2025 Toyota Sienna Hybrid

June 3, 2026, approximately 5:30 PM EDT, I entered my 2025 Toyota Sienna to move it from the street beside my home, to my driveway. Upon closing the driver's door, the rear liftgate window exploded into the vehicle. This occurred without any warning or adverse action by myself or anyone else. The vehicle has been in no collisions, and has only 6429 miles on the odometer. I phoned Toyota's "Customer Experience Center" to report the incident and to seek warranty service for this problem. I was told to drive the vehicle to my Toyota Dealer, which is located 115 miles away, for inspection. I explained that it is unsafe to drive a vehicle filled with broken glass and with no rear window 115 miles. If I vacuum up the glass, there is nothing for the dealership technician to inspect. If I tape plastic over the opening, it could come loose at highway speed, and cause an accident, and the tape adhesive could damage the vehicle finish. The Toyota agent advised me that the vehicle must be inspected at a Toyota Dealership, and if the vehicle is unsafe to drive to the dealer, we could have it towed. But in a subsequent call to the "Customer Experience Center", my wife was informed that Toyota would not cover a tow of that distance in their warranty, and it was our fault for buying a car and taking it to an area that far from a dealer. The phone number we called is located inside the vehicle owner's manual cover under a heading, "If there is not a Toyota dealer near you, please call the following number:" In the morning, once they are open, I will call the nearest dealership, 115 miles distant, to seek further guidance. Based on my background in both mechanical engineering and automotive failure analysis, it is my opinion that the window and its support system was not designed to withstand the prolonged sun and heat exposure experienced. The outside temperature reached at least 82 degrees F where the vehicle was parked.

After very minor rainfall, my rear backup camera was not usable as water was dripping off of the edge of the door handle trim and it was getting on the lens. This is a complete design problem as there should be a drip edge. You made it very difficult to properly pull up at a gas station pump and I was unable to get close to the pump because of how the lens was obscured by the water drops.

Outer rear-view mirror on the driver side exhibits a vibration/shaking of the image. It is obvious and continuous vibration is observed typically on highway speeds of approximately 60mph or higher and lower speeds it is evident driving over slight bumps, concrete/asphalt road surfaces or bridges. Looking at the shaking image cause dizziness and it is even worse in night time with headlights from vehicles coming behind. It is annoyance to the point that makes you feel not to use the rear-view which can potentially put the vehicle and others in danger. Passenger side doesn't vibrate and makes it easy to notice the issue. Dealer inspected the mirror and said manufacturing issue and replaced it under warranty with no success is fixing underlying vibration issue. On the second visit, dealer denies the problem and says the mirror is replaced and operates according to toyota specification (it feels to us they do not care about the functionality). According to dealer they will do anything further only if Toyota release a TSB on this particular issue.

The drivers side exterior mirror shakes. This occurs during all driving, most notably over bumpy roads and at highway speeds. The passenger side mirror does not have this problem. Because of the shaking, it is distracting when driving as it appears there is movement in the mirror. Additionally, it causes a distortion from the constant movement. The vehicle was purchased in June 2025 and has occurred since day 1. The vehicle was in the dealer on 9/30/25 and noted the issue, stating there is nothing physically wrong with the mirror but did agree with the assessment. They said this is common on vehicles (they see the complaint a lot) but Toyota has not acknowledged it so there is no fix and appears to be a manufacturing defect.
