Is the 1.0 and 1.4 Boosterjet reliable?

The Suzuki Boosterjet (1.0 K10C and 1.4 K14C/K14D) is a turbocharged direct-injection petrol engine with a timing chain, fitted since 2015 to the Vitara, S-Cross, Swift Sport and Baleno, with a 48 V mild-hybrid variant of the 1.4 since 2020. German TÜV inspection reports and the workshops we consulted rate its reliability as high: no widespread fault with the chain, oil, fuel pump or mild-hybrid system is documented.[1][2][3][4][5]

Is the 1.3, 1.5 and 1.6 gasolina (serie M) reliable?

Suzuki's M series (the 1.3-litre M13A, 1.5-litre M15A and 1.6-litre M16A, with a timing chain and indirect injection) has a reputation as a simple, reliable engine: we have found no documented serious fault in the block or the chain. What is on record are minor faults or one-off campaigns: the catalytic converter and lambda sensors of the 2005-2010 Swift, the catalytic converter of the 2006-2007 SX4, the Swift's fuel hose and the Grand Vitara and Jimny tensioner pulley.[6][7][8][9][10][11]
