Disadvantages of the Suzuki K14C engine
This motor has been manufactured for over five years, and no unique issues have been reported to date;
Here, direct injection plays a role in the development of carbon deposits on the intake valves;
The turbine continues to operate normally, and instances of its sudden failure are still uncommon;
Concerns regarding timing chain stretching on runs of 100,000–150,000 km have been posted on specialized forums;
The aluminum engine cannot withstand overheating, so keep an eye on the cooling system’s condition.
