The contact owns a 2025 Toyota Highlander. The contact stated that while she and her husband were driving at 60 MPH, she heard a loud explosion noise from above her head and felt air whipping on top of her head. The contact stated that the sunroof exploded; however, the sunroof shield prevented the glass from entering the vehicle. The vehicle was steered to the side of the road and inspected, but the contact did not find anything wrong at that time. The vehicle was taken to a dealer where it was diagnosed that a rock may have hit the sunroof. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 8,498.

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.

The speedometer registers speed up to 7mph over actual speed for the first 15 miles then returns to matching GPS speed. Reported to Toyota, dealer said they have seen this before but not identified a fix as of today

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.
