2025 Hyundai Elantra Driver Assist & ADAS Problems

The contact rented a 2025 Hyundai Elantra. The contact stated that while driving 80 MPH with the cruise control activated, the braking system failed to engage, causing the contact to manually depress the brake pedal to stop the vehicle. A dealer was contacted. The vehicle was not taken to a dealer or independent mechanic to be diagnosed or repaired. The failure had occurred three times. The manufacturer was notified of the failure and opened a case. The approximate failure mileage was 10,308.

The “consider taking a break” is extremely distracting and this feature is unable to be disabled. Spurious alarms create a distracting, unsafe driving condition, contrary to what it is aiming for.

The car has a "take a coffee break"warning light that dings when it comes on. It will randomly go off even if you don't leave your lane or cross a line. It's distracting and sometimes will go off if you have to veer around an object in the road making you think there's some other issue that you have missed, like a car beside you or something. Other times it will go off if you're just driving down the middle of the lane but wind is shaking the car, distracting you making you think there's an actual issue. There appears to be no way to turn this "feature" off and in traffic is very distracting and could cause an accident.

RE: 2025 HYUNDAI ELANTRA LIMITED AUTOMATIC BRAKE CONTROL On a recent road trip, the automatic brake system activated twice in a manner that could have put our lives at risk. The list below applies to both incidents: On a four lane interstate highway at approximately 70 mph. Wide, level median. Full daylight. Dry pavement. Unlimited visibility. Flat landscape. No objects in the median or anywhere abutting the lanes. No wind. No car for at least a mile ahead of us, none next to us. Brakes were suddenly applied by the “assist.” Brakes so violent we were pushed forward in our seatbelts. Second incident so violent and persistent I started to pull off to the side of the lane for fear of being struck from behind. In both incidents, the “assist” eventually quit. Had this happened with a semi behind us unable to slow down fast enough we could have been severely injured or killed. Apparently, the “assist” cannot be turned off for good. Since the above incidents, we did try to shut off the’”assist" but it was back in operation the next time we started the car. This situation needs to be addressed. The “assist” seemed to want to assist us into an early grave.

The “consider taking a break” warning pops up way too frequently and cannot be disabled. It completes the exact opposite of its intended purpose, and actually is a danger to driving, as it diverts your attention away from the road. It has no maximum warnings either - so it can divert your attention and distract you every few minutes for as long as you are driving.

I keep getting a warning that pops up saying “consider taking a break”. It’s very distracting and there’s no way to turn it off. Please give us a way!

The “Consider Taking a Break” notification while driving is incredibly loud and distracting even when on the lowest setting and can repeat up to every 20’ while driving. While it is helpful to take a break on extended trips, it is not reasonable to stop that frequently. On long drives, this alert becomes nothing more than an irritant and distraction. There is no option to disable or silence this warning outside of turning off ALL safety notification sounds.I will probably do that just to avoid this notification, which compromises all of the other safety notification sounds that are far more important (ex. Lane departure, forward collision, and blind spot detection).
