The Real MOT Pitfall for the Hyundai I20
When a car heads in for its MOT, many drivers brace for common wear-and-tear issues like tyres or brakes. But for the Hyundai I20, national DVSA MOT data reveals a different story: it's not the routine mechanicals that cause the most grief, but rather its electrical and lighting systems. This category accounts for a significant 31% of all failures, catching out owners far more often than other, seemingly more critical, components.
Beneath the Bonnet: Where the I20 Stumbles
Across every age of the I20 we track, the data, drawn from 124,669 vehicles with MOT history, paints a clear picture. After lighting and electrical failures at 31%, the next most common issues are found in the braking system, responsible for 22% of failures. Visibility issues, largely related to windscreens and wipers, follow with a 14% share, closely trailed by suspension problems at 13%. Tyres, often a primary concern for drivers, contribute 12% to the failure count, making them less of an outlier than reputation might suggest.
Ageing Gracefully? The I20's MOT Journey
Like most cars, the Hyundai I20 performs significantly better in its early years. Its first MOT, typically around three years old, sees a strong 94.6% pass rate. However, as the cars age, this figure dips. Across every model year and age we hold data for, the average pass rate sits at 80.5%. This indicates that while the I20 starts strong, the accumulation of minor issues, particularly in its electrical architecture, begins to take its toll as the years pass.
How We Worked This Out
Our analysis for the Hyundai I20 is built on tens of millions of entries in the national DVSA MOT test records. We track models with a meaningful number of tests behind them across the UK market, aggregating their performance across different ages and model years. This allows us to identify common failure points specific to individual models. It's important to remember that a pass rate reflects the condition of cars presented for testing, not necessarily the overall reliability of every car on the road. Failures often cluster with age, mileage, and maintenance habits, rather than being an inherent flaw of a badge. Our insights are descriptive fleet statistics for the models we track, not a direct comparison against the entire UK market.
What To Do With This Data
If you own a Hyundai I20 or are considering buying one, these figures offer a practical guide for pre-MOT checks. Prioritise a thorough inspection of all lighting components – headlights, brake lights, indicators, and interior lights – as well as checking the functionality of all electrical accessories. Beyond this, paying attention to brake wear, windscreen condition, and suspension noises will address the next most common failure points. Always request a full MOT history when buying a used car to understand its specific maintenance journey. You can explore more models and their MOT performance in our full MOT reliability series.
