Driving in a storm all the forward looking sensors failed as the sensor became covered with snow and ice. These are the sensors that control collision alert, lane departure alert, cruse control etc. The safety functions most required in bad weather failed.

While turning right from one street to another, there was complete engine shut-off, and several seconds passed before I could re-start the car, this occurring in morning rush hour, and barely averted an accident. This car also has had numerous random and occasional electrical problems, mirrors moving on their own, garage opener not working, seat memory not working, etc. Shop can't duplicate them and therefore cannot fix. Lexus does not respond. Worry is that engine cut-off might happen again, and also worry that there is an overall electrical problem that affects major systems, including engine operation.
