What years did Subaru have a bad engine?
Subaru has built a reputation for reliability and performance, but like any automaker, it has faced its share of challenges. Over the years, certain Subaru engines have been associated with recurring issues that have caused concern among car owners. In this article, we’ll explore the years and models that experienced engine problems, helping you make informed decisions about maintenance or purchasing a used Subaru.
Subaru's Engine Troubles: A Timeline
Subaru's engine issues primarily stemmed from two major problems: head gasket failures and oil consumption issues. These problems were more prevalent in specific years and models, which we’ll outline below.
Head Gasket Failures (Late 1990s to Early 2000s)
One of the most well-known issues with Subaru engines was the head gasket failure, which affected models equipped with the EJ25 engine. This problem was particularly common in the late 1990s and early 2000s. Here are the key details:
- Models Affected: Subaru Outback, Legacy, Impreza, and Forester.
- Years Affected: 1996 to 2004.
- Cause: The head gaskets in these engines were prone to leaking oil and coolant, leading to overheating and potential engine damage.
- Solution: Subaru later improved the gasket material and design, but many owners had to replace the head gaskets prematurely.
Oil Consumption Issues (2011 to 2015)
Another significant issue arose in more recent years, with excessive oil consumption affecting certain Subaru models. This problem was linked to the FB-series engines, which were introduced as part of Subaru's push for better fuel efficiency and lower emissions.
- Models Affected: Subaru Forester, Outback, Legacy, and Crosstrek.
- Years Affected: 2011 to 2015.
- Cause: The issue was attributed to piston rings that failed to seal properly, allowing oil to burn off excessively.
- Solution: Subaru addressed this problem through warranty repairs and updated engine designs in later models.
What to Do If You Own an Affected Subaru
If you own or are considering purchasing a Subaru from the affected years, here are some tips to ensure your vehicle remains reliable:
- Check Maintenance Records: Ensure that any necessary repairs, such as head gasket replacements or oil consumption fixes, have been completed.
- Monitor Oil Levels: Regularly check your oil levels, especially if you own a model from the 2011-2015 range.
- Consult a Professional: If you suspect engine issues, bring your vehicle to a trusted mechanic for a thorough inspection.

What year did Subaru stop using timing belts?
2011 was the first year for the newest version of the 2.5L normally aspirated engine. Years previous to 2011 the 2.5L, as did all Subaru flat four engines, used a timing belt. Beginning in 2011 the 2.5L uses a timing chain.
What causes Subaru engines to burn oil?
Reason #1: Bad Piston Rings
Over time, these piston rings can wear down. As they wear, they'll allow oil from the crankcase to seep past the pistons, where the oil will be burned by the engine. New piston rings can be costly, but it'll be a necessary procedure to keep the engine from burning oil.
