Consumer Protection: Transactions are governed by the Consumer Rights Act 2015. You have a statutory right to goods and services of satisfactory quality.

Buying a used car is a significant financial decision. If the vehicle turns out to be faulty or not as described, consumer law in England and Wales gives you rights to reject the car, obtain a refund, or seek other remedies in certain circumstances. This article explains your legal position under the Consumer Rights Act 2015, how to reject a faulty used car, the time limits that apply, practical steps for making a claim, and what to do if a dealer refuses your request. It also highlights key differences between buying from a dealer and a private seller, and what counts as a legitimate “fault” under the law, using up‑to‑date, authoritative information.

When You Can Reject a Faulty Used Car

Applicable Law: Consumer Rights Act 2015

If you bought a used car from a trader or dealer, the Consumer Rights Act 2015 applies. This legislation requires that goods sold by businesses - including used vehicles - must be:

  • Of satisfactory quality
  • Fit for purpose
  • As described

These criteria take into account the car's age, mileage, and price when assessing whether its condition meets acceptable standards.

Short‑Term Right to Reject (First 30 Days)

Under the Act, if the car is faulty or does not meet the above standards within 30 days of purchase, you have a short‑term right to reject the car and request a full refund. This is often called the 30‑day right to reject.

This right covers faults that were present when you bought the car or developed shortly after because of an underlying defect. Examples include:

  • Major engine or transmission failure
  • Electrical faults affecting drivability
  • Vehicle not roadworthy or failing MOT immediately after purchase
  • Misrepresentation of key features or service history

Minor issues such as small cosmetic marks that do not affect performance are unlikely to justify a full rejection.

Practical Steps to Reject a Faulty Car

1. Document the Faults Immediately

As soon as you notice a problem:

  • Take clear photos or videos of the fault.
  • Keep copies of the sales contract, listing information, MOT certificates, service history and any warranties.

Detailed evidence strengthens your position if there is a dispute.

2. Notify the Dealer in Writing

Write to the dealer or trader promptly, clearly stating:

  • You have discovered a fault.
  • You are exercising your statutory right to reject the car under the Consumer Rights Act 2015.
  • You expect a full refund and details about returning the vehicle.

Keep proof of delivery for any letters. A clear written record helps if the matter escalates.

3. Return the Car

You should arrange to return the vehicle to the dealer once you have notified them. Ensure you do so in a way that documents the handover (for example, with signed collection notes or photographic evidence).

What Happens After You Reject the Car

Within 30 Days

If the dealer agrees the vehicle is faulty and eligible for rejection:

  • You should receive a full refund, which usually must be paid within 14 days of the dealer accepting your rejection.

After 30 Days But Within Six Months

Once the 30‑day period has passed, your rights change:

  • The dealer gets one opportunity to repair or replace the car.
  • If they cannot fix the fault, you may be entitled to a refund or price reduction, but the dealer may deduct an amount for your use of the car.

Statutory rules presume faults appearing within six months were present at the time of sale unless the dealer can prove otherwise.

Buying From a Private Seller

If you purchased the car from a private individual, statutory consumer rights under the 2015 Act generally do not apply, whether new or used. Your rights will instead arise from the contract you made with the seller under ordinary contract law, which is usually more limited. For example, you may only have a remedy if the seller misrepresented the car's condition or breached a term of your agreement.

In contrast, when buying from a dealer, statutory provisions protect you regardless of what sales paperwork says. Terms like “sold as seen” do not override these legal rights.

Remedies and Practical Considerations

Full Refund

If you reject a faulty car within the first 30 days and the fault meets statutory criteria, you are entitled to a full refund, including any deposit or payments you made.

Repair or Replacement

If the car fails after 30 days but before six months, the dealer can attempt one repair or one replacement. If this fails, you can seek a refund or price reduction, but deductions for mileage and use are likely.

“Fit for Purpose” and “As Described”

If the car was sold for a specific purpose you made clear at the time (for example, a daily commuter) and it fails in that role due to a defect, this may increase your chances of a successful rejection claim. Similarly, if the vehicle does not match the advertised description (for example, omitted features or untrue service history), this can support your claim.

What to Do if the Dealer Refuses

If the dealer refuses to accept the rejection or disputes that the car is faulty:

Engage Third Parties

  • Citizens Advice can help you understand your rights and next steps.
  • Trading Standards can investigate unfair trading practices.

If informal resolution fails:

  • You may take the matter to the small claims court (County Court) for recovery of your money. This is often the next step when a dealer will not co‑operate.

Common Questions

Can You Reject a Car After 30 Days?

Yes, but only if the dealer has first had a reasonable opportunity to repair or replace it. If that fails, you may seek a refund or price reduction rather than an outright rejection.

Do You Have to Accept a Dealer's Warranty?

No. Dealer warranties are additional to your legal rights, not instead of them. You can still reject, seek a repair, or pursue a refund through statutory rights, even if a warranty exists.

Does Payment Method Matter?

If you paid via credit card with a deposit of at least £100, you may also have rights under Section 75 of the Consumer Credit Act 1974 against the finance provider, offering another avenue for reclaiming funds.

Key Takeaways

When buying a used car from a dealer in England and Wales, the Consumer Rights Act 2015 provides strong protections:

  • You have a 30‑day right to reject a faulty car and obtain a full refund.
  • After 30 days up to six months, you can still seek repairs, replacements or refunds if faults persist, albeit with possible deductions for use.
  • Buying from a private individual offers fewer protections, and your rights will depend on contract terms rather than statutory safeguards.
  • Clear documentation, prompt notification to the dealer, and keeping detailed records are essential to asserting your rights effectively.

Understanding and exercising your rights can help you secure a fair outcome if a used car turns out to be faulty.
