Wiring Problems of BMW 540

My check engine light came on for chassis stabilization and drivetrain malfunction. I took it to the dealership and they told me they repair would not be covered under warranty. Dealership alleges a rodent gnawed on a engine wiring harness. From what I gather from the dealership this occurs frequently. The manufacturer is aware of this problem but has failed to make necessary design changes to make these wiring harnesses inaccessible to rodents. My case is not the worse case scenario but a fire could have started, my vehicle could have become inoperable and cause an accident while operating the vehicle. I would like to request fmvss be updated to address these product design defects. A wiring harness that can potential disable regular functions of the vehicle could result in death should not be easily disabled by a rodent.

I have a 2001 BMW 540ia (VIN wbadn63441gm73054) and all the external lights are gradually failing. In all cases the lights bulbs are ok. First the passenger side rear turn signal light failed, then the drivers side daylight running light, then the passenger side reversing light, then the passenger side brake light, then drivers side high beam, then the drivers side front turn light etc. Failures were over approximately a 2 week period. The most disturbing thing is the onboard computer is showing all the external lights working correctly. My BMW mechanic tells me the fault is in the onboard light control module (lcm). I consider a failure of this nature to be completely unacceptable in a 4 year old vehicle and a serious safety defect that has the potential to result in an accident. I have reported the problem to BMW na, so far they are not interested in investigating the problem.
