MG ZS — MOT Reliability Overview

The MG ZS has an average MOT pass rate of 68.9%, which is 14.2 percentage points below the MG brand average of 83.1%. This is a reasonable result that reflects typical UK reliability standards. Regular servicing and addressing advisories promptly will help keep your ZS on the road.

The most common reasons a MG ZS fails its MOT are the strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, parking brake efficiency below minimum requirement, a transmission shaft constant velocity joint boot missing or no longer prevents the ingress of dirt etc. If you are preparing your ZS for its MOT, checking these areas first could save you a retest fee. Our detailed fault analysis includes estimated repair costs for each failure type.

Before buying a used MG ZS, we recommend checking the full MOT history, write-off status, outstanding finance, and stolen vehicle status. These checks can be done for free using the registration number.
