Engine recalls
Subaru is recalling 16,715 my 2007-2008 legacy sedans and wagons, my 2008 impreza sedans and wagons, and my 2009 forester vehicles. Some vehicles may have the cylinder head-side oil supply pipe and turbocharger-side pipe improperly assembled.
On certain sport utility and passenger vehicles equipped with 4-cylinder engines, the water pump pulley center hole was improperly machined.
Vehicle description: passenger vehicles, also service parts supplied to subaru dealers are involved (lot numbers f01 j21d2, f01 j30d2, f02 j09d1, f02 j09d2, and f02 j20d1). The purolator oil filter cans used on these vehicles can fracture causing a...
Latest Legacy engine complaints
To start, I had to replace the engine in my 2024 Legacy that I purchased brand new in June 2024. Subaru of America handled the situation incredibly poorly, I was unable to use any warranty and I was out over 6,000 dollars. Second, my passenger airbag light has been on since September 2024. I was told to replace the sensor the whole seat rail would need replaced and would be over 1000 dollars. Apparently not covered under warranty either. Lastly, god forbid you have to drive West when the sun is going down. MULTIPLE...

times my vehicle has popped the "obstacle detected" while I'm traveling 75 down the interstate and spikes the brakes automatically causing a massive hazard. This is my third Subaru, but it will certainly be my last. Customer service was horrible and issues are not resolved properly.
The contact owns a 2019 Subaru Legacy. The contact stated that while the vehicle was parked, there was an abnormal sound coming from the engine compartment, and the vehicle intermittently stalled. The contact stated that seconds later, the vehicle returned to normal operation. No warning lights were illuminated. The failure reoccurred on several occasions. The vehicle was taken back to the residence. The vehicle was not diagnosed or repaired. The contact researched and became aware of an unknown NHTSA Campaign Number; however, the VIN was not under recall. The manufacturer was not notified of the failure. The failure mileage was approximately 15,000.
Vehicle: 2021 Subaru Legacy Base 2.5i Mileage:~65,000 miles My engine suddenly began making loud internal knocking/tapping noises with no warning lights, no overheating, and no prior symptoms. The vehicle immediately became unsafe to operate. I had it towed to a Subaru dealership, where technicians confirmed the noise was coming from inside the engine and recommended a full engine replacement. The failure happened without any warning indicators, misfires, overheating, or oil pressure warnings. All diagnostics...

(including compression and leakdown) were clean, and the vehicle has been properly maintained. Subaru of America acknowledged the internal failure but only offered $1,000 goodwill toward a multi-thousand-dollar engine replacement. This appears to be a premature internal engine failure on the FB25 engine, which may indicate a defect. A sudden internal engine failure at highway speeds could lead to loss of power, stalling, or inability to accelerate, creating a safety hazard for the driver and surrounding traffic. I am filing this complaint because this type of unexpected internal engine failure at relatively low mileage may represent a pattern and should be tracked for potential investigation.
The Cam Carrier has a leak due to Subaru using a cheap sealant. My car only has 80,000 miles and it is leaking. The subaru is know for this leak after researching it online. They say it is a safety issue cause the oil can fall on the exhaust making in a fire issue.
Engine failed 3 cyclinders blew, car would not start, was able to drive car into parking lot (Einstein Bagels)before failure, otherwise could have been reared ended, as was in heavy traffic on westbound Dundee Road, in Palatine IL. Parking lot was near Dundee and Rand Road intersection
I experienced unintended acceleration while operating my vehicle. I was slowly pulling into a parking space at a gym when, without warning, the vehicle suddenly accelerated rapidly forward. I did not intentionally press the accelerator at that time. The unexpected acceleration caused the vehicle to surge ahead and collide with a light post, resulting in significant damage to the front bumper. Fortunately, there were no pedestrians or other vehicles in front of me, so no injuries occurred. This incident created a...

serious safety risk, as the sudden and uncontrolled acceleration could have resulted in harm to myself or others if anyone had been in the vehicle's path. At this time, it is UNKNOWN whether the issue has been reproduced or confirmed by a dealer or service center. It is also UNKNOWN if any warning lights, messages, or prior symptoms were present before the incident. The vehicle is available for inspection upon request.
Unintended acceleration, on 2 occasions. First occasion, car was in DRIVE waiting at a traffic stop and the engine radically increased it's RPM from idle to over 6000 RPM, remaining there. Braking control maintained the automobile's position. Shifting the car into neutral caused RPM to increase further. The car was shut off, restarted, and seemed to function normally. On the second occasion, which occurred later the same day, the car was off and then started, and while still in PARK with my foot on the brake...

immediately jumped to over 6000, remaining there. Once again the car was shut off, restarted, and seemed to work normally. It was taken directly (and slowly) to the manufacturer's service center at my local Subaru dealership. They have not been able to re-create the problem as of this date.
I am reporting a Sudden Unintended Deceleration event in my Subaru. The vehicle grinded to a halt without driver input. The car stopped in the left lane of a major highway. We put on our hazards and called the state police for help. They were unable to get to us in time. We were hit from the rear. The car's failure created a stationary hazard that led to a high-speed rear-end collision by a Jeep and truck which caused the car to do a 360-degree spin.
Less than 500 miles cabin fills with engine fumes - smells like exhaust/crank case vapors - especially at idle and with outdoor air damper open on HVAC. If you open hood the engine bay smells like gas fumes. Upon inspection looks like passenger side exhaust manifold is leaking with splatter marks on exhaust manifold - fire and health hazard. Subaru corporate in past has been poor to deal with and makes statements like our dealers are independent and we have no control over our dealers when trying to get them to take action. Now I'll have to battle this out and likely with BBB claim. I have Asthma and cannot drive this vehicle with this smell.
Incident ~ 5:40 pm, Geneva NY Weather ~ 10 F, not snowing. Background. On or shortly after being started, the vehicle had exhibited prior incidents of extremely rapid engine acceleration not initiated by the operator. Most recently the day before. The incident: I was in the process of very slowly parking the vehicle in a narrow laneway, and positioning the vehicle behind and in line of one other, both parallel to the laneway, in a small area that had been cleared of snow, leaving the laneway open. First, I...

stopped the vehicle opposite of the parked vehicle's driver side door. Second, I reversed and backed up and positioned the vehicle behind that vehicle. This involved firmly stepping on the brake to stop the vehicle once well behind the parked vehicle. Third, while keeping my foot firmly pressed on the brake pedal, I moved the shift from reverse to forward. At that time, the front wheels were still fully turned to the left. Immediately on completing the shift to forward, my vehicle made a very rapid acceleration. My foot had remained firmly on the brake and had not touched the accelerator pedal. Despite my foot being firmly pressed on the brake pedal, my car surged forward, retracing the path that I had followed while backing up. I could hear the noise of the accelerated engine, and feel the fighting of the brake as the car surged uncontrolled for about four feet and then finally stopped. My foot had been fully depressed as hard as possible on the brake the entire time and did not touch the gas pedal at all. The owner of the parked vehicle observed the incident and expressed concern since the surge was dramatic, and stopped with the right corner of the front bumper of my car within a couple of inches of the left corner of the parked vehicle. The driver's car mat was in the correct position and did not interfere in any way with the operation of the vehicle. I did not inadvertently step on the accelerator. No warning lamps or messages. Cause Unknown.
My 2012 Subaru Legacy experiences involuntary engine stalling when coming to a quick stop, such as in stop-and-go traffic or during sudden braking at intersections. When the engine shuts off without warning, power steering and braking assist are lost, creating a serious risk of collision. This is a known issue documented by Subaru of America in Technical Service Bulletin 16-90-13R, applicable to 2010-2012 Legacy and Outback vehicles with CVT transmissions. Subaru attributes the condition to excessive thrust washer...

wear inside the torque converter, which prevents proper release of lock-up clutch pressure. Subaru describes the condition as similar to stopping a manual transmission vehicle without depressing the clutch, which inherently results in engine stalling. Subaru later redesigned the torque converter as a countermeasure beginning in October 2013, indicating prior knowledge of a defect. However, Subaru never issued a recall or notified owners and addressed the issue only through a non-customer-facing service bulletin. I contacted Subaru Customer Advocacy to report this safety concern and request assistance with the repair (quoted over $4,000). Subaru acknowledged my concern but declined responsibility, citing the vehicle being out of warranty and stating that TSBs are not customer facing. Subaru did not confirm whether the vehicle is safe to drive with this condition. This issue represents a safety defect, not a warranty dispute. Vehicles that can stall unexpectedly during normal braking events pose a serious safety risk, and many affected vehicles remain on the road today.
The Legacy (my third one) was about a month old and had about 30 miles on the odometer. I had no warning of any problem with the car. On or about 5:45 PM on Oct 22, 2025 I was driving my Subaru Legacy when the engine stalled. I was in the HOV lane of an interstate highway. Multiple times the starter failed to restart the engine. Traffic was blocked in my lane and diverting around me. It was dusk with a misty rain. My wife and I were felt we were at high risk of being rearended at any moment. After about 5-10...

minutes, during which we called 911, the engine restarted. Seeing no help from the police available, I judged it was best. to get off the highspeed road. I was able to get off the highway and make it home, about 5 miles away. I have not tried to drive the car ever since this terrifying episode.
At the end of a drive of 75 mi, 55-65 MPH on an 8 lane highway the engine stalled. Stopped in HOV lane. Restarting failed several attempts. Called police 911. Dusk, with light rain, slick highway. Poor visibility. Wife and I prayed a lot. Scarier than my year in Vietnam. Restarted after about 10 minutes, and prior to police arriving. Made it home 5 min away. Neither dealer nor Subaru can recreate or define the cause. My family and I fear the thought of driving again in that car. Not knowing the cause means no one can fix it.
Constant battery issues. I've replaced the car battery 3 times and the car seems to be suffering from "parasitic battery drain". It took a long time to diagnose the issue and I've been to the Rye Subaru dealership 2 times already and they are still trying to fix the issue. This is my daughters car and I'm constantly waiting for a phone call to have the car jump started. She works the night shift and I'm worried about her getting stranded at night.
The contact owns a 2021 Subaru Legacy. The contact stated that while driving at various speeds during colder weather, the heater failed to operate as intended. Additionally, the Eyesight system was inoperable. The check engine and other unknown warning lights were displayed. In addition, the contact stated that the engine failed to warm up as intended after being started, and the engine temperature was 107°F, which was below the normal engine temperature of 200°F. The vehicle was taken to a local dealer, where it...

was diagnosed, and determined that the Thermal Control Valve needed to be replaced. The contact related the failure to Technical Service Bulletin: 09-119-24; however, the vehicle was not repaired because the vehicle had a Salvaged Title. The manufacturer was made aware of the failure. The failure mileage was approximately 60,000.
