3 known faults

PureTech 82

  1. Degraded 'wet' timing belt (1.2 PureTech)

    Severity 3/3 · Serious

    On the 1.2 PureTech, the timing belt runs in oil and can break down. Its debris clogs the oil strainer, which causes oil pressure to drop and can destroy the engine. Stellantis extended the belt warranty to 10 years or 175,000 km, subject to servicing conditions, and introduced a new-generation belt in June 2022.

  2. Oil consumption (1.2 PureTech)

    Severity 2/3 · Costly

    Beyond belt wear, the 1.2 PureTech is known for high oil consumption, which can lead to engine damage if the level is not monitored. According to Caradisiac, engines built from 2023 onward are no longer affected.

BlueHDi 100

  1. Premature wear of the timing chain (1.5 BlueHDi)

    Severity 3/3 · Serious

    On the 1.5 BlueHDi (DV5), the 7 mm camshaft chain can lose strength because of oil carbonisation and high contact pressure, then break, causing the engine to stop abruptly; the wear may show up as an unusual engine noise. C3 Aircross cars with the 1.5 BlueHDi built between 10 October 2017 and 30 January 2023 are subject to a recall (Citroën code NY5): the chain is replaced by a reinforced 8 mm chain. Citroën has also extended its special chain coverage, subject to servicing in line with the manufacturer's plan.
