About the Claim

We believe Jaguar Land Rover has sold cars with defective components, including diesel particulate filter (DPF) systems, and consumers are entitled to thousands in compensation

Jaguar Land Rover is one of Britain’s most famous car manufacturers, but its cars are also among the most unreliable. What Car?’s 2022 reliability survey placed Land Rover at the bottom of the table – number 31 out of 32.

We are bringing a new group action seeks over £3bn on behalf of Jaguar Land Rover customers who purchased cars with defective components, including diesel particulate filter (DPF) systems. Over 500,000 new car owners may be eligible to make a claim, and hundreds of thousands of additional pre-owned car owners may also have claims.

If the case is successful, claimants could receive between £3,000 and £16,000 each in compensation.

What have Jaguar Land Rover done wrong?

Jaguar Land Rover has been happy to sell  cars with defective components, including diesel particulate filter (DPF) systems, without disclosing the challenges drivers will meet.

Our investigations reveal the vehicles are defective in their design and can cause significant on road safety and performance issues for drivers. The defects also cause accelerated engine wear forcing customers to pay additional costs for servicing, including in some cases engine replacement.

This is a new problem, separate to the dieselgate scandal.

Jaguar Land Rover uses a DPF system to reduce emissions from their cars. The DPF system forms an essential part of the diesel aftertreatment system.

A DPF system collects combustion particulates in the filter which are then burned off when the engine reaches a high temperature, in a process called regeneration. When functioning properly, the DPF system should be self-cleaning and remove the soot build up.

We say that the DPF systems installed by Jaguar Land Rover were not fit for purpose.

What is the harm to drivers?

The claim alleges certain Jaguar Land Rover cars suffer from core defects which mean, among other things, the system is not effective in regenerating the DPF. This results in poor performance, expense to owners, damage to the engine and risks to road user safety.

In short, people have been paying up to £120,000 for cars that were not fit for purpose.

Drivers were sold a combination of driving performance and reliability, but Jaguar Land Rover failed to deliver – see below for more detail:

Limp mode

A full or clogged DPF can cause the car to enter “limp mode”, making it slower and less responsive, increasing the risk of an accident and putting both the owner and other road users in danger.

Shortened service intervals

The defective components means the affected cars need to be serviced more frequently than would have been expected when they were purchased, with the associated costs being met by the car owners. 

Engine damage

Driving with a full DPF filter and other defects can also cause damage to the car leading to oil dilution and increased wear and tear of the engine. The defects can also result in the vehicle needing more frequent oil changes.

Higher costs

Costs of additional servicing, increased fuel consumption and maintaining the defects are often passed onto the drivers. In some cases, drivers are advised to replace the DPF system entirely and at their own expense.

Are you eligible?

If you purchased, financed, leased or owned a Jaguar Land Rover diesel vehicle (new or used) from January 2015 onwards, you may be eligible for compensation.
