Disadvantages of the EE20Z engine
- The first years of production in these units, the crankshaft could not withstand the load and burst;
- At the end of 2010, an updated version of the motor appeared and the problem disappeared;
- Now the main headache is the frequent vagaries of the exhaust cleaning system;
- From bad fuel, injectors quickly fail here and the EGR valve clogs;
- If you do not replace the glow plugs in time, you will have to carefully drill them.
