Suzuki Swift 6-FL

Mild hybrid variant of the K12C with a 12V integrated starter-generator (ISG) and lithium-ion buffer battery. Two recalls (charging control software + V-ribbed belt) affected early 2016–2017 model years; largely resolved from the 2018 model year onwards.

• !! Recall: ISG Battery Charge Control (97CM)

  A software fault in the engine control unit prevents the 12 V Li-ion buffer battery from charging correctly. In extreme cases the engine shuts off while driving and cannot be restarted. Suzuki carries out a software update.

  Symptoms: Flashing 'Eng-A-Stop OFF' symbol, sudden engine shutdown while driving, unable to restart

• !! Recall: ISG/Water Pump Serpentine Belt (97CL)

  The serpentine belt driving the integrated starter-generator and water pump can snap. Consequence: alternator failure and overheating risk due to loss of coolant circulation. Suzuki replaces the belt free of charge under the recall.

  Symptoms: Charging system and/or coolant temperature warning light on, squealing from engine bay, hybrid system power loss

• ! ISG Malfunction After Cold Start

  The integrated starter-generator can remain permanently disabled after detecting brief belt slip, even after correct warm-up. An ECM update resolves the issue on affected vehicles.

  Symptoms: Hybrid functions remain inactive, energy flow display shows abnormal status, no boost on acceleration despite full buffer battery

  Ad Suzuki SHVS ISG ECM update

1.4-litre turbo four-cylinder with 48V SHVS mild hybrid — the integrated starter-generator noticeably fills the turbo lag earlier than in the non-hybrid. 235 Nm torque, more responsive throttle despite 11 PS less than the K14C. Early reports show occasional starting issues; mechanically the engine is considered solid. Long-term data still limited.

• !! Timing chain premature stretch from 80,000 km

  Timing chain starts rattling from 15,000–25,000 km, at 80,000–100,000 km total failure with engine damage possible. Inspect chain tensioner every 30,000 km.

  Symptoms: Cold start rattle, metallic noises, power loss

• !! Fuel injector failure from 60,000 km

  Injectors develop faults from 60,000 km — rough running and increased consumption. Affects all 1.4 Boosterjet variants.

  Symptoms: Rough engine running, increased fuel consumption, check engine light

• !! Turbocharger bearing wear from 130,000 km

  Turbo bearings develop play from 120,000–150,000 km — whistling under load, power loss. Regular oil changes are the best prevention.

  Symptoms: Whistling noise under load, power loss, blue smoke
