Other Fuel System Problems of Subaru Legacy - part 1

Subaru puts on plastic fuel tanks, and overtime the connections that connected to the car that are metal will rub a hole into the fuel tank and caused leaking. If you park this in a garage a puddle will form any spark, such as a outlet will ignite the garage and blow up the house.

2015 Subaru Legacy 2. 5 engine. Fuel gauge is inaccurate. My daughter was on the highway when it ran out of fuel. Had car towed to a independent shop. They said that the fuel gauges is a problem for Subaru 's and that they had seen it before on other Subaru's.

The thermo control valve is faulty and my friends is too. There is a class action lawsuit concerning this part. I replacement part was designed in 2021 and Subaru is aware of this issue, but refuses to do a recall. So far 2019, 2020 and 2021 models are affected.

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.

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.

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.

Fuel pump failed. Available for inspection upon request. Vehicle shut down near a busy intersection. There were no warnings, just failed while leaving a restaurant.

I had a episode of sudden unintended acceleration while I was driving in the highway. If I would let the brake pedal go, my car would probably escalate its speed to maximum until it crashes. The rpm was almost 5 even though I was applying the brake. I could not make it stop by applying the brakes at all . I only could make it finally stop when I changed the gears to neutral and them to park and finally turn the engine off. I was lucky I was in the highway and when I got in the first light it was green, other wise an accident would've happened.

A smell of gas was present in the passenger area. I took it to my mechanic. He said the damper fuel assembly (part # 42086ae040) was leaking. It is a high pressure gas hose. Subaru no longer makes the part, making the car valueless. We tried junkyards, etc, but that part seems to be leaking on all. It is dangerous. I can drive it, perhaps, but the gas smell is in the body of the car. Subaru said it's "unfortunate" that the car that was worth $6-7,000 last week is worth nothing. Unless I want to drive it unsafely.

The catalytic converter has been replaced twice and is now needing a third replacement. The car emits gas fumes, unsafe emissions, and the fuel causes the mechanism to be extremely hot and unsafe. Over time, the car has had reduced gas flow and will stop running. The dealer has confirmed the three converters installed have been defective. The manufacturer, Subaru, was contacted to inspect the car but refused. Precious years have recalls of the fuel mechanisms. The check engine light stays on when unsafe emissions are detected.

Acceleration is uneven/hesitant. I think it’s the fuel pump. 56,000 miles on vehicle.

Vehicle stutters and frequently stalls when coming to a stop. The more aggressive the braking, the likeliness of stalling becomes higher. The vehicle needs to be put into neutral to be restarted. This also occurs more frequently in colder temperatures. The older the vehicle the more obvious the issue becomes. Currently 99500 on a 2010 Legacy. The dealership has confirmed that the converter needs to be replaced, but Subaru USA is unwilling to offer support due to the vehicle being outside the �extended warranty�. The information originally disclosed by Subaru did not say that the vehicle may stall. This has now become a major safety concern which could leave individuals severely injured or dead if this were to occur at an unfortunate moment. Dealership estimated the repairs at about $3,028 plus tax.

The electrical in my car sometimes works and sometimes not while driving the lights for notification of brake or ans go off and on. My headlights will occasionally blink too.

Extreme gas smell in cold weather until car heats up when running heat/defrost. Known issue in other models that warranted a recall.

Acceleration hesitates or stutters when slowly accelerating, like from a stop in a neighborhood. 2018 Legacy 3. 6r has done this since purchased in April 2019.

Always, when the circulation fresh air button is pressed to allow outside air to enter the cabin, there is the noxious odor of gasoline. I replaced the engine because of a timing belt related problem at 160,000 miles and the problem of gas odor stopped for a few months but it is back, bad as ever. When did this happen? years and years.

Changed out the timing belt as part of recommend service by Subaru only to learn that the head gaskets were leaking and it's a known problem with all Subarus built before 2013. Subaru is aware of the problem, and has created a conditioner that is added to the cooling system as a "band aid. ".

I was driving on highway and engine failed light came on, along with low fuel sign. Engine shut off. Luckily I was able to safely pull over. The dealer determined that the low fuel sensor failed thus shutoff the engine. Shutting engine off on a highway is dangerous and life threatening event. Need a different strategy to warn the driver with a time to safely pull over. It cost me over $1,500 to get the part repalce.

While crossing a busy street I was forced to brake hard and quickly because the car ahead of me suddenly stopped. My Subaru's engine then stalled. I was almost hit from both the rear end and from the side because I couldn't start my car fast enough. The dealership indicates that this is due to a bad torque converter on the cvt transmission. This is a known issue with the 2010 Legacy, but they will not and the NHTSA won't force them to do a recall. However, my car is 16,000 miles outside the extended warranty they established when they found out about the problem. They indicated that I could have resolved this issue by July 2018 at no cost. However, since that date has past I'm out of luck and must pay for it out of pocket. Also, the car did not have any of these problems then, so they wouldn't have done preventative maintenance for it anyway. Therefore, I must now drive around a car that stalls whenever I brake. I am going to get in an accident. I just hope I don't die.

Fuel level not properly indicated Subaru"s letter indicated they did not know when or if there would be a fix to the problem.

This only affect 05-06 Legacy gt owners. The up-pipe for the Subaru Legacy gt in these given years have a catalytic converter in there and after a certain mileage, the debris of the catalytic converter breaking down would shoot back into the turbocharger. That would cause the turbo failure and stall the vehicle unexpectedly. The catalytic converter in the up-pipe does not have any indication of % of wear and most non-car enthusiasts would not know what the issue is caused by except for an expensive turbo replacement and up-pipe replacements. Most of the owners of these issues turn over to catless up-pipe but that would cause the check engine light coming on and overboosting or the engine run rich, further damaging the engine. This can be pretty dangerous if a person is on a road trip and having a long drive as it directly impact the drivability of the vehicle. Subaru has recognize the issue and therefore 07+ turbo models all have a catless up-pipe with the ecu tuned to that specification. I believe it is not fair for 05-06 Legacy gt owners to have to suffer from such a critical issue without some sort of compensation or recall. Thank you for your time.

On the dashboard showed that the remain mileage was 70, but it stopped all the sudden due to no gas. I almost caused an accident because the car stopped on a public street with heavy traffic. After many times trying to start the car, it did not work; it was completely dead. I had to leave the car stranded to go and get gas to the nearest gas station.

When parking in a parking spot at a school going to work, the car accelerated on it's own and went up an embankment and struck a tree causing extensive damage.

Since November of 2017 while driving the car it has intermittently jerked and shook excessively, bucking like a mad horse. Car was brought in to dealer for diagnosis. Dealer was not able to identify the cause. After several visits to dealer where I was assured the problem was fixed the same problem continued. It should be noted that the car, while driving started to shut down and I needed to be towed to the dealer. Dealer claimed the problem was a faulty spark plug. Car was then returned to me. Yet again the problem persisted and had I to crawl like a turtle back to home. Car was towed again to dealer for another diagnosis. Now the dealer believes the problem is a faulty cylinder (whatever that means). I have no trust in the reliability of this vehicle and am concerned about the safety of driving this vehicle with my family. It be should be noted that the car has been serviced exactly to the instructions per the mileage guidance. I have reported this concern to Subaru of America corporate office. Case # 1-38872409282. Their response is unfair. I am now left with a car that is unsafe to drive and I should not be penalized financially.

In addition, the contact observed a leak of fluid located under the front passenger side of the hood. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The contact mentioned that the odor was more stringent when the vehicle was idling. The dial for the air/heat was fractured and could not be turned off. The failure mileage was approximately 175,192.

Car would not accelerate upon entering the highway after pushing on the gas pedal the car wouldn't do anything . I was able to get off to the side and missed being hit from behind from on coming traffic. . . I notice check engine light and flashing cruse control light. . . Second time some weeks later it did the same thing this is very dangerous because you never know when this will happen.

Engine accelerated at a rapid speed on its own power. . Unable to stop the vehicle with the brakes. Vehicle was in motion in the parking lot. .

While driving, the check engine light comes on and there is no power to the gas pedal. The car is unable to accelerate or maintain speed and the driver needs to avoid potential collisions by pulling over on the road or freeway.

The contact owns a 2000 Subaru Legacy. While driving various speeds in below freezing temperature, the contact detected an odor of fuel coming from the vehicle. The vehicle was taken to the dealer, but was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was 156,000.

The contact owns a 2017 Subaru Legacy. While depressing the brake pedal and coming to a complete stop, the engine shut off without warning. The contact was able to restart the vehicle and it operated normally; however, the failure later occurred several times. The dealer performed diagnostic and fuel testing, which produced a code of p1603 and a good fuel reading; however, the contact was advised to use a different fuel station. The manufacturer was made aware of the failure. The failure mileage was approximately 800.

While driving at any speeds, lose acceleration and need to coast and pull over. Just before shutting off engine, rpms jump to 3-4,000 when in park. Need to turn off engine for at least 30 seconds before being able to turn car back on with check engine light on and cruise light flashing, but have acceleration again. After driving for around 100 miles, check engine and cruise light turn off, but randomly incident can happen again. Had a diagnostic check, confirming throttle position sensor when check engine light was on.

My 2015 Subaru Legacy has at different times (at idle in gear, coming up to a red light while moving, pulling into a parking lot or driving at 45 miles an hour) accereated on its own and would not slow down untill I put it in nuetral. I have to drive with my hand on the shifter at all times to put into nuetral. I bought the car new in 2015 and have 13900 miles on it now in July 2016.

Gas cap lid does not open. We took the auto into dealership June 30, 2015 and gave them TSB-09-60-15. Mileage 5987. Temps in the 70's. They greased the gas lid contact. I indicated the TSB indicated something other than that. They took back into shop and ground down the lid release contact. Drove home. Tried to open gas cap lid and it would not open. We are concerned about driving auto any distance by oneself because it now takes two people to put gas into auto. One to pull up lever and one to pry open the lid on the outside. I am seeing numerous problems with several other Subaru models besides the Legacy. Such a simple manufacturing flaw should be able to be fixed. Love the auto but this is really really an annoying simple flaw. One person's comment on a TSB pertaining to this issue said if the lube and grinding does not fix the issue, the entire cap assembly needs to be replaced. I have not discussed this with the dealer yet. This issue happens in all temps. Currently 60 in garage and cap does not open. Mileage 10365.
