2018 SUBARU FORESTER Fuelpropulsion System Problems

Yesterday 6/19/25 I was driving out the driveway when the vehicle accelerated on its own, and not slowly, but like it had been punched. I was actually coasting at the time since I didn't want to stir up dust. My foot was not on the gas pedal. And it was not the floor mat. It happened on its own, the first time in 87,000 miles. It probably cannot easily be replicated as it was completely random, although now that it's happened once, it very well could happen again if there's a faulty or aging part or sensor. Neither the local dealer nor Subaru has acknowledged the problem (I called both today) but it's a SERIOUS safety issue. No check engine light or other means of warning. It just happened out of nowhere. Glad I was in the driveway and not in town waiting while a pedestrian was crossing the street.

Fuel Pump. Stalled in intersection in middle lane at expressway entrance. Car stalled 3 x before I could move out of intersection to safety. Kept pressing gas peddle but car would not move then sputtered going a few feet before stopping again. 3x Cars were going thru light and around me at 45 mph. Honking, swerving into other lane, barely avoiding hitting my car as well as other cars.

2018 Subaru Forester stalling in intersection Prior there was an occasional delay in starting. After light changed I was starting to move down a hill toward expressway entrance at about 25 mph. I was in the middle lane and all cars were coming behind me at 50mph. I just entered the intersection when my car just stopped. It would not move. I was trying the gas pedal but car did not move. Suddenly it began jerky movements, moved a few feet, sputtering and stopped again. Now I’m in the middle of the intersection. I looked in my rear view mirror and saw cars speeding down hill, honking as they went around me. The car repeated jerky movements, moved a few feet and stopped again. I was still in the intersection and light was about to change. It finally repeated the jerky movements, etc until it stopped a third time. Fortunately...

The initial incident happened when I was accelerating uphill. When I pressed the gas pedal to accelerate, the car began jerking and sputtering. I released the gas pedal and let the car coast, as I was heading toward a stop sign. After I stopped and then accelerated the second time, the engine seemed to smooth out. Nothing further happened until about 1 week later. The second incident, I was 35 minutes into an hour-long drive. I was going around 45-55mph when the same issue happened suddenly: I pressed the gas pedal and the car started shaking and sputtering. If I released the gas pedal, the car was fine. All check engine lights came on and were flashing. I lowered my speed into the 30s, and the issue continued to happen, regardless of what speed I was driving at. If I was accelerating, the car was shaking a lot. At stop...

Twice in the last 4 months, after turning into a parking place and accelerating gently to pull forward into the space, the car surged forward much more than it should have given my light acceleration. The first time this happened I slammed into a split rail fence which broke, damaging the vehicle. The fence parts went over a restraining wall and damaged a house. I was able to stop the car but it came very close to going over the 6 foot restraining wall, which might very well have killed me. It happened again today in a different location but similar circumstance and no damage was done because I was able to stop before it hit the house. The car surged on its own. I had the damage to the car fixed, but the problem has not been confirmed by a service center. The damage was inspected by my insurance...

I was the first car stopped at a red light of an intersection coming off the freeway, in far right lane. When the light turned green, as I released my foot off the brake and not even stepping on the gas the RPM surged with full force accelerating without my foot on the gas. I stepped on the brake but it would not engage - it locked. The steering wheel locked and only had minimal movement, as much movement as you would get in a parked position. There was no way to stop the car. Given the lane position and obstructions ahead (freeway on ramp), the car ran over a median and scraped along side the curb and on top to damage the front passenger wheel enough for it to pop. Only when the wheel broke did the car’s brake re-engage and I was able to put it into park....

In June 2022 I purchased a 2018 Subaru Forester Turbo Touring at Carmax. Soon after purchase the car hesitated a few times when I was turning. I was turning in front of oncoming traffic and it scared the ___ out of me. So I returned the car to CarMax and bought a similar replacement which is the VIN reported to you in this report. After a couple of months, this car is now doing the same thing , generally when turning but sometimes when merging into traffic. I press the gas, the car moves a bit, then it just dies - there's nothing there, simply no response. It does not turn off, it is just powerless. Then a few seconds later it gets gas and we squeal to safety. However I am just dead in the water, usually in front of oncoming traffic, until it decides to move. Pumping the...

I recently purchased a used Subaru Forester with about 92k miles. About two weeks after purchase, I took it to a Subaru dealership and a multi point inspection revealed a cracked catalytic converter. The tech stated that this was discovered by visual inspection. This failure causes a safety issue by leaking exhaust vapors into the cabin. This failure occurred with no warning lamps or messages/codes.

I took our 2018 Subaru Forester through a car wash. The usual washing procedure went just fine with me in the car idling in neutral as it went through. When it came to the end of the wash cycle, I coasted out and then shifted into drive. Instantly the car surged forward at an alarming speed and I could not stop it. The car crossed a busy street. I fortunately did not collide with cars. The car continued into a field next to a Ford dealer’s lot at a high speed and I was unable to stop it. I managed to swerve right to avoid crashing into the cars parked on the Ford lot. This sent the car back toward the road. Fortunately I hit a lone fire hydrant along the road, shearing the hydrant completely off. The hydrant was dragged along under the front left tire until it hit...

While turning in a parking lot car accelerated and hit a tree. Foot was on brake and airbags didn’t deploy despite extensive damage. Body shop estimator said computer wouldn’t confirm problem. It was not caused by floor mat! No warning lights prior to incident.

At around 35,400 miles on the odometer, the vehicle first started backfiring as I was driving. I began an uphill climb through low mountains and the check engine light began flashing, the "emissions control systems" warning light came on the screen, the engine began seriously sputtering and lost a lot of its power, all occurring at the same time. Luckily I have a standard transmission and was able to downshift through gears to regain some power and was able to drive 10 miles, seriously sputtering the whole time, to a safe location. I turned off the engine and it wouldn't start back up again, therefore, I had to have it towed home. The next day I had it towed to a Subaru dealer. It took them 5-6 days to diagnose the cause and fix. I was told it was a VERY rare occurrence; it was pinpointed to the fuel injector...

The 2018 Forrester XT was taken to Subaru Dealer (Gwinnett) for a routine 42,000-mile service. There were no issues with the car. Shortly after picking up and driving approximately 30 miles the car stalled twice at traffic lights. The engine was restarted but started to exhibit sluggish and erratic acceleration, especially from 0-45 MPH. The car was taken back to Gwinnett Subaru the next day. They did some data retrieval and found a mass airflow event, cleaned the air filter, test drove the car, and released it to us. The next few days, the same problems were experienced but the car did not stall. At one point, at a traffic light, the car would simply not accelerate even with full pedal pressure which was gradually increased. When it finally did, it was uncontrolled and erratic. Highway driving once speed was reached seemed normal, but any acceleration from a slower speed...

When applying gentle gas pressure at low speed car does not respond for 2-4 seconds, then lurches strongly forward as tho full throttle has been applied. Happens at random times. Dealer said nothing wrong when first happened 2 years ago. Was rare until today when it happened 6 times within 50 miles of city driving. Will see dealer tomorrow. No warnings of any kind. Grave safety hazard as could be hit by traffic when trying to enter street or get out of somebodies way when car does't respond.

VEHICLES DRIVER SEAT RAIL HAS BECOME LOOSE CAUSING SEAT TO SLIGHTLY MOVE WHEN LAYING BACK.. COULD BE HAZARDOUS WHILE DRIVING.. AT INITIAL TAKE OFF, ACCELERATION JERKS, ACCELERATION IS NOT SMOOTH, AFTER SLIGHTLY PRESSING ON THE ACCELERATION PEDAL, I HAVE TO SOMETIMES BRAKE BECAUSE ACCELERATION IS JERKY AND ROUGH. I JUST PURCHASED THIS PRE-OWNED 2018 SUBARU FORESTER WITH 14K MILES AND IT IS ALREADY BLOWING SMOKE AT START UP.

AS IT STANDS IN P (PARK) IT HAS A REALLY HIGH IDLE EVEN IN NEUTRAL AS IF IT WANTS TO GO. THEN IN DRIVE IT WILL LURCH REALLY FAST. OR I HAVE MY FOOT ON THE BREAK AND IT STARTS TO REV HIGH THEN AFTER 3-5SEC OF SEEING REV CYCLE IN THE 2000-3000S IT CALMS DOWN. I ALMOST REAR-ENDED A CAR YESTERDAY. IF YOU SLIGHTLY PULL OFF THE BRAKE THE CAR WILL WANT TO JOLT FORWARD. WHEN IT REVS HIGH AND I TAKE MY FOOT OFF THE BRAKE IT JOLTS FORWARD THEN SLOWS AS IF IT RECOGNIZES I NEVER HAD MY FOOT ON THE ACCELERATOR. IN ALL OF THESE TIMES I NEVER HAD MY FOOT ON THE GAS PEDAL. I DON'T HAVE PICTURES BECAUSE OBVIOUSLY IT'S SCARY AND I'D RATHER FOCUS ON THE DRIVING THEN MY CAR ACTING STRANGE. BUT I REALISED THAT WHEN THIS WAS HAPPENING MORE AND MORE...

STRONG FUEL ODOR IS DETECTED IN GARAGE AFTER PARKING AS WELL AS WITHIN THE CABIN WHILE DRIVING. BELIEVE FUEL IS ENTERING OIL FROM UNDETERMINED LOCATION AS ODOR IS ESPECIALLY PRONOUNCED AROUND DIP STICK. IF OIL IS CHANGED THE ISSUE DISSIPATES BUT RETURNS WITHIN 1000 MILES. THERE ARE PLENTY OF ONLINE REPORTS FROM OTHER 2015 - 2018 FORRESTER XT (TURBO) OWNERS REPORTING THE SAME ISSUE AND IN MOST CASES THEIR DEALER IS UNABLE TO DETERMINE AN ISSUE OR PROVIDE A SOLUTION. IN ONE REPORT, HOWEVER, THE OWNER INDICATED THEIR DEALER FINALLY RESOLVED THEIR ISSUE BY REPLACING A FAULTY INJECTOR SEAL.

TL* THE CONTACT OWNS A 2018 SUBARU FORESTER. WHILE CHANGING THE OIL IN THE VEHICLE, THE CONTACT NOTICED FUEL INSIDE THE ENGINE OIL. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE CONTACT NOTICED FUEL FUMES INSIDE THE VEHICLE. THE VEHICLE WAS TAKEN TO SUBARU OF CORVALLIS (LOCATED AT 800 NW 5TH ST, CORVALLIS, OR 97330, (541) 754-1515), BUT WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 6,000.

WHEN ATTEMPTING TO ACCELERATE TO MAKE A LEFT-HAND TURN THE CAR STOPPED - THE ENGINE WOULD NOT GET ABOVE IDLE, EVEN WHEN THE ACCELERATOR WAS PRESSED TO THE FLOOR. THE CAR STOPPED IN ONCOMING TRAFFIC. IT DID ACCELERATE AFTER COMPLETELY REMOVING PRESSURE FROM THE PEDAL AND PUSHING IT PARTIALLY DOWN AGAIN IT BEGAN TO PICK UP SPEED.
