Nissan/Renault emissions FAQs

Find out more information on the Nissan/Renault emissions claim and how you can join the action.

What are the claims about?

Leigh Day is investigating a group action against Nissan and Renault over an alleged ‘defeat device’ fitted in some of their diesel cars in order to artificially reduce emissions to pass regulatory tests. We believe that the software used in the vehicles is unlawful under UK law and intend to bring legal claims for compensation on behalf of consumers who purchased affected vehicles.

If you bought or leased a diesel Nissan or Renault vehicle since 2009, you can apply to join the claim. Please complete our online vehicle registration checker below, to confirm if your vehicle is eligible.

Nissan/Renault emissions claim FAQs

The current claim against Nissan and Renault relates to diesel vehicles only.

Please complete our online vehicle registration checker to confirm if your vehicle is eligible to join the claim. Please note that the claims are still in the early investigation stage. It may be that following receipt of further evidence, we do not consider your particular vehicle to be affected by the emissions issue. If this is the case we will explain this to you fully.

These vehicles are not covered by the current sign up process. However, to register your interest in bringing a claim in relation to these models, please contact us directly on

Most likely yes, provided you are able to confirm that your ex-vehicle is eligible. You will need to check your vehicle registration number and we will ask you to provide us with your vehicle purchase documents.

It doesn’t matter. You are eligible to join the claim whether your vehicle was bought new or second hand.

Provided all the vehicles you want to claim for are eligible, yes. We will need you to complete a separate questionnaire for each of your vehicles.

No, it does not matter where you bought your Nissan/Renault vehicle as long as it was bought in England & Wales. You are eligible to bring a claim against the manufacturer whether you bought your vehicle from a showroom, from a private seller or from a third party dealer, or if you bought the car for business purposes.

Yes, provided you bought an eligible vehicle, you are able to bring a claim.

Yes, if the contract is in your name and the vehicle is eligible, you are able to bring a claim.

Yes, if the contract is in your name and the vehicle is eligible, you are able to bring a claim.

The claims are centred around the argument that, had the purchaser known about the emissions issue/ defective parts, then this would have been a significant factor in their decision to buy the vehicle or to continue to make payments under a finance agreement.

If knowledge of the emissions issue makes little or no difference to your decision to buy the vehicle, then you may not be able to claim. Please do contact us directly on if you would like to discuss your specific circumstances.

You do not need to have any documents to start your claim with Leigh Day.

At some stage we will ask you to provide us with documents regarding the purchase of your vehicle including for e.g. the contract of sale or other proof of purchase, finance agreement and/or lease agreement. If you have these documents, then please place them somewhere safe until we request them. Do not worry if you no longer have these documents, we will be in touch with details about how to request them.

If your vehicle is eligible we will offer to act for you on a “No Win-No Fee’ basis. This means that we’ll deduct up to 35% (inclusive of VAT) of your damages if the claim is successful. We provide two worked examples below to assist your understanding:

Awarded compensation: £7,500

After deductions, the minimum amount you will receive: £4,875

Awarded compensation: £2,500

After deductions, the minimum amount you will receive: £1,625

If the claim is unsuccessful you will not have to pay anything. Our Success Fee, the insurance premium and any funder’s fees will never be more than 35% of your damages, irrespective of the number of claimants within the group.

Once you have checked that you are eligible to bring a claim, we will ask you to read through our funding agreement and sign the same. You will then be a client of the firm.

If you lose (that is, you get no money back from the Defendants), then you do not have to pay us anything.

We will arrange insurance to protect you against the risk of losing and having to pay the Nissan/ Renault Group’s legal costs.

You may have alternative ways of funding your claim (other than the funding package we are offering). For example:

  • Legal expenses insurance. Many home insurance products include legal expenses insurance either automatically or as an optional add-on. You should contact your insurers to check.
  • If you are a member of a trade union, you should check whether the union will fund you.
  • If you have such an alternative source of funding, then it may be cheaper for you to use it than the funding package we are offering. We are not offering to act via such legal expenses insurance/union funding, so if you wish to use it you may need to instruct another firm.

At this early stage, it is impossible for us to give an accurate prediction of timescale. As with any legal claim, there are some things within our control and some things outside our control. Much will depend on the Defendants’ response to the legal claim.

In our experience group claims of this type may take 2 to 5 years to progress through the Court, but it could take longer. As a client you will be provided with regular updates, particularly in relation to the timescale for next steps which can be predicted more accurately than for the case as a whole.

This is the first time that these types of claims are being brought against Nissan and Renault in the English courts. Leigh Day is one of the country’s leading law firms and bringing group actions on behalf of consumers is one of our key areas of speciality. Leigh Day are joint-lead lawyers in a similar emissions litigation on behalf of Volkswagen owners and recently won the first round of the case against Volkswagen in the UK High Court.

The types of legal claims we would recommend you bring will depend on your individual circumstances (such as when you bought your vehicle, whether you bought it from an authorised dealer and whether it was paid for using finance). As such it is impossible to say that all claims will be worth a certain amount.

For those clients who are eligible to bring a claim under the Consumer Protection from Unfair Trading Regulations 2008 (“CPUT”) (those being people who bought their vehicle on or after 1 October 2014, via an approved dealer or using approved finance and for non-business use) are entitled to recover a discount on payments made ranging from 25% to 100%. The compensation recoverable under other types of claim is more dependent on proving loss and a lower amount may be recoverable than under CPUT.

Leigh Day is one of the country's leading law firms, we are not a claims management company. Bringing group actions on behalf of consumers is one of Leigh Day's key areas of specialty and we have been involved in some of the largest group actions ever taken in the UK.

We are joint-lead lawyers in the emissions litigation on behalf of UK Volkswagen owners, and recently won the first round of the case against Volkswagen in the UK High Court.

In that case we argued that Volkswagen had deceived car owners as to the compliance of vehicles with EU Emissions Regulations. Lawyers for the UK drivers argued that Volkswagen engines contained defeat device software which sensed when the vehicle was being tested and so artificially reduced emissions in order to pass that test.

Volkswagen has always argued that the software did not meet the legal definition of a defeat device and so was not illegal. However, in April 2020 the High Court in London found that the decision by the KBA, the German road vehicle authority, that the software was a ‘defeat device’ was binding in the English High Court. Volkswagen was recently refused permission to appeal the judgment.

Yes. Affected vehicles which were leased or purchased from Motability are eligible to join the claims. 

There are a number of possible legal claims a vehicle owner could pursue in relation to their vehicle. It may be that, as a result of how you leased your vehicle, we only advise you to pursue some types of legal claim, and not others. If you have your Motability documents, please keep these somewhere safe until we request a copy.

If we find on investigation that a vehicle isn’t affected, or for some other reason isn’t eligible to join the claim, we would contact you to inform you, and then cancel our legal agreement with you. You would not need to pay us any money for the work we had done in these circumstances.
