The engine simply stops, leaving drivers stranded
En Chile, la protección del consumidor cumple una de sus funciones más silenciosas pero esenciales: interceptar el peligro antes de que llegue a la carretera. El Sernac alertó sobre casi dos mil vehículos de las marcas Citroën, Opel y Peugeot —vendidos entre enero de 2025 y junio de 2026— por un defecto en la polea de la bomba de agua que puede provocar el apagado repentino del motor. La mayoría de los autos aún no ha llegado a manos de consumidores, lo que sugiere que el sistema funcionó: el problema fue identificado y reportado antes de convertirse en tragedia.
- Un fallo mecánico silencioso —una polea que se desplaza de su posición— puede detener un motor en plena autopista sin previo aviso.
- De los 1.956 vehículos afectados, 153 ya circulan en manos de consumidores que podrían desconocer el riesgo que llevan bajo el capó.
- Stellantis reportó el defecto a los reguladores chilenos antes de que se registrara ningún accidente, activando un proceso de alerta preventiva.
- El Sernac publicó los números de identificación vehicular afectados y habilitó líneas directas para que los dueños coordinen la reparación sin costo.
- Los 1.803 vehículos que permanecen en stock de concesionarios no podrán venderse hasta que el defecto sea corregido.
El Servicio Nacional del Consumidor de Chile emitió una alerta de seguridad que afecta a 1.956 vehículos de Stellantis —modelos Citroën Berlingo, Opel Combo, Peugeot Partner y Rifter— comercializados entre enero de 2025 y junio de 2026. El origen del problema es preciso: la polea que acciona la bomba de agua puede desplazarse de su posición de ajuste a presión, lo que desalinea la correa de distribución y provoca el apagado del motor. Antes de detenerse por completo, el vehículo pierde potencia de forma progresiva —una señal de alerta que, en una ruta de alta velocidad o en una curva de montaña, puede no llegar a tiempo.
Lo que hace notable este caso no es la magnitud del defecto, sino su detección temprana. Solo 153 de los vehículos flagueados están en manos de consumidores; los 1.803 restantes permanecen en inventario de concesionarios, a la espera de ser vendidos. Stellantis reportó el problema a los reguladores antes de que se registrara ningún accidente en Chile, lo que convierte esta alerta en un ejemplo de cómo debería funcionar la cadena de responsabilidad entre fabricantes, reguladores y ciudadanos.
Para quienes ya adquirieron uno de estos vehículos, el Sernac publicó los números de identificación vehicular (VIN) afectados y habilitó líneas telefónicas por marca: Peugeot (800 210 110), Opel (800 380 219) y Citroën (800 394 000). La reparación corre por cuenta del fabricante. Para los autos aún en stock, la corrección del defecto es condición previa a cualquier venta. Un llamado discreto, pero con consecuencias concretas: verificar un número, hacer una llamada, evitar un accidente que todavía no ha ocurrido.
Chile's consumer protection agency has flagged nearly two thousand vehicles for a potentially dangerous mechanical flaw that could leave drivers stranded on the road. The Sernac, the country's National Consumer Service, issued the alert after Stellantis Chile reported a defect affecting the water pump pulley in 1,956 vehicles sold under three of its brands: Citroën, Opel, and Peugeot. The problem is specific enough to be traced—it affects only certain model years and specific vehicle identification numbers—but broad enough to warrant urgent attention from anyone who bought one of these cars.
The defect works like this: the pulley that drives the water pump can slip out of its pressure-fitted position. When that happens, the timing belt loses alignment, and the engine simply stops. Before it stops completely, drivers would experience a loss of power—the car would begin to feel sluggish, unresponsive. On a highway, in traffic, or on a mountain road, an unexpected engine shutdown is not a minor inconvenience. It is a safety hazard. Stellantis acknowledged in its report to regulators that this condition could lead to traffic accidents.
The vehicles in question were sold between January 2025 and June 2026. The affected models are the Citroën Berlingo, the Opel Combo, and the Peugeot Partner and Rifter. Of the 1,956 vehicles flagged, only 153 are currently in the hands of consumers. The remaining 1,803 sit in dealer inventory, which means most of these cars have not yet been sold. That timing is significant—it suggests the defect was caught relatively early, before it could spread widely into the market.
Notably, Sernac confirmed that no accidents in Chile have been traced to this defect so far. That does not mean the risk is theoretical. It means the problem was identified and reported before it caused harm. Whether through routine quality checks, customer complaints from other markets, or internal audits, Stellantis caught the issue and disclosed it to regulators.
For the 153 people who have already purchased affected vehicles, the next step is verification. Sernac has published a list of vehicle identification numbers—the unique code stamped into every car. Owners of Citroën, Opel, or Peugeot models from this period should check whether their VIN appears on that list. If it does, they need to contact their brand's service center. Peugeot owners can call 800 210 110, Opel owners 800 380 219, and Citroën owners 800 394 000. Email addresses and dealership locators are also available on each brand's website.
The repair itself is not described in the alert, but the implication is clear: the pulley needs to be secured or replaced before the vehicle is driven. For dealers holding the 1,803 vehicles in stock, the defect must be corrected before sale. For consumers, the manufacturer is responsible for the fix. This is what a safety recall looks like in practice—a quiet but systematic effort to prevent a known problem from becoming a public crisis.

Some vehicles may experience engine failure with power loss caused by water pump pulley slippage, which could lead to timing belt misalignment and engine shutdown— Stellantis Chile, reported to Sernac
A Conversa do Hearth Outra perspectiva sobre a história
Why does a water pump pulley matter so much? It sounds like a small part.
It is small, but it's the link between the engine and the cooling system. When it slips, the timing belt goes out of alignment. The engine stops. On a highway, that's dangerous.
How did they catch this before people got hurt?
That's the question. Either someone reported it, or they found it in testing. Either way, it worked—only 153 cars had been sold when the alert went out.
What happens to someone who already bought one?
They call the number on the alert, verify their VIN, and take it to a dealer. The manufacturer fixes it for free. It's a recall, but quieter than most.
Is this a widespread problem with Stellantis, or just a one-time thing?
The alert doesn't say. It's specific to these models from this production window. Whether it's part of a larger pattern, we don't know yet.
What's the worst-case scenario if someone ignores the alert?
Engine failure on the road. Loss of power, then a complete stop. In traffic or at speed, that's when accidents happen. That's why they're being so direct about it.
