Blind Spot Detection problems of the 2023 Toyota Highlander

Blind spot feature is detecting a vehicle two lanes over from the lane I’m driving on. This has caused to almost result in a crash due to this safety hazard. Blind spot is always detecting a vehicle driving two lanes over. Blind spot signal on driver mirror flashes as well when such vehicle two lanes over is detected and I am about to move over to my adjacent lane.

The warning lights go on for no apparent reason. Dash instrumen just disappear for no apparent reason and then reappear randomly. Such as compass disappearing and reappearing throughout the drive at long stretches at a time. The forward and rear collision warning system just come on when nothing is close to vehicle. The blind spot monitoring system doesn’t always show up on right side of vehicle. Doesn’t matter speed or road conditions. It randomly happens throughout our regular commute and not. The warning buzzer goes off but doesn’t say what is the problem. Went off for over half an hour even when car was stopped and car turned off. Dealership not able to figure out why. Said to bring it in while doing it. By time I get there it’s done. I live 1/2 hour away. They drive it and say blind spot working like supposed to. I showed them videos of how it’s not working and they tell me it’s fine. Yet even a semi truck didn’t show up in blind spot or a ups truck. They say unless it throws a code every thing is fine. Yet I’ve had clear roads, no rain no traffic nothing and had my collision warning lights and sounds go off and not stop for up to 5-10 minutes.

The right side blind spot warning does not always show a vehicle is in blind spot. The forward collision will alert will start and keep beeping for up to 3 minutes when nothing is in the area. I pulled into driveway and the vehicle started to beep a warning but no warning message showed up on dash. It continued for 30 minutes even after I turned off car. Then started it and drove it a mile and parked it again. I get on the overhead view a generalized warring. But doesn’t say what it is then goes away. This has happened a couple of times when driving. All doors shut, all seat belts locked if someone is in seat, it starts after driving for some time. No apparent reason it starts and stops but is a hazard if trying to drive and figure out why it’s beeping like something is wrong. I also have paint chipping off back bumper on the top for no apparent reason. The back liftgate doesn’t always close even when nothing is in the way. It doesn’t always open when you push the button the first time. The crossbars for luggage installed by Toyota does not keep end cap on on drivers side front and I had to pay to get new ones. The problem is the rail does not hold the cap tight.
