Warnings problems of the 2021 Toyota Highlander

The vehicle experiences intermittent power steering malfunction while driving. Warning messages including “power steering malfunction” and “low voltage abnormality” appear, and the steering wheel becomes stiff and difficult to turn. This has occurred multiple times during normal driving conditions, including at low speeds and while turning. When the issue occurs, it requires increased effort to steer, creating a risk of loss of control. Additional warning messages have included awd malfunction, pre-collision system malfunction, and lane tracing assist malfunction. These alerts appear simultaneously with the steering issue. The problem began shortly after purchase and has continued intermittently. The vehicle has been inspected, but the issue has not been resolved. This condition creates a safety risk, especially when driving with passengers.

The rear cross traffic avoidance does not detect a person on a bicycle or motorcycle. The safety sense 2. 5 + was advertised and demoed to detect even a pedestrian walking behind the vehicle. The system on my vehicle does not work as advertised and after taking my vehicle to the dealer was informed by the service manager that the system is "intermittent at best". This is not what Toyota advertises. Dealerships apparently have no signal strength detection equipment to verify proper operation of this system. I have reviewed multiple videos of this system in operation and there were no indications of intermittent failures. I have contacted Toyota customer support and am being ignored.
