2006 LEXUS LX Electrical System Problems

I LEASE A LEXUS 400H AND HAVE JUST YESTERDAY BEEN INFORMED THAT IT IS A DRIVE BY WIRE VEHICLE WITH NO MECHANICAL LINKAGE BETWEEN THE STEERING WHEEL AND THE FRONT TIRES. I AM A HAM RADIO OPERATOR AND UPON TRANSMISSION THE STEERING WHEEL SHAKES. NO AMOUNT OF FILTERING OR OTHER MEASURES HAVE ALLEVIATED THE PROBLEM. I BELIEVE THAT THE CAR IS INHERENTLY DANGEROUS AND WOOULD NEVER HAVE LEASED IT IF I HAD KNOW THAT IT WAS A DRIVE BY WIRE VEHICLE. NOTE THAT THERE ARE A LARGE NUMBER OF RF SOURCES SUCH AS BROADCAST STATIONS, TV STATIONS, MICROWAVE LINKS AND AIRCRAFT RADARS THAT WOULD AFFECT THE STEERING OF THIS VEHICLE. MOREOVER, IT DOES NOT APPEAR THAT THIS HYBRID MEETS THE FCC EMI STANDARDS. PLEASE INVESTIGATE.
