Kami akan menunjukkan masalah besar yang muncul di mesin di bawah standar.

Selain itu, kami akan memberikan beberapa informasi lebih lanjut tentang masalah mesin Subaru Boxer. Gulir ke akhir, Anda mungkin menemukan beberapa hal bermanfaat di bagian FAQ.

Apakah mesin Subaru dapat diandalkan?

Subaru bukan pengecualian. Jadi, terlepas dari daftar di bawah ini, Subaru masih merupakan merek mobil yang dapat Anda pertimbangkan.

Mesin Subaru mana yang harus dihindari?

2. Subaru EJ25

The Subaru EJ25 is commonly installed in Subaru Forester and Legacy lines, and it has the most errors. The engine includes two forms: a naturally aspirated 2.5-liter boxer engine and a twin camshaft.

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

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.

The problems are not only related to electrical issues and computer programs but also engine components like cracked valve PCV or cracked oil pump.

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.

The number of Subaru vehicles with malfunctioning head gaskets recorded at auto repair shops is increasing, exactly in the Forrester, Impreza, and Legacy lines.

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.

The boxer engine is structured as a flat-four form, of which engine heads, camshafts, head gaskets, and even timing belts are twice that of a straight-four engine.

The space to reach the engine head is relatively tight.

Whenever you want to change the head gasket or others, the engine must be taken out, which is complicated and time-consuming and costs you significantly.

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.

The boxer engine is placed horizontally with a flat design and low center of gravity, creating good and neat handling and cornering regardless of road conditions.

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?

dapat menyajikan hingga 300.000 mil .

Jumlah ini dapat meningkat jika komponen lain (gasket kepala) beroperasi dengan mantap.

Tidak seperti bagian lain (kecil, mudah dibongkar, dll.), Mesin Boxer sulit dipelihara secara teratur. Sebagai imbalannya, juga cenderung rusak.

Kesimpulan

Kami berharap telah memuaskan Anda dengan jawaban terperinci kami atas kekhawatiran yang harus dihindari oleh mesin Subaru.

Singkatnya, Subaru tidak dapat memenuhi kepuasan pelanggan di model Impreza, Legacy, dan Forrester selama 2017-2019.

Merek ini juga telah menerapkan rencana kompensasi untuk mengimbangi kelalaian itu, seperti mengingat kembali kendaraan yang rusak atau perpanjangan garansi.

Setelah periode penurunan kualitas, Subaru juga dengan cepat meningkatkan kesalahan dalam produk mobil selanjutnya.

Untungnya, model 2020 dan kemudian telah dievaluasi dengan baik dan dipercaya lagi. Secara keseluruhan, Subaru masih merupakan opsi yang layak dipahami saat membeli mobil.
