1. Continuously Variable Transmission (CVT) Problems

Problem: The CVT may overheat, causing jerky shifts, delayed acceleration, and premature failure.

Solution: Change the CVT fluid regularly, install an additional transmission cooler, and avoid aggressive driving.

2. Worn Engine Mounts

Problem: Worn or broken engine mounts can cause vibrations and knocking while driving.

Solution: Replace engine mounts at the first sign of vibration, especially when starting or stopping.

3. Suspension Problems (Sway Bars, Shock Absorbers)

Problem: Worn suspension components can cause poor handling, noise, and vibration.

Solution: Inspect the suspension regularly and replace the shock absorbers and struts as needed.

4. Steering Problems

Problem: Some models had problems with the steering racks, which manifested itself as knocking or play in the steering wheel.

Solution: Carry out regular checks of the steering rack and replace at the first sign of play or noise.

5. Air Conditioning Problems

Problem: Freon leaks and breakdowns of the air conditioning compressor were common complaints from owners.

Solution: Regularly check the freon level and the condition of the compressor, promptly eliminate leaks.

6. Electrical Problems

Problem: Some owners experienced failure of electronics, including window lifters, control units and sensors.

Solution: Monitor the condition of the electrical wiring, check fuses and control units for corrosion or damage.

7. Brake Disc and Pad Wear

Problem: The brake discs and pads on the B16 can wear out faster than usual, which reduces braking efficiency.

Solution: Check and replace brake discs and pads regularly, especially if there is noise or vibration when braking.

8. Exhaust system corrosion

Problem: The exhaust system can be subject to corrosion, especially in areas with severe winters or high humidity.

Solution: Check and clean the exhaust system regularly, especially in winter, to avoid corrosion and leaks.

9. Sensor errors (oxygen sensor, mass air flow sensor)

Problem: Faulty sensors can lead to reduced engine performance and increased fuel consumption.

Solution: Replace faulty sensors promptly and use a diagnostic scanner to identify errors.

Regular maintenance can help prevent many of these problems.

Monitor fluid levels and use only quality parts to extend the life of your vehicle.
