Disadvantages of the Toyota 2AZ-FXE engine
Up until 2007, a coolant leak was caused by the cylinder head bolt threads breaking; motors released after that year typically experience a progressive oil burn; throttle fouling is the primary cause of floating rpm;
The chain stretches after 150,000 km, and the pump resource typically doesn’t go beyond 50,000 km. A recall was issued in 2010 because of a potential fuel leak in the event of an accident.
