Subaru Hit With 3rd WRX/STI Engine Failure Lawsuit

Subaru faces a third lawsuit over alleged WRX and WRX STI 2.5-liter engine failure. See why the 2.5-L boxer is under attack again.

Subaru of America is facing another lawsuit over alleged engine defects in the 2009-2014 WRX and WRX STI performance models. Both models are powered by a 2.5-liter turbo boxer engine in which the newest lawsuit contends a flaw in the pistons causes premature engine failure.

This is the third lawsuit against Subaru’s WRX and WRX STI performance cars in the last six months. In October of last year, Torque News reported Subaru of America (SOA) had a lawsuit filed against them claiming "an insufficient supply" of oil to connecting rod bearings caused engine failure from metal shavings in the oil in 2013-2014 WRX and WRX STI models. In December, a second lawsuit was filed 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.

The Courier Post reports a third lawsuit has been filed again Subaru of America. The article says, 2009-2014 WRX and WRX STI performance models have “improperly designed and manufactured pistons.” The lawsuit contends cracks in the piston ring lands, (separations between the piston rings) can cause complete engine failure and subject owners to costly repairs.

This third lawsuit was filed last week on March 18, by Christopher Thompson, a Subaru WRX STI owner from California, who is seeking more than $5 million in damages. Thompson’s attorney, Gary Graifman with the law firm Kantrowitz, Goldhamer & Graifman, P.C. of Chestnut Ridge, New York, declined to comment in the Courier Post story.

The third lawsuit says Subaru Corporation used modified 2.5-liter engines from Forester XT and some Outback turbo models and pumped up performance to provide nearly twice as much horsepower for the WRX and WRX STI models. The lawsuit contends the changes in the high-performance cars were made in a way that was cheaper for Subaru but “did not include necessary internal engine modifications to prevent damage to the piston ring lands and left the piston “more brittle” leading to engine failure. The suit also alleges Federal clean air standards led the Japanese automaker to make adjustments “that further strained the already overstressed internal engine components.”

All three of the lawsuits assert Subaru of America and Japanese parent company, Subaru Corp., concealed the alleged problems from customers. With thousands of 2009-2014 Subaru WRX and WRX STI sedan and hatch models on the road, there’s the potential to cost Subaru millions. Michael McHale, Director of Corporate Communication for Subaru, told the Courier Post, "We deny the claims and point to the long history of WRX sales" he said Wednesday. Stay tuned.

I commented earlier but as I read comments about ticking sounds and things I grow more curious. My car is now at 122.5k miles (11.5k more then @the time of last posting) and I have had a slight tick sound that doesn’t grow louder as my rpms go up but the slight tick sound increases in speed (durr) but I thought it was my injectors rocking or something since every time I bring my car into a Subaru dealer and have ANY work done they comment on how clean my engine is and sounds especially for a MY09 premium wrx that has seen long interstate drives (1500 miles @ 80mph+ and 36 hours later the same trip back...) and I have been made aware that, although at idle I only see condensation, once I go over about 2500rpm’s it turns to a slightly darker smoke and when I try to get on it my car sputters through higher rpm’s and I had a dealership start checking out what the problem may be but was paying out of pocket and found that my car is misfiring on cylinder 1 (they put a machine on it and drove for like 20 minutes to check for misfires) and it had a stored code for cylinder 3 (I think) which are both on the same “bank” (side of engine) and then there’s the fact that if I step lightly on the gas at a stop there’s a point at around 2k rpm’s where my car will start to shimmy and shake from the misfired and if I hold it there for like 3-5 seconds (only done this once and it scared me so bad I haven’t since) my check engine light came on flashing which means DO NOT DRIVE which I learned on google before I drove with it like that but when I brought it to my Subaru dealer they said they didn’t notice anything but that’s not surprising since when I bought my new clutch and flywheel and paid $2200 it made noise every time I let out my clutch pedal (not in gear) and it is a squeal that lasts 2-5 seconds unless I push in my clutch and release it again, it only does it when it’s under about 40 degrees F and if it’s 20 or colder when I let it out after starting it (again, in neutral) the car will lunch forward between 2 inches and a foot and if I hold the break it feels like when you let out the clutch on a car to fast and it bucks! Subaru was made aware, I brought it to the same Subaru dealership (not the dealership that replaced the clutch, this is the one who checks it out all the time and replaced my timing belt and idler pullies) they said they couldn’t hear anything... even when I took their foreman and a tech out and I could hear it and kept trying to point it out and then they said it’s because “the clutch was installed so well that it’s really tight and that’s why it lurches forward and that’s why it makes a squeal when it’s cold and I release the clutch when not in gear!!! I know this is a long message but my extended warranty is only good for 2k more miles or another 5 months and I’m scared that either my engine is starting to fail or my turbo is or something and my only local Subaru dealer is all very crappy and the place that did my clutch and transmission case is 185 miles away... I’d love to hear any suggestions for anyone who chooses to read my short book here... lol! Thanks all in advance.

P.s. I’ve owned probably 12 Subaru’s from model year 1990-2005 and EVERY SINGLE ONE had over 200k including my first 2.2litre impreza outback sport with 265k miles and the only thing wrong was the rocker panels were completely rotted out and my front passenger wheel bearing let go on me and I drove it almost 10 miles with my tire flapping at roughly 10 mph and I had a 2004 impreza I went into a 3 foot ditch with after falling asleep, woke up and straddled the ditch u til I hit a paved driveway at the end... while impreza went airborn and it pushed the passenger front tire back about 6 inches, suspension and all so I drove home at 25-35 mph with the tire turned towards the right as if I was going around a slight right hand turn... I drove about 10 miles like that that time too. It’s hatd for those of us who had such faith in subaru and have been driving them for over 20 years and then to hear all the horror stories makes me co sided buying a Ford Focus RS or V8 instead of a new STi limited as I had originally planned. Old winter beater Subaru’s are fine but give serious consideration to buying a newer one. Just like so many people put exhausts and cold air intakes and down pipes on their cars and don’t know about boost creep and blow their engines because of too much psi or they do things and don’t get their cars tuned... not saying that’s why anyone here had issues but I know people who have had issues because of it. Thanks all for reading.

Anyone who is reading this because you had similar engine failure, and you're not covered by warranty, YOU NEED TO GET ANGRY ABOUT IT RIGHT NOW. I only suggest this because, if possible, it is very likely to get you some form of assistance.

This whole situation hit me directly it the chest. I lost my job due to complications from depression a month earlier. I cried hard over this. Back in 2009, 4 years before I could afford a WRX or STi, I used to mod GTA just so I could drive one around. Every time I heard one it would hurt my soul because I had wanted one for so long. I even have a photo of mine before it was unloaded off the truck transporter from the sea port.

Back to the point, I had just lost my job and I gave Subaru of America a call on the phone. The woman who answered asked some questions. I told them I had not towed my white 2013 hatch to a dealer yet because I already knew exactly what the problem was when I heard the knock. When she asked if had made any modifications to the car I told her that I had ONLY put a different cat-back exhaust because I specifically did NOT want to complicate my warranty eligibility, although my warranty ended at 60k and I was at like 103k. I did oil and air filter changes myself with genuine Subaru parts. I spent a lot of money on Platinum Full-synthetic.

She told me that they would need receipts for all of my oil changes or receipts for purchases of oil and filters. I explained that I no longer had information going back to 2012. I told them I was aware of the lawsuit settlements. She then stated they wouldn't cover the repair because I had modified the exhaust. (I love Nameless Performance) I ended up starting to cry and told her to F*ck Off before hanging up the phone.

The next day, I called back and got someone else. I demanded to speak to a supervisor immediately. They took my information and told me I would be contacted by someone. I took notes about what I wanted to say.

A couple days later, I got a call from someone at Subaru of America. I told him that I was pissed, I had babied my car, and I was aware of the lawsuit settlements for this exact problem. I explained that my recent unemployment now left me with endless free time to STAND OUTSIDE YOUR DEALERSHIP WITH A SIGN EXPLAINING WHY SUBARU IS NOW UNRELIABLE. THERE IS NO "LOVE" FROM SOA. I told him I would sell my car for what I could, sell my wife's Forester XT, and tell everyone I meet to never buy a Subaru.

I was very upset and he actually tried to calm me down a bit. He explained that Subaru wanted to help and said he understood that I was a passionate enthusiast. He told me that I needed to get my car into a dealership to be properly diagnosed. I explained that I could not afford this right now. He told me to contact him once I was able to do this. About a week later, I got it towed.

During that week and while the dealer was tearing down the engine, I contacted him a couple more times explaining my frustration with the situation and how it was impacting my mood on a daily basis. He reassured me that they were taking me serious because he was the head of customer relations for SOA. I did not previously notice this and was able to confirm it via google searches.

He contacted me once the car was torn down and the dealer was able to make a diagnosis. He told me it was caused by bearing failure and that SOA would completely cover the cost of a new short block, plus turbo and labor. It took a while for me to actually get happy about this. I was convinced that I would never be able to trust this car again.

I ended up putting about $1500 on a credit card for extra maintenance I approved, while they had everything apart. Once it was up and running and I was able to drive it away from the dealer, I felt a lot better. The dealer provided a 1,000 mile warranty on the new short block. I'm back to rumbling around town again, although with less confidence.

I'm not sure how I feel about this "Confidence in Motion" motto...

I think you may find the Subaru oil pump pickup barely adequate. That can be replaced I read 'somewhere'. Horizontal motors may. I suggest, have less adequate placement of splash lubrication into the bore than vertical engines.

I bought a 2014 WRX brand new back in 2014 and owned for just a short period of time before I made Subaru buy the car back from me. First, the number 3 cylinder wasn’t getting any oil and had a horrible knocking noise. I luckily was able to make it back to the shop before the motor blew. They fixed it a d then sensors kept going and it was never the same sensor twice. On top of that, it was like clockwork; just about every 3 weeks a sensor would go bad and I’d be without my car for 2-3 days. Out of a total of 6 months I had the car in my name, I actually drove it for about 4 months. I was without my car for close to a total of 2 months. I had to make a nasty phone call to Subaru Corp to get someone to buy it back.

2009 Subaru Impreza WRX premium and the motor is going bad. Mechanic said due to bad ringlands and head gaskets is going bad also. Not even a 100,000 miles yet

Is there another class action suit - I was involved with the first and now almost 3 years to the date same failure. Anyone have any info on who to contact?
I had posted earlier this week, but my comment does not come up.
Thanks for any help - Subaru has to take accountability not just with silly gifts!

My 2011 sti hatch just spun a rod bearing at 150k/km and I can't at all afford to fix this and no one's gonna buy a broke ass car around here.
