Here are the deets on the 1991 BMW 735I: 3 recalls, 2 owner complaints and up to 16 mpg combined.
Recalls
3 vehicle recalls from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.
Exterior lights Vehicle recall #96V111000 · 1996 · 180,000 vehicles
What's wrong: The brake light switch can fail allowing the switch to remain in the "brake lights off" position or in the "brake lights on" position.
Why it matters: If this happens, the brake lights either will not operate or will be continuously on, regardless of brake pedal position. Following drivers would not be able to determine whether the vehicle is stopping, increasing the potential for a vehicle accident.
The fix: Dealers will replace the existing brake light switch with a newly designed switch.
Airbags Vehicle recall #96V110000 · 1996 · 75,000 vehicles
What's wrong: The air bag contact ring locking tab located in the steering wheel assembly can break without warning.
Why it matters: If this happens, the contact ring wiring could eventually break. The air bag readiness indicator lamp (SRS or airbag) in the instrument cluster will illuminate, and the air bag would not deploy in the event of a frontal impact vehicle collision.
The fix: Dealers will replace the locking tab with one of a different design.
Engine & cooling Vehicle recall #98V178000 · 1998 · 340,000 vehicles
What's wrong: A malfunction or failure of a coolant system component, such as a thermostat, water pump, or fan belt, can result in significantly increased coolant temperature and system pressure. If the indications of a critical overheating condition is not noticed by the driver, it is possible that damage to, or failure of, a coolant system component could occur.
Why it matters: If a crack were to form or a seam were to separate in the heater core end piece, hot coolant could suddenly be expelled, increasing the risk of personal injury to a vehicle occupant.
The fix: Dealers will install a new design radiator cap to control pressure and provide greater coolant overflow in the event of overheating.
