2016 Mazda 3 2.0L Petrol · OV66 ENK

The 2016 Mazda 3 presents a mixed roadworthiness picture characterised by intermittent rear-end concerns that recurred across multiple MOT cycles before stabilising in late 2025. A major failure occurred in October 2020 when an offside rear coil spring fractured (5.3.1 (b) (i)), followed by thin rear brake pads recorded in September 2023 (1.1.13 (a) (ii)). An advisory for worn-offside front tyres persisted from September 2021 onward (5.2.3 (e)), indicating continued tyre wear despite no intervening failures. While the vehicle passed its most recent MOT on 2025-09-04 with no defects, the historical pattern of rear-suspension degradation and tyre wear warrants caution for buyers considering this model. With 74,563 miles recorded after approximately ten years of ownership, the average annual mileage of 7,456 miles aligns with typical consumption for a Mazda 3 of this era. The gap between the 2020 major failure and the 2023 advisory marks a period of accelerated rear-system deterioration, while the absence of further failures through 2024 suggests some recovery or reduced load on the affected components. However, the sustained tyre advisory since 2021 indicates that the front tyres have remained under significant stress throughout the vehicle's operational life, potentially accelerating lateral wear and affecting handling balance. Regarding the rear brake system, inspect the rear brake pads during low-speed deceleration for any audible grinding or vibration that could signal pad wear combined with potential rotor contamination. Given the prior coil spring failure, also examine the rear suspension bushings and mounting points for signs of fatigue, excessive play, or visible damage that might affect braking geometry. The rear brake caliper housing should be checked for coolant residue or oil leakage that could compromise hydraulic function. The front tyres require regular visual inspection for uneven wear patterns, particularly on the outer edges where the advisory noted the tyres were worn close to legal limits and appearing worn on the edge. Check the tyre sidewalls for any cuts or bulges that could indicate hidden damage. Additionally, given the history of rear-end issues, consider having the entire rear suspension system inspected by a competent technician before purchase, focusing on the coil spring, control arm bushings, and brake line connections, as these are the components most likely to have accumulated damage over the reported timeline.
