I was going 55 mph on a straight flat surface when all of a sudden the RPM's shot up to around 4000 but the car was not accelerating. It was like it went into neutral. I pulled over to the side of the road and the car proceeded to die. Fortunately, it started right up and I drove home. I had a almost a full tank of gas. I had only driven it for 5 minutes as I was on my way home from work. I just had the oil/filter changed not even 2 months ago. I have 54,000 dealer serviced miles on the car. It was 86 degrees out. 2015 Subaru Outback premium 2.5

Noted over a period of several weeks, an increase in exhaust noise from the front of the car. The cabin would fill with exhaust fumes when stopped with the engine running. I took the car to the dealer twice to have the issue diagnosed and both times they indicated that no issue was found. On the third trip, they confirmed a hole in the exhaust manifold and initially refused to replace it under warranty, even though the vehicle was covered under the pzev emissions warranty and extended vehicle coverage. After pointing out the pzev coverage, the dealer replaced the manifold.

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.

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.

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.

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.

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.

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.

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.

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.

Outback

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.

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.

Outback

  • 100 miles
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

Outback 6-cyl

  • 25 miles
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 updated 11/07/2017
