| Suaru imperza | The most dangerous problem of the engine is overheating. |
| Subaru legacy | Subaru used a casting process that impairs the powers of the piston. While the PCV system is causing vaporization of oil into the combustion chamber. |
| BRZ | Piston and PCV are consuming high powers which cause the engine to overheat and crash. |
Subaru Forester
- No doubt that the forester is one of the most popular models of Subaru. But the forester is also known to have had engine issues over the past years. Subaru Forester was reported many times for its excessive oil consumption.
- The major problem seen in the model was it is tiring off of stopping when it is overworked or crossed its stretched chain. The engine consumes about a liter or more of oil after traveling like 1500 km in its previous models. There were also complaints about its piston and piston rings. Also, they say that it has a high history of leaking fuel and diluting the oil.
-
So to figure out the actual problem they ran an oil consumption test. In the test, the engine would be considered defective if it consumes quarts (0.95L) of oil at 3000km of a distance. When they tested the engine, they realized that the liter of oil was lost in about 500 km of a distance.
-
There were cases on the company and then to satisfy the customer and fix the problem they made a rebuilt rit has more coating and there is an updated seal around the fuel pump.
Subaru Outback:
- Subaru Outback in the year 2013 was considered the worst model year for Subaru. There were complaints of frangible water pumps. The chain-driven engine was causing a lot of damage to the owners. The owner of the company has denied accepting the mistakes by saying that it is part of the normal working procedure.
- Models of 2013 and 2011 are known to have impaired pistons causing excessive oil consumption and engine failure.
Subaru Impreza
- The major and the most dangerous problem of the engine is overheating. The engine heats up to a dangerous amount and sometimes caught fire. The engine does not have a cooling agent that causes it to heat this much.
- Subaru Impreza just like outback and forester also have complaints about excessive oil consumption with short distance coverage.
Subaru legacy
- 2015 was the problematic year for Subaru’s legacy. Subaru used a casting process that impairs the powers of the piston. While the PCV system is causing vaporization of oil into the combustion chamber. So the vaporization causing oil to reduce and more workload on the piston which causing it to overheat and crashing ultimately.
Subaru BRZ
- This engine has an issue with engine replacement. The owners have to replace the engine and the replacement causing over $10,000.
- The case on them was that the piston and PCV are consuming high powers which cause the engine to overheat and crash.
Other Engines to avoid
Ford 1.6-L EcoBoost Four Cylinder
The major and the most dangerous problem of the engine is overheating. The engine heats up to a dangerous amount and sometimes caught fire. The engine does not have a cooling agent that causes it to heat this much.
There were almost 30 fire accidents were reported in the US due to overheating of the engine. There were reports of coolant leaking as well in the cylinder. Which is highly dangerous as well.
The company has to remake thousand of its models released in 2014. It is a big note to take when buying a car. Make sure to check the coolant and temperature of the vehicle.
Subaru 2.5-L Turbo Four Cylinder
-
This engine has an issue with engine replacement. The owners have to replace the engine and the replacement causing over $10,000.
