2024 Toyota Grand Highlander: screen or infotainment failure

Filed Oct 30, 2026 · Electrical, Steering · TX

While driving on highway with wet roads, the steering suddenly seemed to pull to the right causing the vehicle to lose control and spin finally hitting the side barrier. I then noticed that the steering wheel was no longer aligned with the vehicle (photo attached). A few minutes prior I had an issue with the main console/radio unit and had to reboot as no sound was working. This leaves me to believe there was some type of electrical malfunction with the vehicle.
