2018 Lexus LS ELECTRICAL SYSTEM,UNKNOWN OR OTHER

THE COLLISION AVOIDANCE SYSTEM BLOWS FUSES AND STOPS WORKING, BUT THE LIGHT ON THE DASH CONTINUES TO INDICATE THAT EVERYTHING IS WORKING. IN OTHER WORDS, THERE IS NO WAY TO LEARN THAT THE COLLISION SYSTEM IS OFFLINE UNLESS YOU'RE WILLING TO SIMULATE A NEAR CERTAIN COLLISION (WHICH I DID WITH THE DEALER IN MY CAR AND HE FINALLY ACKNOWLEDGED THE PROBLEM), OR HAVING AN ACTUAL ACCIDENT. THIS IS CLEARLY A DESIGN FLAW. IF THE FUSE IS BLOWN, OBVIOUSLY THE SYSTEM SHOULD SHOW AN ERROR WHEN IT'S ENGAGED - NOT A GREEN INDICATOR.
