I am reporting a safety defect in the 2025 Toyota Highlander Hybrid Nightshade involving the multifunction turn signal switch.

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…
