The Outback is has a good reputation in the high mileage club. The Outback engine, if maintained and serviced timely, can easily cross the 200,000 miles mark.

1. Denso Fuel Pump Failure

The Subaru Outback uses a fuel pump from a company named Denso. In the Subaru Outback, some of their cars usually use two fuel pumps; a low-pressure fuel pump located in the tank, and a high-pressure pump attached to the fuel line.

The low-pressure pump has a rotating plastic disk inside it called the impeller. The impeller pushes fuel from the tank to the high-pressure pump. If the disk has a problem rotating, it would not be able to push the fuel forward. Unfortunately, the Denso fuel pump faces this problem.

The fuel pump manufactured by Denso usually fails because of an internal defect. Most of the cars manufactured by Subaru have these fuel pumps. The basic work of a fuel pump is to manage the flow of fuel from the tank to the engine. The problem is that Denso’s pumps use a low-density impeller. This causes the impeller to crack, absorb fuel, and break. This further deforms to the point that there is a problem with the flow of the fuel.

Due to an unreliable stream of fuel, the engine will slowly start running rough and becomes difficult to start. This might also cause the car to stall in the middle of the road.

2. Cracked Windshields Problems

Another one of the common Subaru Outback problems is that the windshield cracks spontaneously. Subaru introduced a new acoustic glass in 2015, which had several complaints of cracked windshields.

Usually, a normal windshield can crack due to pressure caused due to a pebble or a stone. Usually, at high speeds, it is a possibility that a stone or a pebble might hit your windshield at a high speed. This might cause the windshield to crack.

The main focus of these acoustic windshields was to dampen the road noise inside the car.  These windshields reduce the noise of the engine, the road, and outside driving noise. An acoustic windshield has more sound damping capabilities than a regular windshield.

A chipped windshield starts to crack from the point of impact and it slowly spreads over time. The acoustic windshield on the other hand starts developing cracks quickly that often start at the bottom where the windshield wipers are located (with a bit of help in how to change windshield wipers). There are several complaints regarding these windshields and there have been some recalls as well.

3. Subaru Starlink Problems

Subaru had introduced a new infotainment system called the Starlink infotainment system. They introduced this system in its 2016 models. One of the Subaru Outback problems was their Starlink system. It wasn’t a Subaru enthusiast’s favorite.

The outdated infotainment systems have always been a source of criticism for Subaru. In response to the criticism, they introduced the improved Starlink system in 2016. The Starlink system came with several new safety and connectivity features. Subaru introduced features like wireless Android Auto and Apple Play, collision avoidance, roadside assistance, etc.

The Starlink system was popular but short-lived. It uses a defective Harman Gen 3 audio system and navigation head units. Alongside that, it uses a buggy software that has a freezing problem making the infotainment system very difficult to use. The only way to get rid of this problem is to start the system all over again.

Here is a list of problems in the Starlink system.

  • The backup camera freezes or shuts down.
  •  The malfunctioning head unit causes the system to glitch. The main problem is that the audio and the radio controls get disabled.
  • The display might go blank or freeze.
  • A technical glitch causes the controls like the volume adjuster and the off button to stop working.

4. Unintended Acceleration

One of the more troubling of the 2011 Subaru Outback problems is the unintended acceleration. There have been several complaints that some of the Subaru models have unintended acceleration. This problem has been there in several Subaru cars and is most common in the 6th generation of the Outback.

There are a few plausible explanations for what might be causing this problem. The primary cause of these unintended acceleration problems in the Subaru is the increase in sensors available in all the new Subaru cars. This excessive new technology might be causing the car to behave in this way.

These multiple sensors and modules include things like the throttle position sensor and the throttle body assembly. If any of these sensors malfunction or have a defect they can be the root of this problem. The power control module might be a reason for causing the unintended acceleration problem.

Subaru has denied any problems with any of these sensors. They are holding a firm belief that it is the driver’s fault or a fault with the placement of the mats.

    I love my 2011 Outback but started pinging on regular gas & also occasionally all the dash lights come on . Garage computer says ignition fuel etc. any suggestions?

    • If the problem is occasional and isn’t affecting the drive. I would buy a cheapish code reader off Amazon and monitor the codes yourself.

      Write down when comes up and when and hopefully over time this will help narrow down what the issue is.
