Open the full vehicle complaint log (all categories)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
Pre collison warning system has turned itself off in the rain and states visit dealer for service. Never logs data and on when you get to dealer. Same system has also flash "Brake" on the highway at 65 mph when a dry sunny day and no cars around. I am worried it may actually brake by accident causing loss of control. Went to dealer on both occasions and because it doesn't log the data there was nothing they could do. Did my own research and there was a technical service bulletin for certain VINS (not mine) to "repair" this module behind the grill. It was done to my truck but not by my dealership before I took ownership. It should not have been done and Route 44 toyota just did nothing. I asked for a replacement and they wouldn't because there wasn't any codes listed to warrant it because the TSB wasn't for my truck even though someone did it. On their TSB it recommends replacement for my current issues but they wouldn't do it.
