The limits and issues of PureTech engines
Recurring technical problems
PureTech engines, despite their many advantages, are not without flaws. Among the most notable issues:
- Fragile timing belt: this problem, acknowledged by PSA, leads to premature wear and can result in serious consequences such as engine failure.
- Excessive oil consumption: many users report excessive oil consumption, which can affect the longevity and reliability of the engine.
- Vacuum pump failure: this malfunction can impair the proper functioning of braking and power steering systems.
- Overheating: repeated overheating of the engine can cause significant internal damage.
Recalls and corrective actions
In response to these failures, Stellantis has been forced to launch several recall campaigns. On November 20, 2020, 220,000 vehicles equipped with PureTech engines were recalled for timing belt issues and excessive oil consumption. The European Commission and RappelConso issued recall notices to inform owners of potential risks.
Reactions and measures
Despite these actions, Stellantis does not acknowledge a widespread design problem. However, the group compensates customers on a case-by-case basis. Christophe Lèguevaques, a specialized lawyer, is considering legal actions to defend affected consumers. Consider these aspects before acquiring a vehicle equipped with these engines, especially second-hand.
The reliability of PureTech engines remains a topic of debate. While their performance is undeniable, their recurring technical problems raise questions about their durability.
