Subaru Gets Hit With 2nd WRX STI Engine Failure Lawsuit

Subaru gets hit with a second lawsuit targeting the Subaru WRX and WRX STI 2.5L boxer claiming more engine failures.

Subaru is under fire this week as their WRX/STI 2.5L engine is under attack again. They were just hit with another class-action lawsuit, the second time this year, against their WRX and WRX STI performance cars. In October of this year, Torque News reported Subaru of America (SOA) had a lawsuit filed against them claiming an engine defect in 2013-2014 WRX and WRX STI models. Now, The Courier Post reports a second lawsuit was filed this week claiming a crankshaft defect can cause “premature catastrophic engine failure” in 2009-2014 Subaru WRX and WRX STI powered by a 2.5-liter turbo boxer engine.

This second lawsuit was filed on behalf of Missouri resident Michael Augustine, whose 2010 Subaru WRX experienced engine failure in November 2016. The suit contends automotive engines typically should last for at least 120,000 miles but those with the high-performance 2.5L turbocharged engine “often fail at less than 50 percent of their reasonably expected useful life.”

It says Augustine’s WRX engine failed at 73,000 miles, and he claimed the breakdown occurred close to home, but added, “I feel that an issue like this could present an unsafe situation were it to happen on the many long road trips that I take, often in unpopulated or rural areas."

Augustine says it will cost him $6,000 to $8,000 to replace the engine block in his 2010 Subaru WRX. The lawsuit filed in the Camden, New Jersey court is seeking more than $5 million in damages for people who owned or leased the 2009-2014 Subaru WRX and WRX STI models, and calls the alleged defect “a serious safety issue” because the vehicle’s “sudden power loss and/or stalling severely compromises the owner's ability to maintain vehicle control.”

This second lawsuit goes on to say the defective 2.5-liter turbo engines are “high performance versions” of the same engines used in other Subaru models, like the Forester XT, that earned WardsAuto "10 Best Engines" award, and Outback turbo versions, and says Subaru “nearly doubled the horsepower, but failed to make necessary changes to prevent damage to the connecting rod bearings and main crankshaft bearings.”

The class-action lawsuit contends the problem in the WRX/STI 2.5-liter engine was “further exacerbated by inadequate oil lubrication to the bearings and crankshaft” causing “sudden and catastrophic engine self-destruction as overheated internal parts seize” and by “severe driving conditions.” The suit estimates the number of WRX/STI owners could number more than 100,000 people.

The Courier Post reached out to Michael McHale, Director of Corporate Communication for Subaru, who said, “We will investigate this claim, but in general we stand by the engine in question, which has a long history of proven performance.”

It's worse: Nothing is perfect, but a company should step-up when problems arise – Subaru hasn't, and doesn't, hence the lawsuits.
The engines fail. My 2013 WRX not modded and not driven very hard had to have engine rebuilt at 100k. My friends at 65k. Subaru has not stepped up to back their product failure caused by their defects
Give me a break! With hi performance engines, life expectancy is never as good as with lower rated versions. They are driven much harder so even though they have improved internal parts, they can still be broken. Then there is a question of enough maintenance.
Christmas Eve in the middle of the Scottish Highlands we experienced total failure in our 2007 2.5 Sti. 56k miles full service history and to be honest it’s never had a hard day in its life. It’s going to be an expensive Christmas! Subaru UK are as unhelpful as ever so will investigate if any civil actions have been taken against them here.
subaru it's a disgrace regardless TOYOTA owns about 16% of the company! their boxer or flat six engines are useless for a man driving more than 20000 km or 12000 miles a year! uncomparable to my 1990 BMW E34 520i M20B20 straight six engine car! it's at almost 250000 kms ,it's almost 28 years old and runs like new,normal fuel consumption,normal oil consumption 150ml per 1000 kms, normal top speed 205 km/h,normal everything! if it weren't for some rust spots I would say this car is perfect! I would buy it again NEW or get naughty and buy a 535i M30B35 straight six engine! these engines can run for 800000-1000000 milion kms! take that subaru! and think about it!
from my experience i would have them replace the whole freaking thing. Ive have the shortblock on my 13 replaced and it was never the same hatch after that, but dealers when they have to warranty anything especially like (pacific in Hawthorne) they do only whats needed and narrow it down to the least amount of work possible when its not a warranty item they have to take responsibility for they want to replace everything including your shoelaces and charge you premium for everything, thats their game on my 17 i have a full warranty and even tire hazard insurance, the dealer i goto now is trustworthy since i service all my cars with them. i would seriously get a second opinion at a different dealer before they take her apart and then tell you shes all good, mind you down the road if they even for a min missed the timing and or a torque spec-- it will be all on you then they with use the line driver error ( and run it up to S/USA and vote on your cause ) service records are a very important ammunition to keep too..
2013 WRX 52K bearing issue. Under warranty and being taken care of...so far!
My 2012 WRX STi engine spun three bearings at 19,000 miles. The engine was full of oil at the time, and oil was changed every 3,000 miles (superior oil with OEM filter). Pistons & ringlands were fine with no sign of detonation. Engine failed when driving on the highway. I took the off-ramp and the engine died when I came to a stop. I sent the entire long-block to IAG to rebuild correctly.
Mine spun bearing #3 at 29,000 miles. Subaru denied my warranty, everything checked out except for the fact hat I didn’t have oil filter receipts, I have plenty of oil jugs, a aftermarket filter on it and bad ( not horrible) oil that has been changed out but kept because I haven’t disposed of it to prove changes. But nope, they want 9,000$ to replace everything because I don’t have the oil filter receipts, oil looks golden still which would also say something about it being changed. Only aftermarket parts are my spt exhaust which is Subaru factory installed. Time to forge it If Subaru won’t pay
