The microphone has an issue and it is tied to the SOS call button in the car. I asked my dealership, they wanted to charge $200 to run a diagnostic scan, I contacted Toyota directly, they basically said the dealer can charge it if they want and reverse the charge if they find a problem under warranty. I originally thought the issue was with the Blue Tooth. I found this video on YouTube, his fix did work-my concern is, if I had needed Emergency help-the button would not have called anyone, disconnecting your car battery is NOT something I should I have to do to fix a 2019 vehicle. https://www.youtube.com/watch?v=FkAdMRKHS_0
The contact owns a 2019 Toyota Sienna. The contact stated that the liftgate failed to lower while using the remote. While reversing, the back-up camera became inoperable. The air bag warning light was illuminated. The vehicle was taken to the local dealer who stated the failure was due to the remote start feature that was installed. The vehicle was not diagnosed or repaired. The contact stated that she noticed the mirrors were fractured. While driving at an undisclosed speed, several unknown safety features became inoperable. There was a burning odor detected inside the vehicle. The manufacturer was contacted and offered to pay a nominal portion of the repair for the mirrors and referred her to the NHTSA Hotline for assistance. The approximate failure mileage was 72,000.
THE FIRST WEEKS SEEMED LIKE EVERYTHING WAS FINE WITH THE VEHICLE UNTIL WE STARTED FEELING LOW LEVELS OF ELECTRICAL SHOCKS. IT WAS MOSTLY ON THE STEERING WHEEL SO WE THOUGHT THAT THE SENSATION WOULD GO AWAY, BUT IT ACTUALLY STARTED GOING WORSE TO THE POINT THAT WE STARTED HAVING DISCOMFORT ON THE SEATBELT AND THE LAST THREE WEEKS BEFORE WE DROPPED THE VEHICLE AT THE DEALERSHIP THE HAZARD STARTED TO INTENSIFY AND GET STRONGER. THE SEATBELT OF THE 2019 TOYOTA SIENNA HAD PROVIDED A LOT OF PAIN TO MY OVARIES (TO THE POINT THAT MY PERIOD HAD BEEN ALTERED DURING THE MONTHS OF OCTOBER TO DECEMBER 2019), IT CAUSED SO MUCH PAIN IN MY STOMACH WHILE BEING A DRIVER AND A PASSENGER SPECIALLY THE LAST THREE WEEKS BEFORE I DROPPED THE VEHICLE AT THE DEALERSHIP. ALSO DUE TO THE FACT THAT I AM FIVE FEET TALL, THE SEATBELT RESTED ON MY NECK WHICH WAS THE MOST UNCOMFORTABLE EXPERIENCE. IN THOSE PAST THREE WEEKS PRIOR TO DROPPING IT AT THE DEALERSHIP, I EVEN FELT SHOCKS FROM THE SEATBELT WHILE IT WAS RESTING ON MY NECK CAUSING NUMBNESS IN MY LEGS. ON REGARDS OF THE STEERING WHEEL, I FELT ELECTRICAL SHOCKS THAT CAUSED TINGLING IN MY HANDS GOING ALL THE WAY UP TO MY ELBOW CAUSING PAIN ON MY ELBOWS (HAVING GREATER DISCOMFORT ON MY LEFT ARM AS I TENDED TO DRIVE MOST WITH MY LEFT HAND) AND MAKING MY ARMS FEEL TINGLING AND EVENTUALLY NUMBNESS.
