Disadvantages of the Z12XE engine
- The main problems of the motor are associated with electrical glitches, usually the ECU unit fails;
- The timing chain rarely goes more than 100 thousand km, and then stretches and starts to rattle;
- Quite often, the EGR valve is clogged with soot and the exhaust manifold is cracking;
- The thermostat, as well as the oil pump, do not have the greatest resource here;
- The use of low-quality oils quickly affects the condition of hydraulic lifters.
