Open the full vehicle complaint log (all categories)IN 2017 I WAS REPORTING THAT THE LEFT BRAKE LIGHT WAS WORKING INTERMITTENTLY. IN 2018 THE SOCKET ASSEMBLY COMPLETELY FAILED AND WAS TOLD THAT THIS WAS NOT AN EXTENDED WARRENTY REPAIR (MILAGE WAS LESS THEN 100,000). IN MARCH 2021 THE BAKE LIGHTS FAILED AGAIN. THE DEALERSHIP REPORTED THAT THE FAILURE IS INTERMITTENT BUT THAT THE SOCKET ASSEMBLY NEEDS TO BE REPLACED.
DECEMBER 2014, FOUND MY DRIVER'S SIDE TAIL LIGHT AND BRAKE LIGHT OUT. REPLACED THE BULB TWICE; DID NOT WORK. REPLACED THE FUSE; DID NOT WORK. TOOK IT TO THE LOCAL DEALERSHIP IN MARCH 2015 WHICH FOUND THE TAIL LIGHT HAS AN "EXCESSIVELY HIGH VOLTAGE" WHICH CONTINUES TO BURN OUT THE BULB. THE REPAIR WAS TO REPLACE THE ENTIRE DRIVER'S SIDE TAIL LIGHT ASSEMBLY AT A COST OF $290. THERE WAS NO RECALL OR TSB SO REPAIRS CAME OUT OF POCKET. THIS IS AN EXTREMELY DANGEROUS CONDITION THAT COULD HAVE RESULTED IN A FIRE. THIS VEHICLE IS DESIGNED TO HOLD MULTIPLE PASSENGERS, OF WHICH MY TWO CHILDREN OFTEN ACCOMPANY ME. I'M NOT SURE HOW SAFE IT IS TO DRIVE EVEN AFTER THE REPAIR. *TR
THE SATELLITE RADIO ANTENNA HAS FAILED. IT ONLY RECEIVES A SIGNAL WHEN VEHICLE IS STATIONARY. THIS APPEARS TO BE A COMMON PROBLEM WITH TOYOTA AND LEXUS OWNERS, BASED ON CHAT BOARDS. THE DEALER "FIX" RUNS OVER $1000, AND INVOLVES REPLACING THE ENTIRE LENGTH OF ANTENNA HARNESS; UNDERNEATH HEADLINER.
