Overview

Mercedes-Benz has been accused of emissions cheating. Lawyers believe the company fitted thousands of its diesel vehicles with so-called “defeat devices”. These devices cheated emissions tests to make vehicles appear more environmentally friendly than they were.

People who bought or leased the affected Mercedes cars and vans were misled about their efficiency and environmental friendliness. They may have suffered inflated fuel and maintenance costs, and the affected vehicles are likely to be worth less than the drivers paid for them.

The High Court has ruled against Mercedes-Benz, opening the way for claims against the company in the UK. A trail will begin in Autumn 2025.

If you purchased, leased or financed an affected Mercedes vehicle you could have a no-win, no-fee compensation claim. Sign up as soon as possible so you don’t miss the deadline.

Mercedes emissions FAQs

Mercedes faces legal action for allegedly fitting several of its diesel models with emissions-reducing software. As well as the potential impact on the environment and human health, this scandal resulted in significant financial losses to owners of these vehicles. Drivers of affected Mercedes vehicles may have experienced higher fuel bills and maintenance costs than was promised. The cars are likely to be worth less than drivers paid for them. We believe these drivers deserve compensation for the possible harm and injustice experienced

The affected Mercedes vehicles were first registered between 2008 and 2018. However, the wider ‘dieselgate’ scandal involves many more car manufacturers.

Named ‘dieselgate,’ numerous diesel cars and vans are entangled in this environmental scandal, and yours might be among them.

Volkswagen (VW) has already agreed to a £193 million settlement for affected vehicles, setting a precedent that your vehicle manufacturer could soon follow. The list of implicated vehicle manufacturers is extensive. These vehicles were deceptively marketed as environmentally friendly, boasting lower nitrogen oxide (NOx) emissions. However, the reality was quite the opposite.

Defeat devices artificially lowered emissions during testing to meet EU regulations. However, when these same vehicles were driven on the road, they proved to emit significantly higher levels of nitrogen oxide (NOx) gases compared to the reported test conditions. This not only posed a threat to the environment but also jeopardised public health.

Lawyers are actively investigating these claims on behalf of individuals, just like you, who have owned or leased one of the affected diesel vehicles. The potential compensation for this claim could be substantial, likely amounting to thousands of pounds. If you purchased or leased a diesel vehicle and suspect you may have been impacted, we strongly encourage you to join the claim today.

If you have owned or leased an affected diesel vehicle first registered between 2008 and 2018, you could have a NO-WIN, NO- FEE compensation claim. Our simple eligibility checker provides instant clarity. Answer a few straightforward questions, and you’ll know if you qualify for a Mercedes emissions group action claim.

Yes. If you bought a used diesel car you may still be eligible for compensation. Try our simple eligibility checker to see if you have a claim.

Yes, if you sold an affected vehicle, you may still be able to join a group action. Try our simple eligibility checker to see if you have a claim.

We cannot say how much compensation you might get if you win your case. Each claim is based on its merits and your solicitor will work to get the money owed to you. Affected drivers could get several thousands of pounds if their claim is successful. In this case, we believe drivers could get up to £10,00 in compensation.

In the UK, if a group of people have experienced loss, or otherwise been harmed by an organisation’s law breaking, they can come together to fight for justice. Levelling the playing field when standing up to big businesses, group actions prove there is strength in numbers. At Join the Claim, we bring consumers and law firms together to ensure these group actions are as powerful as possible.

We won’t charge you a single penny to check your eligibility. And we ensure any law firms we connect you with operate on a no-win-no-fee basis.
