   When driving on the freeway at 70mph speeds during rush hour, I lost all power to the vehicle causing me to have to immediately pull to the side of the freeway with minimal control of the vehicle. I had to come to a complete stop on the freeway putting myself and others at high risk for a high speed crash. There were no warning lamps just a full system failure. There are recalls on certain VIN numbers for the Denso Low Pressure Fuel Pump and a class action lawsuit settlement that resulted in Customer Support Program 23TE05 but when I called Toyota they said my VIN did not qualify.

I wasn’t tailgating and I was doing the speed limit of 55 mph. The road was very straight. It did this twice before about a year ago. I reported it to the dealer and they could find nothing wrong with my vehicle.

   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.

    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.

    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.

    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??????

    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.

    The headrests on the seats slip out of place very easily. It is available for inspection on request. In case of accident, the headrests may fly off the seat very easily, with failure to prevent whiplash injury. The problem has not been confirmed by a dealer or service center. The vehicle has not been inspected by anyone but me, the owner. There are no warning lamps, messages, or other symptoms of the problem. The problem was there when I bought the vehicle in 2022.

    This has happened twice now. 1st occurs on the DC beltway in VA HOV lanes, outer loop just past Tysons Corner while going 70+ MPH in the lane with no vehicles around the collision warning system and break automatically alerted , sensor indicated and dash board flashed BREAK. It resolved on its own. This was in august on a hot sunny day, no rain, no fog. The second occurrence just happened two weeks ago. It was sunny, 55-65 degrees, 35-49 PMH approx 3 vehicles back while turning south from rote 27 in mount airy maryland onto Penn shop road, the vehicle did the same thing. Indicated I was going to crash, applied the breaks automatically and almost caused an accident with a vehicle traveling behind me. First time I thought was a fluke- second time- no. Will be sending to dealer. Vehicle has less than 25k. 2020, Calvary blue, 4x4, shortened, crew max.
