Used Maruti Suzuki Swift in Pune

— The 2018-2021 Swift has a known susceptibility to rust formation on the underbody, particularly around the rear wheel arches and door edges. This is especially common in cars used in coastal cities (Mumbai, Chennai, Kochi) or areas with high humidity. Lift the car or use a mirror — if you see flaking rust on structural members (not surface rust on bolts), walk away. Repair costs can exceed ₹15,000 and the rust often returns.

— A common complaint on Swifts with 40,000-50,000 km. If you feel a shudder/vibration when releasing the clutch slowly in 1st gear (especially on inclines), the clutch disc is worn. The entire clutch assembly (plate + pressure plate + bearing) needs replacement. This is not a 'live with it' issue — it worsens and eventually the clutch will slip under load.

— If the MIL (check engine light) is on AND the engine idles roughly or misfires, it could indicate a failing catalytic converter (₹25,000+ repair) or faulty oxygen sensor (₹3,000-5,000). On diesel variants, this often points to injector problems (₹8,000-12,000 per injector). Get an OBD-II scan before purchase — any seller who refuses an OBD scan is hiding something.
