2017 LEXUS RX HYBRID Electrical System Problems

TL* THE CONTACT OWNS A 2017 LEXUS RX450H. THE CONTACT STATED WHILE DRIVING AT VARIOUS SPEEDS, THE MAIN DISPLAY SCREEN WENT BLANK AND WOULD NOT FUNCTION PROPERLY. THE CONTACT ALSO STATED THAT ONCE THIS FAILURE OCCURRED, THE SAFETY FEATURES IN THE VEHICLE WOULD DISENGAGE AS WELL. THE CONTACT STATED NO WARNING LIGHT WAS ILLUMINATED. THE VEHICLE WAS TAKEN TO VALLEY LEXUS (4701 MCHENRY AVE, MODESTO, CA 95356) WHERE IT WAS DIAGNOSED WITH THE SCREEN NEEDING TO BE REPAIRED OR REPLACED. THE VEHICLE WAS REPAIRED HOWEVER, THE FAILURE RECURRED. THE CONTACT RELATED THE FAILURE TO AN UNKNOWN RECALL. THE MANUFACTURER WAS INFORMED OF THE FAILURE AND REFERRED THE CONTACT TO A LOCAL DEALER FOR ASSISTANCE. THE FAILURE MILEAGE WAS APPROXIMATELY 40,000. *DT

WHILE DRIVING, VEHICLE'S COMPUTER SYSTEMS SEEMED TO SHUT DOWN ENTIRELY. THESE INCLUDED THE MULTI-INFORMATIONAL DISPLAY IN THE INSTRUMENT CLUSTER AND THE PRIMARY INFOTAINMENT DISPLAY IN THE CENTER. VEHICLE'S PARKING SENSORS, ADAPTIVE CRUISE SYSTEM, AND INFOTAINMENT ALL WENT OFFLINE. THE SCREEN WENT BRIGHT MAGENTA AND THEN COMPLETELY SHUT DOWN. VEHICLE WAS ON THE HIGHWAY DURING THE INCIDENT IN DENSE TRAFFIC WITHIN THE BAY AREA OF NORTHERN CALIFORNIA. CAUTIOUS MEASURES WERE TAKEN, AND AFTER EXITING THE HIGHWAY AND FINDING A REST STOP, VEHICLE WAS SHUT DOWN AND REBOOTED 3X BEFORE SYSTEM CAME BACK ONLINE.

I RECENTLY INCURRED A A $2900 REPAIR BILL FOR RODENT DAMAGE TO MY KNOCK SENSOR WIRE HARNESS ON MY 2017 LEXUS RX 450H. (MILEAGE 13,000). IT WAS NOT COVERED UNDER WARRANTY. THE WIRING INVOLVED HAS A SOY BASED COATING. THIS COATING MAKES IT A FOOD SOURCE FOR 'CRITTERS '. THE REPLACEMENT WIRING HAS THE SAME COATING MAKING THE CHANCES OF THIS HAPPENING AGAIN EXTREMELY HIGH. THE CAR IS GARAGED WITH PERIODS OF OUTDOOR TIME. WHEN I ASKED THE SERVICE MANAGER HOW TO PREVENT THIS FROM HAPPENING AGAIN I WAS TOLD TO SPREAD MOTHBALLS ON THE DRIVEWAY AND GARAGE FLOOR AND TO STUFF BOUNCE DRYER SHEETS IN THE ENGINE COMPARTMENT. SERIOUSLY!!!! NEEDLESS TO SAY I AM CONCERNED ABOUT THIS HAPPENING AGAIN. HOW MANY OTHER LEXUS/TOYOTA OWNERS HAVE EXPERIENCED THIS PROBLEM? I WOULD HOPE THERE WOULD BE A BETTER SOLUTION THAN MOTHBALLS AND DRYER SHEETS. LEXUS RESPONDED WITH AN 'APOLOGY ' BUT...
