Engine Performance:

Some owners have reported occasional issues with carbon buildup in the intake valves, particularly with the 2.0L engine, leading to a slight loss of power or rough idle. Regular fuel system cleaning can help mitigate this.

Transmission:

The 4-speed automatic transmission, while generally reliable, can sometimes exhibit delayed shifts or a slight harshness. Fluid changes according to the maintenance schedule are crucial.

Electrical:

Infrequent reports of minor electrical glitches, such as issues with power windows or infotainment system responsiveness, can occur. Software updates or battery terminal checks often resolve these.

Suspension And Steering:

Wear on suspension components like tie rod ends and bushings can occur over time, leading to steering looseness or knocking noises. Regular inspections are recommended.

Brake Wear:

Normal wear and tear on brake pads and rotors is expected. Some models might exhibit premature rotor warping if subjected to heavy braking or extreme conditions.
