2019 Toyota Sienna Electrical Problems

Your liftgate remote stopped working, and your backup camera went out while reversing. Your airbag warning light came on, and you noticed your side mirrors were cracked. You also detected a burning smell inside the vehicle, and several other safety features became inoperable while driving. The dealer blamed an aftermarket remote start system that was installed on the vehicle. Fixing this will likely require diagnosing the electrical system for damage or faults caused by the aftermarket remote start installation, and possibly replacing or repairing the liftgate actuator, backup camera, mirrors, and checking for any wiring issues causing the burning smell.

Your car's microphone, which is connected to the SOS emergency call button, isn't working properly. You discovered a YouTube fix involving disconnecting your car's battery, which temporarily resolved the issue—but this is an unreliable solution for a 2019 vehicle. If you'd needed emergency assistance, the SOS button might not have connected you to help. Fixing this likely requires diagnosing the microphone or SOS system electrical connection, possibly at a dealership.

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.
