| Sep 2024 | STRUCTURE | The sunroof shattered while driving down the freeway. No vehicles near or overpasses near. The shade was closed so the glass fell on it not on my head or passengers that could have been present. Sounded like a loud pop. Then I heard wind noise. The glass is blown upward, not downward. I am 40 year auto technician and own my own shop. Its my personal truck I bought new. Has never had any issues at all. This is a defect of some sort. My thought is, since I never use it. The seals aroung the glass bound in the roof opening, thus binding it where it finally flexed and shattered. | Crash: No Fire: No | Unknown |

| Dec 2023 | SERVICE BRAKES | I was driving in a 25 MPH zone approaching a red light preparing to stop. I had increased the pressure on my brake pedal and then my foot slipped of the pedal just seconds before I ran into a truck that was stopped at the red light. After further investigation I found out that the brake pedal pad has been substituted by Toyota Manufacturing. My 2020 Tundra was purchased new and has 8,800 miles on it. The petal pad is made from a PVC plastic material as stated on the bottom of the pad. There are no part #s on the pad which is suspicious that this is not a Toyota pad. The PVC material is very slippery, especially if the surface was wet. Come to find out that my 2023 RX 350 has the same brake pad. Both of these pedal pads will be replaced immediately from Toyota. Please Note. I could not upload any of the documents that you had requested. Something is corrupted with the web page that asks for upload files?????? | Crash: Yes Fire: No Towed | Unknown |
| Apr 2023 | FUEL/PROPULSION SYSTEM | Can not fuel truck normally. Gas stops pumping after 2secs and have confirmed the issues with multiple gas stations. | Crash: No Fire: No | Unknown |
| Mar 2023 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER | 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. | Crash: No Fire: No | Unknown |

Makes very loud noise. When driving, and it occurs, truck will slow suddenly as if the brakes were applied until compressor engages.
