2025 Hyundai Tucson Speed Control & Cruise Problems

Component or system that failed or malfunctioned: The electronic throttle control system and/or the powertrain control system malfunctioned, causing the vehicle to accelerate automatically and involuntarily. How safety was put at risk: The malfunction caused a collision with another vehicle and a structure. The failure placed the safety and physical integrity of two individuals at serious risk. Problem reproduction or confirmation: To my understanding, the issue has not yet been reproduced or confirmed by a dealer or an independent service center. Inspection of the vehicle or component: The vehicle and/or the affected component have not yet been inspected by the manufacturer (Hyundai), law enforcement, or insurance representatives, as an insurance claim is currently in progress. Warning lamps or prior symptoms: There were no warning lights, messages, or other symptoms prior to the failure. The incident occurred suddenly without any prior indication. During the event, the brake pedal did not respond.

The Forward Attention Warning system performs erratically, frequently disabling the adaptive cruise control without warning. Even when it does emit a warning, which again, is erractic, the warning is barely audible. When conditions, such as grooved pavement or loud cabin noises, such as when a window or moonroof is open, the warning is completely in-audible. Similarly, the warning message displayed is not readable within the 0.5 - 1.0 sec (best estimate) that it is shown, as it is several lines of text - a distraction in itself. The disabling occurred during times when this ADAS feature is most value, cruising at highway speeds in heavier traffic - a time when automatic speed control and braking, along with maintaining a clear distance, are all invaluable to driver safety.

In my 2024 Tuscon, Hyundai has connected their cruise control to their driver assistance function. This system includes a camera on the steering column that watches the drivers eyes. If for any reason, they cannot see your eyes they will shutdown cruise control without warning. This can be caused by simply wearing sun glasses. So this forces the customer to choose between two safety features. Cruise control which we all know has signifcant safety implications reducing stress fatique, etc. and bypass all the driver assistance systems. There are people who are putting black tape over the camera and disabling DAS so they can use their cruise control due to the inability to wear sun glasses when heading west (obviously even within a curve, so it shuts down unexectedly in the curve). Surely that is not an acceptable solution. Hyundai should add an option to ignore the eye checks while using the cruise control but so far they have totally ignored it. You can google for "Hyundai cruise control sunglasses" and will see a lot of complaints and people disabling safety features. Obviously there is no specific event, this is happening all the time in the US.

First incident was July 2025 . Car had 1300 miles. Would not accelerate over 25 miles an hour. Made an appointment with Route 60 Hyundai in Vero Bch, Fl. They could not find anything wrong. (invoice # [XXX]) Second time [XXX]. 3009 miles on the speedometer. The car would not accelerate over 4mph. After several minutes acceleration was possible. We will once again return to Route 60 Hyundai. Car could not get thru a busy intersection. Very dangerous. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Concern: DAW Driver Monitoring System False alerts shuts down cruise control. Safety issue when passing on interstate and suddenly the cruise shuts off and has to be reset. This warning sometimes goes off randomly and not due to driver attentiveness. If my arm is in top of steering wheel it blocks camera and wearing certain types of sunglasses. This system is asking the driver to not put his arm on top of wheel which is ridiculous.

The message “Consider taking a coffee break” will pop up just 15 minutes into a trip. This message beeps prior to flashing on the screen which causes us to take our eyes off the road to determine what is beeping and continues to “alert” us often during our travels. Hyundai has not provided a way for this warning to be deactivated. Hyundai has way too many messages beeping and appearing on the screen that causes distractions and has not provided a way to turn them off. As for the speed control, my ophthalmologist suggested I wear dark sunglasses due to issues I have in bright sunlight. The speed control will actually turn off if I wear dark sunglasses because the onboard camera cannot see my eyes. Also, the speed control will turn off if I’m making a turn and my arm gets in the way of the camera. This is extremely dangerous that the speed control just stops. We also will get beeps and a message on the screen if the camera cannot see our eyes, even when we are looking straight ahead. Again, this causes us to see what is beeping and what the message says. This is a distraction that causes us to take our eyes off the road. Terrible design.

There is a sensor on the steering column that turns off the cruise control if it can’t see your eyes. This happens abruptly and slows the car down. It will cause a rear end collision if not taken care of! Has been to the dealer 5 times.is available for more inspection. There is a sensor on the steering column that turns off the cruise control if it can’t see your eyes. This happens abruptly and slows the car down. It will cause a rear end collision if not taken care of! I have more documentation from the dealers but I don’t have room to upload. Yes dealers have reproduce the issue. Manufacture has been notified and had us take to dealers. Warning message on dash but no time to react.
