI owners.

If you own a 2009 through 2018 Subaru WRX or Subaru WRX STI performance sports car, a new ruling in the Subaru WRX and WRX STI engine failure lawsuit by Judge Joseph H. Rodriguez for the U.S. District Court for the District of New Jersey, denies Subaru of America's motion to dismiss. Here is how it affects WRX and WRX STI owners.

A new report from Bloomberg Law (by subscription) says plaintiff Joseph Amato, represented by attorneys Kantrowitz, Goldhamer & Graifman, P.C., says Subaru WRX and WRX STI have defective ringlands around the pistons in the EJ25 2.5-liter turbocharged Boxer engines.

The class-action contends WRX and STI containing a ringlands defect experience a sudden loss of power or stalling that severely compromises the owner's ability to maintain vehicle control. The defective class engine components and engine management system also can cause sudden and catastrophic engine destruction as overheated internal parts seize.

History of the case

Subaru WRX and WRX STI owners contended in the lawsuit in 2017, the 2.5-liter turbocharged engine had a defect that allowed contaminated oil to carry "damaging metal debris through the engines," and Subaru knowingly sold the cars with defective parts that led to engine failure. The lawsuit said, "Plaintiffs alleged that Subaru was aware of this engine defect, but failed to disclose it to consumers."

A settlement was reached with Subaru of America in 2018 "following months of negotiations and discovery." Owners who filed the lawsuit asked the New Jersey federal judge to approve a settlement that included reimbursement for certain out-of-pocket repairs and compensation to those who sold or traded in their vehicles.

The current lawsuit

The New Jersey court addressed disputed legal questions about economic-loss claims under Pennsylvania's consumer law and claims on behalf of a proposed class under Georgia's Fair Business Practices Act.

A new plaintiff, Andrew Hinshaw from Michigan, claims the owner's manual in his Subaru WRX, purchased from a third party, contained misleading information using incorrect engine maintenance and service recommendations.

The lawsuit alleges, "The owner's manual and warranty and maintenance booklet materials accompanying class vehicles do not contain any maintenance or service information for defective class engine pistons or piston ringlands."

Judge Joseph H. Rodriguez said last week, each of those claims may now proceed. The New Jersey court will permit the plaintiffs to file a second amended lawsuit that includes plaintiff Hinshaw's negligent misrepresentation claim only.

What should WRX and WRX STI owners do?

If you have experienced engine failure with your 2009 - 2018 Subaru WRX or WRX STI and have received an estimate or have paid for the repair or engine rebuild, you may be entitled to compensation in the event this case resolves. If you believe you are a potential class member and have an engine defect, you can contact Gary S. Graifman, Kantrowitz, Goldhamer & Graifman.

This is the mesothelioma of automotive lawsuits. "The owner's manual and warranty and maintenance booklet materials accompanying class vehicles do not contain any maintenance or service information for defective class engine pistons or piston ringlands."
Two weeks ago we had to take our 2018 Subaru WRX to the mechanic for the third time. Engine related problems every time. Love the car but hate how unreliable it is.
suit seems to be over sti engines and ej25 for wrx eyars 2009-2014; even then ej25 ringlands don't fail once a year but you have an fa20
That's strange, the regular (non-STi) 2015+ WRX utilises the very reliable FA20DiT engine, not the EJ25, which is notorious for ring land failure.
I'm fairly sure the WRX for those years has a 2.0L FA series engine, not a 2.5L EJ series engine.
FA came in 2015 for wrx, ej is still in current stis. For 2022 it is rumored it'll be fa24 for both (obviously STi will be more powerful).
The FA24 is built in North America, and is sold into that market exclusively.
I just took my well maintained stock 2015 WRX to the dealership for a wheel Bearing replacement. They text me the engine went out (rod bearing) while testing it which will cost me almost $17k. I had all mile maintenance done, oil changes on time, and I never tried pushing the WRX. As much as I loved the WRX, you can expect the engine to go out around 90k miles (assuming the dealership was not responsible of course). Seems like this is a common WRX theme.
That's no good at all. I have a well maintained, regularly serviced MY17 WRX with 55,000 k's, and I find this quite shocking. I was under the impression that FA20 reliability was vastly improved over the EJ25, perhaps I was wrong... Perhaps you just got a bad motor? Is there evidence of the FA20 dying at 90,000 ks being a common occurrence? Cheers
Hi Daniel, I never had any issues with the WRX and never would have imagined catastrophic engine issues. Most of the car miles were easy interstate and I was the only owner. Talked to some local mechanics and the response was “happens more then you would think”. That being said I don’t know if other drivers had mods or how they drove their car. I am curious to see how common this is as more WRXs are reaching the 100k miles. I hope you have a different experience.
