About the 2019 Infiniti Q50
The 2019 Infiniti Q50 is a premium performance car. Our records list a 3498cc hybrid engine, though engines vary between versions. 45 MOT tests were recorded on this model in 2024, making it a rare model on UK roads. It ranks in the top 2% of all 2019 models for MOT pass rate.
With an average of 33,181 miles recorded at its 2024 MOT tests, Infiniti Q50 owners drive about as much as the UK average.
2019 Infiniti Q50 Fuel Costs
The 3498cc hybrid engine is on the larger side, so fuel won't be this car's strong point. Our estimate uses around 30 mpg, the figure for a petrol engine of this size, which works out to roughly £1,958 per year with petrol at 174.57p per litre (GOV.UK weekly average, week of 19 October 2026; based on 7,400 miles per year). As a hybrid it should use less than that, and real-world fuel costs depend a lot on how much electric-only driving you do.
What does it cost to own a 2019 Infiniti Q50?
Total estimated annual running cost is £2,413 (£201/month), broken down as £1,958 fuel, £200 road tax, £55 MOT, and £200 predicted repairs. The low repair estimate reflects the excellent 100% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.
Infiniti Q50 Reliability Trend
Newer Infiniti Q50s pass their MOT more often than older ones, by 4 percentage points on average, which is mostly down to age and wear.
Buying a Used 2019 Infiniti Q50
At 7 years old, this is a solid used buy if you find one with good service history. Depreciation has levelled off, so you won't lose much more value. Focus on condition over mileage. If you're flexible on year, the 2017 model has the highest pass rate at 88%. Note: with only 45 tests in our data, these figures should be treated as indicative rather than definitive.
Common Issues to Watch For
These are typical issues for cars of this age, fuel type and engine size, not faults recorded on this model's MOT tests. Use them as a checklist when you view one.
Hybrid Battery Health
Medium riskAfter 7 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.
Suspension Wear
Medium riskShock absorbers, springs, and anti-roll bar links typically need attention around this age. Listen for clunks over bumps and check for uneven tyre wear.
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.
