Subaru Solterra MOT failure rates: what to expect

What fails on a Subaru Solterra at MOT, how often, and what each fix typically costs.

The Subaru Solterra is a modern electric vehicle that has garnered attention for its eco-friendly credentials. However, like any car, it can encounter issues that may lead to MOT failures. Common problems include battery-related issues, lighting faults, and suspension wear, with repair costs varying based on the severity of the issue.

Battery and Electrical Issues

One of the most common reasons for MOT failures in the Subaru Solterra is related to the battery and electrical systems. This includes faults with the high-voltage battery, wiring, and charging systems. If the battery fails to hold a charge or shows signs of degradation, it can lead to an automatic failure during the MOT.

Repairing battery-related issues can be costly. A new battery for an electric vehicle can range from £2,000 to £5,000, depending on the model and specifications. Additionally, wiring repairs can cost between £150 and £500, depending on the extent of the damage. Regular checks and maintenance can help mitigate these issues before the MOT.

Lighting and Visibility Failures

Lighting and visibility problems are another frequent cause of MOT failures. This includes malfunctioning headlights, brake lights, and indicators. The Solterra, like all vehicles, must have fully functioning lights to pass the MOT. Issues can arise from blown bulbs, faulty wiring, or even moisture ingress in the light units.

Replacing a bulb is relatively inexpensive, typically costing between £10 and £20. However, if the issue lies within the wiring or the light unit itself, costs can escalate to £100 or more for repairs or replacements. Ensuring all lights are functioning before the MOT can save time and money.

Suspension and Steering Problems

Wear and tear on suspension and steering components can lead to MOT failures. Common issues include worn shock absorbers, damaged bushings, and misaligned steering. These problems can affect the vehicle’s handling and safety, making them critical for passing the MOT.

Repair costs for suspension issues can vary widely. Replacing shock absorbers can cost between £150 and £300 per pair, while more extensive repairs, such as replacing control arms or steering racks, can run from £300 to £800. Regular inspections can help identify these issues early, potentially avoiding costly repairs.

Brake System Failures

The braking system is vital for safety and is closely scrutinised during the MOT. Common failures in the Subaru Solterra can include worn brake pads, damaged discs, or leaks in the brake lines. Any issues with the braking system can lead to an automatic failure, making it essential to keep this system in good condition.

Replacing brake pads typically costs between £100 and £200, while disc replacements can add another £150 to £300. If there are issues with the brake lines or master cylinder, repairs can escalate to £500 or more. Regular maintenance and timely replacements can prevent unexpected failures during the MOT.

Tyre Wear and Condition

Tyres are a critical safety component and are closely examined during the MOT. The Solterra, being an electric vehicle, may experience uneven tyre wear due to its weight and torque characteristics. Common issues include tread wear below the legal limit and sidewall damage.

Replacing tyres can be a significant expense, with costs ranging from £70 to £150 per tyre, depending on the brand and specifications. Regularly checking tyre pressure and tread depth can help ensure they remain within legal limits and avoid MOT failures.

Exhaust and Emissions Testing

Although the Subaru Solterra is an electric vehicle and does not have a traditional exhaust system, any associated components, such as the heating system or regenerative braking, can still be subject to scrutiny during the MOT. Issues related to emissions can arise if the vehicle’s systems are not functioning correctly.

While the Solterra is less likely to face emissions-related failures, if there are faults with the heating or cooling systems, repairs can cost between £200 and £600, depending on the complexity of the issue. Regular maintenance can help ensure all systems are functioning correctly, reducing the risk of MOT failures.

By staying informed about common issues and their associated costs, Subaru Solterra owners can better prepare for their MOT and ensure their vehicle remains safe and roadworthy.
