2015 Mazda CX-5 2.2L Diesel · LR15 FJF

The Mazda CX-5 2.2 diesel typically returns 45-55 mpg in real-world driving, depending on journey type, giving excellent range from the 58-litre tank. Road tax for this 2015 model falls in a moderate band, though as the vehicle is now over 11 years old the standard rate applies. Insurance for the CX-5 diesel typically sits in groups 18-22, meaning premiums of £400-£700 per year for an average UK driver.

Maintenance costs are generally reasonable for the CX-5, with parts availability good through Mazda dealers and independent specialists. The 2.2 diesel requires quality engine oil and regular fuel filter changes. Brake work tends to be the main recurring cost, and as this vehicle has shown, discs may need replacing every 40,000-60,000 miles depending on driving style. The estimated annual running cost combining fuel, tax, insurance, and routine maintenance for this vehicle is in the region of £1,800-£2,200.

Begin with a thorough visual inspection of all four tyres, paying particular attention to inner-edge wear patterns as flagged in the 2024, 2025, and 2026 MOT tests. Uneven inner-edge wear on a CX-5 can suggest camber issues, worn suspension bushes, or simply a car that has been driven hard on motorways. Measure tread depth across the full width of each tyre and check for any sidewall damage or perishing, particularly on the offside rear which has been flagged for cracking.

Inspect all brake discs for lipping, scoring, and corrosion. The front and rear discs have been flagged at consecutive MOTs, so measure disc thickness against manufacturer minimums if possible. Check the track rod end dust covers on both sides, which have shown cracking in 2025 and 2026, and have the steering components checked for play. Lift the vehicle if possible to examine the offside front suspension arm bush and rear brake components.

Finally, check under the bonnet for any signs of the oil leak flagged in 2026. Look for fresh oil residue on the engine block, turbo area, and oil filter housing. Start the engine from cold and listen for any unusual diesel clatter or timing chain noise. Check the exhaust system for blue smoke (indicating oil burn) or excessive black smoke (indicating fuel system issues). On the test drive, ensure the automatic or manual gearbox (depending on variant) shifts smoothly and there are no warning lights on the dashboard.
