What 2006 BMW Z4 owners say
Steering all 55 →
The Steering wheel gets Hard, looks like power steering gets disabled automatically while driving, making it almost impossible to steer. This has started to happen after hot weather had started few months back. I have tried to reproduce this issue several times, but it happens randomly and Not all the time. I don't drive the car much. But this is definitely a serious issue, I checked the BMW community and a lot of people are facing this issue. Not Sure how many have filed a complaint here. But this definitely should be addressed by BMW as this is not just one person facing this issue, there are hundreds and thousands of them. Level of severity is high, as someone who might have not faced this issue yet might suddenly face it on the highway could result in an extremely fatal accident. …
When the outside temperatures are warmer (mid 80's and above) the steering wheel will stick in the center position and require it to be jerked a bit to keep control. This occurs at all speeds, but does not seem to be the case when stopped. since it requires the steering wheel to be jerked to correct, it can cause the car to swerve. I have had the car for several years began noticing the issue once the weather got warmer. The date entered below is today's date, but I have had the issue for perhaps 5 years.
Air bags
Front passenger air bag sensor warning light on - passenger air bag will not function in event of collision. Passenger air bag sensor warning code can not be reset. The car air bag system has never been activated by collision. The front passenger air bag warning light first appeared when starting the car in garage and is not associated with any collision events. It appears to be linked to similarly reported BMW models recalls involving the front passenger seat air bag sensor mat failures, which requires seat air bag sensor mat replacement. The problem is it is not clear if current air bag sensor mat recalls include and cover the BMW 2006 Z4 passenger air bag seat sensor mat replacement. The car was purchased from BMW dealer as a pre-owned certified car under full warranty. …
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. …
Electrical system
I have just found out that my 2006 BMW Z4 Convertible has serious wiring issues. The wires for example on my front headlights the insulation is falling off the and leaving bare wires. I am very concerned this could be a fire safety issue that could result in bare electrical wires shorting together and starting a car fire. My research shows that many people who have 2006 BMW Z4 Convertibles are having this same issue. This seems to be a real issue with BMW using cheap wiring harnesses material and over time due heat and cooling is cause the insulation to fail and resulting in this issue.
