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.

When the car gets hot (parked in the sun) the steering becomes knotchy or sticky and the car becomes difficult to control. No problems whatsoever when the car is cool or on a cooler day. This problem has been witnessed by a BMW technician and there are no warning lights. This appears to be a fairly common issues with these cars.
