Problems with 2015 Subaru Forester FUEL/PROPULSION SYSTEM

On average, the 2015 Subaru Forester starts to “feel” problems with the FUEL/PROPULSION SYSTEM and its various aspects after 36 691 miles.

Recently reported FUEL/PROPULSION SYSTEM problems on 2015 Subaru Forester

Same problem as nhtsa id#'s 11299582, 11297748 & 11297188. dealer first did diagnostic check and found nothing wrong. two weeks later same issue. replaced throttle pedal/position sensor ($600) and problem fixed.

Two times, while driving on the highway at about 65 mph, my car lost the ability to accelerate. it was as though the car slipped into neutral. i pushed the accelerator pedal and the rpm's would increase, but the car wouldn't accelerate. it simply slowed down. both times the highway was empty enough that i was able to drift into the shoulder. once i pulled over, i turned off the car and waited a few minutes. when i turned it back on, the car started and acceleration worked as normal. both times i brought it to a local subaru dealership, and after running some tests said they couldn't find any issues, and couldn't help me any further. i've found other people who have experienced very similar problems, but it seems like no one has found a solution.

Tl* the contact owns a 2015 subaru forester. while driving approximately 70-75 mph, the fuel gauge indicator displayed approximately 50 miles to empty and the vehicle stalled without warning. the contact was able to restart the vehicle. the vehicle was taken to harvey subaru (located at 3351 benton rd, bossier city, la 71111, (888) 232-4109) to be diagnosed, but the mechanic was unable to retrieve a fault code or duplicate the failure. the vehicle was not repaired. the failure recurred once. the manufacturer was not contacted. the approximate failure mileage was 50,000.

We were driving in the freeway at 65mph, we had been driving about an hour, on the freeway with some traffic but mostly moving normally. suddenly with no warning nor engine lights, the car reved but didn't respond to the gas pedal. as though it had run out of gas. the low fuel light had gone on already, it turns on around 70 miles to empty, but we still had 50 miles to empty. we pulled over and called roadside assistance to deliver gas since that's all we could figure had happened. after about 30 minutes waiting we decided to try it and just see if it would start and it did! we drove to the next exit and got gas with no further problems, and continued on home after. this was very scary and left my family sitting stranded on the side of the freeway. no engine lights, no codes, nothing obvious to fix. now i'm nervous to drive with my kids in the car in case it happens again.

Twice while driving on the interstate on a 3-4 hour trip going approximately 70 mph using cruise control with approximately 1/12 - 1/6 tank of gas, my engine began to rev and at the same time lost power and speed. the first time i pulled off the road, shut the engine off, waited approximately 10 minutes and was able to restart the engine and finish my trip. it happened the second time with mostly identical circumstances. i pulled off the road, turned off the engine, waited and was unable to start the engine. i had to tow my vehicle to a dealership. they ran diagnostics with nothing turning up. they were however able to start the car when they tried. this was extremely dangerous being in 70 mph traffic and having no speed control. i have the dealership paperwork from the service. now the engine does not seem to have the normal power it usually does when accelerating. *tt*jb

When driving normally (vehicle in motion) and attempting to accelerate, vehicle would not accelerate when accelerator is depressed. happened twice in 24 hours. both times, vehicle did not respond and accelerate when accelerator was depressed, forcing the driver to pull over (vehicle stationary). vehicle then responds normally when resuming driving after pulling over for 3-5 seconds.

Car was traveling at 75mph for 2 hours when going up and small grade incline. engine started revving and car started slowing down very quickly. was in traffic, so had to turn on hazard lights on, and get over to the shoulder. the vehicle felt as if though it was braking. the hill descent control light lit up, but no other lights. car did not stall. i then turned it off, opened the hood and everything looked normal. car was at normal operational temperature and had 1/4 tank if fuel left. car was info for service within 500 miles at subaru. after checking the engine, i started the car again and took off. 30 minutes later, the exact same issue occured.

On 2 separate occasions was driving my 2015 subaru forester (touring edition) at highway speed, 70 mph, the car lost power and started decelerating. luckily both times i was able to get over to the shoulder. the car re-started after awhile. the first time the low fuel light was on but i had over 50 miles left according to fuel sensor. the second time, a month or so later, no low fuel light was on. there were 2 bars left on the fuel gauge. again car totally decelerated and then a few minutes later was able to be driven. subaru dealership claims they have not heard of this problem but someone did call them about it the day before i called. i am scheduling an appointment where they say they will do a diagnostic on it. i am seeing multiple complaints on this exact car on carcomplaints.com this is an extremely dangerous problem and subaru should not be waiting for fatalities to happen before recalling these cars.

Drivers are not seeing my brake lights off and on and pulling me over to telling us to get our lights fixed. i just looked up recalls to find out that we have a recall that no one notified us of for the brake lights. we always have our grand kids and everyone elses in the car on a daily basis which can be a deadly situation... please assist.

Twice in the last four months vehicle has run out of gas while traveling on a level highway despite gas gauge indicating that there was 70 miles still to travel and the gas gauge reading one bar. low fuel warning indicator did not display.

Several times when i slow to turn or slow in traffic then try to accelerate, the car doesn't respond. when i depress the accelerator again, it bucks and surges forward in a jerking motion. its dangerous because someone following behind me in a turn could run into me or in traffic , i could suddenly surge into someone else's car. when i took it to the dealer, the only report i got when i picked it up was that they had re-programmed the computer and test drove it. that was 2 months ago and now i am having the same problem again. every incident took place on city streets. i am alarmed about the other reports i am seeing on this and similar loss of control issues.

When driving at highway speeds, the engine will shut down. this has created very dangerous situations when having to cross heavily trafficked lanes without power to enter shoulder. issue has happened 4 times in the past 2 months. unknown cause as no codes are thrown. video showing issue that i am having can be found at https://www.youtube.com/watch?v=omnp_vkes-k .

My 2015 forester stalled while driving in the middle lane on the nj parkway (going about 65-70mph.) there were no warning lights or any indications that this would happen. i had about 3/4 of a tank of gas left. when the car stalled, it felt like it downshifted and then completely stopped - almost as if we ran out of gas (but we didn't). the electric (lights, radio, heat) was on the whole time. we were stalled for about 15-20 minutes until the cops came. we put the car in neutral and they bumped us to the shoulder. while waiting for a tow truck, we tried to start the car again and it worked (about 30 minutes after the initial stall.) we then drove to the nearby gas station and filled up the car; it took 12 gallons of gas and i have the receipt. the subaru service center cannot find the issue. they said the computer isn't even showing a stall code. this could have been a fatal accident and i want to know exactly what is wrong and know it is fixed before i drive it again. it looks like other owners have had the similar issues.

On 6/7/18 after six hours behind the wheel, while traveling 78mph on cruise control my vehicle suddenly lost all systems, as if it had run out of gas, on interstate 85 in heavy traffic. miraculously getting onto the right shoulder from center lane i sat for 10-20 minutes in shock. thinking i had run out of gas even though no low fuel indicators had shown up i turned the key to see if the instrument panel would turn on. it did, a quarter tank of gas showed on gauge. i turned the ignition key and the engine started. i saw a sign for exit in 2 miles, put on hazards, went 50 mph to exit, straight to gas station. 9 gallons went in proving the gauge to be correct. i stopped for the night and googled what had happened and found many hits indicating a possible fuel system problem. i was still 5 hours from home so called nearest subaru repair shop, they couldn't fit me in for a week. took back roads home, never going over 50 mph. called subaru dealership where i bought my car and they had a two week wait for service. called subaru of america who intervened and local dealer got me in that day. 6/11/18. that dealership could not find anything on the computer and said it had been wiped clean by someone. regardless, i asked if they would look at fuel system but they would not, instead offering to purchase the vehicle for fair market price and sell it on their used car lot to a new unsuspecting customer. took vehicle to another subaru dealer who did pull the fuel system and found fuel transfer pump faulty. this caused my car to think it was out of gas as i traveled. i asked subaru of na if they had seen this problem and they replied "there are no recalls for your vehicle", i know from my google search this is not an isolated event for my vehicle. in fact when i picked up my car the mechanic said he had another subaru come in the next day with same problem.

When you step on the gas to pass another auto, occasionally the auto surges forward at a high rate of speed, not 5-10 miles an hour but more like 25-30. taking your foot off the gas does nothing as the car continues to get faster and faster. applying the brake pressed all the way down barely slows the car. when you let up on the brake it surges forward again at the high rate of speed. i thought maybe it was the 19 degree weather as it did it 3 times on the way to work one day this week. last night it was 41 degrees when i drove home and it did it every time. i almost rear ended someone as i couldn't get it to slow down to a normal speed even with the brake applied. i am afraid to drive the car. happened on a major freeway and on rural county roads when going straight

The car lost all power in the middle of interstate 95 heading south approx 17 miles north of the ga fl state line. the fuel indicator showed 30 miles until i had to refuel. this was on 12/3/2017. i was at speed(75 mph) and managed to go through traffic and go to shoulder. there was no power and the engine had quit. i waited a couple of minutes and the car restarted. i drove to the second exit and refueled. a few days later on 12/06/2017 on the way back to atlanta on i-95 south of savannah and the fuel gage reading 30 miles until i had to refuel, the very same thing happened. except, this time it would not restart. i called aaa and continued to try to restart. after 45 minutes, the car restarted. i drove approx 10 miles and refueled. i have had no incident since but, i have not driven the car with low fuel. this could have had a very different result if i had not been able to get through the traffic on a busy interstate. both me and my wife could be dead. i believe there is a flaw in the low fuel warning software and something shuts the power. i have driven this car with lower fuel levels. the instrument panel shows miles to you have to refuel, i.e., 50 miles, 40 miles, 30 miles, 20 miles then ------. you have access to data on these cars, i don't. please have some advise me what is your thinking on this matter.

I bought the car and less than a month later the engine light came on. i took it into the dealership that i bought it from and they told me to take it to the subaru dealership if the engine light came back on. it never came back on. four days later i was driving and the gas pedal quit working. i looked down to see if any lights were on and they weren't. i pulled over to the side of the highway to turn the car off. before i could turn the car off i saw flames coming out of the front passenger side of the hood near the lights. then all of the warming lights came on. i quickly turned off the vehicle. before i could get out of the vehicle the whole front end of the vehicle was in flames.

Twice the forester surge forward --once it stopped before hitting a tree and the second time it hit a building. both times pulling in to a parking space from a road and from a parking area.

Engine hesitates on acceleration, especially from a dead stop, leaving me stuck in the oncoming lane for several seconds. this is a recurring problem and is very dangerous! it?s virtually impossible to accelerate without feeling hesitation and surging. it feels like the car is very slow to go into gear and then lunges to catch up. this happens in all weather and all driving conditions, it happens every day. very disappointing performance for a car i bought brand new.

Lost complete power at 70mph in center lane of expressway. shifted to neutral rolled to the side of the road. gas gauge showed 1/8 tank, 70 miles, no fuel light.. subaru said fuel pump overheated and that you should never drive with less than 1/4 tank. complete loss of power with no warning almost caused a catastrophic accident. vehicle was towed by aaa to subaru dealer. vehicle was unresponsive to aaa after sitting for 90 minutes waiting. dealer said fuel pump is cooled by fuel and running it when fuel is low causes pump failure. very casual, we almost died!. repair record attached.

Tl* the contact owns a 2015 subaru forester. while driving approximately 35 mph, the vehicle suddenly failed to accelerate when the accelerator pedal was depressed. during the failure, the instrument panel warning indicators illuminated and the check engine message displayed. the vehicle was towed to the local dealer (jones bel air subaru, 1317 bel air rd, bel air, md) where it was diagnosed that the accelerator pedal was faulty. the accelerator pedal was replaced and the failure was remedied. approximately two years and 12,000 miles later, the same failure recurred. the vehicle was towed to the same dealer where it was diagnosed that the accelerator pedal failed and needed to be replaced again. the contact was informed that the replacement pedal was a new and improved version. the manufacturer was notified of the failures. the failure mileage was 24,000.

I was approaching a light that turned green, and when i touched the accelerator, no gas. pulled around the corner, and put in park, engine revved high rpm. check engine light, xmode light, and another 'car on hill' light came on dash'..messages on display window 'hill start assist system' and 'emission control system' messages flashed. we turned everything off, started engine again, same thing, same messages. turned off again, restarted, and this time the gas pedal worked, but dash lights stayed on with warning lights. we were able to drive it about 5 more miles, then stopped for dinner. an hour later, the car started fine, no warning lights, no gas pedal issues. took to subaru west 2/25/16 where the technician hooked up his hand held computer thing to place near hood release. he said there was just one signal that told him it was probably from the fact i hit the gas and brake at the same time, and the vehicle senses this and shuts off the throttle. safety issue? i am a one footed driver, so not sure how that happens, but he said he cleared the computer and all should be good, but to bring it back in asap if the 'check engine' light goes on. hmm.

Occasionally stalls when accelerating (usually to get on freeway or speed up drastically while on freeway). doesnt completely lose power, only occurs for about 1-4 seconds but during that time car does not speed up even when pressing gas (actually acts as if foot was taken off gas), and makes a clicking noise. has happened ever since purchasing car new, and mentioned at every service but they can never recreate the issue and therefore cant fix it. saw a similar stalling issue on a recall for same type of car but not my vin. dealership wont check unless i pay fee.

On two occasions about a week apart, after slowing to make a right turn, the car suddenly lost all power mid turn for approximately 4 seconds. this caused the cars behind me to have to slam on their brakes & i was nearly hit both times. no check engine light came on. i called the dealer & was told the cvt causes pauses, however this was way too long & extremely dangerous. the service representative told me i could bring the car in for a test drive, but because it only happens occasionally it would be hard to duplicate. also if the check engine light didn't come on there would be no code.

I was very disappointed with my 2015 forrester.2.5i. intermittent loss of power of 4 seconds duration. dealer's service department states is normal and nothing is noted on the diagnostic history in the car. felt driving this was unsafe and took a loss and traded it in for a 2015 crv honda. i feel the public should know this, you need to check into this or /and do a recall or whatever is necessary. thank you for having this website. *tr

While driving eastbound on i-80 in iowa just east of exit 220 (williamsburg) our car lost power but, because it has a manual transmission, i was able to depress the clutch and coast to the left road margin. the low fuel indicator had come on a few miles before but the display indicator showed that we had sufficient fuel to drive 60 miles at the displayed average of 30.5 miles per gallon. this should have been correct as the manual states that when the low fuel indicator comes there are 2.6 gallons remaining. i tried to restart the car as the indicator continued to show one increment in the gas gauge and a range of 60 miles on the display. after several attempts it was apparent that the engine was not getting fuel. we eventually were assisted by an iowa state patrol officer who took me back to the casey's station in williamsburg where i bought a gasoline can and about 3.5 gallons of fuel. with his assistance i was able to fuel my car (the traffic at that time and place was very heavy and fast), and the car started immediately. it is be important to note that the low fuel indicator did not come on after i started the car. i had not put all of the gas in the can into my car, and the manual states that the indicator will not come on when the tank is holding 4.5 gallons of fuel, so there was clearly a gallon or more of fuel in the tank when it died. also, that section of eastbound i-80 is slightly uphill. it seems then that either the electronics associated with the reading fuel levels are very inaccurate, or the gas tank is built in such a way that when the tank is lower on fuel and going uphill gas is not getting to the engine. had i not been driving a manual transmission and able to roll onto the margin uphill but simply slowed to a sudden stop in that traffic when the engine died, i believe it would have caused a very serious series if collisions.

I'm having an issue with my 2015 forester 2.5i cvt that has nearly caused accidents, but when i took it in for service today i was dismissed without being helped. my car has about 24,700 miles on it, so it's thoroughly broken in and i'm used to the way the cvt works. in the past month or so, i've noticed bucking, shuddering, and power loss during initial acceleration from a stop. sometimes this is just a little bumping, but other times it's a near total loss of power for several seconds, long enough to be very dangerous while accelerating or especially while turning. when i took the car in for service, the advisor there started to tell me that the behavior is normal even before anyone had started to look at the car. after a tech took it for a test drive, the advisor told me that my concerns "describe a perfect cvt" and he doesn't see a problem, and that it's expected behavior to have dangerous power loss like this. i was told that my problem is not a problem and sent away. power loss like this during acceleration is clearly a problem, despite the claims of the subaru employees, and i do not feel safe in this car. subaru refuses to address this issue. the service advisor suggested that i avoid accelerating or turning any time power loss would be a danger or issue - this is clearly not an acceptable solution.

From a full stop, a/c on, i began to accelerate at a green light. car stopped acceleration at aprox. 2 miles per hour and coasted thru large intersection before accelerating again. i checked to see if the car was in drive and that the emergency brake was off. i took car to dealer who said no "error code" is available that would indicate a problem and they were unable to replicate the issue. obviously there is an issue because another driver made this same report. this is a huge concern for me because 1) what happens if the car fails again when i pull into traffic with my kid in the car? and 2) i bought a subaru because they are supposed to be safe and reliable. i'm seriously reconsidering my decision now.

Car was driven out of new car dealer without incident by driver with 50 plus years experience. approximately three to four miles into trip car experienced sudden unintended acceleration after going through a traffic light. car proceeded into wooded area and hit tree causing lower leg injuries to driver and moderate to severe damage to car. driver was not entrapped upon emt arrival. engine returned to normal idle speed. driver is confident car has problem with vehicle speed control and /or engine computer. car traveled at over 40 mph during incident and could not be stopped through normal braking action.

I had my new vehicle only 4 days with 120 miles or so that i personally put on it. i was out one day and came to a stop sign and stopped. the car just powered down to not running at all. i put it in park, restarted, put it in drive to move on and it did it again. i put it in neutral and had someone push me to the other side of the road where i would be out of the way. this continued for about 5 times when finally it took hold and i managed to get home ok. the next day i had to go out and it seemed to be ok and had to put gas in it. i took it in to the dealers on friday and told them about it so they kept it to find out what the problem was. got a call back today on monday 2-9-15 and they told me it was a faulty fuel pump. wow, on a new vehicle! said the part should be in on thursday due to being the only fuel pump anywhere near our area and the weather being iffy it would take longer. this was so unexpected of a highly rated vehicle. i had my pontiac vibe for 10 years w/ only a a/c problem once. with 130k miles on her i decided to upgrade to all the bells and whistles and now this. i am disheartening for sure. let's hope this is the problem and nothing more. thanks for listening. *tr

After i slow down to turn a corner this car occasionally pauses, or will not resume moving for a few seconds when i step on the gas. this has caused cars behind me to almost rear end me numerous times. it sometimes happens twice in one day then won't happen again for several weeks. i have taken it to the dealer but it has never done it on any of their test drives. this has occurred ever since i bought this car new. i was told other owners have complained of the same problem but they have to experience it when they test drive it.
