Dacia Spring MOT failure rates: what to expect
What fails on a Dacia Spring at MOT, how often, and what each fix typically costs.

The Dacia Spring is a compact electric vehicle that has gained popularity in the UK. However, like any car, it can encounter issues that may lead to an MOT failure. Common problems include issues with lights, brakes, and suspension components. Fixing these problems can vary in cost, so understanding what to expect is essential for owners.
Common MOT Failures in the Dacia Spring
The most frequent reasons for MOT failures in the Dacia Spring include lighting issues, brake performance, and suspension problems. According to DVSA MOT data, these areas are often highlighted during inspections. Addressing these issues promptly can help ensure your vehicle passes its MOT.
Lighting Issues
Lighting problems are among the top reasons for MOT failures in the Dacia Spring. Common faults include blown bulbs, misaligned headlights, or defective indicators. These issues can usually be identified during a pre-MOT check.
Fixing lighting issues typically involves replacing bulbs or adjusting the headlight alignment. The cost for bulb replacement is relatively low, often ranging from £5 to £20, while more complex electrical issues may require professional diagnostics, which can cost between £50 and £100.
Brake Performance
Brakes are critical for safety, and any issues can lead to an MOT failure. Common brake-related problems in the Dacia Spring include worn brake pads, disc wear, or fluid leaks. Regular maintenance can help prevent these issues from escalating.
Replacing brake pads usually costs between £100 and £200, depending on the garage and whether you opt for OEM or aftermarket parts. If the brake discs also need replacing, this can add another £150 to £300 to the total cost. Ensuring your brakes are in good condition before the MOT can save you time and money.
Suspension Problems
Suspension components, such as shock absorbers and springs, can wear out over time, leading to MOT failures. Symptoms of suspension issues may include excessive bouncing, uneven tyre wear, or knocking noises when driving over bumps.
Repairing or replacing suspension components can vary significantly in cost. Replacing shock absorbers may cost between £100 and £300 per pair, while springs can range from £80 to £150 each. Regular checks can help identify these issues early, potentially avoiding costly repairs.
Tyre Condition
Tyres are another common area of concern during an MOT. The Dacia Spring must have tyres that meet legal tread depth requirements and are free from significant damage. Worn or damaged tyres can lead to an automatic failure.
Replacing tyres can vary in cost based on brand and size. Budget tyres may start at around £40 each, while premium options can exceed £100. Regularly checking your tyres for wear and maintaining proper pressure can help you avoid MOT failures related to tyre condition.
Emissions Testing
Although the Dacia Spring is an electric vehicle and does not produce traditional exhaust emissions, it is still subject to certain environmental checks during the MOT. Any issues with the battery or electrical systems that affect performance can lead to a failure.
If the vehicle’s battery is not holding a charge or there are issues with the electric motor, repairs can be costly. Battery replacement can range from £1,000 to £3,000, depending on the model and warranty status. Regular servicing can help maintain battery health and performance.
Bodywork and Structural Integrity
While not as common, issues with bodywork and structural integrity can also lead to MOT failures. Rust, corrosion, or damage to the chassis can be flagged during the inspection. These issues may arise from poor maintenance or exposure to harsh weather conditions.
Repairing bodywork can vary widely in cost. Minor rust repairs might cost around £100 to £300, while more extensive structural repairs could exceed £1,000. Keeping your vehicle clean and protected from the elements can help prevent these issues from developing.
Understanding the common MOT failures associated with the Dacia Spring can help owners prepare for inspections and avoid unexpected repair costs. Regular maintenance and pre-MOT checks can significantly improve the chances of passing the test, ensuring your vehicle remains safe and roadworthy.
