1 Equipment problem

Failure Date: 03/09/2026

In a 2020 Toyota Tundra, 1794 edition (60k miles), traveling at normal highway speed, the moonroof glass panel spontaneously exploded. There was no previous damage or modification to the moonroof panel. Panel explosion was extremely loud and surprising. Large pieces of glass were blown back onto the highway. If the shade was not drawn at this time, large amounts of glass would have also rained down onto the driver and passenger of the vehicle. Clear dash camera footage shows speed under the speed limit, and no impact from any sort of debris.

4 Equipment problem

Failure Date: 01/13/2024

Driving on the highway and the sunroof spontaneously exploded — portions of glass traveling up and out of the vehicle, with some falling into the sunshade. Skies were clear with temperatures around 25 degrees fahrenheit. There were no overpasses or other structure from which debris could have fallen, nor could it have come from another vehicle.

5 Equipment problem

Failure Date: 02/25/2023

Note: Toyota has confirmed this issue, but is unable to resolve this. When the sos button is pressed, the dcm module is supposed to send the proper VIN number and location to the call center. The call center does not receive the proper VIN number and pulls up the wrong person / location. In my case, if an emergency occurred, they would send emergency assistance to a vehicle located in another state entirely. This is not because the wrong owner is assigned to their system. They can find my vehicle VIN with the proper owner information in their system. The issue is that the dcm module (or other system) is actually sending the wrong VIN to their system. The Toyota sos call center says to see the dealer and the dealer says they are unable to fix this. If this is not isolated to just my vehicle, this could cause a loss of life if emergency assistance never arrives at the proper vehicle location.

8 Equipment problem

Failure Date: 09/17/2019

I bought 2020 Toyota Tundra 1794, black. I love this truck, but it annoy me when every time I start the vehicle and drive about 15miles/hour I hear and feel a "clunk" sound under the front drive side, and feel it on the gas pedal. I heard this sound after 5 days since I bought it, I called the dealer and set up appointment. I brought it to dealer where I bought it, they cannot fix it. That problem bothers me all the tine. I don't know that to do with it.
