Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2006 BMW Z4 Owner Comments

problem #9

  • 65,000 miles


My car had approximately 65K miles on it when the light on the dashboard indicated an issue. It was manufactured in 08/06. Reading from the computer indicated a passenger occupancy mat failure. BMW extended the warranty for 10 years through model year 05 but won't do anything for 2006. I called BMW usa and escalated it. They called me back and stated it will not be covered. I am concerned that this may prevent the airbag from operating in case of a collision for the passenger. There are many complaints about the 2006 model occupancy mat with this my and I think BMW should be forced to cover this safety hazard. The car was purchased from BMW dealer as a pre-owned certified car under full warranty. The dealer would not address repairs under the current recalls. This should be covered the same way as previous model year Z4 vehicles. According to recall 13V-564 this should be covered but BMW says no!

Spring in steering wheel that is part of air bag causes warning light. Less than 50 K miles electrical issues. Have had 2 replace the batteries twice in 5 years. Having to replace the blower motor twice, and the console controls for air conditioner and heater. Lastly, when the engine is warm and you come to a stop light, the engine surges drastically. BMW service claims that it is normal. And

Changing a headlight bulb on drivers side noticed flaking insulation on wiring harness. In the process of removing headlamp, insulation on all the wiring almost completely disintegrated. I can only assume that this same condition exists on the passenger side. This would seem to present a fire hazard at worst and a loss of lighting at the least. I understand from reading various forums that this is a problem across many BMW models. Further, it appears that BMW used a soy based insulation product on these wires. Isn't soy biodegradable? why would this be used in a wiring harness.

The battery on the vehicle was dead and replaced. After the battery was replaced, the vehicle is in "transportation mode". under this mode, the ac, fan and rear defroster do not work. The vehicle need to be returned to the dealer to reinitialize the software to remove the transportation mode.

On my 2006 BMW Z4 3.0I, while replacing a blown headlight bulb I discovered that the insulation on the low beam headlight wiring was crumbling off and in parts had bare copper wire showing. As this is the main headlight wiring and both the + and - wires were showing bare copper a short circuit and or fire could be possible. This wiring is within the headlight housing it's self. Upon doing research online I am not the only person affected. I reported this issue to my local BMW dealer who said there were no recalls at this time and I could call BMW na. I called BMW na who repeated that there was no recall and said they would make a note of it but offered no other help.

All service and repairs of this cpo performed by dealership. Fire caused total loss of vehicle in excellent condition melting interior and nearly burning driver-damage most severe on driver's side of vehicle and extends to the car exterior. Fire started while vehicle moving on heavily used public road shortly after warning symbol for blinkers activated and blinkers on passenger side increased in speed.

The steering wheel intermittently locks up at higher speeds (50-70 mph). Usually the issue happens when the temperature is above 85 degrees.

Passenger airbag deactivation light always on (since 20,000 miles approx) together with dashboard airbag warning light. Garage diagnosed faulty passenger seat pressure mat and advised passenger airbag would not deploy in the event of an accident. BMW norwell MA, who sold the car to us, stated no recall on 2006 model (conversation with their service dept. Of 10/21/2011) although all Z4S up to 2005 were recalled for mat replacement. BMW were clearly still fitting defective pressure mats in the 2006 models and would appear to be not only jeopardizing our safety but also avoiding their responsibilities.
