2018 Subaru Forester fuel system problems

Filed Aug 9, 2026 · Fuel system · NC

Discovered (06/08/26) that the engine would not turn over without the accelerator being pushed down when warm from driving after resting 30-60 minutes. Car was taken to Capital Subaru. No codes were triggered. The throttle body was cleaned. No change. The Crankshaft Position Sensor was replaced, the ECU was reprogrammed, then the EVAP Purge Valve was replaced. A bottle of fuel injector cleaner was added to the gas tank by the dealership mechanics. No improvement. Then both CAM sensors were replaced. No improvement. All with no effect. Finally the injectors were pulled and a rail pressure test was conducted. The injectors were not holding pressure for more then 2-3 minutes. The warm start issue was fixed when the injectors were replaced on July 31, 2026.

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 I was out of the intersection and along the roadside. I reflected on what had just happened a few minutes. Then I made my way back home 35 minutes slowly driving on back roads allowing cars to pass just in case it would happen again. Dealer told me there was extended warranty on fuel pump but he could not repair as he could not duplicate stalling. How many times do I have to stall in City trafficI or expressway before my fuel pump will be replaced? I had a kidney transplant that saved my life. I will not let a safety recalled fuel pump put me in danger again.

The contact owns a 2018 Subaru Forester. The contact stated that while driving at an undisclosed speed, the vehicle inadvertently lost motive power. The contact was able to pull to the shoulder of the roadway, where the vehicle was able to be restarted. After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the fuel pump. The vehicle was not repaired. After investigating the failure, the contact related the failure to the federal safety agency Campaign Number: 21V587000 (Fuel System, Gasoline), but the VIN was not included.

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 signs, the lights would turn off, but pop on as soon as I began driving again. I was able to make it to my destination and when I parked the car, it was shaking a lot while idling. It felt like the engine was about to die or shut off. It was late so I turned the vehicle off and left it parked for the night. The next morning, when I started the car, it was continuing to shake/sputter during idle and I drove it briefly to see how it ran. It continued to shake when pressing the gas pedal, however, the check engine lights were not on. Since I had to drive back home, I decided to take it slow and began the two-hour drive back. The engine again seemed like it wanted to die as I let the car warm up, but it did not shut off. Initially when driving, the car continued to have the same problem - shaking whenever I pressed the gas pedal, no matter the speed. The check engine panel lights did not come on, however, and after driving for about 20 minutes, the issue cleared up. I've only driven it as needed since then and it is currently running ok, but, given the numerous fuel pump recalls I'm concerned there is a defect with this model.

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 company and repaired by an auto body shop. My insurance rates will be increased because of the incident. There were no warning lights, messages or other symptoms prior to the episodes.

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. The vehicle has not yet been inspected and is available in my driveway for inspection. There was no warning or indicators leading up to this. In fact, the vehicle had just been inspected for an oil change at the dealership three weeks prior. This accident would have caused a fatality, mine, if not many others if there had been cars ahead of me or cars had been in the intersection or if the wheel did not break in time before merging with the freeway traffic. I am fearful to drive this car again. There were absolutely NO indicators leading up to this or right before it happened. The car simply took over and there was no control of it.

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 gas does not help. I took the first Subaru to CarMax for a check up but they found nothing wrong so I just returned it. I am taking the second one in in January. Because the problem is intermittent, it is hard to diagnose but there's definitely a terrifying problem. I thought I was going to die when I had that first one and now this one is developing the same problem. There are a few posts on Google about the same problem. Is there a recall? Have others reported the same problem? I would appreciate any feedback you might be able to provide.

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.
