Brake lights on both sides gets stuck on once the pedal is pressed. This produces no error codes. I was told it could be the brake pedal pressure sensor switch. I changed this and it did nothing. This is very dangerous to other drivers because they are not sure if the car is braking as the light is always on and will burn out the bulbs and melt the housing if constantly on. This can be reproduced either while parked or in motion.
BMW e46 3 Series - zkw headlights- very low light output the zkw headlights have a design flaw in which after 2-3 years of use, they dim to around 20% of the original light output. This is very dangerous when it comes to night driving. Someone driving with this issue is nearly completely blind driving around at night. This is due to the projector reflector bowl being made out of plastic, and melting from the heat. This causes the light to bleed out from the backside of the light into the housing, instead of forward onto the road. BMW noted this flaw by replaced the zkw headlamps with al branded headlamps in all the newer bmws in 2005 and on. The al branded headlights replaced the plastic bowl with metal bowls. However, all e46 3 Series sedans from 2003-2004 still have these faulty zkw headlamps. There is no easy fix to this problem, as BMW does not sell the bowls separately. …
Air bags all 21 →
Last year we were notified by BMW us that our car was being recalled for the passenger side airbag malfunction and BMW dealers were responsible to fix the problem. Since then we have contacted BMW us numerous times and our local san francisco BMW dealer to schedule an appointment. Unfortunately, we were repeatedly told the same answer that we will have to wait until the parts are available for replacing the air bag. Finally, we were able to set up an appointment with our BMW local dealership for February 4, 2015. When we took the car there, we were told once again, by their 'service consultant rubi huey, that there are still no parts available to fix it and they could not even give us an approximate date as to when they would take care of this serious problem. …
I was traveling n/b on route 1 in elkridge maryland @ intersection ducketts lane on 10/9/14 @ 4:47 pm. I was involved in a 4 car pile up crash, I was stopped - the vehicle behind me was struck by a speeding motorist which caused a chain reaction & struck my BMW and knocking me into the vehicle in front of me. Both front airbags exploded with caused a severe burn to my right hand. My vehicle was a total loss and the at-fault driver's insurance has possession of the vehicle. I was immediately taken by ambulance to the hospital with other injuries. Appropriately two weeks before the accident, I received a letter stating that there was a recall on my vehicle, and parts were not available to fix the vehicle, and I would be contacted at a later time. …
Electrical system
Transmission will drop out of gear and shut car down, while vehicle in motion during normal use. Vehicle will only work when cold, manufacturer is aware of badly designed smg temp sensor and negligently designed computer logic that shifts transmission to neutral and shuts car down.
I was locked in my car for 1 hour. My key fob would not unlock my doors, so I manually opened the door, started the car, closed the door, and tried to warm up the car (it is winter in chicago and my windows were also frozen shut). I then pressed the door lock button twice in an attempt to unlock the doors and at that point I learned I was locked in my car. I tried driving the car a block to see if the locks would reset and nothing worked (neither the door levers, key fob or lock button). I called a dealer and they suggested I drive it to the service center. When I arrived at the service center an hour later, my window was no longer frozen so I handed the key to the agent and although the manual door handles and unlock button would not work, the key fob was able to unlock the doors. The agent agreed that there was a problem that needed to be inspected. I drove the car home. …
