2 Alternator/generator/regulator problem

Failure Date: 01/20/2015

I've replaed the window regulators in my car several times due to the material being cheap. The gears wear out and/or break apart. Each time it's between $150 and $300 to repair. The window stops half-way down and can't be moved. This presents issues with safety during inclement weather and makes it very easy to get into the car to take valuables and potentially steal the vehicle.

BMW 3 series (e36-e46) 1991-2005 window regulators break constantly.
