Common EV Issues to Check Before Buying

Buying an electric vehicle (EV) isn’t just a purchase — it’s a lifestyle shift. Whether you’re going green for environmental reasons or drawn to the thrill of instant torque, EVs offer a modern driving experience unlike anything else. But here’s the catch: not all electric cars are created equal, especially if you’re buying used.

Just like traditional cars, EVs come with their own set of quirks and potential pitfalls. But since they’re packed with software, batteries, and cutting-edge tech, the issues are often less visible to the untrained eye.

This guide walks you through the essential EV pre-purchase inspection, helps you recognise common used EV problems, and offers an electric car checklist that puts you in control. Think of it as your smart friend who’s been there, done that — and is happy to help you avoid buying a lemon.

Why EVs Need a Different Inspection Approach

EVs don’t have spark plugs, fuel filters, or exhausts to worry about. Sounds simpler, right? Well, yes and no.

Key differences in EV diagnostics:

• Battery condition is paramount — it’s like checking the engine in a petrol car.
• Software matters more than ever — features, range, and even safety can hinge on updates.
• Charging history and habits — how the car was charged affects its longevity.

Because electric cars wear differently than combustion vehicles, you’ll want to approach inspections with a fresh mindset.

The Ultimate EV Pre-Purchase Inspection Checklist

Let’s break it down step-by-step — here’s what you need to look for before committing to that shiny electric ride.

1. Battery Health and Performance

This is the most critical component.

• Check the battery’s State of Health (SoH): SoH measures how much capacity the battery retains compared to when it was new. A good figure is above 85% for a car under 5 years old.
• Ask for a battery health report: Some manufacturers offer diagnostics via the infotainment system or companion app. Otherwise, specialist garages can run a scan.
• Watch for uneven degradation: Signs of quick capacity loss might indicate excessive fast charging or poor thermal management.

Pro Tip: Avoid cars that have been constantly DC fast-charged — it’s convenient but can age the battery faster.

2. Charging History and Port Condition

A healthy EV has a healthy charging history.

• Inspect the charging port: Look for rust, broken pins, or wear-and-tear around the edges.
• Ask about typical charging habits: Was it home-charged slowly overnight? Good. Hammered daily with 150kW fast-charging? Potential red flag.
• Verify charging compatibility: Is the car CCS, CHAdeMO, or Type 2? Make sure it fits your local charging infrastructure.

3. Driving Range in the Real World

Forget the glossy brochure figures — what’s the real range?

• Compare displayed range with online reviews: For example, if a 2018 Nissan Leaf shows 110 miles instead of 150, that might be normal — but it’s crucial to know what’s standard.
• Test the range under your usual driving conditions: If possible, take a long test drive involving city traffic, hills, and motorway cruising. Range can swing drastically based on driving style.

Relatable Scenario: Ben from Manchester bought a used EV claiming 160 miles of range. But with his 40-mile daily commute at 70mph and winter temps, it barely made 120. Lesson? Always verify under your real-life use.

4. Software & Infotainment System

The heart and brain of most modern EVs.

• Check the firmware version and update history: Some cars, like Teslas, improve with over-the-air updates. Others fall behind if not updated manually.
• Test touchscreen responsiveness: Laggy infotainment isn’t just annoying — it can make vital functions like climate control a nightmare.
• Ensure all driver assist features work: Lane-keep assist, adaptive cruise, regen braking — test them on a drive.

5. Climate System and Battery Cooling

Battery temperature matters — more than you’d think.

• Run the heater and AC at full blast: EVs with heat pumps are more efficient. If cabin heat takes ages to come on, it could hint at HVAC or battery heater issues.
• Ask whether the battery is actively cooled: Older models (like the 24kWh Leaf) use passive air cooling, which can lead to quicker degradation in warmer climates.

6. Warning Lights and System Alerts

Don’t ignore those little dashboard icons.

• Plug in an OBD-II scanner: It can detect hidden faults not showing on-screen — invaluable for spotting issues with the battery or motor.
• Look for repeated warnings or resets: Recurring faults are a deal-breaker unless fully documented and fixed.

7. Tyres, Suspension, and Undercarriage

EVs are heavier due to battery packs — tyres and suspension wear faster.

• Inspect for uneven tyre wear: May indicate suspension issues or poor alignment.
• Check under the car for scrapes or damage: Especially in older EVs with low ground clearance.
• Listen for clunks or knocks over bumps: Worn bushings or shocks are common in heavier, ageing electric cars.

8. Service Records and Warranty Status

Trust is built on paper.

• Request full service history: Was it dealer-serviced on schedule? Has the battery been checked recently?
• Understand the battery warranty: Most manufacturers offer 8-year or 100,000-mile battery warranties. Some allow transfers to second owners.
• Check for recalls: A quick VIN check can tell you if the vehicle had any safety-related recalls — and whether they were resolved.

9. EV Test Drive Essentials

Don’t just test drive — stress test.

• Start-stop traffic: Try regen braking and low-speed manoeuvring.
• Motorway speeds: Listen for noise, check stability.
• Steering feedback: Does it feel natural or overly assisted?
• Acceleration and one-pedal driving: Are they smooth and responsive?

Common Used EV Problems to Watch Out For

Even the best EVs aren’t immune to issues. Here are some known gremlins across the market:

Note: This isn’t to scare you off — just to empower you with foresight.

Case Study: John’s EV Regret Turned Win

John, a retiree in Leeds, bought a used Renault Zoe with low mileage and a tempting price tag. But within a month, he noticed sluggish charging and found out the heat pump had failed — something the previous seller didn’t disclose.

Thankfully, the car was still under manufacturer warranty. Repairs were covered, but the stress left him cautious.

His advice? “Get a battery health report and insist on a long test drive. Ask awkward questions. It’s your money, after all.”

A Smart Inspection Makes for a Smoother Drive

Buying a used EV is a brilliant move — for your wallet, the planet, and your peace of mind. But it pays to do your homework. The EV pre-purchase inspection isn’t just about checking off boxes — it’s about understanding how the car was treated, how it performs today, and how it will serve you tomorrow.

By paying attention to battery health, charging habits, software stability, and the used EV problems outlined here, you’ll be equipped to make a decision that’s driven by confidence, not guesswork.
