Nine problems related to electrical system have been reported for the 2004 BMW 3 Series. The most recently reported issues are listed below.

1 Electrical System problem

Failure Date: 05/24/2017

My vehicle unexpectedly started on fire as my daughter was driving to school. It was determined that it was an electrical fire, and resulted in the car being totaled. The 2004 models need to be included in the recall (not that it will help with the loss of my car).

2 Electrical System problem

Failure Date: 10/04/2015

The power door lock on passenger side cannot be unlocked either via remote or inside button. Worse, often when this happens, the door cannot be opened even by pulling on the handle from the inside! a passenger cannot get out of the car via the door. Furthermore, repeatedly attempts to have this fixed all fail within a short time.

3 Electrical System problem

Failure Date: 01/09/2015

I was not able to unlock my car with my car key. I was able to hear the click sound on pressing the unlock button on the key but nothing was happening. After numerous attempts for about 10 minutes car got unlocked. Now I'm having this problem on/off basis. I took the car to the local BMW dealer. After diagnose they said I have a failed general module which will cost me around $1000. This is way too much for car for it's total value of around $7000. This is scary since I'm not able to trust the locking system on my car. Sometime I'm not able to lock at all and at sometime I'm not able to unlock anything.

4 Electrical System problem

Failure Date: 11/01/2014

The heating element on my 2004 BMW x3 caught on fire while I was driving. I don't use it often, but had noticed a hot smell when I did use it and that it would be too warm in the lumbar and hip region. The fire actually burned about a dime size hole in the driver side left seat panel (under the thigh). After reading of many others having the same or worse experiences, I am glad I immediately shut if off, although it still burned all the way through the leather. Please advise me of next steps I should take. I have shut off the heater and will no longer use it. With so many complaints, I would think this would result in a recall. Thanks for your advice.

5 Electrical System problem

Failure Date: 02/18/2013

My bi-xenon headlights have been slowly fading resulting in extremely poor visibility during normal nightime driving. This degradation has been occurring without my knowledge until it became obvious after driving another vehicle. As it turns out, my mechanic has advised there is a common issue with certain BMW assemblies that the projector lenses literally burn due to heat resulting in the need to replace the entire assembly. This loss of headlight intensity resulting in poor visibility is a significant safety situation and request someone look into why no recall has occurred as this is obviously a safety concern. I have entered today's date as incident date as I am not sure when degradation of the projectors began.

6 Electrical System problem

Failure Date: 08/09/2012

Module that controls central locking, wipers, and several other parts (the gm5) started to develop a fault. We had problems unlocking doors, locking doors, using windows, and worst of all - the wipers were hit or miss. BMW wanted $750 for the part replacement.

7 Electrical System problem

Failure Date: 08/01/2012

As reported by other owners, the bi-xenon headlights no longer light up the road. It is a safety hazard and is a known issue with headlights manufactured by zkw on 2003-2005 BMW 330 models. The reflector bowls on these units burn out over time and reduce the headlight's ability to reflect light. Driving at night is literally no better with the headlights on or off. I have to rely on my fog lights just to see anything. Please look into this safety issue as it is wide-spread. Replacement of headlights is expensive at $1300 ea, this has to be resolved by BMW immediately.

8 Electrical System problem

Failure Date: 10/23/2010

2004 BMW 330xi sedan (e46) rear tail light indicator light consistently comes on, even though there is no tail lamp failure. Online community forums report that this is likely due to ground wire short in the tail lamp assembly. Cost of repair at dealership estimated at $700. Currently being investigated by NHTSA as ea09-019, but I'm wary of being overcharged by dealership for what should be a recall.

9 Electrical System problem

Failure Date: 02/16/2008

Door locks intermittently will not unlock with switch or remotes. Central locking does not work even when using the key fob. My kids and I have been trapped in the car on several occasions for up to 10 minutes. This is a serious risk to my life and the life of others on the road. BMW refuses to fix this problem. I have video of me trapped in the car. I addressed his problem with BMW before my warranty was up but they state since the technicians could not identity any problem it's not covered. I researched this issue and this is an ongoing problem with other customers.
