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.

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,

I bought a new 2020 Toyota Tundra 4X4 crewmax and it is not perform to what a V-8 powertrain of 5.7 lt, and 381 horse power should be. The accelerator on this 2020 Tundra is not functioning properly. It will not accelerate when I step on the gas pedal, which almost stall before it moves. In addiction, I owned a 2007 Tundra 4X4 crewmax and there was not a single acceleration problem. The VIN# for my new 2020 Tundra crewmax is: [xxx]. I believe Toyota has installed the accelerator incorrectly or their fuel pump is not working properly on this new 2020 Tundra models.
