EV range not as advertised? Here’s what to do

Electric vehicles (EVs) are often sold on the promise of impressive driving ranges, but many drivers are finding that real-world performance doesn’t always match what was advertised.

If your EV isn’t delivering the mileage you were promised, you may have grounds to complain. Here’s what you need to know, and what you can do next.

Why your EV range might be lower than advertised

Manufacturers typically quote range based on standardised lab tests (such as WLTP), which don’t always reflect real driving conditions.

Common factors that reduce EV range include:

Cold weather (can significantly impact battery efficiency)
High-speed motorway driving
Frequent short trips
Use of heating or air conditioning
Battery age or degradation

A small difference is normal, but if the gap is significant, it could be a problem.

When it becomes a valid complaint

You may have a case if:

The range is consistently far below the advertised figure (not just occasionally)
The salesperson or advert misled you about real-world performance
The vehicle has a faulty battery or system
You were promised a specific range in writing or verbally

Under the Consumer Rights Act 2015, your car must be:

As described
Of satisfactory quality
Fit for purpose

If it isn’t, you may be entitled to a repair, replacement, or refund.

Step 1: Gather evidence

Before making a complaint, collect:

Screenshots/photos of your actual range and usage
The advertised range (from brochure, website, or contract)
Details of driving conditions
Any communication from the dealer about expected performance

This helps show that the issue is ongoing, not just a one off.

Step 2: Check for faults

Sometimes reduced range is caused by a fault, such as:

Battery issues
Software problems
Charging faults

Contact the dealer or manufacturer and ask for:

A diagnostic check
A written report of findings

If a fault is found, it should usually be repaired under warranty.

Step 3: Complain to the seller

Your contract is with the dealer, not the manufacturer.

When you contact them:

Clearly explain the issue
Provide your evidence
State what outcome you want (repair, refund, or compensation)

Be specific, for example:

“The vehicle consistently achieves 180 miles, significantly below the advertised 280 miles. I believe this is not as described under the Consumer Rights Act 2015.”

Know your rights based on timing

Your options depend on how long you’ve had the car:

Within 30 days

You may be entitled to a full refund (short-term right to reject).

Within 6 months

The fault is presumed to have been present at purchase.
You can request:

Repair or replacement
Refund if that fails

After 6 months

You may still claim, but you’ll need to prove the issue existed when you bought it.

What about “normal variation”?

Dealers may argue that range differences are expected, and they’re partly right.

However, you may still have a claim if:

The difference is significant (e.g. 20–30% or more)
Marketing gave a misleading impression of real-world use
You were advised it would suit a specific need (e.g. long commute) and it doesn’t

Step 4: Escalate if needed

If the dealer refuses to help:

Resolver can help you manage and escalate your case
Contact the Motor Ombudsman (if the dealer is a member)
Consider a Section 75 claim (if paid by credit card)
As a last resort, take the case to small claims court

How to avoid EV range issues in future

Before buying an EV:

Look for independent real-world range tests
Ask about winter performance
Check owner reviews and forums
Get any promises about range in writing

EV range figures are often optimistic, but they shouldn’t be misleading. If your car is falling well short of what you were promised, you don’t have to accept it. With the right evidence and approach, you may be able to secure a repair, refund, or compensation.
