Electrical system
I was driving and antitheft system went off while driving. Then wiper failed to work. I was told by dealer mechanic that the body control module was failing and advised not to drive the car because the antitheft system may cause the car to stop and the wiper system will stop when raining causing multiple accidents.
I was driving on the freeway and turned the seat heater on. After about 5 minutes into my drive, I started to smell smoke and then saw smoke in the car. I pulled over and saw that the seat was catching on fire. I turned the seat heater off and doused the fire with water.
Lights
GM3 Body module failure interior lights dont function, alarm whipers sprayers locks doors dont funtion
I have a complete failure of the passenger(right) side tail light assembly on our 2003 BMW 525i. The tail light is connected to a wiring harness via a connector. One of the connector pins has been overheated by the electrical current and has been burnt to a crisp. This exact problem has forced BMW to do a recall in 2011 on the 3-series of automobiles and yet they have ignored the safety of series-5 owners and have yet to issue a recall for this highly dangerous component failure. This failure causes the driver into believing that they have working turn signals when in actuality they do not. The vehicle still provides the sounds and sights of a directional being used, however, the lighting system is dead.
