Reasons for a Denso Fuel Pump Failure in a Subaru From Experienced Mechanics in Marlborough

August 20, 2022

Learning that a part of your car has been recalled is a cause for concern for almost any car owner. Recently, Subaru has recalled many of its 2018 , 2019 , and 2020 models for possible Denso brand fuel pump failure . Denso is a manufacturer of fuel pumps and modules in some Subaru models.

We will explain all you need to know about this recall, including whether your vehicle is affected, how to tell if you’re having fuel pump problems , and where to go for help.

Models Affected by the Denso Fuel Pump Recall

Subaru has recalled nearly 200,000 vehicles because of a Denso-brand fuel pump failure . These vehicles include:

  • 2019-2020 Subaru Ascent
  • 2018 Subaru Forester
  • 2018-2020 Subaru Impreza
  • 2018-2020 Subaru Legacy
  • 2018-2020 Subaru Outback
  • 2018-2019 Subaru BRZ
  • 2018-2019 Subaru WRX

If you own any of these models, you should go to your nearest automotive repair shop to get the problem fixed, especially if you are experiencing fuel pump issues .

Symptoms of Denso Fuel Pump Failure in Subaru

If your vehicle has been affected by the recall, it’s a good idea to take it in for repair even if you’re not experiencing problems at the moment. If you are experiencing problems, however, then you should definitely take your car in for a check-up.

Unfortunately, it can be difficult to tell exactly what the problem is based on symptoms alone. Because the systems inside your vehicle are so interconnected, many different problems can cause the same symptoms. However, it can still be helpful for the mechanic if you’re able to articulate what’s going wrong so they can narrow it down faster.

With that being said, here are some of the most common symptoms of fuel pump failure:

  • Stalling: When the fuel pump is failing, it means that there is either too much or too little fuel being fed into the combustion chamber . When this happens, your car is far more likely to stall out . Many Subaru owners have reported their cars stalling at both high and low speeds, and in some cases, they found themselves unable to get the car to restart . Particularly in busy highway situations, this can be incredibly dangerous and put drivers at risk of an accident .
  • Engine running rough: Before stalling happens, you might notice your Subaru is running rough . What this means, essentially, is that the car is shaking while idling or making strange noises like knocking sounds .
  • Reduced fuel economy: As with most things that go wrong in a vehicle, a faulty or failing fuel pump will likely lead to lowered fuel economy , because the fuel pump is responsible for regulating how much fuel is in the engine at any given time. The engine requires a careful balance of fuel and air, and if that balance is not maintained, it can’t run at its highest level of efficiency. You’ll probably end up having to go to the gas station more often than before.
