Water linkage down door panels to the floor, Drivers side ECM is located in that area, water damages the components and caused it to produce codes, interfering with car engine, causes surges, and vehicle to all of sudden shut off even while driving on freeway or streets. Water linkage on the passenger side down into the fuse box. All so causing electrical malfunction that opens the door for potential unsafe events.

Took in for repair for water getting into car several times to dealer. Told they could not find a problem or where any water was getting into car. The last time I took it in, told that they cleaned water lines etc. So, should be ok. However, after driving it home & once a good rain came, it got wet inside the cabin/car again! they had the car, worked on it etc. However, when it was picked up again, told that the dash screen was damaged. But rather than blame it on the water getting into the car etc.; they blamed it on something else which cost an unbelievable price to repair. Or they failed to admit their unbelievable car care and customer care/service. Subsequently, the lost of being able to see the car dash, screen etc.: all of the systems information: Gas level, speed, lights, navigation etc. Has been lost.
Vehicle was parked with engine off and spontaneously combusted. ** have video footage of the entire ordeal. ***** the car had been parked for roughly 4 hours prior to fire starting underneath the hood fo no apparent reason. Reached out to BMW and was told due to the severity of the damage their investigators could not determine the cause or origin of the fir at the time of the inspection. The national engineering group observed thermal damage isolated to the engine compartment with greater consumption towards the front. This occurred due to no fault of my own and BMW is denying responsibility and help.
Valve seals....there are way too many people having the same engine issue on these models for nothing to be done. The valve seals let oil blow by which results in massive oil loss and could result in engine failure. Then BMW wants everyone to pay thousands of dollars to fix their mess up.

Near miss a couple times..........whenever sitting still for a period of time then go to take off there is a big bluish gray smoke cloud. At the same time the car will take off then do a jerky stop and go again. I've almost been rear ended many of times. If sitting somewhere for longer then 2-3 minutes the car is surrounded by this smoke. Its a known issue with BMW. To me this is a safety issue along with environmental and health issue.
The oil cooler adapter plate is defective the O ring is defective and leaks oil all over everything including wires. If your car doesn't have an external oil cooler, the plate, with the O ring seal will leak oil. The other side has two holes that can be machined for the external oil cooler, but if your car does not have that feature you will have oil leaks. Common oil leak on the V8 N62 and N62tu engines that would be in the E65 7 series and the X5 E53. This is the bearing block where the alternator mounts to. There is a gasket that develops a bad leak because of the seal failing. The seal has no use to the engine it is just there just in case if you get the oil cooling option and if you choose not to get the option your car will leak oil because the seal is not substantial and the oil has no where to go, so it leaks out of the gasket. The leak can be quite substantial.
While driving at 25-30mph, the vehicle stalled losing all power including the power steering and having to coast into the breakdown lane. This is the second time in 3 months. After sitting for 15 minutes and 5-10 "no starts", the vehicle finally started and drove normally. The dealership is unable to replicate the event. There is a current power supply recall on several BMW models demonstrating the same symptoms. BMW states that the power supply on the 750li is different from those vehicles under the recall. This model should also be included as I have read several similar complaints on the BMW forums. This is a very dangerous safety hazard in which many BMW 7 series owners are experiencing.
