Kia 1.4 T-GDi
Compact turbocharged four-cylinder with good performance for the compact class. Keep oil changes consistent — turbo bearings are sensitive to oil degradation.
Turbo urban sprinter in a mini SUV
140 hp 1.4 T-GDi makes the compact Stonic a brisk city car. Surprisingly agile for a small SUV.
Engine Weaknesses 4
The G4LD 1.4 T-GDi in the Ceed/ProCeed shows known timing chain problems: chain stretch, tensioner skip and in severe cases engine damage. Early CD production years especially affected.
Symptoms: Fault code P0016 (crankshaft/camshaft position implausible), judder during acceleration, loud rattle on start-up
The G4LD 1.4 T-GDi is prone to timing chain elongation like its G4LC relatives, particularly with exceeded oil change intervals (recommended: max. 15,000 km). Over-stretching leads to engine damage.
Symptoms: Rattling from the timing chain area on cold start, engine warning light, camshaft sensor fault, rough running after cold start.
As a direct-injection engine the G4LD shares the fundamental GDi problem of all Kappa turbo engines: carbon deposits on intake valves. In the Ceed PHEV combination with the electric motor, the cleaning interval is particularly important.
Symptoms: Poor throttle response, rough idle, noticeable power reduction under partial load
As a direct-injection engine the G4LD does not clean the intake valves with fuel. Soot residues from crankcase ventilation build up on the valves and reduce gas flow.
Symptoms: Rough running in cold operation, power loss at low rpm, increased fuel consumption.
Vehicle Weaknesses 4
The Kia Stonic YB in several trim levels lacks adequate anti-pinch protection on the rear electric window regulators. There is an increased risk of injury to small children.
The ISG start-stop system on the Stonic YB frequently deactivates permanently when the starter battery is not fully charged. On short-trip drivers, the system is often inactive.
Base-spec Stonics are fitted with halogen headlamps that, according to buyers and testers, deliver only mediocre light output and receive MOT advisories for incorrect alignment.
According to user reviews, the Stonic YB has a relatively high noise level on the motorway. Wind and road noise intrude annoyingly into the interior, causing fatigue on longer journeys.
