Recent owner complaints

The electronic steering has failed several times while driving. This makes it very difficult to maintain a lane and avoid other vehicles. This problem continues intermittently. Thousands of Z4 owners have reported the same issue in online forums.

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.

ELECTRICAL SYSTEM
The electrical system of BMW vehicles has been subject to an ongoing development process over the last few years. This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle âÂÂdischarged batteryâ complaints.
EQUIPMENT:ELECTRICAL
Vehicle cannot be opened or closed using comfort access, engine start is not possible, and the vehicle may not start when placing the key against the steering column.
SERVICE BRAKES, AIR:DISC; STEERING: STEERING WHEEL/HANDLE BAR
Diagnosis of Compound Brake System Complaints in M Vehicles: 1. Visible cracks are caused by high thermal stresses during rapid heating and cooling of the brake discs. Braking from high speed with cold brake components (less than 212 degrees F) increases the likelihood of cracks to form.
ELECTRICAL SYSTEM; EQUIPMENT; EQUIPMENT ADAPTIVE/MOBILITY
Discharged Battery Energy Diagnosis Must Be Performed: The electrical system of BMW vehicles has been subject to an ongoing development process over the last few years. This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle "discharged battery" complaints. In order to properly repair the vehicle the first time in the workshop, it is very important that the diagnostic test plans are performed to completion, with all results taken into consideration. Without performing the energy diagnosis test plan, the root cause of the discharged battery cannot be identified. This increases the chances of a repeat repair.
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
