Które silniki Subaru należy unikać? Czy Subaru jest nadal niezawodny?

Subaru is a reputable Japanese car company, building consumers trust through its consistent quality cars.

However, in recent years, customers have often complained about the decrease in engine performance. Therefore, many Subaru seekers always consider which Subaru engines to avoid when purchasing.

We will point out major issues that appear in subpar engines.

Besides, we will provide a few more information about the Subaru boxer engine issues. Scrolling to the end, you may find some helpful things in the FAQ section.

Are Subaru Engines Reliable?

Which Subaru Engines To Avoid?

Major issues are still oil-related, including oil combusting, oil shortage, and head gasket failure.

Typically, these errors appear due to external agents after long usage. At Subaru, the inconsiderate engine engineering is the reason behind it.

As a result, the quality, performance, or endurance is not highly rated.

3. Subaru EJ205/EJ207/EJ20G Engine

We continue with the engine stuck with oil problems from Subaru. Unlike the two names above, engine oil leakage is a common error in EJ205/EJ207/EJ20G Engine, resulting from the clogged rings.

Subaru tried to comfort the users by its explanation about more premium oil and fuel quality. However, most of the customers consider it an excuse.

Poza tym klimatyzowany intercooler wydaje się trafiony, ponieważ nie może ostygnąć rdzenia silnika podczas pracy, szczególnie w zakresie wydajności o wysokim obciążeniu.

If the engine, unfortunately, experiences overheating, it will remain until fully damaged.

Subaru Engine Problems

Graphite-coated head gaskets have been found in vehicles with damaged engines. This shells adhesion is considered unstable, gradually fading after about 100,000 miles.

Discarding this adhesive means that the head gasket is more vulnerable.

Responding to the customers disappointment, Subaru has replaced the graphite head gasket with an uncoated multi-layer head gasket.

Oil leakage occurs most often in the 2.5-L engine EJ25D- a common built-in component of the Subaru Forester, Legacy, and Impreza line.

Oil and Coolant in the Chamber

The pistons are placed on the same plane, so their movements look like boxers. Thats how the engine has been named after.

Through the symmetrical horizontal structure, when the Boxer engine is operating, the two piston sequences will generate opposing forces, thereby canceling each other.

This operation offers a comfortable drive, a higher performance as well as durable longevity.

The problem lies in the engines motion which is not smooth and harmonious.

Besides, this engine is built with 2 heads. It requires two rows of cylinders, so the production cost will be much more expensive.

Subaru designed the Boxer Engine with a wide range. The structure expands horizontally but flattens in height (like a wide rectangular block).

This design triggers many difficulties in engine layout. The manufacturer had to build its own chassis with more complex calculations to install the Boxer engine.

Other drawbacks to mention are short rods and small bases, which have obstacles in withstanding heavy loads.

The rod pistons are also more likely to break down. In addition, the installation or repair of the engine is not easy and economical.

Why Do Subaru Engines Fail?

You can expect the engine to suddenly stop while the car is running, easily causing accidents on the highway.

Many drivers wonder why their check engine light becomes glowing.

That could be a sign of failure, and its time to replace the fuel pump . Ascent SUV, Impreza, or Legacy are still models with this condition.

Thats not the end of the story. Over 200,000 Subaru (Impreza and Subaru Crosstrek) models have their engines damaged due to the vehicles computer system.

The computer part was initially programmed with no finesse and precision.

Specifically, it does not stop supplying power to the ignition coil even when the motor is turned off.

Besides unnecessarily boiling the engine, it also induces electrical issues, such as fuse explosion, short circuit, or sudden engine power loss.

PCV valves are also the culprit of Subarus failed engines, namely cracks or separations. Split pieces of the PCV valve or oil can pass through that omission to enter the combustion chamber.

Not only causing excessive oil consumption, but the whole engine is also quickly degraded over time.

Operating with an PCV valve error, the cars engine is difficult to activate, vibrates, or shuts down. A jammed PCV valve can cause the Check Engine light to come on.

FAQ

The 2017 Subaru Forester is not recommended because of its weak engine coupled with electrical issues.

The battery system expresses poor life, which flickers when the car has not even reached 30,000 miles yet. The radio and navigation systems are also unreliable.

The manufacturings bugs throughout 2017-2019 does not exclude the Imprezas line.

Problemy są nie tylko związane z problemami elektrycznymi i programami komputerowymi, ale także komponentami silnika, takimi jak pęknięte zawór PCV lub pompa olejna.

Owners of these models often notice that the Check Engine signal lights up continuously for uncertain reasons.

Which Subaru Engine Has Head Gasket Problems?

The 2.5-L SOHC and EJ engines were disappointing because of a serious head gasket error.

Liczba pojazdów Subaru z nieprawidłowymi uszczelkami głowy rejestrowanymi w sklepach z naprawami samochodowej rośnie, dokładnie w liniach Forrester, Impreza i Legacy.

This error leads to oil and coolant leakage, overheated engines, and excessive oil consumption. Dealing with this complaint, Subaru decided to apply for warranty extensions at 100,000 miles.

What Are The Disadvantages Of A Subaru Boxer Engine?

Repairmen also need to spend more time and effort tackling any problem of a boxer engine.

Silnik bokserski jest ustrukturyzowany jako płaska cztery forma, z której głowice silnika, wałki rozrządu, uszczelki głowy, a nawet pasy rozrządu mają dwa razy więcej silnika prostego czterech.

The space to reach the engine head is relatively tight.

Ilekroć chcesz zmienić uszczelkę głowicy lub inne, silnik musi zostać wyjęty, co jest skomplikowane i czasochłonne i znacznie kosztuje.

What Are The Advantages Of A Subaru Boxer Engine?

We can not deny the benefits that the boxer engine contributes to your drive. Compared to conventional engines such as V-engine or I-engine, the boxer engine has the best balance.

The pistons are symmetrically designed to reduce vibration, helping the engine operate more smoothly.

Silnik bokserów jest umieszczony poziomo z płaską konstrukcją i niskim środkiem grawitacji, tworząc dobrą i schludną obsługę i zakręcie, niezależnie od warunków drogowych.

In addition, thanks to the CVT automatic transmission, the transmission is also more efficient.

Smooth acceleration is no longer out of your reach. Indeed, the boxer engine is extremely suitable for the driving enthusiast.

How Many Miles Will A Subaru Boxer Engine Last?

Liczba ta może wzrosnąć, jeśli inne komponenty (uszczelki głowy) stale działają.

W przeciwieństwie do innych części (małe, łatwe do demontażu itp.) Silnik bokserski jest trudny do utrzymania regularnie. W zamian jest również mniej prawdopodobne, że zostanie uszkodzony.

Wniosek

Mamy nadzieję, że zadowolimy cię naszą szczegółową odpowiedzią na obawy , których silniki Subaru należy unikać.

Podsumowując, Subaru nie może spełnić zadowolenia klienta w modelach Impreza, Legacy i Forrester w latach 2017-2019.

Marka wdrożyła również plany odszkodowań w celu zrównoważenia tego zaniedbania, takie jak przywołanie wadliwych pojazdów lub przedłużenie gwarancji.

Po okresie spadku jakości Subaru szybko poprawiło błędy w późniejszych produktach samochodowych.

Na szczęście modele 2020 i nowsze zostały ponownie dobrze ocenione i zaufane. Podsumowując, Subaru jest nadal warto rozważać opcję przy zakupie samochodu.
