2018 Subaru Outback: false forward collision warnings

Filed Jun 5, 2026 · PA

I am writing to report a severe, escalating safety defect regarding the "ghost touching" / phantom input malfunction of the infotainment head unit on my Subaru Outback. This electronic defect has escalated from a minor distraction into a severe hazard that directly compromises the operational safety features of the vehicle, putting myself and my children at imminent risk of a crash. When this problem initially began, I investigated whether a safety recall had been issued. At that time, I was informed that my vehicle was outside of its standard warranty coverage period. Since then, the defect has degenerated significantly. The system now suffers from continuous, uncontrollable phantom inputs ("ghost touching"). Even when I manually power the radio off, the system overrides my command, turns itself back on, and initiates constant, rapid beep sequences. This continuous, high-volume auditory glitch creates a dangerous critical safety failure: the nonstop beeping totally masks and completely drowns out the vehicle's actual auditory collision avoidance and driver-assist safety alerts. Because of this defect, I am entirely unable to hear the safety tones meant to warn me of immediate hazards, including blind-spot detection alerts, lane-departure warnings, and cross-traffic alerts. This vehicle has become an active hazard to drive, as I am deprived of the core safety features I rely on to protect my family. I contacted Subaru of America to resolve this dangerous equipment failure, but they refused to offer any financial assistance or repair support. Subaru Corporate documented this refusal under Subaru Case #260603-1600711. Because Subaru refuses to address a known component failure that actively disables crash-avoidance warning systems, I am petitioning the federal safety agency to investigate this defect as a systemic safety hazard before it results in severe injuries or a fatal accident. I can share video, but it won't allow me to upload down below. Thank you.

Report on Accident [XXX] 4TH DISTRICT wHEATON MARYLAND [XXX] [XXX] I was driving west on [XXX] at approximately [XXX]. As I approached the intersection at [XXX] the TRAFIC light cars were stopped . I was in the left hand lane because I was going to turn on to [XXX] . As approached the intersection I applied the brakes the pedal went close to the floor but the car did not slow down. I tried pumping the brake pedal with no effect. No collosion avoidance alert To try and slow the vehicle ran the wheel against the curb of the median which slowed the car down a little . I pressed the parking brake button with no effect. The collision avoidance system did not engage. I clipped the rear of the Toyota Corolla as I jumped the curb to avoid cars using the friction against the curb and move further left when oncoming cars were clear and was able to stop the car. (The car may have stopped because the front control arm bent which made the car drag. ) I am unsure whether the master cylinder failure or ABS overrode braking, but the car would not stop. I do not know if the black box captured the data as the there was no airbag deployment. The collision avoidance system did not engage to slow the car any time. I did not see any lights light on the dashboard did not check specifically as I was busy avoiding a collision other cars . Basically, pedal went down not all the way to the floor but car was not slowing down. I checked the master cylinder reservoir, and it still had fluid.

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. I am unsure what component failed to cause this issue; car is available for inspection on request.

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. Air bags did not deploy and the owner suffered minor contusions causing pain and stiffness, but no significant injuries are noted as of this report. The vehicle was totaled and significant damage was caused to the residence. No collision warnings were displayed prior to collision and emergency braking did not apply upon acceleration. This was the first incidence of sudden acceleration experienced by the owner so this issue has never been checked out by a service technician and will not be repaired. The vehicle had less than 8000 miles on the odometer. The vehicle is currently located in a repair lot and the owner’s insurance company has been requested to hold the vehicle for inspection prior to disposal. The cause of the sudden acceleration is unknown, but the owner is confident that the brakes were being applied at the time of occurrence, and that they remained cognizant throughout the incident as they were unable to stop the forward progression of the vehicle until it came to rest on the muddy incline.

I experienced premature draining of my car battery. I purchased the car in March 2021. It had approximately 19K miles and was in excellent/showroom condition. This is my first car with GPS and other advanced driving assistance safety features and collision avoidance systems. I'm still trying to understand all of these but some seem to have a mind of their own. I discovered the car's battery dead on the morning of 11/14/21. There was no warning that there might be a low battery problem and the car worked fine the previous day. I researched on-line about why this would suddenly happen and came across the Class-Action Lawsuit filed in April 2020 regarding these problems with Subaru Outback and Ascend models. I will also be contacting the legal team involved with the lawsuit, McKenzie Lake Lawyers, to verify if I need to take any steps prior to having my car fixed. Because Subaru of America and its dealerships deny there is a fundamental problem with premature battery draining, there is no verifiable source on how to repair the car, outside of simply replacing the battery, or how to reset the associated memory features. I have no idea of what electronic and safety features will or will not be operating properly once I replace the battery. I'm also very hesitant to take the car on a long trip over the Thanksgiving Day week.

The car windshield suddenly cracked on its own without any external or internal impact while parked. The crack started from the top on passenger side and extended vertically to the middle of the windshield. This crack impaired the ability of the eyesight driver assistance system to function properly causing the vehicle to lose safety critical features like forward collision avoidance and lane keep assist.
