Frequently asked questions
Which Honda Accord engine is the most reliable?
2.0 i-VTEC (K20) — Reliable verdict. The K20 petrol — a dependable, chain-driven Honda workhorse and the low-stress choice for short-trip drivers (no DPF to worry about). It genuinely earns 'reliable', with two honest Honda quirks: the VTC actuator (variable cam timing) commonly grinds/rattles for a second or two on a cold start as its locking-pin spring wears — Honda calls it harmless, but left for years it can stress and stretch the timing chain, so it's worth fixing; and like all Honda i-VTEC engines the valves are screw-adjustable and need periodic clearance checks or they tighten and eventually burn. Sluggish and needs revving, but mechanically very sound.
