Buying a car is a big investment. When that car turns out to be faulty, it can feel like a nightmare. Faulty vehicles cause stress, unexpected costs, and sometimes safety risks. Knowing your legal options can help you take control and protect your rights. In this post, I will guide you through what to do if you find yourself with a faulty car in the UK. I will also share practical advice and examples to help you understand your choices clearly.

Understanding Your Rights Under the Consumer Rights Act 2015
When you buy a car from a dealer in the UK, the Consumer Rights Act 2015 protects you. This law says the car must be:
Of satisfactory quality
Fit for purpose
As described
If the car is faulty, you have the right to reject it, ask for a repair, or request a replacement. These rights apply for up to 30 days after purchase. This period is called the "short-term right to reject." If you act within this time, you can get a full refund.
After 30 days, you can still claim a repair or replacement. If the dealer cannot fix the problem, you may be entitled to a partial refund or final rejection. The law also covers used cars, but the expectations might be different depending on the car’s age and price.
Knowing these rights is the first step. Many people do not realise they can reject a faulty car or demand a repair. This knowledge gives you power when dealing with dealers or finance companies.
Steps to Take When You Discover a Faulty Car
If you notice a problem with your car, act quickly. Here are the steps I recommend:
Document the fault
Write down what is wrong and when you noticed it. Take photos or videos if possible. This evidence will help if you need to make a claim.
Contact the dealer
Tell the dealer about the fault in writing. Be clear and polite. Ask for a repair, replacement, or refund depending on your situation.
Keep records
Save all emails, letters, and receipts. Keep a log of phone calls with dates and times.
Get an independent inspection
If the dealer disputes the fault, an independent mechanic can provide a report. This can support your case.
Use dispute resolution services
If the dealer refuses to help, you can use services like the Motor Ombudsman or Trading Standards.
Taking these steps early can prevent problems from getting worse. It also shows you are serious about your rights.
Comparing Legal Support Services for Faulty Cars
When dealing with a faulty car, you might want professional help. Here are two services that can assist you:
CarRejection.com
This service specialises in helping UK car buyers reject faulty vehicles under the Consumer Rights Act 2015. They offer expert advice and support to resolve disputes with dealers and finance companies. Their website has useful guides and a team ready to assist. You can learn more at CarRejection.com.
The Motor Ombudsman
An independent body that handles complaints about cars and dealers. They offer free dispute resolution and can investigate your case. Their service is trusted and widely used in the UK. Visit The Motor Ombudsman for details.
Both services aim to protect your rights but work differently. CarRejection.com focuses on legal advice and direct support for rejecting faulty cars. The Motor Ombudsman offers a formal complaint process and mediation. Depending on your case, you might use one or both.
Using these services can save time and stress. They know the law and how to deal with dealers effectively.

What to Do If You Bought a Faulty Car on Finance
Many people buy cars using finance deals. This adds another layer to your rights and responsibilities. If your car is faulty and you have a finance agreement, you still have rights under the Consumer Rights Act 2015. You can reject the car or ask for a repair.
However, the finance company owns the car until you finish payments. This means you must inform them about the fault. They may pause payments while the issue is sorted. You should also notify the dealer and keep all communication clear.
If the dealer refuses to help, you can challenge the finance company to protect your interests. Some finance agreements include a "voluntary termination" clause, allowing you to return the car after paying half the total amount. This might be an option if the car is seriously faulty.
For example, a customer bought a car on finance and found a major engine fault within two weeks. They contacted the dealer and finance company. With help from CarRejection.com, they rejected the car and stopped payments. The finance company accepted the return, and the customer got a full refund.
Knowing your rights with finance can prevent you from paying for a car you cannot use.
How to Use the Consumer Rights Act to Reject a Faulty Car
Rejecting a faulty car means returning it to the dealer and getting your money back. To do this successfully, follow these tips:
Act within 30 days of purchase for a full refund.
Inform the dealer in writing about the fault and your intention to reject.
Keep the car in good condition and avoid using it unnecessarily.
Be clear and firm but polite in your communication.
If the dealer offers a repair, consider if it is reasonable before rejecting.
If the dealer refuses to accept the rejection, you can escalate the matter. Use dispute resolution services or seek legal advice. Many buyers find success by showing they know their rights and have evidence.
For example, a buyer noticed faulty brakes within a week. They emailed the dealer to reject the car. The dealer tried to fix the brakes, but the problem returned. The buyer then used CarRejection.com’s advice to reject the car formally and got a refund.
This shows the importance of acting quickly and knowing your legal options.

When Repairs and Replacements Are the Best Option
Sometimes rejecting a car is not the best or only choice. If the fault is minor or can be fixed quickly, a repair might be better. The dealer must repair the car within a reasonable time and without causing significant inconvenience.
If the repair fails, you can then ask for a replacement or reject the car. Replacement means the dealer gives you a similar car without faults. This option is less common but available under the law.
Choosing repair or replacement depends on:
The severity of the fault
How long the repair will take
Your personal needs and preferences
For example, a buyer had a faulty air conditioning system. The dealer repaired it within a few days. The buyer was happy with the fix and continued using the car. This saved time and avoided the hassle of rejection.
Knowing when to accept a repair or push for rejection is part of handling a faulty car wisely.
Tips for Avoiding Faulty Cars in the Future
While legal options help after buying a faulty car, prevention is better. Here are some tips to reduce the risk:
Buy from reputable dealers with good reviews.
Ask for a full service history and check MOT records.
Get an independent inspection before buying.
Avoid cars with unclear ownership or accident history.
Understand the terms of any finance agreement.
Using services like CarRejection.com’s guides can help you spot warning signs. Being cautious and informed saves money and stress.
