Can I get a full refund if my car develops a fault immediately?

If a car develops a fault within the first 30 days of purchase, you have a statutory 'Short-term Right to Reject'. This entitles you to a full refund from the dealer without the need to allow any repair attempts. After 30 days, you must give the dealer one opportunity to fix the issue.

Can I return a car for a refund after one failed repair?

Under the Consumer Rights Act 2015, if a dealer's single attempt to repair a vehicle is unsuccessful, or if further faults emerge, you can exercise your 'Final Right to Reject' to return the car for a refund.

Will I get 100% of my money back if I reject a car after 30 days?

While you are entitled to a refund after a failed repair, the dealer is permitted to make a deduction for 'fair use'. This is typically calculated based on the mileage you have added to the vehicle since the date of delivery.

Who has to prove a car is faulty under the Consumer Rights Act 2015?

For the first six months after purchase, the law assumes any fault was present at the time of sale. The burden of proof lies with the dealer to show the car was not faulty; after six months, the responsibility shifts to the consumer.

What happens to my PCP or HP finance if I reject a faulty car?

If you reject a car held on a Personal Contract Purchase (PCP) or Hire Purchase (HP) agreement, your contract is with the finance provider, not just the dealer. Once a rejection is accepted under the CRA 2015, the finance agreement should be cancelled and your deposit/instalments refunded, minus any usage deductions.

What can I do if a dealer refuses a refund for a faulty vehicle?

If a dealer refuses to honour your right to a refund after a failed repair, you can escalate the dispute to the Motor Ombudsman, or use Alternative Dispute Resolution (ADL). As a final resort, you may need to pursue a claim through the County Court (Small Claims Court).

CRA 2015: Can You Get a Full Refund After a Failed Repair in 2026?

The Consumer Rights Act 2015 (CRA 2015) remains the cornerstone of vehicle purchasing protection in the UK. As we move through 2026, the complexity of modern vehicles—with integrated AI, advanced ADAS systems, and EV battery management—often leads to a frustrating scenario: you take a faulty car back for repair, only for the issue to persist.

The short answer is yes, you can often get a full (or near-full) refund if a repair fails, but the rules change depending on how long you have owned the vehicle. Under the CRA 2015, you are not required to give a dealer endless opportunities to fix the same fault.

Your Statutory Buyer Rights

When you buy a car from a trader, the law dictates that the vehicle must be of satisfactory quality, fit for purpose, and as described. If it fails these standards, you have three primary windows of protection:

1. The Short-term Right to Reject (0–30 Days)

If a fault develops within the first 30 days of purchase, you have the "Short-term Right to Reject." You are entitled to a full refund without the dealer being allowed to attempt a repair first. You simply need to prove the fault existed (or was developing) at the point of sale.

2. The Right to Repair or Replacement (30 Days – 6 Months)

Once the first 30 days have passed, you must give the dealer one opportunity to repair or replace the vehicle. Under the CRA 2015, if that single repair attempt is unsuccessful, or if a new fault develops, you move to the "Final Right to Reject."

3. The Final Right to Reject (Post-Failed Repair)

If the dealer fails to fix the car after one attempt, or if they cannot perform the repair within a reasonable time or without significant inconvenience to you, you can trigger a "Final Right to Reject." At this stage:

You are entitled to a refund.
The dealer can make a deduction for "use." In 2026, this is usually calculated based on the mileage you have covered since purchase.
The burden of proof is on the dealer for the first six months to show the car wasn't faulty when sold.

Dealer and Trader Obligations

Under the CRA 2015 and the Consumer Protection from Unfair Trading Regulations 2008 (CPRs), car dealers carry heavy legal responsibilities.

The "One Opportunity" Rule

A common misconception is that a dealer can keep trying to fix a car until they get it right. Legally, after 30 days, they get one shot. If the car comes back from the workshop and the engine light flickers on again for the same issue—or a different one—the dealer is obligated to process a rejection if the consumer requests it.

Transparency and Disclosures

Under the CPRs 2008, dealers must not omit "material information." If a car was a Category S insurance write-off or had a history of intermittent electrical failures, failing to disclose this is a breach of the regulations and may give the buyer grounds to unwind the contract entirely.

The "Reverse Burden of Proof"

For any fault that occurs within the first six months, the law assumes the fault was present at the time of delivery. The dealer cannot simply say "it was fine when it left the forecourt." They must prove it was not faulty, which is a high legal bar to clear.

Dealing with Finance (CCA 1974)

In 2026, most cars are bought on PCP or HP. If you are financing the car, the Consumer Credit Act 1974 (CCA 1974) provides additional protection. Under Section 75, the credit provider is "jointly and severally liable" for any breach of contract. Furthermore, if you wish to exit the agreement due to a faulty car, you must notify the finance company, as they are technically the legal owners of the vehicle, not the dealer.

Failed Repairs in the Age of EVs and AI

By 2026, many "repairs" are software-based. It is important to note that a failed "Over-the-Air" (OTA) update that fails to rectify a hardware-induced fault still counts as a failed repair attempt. If a dealer claims they have "reflashed the ECU" and the car still malfunctions, your right to a refund remains intact.

Key Takeaways for 2026

One Chance: Dealers only get one attempt at a repair after the 30-day mark.
Deductions for Use: If you reject a car after 30 days, expect a fair deduction for the miles you have driven.
Evidence is King: Keep all work orders, diagnostic reports, and timestamps of when the fault occurred.
Finance Leverage: Always involve your finance company early; they often have more "clout" with the dealership than an individual buyer.
No "Admin Fees": A dealer cannot charge you an "admin fee" to process a legal rejection under the CRA 2015.

Steps to Take if a Repair Fails

Stop Driving: Continued use of the vehicle can be seen as "affirming" the contract.
Formal Notice: Write to the dealer (and finance company) stating you are exercising your "Final Right to Reject" under the Consumer Rights Act 2015.
Request a Timeline: Demand a refund within 14 days.
Ombudsman/Legal: If they refuse, the Financial Ombudsman Service (for financed cars) or Alternative Dispute Resolution (ADR) are your next steps.
