Frequently asked questions
Which Suzuki SX4 engine is the most reliable?
1.6 VVT (M16A) — Reliable verdict. The 1.6 M16A is the dependable, low-worry heart of the SX4 — a chain-driven Suzuki four that's simple, durable and cheap to run, with optional AWD a genuine plus over rivals. It earns 'reliable', with one model-year caveat: pre-2012 M16A engines can suffer exhaust cam-lobe wear (a top-end tick), which Suzuki cured with hardened cams from 2012. Otherwise just age items — oil consumption at high mileage, the odd chain-tensioner rattle, and a dislike of overheating. Modest on power, but one of the safer used small-crossover engines.
