On the 2023-2026 Subaru Outback, owners of recent EyeSight-equipped Outbacks report unintended, sudden full-force automatic emergency braking ('phantom braking') with no obstacle present — at highway speed, in fog, in construction zones (mistaking cones for vehicles), and even reverse AEB while backing up. A 2026 class action (Hall v. Subaru) alleges the system was improperly tuned to command full ABS-module braking whenever the cameras perceive a stationary object regardless of actual collision risk, citing 25+ NHTSA consumer complaints; one cited 2024 Subaru braked twice without input at 65 mph and was rear-ended. This is distinct from EyeSight camera/driver-monitoring warning faults — the hazard here is unwanted braking that can cause rear-end collisions.

Common Symptoms

  • Sudden hard braking with no obstacle ahead (phantom braking)
  • False forward-collision warnings
  • Reverse automatic emergency braking with nothing behind the vehicle
  • Braking triggered by fog, shadows, overpasses, or construction cones
  • Inability to fully disable the intervention

How to Fix

No recall as of mid-2026; an NHTSA-complaint-driven class action is pending. Subaru dealers can update EyeSight/ABS-module software and recalibrate the stereo cameras (recalibration is also required after any windshield replacement). Keep the windshield clean and uncracked, use OEM-spec wiper blades and correct tire sizes (out-of-spec items can degrade EyeSight), and report phantom-braking events to NHTSA. Drivers can temporarily disable Pre-Collision Braking via the EyeSight controls when the behavior recurs.

On the 2020-2025 Subaru Outback, owners across the 2020-2025 generation report recurring Driver Monitoring System and EyeSight-related warnings such as 'Driver Monitoring System Disabled' or temporary loss of driver-assist functions even in normal conditions. While some events are environmental, complaint patterns and service visits show that camera alignment, software sensitivity, interior camera faults, and related module issues can cause repeated warnings or feature shutdowns. This does not duplicate windshield cracking; the issue is the electronic sensing/monitoring system itself.

Common Symptoms

  • Driver Monitoring System disabled message
  • EyeSight unavailable message
  • lane keep or adaptive cruise disabled
  • frequent warning chimes
  • warnings return after restart

How to Fix

Diagnosis involves scanning ADAS modules for stored faults, checking for software updates, verifying camera visibility and alignment, and inspecting the driver monitoring camera and harness. Repairs may include module reprogramming, camera recalibration, replacement of the driver monitoring unit, or correction of low-voltage conditions that trigger false faults. If the windshield or interior trim has been disturbed, recalibration is especially important.

Owner tips & cautions

  • TipOwners recommend documenting the exact warning text and weather/light conditions with photos because intermittent ADAS faults are easier for dealers to address when reproduced clearly.
  • TipIf the windshield has ever been replaced or the battery disconnected repeatedly, ask specifically whether EyeSight and driver monitoring calibration/software updates were completed.
Typical repair cost:$150 - $2,000

Medium Confidence

On the 2020-2025 Subaru Outback 2.4L Turbo FA24 (FA24F / FA24DIT), the turbocharged FA24 (FA24F/FA24DIT) 2.4L boxer in Outback XT, Onyx Edition XT, and Wilderness trims uses port-less direct injection only, so fuel never washes the back of the intake valves. Carbon sludge accumulates on the intake ports/valves, typically becoming noticeable around 40,000-60,000 miles, causing rough idle, misfires, hesitation, and gradual power loss. Some owners also report elevated oil consumption on this engine, which accelerates deposit formation. Because no port injectors exist, fuel-additive cleaners do not reach the valves.

Common Symptoms

  • Rough or unstable idle
  • Cylinder misfire
  • Hesitation and reduced power
  • Check engine light (misfire codes)
  • Elevated oil consumption between changes

How to Fix

The effective remedy is mechanical cleaning — walnut-shell media blasting of the intake valves every ~50,000-60,000 miles (about $400-$1,200 depending on shop). Mitigate (not prevent) buildup with top-tier synthetic oil at shorter 4,000-5,000 mile intervals, top-tier fuel, and an occasional intake cleaner/Italian tune-up. Monitor oil level between changes given the engine's consumption tendency.

Typical repair cost:$400 - $1,200
