Stellantis Puretech engines break, burn and pollute

  • The manufacturer has sent a warning to some owners of the risk of fire.

The technical reports corroborate this, as thousands of users, victims of a factory failure, attest: the Puretech engines of the Stellantis Group are dangerous because they can catch fire.

Even the patent on the timing belt of these engines expressly warns that it must not come into contact with gasoline, a problem typical of all broken Stelantis engines. In other words, the manufacturer itself acknowledges and warns that its timing belt is not prepared to come into contact with gasoline, while all the expert reports indicate that the timing belts of the damaged Puretech engines have belts impregnated with gasoline.

This evidence makes those affected feel ignored by a company that recognizes that its engines are faulty at source but refuses to acknowledge it to the users who have trusted and bought their cars. Nor in the courts, where AFESTEL has already filed hundreds of lawsuits. We recall that since December 2024, conciliation lawsuits have been filed, which the company’s executives have refused to attend.

Recently, some owners of vehicles with Stellantis engines are receiving letters warning them that their vehicles could have

engine problems: “it could not be ruled out that a fire occurred in the engine compartment, which could lead to a vehicle fire.”

The expert reports are very clear:

  • On PureTech engines, the belt is made of materials that tend to degrade prematurely. During use, it releases particles that contaminate the oil. These particles not only affect lubrication, but can also clog oil lines and filters, reducing the pressure in the lubrication system..
  • On short trips, the engine does not reach its optimum temperature. This causes part of the injected fuel not to burn and ends up condensing on the cylinder walls. This fuel can mix with the oil through the piston rings.
  • PureTech engines use direct fuel injection, which improves efficiency and performance. However, this system can generate a larger amount of unburned fuel. This fuel can infiltrate into the crankcase and mix with the oil.
  • The combination of timing belt particles and fuel dilution degrades the quality of the oil, reducing its lubricating ability and increasing the risk of wear on critical engine components such as bearings and camshafts.

The Association of Stellantis Affected People (AFESTEL) currently represents more than 8,000 affected people, who are ready to go to court to defend their right to compensation, aware that the only way to force the company to find a solution to compensate for the economic loss is to act collectively.

Why should I claim?

Claiming is crucial to protecting your rights as the owner of a STELLANTIS vehicle with a 1.2 PureTech engine. Recurring problems with the oil bath belt can lead to serious mechanical failures and expensive repairs. By joining the collective action, you seek fair compensation and help pressure the company to take corrective measures.

Additionally, being part of this initiative allows you to join forces with over 5.000 owners who have already joined, strengthening the out-of-court claim and increasing the chances of success. The union of so many affected individuals not only makes the voice stronger, but also increases the pressure on STELLANTIS to solve the problem.

Don’t miss the opportunity to get the necessary repairs without incurring additional expenses. Claiming is not only a right, but also a way to ensure that your vehicle operates correctly and prevent future problems that may affect your safety and finances. Additionally, known issues can lead to a devaluation of the selling price of your vehicle, as the market becomes aware of the problem, affecting its value.

Finally, by participating in this collective action, you help set a precedent that can benefit other owners in the future. Joint action demonstrates that consumers have power when they organise and act together to protect their interests and demand justice.
