The most common reasons a 2009 Subaru Forester cruise control isn't working are failed control module, sensor or switch issues, or throttle actuation problems.

Sensor: A faulty sensor can lead to incorrect readings, causing issues with engine performance or triggering warning lights on the dashboard.
Control Module: A faulty control module can result in erratic vehicle behavior or failure of various electronic systems due to improper signal processing.
Throttle: A faulty throttle body or a defective accelerator pedal position sensor may be causing inconsistent acceleration and poor engine response.

How urgent is it to address the non-functioning cruise control in a 2009 Subaru Forester?

Addressing the non-functioning cruise control in your 2009 Subaru Forester should not be overlooked, as it can lead to a range of complications that may affect your vehicle's overall performance. While the immediate safety risk may seem minimal, a malfunctioning cruise control system can indicate deeper issues with critical components such as the control module, sensors, or throttle actuation. Ignoring these symptoms could result in more significant problems down the line, potentially impacting your vehicle's acceleration and speedometer functionality. Moreover, the convenience of cruise control, especially during long drives, cannot be understated; it helps reduce driver fatigue and enhances comfort. Therefore, it is advisable to address this issue promptly to ensure your vehicle operates optimally and to prevent any further complications that could arise from neglecting the problem.

Subaru Forester rear hatch door malfunction, unable to open repeatedly

Some Subaru Forester owners report experiencing issues with the rear hatch door malfunctioning, such as the hatch refusing to open despite attempts with the key fob or dash button, necessitating the use of an emergency release. Additionally, some users find that the hatch may only unlatch partially or open a crack without fully releasing. Reports also indicate that the rear hatch can get stuck closed, accompanied by beeping sounds when trying to open it. While resetting the hatch may provide a temporary fix, many owners note that the problem often returns after a few uses. To mitigate these issues, some owners recommend checking the battery in the remote control and using the manual release button inside the hatch as a temporary solution if the hatch remains unresponsive.
