Is the 1.5 K15B (Jimny) reliable?

The 1.5 K15B in the Suzuki Jimny is a 102 hp naturally aspirated four-cylinder with a timing chain, simple and with no documented faults of its own. The only thing recorded in Europe is a 2018-2020 recall for the fuel pump, precautionary and with a definitive remedy.^[1][2][3]

Is the VR6 reliable?

Its best-documented faults are the timing chain, with tensioners on the 12-valve versions and stretching on the 3.2 (R32, A3 8P, TT, Cayenne), and, to a lesser extent, the cooling system of the 12-valve versions. The 3.6 FSI comes out of the sources better than the 3.2.^[4][5][6]
