Disadvantages of the KR15DDT engine
The statistics of this turbo engine’s malfunctions have not yet been gathered; thus far, the only complaints on specialized forums have been about the Start-Stop system’s frequent malfunctions;
Because of the direct injection system, soot quickly overgrows the intake valves here;
The engine’s primary issue is where to fix the compression ratio system; there are no hydraulic lifters, and valve clearances must be changed every 100,000 kilometers.
