The 1.8-liter Suzuki M18A engine was assembled at the company’s plant in Japan from 2001 to 2007 and installed on Aerio for the Asian and Australian markets, and then it was produced in China for a couple of years. Such a power unit is quite often used for swap instead of the M13A or M16A motor.
Engines of the M-series: M13A, M15A, M16A, M18A.

Disadvantages of the Suzuki M18A engine
- Most often, car owners with such an engine complain about high lubricant consumption.
- The motor overheats quite quickly and at the same time often breaks through the cylinder head gasket.
- The reason for floating engine speeds is usually a dirty throttle or EGR valve.
- Other weaknesses of the unit include short-lived supports and problematic sensors.
- At high mileage, liners can sag and antifreeze will mix with oil.
