What have Mercedes-Benz done?

The German Federal Motor Transport Authority (KBA) found that Mercedes installed a cheating software in their diesel engines that limited emissions readings during vehicle emissions testing and therefore misrepresenting the actual emissions during real-world driving meaning they didn’t comply with EU regulatory requirements.

The KBA has now ordered Mercedes to recall around 90,000 vehicles in England and Wales, with the manufacturer having also recalled hundreds of thousands more vehicles on a voluntary basis. Despite this finding, Mercedes deny they have done anything unlawful.

Why choose Slater and Gordon for your Mercedes-Benz diesel claim?

Slater and Gordon are leading experts in Collective Actions and emissions claims. We were appointed joint Lead Lawyers on the Volkswagen Emissions collective action where we successfully reached a significant financial settlement for our clients. We acted on behalf of over 71,000 of the 91,000 claims, which is thought to be the largest Collective Action in British legal history in terms of number of Claimants.

We want to provide you with the same opportunity to claim against Mercedes.

Why should I join the Mercedes-Benz claim?

We consider it to be unacceptable that customers have been sold vehicles which do not comply with emissions regulations.

In the Mercedes emissions claim, we’ll be arguing that affected vehicles produce levels of NOx that are higher than the law permits, when driven on the road. NOx is a combination of the pollutants Nitrogen Oxide and Nitrogen Dioxide and has been associated with, amongst other things acid rain, global warming, and respiratory conditions, such as childhood asthma. We believe manufacturers should adhere to the rules limiting the amount of pollution their vehicles emit. That’s why we’re suing Volkswagen, and that’s why we think Mercedes also have a case to answer.

During Cop26, Mercedes were among other manufacturers to have signed a pledge to only sell zero-emissions vehicles by 2035 in 'leading markets'. But what about the damage already caused by Mercedes when they installed emissions cheating devices into vehicles, which caused irreversible environmental damage?

We're standing with those who're refusing to turn a blind eye and are holding Mercedes accountable for their actions.

As well as the environmental and ethical reasons for holding Mercedes to account, there’s also the very real possibility that owners have overpaid for a vehicle which doesn’t comply with emissions regulations and that now needs to be fixed. It may also be the case that the fix itself has consequences to the fuel consumption and performance of your vehicle. If this is the case, we’ll bring a claim for those additional costs too.
