“Today I had a crash and luckily walked away. I went down an embankment at speed into trees where the vehicle rolled and struck trees head on. All the vehicle airbags deployed and vehicle came to rest on the drivers side. Although there was electrical power and the engine still running none of the right side doors would open and neither would the rear hatch which was clear of obstruction!

This failure mirrors Toyota Safety Recall 20TA02 (NHTSA Campaign 20V012) for the exact same model year 2017 Toyota Sienna, but my specific VIN is currently excluded from the recall list. The un-recalled defective component created an immediate highway safety hazard as me and my family were left stranded in the middle of the road. We waited for hours at the risk of oncomi…”

“EXCESSIVE TIRE WEAR ON OUTER EDGES. TIRES WERE ROTATED EVERY 5,000 MILES OR SO, AFTER 20,000 TIRES WERE VERY WORN. REPLACED AT 30,000, WHICH WAS ACTUALLY WAY PAST WHAT WAS SAFE FOR THEM. NOW, WITH MICHELIN DEFENDERS, AN ALIGNMENT UPON INSTALLATION (WHICH DID NOT SHOW ANYTHING), AND PROPER TIRE PRESSURE AT 4500 MILES, SAME WEAR IS HAPPENING. TOYOTA'S RESPONSE WAS THAT IT IS A HEAVY VEHICLE. WHAT IS IT: TIRES ARE FALSELY LABELED FOR HIGHER MILAGE THAN THEY GET OR ARE THE SIENNA TIRES NOT THE APPROPRIATE SIZE FOR THE WEIGHT OF THE VEHICLE? ATTACHED PHOTOS: FRONT WEAR AT 4500 MILES AS C…”

Back Over Prevention 1

“Wire harness section which controls the Parking Collision Warning and Rear Cross Traffic Warning is frayed, causing failure. This failure was determined by the dealer to be caused by mud packing into the rear bumper cavity. Dealer wanted over $1,000 to fix. Denied warranty, due to the cause being "an outside influence". There is no way to effectively wash the inside of the bumper without removing the bumper. If I pay for a new wire harness, the issue will re-occur. This poses an elevated risk to my family and any occupants of the vehicle, as key safety features must be disabled.”

Visibility/Wiper 1

“ON FRIDAY, 2/10/17, OUR 5 MONTH OLD SIENNA WAS DRIVEN INTO OUR SECURE GARAGE AND PARKED. NOTHING WAS OUT OF THE ORDINARY.
