EV Breakdowns: What UK Drivers Need to Know

Embracing the electric vehicle (EV) revolution is an exciting step for many UK motorists, offering a quieter, cleaner, and often more cost-effective way to travel. However, for those considering their first EV, common questions often arise, particularly concerning reliability and the dreaded possibility of a breakdown. The thought of being stranded, especially with a new type of vehicle, can be daunting. So, let's delve into the realities of EV breakdowns, their common causes, and what you, as a responsible driver, need to know to stay safe and mobile.

The good news is that the lifespan of an EV is remarkably similar to that of a traditional petrol or diesel vehicle. While they are packed with cutting-edge technology, electric cars do still break down, though often less frequently than their internal combustion engine (ICE) counterparts. This improved reliability stems from fundamental design differences, but it’s crucial to understand where potential issues might arise.

How Long Do Electric Cars Last? Understanding EV Lifespan

When investing in a new vehicle, longevity is a key consideration, and electric cars are proving to be just as durable as their petrol and diesel predecessors, if not more so in some aspects. Modern EVs are engineered to withstand the rigours of daily driving for many years, with their core components designed for extended lifespans. The perception that electric cars are fragile or short-lived is largely a misconception from the early days of the technology. Today, manufacturers are confident in their products, often backing them with substantial warranties, particularly for the most critical component: the battery.

The overall lifespan of an EV is influenced by several factors, including driving habits, maintenance, and environmental conditions. However, the inherent simplicity of the electric powertrain contributes significantly to its durability. Fewer moving parts mean less wear and tear, and consequently, a reduced likelihood of mechanical failure over time.

Common Causes of Electric Car Breakdowns

While EVs boast superior reliability in many areas, they are not immune to issues. Understanding the most common breakdown causes can help you prepare and potentially prevent them.

The Electric Powertrain: A Simpler Design

One of the primary reasons for an EV's enhanced reliability is its engine. Electric motors are inherently simpler than petrol or diesel engines, containing significantly fewer moving parts. This reduction in complexity means there are fewer components to wear out or fail, leading to improved overall reliability and reduced maintenance requirements. Unlike ICE vehicles, there's no conventional clutch, gearbox, or oil filter to worry about, eliminating these common breakdown risks entirely. This streamlined design translates directly into fewer opportunities for mechanical failure.

Key Components Prone to Issues

Despite the robust electric motor, certain components in an EV are still subject to wear and tear or can experience issues, much like any other road-going vehicle. The most common problems you are likely to face with an electric car typically involve the in-car electrics, tyres, or the battery.

• Tyres: Punctures and general wear and tear are just as prevalent in EVs as in ICE cars. Due to the instant torque and often heavier weight of EVs, tyres can sometimes wear out quicker.
• Brakes: While EVs use regenerative braking, which reduces wear on physical brake pads, they still have a conventional braking system that can suffer from issues or require maintenance over time.
• Suspension Systems: Supporting the vehicle's weight and absorbing road impacts, suspension components can wear out.
• Windscreen Wipers & Bulbs: These are standard consumables that will eventually need replacing.
• Actuators & Other Ancillary Components: Items like power window motors, central locking actuators, and even comfort features such as heated seats, air conditioning/heating, and infotainment systems can sometimes fail, leading to inconvenience rather than a complete breakdown.

Battery Issues: The Heart of the EV

Electric vehicles typically come equipped with two types of batteries, each serving a distinct purpose and presenting different potential breakdown risks:

1. The 12V Battery: Often overlooked, this smaller battery powers the car's low-current systems, including critical safety systems (airbags, seatbelt pretensioners), infotainment, lights, and the vehicle's starting sequence. If this battery runs flat, you may find yourself stranded, unable to start the car or operate essential functions. EVs generally use Absorbent Glass Mat (AGM) batteries for their 12V systems, which typically last 3-4 years. However, their lifespan can be reduced by heavy usage or, paradoxically, by infrequent driving, which can lead to it ageing quicker and potentially causing an electric car breakdown.

2. The Main Lithium-Ion Battery: This high-voltage battery is the powerhouse, supplying energy to the electric motor, the AC compressor, cabin heating, and battery coolant heater. Running out of power from this main battery is a key breakdown risk for EV owners, often referred to as 'range anxiety'. While drivers are becoming more adept at managing their vehicle's range, the expansion of company EV fleets and car-sharing schemes could lead to instances where drivers forget to charge, increasing breakdown occurrences due to lack of power.

How Long Will an EV Battery Last?

EV lithium-ion batteries are designed for longevity, often lasting up to 10 years or more with careful use. However, it's important to note that over this period, capacity will naturally reduce, potentially by as much as 30%, which will, in turn, reduce the vehicle's range. Most manufacturers offer substantial warranties on their main batteries. For instance, Tesla provides an 8-year or 100,000-mile Battery and Drive Unit Warranty, whichever comes first. Replacing an out-of-warranty lithium-ion battery can be expensive, though cashback schemes for old batteries can partially offset this cost. Some EVs, like the Renault Zoe, offer battery leasing options, removing the financial burden of future battery replacement from the owner.

Software Problems

In our increasingly connected world, even cars are susceptible to software glitches. Some EV problems are software-related, but fortunately, these can often be fixed remotely by the manufacturer through over-the-air updates, much like updating your smartphone.

What to Do When Your Electric Car Breaks Down

Breaking down in an electric car requires much the same immediate response as in a petrol or diesel vehicle. Your safety is paramount.

• Prioritise Safety: As soon as you recognise a problem, try to pull over safely to the hard shoulder or the nearest safe area away from moving traffic.
• Activate Hazards: Turn on your hazard warning lights immediately to alert other drivers to your presence.
• Warning Triangle: If safe to do so, place a warning triangle a suitable distance behind your vehicle.
• Contact Breakdown Cover: Once you are in a safe location, contact your breakdown cover provider. Ensure you have breakdown cover that specifically caters for electric vehicles. Many providers, like Start Rescue, offer EV breakdown cover at no extra cost, with recovery operators trained in handling electric vehicle specific issues.

Running Out of Charge: The EV-Specific Breakdown

The fear of running out of battery, commonly known as 'range anxiety', is a very real concern for EV owners. While cars provide ample warnings, sometimes drivers don't pull over, or a suitable charger isn't available. Here’s what happens and what you can do:

Warning Signs of Low Battery

Most EVs provide real-time information about battery charge, making it easy to monitor:

• Dashboard Display: A battery charge gauge or percentage indicator provides a visual representation of remaining charge.
• Range Estimation Display: This calculates the approximate distance you can still travel based on remaining charge and driving habits.
• Warning Alerts: As the battery level drops, your EV will display messages, sound alarms, or both. It may enter a reduced power mode to conserve energy.
• Smartphone Apps: Many EVs connect to smartphone apps, allowing remote monitoring of battery status and range.

What Happens When Your EV Runs Out of Battery?

As the battery depletes, the car's functionality becomes limited. Non-essential systems like heating, air conditioning, and infotainment may stop or reduce power to save energy. Eventually, power to the electric motor will cease, causing the car to gradually lose speed and come to a complete stop. This loss of power can be sudden or progressive, depending on the vehicle’s energy management system.

Your Options When Stranded with a Flat Battery

1. Find a Nearby Charging Station: Use your in-car navigation, smartphone, or dedicated EV charging app (e.g., Zap-Map, Pod Point, BP Pulse, Charge Your Car) to locate the nearest charging point.
2. Use a Portable EV Charger: If you own one, a portable charger can provide a slow, emergency charge from a standard electrical outlet, giving you enough juice to reach a charging station.
3. Call Your Breakdown Cover Provider: Many EV breakdown providers offer mobile charging units that can provide a temporary power boost. If charging isn't feasible, they should be able to tow you to the nearest charging station.

How Far Can an EV Go on a Low Battery?

An electric car might travel for around 10-40 miles on a critically low battery (e.g., 10% or less). This varies significantly by EV model, battery size, health, and driving speed. It’s crucial not to rely on this; keep your EV charged above 20% when possible.

Motorway Breakdown Protocol

If your EV runs out of battery on a motorway, stay calm. Pull over safely onto the hard shoulder, turn on hazard lights, and place a warning triangle. Contact your EV breakdown cover provider immediately. Some vehicles have built-in assistance services; check your documentation.

Towing an Electric Car: A Crucial Difference

Towing an electric car is not the same as towing a petrol or diesel vehicle and requires specific care. EVs often lack a conventional neutral gear that fully disconnects the wheels from the motor. Towing with the wheels on the ground can cause the electric motor to spin and generate electricity, potentially causing serious and expensive damage to the motor and other electrical systems, especially if the car is in 'park' or the electric parking brake is engaged.

Therefore, any tow in the event of an EV breakdown should ideally be carried out by a flatbed truck or a recovery vehicle that can lift all four wheels off the ground. Manufacturers like Nissan (e.g., the Leaf) and Tesla explicitly state in their manuals that damage caused by improper towing (e.g., with wheels on the ground) is not covered by warranty. Reputable breakdown services that handle EVs are specifically trained to ensure the correct processes are followed for safe recovery.

Can You Push an EV If It Breaks Down?

Similar to towing, pushing an EV if it breaks down also risks damaging the electric motor. The wheels of an EV are directly linked to the electric motor, even if the car is in what appears to be a 'neutral' setting. Avoid pushing your EV if it breaks down.

Roadside Assistance and Charging Capabilities

The demand for electric car breakdown cover is growing as more people switch from ICE vehicles. Most major UK breakdown cover providers now offer mobile charging services for EVs. For instance, the RAC offers a '10-mile boost' through their EV Boost mobile charger equipped in patrol vans, often negating the need for a tow to a charging point for minor range issues. If a tow is necessary, they will arrange it appropriately, ensuring all four wheels are lifted.

Are Electric Cars Safe in a Crash?

Electric cars are designed to be just as safe, if not safer, in a crash than conventional petrol or diesel cars. Independent vehicle safety bodies like the European New Car Assessment Programme (Euro NCAP) conduct rigorous crash-testing. The vast majority of electric and hybrid cars currently on sale have received the top, five-star safety rating from Euro NCAP, indicating excellent performance in crash protection and robust crash avoidance technology. In the event of an accident, if the battery is simply flat, it should be fine. If an accident has occurred, the situation should be treated with the same caution as any vehicle, monitoring for potential fire risks, whether from batteries or an internal combustion engine.
