All electrical power has been shut off to vehicle on 4 different occassions. The first time was while entering a right turn lane at a slow speed. All power equipment failed. . . No power brakes, no power steering, etc. I was able to restart the engine without difficulty after turning the ignition off (with the transmission in neutral) and starting in a normal fashion. This failure mode and resolution is typical. The second time, I was turning left across a fairly busy intersection. Fortunately, I had enough momentum to continue without being hit by oncoming traffic. The third time was in an enclosed parking lot as I made a slow right turn to go up a ramp. The fourth time, and this one was unusual, I was travelling about 45 mph when all the failure lights came on for about 1 sec. Fortunately, the power came on by itself. Imagine the consequences of a total electrical failure at 40+ mph in traffic. . . No power to the brakes or steering. Ts.
