2025 Toyota Highlander Complaint Log

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.

The contact owns a 2025 Toyota Highlander. The contact stated while driving at an undisclosed speed, there was an abnormally strong odor entering the cabin of the vehicle through the vents. The windows were rolled down due to the obnoxious odor. The vehicle was taken to the dealer and the contact was informed that the vehicle was tested for leaks in the exhaust; however, no leaks were found. The contact was informed that the fumes were possibly from burning wires or a new vehicle odor because the vehicle was a brand-new vehicle. In addition, the contact was offered the option to trade the vehicle in for a new vehicle. The contact stated that the odor was extremely strong and foul, and the odor stuck to clothing and the contact’s skin. In addition, the contact described the odor as an old lawnmower or snow blowing odor. The contact was advised by the state Attorney General Office of Illinois to contact NHTSA Hotline to report the failure. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 100. The VIN was not available.

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.
