How To Fix A Malfunctioning Subaru “Push Start” Switch

A malfunctioning “Push Start” switch in your Subaru can be a frustrating experience, especially if you’re in a hurry.

Understanding the reasons behind this issue and how to address them can save you from unnecessary stress and delays. This article will guide you through the common causes of a malfunctioning “Push Start” switch and provide step-by-step instructions on how to fix it.

Common Causes of Push Start Malfunctions

1. Dead Key Fob Battery
One of the most common reasons for a malfunctioning push start switch is a dead or weak key fob battery. The key fob communicates wirelessly with the car’s ignition system, and if the battery is low, the signal may not be strong enough to engage the engine start.

  • Signs of a Dead Key Fob Battery: If your Subaru’s push start button is unresponsive, but the lights on your key fob are dim or not flashing at all, it’s likely the battery is dead.
  • Solution: Replace the key fob battery with a new one. Most key fobs use a standard coin-cell battery, which is easily available at stores. Make sure to replace the battery as per the instructions in your Subaru’s owner’s manual.

2. Faulty Brake Pedal Switch
The push start system requires you to press the brake pedal before the engine starts. If the brake pedal switch is faulty, the car won’t recognize that the pedal is pressed, preventing the engine from starting.

  • How to Identify: If pressing the brake pedal doesn’t engage the brake lights, or if the push start button doesn’t respond when pressed, the brake pedal switch could be the issue.
  • Solution: Check if the brake lights come on when the pedal is pressed. If they don’t, the switch may need to be replaced. This is a relatively simple fix that a professional can handle quickly.

3. Damaged Push Start Button
Physical damage or wear and tear on the push start button itself can also cause malfunctions. If the button is loose, sticky, or unresponsive, it may be due to internal damage.

  • Indications of Damage: The button might feel different when pressed, or there could be no response when attempting to start the car.
  • Solution: Inspect the push start button for any visible damage or wear. If the button is damaged, it will need to be replaced by a professional.

4. Electrical Issues
Electrical problems within the car’s ignition system can also prevent the push start button from working correctly. Faulty wiring, blown fuses, or other electrical issues could disrupt the connection between the push start switch and the car’s ignition system.

  • Signs of Electrical Issues: Dim dashboard lights, flickering lights, or no lights at all when pressing the push start button might indicate electrical issues.
  • Solution: Check the fuses related to the ignition system in the fuse box. If you find a blown fuse, replace it with one of the same amperage. For more complex electrical problems, it’s best to consult a professional technician.
