Is the 1.2 and 1.4 TSI reliable?

It depends on the generation. The chain-driven 1.2 and 1.4 TSI EA111 engines (2006-2015) carry a recognised problem of chain stretch and tensioner failure, and the 1.4 twincharger engines from before 2012 can break pistons. The belt-driven EA211 engines (from 2012) are considerably more reliable: their typical fault is a leaking water pump.[1][2][3][4][5]

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.[6][7][8]
