About the 2020 SUZUKI SWIFT SZ5 DUALJET MHEV
The 2020 SUZUKI SWIFT SZ5 DUALJET MHEV is a city car with a 1197cc hybrid engine. 106 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. Among all cars from 2020, the average MOT pass rate is 92%, and this model falls short of that benchmark.
With an average of 21,337 miles at 6 years old, SUZUKI SWIFT SZ5 DUALJET MHEV owners tend to use this car less than the typical driver. Very low mileage could mean the car has been garaged or used only for short trips, which can cause its own issues like battery drain and moisture buildup.
2020 SUZUKI SWIFT SZ5 DUALJET MHEV Fuel Costs
The modest 1197cc hybrid engine keeps fuel costs low, which is a real advantage for a city car. Expect around 50 mpg in mixed driving, which works out to roughly £955 per year at current hybrid prices of 142p per litre (based on 7,400 miles per year). As a hybrid, real-world fuel costs will vary significantly depending on how much electric-only driving you do.

Common Issues to Watch For
Based on the 2020 SUZUKI SWIFT SZ5 DUALJET MHEV's fuel type, age, and engine size, these are the most likely problem areas to check.
Hybrid Battery Health
Medium riskAfter 6 years, hybrid battery capacity may have reduced. A full replacement costs £2,000-£4,000, though reconditioning is cheaper at £500-£1,500.
Inverter and Power Electronics
Low riskThe inverter converts DC to AC for the electric motor. Failures are expensive (£1,500+) but relatively rare. Listen for unusual buzzing sounds.
Regenerative Braking
Medium riskBrake discs can corrode from reduced use (the electric motor handles most braking). Surface rust is normal but deep pitting needs attention.
Service History
Low riskAlways request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
