BMW 440i

Where it stands out against its peers

• Engine and engine cooling: more complaints than 97% of 2018 cars — 21% of its 34 complaints, where an ordinary 2018 car has 2%.

Same model year only, at least 30 peer cars, zeros included. Every car has a worst part; this shows which, and how far from ordinary it is. A high share means more to check, not a verdict.

Specification

Recalls

Filed by the manufacturer with a regulator. A recall is repaired free of charge, whoever owns the car now.

74% of 2020 cars have more recall campaigns than this one, and an ordinary one has 3. More of them means more to check the service record for, not a worse car.

Regulator investigations

Opened by NHTSA's Office of Defects Investigation. An investigation is a question the regulator asked about a possible defect, not a fault it found — most end without a recall.

• Desiccated Air Bag Inflator Rupture

  Engineering analysis, opened September 2021, still open.

What the maker told its dealers

Service bulletins are the manufacturer's own repair guidance to dealers, filed with NHTSA. A bulletin is not a defect finding; the count rises with how many things a maker writes down, not only with how many go wrong.
