Technical characteristics of SouEast S09: what's under the hood?

Under the hood S09 hiding 1.5 liter turbocharged engine 150 hp, combined with a 6-speed automatic transmission Aisin. This transmission is considered one of the most reliable in its class, which distinguishes the model from many Chinese competitors with crude gearboxes. However, there are nuances:

  • 🔧 Engine: Unit 4G15T (Mitsubishi license) is known for its survivability, but demanding on oil quality. Owners note that when using cheap lubricants, increased oil consumption appears after 30–40 thousand km.
  • ⚡ Turbine: The resource of the turbocharger is a weak point. When driving aggressively, the first signs of wear (extraneous noise, loss of power) may appear as early as 60–80 thousand km.
  • 🔄 Gearbox: Aisin TF-60SN reliable, but afraid of overheating. In traffic jams it is recommended to turn on the mode Sport to reduce the load on the torque converter.

According to the passport data, fuel consumption in the combined cycle is 6.5–7.2 l/100 km. However, real reviews from owners speak volumes 8–10 l/100 km in the city and 6–7 l/100 km on the highway. The difference is explained adaptation to Russian fuel (especially noticeable when refueling with 92-octane gasoline).

  3. Chassis. Suspension type MacPherson front and multi-lever the rear provides comfort on uneven surfaces, comparable to European sedans.
  4. Warranty. Official guarantee - 5 years or 150 thousand km, which is above the market average.

The main fear of buyers SouEast S09 — unpredictable reliability. Despite the use of licensed units (engine from Mitsubishi, box from Aisin), assembly and components leave questions. Here are the most common complaints:

Crankshaft oil seal leak Oil stains under the car, burnt oil smell 15–25 thousand rubles. After 40–60 thousand km
Oxygen sensor failure Check Engine, increased fuel consumption 8–15 thousand rubles. After 30–50 thousand km
Interior plastic creaks Extraneous sounds when driving over uneven surfaces Free (guarantee) or 3–5 thousand rubles. From the first months of operation
Threshold corrosion Rust on welds, blistering paint 30–70 thousand rubles. (depending on degree) After 2–3 years in regions with salt on the roads

Owners cite this as a particularly critical problem. electronics. Multimedia system SouEast Connect often “glitchy”: it reboots spontaneously, loses connection with the phone, or refuses to recognize voice commands. Software updates are rare, and dealers are not always able to help.

Comparison with competitors: which is better - S09, Chery Arrizo 5 or Geely Emgrand?

In the price segment up to 1.5 million rubles from SouEast S09 there are direct competitors: Chery Arrizo 5, Geely Emgrand and Haval Jolion (crossover, but often seen as an alternative). Let's compare the key parameters:

  • 💰 Price: S09 cheaper Geely 50–100 thousand rubles, but more expensive Chery by 30–50 thousand
  • 🔧 Reliability: According to reviews, Geely Leads in build quality SouEast - in second place, Chery lagging behind due to problems with boxes.
  • 🚗 Comfort: S09 wins in terms of interior space, but loses Geely in sound insulation.
  • 🔌 Electronics: U Geely and Haval multimedia is more stable than SouEast.

If the priority is reliability, better take a closer look Geely Emgrand. If needed spacious interior at a minimal price, S09 becomes an interesting option. But Chery Arrizo 5 worth considering only if you're on a limited budget - her box DCT often fails after 50 thousand km.

Detailed comparison of S09 and Geely Emgrand engines

SouEast S09 is equipped with a 1.5T (150 hp) from Mitsubishi, while Geely Emgrand offers 1.4T (140 hp) of its own design. Despite the lower power, the Geely engine is considered more durable thanks to the aluminum cylinder block and timing chain drive (the S09 has a belt that requires replacement every 60 thousand km). However, the turbine on Geely also does not last forever - its resource rarely exceeds 120 thousand km.

Maintenance and repair: how much does it cost to maintain an S09?

One of the key questions when purchasing SouEast S09 — cost of ownership. Compared to Korean sedans (Kia Rio, Hyundai Solaris) maintenance is cheaper, but there are pitfalls:

  • 🛢️ Oil change: Every 10 thousand km (synthetic 5W-30 or 5W-40). Cost - 3–5 thousand rubles. with work.
  • 🔧 TO-1 (15 thousand km): Oil change, filters, diagnostics - 8–12 thousand rubles.
  • 🔄 Replacing the timing belt: Every 60 thousand km — 15–20 thousand rubles. (with rollers).
  • 🚨 Warranty repair: Dealers often refuse to recognize electronics problems as “warranty issues,” citing “misuse.”

The most painful expense item is spare parts. Despite the use of licensed units, many parts (for example, ABS sensors or suspension elements) you have to order from China with a wait of up to 1–2 months. Prices for original spare parts are 20–30% higher than those of the Koreans.

⚠️ Attention! Upon purchase SouEast S09 check with your dealer for availability spare parts warehouse in your region. In some cities (for example, Siberia), owners have to wait 3-4 weeks for parts, which makes the car impractical for daily use.

Reviews from real owners: honest stories

To form an objective opinion about SouEast S09, we analyzed reviews on the forums (Drive2, Drom.ru) and on social networks. Here are some typical stories:

Andrey, Moscow, mileage 25 thousand km:

"I bought a new one S09 in 2023. I was delighted for the first 10 thousand km - the car is comfortable, dynamic, the interior is spacious. But then problems began: first the parking sensors failed, then the multimedia began to fail. The dealer refused to recognize this as a warranty issue, citing the fact that I “used it incorrectly.” As a result, I spent 20 thousand on diagnostics and repairs from a third-party technician.”

Olga, Yekaterinburg, mileage 40 thousand km:

“I took S09 like the first car. During the year of operation there were no serious breakdowns, but little things are annoying: creaking plastic, stiff windows, sometimes the central locking does not work. Consumption in the city is 9.5 l/100 km, which is a bit much for a 1.5T. Otherwise, the machine earns its money.”

Igor, Krasnodar, mileage 60 thousand km:

“I bought it used S09 2022. The previous owner did not take care of the oil - as a result, the turbine began to “whistle” at 55 thousand km. The repair cost 60 thousand rubles. Now the car drives normally, but I only trust it for short distances. For long trips I take another car.”

General trend: owners praise S09 for comfort and design, but they scold for minor improvements and problems with service. Many people note that the car requires careful attention — missed maintenance or savings on spare parts result in expensive repairs.

💡

SouEast S09 is suitable for those who are willing to put up with minor shortcomings for the sake of a low price and a spacious interior. If you need a “set it and forget it” machine, it is better to consider Korean or European alternatives.
