Engine And Engine Cooling Problems of Subaru Legacy - part 1

Sometimes when starting from a stop or slowing down to make a turn the engine revs up like I was pushing the gas pedal. When this happens ( 4 times in the last 6 months) luckily I was covering the break to slow down or going very slow from a stop. Each time I was turning left or right. I was able to push the shifter into neural. After applying the breaks the engine slows down.

One hour into traveling on the highway smoke began to come from under the hood so we pulled off to the side of the road. Upon opening the hood, after the smoke cleared, a fire was observed. At that point the passengers exited the vehicle and called 911. There was no warning lights or sounds indicating any problems prior to this. The car burned very quickly and the firefighters extinguished the fire but not before the entire car was burned to ashes. The car is wrapped and in the possession of the insurance company pending investigation.

Subaru has released a service bulletin regarding concerns with the thermo control valve in specific vehicles. Unfortunately, individuals with vehicles bearing a rebuilt title, including myself, are required to cover expenses exceeding $2,000 out of their own pockets. Despite evidence indicating that the issue with the engine area is unrelated to the vehicle's rebuilt title, Subaru has chosen not to initiate a recall. This unequal treatment of titled vehicle owners is unjust, especially considering that these vehicles have passed all necessary local inspections and regulations to be deemed roadworthy. All vehicles falling within the designated mileage and age parameters should qualify for assistance. It is my belief that a recall must be issued, as this is a mechanical flaw present since the vehicle's initial manufacturing. In the accompanying service bulletin, Subaru acknowledges fault by stating that they have developed a more reliable and durable component. A p26a3 check engine light code.

The contact owns a 2025 Subaru Legacy. The contact stated that after starting the vehicle there was white smoke coming from the exhaust pipes. Additionally, while driving at an undisclosed speed, the vehicle experienced a misfire with a rattling sound coming from behind the dashboard. The vehicle was taken to the local dealer who was unable to determine the cause of the failure. The failure persisted and the vehicle was taken back to the local dealer and a field tech engineer was sent to inspect the vehicle. The contact was informed that the scavenger pump turbo and catalytic converter were replaced; however, after retrieving the vehicle the failure reoccurred. The vehicle was not yet repaired. The failure mileage was 1,500.

For context, we are the original owners of the 2018 Subaru Legacy car (leased in 2018, and then purchased outright in 2022). At the time of the incident, the car was in pristine condition. We had the oil changed in accordance with the maintenance agreement during the lease, and then every 6,000 miles or whenever the dealership called us to bring in the car. The car had 39,000 miles on it at the time of the incident and had an oil change as recently as 2. 5 months prior. While stopped in traffic, the car began making a sputtering noise and all the lights on the dashboard turned on at the same time. When pushing on the gas the car began rolling down the hill towards the car behind me. I put the car into park and then turned it off, and then waved traffic to pass me. After reinserting the key into the ignition, the car began to make the sputtering noise again, but I was able to move the car very slowly onto the shoulder of the road. The greatest danger is that this occurred in moving traffic. Thankfully, there was no harm done to me or anyone else. I had the car towed to the nearest auto mechanic shop. Initially, the shop informed me it was an issue with the spark plug, but upon further investigation, they told me the problem was with the engine and asked me to bring it to the dealership. The dealership is unsure of the exact issue, but stated that it was engine failure (more details in screenshots below). The technician has stated that we will need to completely rebuild the engine to fully identify and fix the problem.

The contact owns a 2016 Subaru Legacy. The contact stated that while driving at 60 mph, the check engine warning light illuminated. The contact became aware that while the check engine light remained illuminated the horn failed to function as designed. The contact stated that after the check engine warning light issue was resolved the horn returned to normal functionality. The vehicle was not taken to the dealer or an independent mechanic. The manufacturer was notified of the failure but provided no assistance; however, the manufacturer informed the contact that the failure was a known issue and advised the contact to stop driving the vehicle until the check engine warning light issue was resolved. The failure mileage was 184,000.

Catalytic converter plugged at 56,000 miles. Cause the catalytic converter to get red hot and melt O2 sensors. This caused the cel to eliminate and make the safety features turn off. I plugged an obd2 reader in to the car and diagnosed the problem. I had to replace the entire catalytic converter assembly under the as well as all of the O2 sensors.

The engine thermo control valve has been defective and Subaru has known this issue since 2022 and has tried to do some software update but it is defective (https://static. Nhtsa. Gov/odi/tsbs/2022/mc-10222348-0001. Pdf) despite multiple tries. This can overheat an engine, result in the front collision warning system (eyesight) and rear auto-braking not working. Specific to my case, the front and rear collision warning systems are off, auto lane departure avoidance system is off, the engine can overheat and has had reduced performance, and the check engine lights are also on.

Keep burning oil. I’m being told it’s normal and I know for sure it’s not leaking.

I have a 2018 Subaru Legacy 2. 5. The front catalytic converter failed April 2022 with 130k miles. The part was replace by Subaru and the part has failed again. Oct 2023 with 180k miles. Exhaust fumes enter the passenger compartment (which are carbon monoxide). The same part has failed two times in a short period of time. Subaru states this is not a warranty issue . This must become a recall.

Thermo control valve has malfunctioned. It disables all driver assistance, like lane assist, blind spot, rab, collision braking, etc. I have seen on many forums that this is a known issue, across multiple vehicles from Subaru from 2019 to about 2021. The was a TSB put out about a new and improved part to fix this known issue.

A friend was trying to move the car from the street when it suddenly lurched and accelerated and hit a tree, and boulder, and another car. They had not stepped on the accelerator yet. She lost control of the car. It was totaled as per state farm.

The contact owns a 2018 Subaru Legacy. The contact stated while stopped at a traffic light with her foot lightly depressing the brake pedal the vehicle independently accelerated and crashed into the rear bumper of a vehicle stopped in front of her. The contact stated no warning light was illuminated. The contact stated that her front bumper, radiator and part of the frame that supports the bumper had been damaged and needed to be replaced. The radiator had been damaged and leaked out all the coolant. There was only minor damage to a trailer hitch on the rear bumper on the vehicle the contact crashed into. The other vehicle was able to drive away from the scene of the crash and the contact drove her vehicle to a nearby repair shop. The police were not involved. The manufacturer had not been informed of the failure. The failure mileage was approximately 50,000.

At 26,469 miles the harmonic balancer separated into two pieces while driving causing sudden loss of power steering. I contacted Subaru for assistance with this know problem. They refused a free repair. I have been a master ase mechanic for over 25 years at a dealership and know repairs of this type are usually done in house under a goodwill policy, otherwise swept under the rug so there is no recall. I went to the local dealer here and the tech there said he use to do the repair almost everyday. The same thing happened to my housemates at some time and he doesn't remember the details. This is a serious problem and there should be a recall as it could result in death given the circumstances the driver is driving in.

Short block needs to be replaced ($6,500) yes, scenic Subaru has the vehicle awaiting status of repairs (who is paying for service) yes, my safety is at risk as the oil light has come on during the night when I'm alone on a deserted road. Service department knows what the problem is - they are seeing alot fot this problem. Unknown on inspections yes, warning 'low oil' light came on. The oil light kept coming on. All service and maintenance done by Subaru. Now, Subaru service department informed that the short block needs to be replaced. From my research, it seems that this is a common problem with newer Subaru engines because they use a liquid engine sealant at the factory and when oil sits on the seals when the engine is not running, the sealant degrades and begins to leak. They also said there was nothing we could have done to prevent this and reiterated just how common with Subaru's. Replacing the short block on a car with low mileage (<75,000 miles) should be paid for by Subaru as this is a known manufacturing issue. I should not have to pay for this repair. Also, Subaru said trade in value has dropped due to this issue. Please email or call me as soon as possible. Peggy rees 305 marion st mount airy, nc 27030 phone 336. 657. 1812.

When I brought car in for an oil change. Cam carrier leak, was reported to me that there was a cam carrier leak. When I look online there are countless reports of this. Seems like there could be something faulty with the engine. Subaru offered to cover the repair as a 1 time curtesy. But if there is an issue with the design of an engine then this should be looked at further. The rear brushings are also failing don't think this should happen so quickly, maybe faulty brushings. No warning lights.

The contact owns a 2012 Subaru Legacy. The contact stated that while driving at various speeds, the vehicle stalled. The driver had to park and restart the vehicle. The vehicle was slow to accelerate. After adding fuel to the tank, the fuel dissipated. There were no warning lights illuminated. The vehicle was taken to an independent mechanic, who informed him the throttle body and valve needed to be replaced. The vehicle was repaired, but the failure recurred. The contact called the local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 200,000.

When running on a highway and you press down on the accelerator hard to merge onto a highway or go around a vehicle to move out of the way of vehicles quickly coming up behind you, the engine takes over and speeds up on its own. It has occurred three times on a newly purchased used car and it will increase speed up to 100mph. You have to press intermittently on the brakes to pull over to the shoulder and turn off the car for five minutes for the car to reset. If you try to just break, you get a burning smell. I see two class action lawsuits on similar acceleration issues for 2015 to 2017 outback/legacy series.

Check engine light came on at 55,500 miles on exactly the third anniversary of purchase. Local mechanic determined the code related to thermo control valve failure. Apparently an ongoing issue with many Subarus since replacing the thermostat with this in their cars. Lost all eyesight features, including cruise control and high beams, as well as cabin heat in the midst of winter in the northeast. A simple google search reveals many instances of this subpar part falling on Subaru cars. $1,066 later, I feel a recall or coverage under powertrain warranty is warranted.

In August & September 2022 , 4 times I was stopping at stop signs & red lights and my car shuttered & stalled. No warning lights showed on the dashboard. I contacted my mechanic & he said he was aware of this issue on certain Subarus, possibly a torque converter defect but thought there was an extended warranty & I should look into it. My car was purchased 7/30/12 & had 103,000 miles on it when this issue started in August. I wrote to Subaru of America explaining the problem. They told me that my car was out of the “warranty” since it expired at 100,000 miles or on 7/31/22. They said I’d need to take my car to a dealer & have them diagnose the car, & if it was this issue then it would be reviewed to see if they would offer any “good will assistance”. After reading many blogs I’m noticing many Subaru owners complaining of similar dangerous stalls. Why hasn’t Subaru been forced to recall all these vehicles? this is a dangerous situation. I also read an article in forbes magazine from 2017 by chris jensen that Subaru was allowed to offer extended warranty on this faulty transmission part instead of a recall being issued. I. Don’t understand how you can overlook this safety issue. I would like to know what recourse I have since this started happening just outside my warranty limits. Subarus comment “ it would be reviewed to possibly offer some good will assistance” is just not good enough. I would appreciate a response and some assistance in this dangerous situation. I have a date set in October to have my mechanic check it thank you.

Please see odi#11486236 & request # 562681 “ part 1” I wrote complaining about a 2012 Subaru Legacy torque converter issue. It was “ out of warranty 7/31/22 or 100k miles. At the time it started stalling it was at 103k miles in August 2022! I did not feel comfortable driving it. On 10/19/22 my mechanic drove my car & it shuddered & stalled at intersections for him also. I did not feel comfortable driving it 25 miles to a Subaru dealer to have them check it, diagnose it & repair it. My mechanic replaced the torque converter as well as the appropriate fluids. It cost about $1500 for parts & labor. Since this is a faulty part installed prior to purchase I feel Subaru needs to recall all these vehicles affected. I emailed you multiple emails online multiple complaints about this faulty part which causes a dangerous situation stalling at lights & intersections requiring one to stop & start. I was almost broadsided a few times. Subaru should do the right thing and recall all vehicles involved & your agency should do the right thing & demand it for the safety of the public.

Head gasket keeps getting blown not only that overheats after fixtures with the radiator pressure not flowing normal car been fixed more 4 times for radiator issue and now at the shop for the second time for head gasket blown and radiator issue what can I do to this point car has turned off on me on the high way due to overheating and I had to react fast in order to avoid accident.

Car stalls when coming to a stop. This is a known problem with an active TSB but Subaru will not support repairs. This is dangerous when engine quits unexpectedly.

I’m having an issue with my vehicle stalling when I brake and when I come to a stop slowly or on an incline. I haven’t had it tested at a dealership but I have read about the issue among other Subaru owners stating it is possible the torque converter in the cvt and that Subaru isn’t recalling it. I see this as a major safety concern for myself and others on the road due to its stalling out at a stop or on an incline.

Three identical instances. 1. Was driving down road came to stop light pushed brakes and car stalled out. 2. Was approaching roundabout pushed brakes to wait for traffic and car stalled out. 3. Was on incline at stop pressing brakes, went to push gas and car stalled out. In each instance the car dies completely. You have to take key out, put back in and turn on the vehicle again.

Subaru refuses to do a recall for their cvt transmission issue even though this is a know issue with the 2010-2012 Legacy. The car stalls when coming to a stop. Subaru never informed their owners of an issue and now refuse to pay for any repairs, if this was to become a recall then they would be required to pay for the repairs, and then there would be less unsafe vehicles on the road.

1. When coming to a stop the vehicle will shudder and stall. Vehicle drives fine until slowing down to and then will sometimes shudder and stall. 2. The car stalling when slowing down others drivers can hit you as they do not expect you to come to a complete stop. 3. I am taking the car to the dealer tomorrow. 4. I have notified the dealer of the issue and I have found two bulletins from the manufacture regarding this issue, which I found from other people who have complained of the same exact problem with their make of vehicle 5. No warning lights came on, I would slow down for a stop sign and before even stopping the car shudders and stalls, I have to put the car in park to start the and the car so far has started.

1. Car stalls when slowing down 2. Safety issue dealer has listed as torque issue and as safety issue 3. Dealer has vehicle now and report say torque issue with cvt 4. By delaer 5. No lights, car stalls when slowing down.

I just brought this car a few months ago and I have been having alot of problem with it from engine oil low when it not to tpms light coming on and going off to now eletric parking brake locked up now I cant move my car and I work seven days a week and always maintain my cars was getting checked its really weird.

When im on freeways and alot of traffic jams im afraid because I have to stop alot and it turns off I have to always check behind so no one hits me. So please help on makeing this a recal, I see alot of people are having the same problems not just me. This can cause a bad accident so please do t wait for this to happen.

Vehicle had significant amount of oil pooled in the battery case holder back approximately Jan 2022 or earlier. Contacted Subaru of las vegas and they offered to clean the vehicle believing it was a careless oil change. Next oil change Subaru said I had a minor oil leak. Took it to an outside vendor to have them look at it and they said I didn't have an oil leak. Every oil change after that Subaru continued to say I had a leak. But, my oil levels never changed enough to show low oil. Took it to the same vendor again and again they said no oil leak. Took it to another vendor and they changed the gasket cover and leak, but mentioned there was a leak with the cam carrier that needed to be revealed. They recommended taking it to their neighbor vendor that specializes in Subaru and they looked at it and confirmed, but mentioned to contact Subaru and that it should be a covered repair as it is a known issue with Subaru and that they were currently working on one with the same issue. While recently driving it, I noticed what smelled like burning oil. When I looked online I can see numerous years and models of owners reporting the same issue with their Subaru. Contacted my dealer and they said it wasn't covered. Contacted Subaru of America and they are currently investigating it. If your camshaft seal is leaking oil, you need to get it replaced right away. The leak can lead to a fire, and your engine could seize up. It can also damage your timing belt which can cause bent valves, cylinder head damage or camshaft damage. Prior to this, I actually have already repaired the timing belt. I want to ensure that no injury or damage comes to another Subaru vehicle owner having the same issue. I have also just had to repair both axles and my Subaru is a 2016 with 90,000 miles on it.

Car battery has discharged on three occasions within the passed 6 months. There is no warning that the battery is failing, turn car off and go to turn on next day and it won’t start. The battery is one yr old and mechanic gave it passing mark when he checked it. When I researched internet to gather more info I found the class action lawsuit describing my problem on other Subarus and felt it should be documented.

10/4/21 engine suddenly surges while waiting in line at bank -- thunderous roar, heavy shaking. Assumed it was transmission problem. I put it in park and removed the key to stop it. I got out of car because I was scared. Got back in after a few minutes and started it up again. It shook and roared again. Turned it off and got back out. After about half an hour I tried again, and it seemed to run normally. Afraid to drive it home, I pulled into bank parking lot and called my husband for advice. It is a risk because car could accelerate unexpectedly and hit someone not yet seen by dealer but I plan to take it in for repair no warning indicators noticed prior to this for some weeks, car shuddered frequently when braking.
