Starter Solenoid problems of the 2009 Volkswagen Routan

*sometimes the vehicle will not start for no apparent reason. Vw service dept. Cannot detect an issue. *engine light comes on intermittently while driving-vw cannot detect anything wrong. * alarms go off but no signal showing on the dashboard. *power windows and seats work intermittently- *found vehicle's sliding door wide open I parking lot, twice. * have also found windows open. Our lift gate (trunk) opened while driving on the highway. * vehicle failed to shift,while driving, revved and would not reset until pulling over and turning off the vehicle. Though vw could not find faulty readings and didn't believe tipm is the issue because they couldn't read it. Being familiar with programming, I know that glitches can cause faulty readings. If there is a glitch before the reading can be processed by the computer, there will be no faulty reading logged. A pc won't save a file, either if the power supply is interrupted before it can do so. . Tipm malfunctions can also cause all other issues I have experienced. Upon getting a second opinion from transmission specialists, they said only the solenoid was faulty. They also confirmed that a faulty tipm box will cause solenoid issues and eventually ruin the new one, too. *recently, all locks stopped working & the vehicle can only be opened & locked manually. At the same time all interior lights were on and had to be turned off at the dashboard- this would have drained the battery had it happened on a work day. Vw has had the vehicle for 2 full days and yet doesn't know what's wrong with it. We have had these issues and useless repairs for over 2 years. All issues point to faulty tipm (manufactured by Chrysler, who had to settle in a lawsuit about the tipm box/ faulty relay issue for Jeep, Dodge, and Chrysler). We need help with these issues. Too many of us have it 2011 and 2012 models as well. Please help.
