2 known faults with sources

Engines: 1.2 Hybrid (Hybrid)

Water ingress in the 1.2 Hybrid 48 V belt starter-generatorElectrical and electronic systems

Engine / equipment: 1.2 Hybrid 48 V: Peugeot 208 and 2008, Citroën C3, C3 Aircross, C4 and C4 X, DS 3, Opel Corsa, Frontera and Mokka, Jeep Avenger, Alfa Romeo Junior, Fiat 600 and Grande Panda, Lancia Ypsilon
Period mentioned: 2023 onwards
Symptoms: Engine or electrical-fault warning light, a hot or burning smell under the bonnet and, in extreme cases, an engine-bay fire.
Possible cause described: There is too little clearance between the petrol particulate filter duct and the 48 V hybrid system’s guard (belt starter-generator): in humid conditions water can get in, an electric arc can form and it can overheat. Stellantis recalled about 700,000 cars worldwide (36 incidents, 12 with fire) and advises against pressure-washing the engine until the repair.
Check for the garage: Check the recall by VIN; do not pressure-wash the engine; with the warning or a burning smell, stop and park outdoors.

Badly calibrated Matrix LED headlights and a lane departure warning that switches off (Alfa Romeo Junior)Electrical and electronic systems

Engine / equipment: Early Alfa Romeo Junior hybrid and electric cars
Period mentioned: 2023–2025
Symptoms: The Matrix LED headlights do not adapt the beam properly by themselves; the lane departure warning switches off without warning in bends above 90 km/h.
Possible cause described: Two recalls from March 2025: 6968 (more than 6,400 cars), for a wrong calibration of the Matrix LED headlights, fixed by a new learning procedure for their control unit (according to Autoblog, hybrids built from September to December 2024 and electric cars assembled from May to December 2023), and 6977, for an incorrect calibration of the electric power steering that can switch off the lane departure warning in bends above 90 km/h; it is fixed with software.
Check for the garage: Check campaigns 6968 and 6977 by VIN at an Alfa Romeo dealer.
