Used BMW i3: Common Problems Before Buying

The BMW i3 is a unique electric vehicle that has captured the attention of many buyers looking for an eco-friendly option. However, before you dive into a purchase, it’s essential to be aware of the common problems associated with this model. From battery health to MOT issues, understanding these factors can help you make a more informed decision. The i3 boasts an impressive MOT pass rate of 89.1%, based on 2,536 DVSA MOT tests analysed by CarBuyerIQ, which is significantly higher than the national average of 79.1%. But like any used car, it has its quirks and potential pitfalls.

Key facts

• The BMW i3 has an MOT pass rate of 89.1% based on 2,536 DVSA MOT tests analysed by CarBuyerIQ.
• The most common MOT problem areas include tyres (55.3%), brakes (18%), and lights (9.1%).
• The fail rate for i3 models under 40,000 miles is 9%, while those between 40,000 and 80,000 miles have a 12.5% fail rate.
• The i3 ranks 20th out of 386 cars for MOT pass rates, indicating a relatively reliable vehicle.
• Battery health and degradation are crucial factors to consider when buying a used i3.

Understanding Battery Health: What to Check and Expect

Battery health is one of the most critical aspects to consider when purchasing a used BMW i3. The i3 is equipped with a lithium-ion battery that can degrade over time, affecting its range and performance. Generally, you can expect the battery to retain about 70-80% of its capacity after several years of use, but this can vary significantly based on driving habits and charging practices.

When inspecting a used i3, ask the seller about the battery's health. You can also check the vehicle's history through the CarBuyerIQ Vehicle Check, which provides insights into the battery's condition and any previous issues. Look for signs of battery degradation, such as reduced range, which can be a red flag. If the seller has documentation of battery health checks or any replacements, that’s a positive sign.

Additionally, consider the age of the i3. Models manufactured earlier in the production run may have more significant battery degradation than newer ones. If you’re looking at an i3 that has been on the road for several years, it’s wise to have a professional inspect the battery. This can save you from unexpected costs down the line, especially if you need to replace the battery, which can be quite expensive.

Real-World Range vs Manufacturer Claims

One of the standout features of the BMW i3 is its electric range. The manufacturer claims a range of around 160 to 180 miles on a full charge, depending on the model and driving conditions. However, real-world usage often tells a different story. Factors such as driving style, weather conditions, and the use of climate control can significantly impact the actual range.

In practice, many i3 owners report achieving around 120 to 150 miles under typical driving conditions. If you plan to use the i3 for longer journeys, it’s essential to factor in these real-world figures. When considering a used i3, ask the seller about their experience with the vehicle's range. If they frequently found themselves needing to charge more often than expected, it could indicate battery issues or that the car has been driven hard.

Furthermore, the i3's range can be affected by its age and battery health. Older models may not perform as well as newer ones, so keep that in mind when comparing options. If you’re keen on understanding how the range has held up over time, checking the MOT history for any recorded issues related to battery or electrical systems can provide valuable insights.

Charging Costs and Infrastructure

Charging costs are another vital consideration when looking at a used BMW i3. Charging at home is typically cheaper than using public charging stations, but the costs can vary based on your electricity provider and the time of day you charge. On average, charging an i3 at home can cost around £5 to £7 for a full charge, depending on your electricity rates.

Public charging stations can be more expensive, especially fast chargers. Depending on the provider, you might pay anywhere from £0.20 to £0.60 per kWh. If you plan to rely on public charging, it’s worth researching local charging networks and their pricing structures. The i3 supports both AC and DC charging, which means you have flexibility in how you charge it.

Another factor to consider is the availability of charging infrastructure in your area. If you live in a region with limited charging stations, it may be more challenging to keep the i3 charged, especially if you don’t have access to home charging. Before committing to a purchase, check the GOV.UK road tax site for any local incentives or charging schemes that could benefit you.

Common Problems Specific to the BMW i3

While the BMW i3 is generally well-regarded, it’s not without its issues. Here are some common problems that buyers should be aware of:

1. Tyre Wear

Tyres are the most common area of concern for the i3, accounting for 55.3% of defects and advisories recorded during MOT tests. Given the i3's lightweight design and electric motor, it can be quite responsive, which may lead to uneven tyre wear if not properly maintained. Always check the tread depth and look for any signs of uneven wear when inspecting a used model.

2. Brake Issues

Brakes are another area where i3 owners have reported problems, with 18% of defects related to this system. The regenerative braking system in electric vehicles can sometimes lead to unusual wear patterns, so it’s crucial to ensure that the brakes are in good condition. Listen for any unusual noises during a test drive, and check the brake pads and discs for wear.

3. Electrical Problems

As with many electric vehicles, the i3 can experience electrical issues. These might range from minor glitches in the infotainment system to more serious problems with the battery management system. If you notice any warning lights on the dashboard or issues with the car's electronics, it’s worth having a professional check it out before you buy.

4. Suspension Wear

Suspension issues account for 3.2% of defects in the i3. Given the car's unique construction and lightweight materials, the suspension components can wear differently than in traditional vehicles. Pay attention to how the car handles on the road; any knocking or unusual noises could indicate suspension problems.

5. Bodywork and Interior Wear

The i3 features a distinctive design, but its materials can show wear over time. Check for any signs of damage to the bodywork, especially around the edges of the doors and the wheel arches. Inside, the unique materials used for the dashboard and seats can wear differently than traditional leather or fabric, so inspect these areas carefully.

Running Cost Savings vs Petrol/Diesel

One of the main advantages of owning a BMW i3 is the potential for savings on running costs compared to petrol or diesel vehicles. Electric vehicles typically have lower fuel costs, with charging often being cheaper than filling up a petrol tank. On average, you might save around £1,000 to £1,500 annually on fuel costs alone, depending on your driving habits.

Insurance costs can also be lower for electric vehicles, although this can vary based on the model and your personal circumstances. The i3 falls into various insurance groups, so it’s worth checking the Thatcham insurance groups to find out where it stands.

Additionally, electric vehicles often have lower maintenance costs, as they have fewer moving parts than traditional combustion engines. However, keep in mind that battery replacement can be a significant expense if it becomes necessary. Overall, while the i3 may have a higher upfront cost compared to some petrol or diesel alternatives, the long-term savings can make it a financially sound choice.

Dave's Verdict: Is It Worth Going Electric?

The BMW i3 is a compelling option for those looking to transition to electric driving. With its unique design, decent range, and relatively high MOT pass rate of 89.1%, it stands out in the crowded EV market. However, potential buyers should be aware of the common problems associated with the i3, particularly regarding battery health and tyre wear.

Before making a purchase, it’s crucial to conduct thorough research. Check the vehicle's history using the CarBuyerIQ Vehicle Check to uncover any hidden issues. Pay attention to the battery's condition, and don’t hesitate to ask for documentation regarding its health. If you’re considering a used BMW i3, it’s worth weighing the pros and cons carefully, but for many, the benefits of going electric can outweigh the drawbacks.

In conclusion, the BMW i3 can be a fantastic choice for eco-conscious drivers, provided you do your homework. With the right checks and balances in place, you could find yourself behind the wheel of a reliable, stylish electric vehicle that serves you well for years to come.
