The vehicle was a private sale. The contact also stated that the vehicle was once sold at a private auction. At the time of purchase, the vehicle mileage was 158,000; however, upon discovery of the service paperwork, the contact discovered that the vehicle mileage was once 250,000.”

“Seat heater stopped working. Turns out there is a burnt connector leading to part number 87501-0C020, which appears to be a seat heater amp. One pin of the connector is completely melted. I've purchased this truck brand new from Toyota. Nobody has ever touched this part. Scared that it could have caught fire.”
“THE FRONT DRIVER AND FRONT PASSENGER DOOR LOCK INTERMITTENTLY DO NOT WORK. THERE ARE NO SPECIFIC PARTS OF THE DAY, TIME, WEATHER CONDITIONS. IT WILL WORK FINE AND THEN EITHER ONE FAILS OR THE OTHER, OR BOTH. THEN ITS STARTS TO WORK AGAIN WITHOUT ANY ISSUES. THIS HAS BEEN GOING ON FOR AT LEAST 12-18 MONTHS.”
“MY 2016 TOYOTA TUNDRA 1794 CREWMAX, DURING WINTER MONTHS IN MIDWEST - THE HEADLIGHTS AND AND INTERNAL INSTRUMENTATION WILL TURN OFF WHEN TURNING LEFT OR RIGHT WITH TURN SIGNAL ENGAGED. THE AUTOMATIC LIGHTS ARE ENGAGED ON COLUMN STALK AND THE ISSUE OCCURS AT NIGHT. THE VEHICLE IS IN MOTION”
“HEADLIGHTS TURN OFF INTERMITTENTLY WHEN THE LEFT TURN SIGNAL IS USED AND THE HEADLIGHTS SWITCH IS IN AUTO MORE. DEALERSHIP CAN'T/WON'T REPLICATE THE ISSUE SO THEY WILL NOT TROUBLESHOOT FURTHER. THIS IS A PROBLEM THAT A LOT OF PLATINUM AND 1794 EDITION TOYOTA TUNDRAS ARE HAVING AND IT IS BEING IGNORED BY TOYOTA; HTTPS://WWW.TUNDRAS.COM/THREADS/AUTO-HEADLIGHTS-SHUT-OFF-WITH-TURN-SIGNAL.22968/ HTTPS://WWW.YOUTUBE.COM/WATCH?V=2TZRPLQ9WP4 I'VE HAD IT INTO THE DEALERSHIP TO CHECK AND THEY SAY THERE IS NOTHING THEY CAN DO. PICKUP ONLY HAS ABOUT 26K MILES ON IT. FIRST TIME IT HAPPENED WAS ON A FREEWAY CLOVERLEAF IN THE RAIN AND LUCKILY THERE WERE STREET LIGHTS BECAUSE I WAS IN THE MIDDLE OF A MERGE. OTHER TIMES IT HAS BEEN SIGNALING TO TURN LEFT AND ENTERING THE CENTER TURN LANE ON MULTI-LANE ROADS. ALWAYS HAPPENS WHILE IT IS DARK OUTSIDE BECAUSE THAT'S WHEN THE HEADLIGHTS ARE IN AUTO WHICH MAKES IT MORE DANGEROUS.”
