Computer Failure problems of the 2005 Chrysler Town & Country

Instrument cluster lights all go on, then the gauges stop working, the trip computer stops fails, the lights flicker high to low or low to high beam and can't be changed sometimesthe engine stops running while travelling down the road at 25-75 mph! the first indicator seems that the air bag light comes on as being "off". Sometimes the lights & gauges go back to notmal. A guaranteed short-term fix is to remove the battery to reset the battery button under the battery, or take the positive terminal off & ground it against an exposed bolt. Many seem to have been fooled into buying a new battery, only to have the same problem re-arrise, inadvertantly "fixed" when the a new battery, but just lifting the old battery a little would have done the same short-term trick. The sequence of failure seems to be (rain influenced?): air bag light comes on, lights flicker, all guages & gear position indicators light up, speedo & tach pulse then fail, then you can just drive with all warning lights lit -no tach or speedo. . . Then every thing resets in 10 seconds to 10 minutes, or, dash lights go out then the engine quits, leaving you driving a powerless rolling brick in traffic, fighting the steering wheel without power steering, having only inertia (if you are Smart enough to have thrown the van into neutral) to coast off the road, through an intersection, etc. Our dealership's diagnosis was a "bad instrument cluster" - hardly, as I don't see how disconnecting the battery will instantly "fix" the instrument cluster for a while, or how the cluster will affect switching between high & low beams, or kill the engine after a sequence of events. This is a well know progressively dangerious problem, of failure leading to sudden loss of power. There are many, many electrical complaints relating to electrical failures regarding loss of functionality and engine power.

Headlamps go off intermittently. Movement of headlamp switch will turn them back on, but, interior lights are dead when opening door and overhead computer is dead when lights are on. Dangerous situation for the headlamps as it could cause a wreck. Reading online blogs this seems to be a bad problem with the 2005 model year Chrysler town and country's and Dodge caravan's. Does someone have to get killed first to warrant an NHTSA investigation? I did a search on investigations for my vehicle year and type and only found the air bag investigations. This is a very common issue with not only my year but other years of Chrysler Mini-vans. It needs attention!.
