Disadvantages of the C18NZ engine

- Most often, failures occur in the ignition system or some sensors are buggy;
- The timing belt does not have a very large resource, but when it breaks, the valves do not bend;
- If you use low-quality oil, then closer to 100,000 km, hydraulic lifters will knock.
