2012 Nissan Micra 1.2L Petrol · PE12 BZA

The 2012 Nissan Micra presents a concerning mechanical narrative marked by a progressive deterioration of safety-critical systems rather than gradual decline. After passing in 2025 with no recorded defects, the vehicle suffered a significant failure in April 2024 involving both front and rear suspension arm bushings, a front service brake binding issue, and multiple rear brake system failures including loss of effort and inoperability of one parking bracket. A second failure occurred in April 2023 with dangerously severe issues including a completely non-functional rear service brake on one side, inoperative right-side parking brake, and rear brake imbalance. The most recent test on March 26, 2026, returned a pass but only with minor observations, which masks the underlying pattern of escalating mechanical distress that has built up over the past three years. While the latest result appears positive, the cumulative weight of earlier failures suggests the vehicle has not been in continuous safe operation and requires immediate attention to the identified weak points before considering purchase. The mileage figure of 45,232 miles on a fourteen-year-old vehicle represents an anomalously low accumulation rate of approximately 3,231 miles per annum compared to typical daily-use vehicles of this era. This extremely slow mileage increase implies either very limited driving activity or prolonged periods of storage between uses, which may have allowed minor components to degrade slowly while preventing more frequent replacement events. The timing of the 2024 and 2023 failures—both occurring within short intervals of just under one year apart—contrasts sharply with the low mileage figure and indicates that the vehicle experienced concentrated mechanical stress during brief periods of active use rather than sustained high-mileage wear. The gap between the February 2022 pass and the March 2023 failure shows how quickly the same vehicle can transition from acceptable to critically unsafe status when subjected to even modest driving volumes, making the current low-mileage reading somewhat misleading regarding the true extent of accumulated wear on critical components. The suspension system warrants particular scrutiny given the two major failures in 2024 affecting both front and rear wishbone bushes and pins. These components control vertical and lateral movement of the wheels and their excessive wear would manifest as a pronounced clunking or knocking over bumps during a test drive, accompanied by a noticeable play in the steering when loaded. The front and rear service brake binding reported in 2024 suggests potential pad wear or caliper blockage that could compromise braking performance, particularly under hard application. Additionally, the 2023 failure showing zero effort on the rear service brake and complete inoperability of the right-hand parking brake represent serious safety hazards that demand verification through a full brake system inspection. If purchased, the buyer should expect to spend considerable time diagnosing and replacing worn suspension bushings, servicing the service brakes, and repairing the parking brake mechanism before the vehicle can be considered roadworthy. Finally, the tire condition noted in the most recent MOT—nearside front tyres worn close to legal limits and appearing worn on the edge—should be examined closely for alignment-related causes such as uneven wear patterns or camber drift that might also affect the suspension geometry. Given the history of suspension failures, the tire wear could be exacerbated if the suspension isn't properly aligned, leading to accelerated degradation of the remaining tread. The combination of low mileage, the documented pattern of progressive brake and suspension failures, and the current minor tyre wear creates a scenario where the vehicle's mechanical reliability is compromised despite the recent passing. A thorough hands-on inspection focusing on suspension bushings, brake line condition, parking brake function, and proper tyre alignment before committing to purchase is essential to mitigate the risks associated with this car's recorded history.
