Disadvantages of the A25A-FXS engine
It has high requirements for gasoline quality, just like all units with D-4S injection;
Leaks in the EGR liquid cooler are known to occur in all Dynamic Force series engines;
Antifreeze may enter the combustion chambers if this heat exchanger cracks. The EGR system gets clogged with deposits and eventually wedges closer to 100,000 kilometers.
