Jeep Avenger: Most Common Problems and Breakdowns Found in 2025

Article updated on May 5, 2025

The Jeep Avenger , the first 100% electric SUV (also available in a mild hybrid version) from the American manufacturer owned by Stellantis , has enjoyed good sales success thanks to its modern design, compact size , and urban versatility . However, during 2024 and the first months of 2025, some recurring issues emerged, reported by owners and service centers.

1. 1.2 PureTech Engine Problems

One of the most common defects concerns the 1.2 PureTech engine (also used in many other Stellantis models, such as the Peugeot 2008 and Opel Mokka). In particular, premature wear of the timing belt has been highlighted, which can fray and cause serious engine damage due to oil contamination.

This problem affects both naturally aspirated and turbocharged versions, and often occurs well before the mileage limit for belt replacement. Some documented cases have required a complete engine replacement under warranty.

• Engine lights on

• Loss of power

2. Oil Leaks

Another recurring defect is the loss of engine oil , with critical points located in:

• Cylinder head gasket

• Oil pipes

• Lower casing

These leaks, if ignored, can compromise lubrication and lead to major mechanical failures .

3. Start & Stop System Malfunction

Many users have reported anomalies in the functioning of the Start & Stop system, with symptoms such as:

• Inconsistent activation/deactivation

• The system remains inactive even with a charged battery

• Slow engine restarts

In some cases, the problem is related to an unsuitable battery or malfunctions of the environmental sensors .

5. Clogged Diesel Particulate Filter (DPF)

Thermal versions equipped with a particulate filter (DPF) can suffer from frequent blockages , especially when driving predominantly in urban areas. This leads to:

• Performance reduction

• Increased consumption

• Engine fault lights on

In the worst cases, forced regeneration or filter replacement is necessary.

Conclusions

The Jeep Avenger represents an interesting proposition for those looking for a compact and modern SUV, but it is essential to be aware of the known flaws that have emerged up until 2025.

✅ Helpful tips for owners:

• Perform timely maintenance (especially the timing belt)

• Use quality lubricants and check levels often

• Avoid journeys that are too short (to prevent DPF problems)

• Carefully monitor the efficiency of the Start & Stop system

Anyone considering purchasing a Jeep Avenger would do well to consider these aspects, especially if the goal is to have a car that is reliable in the long term and with low maintenance costs .
