About the 2013 INFINITI M
The 2013 INFINITI M is a premium performance with a 3498cc hybrid engine. 68 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. Among all cars from 2013, the average MOT pass rate is 80%, and this model beats that benchmark.
With an average of 85,523 miles at 13 years old, INFINITI M owners drive about as much as the UK average.
2013 INFINITI M Fuel Costs

Expect around 30 mpg in mixed driving, which works out to roughly £1,592 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.

Buying a Used 2013 INFINITI M
At 13 years old, the INFINITI M is firmly in budget territory. Purchase prices are low, but check for rust, worn suspension bushes, and electrical gremlins. A full service history is especially valuable at this age. If you're flexible on year, the 2014 model has the highest pass rate at 92%. Note: with only 68 tests in our data, these figures should be treated as indicative rather than definitive.
Common Issues to Watch For
Based on the 2013 INFINITI M's fuel type, age, and engine size, these are the most likely problem areas to check.
Hybrid Battery Health
Watch outAfter 13 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
Medium 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.
Rust and Corrosion
Watch outAt 10+ years, check wheel arches, sills, subframe, and brake lines for rust. Structural corrosion is an MOT failure. Prevention is far cheaper than repair.
Suspension Bushings
Watch outRubber suspension bushes harden and crack with age, causing knocking noises and vague handling. A full refresh costs £300-£800 depending on the car.
Clutch Wear
Medium riskWith an average of 86k miles, clutch replacement may be due (typical lifespan 60,000-100,000 miles). Budget £400-£800 for a new clutch kit.
Brake Discs and Pads
Medium riskHigh-mileage cars often need brake disc replacement, not just pads. A full set of discs and pads costs £200-£500 per axle.
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.
