What year does Subaru have a bad engine?
Subaru, the Japanese automaker known for its all-wheel-drive vehicles, has faced some engine-related challenges over the years. While the brand is generally praised for its reliability, there have been instances where certain Subaru models have experienced engine issues that have drawn the attention of both consumers and industry experts.
The Problematic Subaru Engines
One of the most notable engine-related problems that Subaru has faced was with the 2.4-liter turbocharged Boxer engine used in some of its models, including the Ascent, Outback, and Legacy. This engine was prone to excessive oil consumption, which could lead to engine failure if left unaddressed.
The oil consumption issue was particularly prevalent in Subaru models produced between 2011 and 2015. Owners reported having to add a quart of oil every 1,000 to 1,500 miles, which was well above the normal oil consumption rate. This problem led to a class-action lawsuit and a series of recalls by Subaru to address the issue.
Causes and Consequences
The excessive oil consumption in the 2.4-liter turbocharged Boxer engine was primarily attributed to design flaws in the piston rings and cylinder walls. These components were not adequately sealed, allowing oil to escape the engine and leading to rapid depletion of the oil supply.
The consequences of this issue were significant for Subaru owners. The need to constantly monitor and replenish the oil levels added an extra burden and expense, and in some cases, the engine failure caused by the oil consumption led to costly repairs or even the need to replace the entire engine.
Subaru's Response and Improvements
- Subaru acknowledged the problem and issued a series of recalls to address the oil consumption issue, including extending the warranty on the affected engines.
- The automaker also made design changes to the piston rings and cylinder walls in newer models to improve the sealing and reduce oil consumption.
- Subaru has since introduced new engine designs, such as the 2.4-liter turbocharged Boxer engine used in the latest Ascent, Outback, and Legacy models, which have not reported the same level of oil consumption problems.
While Subaru's engine troubles in the past have been a source of concern for some consumers, the company's efforts to address the issues and introduce more reliable engine designs have helped to restore confidence in the brand's reputation for quality and dependability.
