Exterior lighting: tail lightsReported September 11, 2013 · 134,100 vehicles affected
What is wrong
BMW is recalling certain model year 2008 through 2010 528i, 535i, 550i, and M5 passenger cars manufactured from March 1, 2007, through December 31, 2009. Over time, increased resistance at the taillight electrical contact points may cause damage to the ground terminal and housing of the connector resulting in an intermittent or permanent loss of functionality of one or more rear lamp functions (tail, brake, turn-signal, reverse).
Risk
Intermittent light operation reduces the ability to warn other motorists of the driver's intentions, increasing the risk of a crash.
Remedy
BMW will notify owners, and dealers will replace the rear lamp bulb carriers free of charge. Owners may contact BMW customer relations at 1‑800‑525‑7417 or email BMW at [email protected].

Recall number 13V407000 · Recall details

Electrical system: 12v/24v/48v battery: cablesReported March 26, 2012 · 367,682 vehicles affected
What is wrong
Bmw is recalling certain model year 2004-2010 5-series, model year 2004-2010 6-series, model year 2006-2010 m5, and model year 2007-2010 m6 vehicles. The insulated bulkhead connector for the positive battery cable may have been incorrectly attached to the trunk floor panel, which can lead to a loosening of the bolt connection. As it loosens, an increase in electrical resistance at this cable connection is possible and could cause the cable connection to overheat.
Risk
Overheating could lead to a fire, even while the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been made.
Remedy
Bmw will notify owners, and dealers will inspect and secure the battery bolt cable connection as necessary, free of charge. The safety recall began on april 30, 2012. Owners may contact bmw customer relations and services at 1‑800‑525‑7417.

While driving my bmw m5, the vehicle became momentarily unstable while driving on state route 52 between walker valley and ellenville around a turn @ ~50mph. Shortly after the ABS and dsc lights became illuminated. I have several vehicles so I did not drive this car and could not get repaired immediately due to covid-19. I am not sure the exact date in which this occurred but dropped off to orange county bmw on 5/19/2020. After inspection it was diagnosed that the complete dsc unit (hydro / electric) completely failed. Meaning there was altered stability control, ABS braking and come to find out steering. The steering sensors were diagnosed after the new dsc unit was installed and could not be programmed due to faulty steering sensors. Not only was this something extremely dangerous to happen, it was also extremely costly to repair. To bmw's credit they did cover the faulty steering sensors but the dsc unit that keeps the vehicle heading in the direction that you steer the car.....was not. I attached the invoice from bmw confirming all that was stated above. I am sure this has occurred numerous times before but I wanted to make sure this was documented.

All wires leading into the headlights have deteriorated and are bare. It keeps shorting out the lights and seems to be a major fire hazard. This is a garage kept car with 80k miles. Appears many many others have the same problem. Please help.

The sunroof drains of my vehicle overfill or clog causing water to leak in the trunk and wheel well. The cars wheel well holds the cars battery, rdc, and pdc modules. Surrounded by foam when water reaches the modules they arc and spark causing them to heat up and melt. Also located in the trunk is several other electrical components xm radio amp, etc. If not caught in time could cause fire and maybe even death. You can't tell when they are overfilled/clogged until it's to late. I have replaced them 2 times both times almost causing fire to the car. Here is a ling showing that bmw acknowledges the issue and is not fixing it. From someone else too.

On sept 25, 2014, I was driving my 2008 bmw m5 and turning into a parking lot when I was hit from the rear, shoved on top and over a median and into another vehicle. My vehicle was struck from the rear and then struck again from the front. I do not know how fast the driver that hit me was going, however, none of my airbags in my vehicle were deployed. I am unable to determine the exact characteristics in which each airbag would be deployed and I requesting the federal safety agency to perform that review.
