Selected complaints filed with NHTSA by 2018 Subaru Outback owners, lightly cleaned up (personal details are redacted by NHTSA).
I was backing out of my driveway very slowly as usual. I checked the road both ways several times. A US mail truck evidently traveling at a high rate of speed came up behind me while I was looking in the opposite direction. The automatic braking did not kick in, the warning system didn't work. After the accident the green, yellow, red lines on the camera and the warning beeping stuff-all were not working for several weeks. All of the sudden, they started working. HISTORY-4 days after purchasing the vehicle we have had lane departure, driver assist problems. The passenger window does what it wants. The electric controls for the heat/ac go blank, or can't change settings. There seems to be a huge electrical issue. Every time we've taken the car in for service, the dealership just insults me that I can't drive and they can't find any problems. …
The contact owns a 2018 Subaru Outback. The contact stated that the Eyesight system had become inoperable. The vehicle was taken to the dealer, where the system was recalibrated. The vehicle was repaired. Additionally, the contact stated that the infotainment system screen was delaminated, causing the touchpad function to become inoperable.

Additionally, the contact stated that the infotainment system screen delamination had caused the infotainment system to activate vehicle functions independently. The contact stated that the rearview camera was still operable. The dealer was notified of the failure and informed the contact that it was a common failure. The dealer related the failure to an Extended Warranty. The vehicle was not diagnosed or repaired. …
Car jerked back and suddenly accelerated without warning as driver had foot on brake and was slowly pulling into parking spot. Car hit wall of parking garage causing front end damage. Parking collision warning did not sound at any point. Car was going 1-2 MPH and was 5 feet from end of parking spot when incident occurred. Sudden acceleration when driver has foot on brake can cause injury to driver, passengers or others in the path of the car. No hazards in parking garage were present that could have caused accident, which was witnessed by driver's work colleague. No police report filed. Incident was reported to Subaru, which ran diagnostic and could not replicate issue. No warning messages were present prior to the incident. It appears there are 2 current class action lawsuits filed against Subaru reporting similar issues with 2018 Outback. …
Driver experienced an unexpected uncommanded sudden acceleration upon application of the braking system in the driveway, which caused a collision with the garage/house.

While pulling into a parking spot with my foot on the brake and preparing to stop, the car continued to move up over the curb and then began to accelerate even after I applied both of my feet pushing down on the brakes until I hit our condo building. The car and building received extensive damage, and although the car was not totaled it will cost over 7,000 dollars to repair. Personally I was not injured. The air bags did not imploy at impact. There were no warning messages or prior failures with the vehicle before this day. The car was taken to a body shop and not the dealer so we have not had the dealer look at the systems that broke down, but our insurance adjuster will be.

The vehicle, a 2018 Subaru Outback Limited 3.6R, was being pulled into the garage at the owner's home. With brakes applied, and while putting vehicle into park, the vehicle suddenly accelerated forward making contact with a suspended shelf attached to the back wall of the garage. The force of the vehicle was such that the shelf and back wall of the garage were completely separated from the home in one piece and pushed approximately 10 yards away from the home before the shelf broke away from the wall upon impact with the ground, perpendicular to the back of the house. The vehicle then traveled down two hills in the back yard, across a water saturated easement, over a concrete drainage culvert and came to rest at the base of an incline in an adjacent yard approximately 150 ft from the garage. …
The battery in my 2018 Subaru Outback has been replaced three times since I purchased it. I am the sole owner. The original battery was replaced within seven months of purchase due to continual battery drainage. The dealership replaced it with the same type of battery and I was not charged. When I went into the dealership expressing concern with the second battery also having to be jump started frequently when the battery was barely two years old, I was told that is the typical life of a battery for the newer electronic vehicles and because the area I live in has excessive heat, that also lowers the battery life. I have had to jump start my vehicle so many times, I stopped taking my vehicle on long trips for fear of being stuck somewhere. In August of 2021, during a cross- states road trip, the battery died mid-trip. …
