Top Mazda CX-5 fixes every owner should know
Cheap, practical fixes for the Mazda CX-5 faults you actually meet, with rough costs and what a garage will charge.

TL;DR
The Mazda CX-5 has several common faults that can be easily addressed. Key issues include air conditioning problems and suspension wear, with practical DIY solutions available. Repair parts are generally affordable, while garage labour costs range from £50 to £100 per hour.
1. Air Conditioning Issues
Many Mazda CX-5 owners report problems with the air conditioning system, particularly in models from 2012 to 2017. A common fix is recharging the refrigerant, which you can often do yourself with a recharge kit costing around £30. If you need to diagnose a leak or repair components, expect garage costs to be around £100 to £200.
2. Worn Suspension Components
Suspension wear is a frequent issue, especially in older models (2013-2018). Common symptoms include a bumpy ride and excessive noise over bumps. Replacing worn shock absorbers or bushings can be a DIY job, with parts costing approximately £50 to £150. If you opt for a garage, labour costs can range from £60 to £120.
3. Electrical Problems
Electrical issues, such as faulty window switches or dashboard lights, can arise in various model years. Diagnosing these problems can be tricky. Simple fixes, like replacing a switch, can be done at home for about £20. More complex electrical repairs might require professional help, costing upwards of £80 to £150.
4. Brake Pad Wear
Brake pad wear is common in the CX-5, particularly in city driving conditions. Replacing brake pads is a straightforward DIY task, with parts ranging from £30 to £80. If you have a garage do the work, expect to pay around £100 to £200, including labour.
5. Exhaust System Issues
Exhaust leaks or failures are reported in models from 2012 to 2017. A temporary fix might involve using exhaust tape, which costs about £10. However, for a proper repair, replacing the faulty section of the exhaust can cost between £100 and £300 at a garage, depending on the extent of the damage.
