TL;DR

The Mazda CX-5 is a reliable SUV, but potential buyers should inspect for common issues like diesel particulate filter blockages and electrical faults. A thorough check of the service history, bodywork, and test drive performance is essential before purchasing a used model.

Paperwork

Start by checking the V5C document. Ensure the name on the document matches the seller’s ID. Review the service history for regular maintenance records. A complete service history indicates the car has been well cared for.

Bodywork

Inspect the bodywork for scratches, dents, or rust. Pay special attention to the wheel arches and sills, as these areas are prone to corrosion. Check panel alignment to spot any previous accidents or repairs.

Engine Cold-Start

When you start the engine, do it from cold. Listen for any unusual noises like knocking or tapping. Look for excessive smoke from the exhaust, which could indicate engine problems. Ensure the engine runs smoothly without any warning lights on the dashboard.

Test Drive Checklist

During the test drive, focus on the steering response and braking performance. The CX-5 should handle well without any vibrations. Test the acceleration and listen for any strange noises from the gearbox. Ensure all gears engage smoothly.

Gearbox

Both manual and automatic gearboxes should operate without issues. For automatics, check for smooth transitions between gears. In manuals, ensure the clutch engages properly without slipping.

Electrics

Test all electrical components, including lights, windows, and infotainment systems. Ensure the air conditioning works effectively. Look for signs of electrical faults, such as flickering lights or malfunctioning displays.

MOT History

Review the MOT history for any past failures or advisories. This information can provide insights into potential issues. Use the DVSA MOT history service for a detailed report on the vehicle’s past.

Use Honest Car Check to verify mileage and MOT history. This will help ensure you are making a sound investment.
