Adaptive Cruise Control Problems of Toyota Tundra

When starting up my truck in the morning there is rough idle that cause truck to sputter and sound horrible. It eventually smooths out but I believe the computer needs flashing. When I look online some have a recall for the engine 3ur-fbe / 2018 Toyota Tundra, but when I put in my VIN # it shows no recall and throws off check engine light code. Also my radar sensor that it on for cruise control is showing up on dash please contact dealer and flashing. They have replaced this before with recall and now it’s acting up again. Also traction control is lighting up I. The dash as well blinking along with all these codes.

Advanced driving system - truck with leave a lane unprovoked and will fight you to recover manually. I have another Toyota with the same system (2024 grand highlander) and it works perfect. Not confirmed by dealer yet. It will be next week. Not inspected yet. Automatic lane centering just stops working, display changes to "not tracking'. Blue lines disappear on display. Truck has done this since new. I was very disappointed when I first used it since I expected it to work like our highlander.

Before this recall happened we had issues with screen blacking out and crashing even after the recall was “fixed” also the back seat outlet has never worked.

The car auto adaptive cruise control does not use the transmission for downhill breaking. It just rides the brakes coming down now. The car started shaking from overheating the brakes and I said realizing that it just not working in tune with the transmission. This is very dangerous. I have to turn off the cruise control and he manually downshift so break system of start working again. It was shaking so violently wouldn't stop.

The brakes failed while traveling 72 miles per hour on cruise control, and controlled distance. I was traveling behind a semi truck in the third lane from the right on interstate 5 near stockton, calif. Coming upon the truck the Tundra started to accelerate, I hit the brakes numerous times yet Tundra continued to accelerate, so I hit cancel on speed control, thru into park, and navigated three lanes left in heavy traffic into the median, still hitting my breaks, finally stopped the Tundra with emergency break, but took the right rear tire off the rim in my violent exit to the median, inspection has been complete from Toyota mfg. Saying I have a normal truck, dealer can not confirm problem, there were no warning signs. I am a very experience large animal veterinarian driving over 3 million miles in my career with no accidents, or moving violations. I own a 2007 Tundra with 200,000 miles, no incidents, I know where the brakes are on a Tundra.

Toyota safety sense (tss) malfunctions sporadically while driving. Warning lights illuminate and dynamic radar cruise control (drcc) disengages when activated while driving. The pre-collision system (pcs) is turned off and flashes with the following error messages. - pre-collision system malfunction - visit your dealer - auto headlight system malfunction - visit your dealer - lda malfunction - visit your dealer this has happened twice, first right after purchasing the vehicle brand new in 2019 and most recently last week on 5/22/2021. I took the vehicle into the dealer on 5/25/2021 and they seemed aware of this issue, but stated they could not reproduce it and there were no error codes logged. I showed them the video of this happening (link below) while driving through nevada. I was told the errors will not disable the vehicle or put it into limp mode, but my concern is when this happens while using drcc, which almost made me drive into the back of a tractor trailer on interstate 80. The speed limit on I-80 in nevada is 80 mph. Https://drive. Google. Com/file/d/1wrxgm8sjeb02eo4a6e9tbycear6grrhs/view?usp=sharing.
