A New Subaru and Toyota Engine Failure Lawsuit Includes All BRZ, FR-S, 86, and GR86 Boxer Engines

A new class action lawsuit alleges Subaru's Boxer engines in the BRZ, Scion FR-S, Toyota 86, and GR86 are defective in the two automaker's sports cars. Here are the latest details.

Subaru's Boxer engine is under fire. 

Subaru's 2.0-liter and 2.4-liter Boxer engines in the BRZ, Scion FR-S, Toyota 86, and Toyota GR86 are allegedly defective in a new class action lawsuit

The Subaru and Toyota Boxer, engine failure lawsuit, is massive and includes all Subaru and Toyota vehicles equipped with 2.0-liter and 2.4-liter four-cylinder Boxer engines. T

Subaru, Scion, and Toyota sport coupes that are included in the lawsuit. 

  • 2013-2016 Scion FR-S
  • 2013-2023 Subaru BRZ
  • 2017-2023 Toyota 86/GR86

The Subaru and Toyota Boxer, engine failure lawsuit, includes all first and second-generation Subaru BRZ, Scion FR-S, and Toyota 86/GR86 models.  

It's important to note that the Boxer engine is primarily a Subaru design in the Subaru/Toyota BRZ/GR86 joint venture. This joint venture, formed in 2012, aimed to combine Subaru's expertise in boxer engines with Toyota's knowledge in hybrid technology. However, it incorporates some Toyota parts, most notably the D-4S direct injection system, a Toyota technology used on the four-cylinder engine, allowing for more efficient fuel delivery.

CarComplaints says, "Arkansas plaintiff Laura Young filed the Boxer engine failure lawsuit for more than $5 million for her 2019 Toyota GR86, which she purchased used in October 2021."

"In April 2023, the plaintiff was driving her Toyota when it suddenly lost power, and the engine failed when the GR86 had about 64,000 on the odometer. The powertrain warranty coverage is for 60 months or 60,000 miles, whichever occurs first."

The plaintiff did not contact a Toyota dealership, but she says she contacted an independent auto repair shop after her Toyota GR86 sport coupe was towed home.

"Upon a complete professional teardown of the engine, it was determined that the engine failure was due to oil starvation, loss of the oil film, and excessive wear. Ms. Young's vehicle is still disabled, and Defendants have not replaced her defective engine with a non-defective one," according to the Toyota Subaru boxer engine lawsuit.

What is the problem with the sports car's Boxer engines?

The report says the Subaru Boxer engines allegedly suffer from low oil pressure and a loss of oil film, which damages and destroys the boxer engines due to a lack of engine oil.

The lawsuit alleges that drivers and others are in danger when the Boxer engines fail while driving, and in the worst case, the plaintiff claims the Boxer engines can catch fire.

"Defendants admit they had known about the Engine Defect before the first Class Vehicle was sold yet chose to conceal it from purchasers. Defendants have never disclosed the Engine Defect to Plaintiff or the Class members," the Boxer engine failure lawsuit says. 

The report says that the plaintiff, Laura Young, complains that the Toyota and Subaru vehicles have never been recalled to repair the boxer engines, and the automakers need to extend the warranties. Customers also allegedly have yet to be offered replacements or suitable repairs, and the class action further alleges customers haven't been reimbursed.

The lawsuit alleges Subaru and Toyota used room temperature vulcanizing (RTV) silicone instead of traditional gaskets.

The heat from the Boxer engine allegedly hardens the silicone, which causes it to break apart and find its way into the crankcase. Young alleges that Toyota and Subaru "applied RTV excessively and clumsily during manufacturing."

The fractured hardened silicone allegedly gets into oil and coolant passages, damaging and destroying the Boxer engines.

A lawsuit was filed in 2019 for Boxer engine problems. 

I reported in March 2019 that some Subaru BRZ and FR-S 2.0-liter engines were dying after the recall fix had been done at some Toyota dealers. The report said technicians were applying too much sealant, causing some BRZ and FR-S engines to fail.

A class action lawsuit was filed in 2019 by a 2013 Scion FR-S owner who claimed he took his sports coupe to a Toyota dealer for the recall and had repairs done. One week later, his engine developed a "hard knocking," so he returned to the dealer and was told there were metal shavings in the oil, but the dealer refused to fix it.

The Subaru and Toyota Boxer engine failure lawsuit was filed in the U.S. District Court for the District of New Jersey on July 1, 2024. This could have significant implications for Subaru and Toyota, as they are accused of concealing these defects. The lawsuit, if successful, could lead to substantial financial penalties and damage to their reputations. I will bring further updates when they become available.

I bought my brz brand new from Subaru dealer. In less than 20000km. The engine has abnormal noise, then I check with workshop I used for years. The mechanic said my car hear the crankshaft bearing have excessive wear and confirm this statement by oil change. I saw a lot of metal particle in the oil. Then I towed back the car to Subaru dealer for further inspection. They confirmed my engine was gone. Then have a lot of excuses to reject my warranty. Such 1) as my car has been driven over 235km, ( I didn’t)
2) my car rev to 7000rpm, yes I did. That’s the car for. Also under the maximum rpm.
3) they suspect my car has been tune, not I didn’t. I ask them that u know my car drive over 230km and recto 7000rpm, but don’t know my ecu has been tune? It seems non sense to me. They just keep quiet.
After months pass by they said they won’t warranty my car. Due to I modify the car electric. Which I just simply changed a set of Recaro seat. I asked what the heck it related to the engine itself. They said it exceed Subaru’s standard. So they ask me to pay the engine replacement, they will cover the cost of labour. The car now is still with Subaru dealer now

My 2013 model Toyota 86, experienced engine failure at 121 000 kms. Engine tear down reflected Oil pressure drop causing major engine knock. I did complete engine overhaul at my own cost due to car being out of warranty.

I own a 2019 toyota 86 trd se. My engine has 69,xxx miles on it. I experienced the hard knock, and the first estimate I got was for an engine rebuild priced around $13,000.00. I had my friend tow it home and got a quote from the dealer I bought the car from for a complete engine replacement at around $29,000.00. I had included Toyota Customer Service on this in hopes they'd help; they didn't. I have since ordered a new block with forged internals and other design improvements from a company called Integrity Auto Group. I am still saving the money to have that engine installed and have not been able to drive that car for over a year. Im still making payments on that car.

Toyota 86 was recalled and sent to Mahikeng Toyota. It was never the same after. Engine knock and the car caught fire and burnt beyond repair.

Kevin (not verified)    November 12, 2024 - 6:32AM

I have a 2023 BRZ with about 5000 miles. No issues yet but look into oil not returning to the oil pan after High G right-hand turns. This may be part of the problem.
I love this car.

William Bloomfield (not verified)    November 12, 2024 - 6:58AM

I own a 2014 Scion FR-S. I have 130000 miles and am concerned about this, though I hav not had issues yet.

What should I do, or look out for?

Thanks

Hi my name is sam and i own a 2023 subaru brz limited and it has a terrible oil leak the motor is just filled with oil and i have to fill it every week which is very annoying

I’ve owned a Subaru Brz late 2017 and about to have second engine installed from rod failure link to oil starvation. After haven the valve recall done it failed. So I had a rebuilt installed only to have another failure and currently waiting for tear down to see why. I purchased a new short block from Toyota and an after market 14mm oil pump for increased oil delivery.

Jonathan Sanchez (not verified)    November 12, 2024 - 10:19AM

Yes, I had the same issue. Always kept up with my oil changes and usual maintenance, but my engine still managed to blow out. The car has been unusable for the past 2 years.

George Alvarez (not verified)    November 12, 2024 - 10:51AM

I mostly drive my FRS on the weekends and I'm always on it with maintenance. My car has a little over 84K and it started Knocking. Pretty upsetting since I own other old Toyotas with over 240K which still run great

Michael (not verified)    November 12, 2024 - 10:58AM

2019 brz series.gray - I thought the issue was 2nd gen only? I'd be afraid to have my engine touched by recall based on those stories...

William Ramsay (not verified)    November 12, 2024 - 10:58AM

I knew about the recall and would not take it to Toyota as they ruined so many engines. I might have let a Subaru dealer do it but they said NO. FR s is still running fine at 50k.

Teresa D'Sa (not verified)    November 12, 2024 - 10:59AM

I do not know where to write my thought, so I am writing to you. I owned a 2019 Ascent, with 50,000 kms. This July 2024, whilst driving the brakes failed, and I was unable to stop. Meanwhile the car accelerated to a speed of 150 or so, and crossed the median and struck three cars across the street. Air bags and all the stuff. Car a total loss. How did this sudden acceleration happen? Please let me know? Thanks

My 2017 Toyota 86 had an engine failure in 2022 from lack of oil pressure. The mileage was 25074. The cost for the repair was $6227.63

Patrick Bilancione (not verified)    November 12, 2024 - 11:23AM

I had my engine blow due to engine oil starvation around September of 2023, I had a local buisness rebuild it and ran me $13k for the rebuild. Was going to out a whole new engine in but when my mechanic called the dealers they said they stop selling the full rebuild because of how many issues other people are having aswell so I waited 3-4 months for my mechanic to get all the parts in from multiple different sources just to get this subaru engine running again still pissed that subaru nor toyota could help me out.

Hi

My wife bought an get86 in 2013 brand new from the dealership.

She only serviced with Toyota, on time and never missed a service.

One day out driving we experienced loss of power and the engine ceased up. the vehicle got towed to avtoyota dealership. The vehicle had less than 100 000km on the clock.

The vehicle told us they need to strip and quote,

We then had an independent mechanic open up the engine andbhe confirmedbthat the sump handbook system was full of silicone bits, that lead the engine to have oil starvation.

Toyota never wanted to fix the engine and we ended up swooping the motor with a new second hand engine and had the sump removed and cleaned up from all the access silicone.

Toyota really disappointed us.

I have a 2013 Subaru brz I hit 10x,xxx. I was driving to work and one day my engine was knocking really hard. It was like a light switch was flicked one second smooth and nice the next it sounded like 10000 tap dancers.

Bobby (not verified)    November 12, 2024 - 12:24PM

My engine had the same issues and failed at 55,000 miles and was never on a track. I had to get a replacement engine and still have issues. The engine started knocking and then cut power to the engine. I struggled to even get home that was less than a mile away. I had it towed to a local performance shop where they determined the engine was blown. $10,000 later, I am still getting a check engine light that they cannot figure out.

I've got a 2019 BRZ at 64700km and it is on its second engine. Same issue, lost oil pressure due to rtv gasket failing.

TekOnWheels (not verified)    November 12, 2024 - 1:57PM

2013 10 Series on third engine now...
1st engine knocked complete failure, spun bearings under 30K... Replaced by toyota
2nd engine ~80k miles... Out of pocket... Same issue: severe knocking sounds and power loss

Funny that we are still here, religiously monitoring our oils with the same fate...

Joe Muller (not verified)    November 12, 2024 - 2:03PM

2019 Subaru Forester 2.5 litre with 71000 kilometers.
On Oct.15, 2024 I was on the highway when I heard a clucking noise which got loader by the second. I pulled over and stopped the engine and could not restart it again. Got towed to the dealership.
They discovered iron shavings on the dipstick. I have extra warranty till Sept. 2026 but it took them 25 days to decide to replace the engine which will take another 2 to 3 weeks to fix. Not acceptable.

Kaitlyn muller (not verified)    November 12, 2024 - 2:11PM

I have a Toyota 86 2017 model and one day got it serviced and got it back, it started making all this noises and jerking when I was driving like I was losing power to the engine, took it back to Toyota and they keep saying nothing wrong with it, went on for about a year back and forth from a Toyota shop, causing me so much grief and anxiety. Ended up taking it to another shop and they fixed the problem straight away, the spark plus needed changing badly and were all black and falling apart, Toyota was meant to check and replace them in the first service before all this happened.

As an owner and track driver of both generations of these cars I can say this lawsuit is pure BS. There are a bunch of idiots that dont know how to drive manual well or check their dang oil, then cry when they blow up their cars. None of this is the manufacturers problem and hope none of the people get a dime.

Gary Adderton (not verified)    November 12, 2024 - 3:13PM

My first engine failure was at 50000kms toyota replaced the engine with a short motor that lasted one hour .. they rebuilt it and that failed again at 130000kms . Fourth motor I've spent 30000Aud on rebuilding it. I'm Hobart, Australia.

David Kays (not verified)    November 12, 2024 - 3:27PM

I bought a used 2020 BRZ two years ago. I love my BRZ and have not heard hard knocking sounds yet. I currently have 33k on the vehicle. How can I stay informed about this class-action lawsuit?
