Between the hours of 11:00 a.m. and 1:00 p.m. while heading west with cruise control on and I passed a truck that was fully in the left turn lane my vehicle has done a collision avoidance complete stop three time in the same day. 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.
