2020 DS DS 3 Crossback problems

The 2020 DS DS 3 Crossback was sold with 3 engines that we have documented: the 1.2 PureTech, the 1.5 BlueHDi and the Stellantis e-CMP (e-208, Corsa-e, ë-C4…). All of them have serious faults that affect the cars of that year. The safest option is the Stellantis e-CMP (e-208, Corsa-e, ë-C4…) (verdict “With caution”). Outside the engine, one documented fault affects 2020 cars, such as risk of a short circuit in the 12 V battery under the bonnet (built February-July 2020).

Our score goes from 5.5 in 2019 to 5.5 in 2020. No longer affected by: wrongly positioned brake hose, with a risk of breakage (built April-December 2019) (rest of the car). Starts to be affected by: on-board charger and charging port: AC charging refused or interrupted (Stellantis e-CMP (e-208, Corsa-e, ë-C4…)) and risk of a short circuit in the 12 V battery under the bonnet (built February-July 2020) (rest of the car).

According to our score, the best is 2022 (6.7/10). The year with the worst score is 2019 (5.5/10). Each year's score counts only the engines sold that year and the faults that affect those cars.

The most important ones documented for 2020 cars are: oil-bath timing belt degradation (1.2 PureTech, critical severity), wear and breakage of the 7 mm chain between the camshafts (1.5 BlueHDi, critical severity), risk of a short circuit in the 12 V battery under the bonnet (built February-July 2020) (electrical system, critical severity), excessive oil consumption from carbon on the piston rings or oil separator failure (1.2 PureTech, high severity) and seizure of the high-pressure pump and injection system (1.5 BlueHDi, high severity).
