What to watch for
The list covers the generation, the engines and the transmissions. Once you pick the version, only the faults that apply to it stay.
The multi-part crank hub is held in place only by the clamping force of the crankshaft bolt and the friction between the mating surfaces.
Applies to the engine S55B30.
The engine oil is cooled by an air-to-oil cooler, and it sits under the front spoiler, perpendicular to the ground.
Applies to the engine S55B30.
The connecting rod bearings wear from as little as 60,000 kilometres, which is early even for an engine of this output.
Applies to the engine S55B30.
Valvetronic adjusts the lift of the intake valves, and an eccentric shaft does that work.
Applies to the engine S55B30.
The maker builds the charge pipe out of plastic, and the coupler at the throttle body is the critical point.
Applies to the engine S55B30.
Repair: 100–400 EUR
The manufacturer fixes these for free at a franchised dealer. Ask with the VIN whether it was done. The list covers the whole generation. We did not filter it by model year. Some apply only to a narrower production window.

A12/00868/23Safety recallInjuries30 March 2023 · EU Safety GateThe airbag may deteriorate over time, and if deployed, excessive internal pressure may cause the inflator body to burst and metal fragments could pass through the cushion material causing injury to occupants. The product does not comply with the Regulation on the approval and market surveillance of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles.
Remedy: Type of economic operator taking notified measure(s): Manufacturer Category of measure(s): Recall of the product from end users Date of entry into force: 30/03/2023
A12/00134/21Safety recallFireno date · EU Safety GateThe fuel injectors may not have been equipped with a decoupling element. This could result in a vibration fracture at the soldering point of the high-pressure fuel rail. Consequently, fuel could leak into the engine compartment, increasing the risk of fire.

A12/01223/24Safety recallInjuriesno date · EU Safety GateThe accumulator in the driver/passenger head airbag inflator can leak, preventing the airbag to fully deploy if activated in an accident, impairing the protective effect of the airbag. Moreover, the accumulator can detach, entering the interior of the vehicle or becoming detached from the vehicle. This can lead to an increased risk of injury for passengers and/or other road users. The product does not comply with the Regulation on the approval and market surveillance of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles.

A12/01981/24Safety recallInjuriesno date · EU Safety GateA seam on the inflator housing of the driver airbag may not have been correctly welded. In case of accident, when the airbag is deployed, the inflator can burst, releasing metal parts which could cause injuries. The product does not comply with the Regulation on the approval and market surveillance of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles.

Common questions
2013–2020. The changeover year can fall in two generations. If the listing is from that year, look at the neighbour too.
No. It depends on the engine and the transmission too.
