MG ZT — MOT Reliability Overview

The MG ZT has an average MOT pass rate of 70.1%, which is 13.0 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 ZT on the road.

If you are preparing your ZT 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.
