Certain 740ILA, 750IL and M5 vehicles equipped with 18-inch tires. (18-inch tires are standard equipment on the M5 and optional equipment on the 7-series models). The machine used to mount and inflate the tires on the wheels at the assembly plant may have damaged the sidewall of one or more tires. The damaged area could weaken to the point where a sudden loss of air from the tire could occur. Handling and control would be drastically affected increasing the risk of a crash. Correction: dealers will inspect the tires and if damage from the mounting machine is found, the tire will be replaced.
On certain 323I, 328I, 528I, 528IT, 540I, 540IT, 740I, 740IL, 750IL and M5 vehicles, the brake light switch capacitor housing may be cracked and in high humidity conditions the capacitor and switch housing could become overheated and deformed. As a result, a short circuit or an open circuit could occur in the switch. This could cause the switch to remain either in the "brake lamps off" position or the "brake lamps on" position. If the switch remains in the "off" position, the brake lamps will be rendered inoperative. Conversely, if the switch remains in the "on" position, the brake lamps will be continuously illuminated when the ignition switch is in the "on" position. Correction: Brake lamp switch will be replaced with an improved switch.
