Jeep Avenger 1.2 e-Hybrid Mk1

The Stellantis e-DCS6 electrified dual-clutch gearbox (developed with Punch Powertrain) has attracted widespread complaints since launch. Drivers report severe jerking and knocking when the system transitions between electric and petrol power, particularly in stop-and-go traffic. Symptoms include hesitation when pressing the accelerator, rubbing noises at 30-50 km/h, and sudden transmission lock-ups with error codes P1749 00 and P28EA 62. Some failures occur as early as 10,000-15,000 km, with reports of eccentric parts breaking internally. Stellantis acquired full ownership of the transmission production from Punch Powertrain in early 2025, partly in response to quality concerns. Many issues can be addressed with software updates, but mechanical failures such as clutch pack wear or mechatronics faults require component replacement. Dealers have reported multiple vehicles waiting simultaneously for new gearboxes, suggesting supply-side pressure.

Stellantis recalled approximately 700,000 vehicles across Europe (including the Avenger) for insufficient clearance between the gasoline particulate filter pipe and the 48V Belt Starter Generator (BSG) protection cap. Under wet conditions, this gap can allow water infiltration and electrical arcing, potentially leading to overheating or fire. Globally, 36 incidents were recorded, of which 12 resulted in engine compartment fires. No injuries have been reported. The fix involves replacing the BSG protection cup (approximately 30 minutes of workshop time, performed free of charge). Verify with VIN that this has been completed. If not yet addressed, this is a priority safety concern. Vehicles manufactured between 2023 and 2026 are potentially affected.

Recall code 58C affects Avengers manufactured between 16 January 2024 and 17 May 2025. Insufficiently tightened nuts on the high-pressure hose between the fuel pump and injection rail can cause fuel leaks, creating a fire hazard. The fix involves retightening or replacing the connection (performed free of charge at dealers). This recall was issued as a Serious alert via the EU Safety Gate (RAPEX Alert 33/2025). Verify with the VIN that this has been completed before purchase.

The Uconnect infotainment system is prone to software instability, particularly in the first 2,000-8,000 km of ownership. Symptoms include frozen touchscreens, slow response times, spontaneous Bluetooth disconnections, and navigation system crashes. A temporary fix is holding the volume and tuner knobs simultaneously for 10-15 seconds to force a reboot. Most issues improve with dealer-installed software updates, which are typically free of charge under warranty. If the car is outside warranty, a diagnostic session and software update at an independent specialist costs around €100-200. In rare cases, the infotainment head unit itself may need replacement (approximately €400 with installation).

The electric tailgate on higher-spec Avengers (if equipped) can exhibit delayed or non-responsive opening after 5,000-12,000 km. The hands-free foot sensor often fails to detect kicks reliably in wet or cold weather. Gas struts may lose strength prematurely (around 15,000 km), and electrical contacts can corrode, causing intermittent failures. Sensor recalibration often resolves software-related issues. Gas strut or motor replacement costs €200-400 for parts plus labor. Regular cleaning of contacts and sensor areas extends service life. Not all trim levels include the electric tailgate.

Many owners report the Start/Stop function displaying 'Start & Stop not available. Recharge battery' even when the battery appears fully charged. The system is sensitive to battery charge levels and temperature, and will deactivate when conditions are not optimal. Using a non-AGM battery type causes persistent malfunctions. In some cases, the system fails to restart the engine promptly, causing uncomfortable delays at traffic lights. Firmware updates (particularly for 2023-2024 models) have resolved many of these issues. A proper AGM or EFB battery replacement costs €150-250. Sensor recalibration at a dealer costs around €50-100.

Certain Gen3 EB2 engines manufactured between 2023 and 17 February 2024 have a camshaft phaser defect. An incorrectly positioned camshaft sprocket screw can cause power loss, engine warning lights, misfiring, abnormal engine noises, and premature timing system wear. This is an assembly defect (not a design flaw) that was corrected with a camshaft phaser upgrade on 31 January 2024 and a new pinion screw specification from 18 February 2024. Vehicles produced after this date are unaffected. If the car was built in this window and has not been remedied, repair involves camshaft phaser replacement. Verify production date and check for any outstanding technical service bulletins.
