NHTSA complaint #11338155, 2020 · crash

“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.”

NHTSA complaint #11518301, 2023

“Vehicle stalled and lost power at approximately 45 mph. Warning lights activated and "Not ready to drive" message was displayed. Vehicle has had 3 other similar episodes all resulting in the vehicle losing power at high speed. Vehicle was towed to local Toyota service dept. where they said it generated a code for rough idling - low fuel. They did no repairs and offered no explanation. Three miles from the dealership the Tundra died in traffic. The safety of my family was certainly at stake and had my wife been driving the vehicle she likely couldn't have steered the vehicle to safety. These ar…”

Engine 5

“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.

“TL* THE CONTACT OWNS A 2020 TOYOTA TUNDRA. THE CONTACT STATED WHILE DRIVING AT LOW SPEEDS, HE STARTED TO HEAR AN ABNORMAL NOISE. THE CONTACT STATED NO WARNING LIGHT WAS ILLUMINATED.

NHTSA complaint #11394700, 2020

“WHEN WEATHER GETS WARM (100F+), IT WILL OFTEN TAKE A FEW SECONDS TO START THE CAR. IT CRANKS OVER, BUT WON'T CATCH. WHEN WEATHER GETS TO 110F, IT WOULD FAIL TO START AFTER IT HAS BEEN DRIVEN, THEN PARKED. WAIT 90 MINUTES, AND IT WOULD STARTS AGAIN. THIS IS A SAFETY ISSUE, BECAUSE WHEN WEATHER IS 110F+, IT IS VERY VERY UNCOMFORTABLE WAITING FOR A TOW TRUCK (THEY ARE USUALLY SUPER BUSY ON A HOT DAY) OR WAIT 90 MINUTES PLUS IN 110F+ WEATHER. TOYOTA HAS REFUSED TO FIX IT, AS THEY SAY THEY NEED TO WAIT FOR A 110F+ DAY TO DUPLICATE THE ISSUE,”

Service Brakes 4 1 crash

“I was driving in a 25 MPH zone approaching a red light preparing to stop.

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…”

Electrical System 3

“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…”

“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.”
