About the Forester
The Forester first made its debut back in 1997. Since then, a total of five generations have been unveiled. The latest of these hit the markets in 2018.
The model, like a number of Subaru offerings, has seen intermittent praise over the years. Some of the most notable of its accolades include the 2009 and 2014 Motor Trend SUV of the Year.
The compact crossover SUV has faced a number of competitors over the years, mainly from other Japanese manufacturers. The most notable of these include the Honda CR-V, Mazda CX-30, and Volkswagen Tiguan.
The most common issue that the model has faced over the years is fault code P0420. This code indicates that there is a problem with the catalytic converter.
There are a number of things that should be done when addressing this issue. The oxygen sensors near the catalytic converter should be checked for any issues and the exhaust should also be checked for leaks, particularly upstream of the converter. In some cases, the converter needs to be replaced.
Another common code is P0700, which relates to the transmission control system. This is a ambiguous code that typically needs a higher-quality code scanner to pick up the cause of the issue.
This code may commonly pop up after changing automatic transmission fluid, which can be a clear indicator that there is a problem with the fluid.
Fault code P0028 is another code that the Forester has faced fairly often. This code is logged when a problem has been detected with the intake valve control solenoid for the second bank of the engine.
One of the most common causes that owners have reported is dirty or old engine oil. The addition of engine cleaners has proved to be fairly successful in many cases.
