I am reporting a safety defect in the 2025 Toyota Highlander Hybrid Nightshade involving the multifunction turn signal switch. The interior trim adhesive on the steering column has experienced a chemical breakdown (adhesive migration), causing the turn signal stalk to become stiff and bind. This obstruction makes it difficult to engage the turn signal and occasionally prevents the signal from "auto-canceling" after a turn. The dealership has acknowledged the adhesive failure by authorizing the replacement of the steering column covers but refuses to replace the contaminated turn signal switch. Operating a vehicle with a binding turn signal switch is a direct safety hazard, as it compromises the driver's ability to communicate intent to other motorists. Additionally, the dashboard material is experiencing systemic delamination and producing a white crystalline powder (crystallized adhesive). I am requesting an investigation into the heat-resistance standards of the interior bonding agents used in the 2025 Nightshade trim, as these materials are failing and compromising safety-critical electronic controls.

While waiting for a traffic light to change, I pressed the pedal to accelerate, and the car would not move. Like my pedal was dead. I have experienced this issue three times. I have also experienced bucking or jerking issues.

Passenger seat belt won't extend half of the time. We have tried with engine on or off, put it in park and in gear, door open or closed and every other trick. We have pulled the belt straight up and down and every other angle. We have adjusted the height for tall or short riders. We took to the auto dealership, and they said it would not work for them at first then it started to work. We have had riders in the passenger front seat ride with no seat belt on because they couldn't extend it and gave up. It should work every time there because it is a safety issue that should be fixed.
