Claim against Stellantis over emissions-cheating campers nears court
Consumer organisations say legal action will follow if Stellantis refuses to discuss a settlement for motorhome owners.

Stichting Car Claim, the Consumentenbond and the Nederlandse Kampeerauto Club are preparing a collective case against Stellantis over diesel engines in motorhomes. Public sources confirm that the final step before legal action was taken in July, but do not show that the case has since been formally filed.
The claim concerns motorhomes with Euro 5 and Euro 6 diesel engines from Fiat, a brand owned by Stellantis. Many motorhomes are built on a Fiat Ducato chassis. According to the Consumentenbond and the NKC, these engines used software that made emissions controls less active under certain conditions than during an emissions test.
The organisations want Stellantis to repair the motorhomes and financially compensate affected owners. They argue that consumers bought a vehicle that did not meet statutory emissions requirements and was therefore worth less. According to the public information, the claim concerns motorhomes marketed from 2009 to 2019, although some examples may have been sold to Dutch consumers later.
On 13 July, the Consumentenbond reported that Car Claim had sent the final letters to Stellantis. The manufacturer was invited to enter discussions. If that produced no solution, legal action would follow. The current public claim page records no judgment on the motorhomes and does not make clear whether a summons has since been issued.
There is a separate Dutch proceeding concerning Stellantis diesel cars. In 2025, the court ruled that certain Opel, Peugeot, Citroën and DS models contained prohibited defeat devices. Stellantis disputed the ruling and said the vehicles complied with all regulations. That judgment does not automatically apply to the motorhomes, but according to the claim organisations it provides important legal context.
Stellantis refers to the motorhome issue in its half-year report as a possible collective claim by Dutch consumers concerning emissions compliance in former FCA vehicles sold as recreational vehicles. The company writes that the outcome of such proceedings cannot be predicted and that damages could affect its financial position and reputation.
For motorhome owners, the proceedings are not without risk. According to the Consumentenbond, consumers can participate on a no-win, no-fee basis, with up to 25 per cent of any compensation being withheld. Until a court has ruled on the motorhome engines, however, it is not established exactly which vehicles are covered by the claim, who is liable or what compensation might be available.
One story, several perspectives
What is established
- Consumer organisations are preparing a collective claim.
- An earlier ruling concerning Stellantis diesel cars did not automatically apply to motorhomes.
- Stellantis itself mentions a possible Dutch motorhome claim.
Left
Arguments Large manufacturers must take responsibility for environmental harm and actively compensate consumers who drove defective vehicles for years.
Values Consumer protection, public health and corporate responsibility.
Consequences A broad settlement could help affected people quickly, but could also entail high costs and create a precedent for the sector.
Centre
Arguments Independent experts and the court should establish, for each vehicle group, what has been proved and what damage can be demonstrated.
Values Legal certainty, proportionality and careful assessment of evidence.
Consequences Proceedings would take longer, but would prevent all motorhomes or all owners from automatically being treated alike.
Right
Arguments Manufacturers must be able to defend themselves against broad mass claims, and consumers should not be encouraged to take part before liability has been established.
Values Property rights, contractual certainty and restraint concerning collective liability.
Consequences A higher evidential threshold protects companies against unsubstantiated claims, but may disadvantage individual consumers with limited means.
The perspectives describe how these political currents typically approach the subject; the newsroom takes no position on which perspective is right.
