Suzuki Swift
Reliable 1.2-litre naturally aspirated engine with port injection and a maintenance-free timing chain. No systemic engine problems known; the drivetrain is considered robust. The main risk at purchase is age-related oil seepage at the cam cover and crankcase.
Efficient and light, but tame
The Dualjet engine runs smoothly and economically, and the modern Swift VI is nimble and manageable. If power matters, go for the Boosterjet.
Engine Weaknesses 2
Slight oil seepage at the valve cover gasket at higher mileage. Not a safety-critical issue, but oil level must be checked regularly to prevent engine damage.
Symptoms: Oil smell in engine bay, visible discolouration at the valve cover, slight oil traces on the engine block
The start-stop system can remain permanently disabled with a weak starter battery or after frequent short trips. A battery replacement usually suffices; occasionally a control unit adaptation is needed.
Symptoms: 'Eng-A-Stop OFF' warning light on permanently, automatic engine stop no longer functioning
Vehicle Weaknesses 6
The vacuum pump check valve can swell due to fuel and oil additives, temporarily disabling the brake servo. Drivers need to apply significantly more pedal effort.
From model year 2019, no factory wax coating is applied to the underbody. Rust appears on suspension parts, weld seams and cavities, especially after exposure to road salt.
On vehicles produced between October and December 2015, the locking coating on the rear axle bolts may be missing. The bolts can gradually work loose, negatively affecting handling.
Worn front axle suspension components manifest as loud clicking noises when cornering or going over bumps. Affects wishbone bearings and anti-roll bar drop links.
Individual vehicles show sporadic electrical faults: wipers operate extremely slowly or fail to return to the rest position. Central locking occasionally does not engage.
The A/C compressor can fail at higher mileages or after prolonged non-use. Refrigerant loss through leaking connections is a common secondary issue.
