2025 Hyundai Tucson

Blindspot detection did not pick up car on my right side two times. Front collision warning is effected by the angle of the sun at certain times of the day. Dashboard dims randomly. Could be for a minute or much longer. Could dim on and off, or stay dimmed for over twenty minutes. Brought the car in twice for this problem. Claimed nothing found and tech reset the codes. Bought it in two weeks later, stating problem not fixed. Told them to check connection, suggested they might want to replace the cables, and its a known problem. Again, reset the codes. Only this time they fiddled with the dimmer control on the console and I can no longer adjust the setting.

The horn on my 2025 Hyundai Tucson Limited failed without warning in mid January 2026 and no longer functions. This creates a serious safety risk because I was unable to warn another driver while they were merging into my lane on the highway. Without a functioning horn, I cannot alert other drivers to avoid potential collisions. The vehicle was inspected by Balise Hyundai in Springfield, MA, on January 23, 2026, and the dealership confirmed the horn requires replacement. However, they cannot cannot order the replacement part because it is unavailable, possibly due to a redesign or manufacturer change. Hyundai Consumer Affairs has acknowledged the defect and confirmed there is no timeline for repair. They are not allowing dealerships to order the old part and do not have a timeline on when the redesigned part will be available. Because the horn does not function, my Massachusetts State Inspection sticker is expired and cannot be renewed until the horn is repaired, making the vehicle illegal to operate. There were no warning lamps or prior symptoms before the failure. The vehicle is available for inspection upon request.

The horn in our 2025 Hyundai Tucson failed. We took the vehicle to two separate dealerships to get replaced, but were told the horns were out of stock with no ETA for parts. I followed up multiple times over several months with both dealerships, but got nowhere. This is a huge safety issue. How can Hyundai not correct this issue?

The adaptive cruise control reduces speed when the car's driver camera "senses" that driver is distracted when in fact, this occurs frequently within even a 30 minute drive: it senses "distracted driving" due to wearing sunglasses, short stature making in cab camera have difficulty seeing eyes of driver, etc. This is a frequent problem in my car and a frequent problem in driver forums. This is unsafe when it slows car without warning and is stressful. Upgrades needed for safety.

I was travelling southbound on a main urban street. I was approaching an interesting with a feeder road to a major freeway. I was in a line of cars making a right hand turn onto this feeder. Just before I was about to start turning right, the Tucson Hybrid suddenly and unexpectedly smalled on the brakes and I came to a full stop. I was HIT FROM BEHIND. There was minimal damage to the car that hit me. My car had damage to some plastic components on the bottom of my rear bumper. Total cost to repair this damage was $785. No insurance claim was filed.
