Is the 2.4, 2.8 and 3.0 V6 30v reliable?

The 30-valve V6 engines of the Volkswagen Group (2.4, 2.8 and 3.0) have few documented faults: there are few owner reviews, and they mention coils, the thermostat and oil leaks. The most sensitive item is the timing belt, which on the 2.8 also drives the water pump: Audi and VW ask for it to be changed every 120,000 km, and the job takes 2.9 to 3.5 hours.^[1][2][3][4]

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.^[5][6][7]
