Problems with 2015 Subaru Outback ENGINE

On average, the 2015 Subaru Outback starts to “feel” problems with the ENGINE and its various aspects after 25 084 miles.

Recently reported ENGINE problems on 2015 Subaru Outback

Vehicle would not start. after jumping the battery vehicle started, aaa performed roadside testing and determined the battery and alternator are working properly and are sufficiently charged. car would not start for unexplained reasons. previous service history leads me to believe there is an ongoing electrical issue with this vehicle. previously the airbag light would frequently illuminate. dealership stated it was due to electrical interference and that nothing was wrong.

Exhaust system issue. exhaust mainfold leak at catalyst converter. for our outback we noticed a significant levels of exhaust fumes in passenger cabin. they were no indication of failure of exhaust system or catalyst converter on the car. but we are getting some much fumes smell when we stopped at the traffic signal or parking lot. it all most made us sick. luckily i got it checked at the service center and they find the leak. this is potentially a very risky thing for people who don't notice the smell might get slow poisoned with carbon monoxide or other elements in exhaust fumes. there may be direct injury from this issue but as i said i was almost got sick because of fumes. for people with pzev vehicle, the exhaust system is covered under warranty. please bring this issue with manufacturing. for people out there if you notice a loud exhaust note at start of your vehicle or small rattling noise when we you accelerate after a complete stop, it might be your exhaust system, please get it checked as soon as possible. ps attached is the diagnosis report from dealer service center be safe out there !! thank you.

We noticed an exhaust leak (noisy) on our 2015 outback, upon inspection by the dealer they determined the catalytic converter needed to be replaced, they initially rejected our warantee claim because subaru authorizes replacement only if a mil is present. after some discussion the dealer (subaru) agreed to replace as "good will". we live in the northeast and it seems road salt and sand cause the converter to rust prematurely, the location of the converted is aft of the exhaust manifold and at the base of the passenger compartment, there is a risk of carbon monoxide poisoning with these types of leaks, and it is unheard of that these parts fail after three years.

Please read upload documents. my 2015 subaru outback began showing signs of excessive oil consumption in the summer 2018. apparently this was a known problem with subaru and class action lawsuit was filed against subaru for models made prior to 2015. my vehicle failed a oil consumption test in the fall of 2018. i was told by white bear subaru if the vehicle failed an oil consumption test subaru of america would pay to have a new short block installed due to this ongoing engine defect. however, subaru of america refused to pay the full amount to have a new short block installed as even though my car was make in 2014 it is technically a 2015 that the class action lawsuit only protected consumers of models prior to 2015. also, in the fall of 2018 the interior of this vehicle began to have a exhaust smell and was making me feel sick. they determined that part of the exhaust system was broken but told me not to have it fixed before the new short block was installed and the exhaust system would just become clogged with the oil the car was burning. i went ahead had had the repair done anyway as the exhaust air was terrible.

While parking the car at an open parking lot in shopping center at low speed (<5mph) the engine surged suddenly and the vehicle accelerated uncontrollably. it required tremendous pressure on brake to eventually override the engine.

Excessive oil consumption between oil change. when the vehicle reached to 45,000 miles, the low oil light is on less than 5,000 miles between oil change. if the driver ignore the warning and not add oil to the vehicle, the engine can be damages. a three years old vehicle with 45,000 miles should not have to change oil freqently. i spoke to the dealer, they said the oil level is normal, and oil consumption test is not needed. when i took the car to a car repair shop, they told me the oil level is lower than standard between oil change. i also contacted subaru north america, was told that my vehicle is not covered by the class action settlement, and only a very small number of customers have identified a concern on this issue.

Excessive exhaust entering passenger cabin anytime the engine is running because of crack in flex pipe on the exhaust manifold that occurred with less than 60k miles.

The car would stall when coasting to a stop light or stop sign a few times and have been back to the dealer and can't replicated the problem. this is a dangerous situation and can cause an unsafe and huge accident with my family. the car would die while in drive and sometimes can't be restarted. it's happening again and afraid to drive the car since the dealer will say nothing is wrong with the car. it looks like it's related to idle being low or the cvt acting up when taking the foot off the gas pedal and try to accelerate from a dead stop or coasting to a stop. this happened a few times during factory warranty window.

2015 subaru outback. consumer writes in regards to rough idling in vehicle. *ld the consumer stated the vehicle annoyingly vibrated when the air conditioner was on. *js

Very difficult to start-problem with push to start button and engine not getting fuel. vehicle stationary in parking lot. have had to get jump start 3 times

After 2 years of ownership on my brand new subaru outback 2015, i have noticed a loud squeaky sound coming from the engine when i start my car after it rained/snowed. the sound would go away after a few minutes, however, it didn't seem normal. i took the car to the dealership to have it checked out. the dealership told me that nothing is wrong and it is perfectly fine. however, the squeaky noise still occurs after rain/snow. it seems to me that water is leaking into a belt when it's not suppose to and it is causing the noise when the engine is started. subaru needs to look into this issue because this problem only happens after it rains/snows and cannot be replicated when the car is brought to the dealership. therefore, it is hard to have this issue fixed.

The subaru outback 2015 was parked in a lot after a 12 minute drive and burst into flames. it was purchased in february 2015 and was not yet due for servicing when the event happened. the subaru outback manufactured from july 3rd-27th 2015 has been recalled due to "possibility of fire due to a transmission fluid leak". i believe the same thing occurred with my car and i am concerned that if the model is not recalled someone will get badly injured or killed due to fire.

Unintended acceleration. when driving at low speeds--what would traditionally be 1st and 2nd gear (the car has a continually variable transmission)--and while keeping constant pressure on the gas pedal, the transmission changes the acceleration of the vehicle on its own in a process that feels like it can't find the right "gear", and it provides a "jerking" feeling (usually only a couple of "jerks"). yet the transmission is not just finding the right gear for a specific constant speed; as it shifts around, the acceleration changes and has, with constant pressure on the pedal, accelerated faster on its own. i have never felt less control of a vehicle as i have with this one.

I have a surging issue with my 3.6r after cold starts. upon start-up, the idle will be ~1800 and when i put the car in drive, it will drop to 800-1000rpm. then, as i slowly pull into the garage, or pull into a stopped line of traffic, the engine will surge back to the higher rpm, causing the vehicle to push through the brakes. i have had this return to high idle occur after i have come to a complete stop, causing the vehicle to push through the applied brakes and requiring additional brake pressure to stop the vehicle. i have also had it occur when slowly rolling forward. i believe this is an unsafe situation that could result in damaged property and/or injury. i see that there is at least one additional nhtsa complaint for this issue, which subaru deemed "normal" operation. i did contact my dealer requesting a firmware update, if one was available, and they said there was not one. i have owned this vehicle since 3/23/2015 and this issue has occurred since new, but it more common in colder weather. i have 18k miles on the vehicle.

Dear sir, on february 11,2015 we purchased a new 2015 outback 2.5 premium at seller dealer 400106 vin [xxx] and the odometer reading was 10 miles. this was our dream car that we saved for a few years to finally purchase. it developed an engine knocking noise at only 1000 miles on the odometer. so i took it to the subaru dealer for evaluation on 3/18/15 and after 2 days there they determined that the engine had a problem and would have to be replaced according to subaru experts. i really respect subaru??s and their history, but we no longer consider this one our dream car. if the power plant is faulty we wonder what else is going to go wrong with it. my family will no longer feel safe. though the car may or may not fall under the song-beverly consumer warranty act we want a replacement for the same type vehicle, nothing more and nothing less. i feel the engine should not of failed at only 1,000 miles on it and i'm sure [xxx] would strongly agree. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

Two issues; the similarly reported electrical stop. started car on cold morning, drove short distance, dropped kids off at school. went to restart, and car was completely dead. had to jump it. second issue; burning oil smell in cabin. oil level was fine, and smell not coming from tail pipe. took car to shop today for the oil smell, and i told them about the electrical stop. they said the electrical issue is related to needing to replace 4 relays. the oil smell, however, is due to a bad crankcase seal that they said failed most likely due to the cold. i found similar reports on subaruoutback.org/forums/

Engine idle is erratic when cold. backing out of the garage in the morning the engine surges 3-400 rpm making the car jerk faster and slower. this is with only the brake pedal pressed. i have a second identical car that does not have the problem. temperature is in the 40's. when the engine slows, you have to ease off the brake, them it suddenly speeds up 50% and the car takes off. the cycle repeats for a few minutes in the mornings. the problem is very repeatable -the same thing every morning. *tr

Red engine light came on and car died. lost all power/ drive. needed to coast to berm. would restart, but die immediately. everything was immobilized. this could have happened at 70 mph on an interstate! our was very close to being rear- ended. *tr

The vehicle is equipped with the 3.6r engine and a continuously variable transmission. when descending a long hill in a fixed gear ratio (usually 2nd or 3rd) the vehicle slows normally until the rpm reaches approximately 1200 rpm at which point the vehicle suddenly begins accelerating until the rpm reaches approximately 2500 rpm at which point the process repeats. i observe the "mpg" suddenly drop at the same time to around 25 mpg when the vehicle accelerates. it rises back to "99" when it slows. note that during the entire sequence my foot is off the accelerator pedal and the throttle angle display shows zero. i find this very hazardous as the unintended acceleration can occur when entering or within a turn creating a crash risk. upadte 9/15/15*cw

When the engine is cold, the idle speed is 1600 rpm when started. when placed in reverse or drive it reduces to a nominal 900-1000 rpm. when the vehicle starts to move it suddenly drops to 600 rpm. when braking to a stop after moving vehicle the rpm suddenly jumps to 900-1000 rpm just before vehicle halts. this causes sudden unexpected acceleration of the vehicle and presents a safety hazard. i believe this is due to an engine/transmission software issue. this has occurred since new. updated 9/15/15*cw updated 11/07/2017*cn
