The BMW i3 has been on the market since 2014, and its unique design and electric capabilities have made it a popular choice for environmentally conscious drivers. However, like any used vehicle, it’s crucial to delve into its MOT history to understand its reliability and potential pitfalls. This guide will explore the various aspects of the i3's MOT history, helping you make an informed decision.

Understanding the BMW i3's MOT Pass Rate

The BMW i3's MOT pass rate of 89.1% is significantly higher than the national average of 79.1%. This impressive figure indicates that the i3 is generally a reliable vehicle, with fewer issues that lead to MOT failures compared to other models. Ranking 20th out of 386 cars based on MOT pass rates further solidifies its reputation as a dependable choice.

When considering the i3, it’s essential to understand that a higher pass rate often correlates with better build quality and maintenance practices. This can be attributed to the vehicle's design and the fact that many i3 owners are likely to be more conscientious about upkeep, given the nature of electric vehicles and their typically higher initial investment.

However, it’s important to note that while the pass rate is encouraging, it doesn't guarantee that every used i3 will be free from issues. Always check the specific MOT history of the vehicle you’re considering. You can do this easily through the GOV.UK MOT history service, which provides detailed records of past tests, including any advisories and failures.

Common MOT Problems for the BMW i3

Diving deeper into the BMW i3's MOT history reveals common problem areas that prospective buyers should be aware of. The most frequent issues noted during MOT tests for the i3 include:

• Tyres (55.3%): A staggering majority of defects and advisories stem from tyre-related issues. This could range from worn tread to incorrect pressures. Given the i3's lightweight design, it’s crucial to ensure that the tyres are in good condition to maintain optimal performance and safety.
• Brakes (18%): Brake issues are the second most common problem area. This could involve worn brake pads or issues with the braking system itself. Regular checks and timely replacements are essential for safety.
• Lights (9.1%): Problems with lights, including headlights and indicators, are also prevalent. Ensuring that all lights are functioning properly is not only crucial for passing the MOT but also for safe driving.
• Windscreen (5.2%): Windscreen defects, such as chips or cracks, can lead to advisories or failures. Given the importance of visibility, addressing these issues promptly is vital.
• Suspension (3.2%): While less common, suspension issues can arise, particularly in older models. Regular checks can help identify any potential problems before they escalate.

Understanding these common issues can help you approach your potential purchase with a more informed mindset. If you’re considering a used BMW i3, it’s wise to have a thorough inspection done, focusing on these areas.

MOT Fail Rates by Mileage

The MOT fail rates for the BMW i3 also provide valuable insights into its reliability as it ages. For vehicles with mileage under 40,000 miles, the fail rate is a mere 9%. This is a reassuring figure, suggesting that lower-mileage i3s are generally in good condition. However, as mileage increases, the fail rate rises to 12.5% for those between 40,000 to 80,000 miles.

This trend is not uncommon across many vehicle models, as wear and tear become more pronounced with higher mileage. If you’re looking at a higher-mileage i3, it’s essential to scrutinise its maintenance history and consider whether any significant repairs have been undertaken. A well-maintained vehicle with a solid service record can still be a great choice, even with higher mileage.

Battery Health: What to Check and Expect

One of the most critical aspects of owning an electric vehicle like the BMW i3 is understanding its battery health. The i3 is equipped with a lithium-ion battery that, like all batteries, can degrade over time. When considering a used i3, it’s essential to assess the battery's condition, as this directly impacts range and performance.

Typically, the i3's battery should retain around 70-80% of its capacity after several years of use. However, various factors can influence battery health, including charging habits, driving style, and climate conditions. If you're looking at a used i3, ask the seller about the battery's history, including any replacements or significant issues.

You can also check the battery's state of health using diagnostic tools or by consulting a specialist. Understanding the battery's condition can help you gauge how much range you can expect and whether any future replacements might be necessary.

Real-World Range vs Manufacturer Claims

When it comes to electric vehicles, real-world range can often differ significantly from manufacturer claims. The BMW i3 is marketed with a range of approximately 160 miles on a full charge. However, various factors can affect this figure, including driving conditions, temperature, and driving style.

In real-world scenarios, many i3 owners report achieving around 120 to 140 miles under normal driving conditions. This is still a respectable figure, especially for urban driving, where the i3 excels. However, if you plan to use the vehicle for longer journeys, it’s wise to consider how often you’ll need to charge and whether the available charging infrastructure meets your needs.

Charging times can also vary, with a standard home charger taking around 4-6 hours for a full charge. If you opt for a rapid charger, you can achieve around 80% charge in about 30 minutes, making it more convenient for longer trips.

Running Cost Savings vs Petrol/Diesel

One of the significant advantages of owning an electric vehicle like the BMW i3 is the potential for running cost savings compared to traditional petrol or diesel vehicles. The cost of electricity for charging is typically lower than the equivalent cost of petrol or diesel, leading to substantial savings over time.

For instance, charging the i3 at home can cost around £3 to £5 for a full charge, depending on your electricity tariff. In contrast, a petrol vehicle might cost significantly more to cover the same distance. Additionally, electric vehicles often benefit from lower road tax rates and exemptions from congestion charges in certain areas, further enhancing their cost-effectiveness.

However, it’s essential to consider the initial purchase price of the i3, which can be higher than that of a comparable petrol vehicle. Despite this, the long-term savings on fuel and maintenance can make the i3 a financially sound choice.

Common Problems Specific to the BMW i3

While the BMW i3 is generally reliable, there are some common problems that owners have reported. Understanding these issues can help you make a more informed decision when purchasing a used model.

One of the most frequently mentioned problems is related to the vehicle's electronics. Some owners have reported issues with the infotainment system, including glitches and connectivity problems. While these issues can often be resolved with software updates, they can be frustrating for users.

Another area of concern is the vehicle's range extender model, which, while providing additional range, has been known to have its own set of issues. If you’re considering this model, ensure that it has been well-maintained and that any necessary repairs have been carried out.

Additionally, as mentioned earlier, tyre wear is a common issue, particularly due to the i3's lightweight design. Regular checks and replacements are essential to ensure safety and performance. For more insights into common problems, refer to our guide on common problems before buying.

Dave's Verdict: Is It Worth Going Electric?

The BMW i3 presents a compelling case for those considering an electric vehicle. With its impressive MOT pass rate, relatively low fail rates, and potential for significant running cost savings, it stands out as a reliable option in the used car market. However, as with any vehicle, it’s essential to do your due diligence.

Before making a purchase, check the specific MOT history of the vehicle you’re considering, paying particular attention to common problem areas like tyres and brakes. Additionally, assess the battery health and real-world range to ensure it meets your needs.
