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

TL;DR
The MG ZS has common faults including electrical issues, coolant leaks, suspension problems, brake wear, and infotainment glitches. Many of these can be fixed DIY, saving costs on parts and labour, which can range from £20 to £300 depending on the issue.
Electrical Issues
One common fault in the MG ZS is electrical problems, particularly with the central locking system. This can often be traced to a faulty actuator. A DIY fix involves checking fuses and replacing the actuator, which costs around £30 for parts. If you go to a garage, expect to pay £50 to £80 for labour.
Coolant Leaks
Coolant leaks are another frequent issue, especially in models from 2017 to 2020. The problem often arises from a worn radiator or hose. Replacing a hose can be a DIY job, costing about £20 for parts. A garage might charge £100 to £150 for a full radiator replacement, including labour.
Suspension Problems
Suspension issues, particularly with the front struts, are reported in various MG ZS models. Replacing struts can be done at home with the right tools, costing around £100 for parts. However, garages may charge £200 to £300 for the entire job, including labour.
Brake Wear
Brake wear is common in many vehicles, including the MG ZS. If you hear squeaking, it may be time to replace the pads. This is a straightforward DIY task, with parts costing about £50. A garage may charge £100 to £150 for the same work.
Infotainment System Glitches
Some owners have reported issues with the infotainment system freezing. A simple reset may resolve this, but if the issue persists, a software update may be required. DIY updates are often possible, but a garage might charge £50 to £100 for diagnostics and updates.
