The engine demonstrates moderate overall reliability, based on a risk score of 5.0, which translates to an average level of anticipated operational challenges in practical use—neither exceptionally stable nor highly prone to failure. This assessment is supported by two known issues: one of medium severity, which may cause occasional disruptions without widespread impact, and one of high severity, potentially leading to more significant interruptions or performance degradation under certain conditions. These factors suggest a balanced but imperfect reliability profile, warranting consideration of maintenance and monitoring in deployment.

Common Problems & Weak Points
| Issue | Typical Mileage | Repair Cost (Est.) | Severity |
|---|---|---|---|
| Oil-Bath Timing Belt Wear | ~150,000 km | €1200 – €1800 | Medium |
| Integrated Starter-Generator Issues | ~120,000 km | €2000 – €3000 | High |
Oil-Bath Timing Belt Wear
This car has an oil-bath timing belt in the engine, which means the belt that helps synchronize the engine's parts runs through oil. It requires replacement every 4 years or at 150,000 km as a standard maintenance item, and this is a high-probability need for owners. The repair is a medium-severity issue with costs typically ranging from 1,200 to 1,800 EUR.
Typical Mileage: 150,000 km
Cost: €1200–1800
Integrated Starter-Generator Issues
This car model has a known issue with its integrated starter-generator, which is part of the 48V mild hybrid system. This component can fail, leading to situations where the engine won't start. It's a serious problem that requires replacing the part, and it typically shows up around 120,000 km. The chance of it happening is low, but if it does, the repair is expensive—usually between 2,000 and 3,000 euros—and it's considered a high-severity issue.
Typical Mileage: 120,000 km
Cost: €2000–3000
Buyer's Inspection Checklist
- Verify service records show the oil-bath timing belt was replaced within the last 4 years or 150,000 km to avoid costly future repairs.
- Inspect for any history of no-start issues, which could indicate failure in the 48V mild hybrid starter-generator requiring expensive replacement.
