The surprising truth about Dacia Sandero MOT failures
It's not the gearbox or the engine that frequently lands the Dacia Sandero in MOT trouble, but humble lighting and electrical systems. This category accounts for 30% of all defects recorded in national DVSA MOT data for the model, a figure far higher than commonly assumed for mechanical issues. This suggests that while the Sandero maintains its reputation for robust, no-frills engineering, its Achilles' heel is far more prosaic than buyers might expect.
Where the Sandero typically falls short
Across all Dacia Sandero models for which we hold data, DVSA MOT records show a consistent pattern. After lighting and electrical issues at 30%, the next most common defect category is visibility, primarily windscreen and wiper faults, at 19%. Brakes follow, making up 17% of failures, often indicating routine wear and tear rather than fundamental design flaws. More complex areas like the drivetrain account for 11% of defects, and suspension for 9%. This distribution highlights that most Sandero MOT issues are either easily preventable or straightforward to repair, rather than costly mechanical breakdowns.
MOT performance across its lifetime
The Dacia Sandero shows a clear decline in MOT pass rates as it ages. At its first MOT, typically around three years old, the model achieves a respectable 90% pass rate. However, when examining records for every age of the Dacia Sandero we hold data for, this average pass rate drops to 78.2%. This divergence suggests that while initially robust, consistent maintenance becomes increasingly crucial for Sandero owners as their vehicles get older to maintain MOT compliance.
How we worked this out
Our insights are built from national DVSA MOT test data for the UK market. We analyse millions of test records, focusing on models with a meaningful number of tests behind them – in this case, over 98,215 vehicles with history for the Dacia Sandero. Our reliability analysis examines the typical failure points and categories, helping buyers understand what issues are most common. It is important to note that a car presenting for an MOT is not necessarily representative of the entire fleet, and failures often cluster around areas that are neglected or prone to wear over time. These figures represent a statistical overview of the model’s performance, not a guarantee of any individual car's condition or a comparison against other models on the market.
What to do with this information
Understanding the Dacia Sandero's typical MOT failure points can inform your pre-MOT checks. Prioritise inspection and maintenance of all lighting elements, from headlamps to number plate lights, and ensure wipers are in good condition and the windscreen is free from damage. Regular brake checks and servicing are also prudent. When buying a used Sandero, review its MOT history for recurring issues in these areas. While the data shows common pitfalls, these are often manageable with diligent ownership, helping your Sandero pass its MOT with confidence.
