The 2002 BMW 7 Series has 4 recalls, the most serious being a fuel pump defect on 745i and 745Li models where the pump can wear internally and fail to supply enough fuel to the engine when the tank drops to about one-third full or less.
On the brake side, a check valve in the brake vacuum pump can leak oil into the brake booster over time, gradually reducing or, in extreme cases, eliminating power-assisted braking. This makes the brake pedal significantly harder to press and increases stopping distances. There is also a software issue affecting 745i and 745Li models where a bug in the engine management system can cause the variable valve timing motors for the two engine banks to fall out of sync, resulting in rough running.

At a glance
What can fail
A software error in the engine control unit can cause the valve timing motors on both sides of the engine to become out of sync, making the engine run roughly. The check engine light and a warning message appear. In severe cases, the engine may stall and not restart.
What the fix does
The dealer will update the software in the engine control unit to correct the synchronization error.

At a glance
What can fail
The electric fuel pump runs too slowly, causing inadequate lubrication of internal parts. Over time, this wear damages the pump, reducing fuel supply when the tank is one-third full or less. The engine may stall and fail to restart until more fuel is added, even though fuel remains.
What the fix does
Dealers will reprogram the fuel pump control system to correct the pump's running speed.
