The 2003 BMW 7 Series has 3 recalls, the most serious involving a potential complete loss of power-assisted braking if a brake vacuum pump check valve leaks oil into the brake booster over time.
On the engine side, certain 745i, 745Li, and 760Li models may have had the oil filter drain plug installed without enough torque. If the plug loosens, it can spray oil and then leak steadily, creating both an engine lubrication risk and a potential fire hazard if oil contacts hot exhaust components. The third recall affects vehicles with heated seats: repeated contact with the outboard side bolster when getting in and out of the vehicle can damage the heating mat in the seatback. A damaged mat can overheat that section of the seat, and in some cases burn through the upholstery, exposing the occupant sitting against it to excessive and uneven heat.
