36.0%Daewoo Matiz
1,838 tests · 57,123 avg mi · 57.6% pass
The Matiz sits at #1 on this list with a 36.0% outright fail rate despite averaging only 57k miles at the time of test — that gap between mileage and failure rate is the red flag. The two most common failure points 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 and a defective headlamp lens. Few failures are fixable at the station, meaning most VT30s are carried home.
