Five problems related to electrical system have been reported for the 2004 BMW 545. The most recently reported issues are listed below.
My I drive or ccc has malfunctioned. At first the screen would turn on and off or freeze up. Finally the screen went blank. This unit provide the safety information of the vehicle. This unit also provides the communications such as bluetooth and hands free functions. This unit also provides all the service information/ basically it like driving a vehicle with out a brain. This seems to be a recurring problem with other BMW owner.
I recently purchased a 2004 BMW 545i. On the second time having a passenger in the car, while driving down the highway, I was alerted by a chime and message that the passenger side airbag / safety restraint system had failed. Also noticed was that when turning on the driver's seat heater, the seat got very hot in one particular spot- on the left side near my hip (hot enough that I received a minor burn on my leg through a pair of jeans). I contacted BMW customer service about the problem, as I was made aware that there were recalls on other models for the same reasons, and was told that there were no open recalls for either issue on my model. The representative simply explained that the vehicle was out of warranty and that fixing the issues would be at my expense. I believe that these are very serious defects that could affect my safety and the safety of my passengers.

Transmission jerks and slips. When coming to a stop, the car slams into gear. This could cause a major accident if this occurred during wet or icy road conditions due to breaking traction from wheels and road surface. This is a major concern and after doing some research, thousands of 5 series BMW's have this problem. The result is a defective mechatronics which costs between $5000-$8000 to fix and not covered by BMW or under warranty.
Vehicle slips in an out of 5th and 6th gear when traveling at constant 35 to 40 mph in auto mode and around 60 mph in ds mode. Noticeable oil leaks as well as occasional smoke from tailpipe and vehicle bangs into gear ( while downshifting on occasion) also noticed that the electrical system seems to cut out for a split second while driving. Heads up display and radio illustrates this finding as they shut off for a second. The clock is also behind a few minutes / week because of this.
