Subaru Forester persistent tailgate beeping issue despite multiple part replacements on Subaru Forester

Some Subaru Forester owners report experiencing persistent tailgate beeping issues despite multiple part replacements. These beeping sounds may be linked to various features, including the navigation system, Eyesight driver-assist features, or a key fob left inside the vehicle, and could also indicate a dying 12V battery. Additionally, some owners have encountered a "beep-beep-beep" sound during the PRG operation, which may stem from an incomplete initialization procedure that can be resolved by manually opening the PRG with the ignition off. Excessive beeping complaints have also been noted when unlocking the car or opening and closing the trunk, causing annoyance during camping trips or nighttime activities. For tailgate malfunctions, troubleshooting steps such as checking for obvious problems, using the manual release, and disconnecting the battery may help reset the system. Furthermore, noise issues have been reported across various model years, with grinding noises in 2016 models and squeaking in 2018 models, particularly in damp weather. Addressing these concerns thoroughly is crucial for identifying and resolving the underlying problems.
