Two problems related to starter have been reported for the 2009 BMW 328. The most recently reported issues are listed below.
The battery connections in the rear compartment have completely corroded. My mechanic has told me this is a common issue with many BMW series not just the 3 series. Water seepage appears to be a specific problem with failures to rubber gaskets in the trunk/rear lights in this convertible. The repair is $2,000. 00 as the entire cable system must be replaced to the engine an 11 hour job. This is a well known issue but not acceptable from a car that has been garaged its entire life. This should be investigated as many consumers are paying an enormous bill due to bad design, workmanship and engineering. The dx occurred after much investigation and the inability to start the car for 2 weeks after $300. 00 worth of repairs (new battery, starter, relay switch) the mechanic told me that we were lucky there was not a fire as the both main cables were arcing at the connection point.
Battery and starter all checked out. But break pedal stiffens up and car will not start. I have read on internet and watched a few videos about the same problem. How many people have to suffer and pay for Bmws problems.
