2020 Toyota Tundra problems

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

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.

UNKNOWN OR OTHER

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.

STRUCTURE:BODY

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.

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.

ENGINE

Air conditioning compressor partially seizes if air conditioning is turned on while driving and when air conditioning knob is on at time engine is started. Makes very loud noise. When driving, and it occurs, truck will slow suddenly as if the brakes were applied until compressor engages. Dealer mechanic says it sounds like the compressor clutch engaging. Said nothing wrong. Have left truck with dealer several times and they say they cannot replicate the issue. I’ve recorded the sound several times and have played that to them. They hear it but say that they have to prove that is what is happening. They refuse to replace the compressor. Vehicle is not safe to drive when this happens. This has occurred since truck was purchased brand new.
