Hyundai Sonata NF

The 2004 Sonata NF leaned into the calm, almost classical character of a large family saloon. Hyundai's Korean specification records a 2.0-litre petrol engine, front-wheel drive and either a five-speed manual or four-speed automatic; a parts-catalogue record identifies this 2.0-litre version as G4KA.

The age of an NF calls for separating a vibration's source from engine mechanics rather than dramatizing every noise. With metallic sound or marked vibration, check oil pressure and assess the balance module before discussing repair scope.

A good NF earns its place through coherent behaviour: even start-up, a predictable automatic and no drifting symptoms on a long drive. It is a car best understood on an unhurried test route.
