What owners said

2019 Subaru WRX Denver, CO

ENGINE

The cam carriers for my vehicle are leaking oil. This is an incredible common, seemingly almost guaranteed, issue with these vehicles from Subaru at the 75-90k mile mark. The carrier are dripping oil, so worse than seeping, but not pouring. This runs the risk of the engine bleeding oil fast and running dry without checking oil levels every week or so and carrying extra emergency oil. This is a huge safety risk and given the proliferation of this issue across subaru vehicles and the CVT it needs to be addressed by SOA. There are no warning lights for this issue and this would not have been caught if I hadn't gone to the dealership for a general car inspection as I suspected something may be wrong. The problem has been reproduced at other shops/dealerships and is a very common almost guaranteed issue with these vehicles.

2017 Subaru WRX Westerlo, NY

ENGINE

Experienced catastrophic engine failure with no known cause. The car had been inspected and had an oil change 3,000 miles prior to the incident. Thankfully, I had already exited the thruway and was on a quiet backroad but if this had happened 15 minutes earlier on the thruway this could have been a much different story.

2019 Subaru WRX Denver, CO

ENGINE

At 77,000 miles, my vehicle suffered a major failure where the #2 connecting rod and piston were destroyed, requiring a short block replacement. This repair was performed by Autonation West Subaru in Golden, Colorado and was covered under the SAS gold plan, certified pre-owned 7yr/100,00mi. warranty purchased with the vehicle. According to the technician's report at that time, the failure was so violent it cracked the engine block and contaminated the entire oiling system with metal shrapnel. A short 18,000 miles after receiving the vehicle back at 95,335 miles the clutch went out, needing to be replaced. Keep in mind that this clutch had recently been replaced at 35,757mi. by this same dealership who at the time charged me $900 even though I had just bought the car in July of 2021 with 22,000mi on it. Now, I am at 128,000 miles—only 50,000 miles after the dealership repair—and the engine has failed again. Fortunately, just as I was pulling up to my friend's house, it stalled with an engine code of p0171 present and several dash lights illuminated. And all I've gotten it to do is crank but not start, since early September. In October I had it towed to Subie Smith in Thornton, Colorado. Who did an inspection and compression test, reporting low compression in 2 of the 4 cylinders. And recommended a full engine replacement, either used or new. I don't have the means to afford an engine replacement now out of warranty.

2020 Subaru WRX at 30,000 miles Thompson, OH

ENGINE

The contact owns a 2020 Subaru WRX. The contact stated that while the transmission was shifted into neutral (N), the instrument panel displayed that the transmission was shifted in reverse (R), and the rearview camera image was displayed. The check engine warning light was illuminated. The contact shifted the transmission to drive (D), but the instrument panel displayed that the transmission was still in reverse (R), and the rearview camera was displayed while driving. The vehicle was taken to the dealer, who informed the contact that there was no recall associated with the VIN. The vehicle was not diagnosed or repaired. The contact related the failure to NHTSA Campaign Number: 22V522000 (Exterior Lighting); however, the VIN was not included in the recall. The manufacturer was not made aware of the failure. The failure mileage was approximately 30,000.

2021 Subaru WRX Fulshear, TX

ENGINE

In October 2024, my vehicle, a 2021 Subaru WRX STI, was purchased from a Toyota dealership (Fort Bend Sterling McCall Toyota). The dealership sold the vehicle with an oil issue and a modified ECM. This issue caused catastrophic engine failure while driving. The vehicle stalled and could not be started. Subaru dealership technicians confirmed the cause as improper service leading to catastrophic oil starvation. The failure put both myself and others at risk, as the engine lost power mid-operation on a busy road. The vehicle was towed to a certified Subaru dealership, where it has been detained since December 2024. Despite being under warranty, repairs have been delayed for over 6 months due to blame disputes between the dealership, the manufacturer, and the extended warranty provider. There were no prior dashboard warnings or messages before failure, only loss of power and engine noise at the time of the incident. The vehicle has been fully inspected and documented by the Subaru service center, and all evidence has been preserved. I have been without a primary vehicle for over 7 months.

2021 Subaru WRX Chino, CA

ENGINE

I am filing this complaint to report a serious safety concern involving my 2021 Subaru WRX, which is currently covered under the manufacturer’s powertrain warranty as well as an extended warranty. Subaru of Ontario, an authorized Subaru dealership, failed to properly diagnose or repair ongoing engine issues during multiple service visits. Despite documented problems, the vehicle was released to me in a condition that was unsafe to operate since their location did not have a loaner, fully aware of the issues at hand, exposing me and my family to serious risk while driving. As a result of this negligence, the engine has now deteriorated to the point of needing a full replacement. Subaru of Ontario is attempting to charge me $3,000 for an engine replacement, despite warranty coverage that should fully apply. The dealership has refused to acknowledge their failure in prior inspections or take accountability for releasing an unsafe vehicle back onto the road. I am reporting this as a vehicle safety hazard and potential warranty fraud, as the dealership’s actions directly led to unsafe operating conditions and are now being used as justification to deny coverage. I urge the NHTSA to investigate both this specific incident and whether this may reflect a larger pattern among Subaru service centers. I am prepared to provide service records, warranty documentation, dealership communications, and supporting evidence upon request.

2024 Subaru WRX Cincinnati, OH

ENGINE

Driving my car as any person would, at the 3519 mile mark on the odometer the engine low oil light came on, it took (1.5Q) of oil to top it off. This is a brand new car no one buys a new car to add oil to it, then to get told by the dealership that it’s normal for up to (2Q) of oil to be added because it’s the only AWD boxer, but yet the 24 crosstreks have boxers and doesn’t burn oil?????

2018 Subaru WRX San Jose, CA

ENGINE

I have been experiencing a strong fuel odor both inside and outside the cabin when starting the engine. After several months of experiencing this issue, I recently had my vehicle fully inspected by an authorized Subaru dealership, and they confirmed a critical fuel leak issue. The dealership discovered that the high-pressure fuel pipe is leaking, as confirmed by a camera inspection of the engine bay. They have deemed the vehicle unsafe to drive and have strongly advised against further use due to the potential fire hazard. It is important to note that my vehicle has never been involved in an accident, and no prior mechanical work has been performed in the affected area, which suggests this may be a manufacturing defect.

2017 Subaru WRX New Haven, CT

ENGINE

The current issues with my recently purchased used vehicle are as follows: Clutch, odometer tampering, steering rack, 2 axle leaks, electrical issues, inspection issues. I tried to see if the dealership that I bought the car from is willing to fix these issues they keep going back and forth with me on these issues even though I just recently purchased the car stating that I have to pay for it. I purchased this car [XXX]. There were several issues with this car prior to purchase that were not disclosed when I purchased it. The dealership that I bought the car from, highline car connection/Yankee Auto sales, insisted we buy an extended warranty. Upon inspection at Dan Perkins Subaru, one of the biggest safety issues with this vehicle is the clutch, I was informed that the clutch cover was missing and there were aftermarket bolts used, I was informed that the clutch is a normal wear and tear item such as an oil change and because of these two issues my warranty will not cover fixing the clutch. As you can see in my documents I just recently purchased this vehicle and had it for 28 days. I also noticed that there was odometer tampering, I reviewed the paperwork the dealership gave me for the carfax report and I went online to retrieve my own carfax report, there are several discrepancies in which I included with my documents. My vehicle has been in the shop since December 6th 2024 it is not safe to drive on the road in the condition it is which is the same condition the car was sold to me in. For the last week I have been going back and forth with the original dealership the insurance company Allstate with the warranty and Dan Perkins Subaru trying to figure out a way to get my car safe on the road and no one is willing to assist me properly. Please review the documents and get back to me at your earliest convenience thank you for your assistance with these issues.

2019 Subaru WRX Warrens, WI

ENGINE

With 61,700 miles on the car the engine lost a rod bearing going around a sharp corner on and off ramp of interstate highway. If failure had caused block to crack or break it would have put oil down on the highway and would of caused loss of control of the car. From research done online it seems sharp corners cause engine catastrophic failure. Car is currently at Subaru dealership. Subaru will not do anything about the issue. Vehicle had fresh oil change 2 days before failure with no noise or warning before failure.

2023 Subaru WRX Ogden, UT

ENGINE

I would just like to complain about the excess Rtv on the engine oil pan that has been demonstrated on numerous videos of people opening up the oil drain pan and finding chunks of Rtv blocking some of the engine oil pickup tube. I have not opened up my oil drain pan due to cost. This has not lead to failure as of yet but it is worrisome. Thank you

2018 Subaru WRX Edmonds, WA

ENGINE

Engine rod knock at 32,000 miles due to bearing failure causing loss of control of vehicle and sudden loss of power and control. Car was logged to be traveling at 35 mph with normal acceleration at time of failure. Carter Subaru confirmed bearing failure, and fits with the pattern confirmed in 2012-2017 WRX STi engine failure class action settlement, as part in 2018 remains unchanged from 2017 according to mechanics. Head mechanic at dealership confirmed that only car modification (intake) would not cause catastrophic loss of oil leading to bearing failure, and thus it is likely due to engine design that leads to poor oil circulation as a known issue in this EJ25 engine type. Engine components have been inspected by Carter Subaru, and have been made available to Subaru of America, along with images, videos, pictures, receipts, logs, records, computer/ECU data, receipts, tool purchases, and other maintenance and service logs for the car (including prior to ownership). Dealership acknowledges that the car maintenance exceeded the manufacturer recommendation, yet engine still failed even with oil changes done at 3,000 mile intervals... While manual states much higher interval to follow. Engine still failed at increased oil change levels. Problem appeared once engine started knocking, which means the engine has already suffered irreversible engine failure and needs to be replaced, according to Subaru. Subaru of America assigned a customer advocate but has been incommunicado for the duration of the investigation and refuses to answer or even acknowledge that a claim has been opened, as they constantly cite erroneous interactions with the vehicle owner.

2021 Subaru WRX Valdosta, GA

ENGINE

Severe engine failure! Was driving steady speed on highway, then I let off the throttle and heard a bad knocking noise on deceleration. The engine oil temp increased to around 230F. I slowed down to limp it to the next exit and it started jerking. I made it to an exit and the engine stalled at the red light. No smoke, oil level good, coolant level good. Had it towed to Subaru dealer, where they said the engine has severe damage and needs a Short Block Engine Assembly. Warranty was denied because it has a cold air intake. Complained to Subaru Corporate because an intake should not cause catastrophic engine failure at only 38,000 miles.
