- Most often, drivers complain about the vagaries of the ignition system, especially the distributor;
- In second place in popularity here are the failures of various electronic sensors;
- The timing belt runs approximately 50 – 60 thousand km, however, if it breaks, the valves will not bend;
- Due to the use of low-quality oils, hydraulic lifters can knock up to 100 thousand km.
