I almost had a terrible accident in my 2 week old 2018 M5 on the 1-95 highway on the night of may 25, 2018 at about 9:45pm. Without warning, at about 65mph, the car jerked for about 3seconds , kicked out of drive into neutral and started decelerating. I was in the middle lane surrounded by speeding vehicles. I managed to guide it to the shoulder and turned off the ignition for 2minutes, after which I re-started the car and was able to engage drive. I contacted my dealership today, only to be informed, this was as a result of computer glitch controlling the fuel pump causing it to shut off without warning. I was told there has been a software patch to remedy this problem. If it is true, I believe the correction should have been done before the car was picked up or promptly notified to return the car for fixing. I could have been killed on the highway last night if not for my prompt situation awareness and experience in handling this powerful car which is my fourth M5 since 2006. Owners need to be notified immediately for fixes like this that can lead to fatal incidents. I don't know if anything similar has been reported about this model.

The early M5 with the smg (sequential manual gearbox) 7 speed have numerous TSB's and warranty campaigns. The shifting of the gearbox is up executed by pressure from the hydrualic pump that stores aaprx 80psi in the accumulater. This accumulator or pump has a hi chance of failing and when it does the car shuts down without warning. My car shut down in the middle of the intersection just recently. And I have had this pump replace twice out of warranty and once within warranty. A major flaw of the getrag smg 7spd. BMW discontinued this transmission but continues to raise prices on the replacement pumps as they know there is a high turnover of repairs. Please visit the BMW m forums as this topic is heavily discussed.

With an smg transmission, when accelerating from a complete stop, there is a loud thump in the the rear of the car as if somebody hit you from behind. It is very startling and I am sure something is wrong with the car. This is a common complaint among all BMW M5 drivers. I am surprised nobody placed a complaint about this yet.
