Owner reports

Selected complaints filed with NHTSA by 2018 Subaru Forester owners, lightly cleaned up (personal details are redacted by NHTSA).

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. …

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 the curb stopping the car. The air bag did not deploy and I was not injured. This all occurred in a matter of seconds.

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 NHTSA Campaign Number: 21V587000 (Fuel System, Gasoline), but the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 69,000.

The contact owns a 2018 Subaru Forester. The contact stated while driving 30 MPH, the vehicle started shaking abnormally. The contact pulled over, stopped, turned off, and restarted the vehicle. After the vehicle was started, smoke started coming from the vehicle while several unknown warning lights illuminated. The vehicle was towed to the dealer to be diagnosed. The contact was informed that the spark plugs needed to be replaced. The vehicle was then taken to an independent mechanic and the contact was informed that the fuel pump needed to be replaced. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was approximately 38,000.

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.

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. …

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 and coil, they went bad in cylinder #1. …

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 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. …

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. …
