2018 Subaru Forester acceleration problems

Filed Dec 4, 2023 · Acceleration, Fuel system · MA · crash

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.

While reversing out from a drive way and turning to get into the lane the cars velocity massively increased from no throttle coasting to approximately 20 mph. Panic braking and enough space due to it being a cul-de-sac saved us, but we were launched forward in our seats and slammed back during breaking. we were very fortunate not to have anyone or anything behind us as we nearly went over a curb and into a lawn. A very scary experience that has cast doubt onto this vehicles driving suitability.

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.

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.

Follow up-to complaint #11420905 submitted 6/14/2021. The car was taken back to the dealership due to stall, hesitation, slowness, and erratic uncontrolled acceleration. Safety was the main issue. The dealer confirmed the concern and replaced the transmission with a remanufactured one. The problems still remain with the exception of the stalling. We believe this situation requires further thorough investigation and possible recall or new transmission installation.

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 was problematic. On Monday 6-14-2021 the car was taken back to the dealer due to serious concerns about safety and the possibility of the loss of power when critically needed or when on the highway. The dealer promised to investigate the problem further. That evening, we were informed that it was their assessment that the car would need a brand new CVT transmission. The car has approximately 41,100 miles and we were told that it would be covered by the 5 years/60,000 miles powertrain warranty. Expected to take 7-10 days for repair.
