Why Does My Subaru Make Noise When off : Troubleshooting Strange Sounds

If you’re a Subaru owner, you may have experienced the frustration of hearing strange noises coming from your vehicle when it’s not even running.

Possible Reasons for the Noise

There could be several reasons why your Subaru is making noise when it’s not running. Below are some common issues that may be causing the sound:

1. Cooling System

The cooling system in your Subaru includes the radiator, cooling fans, and various hoses. After you turn off your car, the engine heat needs to dissipate, and this can cause the cooling fans to continue running for a short period. It’s normal to hear the fans running for a few minutes after you turn off the engine.

2. Fuel Pump

Another common source of noise in a parked Subaru can be the fuel pump. This mechanical component pressurizes the fuel system and could continue to make noise for a few minutes after the engine is turned off. It’s important to note that excessive or prolonged noise from the fuel pump could indicate a problem that requires professional attention.

3. Exhaust System

Even after your Subaru is turned off, the exhaust system can make ticking or clicking sounds as it cools down. This sound is usually normal and is caused by the metal components contracting as they cool.

4. Hydraulic Lifters

If you have an older Subaru model, the noise you hear could be caused by the hydraulic lifters. These components can be noisy, especially when the engine is still warm. In most cases, the noise should subside as the engine cools down further.

5. Electrical System

Electrical components, such as relays and switches, can cause clicking or buzzing sounds when the car is off. This can be due to residual energy in the system or normal operation of certain components. However, if you notice prolonged or loud electrical noises, it’s advisable to have the electrical system checked by a qualified mechanic.

When to Seek Professional Help

While some amount of noise from a parked Subaru is normal, it’s important to be attentive to any unusual or excessive sounds. If you notice any of the following symptoms, it’s recommended to seek professional help:

  • Prolonged or excessively loud noises
  • Clicking or tapping sounds that persist for an extended period
  • Unusual odors accompanying the noise
  • Any visual signs of leaking fluids or damaged components
