Recently reported ENGINE problems on 2017 Subaru Forester

While driving my vehicle wants to stall and i have to floor the gas pedal and it slowly starts to accelerate. i'm afraid that one of these days it will not accelerate and will cause a fatal accident. i brought it in to pine belt subaru in lakewood, nj for service and they said the software needs updating and they updated it. however, it's still stalling. this stalling happens many times. the last time was on 03/22/2019.

after full stop engine or drive train lost power on sharp left turn.resumed power in 2-3 seconds.engine did not stall and did not require restarting.has occured 5-7 times.

Driving in the freeway around 20-30mph, some traffic. on the way to dropping daughters off to school. on the freeway switched lanes then car lost power and decelerated on its own quickly from 20mph to about 1mph, pressing the didn't do anything. almost got hit by the rear driver behind me. managed to move to right lane. pressing the gas pedal did nothing, several lights on the dashboard appeared which included check engine light, traction control, oil light. turned off the car to find the number for towing about 15 minutes later turned on the car and this time pressing the gas pedal made the car go, dashboard lights still on. took the car directly to the dealership. dealer claimed it was a bad cell on the battery that caused the problem, and also reprogrammed the computer. bad cell on battery will not cause this to happen. dealer also failed to write the details of the incident. initial paperwork stated check engine light. advice dealer to properly document incident.

2.5 manual, burns oil at excessive rate. check engine oil light turned twice so far, once at 2k miles on a car and next time at 16k miles. both lights were well within the oil change schedule and the car has not been subdued to any unusual use. unable to travel in the car long distances without having 2 quarts of oil in a trunk due to possible engine failure for lack of oil. both times the low oil lights went up when traveling on roads and sunaru dealer had to add oil (still under warranty).

Screen blacked out everything went off, no lights, no radio, no dash board vision. this happened 3 times before i took it to the dealer. i was told it was an electrical issues and electrical cables were replaced, however, just this week my vehicle, while waiting at a light, turned completely off. it was so scary, good thing there was no one else behind me. a few minutes later i was able to turn the car on and continue my journey. now, i do not feel safe when i use my vehicle.

On 9/29/18, 1:35 pm while in the process of parking the vehicle and initiating a turn to the right the car suddenly accelerated from idle to full throttle unintentionally and launched itself towards a 12' x 20' wood framed outbuilding on our property which has an attached deck. before the vehicle could be shut off it had jumped up onto the deck and smashed into and partially penetrated the front of the outbuilding. forward progress was halted when the rear portion of the car had become high centered on the edge of the deck. presently the car is still on the deck and partially in the building. the right rear wheel is i" off the ground. the left rear wheel dug itself 3" down into the gravel. - no one was injured during this accident. the car was occupied by only the driver. - the airbag did not deploy even though the car experienced two (2) significant impact events. 1st when it hit a temporary wood step and the edge of the deck (18" above grade) and 2nd when it struck the building. most of the bumper was torn off the car when it hit the deck and is now pinned under the car. the impact shifted the building approx. 3/8" on it's post & pier foundation. - this report was written & submitted on 10/1/18. - a wrecker is scheduled to extricate the car from the outbuilding on 10/2/18. - the driveway and parking area where this occurred is crushed rock/gravel. - the distance from where the car instantly accelerated to the edge of the deck was approximately 22 feet. the face of the outbuilding is 8 feet from the edge of the deck. the distance covered by the car during this accident was approx. 30 plus feet. - during this event an attempt was made to control/stop the car with extreme application of the foot brake and handbrake and ultimately the stop button. - it was a dry, sunny, early fall day in the west side of the cascade mountains in washington state.

I did my first oil change at 1500 miles, then the next two changes at about 3000 mile intervals. then i decided to stretch them to the 5k miles recommended by subaru. i was about 4k miles into this change interval when my oil level light came on. i checked the dip stick and it was bone dry. i wouldn't have noticed oil consumption on the first few changes because i was doing them more frequently than needed and therefore the engine didn't have time to consume enough oil to trip the low oil light. i went to subaru for an oil consumption test, which it "passed". i documented everything and took photos of the dip stick before and after the test. subaru fills your oil to the top line of the dip stick. the mechanic informed me this is standard procedure. i was told that the amount of oil between the 2 lines is a quart. after the 1200 miles of the oil consumption test, the oil level was down about 20% between the two lines. taking that out to a full 5-6k mile interval, that means it burns about a quart or more in between changes. i spoke with the mechanic who said that this is completely within spec of subaru's standards. i told him i thought this was a lot, but he said this is normal for subarus in his experience. a car with only 16k miles should not require over a quart of oil to be added between oil changes. when my oil light came on again, within the same oil change interval as the oil consumption test (about 4k miles into the interval), i took the car back to subaru for a second oil consumption test. instead of performing this, they opted to replace my short block, a very extensive repair. i am still waiting for this repair to occur under factory warranty.

Our defective, now discontinued model, new 2017 subaru forester xt touring has broken down while accelerating on the highway twice due to a faulty piston thus leading to our engine being replaced. the first time the car was moving east on i-70 in colorado and luckily my husband was able to veer in the median of an exit ramp. the second time we were traveling east on i-70 again and luckily were able to pull off on the side of the freeway. this all began at 22,352 miles and to-date the "market value" of repairs has accumulated to $16,100.00. this same engine issue has happened two years in a row, yet a subaru representative [verbally, not written] mentioned to us that it is cheaper for subaru to fix vehicle by vehicle that comes in instead of issuing a nation-wide recall on our model. we were told our forester xt [mini suv] has the same engine that is in an impreza [four door sedan] which is not safe and is not right to the consumer.

After any driving in hot weather, smell of coolant in right side of engine compartment

Vehicle hesitates during acceleration, worse if ac is on. engine nearly stalls, losing power. initially happened during left turn and while vehicle is in middle of intersection in front of oncoming traffic. this is repeated issue over several months

I have a total of electrical power lost for 7 times. 2 times while driving i experience all electrical lost while driving on the highway. i was able to pull over to the side and was able to jump started the car with a jumper battery 5 minutes later. other 5 times it happened when i try to start the car and i did not get any electrical power at all. i took the car to the dealer twice and they change/fix the car ground the first time that i lost electrical power. then they change the battery after 5 electrical power failures. i am about to bring it in for the 7th time for them to look at it. i am totally lost confident and no longer feel comfortable or feel safe driving my two boys on this car.

Extreme hesitation from standing stop going straight ahead and turning. at 5 separate instances the car came to a complete rolling stop with no acceleration. after 5 to 7 seconds the car finally accelerated . when turning with plenty of room, for them, oncoming cars blared their horns, missing me by a few feet. someone is shurely headed for a hospital or funeral home on this problem. both nhtsa and subaru have been warned numerous times with no result for recall,repair or replacement. dealers are saying they can't find a problem. this problem has been ongoing for years now. maybe everyone's first stop should be at your state attorney generals office if we don't get results from either of you soon.

Upon starting, rpm surged to over 4500, and there was loud grinding noise, sounded as if the engine was destroying itself. sounded like severe metal to metal slapping with vibration that stopped when key turned off ignition. subsequent start appeared normal. vehicle had been sitting for approximately an hour at 30f, date of occurance 11/22/2017, 4930 miles since new. car was in a parking lot and was stationary. factory approved dealer service result "no problem found at this time". i feel as if its dependability has been compromised.

I was merging on i-95 at 4pm and it was raining, i was accelerating into the traffic pattern in the right lane when suddenly the accelerator would not respond, the car panel went black,no lights or info showed. i coasted off to the side of the road,the car was in drive,ignition on. the emergency light wouldn't go on, nor the bluetooth or sos call line. i shut the car down and into park and waited a couple of minutes and restarted the engine without a problem. if i had been in the middle lane or no where to pull off it would have been catastrophic . i took it to the subaru dealer the next day and they couldn't find a problem. told me it was probably a glitch, you can't afford to have a glitch at 70 mph. i no longer feel safe in this car, especially when i have my grandkids in the car.

Car stalls when making hard left turn with less than 1/4 tank of gas car was stopped and lurked left. could eaily repeat the problem in an empty parking lot. filled gas tank and problem dissapeared.

Tl* the contact owns a 2017 subaru forester. while driving various speeds, the vehicle lost power without warning. the vehicle was able to restart itself after a few minutes. the contact mentioned that the failure occurred on several occasions. the vehicle was taken to profile subaru (1323 nh-16, conway, nh 03818 (603) 447-3845), but the failure could not be duplicated. the manufacturer was notified of the failure. the failure mileage was approximately 1,500.

Forester - 500 miles - consistent and continuing problems: car lurches forward on its own in first gear. - in motion engine not only has excessive (can last 5 seconds or more) "rev-hangs" shifting up from any gear but actually increases by 700-900 rpms. this has caused difficulty in slowing down (reducing speed with downshift). when using brake to reduce speed when this occurs, the engine will begin to race, increasing up to 1500 or more rpms, difficult to control vehicle. - in motion 4th gear - stick shift vibrates excessively - so much so it is visible to the eye and seems like it will have to wear out from the friction, - in motion (intermittent) when vehicle dynamics control engages on upward incline a very loud (multiple) banging occurs at the rea car lurches . - turning, in motion. engine noise is extremely loud compared to other 2017 foresters i have driven.can sound like it is ready to throw a rod in the near future - in motion and stationary subaru states all is normal. service manage at dealer states loud engine is definitely not normal for the 2017 model and he experience the excessive rev-hang but doesn't know what to do these things because subaru says this is normal are normal.
