NHTSA Complaint #11682691 — 2025 HYUNDAI TUCSON HYBRID

On long road trip from TX to MA Started before dawn and route initially [XXX] . With sunrise route was into sun and so I used my sun glasses. Within a few minutes a warning gong and light on instrument panel litup. I did not know what the cause was and then unannounced the Adaptive cruise control lane holding and steering shut off and the vehicle seemed to brake quite vigorously. There were a few cars behind me and due to my vehicle suddenly slowing down they had to brake unexpectedly. They then honked at me and passed quite aggressively and gesturing their displeasure with me. I called hyundai tech support they where of no help. I asked for a manager - who called back and I was told it is because I used my sun glasses! I was told it would always happen if sunglasses where used and I could not cancel this feature without disabiling the "safety" features that i considered when purchasing the vehicle on 24th [XXX]. I was told I should not use polarized glasses which my pair Is Not in any event. I requested to speak to a more senior rep and the next day received call from a hyundai rep who stated there was nothing I could to over come this nuisance feature and if I didnt like it I should not have bought the car. I stated I did not know this could or would happen ! In addition every 5 to 10 minutes a warning gong,light and speech notice keeps on popping up and states "I need a rest". In my opinion too, It is also a safety issue as it is a nuisance and consistant and at inopportune times blocking gps commands some times etc. These features, in my opnion, are too frequent too persistant and not helpful. There should be a way for the owner-drver too disable the announcements but have the benefit of the features ie Adaptive Cruise Lane and Steering etc without the car deciding not to allow because sunglasses are needed. That does not enhance safety in my opinion. In my opinion the way it is programmed it is a safety hazard Just suddenly slowing down INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMA
