More on the Mazda CX-5
TL;DR
The Mazda CX-5 is generally a reliable vehicle, but it has some common faults to watch for. Key areas of concern include engine issues, transmission problems, and electrical faults, particularly in earlier models. Regular maintenance is essential for ensuring long-term reliability.
Engine Problems
The Mazda CX-5 has faced several engine issues, particularly with the 2.2-litre diesel engine found in models from 2012 to 2017. Owners have reported turbocharger failures and excessive oil consumption. The petrol engines are generally more reliable, but it’s still wise to check service history for any signs of neglect. Additionally, there have been reports of DPF (Diesel Particulate Filter) blockages, especially in vehicles that are frequently used for short trips, leading to reduced performance and increased emissions.
Transmission Issues
Automatic transmission problems have been noted primarily in CX-5 models from 2013 to 2016. Symptoms include rough shifting and delayed engagement when changing gears. If you are considering a used CX-5, take it for a test drive to ensure the transmission operates smoothly. Some owners have also mentioned that the transmission can occasionally feel unresponsive, particularly when accelerating from a stop, which can be concerning for potential buyers.
Suspension Concerns
Some owners have reported suspension issues, especially in earlier models. Problems can include premature wear on the front suspension components, leading to noise and handling issues. Regular checks can help identify these problems before they worsen. Additionally, some drivers have noted that the ride can feel a bit firm on rough roads, which may not be to everyone’s taste, but it contributes to the vehicle’s sporty handling characteristics.
Electrical Faults
Electrical problems have been reported in CX-5 models from 2012 to 2015. Issues include malfunctioning infotainment systems and dashboard warning lights that may not accurately reflect the vehicle’s status. A thorough inspection of the electrical system is advisable when purchasing a used model. Owners have also mentioned that the keyless entry system can sometimes be finicky, leading to frustration when trying to unlock or start the vehicle.
Recalls and Safety
Certain Mazda CX-5 models have been recalled for safety issues. The 2016 model, in particular, had recalls related to airbag faults and potential fuel leaks. Always check the DVSA website for any outstanding recalls before buying. It’s also worth noting that some earlier models had issues with the power liftgate, which could fail to operate correctly, especially in colder climates where ice might interfere with the mechanism.
