03 Computer problem due to land radar
 

Have a 03 Expedition. On recent trip to Knoxville gauges, windows, msg. center went dead. Motor continued to run a AC worked. Took it to Kirksville ford dealer and they told us doppler complex up the road caused the computer to lose codes etc. They said this only happens to 03's.They did fix the problem and routed us around the radarsite. Has this happened to anyone else? Can anything be done to prevent this in the future or is this a pile of crap from Ford??
