1. Engine and turbocharging

EJ25 (naturally aspirated and turbocharged) – overheating problem due to a blown cylinder head gasket. It is important to change the antifreeze on time and monitor the temperature.

Turbocharged versions (EJ255, EJ20T) – prone to high oil consumption, and when overheated, they can cause scoring in the cylinders.

EE20 diesel – problems with the fuel injection pump and diesel particulate filter at high mileage.

2. Transmission

Automatic (4EAT, 5EAT) – reliable, but requires regular oil changes. Overheating is possible with aggressive driving.

5-speed manual transmission – worn-out cars have problems with synchronizers.

CVT – not the best, does not like sharp acceleration and requires high-quality oil.

3. Suspension

Stabilizer struts and bushings wear out quickly, knocking sounds appear.

Rear silent blocks of levers require replacement after 100-150 thousand km.

4. Electrics

The lambda probe and mass air flow sensor (MAF) often fail.

Central lock and window lifters - wiring break in the doors.

The heater fan brushes can wear out, causing the heater to stop working.
